(4) Receipt, transfer, and disposal of aviation equipment.

(5) Current software version installed in the aircraft data systems and/or survivability electronic countermeasures and avionics systems line replaceable units (LRUs).

(6) Aircraft engines and auxiliary power unit (APU) operating hours, history recorder/counter readings, and all significant engine events.

c. Deficiency reports. Various deficiency reports recommend corrections, changes and improvements to aircraft, associated equipment, mission equipment, and maintenance procedures contained in technical publications (see chaps 3 and 5).

1–5. Tables and appendixes

a. Information in tables 1–1 through 1–21 applies to aviation equipment, and UAS, forms, and records in this pamphlet. These tables contain the codes used on forms and records throughout this pamphlet. Units and activities shall use these tables for completing operational, maintenance, and historical forms described in the chapters 2–5.

b. Information in appendixes applies to aviation equipment and UAS data/forms and records described in chapters 2–5.

1–6. General instructions

a. Army aviation records, information and reports require unique management to support the safety and airworthi-ness of aircraft, UA and all associated subsystems and components. To accomplish this goal the specifications outlined throughout this pamphlet will be adhered to. Minimizing the use of paper and time to prepare aircraft logbooks for next day missions is an ongoing effort. This pamphlet covers procedures for filling out forms and records manually or

1DA PAM 738–751 • 28 February 2014 utilizing the current aviation LIS to help accomplish this effort. Aviation units and activities, to include DOD contractors providing aircraft, UAS subsystems and new, overhauled, recapped, or rebuilt reportable components and modules are required to use the current aviation LIS which authorizes them to populate use specific automated forms and records. All other aviation units and activities, including DOD contract support maintenance activities not fielded an aviation LIS, shall use hard copy (paper). DA Forms and records as prescribed in this pamphlet. The instructions for forms and records also apply to aviation LIS generated forms and records, unless specifically stated otherwise. Unless specific instructions state otherwise, the following shall apply:

(1) Official forms shall not be changed or altered. Locally devised forms or records may not be used as substitutes for the forms and records in this pamphlet. When forms do not meet particular requirements, a written request for deviation should be submitted to the Deputy Chief of Staff, G–4 (DCS, G–4) (DALO–ORR–ER), Washington, DC 20310–0505, or U.S. Army Aviation and Missile Command (AMSAM–MSI–L), Redstone Arsenal, Huntsville, AL 35898–5000 or e-mail to usarmy.redstone.usamc.mbx.immc-tamms-a-policy@mail.mil.

(2) All form entries (exceptions: personal signatures, initials, and the technical inspector’s (TI) stamp) shall be typed or printed.

(3) Logbook and maintenance form and record entries shall be made using black ballpoint pen, black lead pencil, or shall be electronically generated by LIS systems (see chap 2–5) (such as: the Army Publishing Directorate (APD) Forms Program).

(a) A black lead pencil shall be used to enter the total number of pages on manually maintained forms.

(b) A black ballpoint pen shall be used to manually enter status symbols on hard copy forms.

(c) Only black waterproof ink shall be used on materiel condition tags and labels for preservation purposes.

(4) Overprinting of forms and use of electronic forms are authorized when information is repeated; for example, the heading information or listing inspection items when the form/data are used for a particular purpose more than once or routinely.

(5) Recreate or regenerate manual forms and records only when the original is lost, damaged, or the information is illegible. Forms or records shall not be recreated for neatness.

(6) Historical forms will not be recreated when aircraft, aircraft subsystems, associated equipment, LRUs, or components are repaired, overhauled, recapped, or rebuilt. Forms will be updated with new data and new forms added as required. The AMCOM MCDS program and LIS systems have the capability to print copies of historical forms.

(7) New forms or records shall not be started until there is an entry; for example, a new manufactured component does not require a DA Form 2408–5–1 (Equipment Modification Record (Component)). The form will be established when something major has happened to the component; such as, a SOF, aviation safety action message (ASAM), or aviation maintenance action message (AMAM).

(8) “Not applicable,” “not required,” or “N/A” entries shall be left blank.

