Table 6-4.-Permissible Action Code/Status Code Combinations
Item G - period 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 H - period 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 basis.
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.Continue Reading
