Subject: Structural Certification Plans for Changes with the Potential to Impact
Aircraft Structural Integrity

Purpose:
MIL-STD-1530 (Ref. 1) establishes the requirement for structural certification updates
during the aircraft force management execution phase. The purpose of this Structures
Bulletin (SB) is to establish a process for executing this requirement after initial
Airworthiness Certification is obtained from the Technical Airworthiness Authority in
accordance with AFPD 62-6 (Ref. 2).
Discussion:
AWB-1015 (Ref. 3) establishes the Airworthiness process for aircraft material and
process substitutions with the potential to impact aircraft structural integrity. AWB-1015
states to use EZ-SB-13-001 (Ref. 4) during the evaluation of these design and process
changes and characterizes the technical and programmatic risk for each change. All of
these aircraft design and process changes should be supported by a structural
certification plan (SCP). In addition, other changes with the potential to impact aircraft
structural integrity as described above should be supported by an SCP.