(9) All maintenance actions resulting from deficiencies, faults, failures, problems in design, operation, maintenance, manufacture, overhaul, recap/rebuild, and recommendations for improvement of aircraft and aviation-associated equip-ment shall be entered into the LIS System or on the manual forms or records that apply.

b. The instructions contained in this pamphlet shall take precedence when conflicts arise between related publica-tions and this pamphlet. Units or activities discovering conflicts between related publications and this pamphlet shall prepare a DA Form 2028 (Recommended Changes to Publications and Blank Forms) AMCOM (AMSAM–MSI–L), e-mail to usarmy.redstone.usamc.mbx.immc-tamms-a-policy@mail.mil.

c. If a unit or activity discovers an error after sending a form to AMCOM (such as DA Form 2410 (Component Removal/Repair/Install/Gain/Loss Record) or DA Form 2408–19–3 (Engine Component Operating Hours Record), whether electronic or hard copy, the AMCOM DA Form 2410 Hotline shall be contacted at Defense switched network (DSN) 897–2410 or commercial (256) 313–2410 or 1–877–511–8139, fax DSN 897–2075 (or commercial (256) 3 1 3 – 2 0 7 5 ) , o r e - m a i l ( u s a r m y . r e d s t o n e . u s a m c . m b x . i m m c - d a t a 2 4 1 0 @ m a i l . m i l ) t o h a v e t h e r e c o r d i n t h e M C D S corrected.

d. First, read the policy in the text. Fill out the forms showing the aviation equipment, unit, and status. To assist in filling in the status, fault, and correcting information, see definitions of status symbols and action codes contained on DA Form 2408 (Equipment Log Assembly (Records)) in chapter 2. The policy and instructions will take precedence when conflicts exist between the form and the example.

e. If a form or record must be reconstructed, all current information from the old form shall be entered on a new form.

(1) If a form or record has a personnel identifier (PID) block and the person who originally put a PID on the form is not available (such as, permanent change of station, expiration term of service, deployed, deceased), the person reconstructing the form shall enter previously complied with (PCW) and his/her own PID (usually the Army Knowl-edge Online (AKO) user name or, if not assigned an AKO user name, use first name, middle initial, and last name), or LIS computer generated PID.

(2) When the information is not available for a specific block of a form, commanders or commanders designated representative shall ensure everything possible is done to retrieve the information. Do not use "UNK" and "N/A" on DA Form 2408–16 (Aircraft Component Historical Record), DA Form 2408–16–1 (History Recorder, Component, 2 DA PAM 738–751 • 28 February 2014

Module Record), DA Form 2408–16–2 (Auxiliary Power Unit and Component Record), or DA Form 2410. If missing historical information is required, use the instructions in paragraph 1–13.

f. If a life cycle-managed (tracked reportable) component, LRU, or module arrives in the unit or activity without a DA Form 2410, historical records, or a materiel condition tag attached, the instructions in paragraph 1–14 shall be followed.

g. Commanders may execute disciplinary action when data/forms or records are purposely and/or intentionally lost, falsified, damaged or destroyed. .

Note. There is no requirement to rewrite TMs when recording related maintenance actions on forms and records. A brief description of the maintenance action performed is sufficient.

h. Recording maintenance events for readily visible assemblies, such as batteries, do not require multiple entries;

make one entry on the DA Form 2408–13–1 (Aircraft Inspection and Maintenance Record) or DA Form 2408–13–3 (Aircraft Technical Inspection Worksheet). For example, record in the fault/remark block, "Battery removed," and in the corrective action block, "Reinstalled battery." Components and safeties not readily visible require a separate entry and inspection before reassembling. Components require an entry when the TM directs a specific torque value applied.

Note. There is no requirement to underline the torque value on the form.

i. Follow the guidelines below when entering calendar dates and clock times:

(1) Calendar date format in this pamphlet shall be in the order of day, month, year (ddmmmyyyy) for paper; Army

LIS systems shall use default format. For example, record 3 Oct 06 as 03OCT2006. Julian or ordinal dates may be used on DA Form 2407 (Maintenance Request)/DA Form 2407–1 (Maintenance Request Continuation Sheet) per specific instructions on the form.

