AIRCRAFT WEIGHT AND BALANCE RECORD SYSTEM LEARNING OBJECTIVE: Define the purpose of aircraft weight and balance program. The requirements, procedures, and responsibilities for weight and balance control of Navy aircraft are listed in USN Aircraft Weight and Balance Control, NAVAIR 01-1B-50. The Weight and Balance Data, NAVAIR 01-1B-40, is a technical manual that provides activities with a standard system of weight and balance control. A weight and balance handbook is maintained for each assigned aircraft. The handbook charts, forms, and records should be maintained in accordance with the instructions given in NAVAIR 01-1B-40 and NAVAIR 01-B-50. The weight and balance system reauires the use of the following charts and forms: Record of Weight and Balance, DD Form 365 Chart A, Basic Weight Checklist, DD Form 365-1 Form B, Airplane Weight Record, DD Form 365-2 Chart C, Basic Weight and Balance Record, DD Form 365-3 Chart E, load data, charts, graphs, and weighing procedures for an aircraft Form F, Weight and Balance Clearance, DD Form 365-4 All aircraft must be weighed upon completion of SDLM. Aircraft must also be weighed under each of the following conditions: When changes, modifications, or repairs are accomplished and calculated or actual weight and moment data for these changes are not available. When recorded weight and balance data are suspected of being in error. When unsatisfactory flight characteristics are reported by the pilot, and these characteristics cannot be traced to flight control system malfunction, improper aircraft loading, or errors in weight and balance data and computations. When weight and balance handbooks have been lost or damaged. (A new record must be promptly prepared.) When an aircraft has been painted. When an aircraft has not been weighed in five years. Q28. What is the purpose of the aircraft weight and balance system? SUMMARY The aircraft logbook provides a complete history of aircraft inspection, flight hours flown, modification, and major aircraft repairs. The current aircraft custodian may correct obvious errors in aircraft logbook record keeping without reference to the previous custodian. The original accepting activity initiates the aircraft logbook when its accepts an aircraft into the Navy inventory. In an organizational-level maintenance activity, the maintenance material control officer oversees the upkeep of the aircraft logbook and associated records. The logs and records for a destroyed aircraft are disposed of locally. The logs and records for an aircraft that is sold or transferred accompany the aircraft. When an aircraft is transferred, the ferry pilot provides flight time to the accepting activity. The logs and records for a special category aircraft that is removed from the Navy inventory are retained for 1 year and then forwarded to the Washington National Records Center. The Aeronautical Time Cycle Management Repository at Commander Naval Air Systems Command can provide information for the reconstruction of Assembly Service Records, Modular Service Records, and Scheduled Removal Component (SRC) cards. The maintenance officer of the station or unit to which an aircraft is assigned oversees aircraft logbook entries. Only specific personnel have the authority to sign aircraft logs and records. When there is no designated place for additional data in an aircraft logbook, the data is inserted in an envelope that is pasted inside the back of the logbook binder. Monthly flight operational data is recorded on the monthly Flight Summary record. Phase inspections are logged in the periodic inspection record. When a phase inspection is recorded on the inspection record, flight time and the type of phase inspection should be entered in the Type or Description of Inspection block. 6-37
