Q15. Q16. Ql7. What publication contains detailed information on aircraft historical files? How long must aircraft inspection documents be maintained on file? A completed VIDS/MAF requesting "local manufacture of drip pans" would be maintained in what historical file? completion. This file should include all aircraft and engine-related MAFs. TD Compliance File. This file will be maintained by BUNO for a minimum of 6 months from the completed date. Miscellaneous File. This file will contain all non-BUNO MAFs and may be separated by Type Equipment code, serial number, or job control number (JCN) at the commands discretion. Aircrewman’s Flight Equipment File. Each aircrewman has a separate file containing the Aircrew Personal Equipment Record and Aircrew Systems Records. Copy 1 of completed MAFs on all maintenance performed on this equipment is retained for 6 months. SUBSYSTEM CAPABILITY AND IMPACT REPORTING (SCIR) LEARNING OBJECTIVE: Describe Subsystem Capability Impact Reporting and its purpose. Subsystem Capability and Impact Reporting reports show an equipment’s mission capability. These reports are generated from Equipment Operational Capability (EOC) codes placed on the VIDS/MAF or in NALCOMIS. SCIR provides factual information, generated at the lowest level of maintenance, as to aircraft or equipment inventory and actual subsystem performance. It provides specific aircraft or equipment mission capability and uniquely defines the categories of full mission capable, partial capable, and not mission capable for a specific type and model aircraft or equipment. EOC codes are documented when a specific system or subsystem is degraded and impacts the mission capability of that equipment or aircraft. The EOC code is a three-position code. The first position is derived from the Mission Essential Subsystem Matrices (MESM), published as an enclosure to OPNAVINST 5442.4. The last two positions are computer generated as determined by the documented Work Unit Code. Only the first position is entered on the MAF or in NALCOMIS. For more information on EOC codes and levels of aircraft or equipment mission capability, refer to OPNAVINST 5442.4. More information on SCIR reports can be obtained in Vol III of OPNAVINST 4790.2. Q18. Equipment Operational Capability (EOC) codes are used on VIDS/MAFs or in NALCOMIS to generate what reports? Q19. The Mission Essential Subsystem Matrices (MESM) is used to select what position of the EOC code that is entered on the MAF? Q20. How are the second and third positions of the EOC code determined? AIRCRAFT LOGBOOKS LEARNING OBJECTIVE: Recognize the different sections of the aircraft logbook and their purpose. The aircraft logbook is a hard-cover, loose-leaf, ring binder that contains separators and page insert forms. Since the logbook contains loose-leaf forms, it is imperative that the model and bureau number be on both sides of each page in the spaces provided to ensure positive identification when pages are removed or new continuing pages are initiated. Each form is for recording specific information about the aircraft. The maintenance control office keeps the logbook in its spaces, and an AZ normally makes the entries. As a maintenance supervisor, you should be familiar with the information required in the aircraft logbook. Each aircraft logbook has a record of rework, major repairs, and flight and operational data. Also included in the logbook, in the appropriate sections, is a record of maintenance directives affecting the aircraft, its components, and accessories. Figure 7-2 shows aircraft logbook construction and sequence. Upon acceptance of a new naval aircraft, the original accepting activity will initiate the logbook and ensure the number of flights and flight hours since new are logged, including the hours flown by the manufacturer. The aircraft logbook is maintained by the reporting or physical custodian. For aircraft supported under contractor maintenance, the onsite support center liaison officer will ensure verification of the logbook or records required. The following text provides a brief description of the sections in the aircraft logbook. Refer to 7-5
