record acceptance information, custody and transfer, record of rework, preservation and depreservation, and TDs. Also, it contains a record of periodic maintenance performed by hours, starts, date completed, next PM due, activity, and signature. It accompanies all items of SE that have MRCs, MIMs, an HSI, a manufacturer's handbook, or periodic maintenance requirements as directed by TDs. Exceptions are precision measuring equipment (PME), engine test cells or stands, and oxygen-nitrogen generating plants (GB-1As), as these items have their own records. Reporting custodians retain the latest completed copy and current copy of the record, and they transcribe the accumulated data upon initiation of each new record.

SE TRANSACTION REPORT (TR)

The SE Transaction Report (OPNAV 4790/64) is used to record SE issue and receipt transactions, Figure 4-44 shows the TR card with an explanation of the various entries for the activity submitting the report.

When issuing SE on a subcustody basis, the TR is signed by the user in block A. The white, green, and yellow copies of the TR are retained by the issuing activity for local recordkeeping purposes. The pink copy is retained by the using activity for its records.

When returning SE to the reporting custodian (usually the IMA), block B of the TR is signed by receiving personnel.

All of the discrepancies noted during issue, receipt, or preoperational inspections are annotated on a VIDS/MAF by IMA production control.

HISTORICAL FILES

The completed and processed copy 1 of the VIDS/MAF is retained by maintenance control for a minimum of 6 months from the completed date (block B30). The historical file requirements are described in the following paragraphs.

AIRCRAFT INSPECTION FILES

The aircraft inspection file is maintained for each BUNO. It should be arranged to group the control, look, and fix-phase documents for a given inspection. Documents in support of a phase or special inspection are retained for one complete inspection cycle or 6 months, whichever is greater. Calendar inspection documents are retained for the last two completed calendar inspections. Conditional inspection documents are maintained in this file for 6 months from the completion date.

AIRCRAFT GENERAL FILES

The aircraft general file is maintained by BUNO in JCN sequence. It is grouped by month of completion (block B30 on the VIDS/MAF). Individual units have the option of establishing local files by work center as long as the above filing order is maintained. All other aircraft and engine VIDS/MAFs are contained in this file. Filing VIDWMAFs with an action taken code of N is optional.

TD COMPLIANCE FILE

The TD compliance file is maintained by BUNO for a minimum of 6 months from the completed date, as shown in block B30 of the VIDS/MAF.

NOTE: Upon transfer of the aircraft, the aircraft inspection, TD compliance, and general files are forwarded with the aircraft.

MISCELLANEOUS FILES Miscellaneous files contain all non-BUNO VIDS/MAFs. They may be separated by TEC, serial number, or JCN as desired by the local command.

THE MONTHLY MAINTENANCE PLAN

The purpose and contents of the organizational and intermediate maintenance activities' monthly maintenance plans are discussed in the following paragraphs.

ORGANIZATIONAL-LEVEL MONTHLY MAINTENANCE PLAN

The purpose of the monthly maintenance plan is to provide scheduled control of the predictable maintenance workload. This workload might include inspections, transfer and/or receipt of aircraft, and incorporation of technical directives. By scheduling the predictable maintenance, the capability for accomplishing unscheduled work can be determined. Additionally, requirements for
