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
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
Aircrewmans 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 equipments 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.
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?
How are the second and third positions of the
EOC code determined?
LEARNING OBJECTIVE: Recognize the
different sections of the aircraft logbook and
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
