Aircraft Model. The model designation is entered
in the first space at the top left of the card; for example,
A-7E, F-14B, or F/A-18A.
Bureau number (BUNO). Enter the six-digit
BUNO assigned to that particular aircraft. Each aircraft
is assigned a BUNO for identification and record
purposes. This number remains with the same aircraft
from acceptance by the Navy until the aircraft is retired
or stricken from the Navy inventory. The number is not
reused or reissued to another aircraft.
Received From and Transferred To. These two
blocks are self-explanatory. As long as the aircraft is in
the custody of the reporting custodian that maintains
the "A" card, only the Received From line is filled in.
When the aircraft is transferred, the Transferred To
line is completed, and the card is moved to the inactive
"A" card file for 12 months.
Permanent Unit Code (PUC). The second line at
the right side shows the present reporting custodian and
Permanent Unit Code.
The next group of blocks provides data about the
current aircraft operating service life.
NOTE: When a new aircraft is accepted, it is
known that the aircraft will go eventually to a depot
maintenance activity for rework. This occurs after the
aircraft has accumulated a predetermined number of
operating service months (as opposed to calendar
months) or flight hours (in some cases). This operating
interval is known as the operating period.
The period number is entered in the Period block.
When the aircraft returns to an operating status after
standard rework, it acquires a new period number. The
new period number may be transcribed from the
Monthly Flight Summary (MFS) form of the aircraft
The PED is inserted in the space labeled PED. The
PED can also be obtained from the MFS form, or
computed by using procedures outlined in
The OPSERMOS accumulated as of the PED is
entered in the space next to the PED. OPSERMOS
should be computed by using procedures outlined in
A corresponding section (Planning Factors for
Model for Period) is set aside to record operating serv-
ice period planning factors as they relate to the period.
The operating service period (OSP) is the
specified length of a period either defined as months or
flight hours. OSP, operating service life (OSL), and
utilization rates (if applicable) for specific aircraft can
be found in OPNAVINST 3110.11.
The OSL is the specified length, in months, that an
aircraft is programmed for total service with the Navy.
NOTE: The interval between PEDs is regulated by
the CNO and varies with different models of aircraft.
Period lengths may also be changed as data on service
experience accumulate. The data may indicate that a
given aircraft model is so well constructed that it can
operate for longer periods of time between SDLMs.
The opposite is also true, and period lengths may be
shortened as well. Aircraft are not operated after the
last day of the month of their PED unless specific
permission for an extension has been granted by higher
authority. Refer to the latest edition of OPNAVINST
3110.11 for more information on OSL, OPSERMOS,
and OSP for specific type/model/series aircraft.
The lower left portion of the front side of the "A"
card is used to record OPNAV XRAY reportable
actions submitted on an aircraft. OPNAV XRAY
reports that report change of location, fleet assignment,
or operational status of an aircraft are NEVER recorded
on the Aircraft Record A card. Reportable actions
should be posted to the card as they occur. The
following is a description of each block:
The OPNAV XRAY serial number is entered in
the first block. The OPNAV XRAY serial number is
the same serial number as the serial number of the
corresponding OPNAV XRAY report.
The Date of Action is next. The date must appear
exactly as it does in item "C" of the OPNAV XRAY
report, that is as a six-digit month, day, and year
The ACT block is a coded letter used to identify the
type of action reported. Remember, Action codes fall
into two separate categoriesAction codes that report
changes in custody and Action codes that report an ac-
tion other than change in custody. At any rate, the Ac-
tion code recorded here should match the same Action
code reported in the applicable OPNAV XRAY report.
The Status Code block contains the current aircraft
status and indicates the classification of the use or
condition of an aircraft.
The PED block reflects the current projected PED
of the aircraft.
The EXT block is used for recording an extension
to the present aircraft service period. Extensions are