(2) Use the 24-hour clock when entering clock time format. For example, display 4 minutes after 9 o’clock AM as 0904, or 10 minutes after 1 o’clock PM as 1310.

j. When entering aircraft hours on a manual DA Form 2408-16, DA Form 2408–20 (Oil Analysis Log), or DA Form 2410, the hours may be rounded up or down to the nearest whole number. For example, 1375.4 hours rounds down to 1375 hours and 1375.5 hours rounds up to 1376 hours.

k. Abbreviations and acronyms are authorized. Use only acronyms from HQDA and/or AMCOM approved/author-ized aircraft, UAS subsystems, and/or associated equipment TMs.

l. l. The terms noun, noun abbreviation, noun nomenclature, and name refer to the same basic identification of a repair part, component, module, LRU, or end item.

m. Use only English units of measurement (see table 1–21).

n. Aircraft serial numbers shall be recorded without hyphens or dashes. Aircraft serial numbers shall contain only seven numerical characters. If the serial number contains less than seven numerical characters, add a zero “0” or zeros following the first two characters (FY procurement) of the serial number. For example, record 84–23456 as 8423456, record 85–6789 as 8506789, or record 90–123 as 9000123. Record serial numbers, UAS equipment, training devices, simulators, repair parts, components, modules, LRUs, systems, and subsystems as listed on the equipment data plate.

Note. Some automated systems remove dashes or leading zeros from serial numbers once they have been entered. This practice is acceptable and is not an error.

o. The PID is the minimum requirement to certify entries on all forms and records, and data entered in LIS systems governed by this pamphlet.

(1) The PID for manual forms and records will consist of a person’s AKO user name; if the person is not assigned an AKO user name, use the first name, middle initial and last name.

(2) Commanders’ designated representatives may use their signatures (first initial and last name) along with their AKO user name or, if not assigned an AKO user name, use the first name, middle initial and last name on paper forms and records.

p. Maintenance work hour consists of the time it takes to complete a maintenance inspection, task, action, or technical inspection, including the time required to fill out forms and records. Record these hours in the man-hour block as hours and tenths of hours (see table 1-14).

1–7. Roles

a. Commanders and persons in equal management positions of DOD contract support maintenance activities may appoint a designated representative for commander level entries on forms and records in their absence. Commanders shall designate representatives in writing.

b. Commanders and persons in equal management positions of DOD, contract support maintenance activities shall ensure all maintenance actions resulting from deficiencies, faults, failures, problems in design, operation, maintenance, manufacture, overhaul, recap, rebuild, and recommendations for improvement of aircraft, UAS subsystems, and aviation associated equipment are entered on the forms or records, as applicable.

c. Aircrew members, mechanics, TIs, maintenance managers, record clerks, supervisors, and commanders at all

3DA PAM 738–751 • 28 February 2014 levels of maintenance, including DOD contract support personnel and activities, are responsible for maintaining forms and records in accordance with this pamphlet.

d. Mechanics, maintenance managers, TIs, and DOD contract support personnel and activities shall use only approved TMs, electronic TMs (ETMs), interactive ETMs (IETMs), and related publications for all maintenance procedures.

e. The manufacturer of new aircraft, UAS subsystems, aircraft training devices and/or simulators, and reportable components, LRUs, or modules is responsible for completing all applicable forms, records, and supply condition tags and/or labels covered by this pamphlet (see app A).

f. Contract support maintenance activities providing logistic support to nonstandard Army aircraft may use forms and records in this pamphlet.

g. Units that have not been fielded LIS and are using the manual method of record keeping, shall maintain a list of the names and signatures of all personnel performing maintenance and of the commander’s designated representatives.

This information shall be maintained for 6 months after the individual leaves the unit. Units and activities shall—

(1) Safeguard all forms and records.

(2) Not change the aviation LIS master component legitimate code files (LCFs) without prior approval from

AMCOM or the DCS, G–4.

(3) Maintain legible, accurate, and complete forms and records.

h. All units and activities shall establish a logbook control program.

(1) File aircraft logbooks (hard (paper) copy forms and/or laptop computer) in the flight platoon, unit, or activity maintenance office when aircraft are not flying (see chap 2).

