CHAPTER  8 AERONAUTICAL EQUIPMENT SERVICE RECORD (AESR) Aircraft  maintenance  activities  are  also  tasked  with the responsibility of maintaining aeronautical equip- ment service record (AESR). Currently, organizational and intermediate level maintenance activities maintain AESRs in paper format as well as electronic format found in the Naval Aviation Logistics Command Management Information System (NALCOMIS). AERONAUTICAL EQUIPMENT SERVICE RECORD (AESR) DESCRIPTION LEARNING  OBJECTIVE:  Define  the  pur- pose of the Aeronautical Equipment Service Record (AESR). The  Aeronautical  Equipment  Service  Record (AESR)  is  the  log  used  to  maintain  records  on aeronautical equipment that are an integral part of the aircraft. The AESR is a loose-leaf log that is contained within a separate cover. The log can be inserted in the aircraft logbook binder, or the log may stand alone. The AESR is maintained in much the same manner as the aircraft logbook. Many of the records used in the aircraft logbook are also used in the AESR. In this chapter, we will discuss records common to the aircraft logbook and AESR, but we will focus more on records unique to the AESR. ORIGIN LEARNING  OBJECTIVE:  Identify  the activity that originates AESRs. The AESR is initiated by the activity that originally accepted the equipment for the Navy, and the AESR is subsequently  maintained  by  the  activity  that  has custody  of  the  equipment.  When  equipment  is installed as part of the aircraft, the AESR is maintained concurrently with the aircraft logbook, and the record becomes a part of the logbook. Q1. What log is used to maintain records on the aeronautical equipment that is an integral part of an  aircraft? Q2. What activity initiates the AESR? APPLICATION LEARNING OBJECTIVE: Identify equip- ment that requires an AESR. An AESR is required for each of the specific equipments listed below: Aircraft power plants (engines) Auxiliary power unit (APU) Airborne gun pods Low-level escape system Propeller assembly In-flight refueling store/package AN/ALQ-99  pod Aeronautical  Expeditionary  Airfield  M-11, M-22, M-23, V-1, V-7, and L series lighting systems Gas Turbine Power Plant (7LM 1500 PB-104) Engine test cell/stand MK-105 magnetic minesweeping gear Support equipment gas turbine engines (GTEs) NOTE:   Each   aircraft   has   specific   AESR equipment  requirements.  The  periodic  maintenance information card (PMIC) deck for the specific type, model,  and  series  of  equipment  contains  AESR equipment requirements. In case of loss, damage, or destruction   of   an   AESR,   follow   the   same   re- construction procedures as those used for an aircraft logbook. MAINTAINING THE AESR LEARNING OBJECTIVE: Describe the disposition procedures for AESR data that has no designated place in the AESR. The AESR is maintained similarly to the aircraft logbook. Since the AESR is in loose-leaf form, the full 8-1
