1.0 Description of Services

1.1 Objective(s): This Performance Work Statement (PWS) describes the services required to research, analyze, advise, and develop deliverables to advance related scientific and technical information (STI) through the application of knowledge and resources in achieving the requiring activity's mission requirements defined herein.

The objective of this PWS is to provide engineering services in support of the F-15 SPO objective of developing and executing F-15 improved landing gear OSS&E in accordance with

MIL-STD-1530, Aircraft Structural Integrity Program (ASIP) and MIL-STD-1798 Mechanical

Equipment and Subsystems Integrity Program (MECSIP).

This effort will result in the final delivery of four reports consisting of the final F-15 C/D and

E Fatigue Analysis Report, Safe Life Assessment Report and Risk Analysis and Mitigation

Report Update, the Final Findings and Recommendations Report, and the Risk Analysis and

Mitigation Report

1.2 Benefit to United States Air Force (USAF): This acquisition will benefit the United States

Air Force (USAF) by supporting the future needs in accomplishing this effort to sustain the existing systems and provide for their long term sustainability on the F-15E.

1.3 Background:

The F-15 LGIP is intended to develop and execute objectives for the F-15 landing gear in accordance with MIL-STD-1530, Aircraft Structural Integrity Program (ASIP) and MIL-STD-

1798 Mechanical Equipment and Subsystems Integrity Program (MECSIP). Air Force ASIP and

MECSIP requirements specify that structural and functional integrity be maintained for the life of the aircraft to ensure operational safety, suitability, and effectiveness (OSS&E) of the weapon system. This requires that the safe-life and service history of safety-of-flight and mission-critical landing gear parts are known and monitored. However, the critical landing gear structural parts and processes have not been efficiently tracked and monitored since the F-15 was introduced into service, resulting in aircraft flying with an unknown risk associated with the landing gear integrity. It is also possible that F-15 operational loads and fatigue spectrum have shifted over time, and the remaining safe-life of landing gear parts needs to be analyzed, again putting an unknown risk on the warfighter. The LGIP was undertaken to ensure OSS&E throughout the weapon system’s remaining life. Efforts have been completed to date for the LGIP are the

Probabilistic Age Assessment; Reliability, Availability, and Maintainability (RAM) Analysis;

and Fatigue Analysis with OEM assumed spectrum.
