ACCEPTANCE INSPECTIONAn inspection
performed at the time a reporting custodian accepts
a newly assigned aircraft, from any source, and on
return of an aircraft from SDLM or other major
D-level rework. It includes an inventory of all
equipment listed in the AIR, verification of CADs
and AEPSs, a configuration verification, hydraulic
fluid sampling, a daily inspection, and a complete
FCF. For acceptance inspection purposes,
verification of CADs, AEPSs, and configuration is
accomplished by visual external inspection and
record examination only. Disassembly beyond the
daily inspection requirements of applicable PMS
publications is not required. The accuracy of flight
hours on the Monthly Flight Summary (OPNAV
4790/2 IA) is verified by checking the PERIOD
and SINCE NEW blocks and operating hours on
the Equipment Operating Record (OPNAV 4790/3
IA) in the ACCUM block. Activities may elect to
increase the depth of the inspection if equipment
condition, visual external inspection, or record
examination indicates such action is warranted.
