1.1.1.1 Unless otherwise specified, the term AEROSPACE EQUIPMENT in this technical order refers to weapon systems and equipment such as aerospace vehicles, equipment, missiles, nuclear weapons, Test Measurement and Diagnostic Equip-ment (TMDE), trainers, training equipment, engines, Flight Support Equipment (FSE), industrial plant equipment, and all related Support Equipment (SE). This TO is applicable to all organizations maintaining this equipment.

1.1.1.2 Two services exist in the Department of the Air Force (DAF), the U.S. Air Force (USAF) and the U.S. Space Force (USSF). The MAJCOM, formerly designated as Air Force Space Command (AFSPC) was redesignated as the USSF.

Separately, additional Field Commands (MAJCOMs) were created under the USSF; Space Operations Command (SpOC), Space Training and Readiness Command (STARCOM), and Space Systems Command (SSC). For the purpose of this TO, any reference to MAJCOMs will encompass all MAJCOMs including USSF, unless otherwise indicated. USSF may issue supplemental guidance that is applicable for its respective mission areas IAW the procedures outlined in TO 00-5-1.

1.1.1.3 MAJCOMs may supplement 00-20-series TOs as required. Refer to TO 00-5-1 for MAJCOM, Base, and Unit Supplement requirements. For the purpose of maintenance policy, the lead commands are Air Combat Command, Air Mobility Command, Air Force Special Operations Command, Air Education and Training Command, Air National Guard, Air Force Reserve Command, Air Force Space Command, Global Strike Command and Air Force Materiel Command.

1.1.1.4 Air Force agencies will not furnish maintenance data in any form to contractors unless granted by the applicable weapon system Controlling Distribution Office (CDO) in accordance with DoDI 5230.24, Distribution Statements on Tech-nical Documents.

1.1.1.5 In 00-20-series TOs, the designation, GP/CC is used to represent the Maintenance Group Commander. At test sites or activities which do not have a GP/CC, it will be the responsibility of the Chief of Maintenance, Chief of Test Force Teams, Air Mobility Squadron Commander, Installation Team Chief or equivalent (as determined by the MAJCOM/A4) to ensure that the criteria of this TO is complied with.

1.1.1.6 Forward requests for waivers to this TO through MAJCOM maintenance policy to HQ AFMC/A4FI.

1.2 CONTRACTOR MAINTENANCE.

1.2.1 Operations Instructions. The contractor will provide the Air Force contract administration office with a list of personnel who are authorized to certify that Aerospace Equipment is safe for flight or use. This certification list should be kept to a minimum to meet mission requirements. Any changes to the list will be immediately forwarded to the contract administration office. The listing will specifically identify the personnel who are authorized to:

a. Sign exceptional releases.

b. Downgrade Red X or Red W conditions.

c. Sign off Red X or Red W symbol.

d. Certify operational capability (i.e. Safe-For-Flight Release).

e. Perform functional check flights (if applicable).

f. Update weight and balance records in accordance with TO 1-1B-50.

1-1

1.2.1.1 The contractor will develop and maintain a program to ensure that personnel are trained in the areas specified in the contract. The program will have provisions for contractor certification/recertification of personnel authorized to perform the specific functions or to operate various support equipment in accordance with DAFI 21-101 and other applicable directives.

1.2.1.2 The contract administration office will ensure that the contractor performs the maintenance management and documentation requirements prescribed in applicable TOs. In addition, the contract administration office will ensure that the applicable TOs are referenced as provisions in the contract.

1.3 TRANSIENT AIRCRAFT (TA) SECTION.

The TA Section recovers, services, inspects, maintains, and launches transient aircraft. Transient aircraft are those aircraft not assigned to a base that are en route from one location to another that may require routine servicing. Aircraft are not considered transient aircraft when deploying to, or staging from, any location for the purpose of flying sorties or conducting training, either with or without the necessary maintenance support from the aircraft’s home base. The Maintenance Opera-tions Center (MOC) coordinates specialist support for transient aircraft through appropriate squadrons. The TA Section NCOIC/Chief will complete reimbursement documentation for documenting maintenance servicing requirement and neces-sary billing information by completing an AFTO Form 726, Transient Aircraft Service Record (formerly AF Form 726).

Additional TA Section NCOIC/Chief responsibilities are outlined in DAFI 21-101.

