CHAPTER 6 AIRCRAFT LOGBOOKS

CHAPTER 6 AIRCRAFT LOGBOOKS All activities that have reporting custody of naval aircraft and related aeronautical equipment and components maintain aircraft logbooks, records, and associated forms in an up-to-date condition. In addition, commands utilitizing Naval Aviation Logistics Command Management Information System (NALCOMIS) must also maintain an applicable logs and records subsystem in a proper and up-to-date status. AIRCRAFT LOGBOOK ROLE LEARNING OBJECTIVES: Define the purpose of the aircraft logbook. Identify procedures to correct erroneous aircraft logbook entries. Aircraft logbooks, records, and forms provide a complete history of aircraft inspections, flight hours or hours of operation, modifications, and major repairs. These records provide maintenance personnel with a source of information for scheduling future periodic inspections and component replacement. In addition, these logs, records, and forms, when maintained properly, provide management with information related to the aircraft’s and equipment’s service age. Incomplete or poorly maintained records can result in unnecessary inspections and overhaul of aeronautical components, even loss of aircraft and pilot or aircrew. Obvious mistakes in record keeping may be corrected by the current custodian and initialed or signed off without further reference to the previous custodian. Discrepancies that require corrective action should be researched immediately by the current custodian. The discrepancies should be corrected after receipt of correspondence from the previous custodian that specifies the appropriate corrective action. As you can see, properly maintained aircraft logbooks and records provide a critical function in aviation maintenance and aircrew safety. As an AZ assigned to the logs and records section of maintenance control, you will be responsible for maintaining logbook accuracy. To effectively perform as logbook clerk, you should have an in-depth working knowledge of the technical directive (TD) compliance system, naval correspondence formats, classified material handling, technical manuals and directives, and the NALCOMIS Organizational Maintenance Activity (OMA) Logs and Records subsystem. A complete listing of the responsibilities of the aircraft logbook clerk can be found in The Naval Aviation Maintenance Program (NAMP), OPNAVINST 4790.2. Q1. What record provides a complete history of air- craft inspections, flight hours flown, modifica- tions, and major aircraft repairs? Q2. What activity may make corrections to obvious errors in aircraft logbook record keeping. AIRCRAFT LOGBOOK DESCRIPTION LEARNING OBJECTIVES: Identify the activity that originates the aircraft logbook. Identify who maintains custody of aircraft logbooks. The aircraft logbook is a hard-cover, loose-leaf ring binder that contains separators and page insert forms. The logbook contains data that is needed to monitor an aircraft’s operation throughout its service life. The logbook also contains historical data about the aircraft’s rework, major repairs, and flight operational data. In addition, the logbook contains a record of the TDs that affect the aircraft, its components, and its accessories. ORIGIN Aircraft logbooks are initiated by the activity that originally accepts the aircraft. The original accepting activity is defined as either the naval plant representative office (NAVPRO), if at a contractor’s plant, or a designated Navy representative at any other delivery point. Q3. When an aircraft is accepted into the Navy inventory, what organization initiates the aircraft logbook? CUSTODY The logbooks are kept in the maintenance control office of the station, ship, squadron, or detachment to 6-1