(2) Place responsibility for maintaining and filing the logbook with the assigned crew chief or mechanic.

1–8. How to use status symbols

a. Status symbols shown on forms and records indicate the seriousness of faults, failures, deficiencies, related maintenance actions, and known or potential safety hazards to include those imposed in a nuclear, biological or chemical (NBC) environment. They show the condition, readiness operation, service, inspection, and maintenance actions of aircraft, aircraft system/subsystems, UAS subsystems, or associated equipment. There are eight status symbols used. Five show the condition of the aircraft, system, or associated equipment: Grounding X, circled X, horizontal dash ( - ), diagonal ( /,) and last name initial. Three status symbols are used for contaminated aircraft, and UAS: Circled N, circled B, and circled C Units and activities shall enter status symbols as applicable regardless of the insignificance of the fault or the time required for the correction.

(1) Grounding X status symbol. Grounding X indicates a fault, deficiency, or condition (actual or potential) exists making the aircraft, system, and/or subsystem or associated equipment unsafe to operate and/or fly. The following policy applies:

(a) Operating aircraft on the ground is authorized when the status symbol is a grounding X to facilitate troubleshoot-ing and maintenance with the stipulation that the grounding X condition does not affect safe operation.

(b) Assign the status symbol grounding X to a fault in a system or subsystem (such as the Hellfire missile system) only when the system or subsystem is disassembled and/or removed, resulting in the current system or subsystem configuration or condition unsafe for ground or flight operations.

Note. If a system or subsystem (such as the Hellfire missile system) does not affect safe flight or ground operations in an inoperable and/or disabled condition, enter a circled X status symbol restricting that system and/or subsystem from use.

(c) When a grounding X status condition is discovered and the same condition could potentially occur in other aircraft, the Commander or designated representative shall immediately inspect other aircraft of the same mission design series (MDS) for the unsafe condition. Commanders or designated representatives shall enter the grounding X status symbol on other aircraft found with or potentially having the unsafe condition. Units and activities shall prepare and submit a Category I SF 368 on the unsafe condition when it meets the rules in paragraph 3–2.

(d) When an installed system that is necessary to execute an underlined, immediate step, emergency procedure in the aircraft’s operator’s manual is not completely functional or a condition exists that may prevent it from complete functionality. An example would include a fault stating “wheel brakes soft and/or spongy.” Wheel brakes are necessary to execute the underlined, immediate step, emergency procedure for tail rotor malfunctions requiring a run on landing to enable a safe recovery of the aircraft. Therefore the aircraft shall be grounded until the brakes are repaired to a completely functional state.

(2) Circled X status symbol. A circled X indicates a fault, deficiency, or condition (actual or potential) exists allowing the aircraft to fly under specific restrictions or limitations as specified or directed by higher authority, or as directed locally, until corrected. A circled X status symbol applies to the following situations:

(a) When a condition exists on the aircraft, system, or aircraft equipment that restricts or limits operation to a specific procedure, component, system or subsystem used during maintenance, ground, ground taxi, hovering flight or flight operations, but allows for safe operation when disabled. For example, an aircraft with an inoperable landing light would have a status of circled X restricting the aircraft from night flight. If any restricting condition could potentially

4 DA PAM 738–751 • 28 February 2014 occur on other aircraft, the commander or designated representative shall inspect those aircraft. Status symbols for affected aircraft shall change as required. The person finding the fault, deficiency, or condition shall also prepare and submit a Category I deficiency report per paragraph 3–2, as required.

(b) When a SOF, ASAM, and/or AMAM message, MWO, RSN, AWR, or other directive requires operating aircraft within the restrictions and/or limits stated in the message or directive, for example, airspeed limitations, operating procedures, or weapon system duty cycles.

(3) Horizontal dash ( - ) status symbol. A horizontal dash ( - ) symbol indicates that the condition of an aircraft, system, or aviation equipment is unknown. This status symbol indicates a dangerous condition potentially exists and corrective action is required as soon as possible. A horizontal dash symbol applies to the following situations:

(a) When a scheduled maintenance inspection, special inspection, component or module replacement, maintenance operational check (MOC) is required or desired, a routine MWO is overdue application, a routine technical bulletin or maintenance mandatory or operational ASAM or AMAM is received, or a maintenance test flight (MTF)/Functional Check Flight (FCF) is required or desired.