CHAPTER 2

AEROSPACE VEHICLE INSPECTIONS

2.1 GENERAL.

2.1.1 Inspection Intervals. Intervals required for Air Force aerospace vehicle inspections are prescribed in applicable Mission Design Series (MDS) specific -6 TO maintenance manuals, item technical orders, inspection workcards, checklists, commercial manuals or depot engineering data. All requirements pertaining to inspections will normally be accomplished concurrently to avoid complications in scheduling and controlling the required maintenance. The inspection concepts for aerospace vehicles are periodic, phase, isochronal, Programmed Depot Maintenance (PDM), and aerospace vehicle manu-facturer maintenance. The GP/CC establishes necessary controls to ensure that the periodic, phase or isochronal inspections are accomplished at or near the scheduled due time as authorized in applicable TOs or approved waivers. GP/CC may increase the frequency or scope of scheduled inspections or individual inspection requirements, when required for temporary situations. Scheduling deviations of periodic, phase or isochronal inspections beyond what is authorized in aerospace vehicle specific technical manuals, must be approved through the Program Manager (PM) in coordination with the owning MAJ- COM. Scheduling deviations that effect PDM or aerospace vehicle manufacturer maintenance, must be approved through the PM, Lead Command, and owning MAJCOM.

2.1.1.1 When new inspection requirements are levied and the age or accrued time of the aerospace vehicles, systems, and components is less than the specified inspection interval, begin accomplishment of the new requirements at the prescribed interval. If the age or time is beyond the specified interval, accomplish initial inspections as soon as practical and regulate subsequent inspections accordingly. When requirements are added or changed for accessory items, determine operating time in accordance with Chapter 6.

2.2 INSPECTION REQUIREMENTS.

2.2.1 Recurring Maintenance. Each PM determines the inspection concept, establishes a recurring maintenance cycle and ensures adequate scheduling flexibility to bundle/align recurring maintenance requirements to the maintenance cycle.

2.2.1.1 Recurring maintenance requirements are published in MDS specific -6 TOs and/or inspection workcard decks, (e.g., pre-flight, basic post-flight, thru-flight, etc.). If specified by the acquiring activity, workcards may be developed as self-contained documents and only need to be referenced in the -6 inspection manual.

2.2.2 Inspection Concepts. The basic sub-elements for the periodic, phase, isochronal, PDM, and aerospace vehicle manufacturer inspection concepts are as follows (Table 2-1, Table 2-2, Table 2-3, Table 2-4, Table 2-5):

Table 2-1. Periodic Concept

Pre-flight (PR) Basic Post-Flight (BPO) Pre-Launch Inspection (PLI) or Walk-Around (WAI) Combined Pre-Flight/BPO (PR/BPO) End-of-Runway (EOR) Hourly Post-Flight (HPO) Thru-Flight (TH) Periodic (PE) Quick Turn (QT) Pre-Departure Service Check (PDSC)

2.2.3 Inspection Cycle. Lead commands may authorize aerospace vehicles to use a modified inspection workcard deck during contingencies, and increased readiness conditions. The PM designates and publishes workcards in conjunction with the Lead Command for use during these periods. Construct contingency decks to ensure all items impacting aerospace vehicle safety and reducing aerospace vehicle reliability are inspected. Accomplish the normal inspection workcard deck upon termination of this period.

2.2.3.1 Periodic, isochronal, phase, HSCs, HPOs, and commercial equivalent inspections are scheduled at equal intervals throughout the total inspection cycle, regardless of when inspections were actually completed. Do not exceed inspection intervals unless authorized by the MDS specific -6 TO or approved by the Lead Command and PM to meet mission essential requirements. If the interval is exceeded, use the appropriate Red symbol (specific exceptions will be in the appropriate TOs). Inspection interval extensions must be annotated using the Red Dash unless authorized for service tests and special projects by the PM and the Lead Command. Changes to prescribed inspection intervals, concepts or requirements will be made by the PM only after thorough analysis of data obtained from the Maintenance Information System (MIS) and from appropriate Reliability Centered Maintenance Analysis (RCMA).

2.2.3.2 Scheduled inspection requirements specified in publications other than MDS specific -6 TO are not applicable to components in an installed status. Inspection requirements for components not installed are contained in commodity and equipment manuals. If inspection requirements for installed items are listed in publications other than -6 (or -2 for missiles) TO, bring them to the attention of the PM, who will take action to integrate them into the applicable -6 (or -2) scheduled inspection and maintenance manuals. Aircrew Flight Equipment (AFE) not in an installed status and therefore not listed in MDS specific -6 TO, as defined in the Glossary, are exempt from these requirements.

