STAR codes are two-digit numeric codes used to describe or give reasons for transactions such as strikes, transfers, acquisitions, or removals of aircraft engines. They are also used-to identify end-of-quarter reports of hours flown and reports of completion of complete repairs, etc. A status code is often used without a STAR code, but a STAR code is never used without a status code. A STAR code amplifies or qualifies the status code.

STAR codes are divided into the following five series:

50 series - Acquisitions

60 series - Transfers and receipts

70 series - Removals

80 series - Strikes

90 series - Miscellaneous

The various STAR codes are explained in detail in NAVAIRINST 13700.15.

Data elements are used to identify the items of engine data submitted in the required reports. These data elements are used in all engine management reports to describe the items of information that are being transmitted. You should refer to NAVAIRINST 13700,15 for a listing and explanation of the data elements.

Some controlling custodians have assigned additional data elements for use by their reporting custodians. These data elements are used to furnish the controlling custodian additional required information. In COMNAVAIRLANT and COMNAVAIRPAC activities, data element 0 is used to report the transaction serial number. Certain of these data elements must be listed on every engine transaction report (ETR); others are used only in specified and seldom occurring transactions. The appropriate controlling custodians instruction concerning engine management explains the proper use of data elements.

RECORDS AND REPORTS

There is one record and two reports used in the aircraft engine management system. These reports are made either by naval message or on a form, depending upon the appropriate controlling custodian’s instructions. Regardless of the method of reporting, all engine reporting custodians report approximately the same engine data.

The Aircraft Engine Record is a 5 x 8 record card designed to provide a standardized record for local management of aircraft engines. It is used in much the same way as the aircraft record A card is used in aircraft inventory reporting. One engine card is maintained on each assigned engine. Whenever reportable actions occur, an ETR is submitted, and certain items of information are