(b) When maintenance actions listed above are due or started early.

Note. Enter a dash ( - ) when the inspection is due. The inspection is due when the crew operating the aircraft completes their briefed mission and current aircraft hours are at the inspection interval, but not past the allowed inspection window outlined in TM 1–1500–328–23 or the end of the duty day, whichever comes first. The window in TM 1–1500–328–23 only applies when the commander extends the briefed flight crew’s mission and that briefed crew began the mission prior to the inspection interval. Once that crew completes the briefed mission or end of the mission day, the unit and/or activity shall complete the inspection prior to commencing aircraft flight operations. Do not begin aircraft flight operations when the current hours are at or past the inspection due interval. Commanders should consider operating aircraft with an inspection due as a high-risk mission. Commanders are responsible for adhering to all inspection intervals.

(4) Diagonal ( / ) status symbol. The diagonal status symbol indicates a known fault or deficiency exists in materiel installed on aircraft, system, or aviation equipment. It also shows that an unsatisfactory condition exists on aircraft, system, or associated equipment that is not urgent or dangerous enough to ground the aircraft or stop the use of the aircraft, system, or associated equipment. The diagonal is used in the following ways:

(a) To describe the condition of the aircraft, system, or associated equipment on the forms that apply (see chap 2).

(b) When a SOF, ASAM, or AMAM has been received that requires an inspection of a component and the inspection shows that the component must be replaced by a specified date then the new write-up showing the removal required by date shall have a diagonal status symbol.

(5) Circled N, circled B, and circled C status symbols. A circled N, circled B, and circled C indicate the aircraft was flown, operated, or stored in a NBC environment and is potentially hazardous to personnel.

Note. Decontaminate aircraft per this publication in appendix B, FM 3–11.5, and appropriate TMs.

b. Condition status symbols used in this pamphlet serve two purposes:

(1) Indicate the condition and status of manned and unmanned aircraft, systems, subsystems and associated equip-ment aboard the aircraft.

(2) Establish a standard way of identifying the seriousness of faults and conditions of manned and unmanned aircraft, systems, subsystems and associated equipment.

Note. Initialed status symbol shall appear only on manually entered paper forms (see chaps 2, 3, 5), not applicable to status symbols in automated systems.

c. Never erase or alter a status symbol once it is entered. Specific uses of status symbols are contained in the instructions for filling out the various aircraft forms and records in chapters 2 through 5. A status symbol in a condition status block shows the individual’s opinion as to the seriousness of the fault, deficiency, or condition. No one may direct a person to change this symbol.

d. Correct status symbols entered or initialed in error as follows:

(1) When a dash (-) or diagonal ( / ) symbol is entered in error on DA Form 2408–13–1 or other maintenance forms

(see chaps 2, 3, 5), the person who made the entry or initialed the status in error shall enter the following statement in the Correcting Information Block: "Status symbol entered in error, disregard" or "Status symbol entered in error, see entry below" or "Status initialed in error, reentered below" and his or her AKO user name in the PID block. For status symbols entered in error reenter the fault or deficiency and proper status symbol in the next open Fault Information block on the form.

(2) When a grounding X or circled X is entered or initialed in error on DA Form 2408-13-1 or other maintenance forms (see chaps 2, 3, 5), the person who made the entry shall enter the following statement in the Correcting Information Block, "Status symbol entered in error, disregard" or “Status symbol entered in error, see entry below" or "Status symbol initialed in error, reentered below" and their AKO user name in the PID block. Have the commander or a designated representative (usually a TI) verify the incorrect status symbol or the incorrectly initialed status symbol by entering “Insp OK,” their signature and AKO user name (TI personnel identifier (TIPID)) in the Correcting Information Block. The designated representative shall then enter their last name initial over the status symbol in the Fault Information Block. Reenter the fault or deficiency with the proper status symbol in the next open Fault Information Block.

