MIL-STD-1530 Aircraft Structural Integrity Program AsipThis standard describes the USAF Aircraft Structural Integrity Program ASIP which defines the requirements necessary to achieve structural integrity in USAF aircraft while managing cost and schedule risks through a series of disciplined, time-phased tasks. It provides direction to government personnel and contractors engaged in the development, production, modification, acquisition, and/or sustainment of USAF aircraft.
