1. GENERAL INFORMATION AND INSTRUCTIONS

1.1. Program Description: This Depot Maintenance Statement of Work (DMSOW) provides an overview of the standard Depot Level Maintenance (DLM) rework requirements for the Air Force HH-60W model rotary aircraft. DLM is the accomplishment of depot-level rework of the HH-60W helicopter airframe and repair of defects to ensure safe operation of the aircraft during its operational life. This section contains general information for the depot facility to manage the HH-60W DLM process.

1.2. Scope: The DLM program includes Programmed Depot Maintenance (PDM) and Analytical Condition Inspection (ACI) aircraft inductions as defined below. Upon completion of the PDM and ACI DLM process, the 720-hour phase inspection requirement is satisfied. The PDM and ACI DLM rework process consists of disassembly of the aircraft to the maximum extent practical to conduct a nose-to-tail inspection of the entire airframe for condition and security with identification and correction of defects in accordance with (IAW) the attached Appendix A, HH-60W Depot Maintenance Work Specification (DMSPEC), HH-60W-24-010-001. The DLM process includes fixed and variable tasks IAW the DMSPEC paragraph 1.5. The DLM program also includes maintenance actions such as component-level rework or test, Time Compliance Technical Order (TCTO) modifications and special inspections, and Unscheduled Depot Level Maintenance (UDLM) drop-in inductions and the deployment of Depot Field Teams (DFT).

1.2.1. PDM is the inspection and correction of defects that require skills, equipment, or facilities not normally possessed by operating locations.

1.2.2. ACI is an in-depth condition inspection to uncover hidden defects that are not detectable through normal inspection programs. ACIs generate data for engineering and technical evaluation of the relative aircraft condition resulting from corrosion, overstress, wear, and other effects caused by aircraft age, operational usage and environmental exposure.

1.2.3. UDLM requirements may include but are not limited to:

• Battle damage repair

• Crash damage repair

• Damage to primary structural elements

• Maintenance induced damage

• Corrosion damage repair and parts replacement

• Hard landing assessments

• TCTO Modifications

1.2.4. Drop-in UDLM will be performed on aircraft or aircraft components received from the aircraft owning activity that require maintenance at a depth and skill level greater than that available at the Organizational/Intermediate (O/I)-level.

1.2.5. DFT UDLM will be performed at off-site owning activity field locations in cases where an HH-60W is not safe for flight. DFTs will be responsible for performing all maintenance related tasks as defined by the individual engineering statement of work disposition IAW T.O. 00-25-107 and Section 6 of this DMSOW.
