OPNAVINST 4790.2 for additional information and
documentation requirements for each section.
STRUCTURAL LIFE LIMITS,
This form (fig. 7-3) in the aircraft logbook is
generated by the squadron and is used to monitor
structural life limited components designated for
depot replacement that do not require scheduled
removal component (SRC) or assembly service record
(ASR) documentation. In addition, this form provides
a means for documenting basic life limitations, such
as maximum flight hours, catapults, arrestments, and
landings. These items must be properly managed to
ensure safety and structural integrity throughout the
service life of the aircraft. Aircraft structural life
limitations are specified in the periodic maintenance
information cards (PMICs).
MONTHLY FLIGHT SUMMARY,
This form (fig. 7-4) is designed to permit the
monthly compilation of significant flight operational
data throughout the service life of an aircraft.
Reporting custodians are required to log all flight
hours monthly in chronological order.
This form (fig. 7-5) is used in the logbook and the
Aeronautical Equipment Service Record (AESR). It
provides a means of recording all scheduled and
conditional inspections performed on an aircraft
during each period and on equipment for which an
AESR is required.
Accurate inspection records prevent instances of
wasted effort because of improper entries by aircraft
and equipment custodians. Questionable or
incomplete records leave receiving activities no
alternative but to assume that previous inspection
requirements were not completed.
The Repair/Rework Record (fig. 7-6) is used in the
logbook and the AESR. It contains a complete record