5DA PAM 738–751 • 28 February 2014

(3) The person finding an error in the System Status Blocks on DA Form 2408–13 (Aircraft Status Information Record) shall explain the error in the next open Fault Information Block of DA Form 2408–13–1 (this applies only to manual paper systems). The explanation shall include the aircraft or mission related equipment status symbol, the block that is in error and the AKO user name of the person correcting the error, in the Fault Information Block. For example, for “dash symbol in aircraft (ACFT) top block 2 entered in error,” enter in the Correcting Information Block a statement showing corrective action that consists of a person’s AKO user name in the PID block. For “Status adjusted,” a status symbol is not required in the Fault Information Block for these entries. Enter the correct status symbol in the next open System Status Block on DA Form 2408–13, if it applies.

(4) Correct status symbols entered or initialed in error on DA Form 2408–13–2 (Related Maintenance Actions Record), block 8, by making an entry in block 10 stating, “Status symbol (entered or initialed) in error” and enter your AKO user name in block 11. Re-enter the related maintenance action with the correct status on the next open line of the form. Correct status symbols in Block 1 initialed in error by making an entry in Block 9 stating, “Status initialed in error.” This entry shall not require a status symbol in Block 8 or an action entry in Block 10.

(5) Any maintenance or quality assurance personnel within any aviation maintenance activity, who believes that the fault, deficiency, or condition is more serious than depicted, has the responsibility to change the current status symbol to a more serious status symbol. They shall enter “Status symbol changed to (enter status symbol) see entry below” and their AKO user name (PID) in the Correcting Information Block. On the next open Fault Information Block, enter the new status symbol and reenter the fault or deficiency. The person changing the symbol shall place their AKO user name in the Fault Information Block to take responsibility for the status symbol change and entry.

(6) If the commander or person in an equal position in DOD contract support maintenance activities considers the condition of the aircraft or aviation associated equipment less serious than indicated by the status symbol, they may change the symbol as desired. Commanders or persons in an equal position in DOD contract support maintenance activities should not delegate the authority to change the status symbol to a less serious status symbol. In the Correcting Information Block, enter “Status symbol changed to (enter status symbol); see entry below,” enter your AKO user name in the PID and TIPID Blocks. On the next open Fault Information Block, enter the status symbol in the Status Block and reenter the fault or deficiency, and enter your AKO user name in the PID block. Update the System Status Block on DA Form 2408–13.

Note. These procedures also apply to DA Form 2408–13–3.

1–9. Clearing status symbols

a. When a grounding X or circled X condition is corrected a qualified designated representative appointed by the commander, activity supervisor, or an equal management or supervisory personnel in a DOD contract support maintenance activity in writing, must inspect the completed action.

(1) The mechanic making the corrective action shall fill out the Correcting Information Blocks, including the PID Block of DA Form 2408–13–1.

(2) Inspect the corrective action taken. If the action taken is satisfactory, the inspector shall enter a statement, “Insp OK,” and their signature in the Correcting Information Block of DA Form 2408–13–1 (manual recordkeepers only).

Manual recordkeepers have the authorization to use an inspector’s stamp instead of the statement "Insp OK" and signature. The inspector shall also enter their AKO user name in the TIPID block.

Note. If an inspector’s stamp is used, the stamp will be no larger than 1/2 inch in diameter.

(3) The inspector of the corrective action shall place his or her last name initial over the status symbol in the Fault Information Block of DA Form 2408–13–1 and update the proper System Status Block of DA Form 2408–13, if required (manual recordkeepers only).

b. When a designated representative or authorized TI does any part of the corrective action work to clear a grounding X or circled X, a different designated representative or TI shall inspect and sign off the corrective action.

That inspector shall enter their AKO user name in the TIPID Block.

