Introduction:
Aircraft structure teardown inspection and evaluation programs are conducted on
durability test specimens and retired aircraft to discover, characterize and thoroughly
document structural damage that was not detected via other methods. In this context,
they are destructive inspections as opposed to disassembly to enable inspections. The
data obtained from these efforts are used in the durability, damage tolerance, and risk
