Addendum 1. Airframe Components to be Removed Rev: Basic

Addendum 2. PDM and ACI Zonal Inspection Requirements Rev: Basic

1. GENERAL INSTRUCTIONS:

1.1. Scope: This Depot Maintenance Work Specification (DMSPEC) establishes the standard Depot Level Maintenance (DLM) rework requirements for the Air Force HH-60W model rotary aircraft. Upon completion of the Programmed Depot Maintenance (PDM) and Analytical Condition Inspection (ACI) DLM process, the 720-hour phase inspection requirement is satisfied.

1.2. Purpose: The primary purpose of the DLM program for the HH-60W aircraft is to accomplish aircraft structural inspections concurrent with zonal inspections at a depth and skill level greater than that available at organizational and intermediate maintenance levels. The zonal inspection will address structures, components, electrical wiring, hydraulic system components, fuel system components, and general integrity of the remaining items in that zone. Components (including engines, drivetrain elements, avionics, etc.) are removed to the extent required to conduct a detailed airframe inspection and will not be the subject of any depot-level maintenance though will be required to be inspected and maintained per Organizational/Intermediate (O/I) level maintenance per the applicable removal and installation procedures. Maintenance actions such as component-level rework or test, modifications, or special inspections, may be required on an over-and-above (O&A) basis per the Depot Maintenance Statement of Work (DMSOW).

1.3. Authority: This DMSPEC has been reviewed and approved by the AFLCMC/WIUE Rotary Wing Chief Engineer of the United States Air Force (USAF) and is authorized for use on all USAF HH-60W aircraft.

1.4. DLM Intervals: Under this concept, a fixed DLM inspection interval of 68 months has been established and incorporated into Technical Order (T.O.) 00-25-4.

1.5. DLM Process: This DMSPEC consists of nine sections and is organized to reflect the rework process illustrated in Figure 1 Typical DLM Process Flow. Each section addresses general policies and guidance for the DLM process. The work to be accomplished shall be identified as fixed tasks and variable tasks. Fixed tasks are those tasks which are predictable and consistent from aircraft to aircraft. The variable tasks are those which are not predictable and will vary from aircraft to aircraft.

Each section is identified accordingly.

Section 1 – GENERAL INSTRUCTIONS: Fixed general policies and guidance for the depot facility to manage the DLM process.

Section 2 – PREPARATION FOR INDUCTION: Fixed tasks and responsibilities to prepare the aircraft for DLM induction.

Section 3 – AIRCRAFT INDUCTION: Fixed tasks required to prepare the aircraft for inspection and maintenance.

Section 4 – STRUCTURAL INSPECTION REQUIREMENTS: Fixed inspection tasks required to locate and identify defects, including corrosion.

Section 5 – MAINTENANCE AND REPAIR: Variable tasks and set policies governing maintenance and repair required to correct defects and to accomplish all DLM requirements.

Section 6 – PREPARATION FOR DELIVERY: Fixed tasks required to prepare the aircraft for delivery.

Section 7 – AIRCRAFT DELIVERY: Fixed tasks and responsibilities to accomplish delivery of the aircraft to the gaining custodian.

Section 8 – QUALITY ASSURANCE: Fixed requirements for DLM inspection and quality control programs.

Section 9 – TERMS AND REFERENCES: List of nomenclatures, definitions, abbreviations, publications, and flight safety parts used within this DMSPEC.

1.6. Sequence of Work: The typical rework process is outlined below in Figure 1. This is a generalization of the DLM process from receipt of the aircraft from its owning activity to the final acceptance check flight and delivery to the gaining custodian. The organization of this DMSPEC parallels the sequence of work performed during the rework process.

Figure 1. Typical DLM Process Flow

1.7. Affected Aircraft: Aircraft that are encompassed by these DLM requirements include all USAF HH-60W aircraft.

1.7.1. Condition of Delivered Aircraft: The aircraft shall be returned to the customer in the same configuration as received, with the same type components, accessories, and special equipment installed except as modified, removed, or added by requirements of this DMSPEC or as directed by the USAF Engineering Authority (EA) and USAF Program Authority (PA). The depot facility shall ensure the finished helicopter is complete and neat in appearance. System condition and serviceability shall only be negotiated through the EA and PA prior to the aircraft being released from the depot facility to the gaining custodian. The HH-60W aircraft, although not required to be fully mission capable, shall be safely flyable, capable of flight from the depot facility to the post- DLM destination in Instrument Meteorological Conditions (IMC), and must meet all other minimum service specifications as required by the EA and this DMSPEC.

