Pages or forms, other than those described in
the following paragraphs, are not inserted,
stapled, or attached to the AESR. Additional
data, for which there is not a designated place in
the logbook, and a copy of the most recent engine
setup or test record are placed in the manilla
envelope in the back of the AESR. Superseded

A brief description of the forms used in the
AESR is contained in the following paragraphs.
Aeronautical Equipment Service Record
(Cover) (OPNAV 4790/29)
The Aeronautical Equipment Service Record
(fig. 7-1) is the cover for the AESR. The
information on the front cover is entered as shown
in the figure by the activity initiating the record.
Subsequent entries are made by activities using
or operating the equipment. The inside of the
AESR cover contains general instructions for the
maintenance of the record.
The operating interval is the authorized time
between overhauls for the particular equipment.
When the AESR is used for engines, a locally
produced replacement interval/due sticker is
placed over this block. The data required for the
replacement interval is obtained by review of the
replacement interval data block on each assembly
service record (ASR) and module service record
(MSR). The lowest time recorded is written as the
replacement interval on the AESR. The replace-
ment due is completed by adding the lowest
interval time to the engine time. Entries are made
in pencil to allow for component changes at repair
or rework activities.
The block titled Engine or Propeller Position
No. is used to indicate the engine or propeller
position number (1, 2, 3, or 4) as installed on the
aircraft. This position indicator aids in placing
associated accessory and other supplemental
records in the correct equipment record.