2.3 SPECIFIED FLYING PERIOD.

The specified flying period begins with the first flight and continues for a period of hours as specified by the MAJCOM not to exceed 72 hours, unless authorization is granted by the PM and MDS specific -6 TO.

2-2

2.4 INSPECTION TYPES.

2.4.1 Pre-Flight Inspections. The PR is a flight preparedness inspection done in accordance with the MDS specific -6 TO or maintenance requirements manual (as applicable). The inspection includes visually examining the aerospace vehicle and operationally checking certain systems and components to ensure there are no serious defects or malfunctions.

2.4.1.1 A PR will be required prior to the first flight of the flying period or when the PR validity period has expired.

2.4.1.2 If not already specified in the MDS specific -6 TO, MAJCOMs may select a 24-, 48- or 72-hour PR validity period. Owning MAJCOMs may follow existing lead MAJCOM supplemental guidance.

2.4.1.3 The pre-flight validity period ends when the selected time period in Paragraph 2.4.1.2 has expired or when the specified flying period expires, whichever occurs first. MAJCOMs or MDS specific technical orders may be more restrictive.

2.4.1.4 When an aerospace vehicle is mobilizing for contingency operations, units are authorized to place the aerospace vehicle on alert status. It must be prepared in accordance with established TOs, accepted by an aircrew, sealed (if not conflicting with TO guidance), remain under the control of operations and be monitored by maintenance.

2.4.1.4.1 Accomplish a complete PR prior to sealing the aircraft.

2.4.1.4.2 A new PR is not required during the alert period or as long as the aircraft is launched directly from alert status regardless of the PR validity period.

2.4.1.4.3 Upon termination of alert status, accomplish a new PR if the validity period has expired.

2.4.1.5 Pre-Launch Inspection or Walk-Around Inspection. The PLI and WAI are abbreviated pre-flight inspections and will be accomplished as required by the MDS specific -6 TO and/or MAJCOM supplement to this TO.

2.4.2 End-of-Runway Inspection. The EOR inspection is a final visual and/or operational check of the aerospace vehicle.

The PM in coordination with the Lead Command will list minimum inspection requirements in the applicable -6 TO and publish in an existing workcard deck.

NOTE

Aerospace vehicles that do not have a PM directed -6 EOR inspection requirement do not require this inspection.

2.4.2.1 The EOR is performed immediately prior to take-off at a designated location.

2.4.2.2 The purpose of the inspection is to detect critical defects that may have developed or have become apparent during ground operation of the aerospace vehicle.

2.4.2.3 Aerospace vehicles launched from alert status do not require this inspection. Alert Force Evaluations will not require an EOR and will be treated as Active Air Defense scrambles. However, alert aircraft launched for training missions from alert status will require an EOR inspection.

2.4.3 Thru-Flight Inspection. The TH is a between flights inspection and will be accomplished after each flight, when a turnaround sortie or a continuation flight is scheduled and a BPO inspection is not required. A TH is not required when aircraft are hot-pitted and immediately accomplish a turnaround or continuation sortie. This inspection is applicable when prescribed by applicable MDS specific -6 TO or maintenance manual. The TH consists of checking the aerospace vehicle for flight continuance suitability by performing visual examination and/or operational checks of certain components, areas or systems, according to established TOs to ensure no defects exist which would be detrimental to further flight.

2.4.3.1 Certain aerospace vehicles have TH requirements identified by special characters in applicable workcards. Other aerospace vehicles have separately published TH inspection workcards.

2.4.4 Quick Turn Inspection. The QT is an abbreviated thru-flight inspections authorized by MDS specific -6 TOs.

2.4.4.1 MAJCOMs may authorize QT inspections for aerospace vehicles resuming alert after flight or placing aerospace vehicles on alert at alert site locations. Owning MAJCOMs may follow existing lead MAJCOM supplemental guidance.

2-3

2.4.5 Basic Post-Flight Inspection. The BPO is a more thorough check than the PR or the TH inspections and is accomplished in accordance with the MDS specific -6 TO or maintenance manual for the aerospace vehicle.

2.4.5.1 The BPO will consist of checking the aerospace vehicle condition by performing visual examination or operational checks of certain components, areas or systems to assure that…