Note. These procedures also apply to DA Forms 2408–13–2 and DA Form 2408–13–3.

c. Only technical inspectors assigned to the unit or activity’s quality control (QC) office shall sign off on initial status symbols generated by SOF messages, ASAMs, AMAMs, MWOs, RSNs, and other one-time inspection messages that call for a visual inspection of the aircraft, UAS subsystems, aircraft records, associated equipment and/or specific historical record entries. If other work is required to complete the inspection, any other TI may sign off on those status symbols as applicable. Perform inspector entries on DA Form 2408–13–1 per paragraph 1–9a(2) and 1–9a(3).

d. Occasionally, the action taken on some cleared status symbols on DA Form 2408–13–1, DA Form 2408–13–2, or DA Form 2408–13–3 does not correct the fault entirely or satisfactorily. If an MOC demonstrates the action taken did not correct the fault, leave the Correcting Information Block adjacent to the "MOC Required" entry blank. Enter faults discovered preventing the completion of the MOC in the next open Fault Information Block with the applicable status symbol in the Status Block. If correcting the fault preventing the correction of the original MOC requires an MOC, make a separate entry for that MOC on the next open Fault Information Block. After completing the MOC for the fault that prevented you from performing the original MOC, complete the original MOC and record it per paragraph 2–11.

6 DA PAM 738–751 • 28 February 2014

e. Designated representatives can sign off on a grounding X status symbol inspected fault or deficiency found to be within the limitations. The designated representative can clear the entry by entering in the Correcting Information Block, "Insp OK," then entering their AKO user name in the PID and TIPID blocks.

f. Clearing a circled X status symbol for a one-time evacuation mission of an aircraft requires no maintenance action, and there is no requirement for the entry to be inspected by a designated representative.

1–10. Evacuating aircraft with a grounding X condition The commander, a designated representative, or an equal management supervisor in a DOD contract maintenance support activity may authorize a one-time evacuation mission for an aircraft with a grounding status of X when the benefits of the evacuation flight outweigh any degree of risk involved as follows:

Note. One-time evacuation missions (recovery missions) allow the commander flexibility to authorize more than one fuel stop when recovering an aircraft with grounding X condition. The aircraft shall stop at the first maintenance facility that shall support the maintenance repairs required. The commander is responsible for the risk assessment of each leg of the mission. Commanders shall not use this authorization to return an aircraft with grounding X condition to home station unless it is the first maintenance facility that shall support the maintenance repairs required.

a. Enter this statement in the Correcting Information Block of DA Form 2408–13–1: “Status symbol downgraded to a circled X; see entry below.” The person making this entry shall enter their AKO user name in the PID block that applies (PID Block or TIPID Block). Manual record keepers may enter their signature after the statement.

(1) Enter a circled X in the next Fault Information Block and change the System Status Block on DA Form 2408–13.

(2) Enter this statement in the circled X Fault Information Block: "Aircraft cleared for a one-time evacuation mission from (enter current location) to (enter location of nearest maintenance facility that will support the required repairs)" and complete all portions of the Fault Information block that apply to include the PID Block. Manual record keepers may sign their name following the entry.

b. After completing the one-time evacuation mission, the pilot authorized by the commander or designated repre-sentative performing the one-time evacuation mission shall enter in the Correcting Information Block: “One-time evacuation mission completed, status symbol upgraded to a grounding X see entry below.”

(1) The pilot shall enter their AKO user name in the Correcting Information PID Block. Enter a TI’s AKO user name in the TIPID Block.

(2) The pilot shall enter the grounding X status symbol in the System Status Block on the next open box on DA Form 2408–13 and the status box in the Fault Information Block of DA Form 2408–13–1. Reenter the original fault and the pilot’s AKO user name in the Fault Informatio PID Block.

1–11. Maintenance test flight and/or functional check flight verification of aircraft on grounding X status symbol

a. The commander or a designated representative or an equal management supervisory person in a DOD contract maintenance support activity may authorize a maintenance test flight for verification, providing an acceptable degree of risk exists when ground tests shall not duplicate an in-flight grounding X status deficiency.

(1) Enter “Status symbol changed to a dash (-); see entry below” in the Correcting Information Block. Manual recordkeepers making this entry shall enter their signature after the statement. TIs shall enter their AKO user in the TIPID Block in the Fault Information Block of DA Form 2408–13–1.

(2) Enter in the next open the Fault Information Block, “Aircraft cleared for a maintenance test flight to verify (reason for test flight).” Manual record keepers shall sign their name following the entry. Complete all portions of the Fault Information Block that apply, to include PID.

(3) Enter a…