1.8. DLM Words and Terms: The following are words and terms that are generally applied across this DMSPEC to provide common meaning to words and terms that may be used interchangeably between other service documents.

Preparation for Induction (DMPSEC, Section 2)

Aircraft Induction (DMPSEC, Section 3)

Inspection (DMPSEC, Section 4)

Maintenance and Repair (DMPSEC, Section 5)

Preparation for Delivery (DMSPEC, Section 6)

Aircraft Delivery (DMSPEC, Section 7)

1.8.1. Shall, Should, May, and Will Compliance: The intended meaning of terms that specify compliance with procedures or requirements are as follows:

“Shall” has been used only when application of a procedure is mandatory.

“Should” has been used only when application of a procedure is recommended.

“May” and “need not” have been used only when application of a procedure is optional.

“Will” has been used only to indicate futurity; never to indicate any degree of requirement for application of a procedure.

1.8.2. Technical Data: For the purposes of this DMSPEC, technical data refers to approved USAF published T.O.s, maintenance manuals and/or other USAF approved data/information used by artisans and mechanics to inspect, maintain, and repair the aircraft. Use of any non-USAF technical data must be approved and documented by the USAF EA. Throughout this document use of the term "maintenance manuals" will mean USAF T.O.s.

1.8.3. Engineering Data: Engineering data refers to engineering drawings, specifications, standards, reports, and other engineering generated documentation to include but not limited to data that is used to define the proper configuration, operation, assembly, manufacture and/or steps and processes that serve as source data for technical data.

1.8.4. Engineering Technical Assistance Request (ETAR): A process used to request engineering technical assistance IAW AFMCMAN 63-1202 in the absence of published technical data to maintain or repair aircraft. In the absence of technical order or maintenance manual procedures or otherwise approved local procedures or processes to perform a task or a repair the depot facility shall utilize the ETAR process.

1.8.5. Flight Safety Critical Aircraft Part (FSCAP): An FSCAP is an item, assembly, or installation procedure with one or more critical characteristic that, if not conforming to design data or quality requirements, would result in serious damage to the aircraft or serious injury to personnel. Critical characteristics may be identified as dimensions, tolerances, finishes, materials, assembly, or inspection procedures. As defined by this DMSPEC and listed in paragraph 9.5 of this DMSPEC, FSCAPs include those items managed by the following programs:

• Flight Safety Critical Aircraft Part (FSCAP)

• Flight Safety Part (FSP)

• Critical Safety Item (CSI)

• Critical Application Item (CAI)

• Safety Critical Screw-Threaded Component (SCSTC)

1.9. DLM Defect Classification Criteria: A fundamental task associated with the DLM process includes objectively classifying defects in order to determine if a defect requires correction. Defect classification determines whether a defect shall be corrected or not. The following paragraphs outline the methods for classifying defects discovered during the rework process to determine if the defects require maintenance under the DLM program and to establish a general level of expectation as to the quality of repair. A defect classification decision tree is provided in Figure 2 Defect Classifications.

The classification criteria for each class of defect is as follows:

1.9.1. Corrosion Defects: All corrosion shall be removed, cleaned, evaluated, and measured for determination of repair actions IAW the applicable maintenance manuals. Bare metal shall then be treated as applicable IAW maintenance manuals.

1.9.2. Critical Defects: A critical defect is a defect that is likely to result in hazardous or unsafe conditions for individuals operating or maintaining the aircraft, system, or component. All critical defects discovered as a direct result of, or incidental to, compliance with the DLM requirements shall be corrected.

1.9.3. Major Defects: A major defect is a defect other than critical that is likely to result in failure, or to materially reduce the usability of an aircraft system or component from its intended purpose. All primary airframe structural cracks shall be classified as major defects at a minimum and evaluated IAW the applicable maintenance manuals. Major defects discovered as a direct result of, or incidental to, compliance with the DLM requirements that require depot-level maintenance and/or affect minimum mission equipment required for delivery of the aircraft shall be corrected. Major defects shall consist of depot-level discrepancies that cannot be, or are not practical to be, accomplished at O/I-level by the owning activity.

1.9.4. Minor Defects: A minor defect exceeds negligible limits but is not likely to materially reduce the usability of a system or component for its intended purpose. Minor defects shall be addressed IAW paragraph 1.12 of this DMSPEC. Minor defects shall consist of “economy tasks” that are economically practical to perform at the depot facility due to the disassembly of the aircraft during the DLM process.

