This Air Force Pamphlet (AFPAM) complements Air Force Policy Directive (AFPD) 63-1/20-1,
Integrated Life Cycle Management and Department of the Air Force Instruction (DAFI) 63-
101/20-101, Integrated Life Cycle Management. This AFPAM provides non-directive processes
and procedures that complement the mandatory policies for implementing Air System
Development and Sustainment Engineering Processes and Procedures under DAFI 63-101/20-101.
This publication applies to all civilian employees and uniformed members of the Regular Air
Force, the Air Force Reserve, the Air National Guard, and those who are contractually obligated
to comply with Department of the Air Force publications. This AFPAM also supports Department
of Defense Directive (DoDD) 5000.01, The Defense Acquisition System and DoD Instruction
(DoDI) 5000.02, Operation of the Adaptive Acquisition Framework (collectively called the DoD
5000 acquisition series). Additional non-mandatory guidance on best practices, lessons learned,
and expectations are available in the Guidebooks for each functional area of acquisitions, all of
which can be found at https://aaf.dau.edu/guidebooks/. Mission, safety, performance, and
sustainability remain the standards of excellence for aircraft. Safety and the ability to perform its
mission are important priorities for an aircraft throughout its lifecycle. This requires modifications
to an aircraft to extend its service life and its ability to perform its mission safely. The guidance in
this document supports this process to ensure that all personnel working to support an aircraft have
current and accurate procedures regardless of where the aircraft is operating. This AFPAM
provides recommended processes, procedures, and best practices for four lines of effort that are
essential to Air Force aircraft development and sustaining engineering. To ensure standardization,
any organization supplementing this publication will send the implementing publication to
SAF/AQR for review and coordination before publishing. In accordance with DAFI 63-101/20-
101, this publication applies to all military and civilian AF personnel, including Air Force Reserve
