Table 6-4.-Permissible Action Code/Status Code Combinations
Item Gperiod number. The period number
completed. The period commences when the
represents the period in which the aircraft is
serving (or last served, if not currently operating).
The period number changes only when the aircraft
begins a new operating period following standard
rework or new production. The period number
is preceded by zeros, as necessary, to reflect a
three-digit number. For example, 003 indicates the
third operating period of an aircraft.
NOTE: For newly accepted aircraft (before
first delivery to operating) and aircraft in the
nonstandard service life categories (aircraft not
subject to period criteria, aircraft in bailed or
loaned status, or drone and experimental models),
the period number will be 000.
Item Hperiod end date (PED). (A PED
computation chart is given in table 6-5.) This
element of information is related to item G above
in that it represents the date at which the period
indicated in that item is scheduled to be (or was)
aircraft is first reported in status A following
acceptance or rework. The type of rework to
which an aircraft is subject has bearing when
computing the end date. When an aircraft is first
received into an operating command, it is assumed
that it will be returned to a depot activity for
rework at the end of a predetermined number of
calendar months. The PED is figured on that
The month in which an aircraft is received
from Naval Air Systems Command Fleet Support
(NASC FS) custody is counted as NO month
in regard to operating period. The month
in which an aircraft is predicted to return
to NASC FS custody is counted as 1 month.
For example, an aircraft with an operating
period of 24 months is received into an operating
command from NASC FS custody in July 1991.
The predicted period end date for this aircraft
is July 1993.