1.9.5. Defects Caused by Depot Facility: All defects caused by the depot facility shall be corrected at no cost to the customer.

Figure 2. Defect Classifications

1.10. Acceptance and Rejection Criteria: The EA and/or the PA shall determine whether defects have been corrected satisfactorily, and that applicable maintenance standards have been met with respect to materials, workmanship, design, construction, cleanliness, quality, and documentation.

The EA shall have final approval on determining if the aircraft has been delivered in acceptable condition and that all applicable quality control standards have been met.

1.11. Use of Technical Data: For the purpose of this DMSPEC, use of approved and published USAF T.O.s and technical manuals is mandatory. Use of other technical data to include but not limited to US Army, US Navy or other sources of technical data and technical manuals or locally generated technical data will require formal written approval from the EA. In the event that there is conflicting information in this DMSPEC and any technical data, the DMSPEC takes precedence unless otherwise authorized and documented by the EA. Throughout this DMSPEC, the 1H- 60(H)W-2, and the 1H-60(H)W-3 will be the primary technical data used to perform the DLM tasks but not always listed with the task description in this document. The general maintenance manuals as listed in Table 4 List of Applicable Publications will be secondary.

1.12. Required DLM Tasks: This paragraph contains maintenance requirements and related references applicable to the DLM process. The DLM work tasks shall consist of a thorough and comprehensive inspection of the aircraft structure, and repair of identified defects.

1.12.1. Clean, Strip, Paint, and Finish: All aircraft undergoing the scheduled DLM rework process shall undergo clean, strip, paint, and finish of the exterior airframe surfaces and touch up of interior fuselage surfaces, covers, access panels and floor panels.

1.12.2. Authorized Depot-Level Maintenance Tasks: The depot facility shall inspect for and repair defects requiring depot-level maintenance. These defects, IAW paragraph 1.9 and Figure 2 of this DMSPEC, include the following:

1.12.3. Authorized Organizational / Intermediate-Level (O/I-Level) Maintenance Tasks: Except as specified by this DMSPEC, the depot facility is not generally authorized to perform any inspection or repair that can be accomplished by O/I-level maintenance at the owning activity.

However, inspection and repair under the following circumstances shall be accomplished without prior approval from the EA and/or PA.

• O/I-level time change items that will exceed the specified replacement interval prior to the aircraft’s first 120-hour inspection after completion of the aircraft functional check flight and ferry flight to the post-DLM destination.

• Inspection and repair of defects that cannot be accomplished by the owning activity.

• Maintenance action beyond the capability of the O/I-level owning activity.

• Defects in those areas not normally accessible during O/I-level owning activity inspections (i.e., fuel cell area, under cabin/cockpit floors, nose shelf, etc.).

• Inspection and repairs that can be performed by the depot facility concurrently and economically during the DLM rework process.

• Special work requested on a USAF PA signed and approved AFTO Form 103.

• Critical defects or defects that affect flight safety.

• Concurrent repair, overhaul, refurbishment, or rework of aircraft parts, avionics, or components that do not affect the airworthiness or operation of the aircraft.

• Defects that can be best economically repaired by the O/I-level owning activity.

1.12.5. Calendar / Scheduled Inspections and Maintenance: The depot facility shall accomplish all maintenance and expired calendar, scheduled, or time/fatigue life-limited inspections IAW the applicable aircraft and component periodic maintenance manuals. All required aircraft and engine logbook entries shall be completed by the depot facility prior to delivery of the aircraft to the gaining custodian. Calendar inspections and maintenance tasks that come due during the DLM process, or within 3 months after delivery of the aircraft to the post-DLM destination, shall be completed by the depot facility prior to delivery of the aircraft to the gaining custodian but may be postponed until reassembly of the aircraft as applicable. Follow on fastener torque check requirements shall be accomplished prior to the aircraft ferry flight home.

1.12.6. Time Change Items: Remove and replace/repair any O/I-level time/fatigue life-limited component that will exceed the specified replacement interval prior to the aircraft’s first 120-hour inspection after completion of the aircraft functional check flight and ferry flight to the post-DLM destination.

1.12.7. Daily and Turnaround Inspections: The depot facility shall be responsible for the accomplishment of all daily and turnaround inspections to prepare the aircraft for all flights required to complete the DLM process, including the post-rework FCF.

