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 Superseded forms are closed out with the statement "No further entries this page." and a new form is initiated. The superseded form remains in the AESR.

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 replacement 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.

Equipment Operating Record (OPNAV 4790/31A)

The Equipment Operating Record (fig. 7-2) is intended for use with all aeronautical equipment