Sikorsky Ground Based Application (SGBA) shall be reviewed, and all discrepancies reconciled. Aircraft data shall be uploaded by the depot facility IAW 1H-60(H)W-2.

1.12.8. Phase Inspections: All phase inspections shall be completed IAW Section 4 of this DMSPEC. All inspections shall be conducted concurrently as applicable.

1.12.9. Time Compliance Technical Orders (TCTO): Depot-level or O/I-level TCTOs that consist of both technical modifications and/or inspections may be required during the DLM process on an O&A basis when approved by the USAF PA via AFTO Form 103 submission. Guidelines for incorporating TCTOs issued prior to or during the DLM process are provided in the below paragraphs 1.12.9.1 through 1.12.9.4.

1.12.9.1 Inspection TCTOs: The depot facility shall accomplish the following technical inspection TCTOs when approved by the USAF PA via AFTO Form 103 submission.

• O/I-level inspection TCTOs.

• Depot-level inspection TCTOs.

• Airframe, structural, or corrosion inspection TCTOs regardless of maintenance level.

• Inspection TCTOs to achieve required mission capability of the delivered aircraft.

• Inspection TCTOs that can be performed concurrently and economically during the rework process.

NOTE

Immediate Action, Urgent Action, Safety Inspection, Routine Safety and Flight Safety TCTOs, when issued after the aircraft induction / during the DLM process, shall be accomplished by the depot facility automatically, without submission of an AFTO Form 103.

1.12.9.2 Modification TCTOs: The depot facility shall accomplish routine technical modification TCTOs when approved by the USAF PA via AFTO form 103 submission. All urgent or flight safety TCTOs issued after the aircraft induction / during the DLM process, shall be accomplished without submission of an AFTO Form 103 as noted above.

1.12.9.3 Modification Kits: The depot facility shall maintain integrity of modification kits. No part shall be robbed from a kit without written concurrence from the USAF PA.

1.12.9.4 Technical Inspection / Modification Logs and Records: The depot facility shall ensure that all technical inspection/modification TCTOs that are accomplished during the DLM process are properly recorded in the aircraft logs, records, forms, and historical documents as required by the applicable maintenance manuals.

1.12.10. Over and Above (O&A) Maintenance: Only maintenance tasks accomplished solely as part of the USAF PA signed and approved AFTO Form 103, and not negotiated as part of the aircraft work package IAW the DMSOW and this DMSPEC, will be considered O&A maintenance.

All O&A maintenance must be approved by the PA.

1.12.11. Noted But Not Corrected (NBNC) Defects: O/I-level defects not authorized to be corrected, or any defects that have been approved for non-correction by the EA and/or PA, shall be identified by type, location, and description on the NBNC Report for appropriate action by the gaining custodian IAW the DMSOW.

1.12.12. Nonstandard Repairs: Any nonstandard temporary repair discovered during the DLM process and/or any previous repair that is not authorized by, or does not meet the standards of quality, security, or strength of the applicable maintenance manuals, or that has not been approved as a permanent repair via ETAR submitted by the owning activity and signed by the USAF EA, shall be considered a defect. The depot facility shall submit an ETAR for USAF EA evaluation and disposition IAW paragraph 5.1.1 of this DMSPEC and the DMSOW user access instructions.

1.12.13. Nonstandard Modifications: Any airframe or structural modification that was intended to be temporary or was part of a modification program that was never made permanent and that is discovered during the DLM process, shall not automatically be considered a defect. The depot facility shall review the aircraft records for details and if necessary, shall submit an ETAR for USAF EA evaluation and disposition.

1.12.14. Disturbed Systems: Systems including but not limited to electrical, hydraulic, and fuel systems that were disturbed during the DLM process such that the complete system installation, function, and operation cannot be assured shall receive an operational check IAW the applicable maintenance manuals prior to aircraft delivery to the gaining custodian. Removal and replacement of electronic boxes and disconnecting cannon plugs to facilitate maintenance does constitute disturbing the system.

1.12.15. Engine Maintenance: HH-60W aircraft that are flown in for induction at the depot facility under this DLM concept, and IAW this DMSPEC, shall have operational engines. Engines that fail during the receiving inspection, the PDM or ACI inspections, or during FCF (low power, etc.), and are determined to be beyond approved/economical repair, shall be replaced. If an engine is determined to be unserviceable and/or unrepairable by the depot facility, a replacement shall be provided by the owning activity.
