Standard Depot Level Maintenance (SDLM) restores an aircraft to a condition, which can be maintained at the organizational maintenance level. SDLM consists of a thorough inspection of aircraft structures, systems and components, with depot level repair, preventive maintenance and modification, as necessary. Individual aircraft model SDLM specifications can be obtained from the Cognizant Field Activity (CFA). Aircraft going to SDLM require a "Special Work Request" to be submitted 30 days prior to the scheduled induction date, if additional maintenance other than that specified in the SDLM specification is desired. The Special Work Request is defined in COMNAVAIRFORINST 4790.2, Volume II, Chapter 6

XRAY reports provide input data for the aircraft inventory reporting system. XRAY reports are submitted upon receipt have and depot level maintenance actions on aircraft. In addition, OPNAVINST 5442.2G lists the other occasions requiring submission of OPNAV XRAY reports and procedures to be followed.

ETRs are submitted any time the status of an engine or module, either installed or uninstalled, changes and when an engine or module is transferred from one custodian to another. NAVAIRINST 13700.15D contains ETR submission requirements.

Verify Weight and Balance data are current upon completion of Scheduled Depot Level Maintenance (SDLM), upon receipt and transfer of aircraft, and every 90 days. Aircraft logs and records must show documentation change of weight and balance when equipment is deleted or added to the aircraft inventory

The purpose of the pre-expended bin (PEB) is to simplify the issue and accounting procedures for maintenance related materials.

1) Material Control Officers are responsible for flight packets issued to pilots for extended flights. The flight packets should include the necessary forms or documents required to procure material or services necessary to continue a flight, and the instructions on how to use these documents.(2) Flight packets are required to be inventoried and signed by the pilot in command at each checkout and upon return. If not used, they shall be inventoried monthly by the Supply Officer or Material Control Officer.

Pack-up kits are provided for use by operating squadrons, on detachment in areas where normal supply support is limited. The pack-up kits normally consist of high usage repairable and consumable item

1) An OPTAR provides funds required by an activity to perform its mission. The Aviation Maintenance Manager should be familiar with the types of OPTAR’s granted and their purposes, the basic accounting concept used, and the required records and reports. Items covered, reporting, and record keeping procedures are explained in the NAVSO P3013-1. The Material Control Officer provides the maintenance department tracking for the following OPTAR funds:(a) OFC-01, Flight Operations(b) OFC-50, Aviation Fleet Maintenance, Materials and Service

Aircraft Inspections conducted by flight crews or maintenance personnel are: Daily, Turnaround, Conditional, Special, Calendar and Phased Maintenance Inspections.

(1) The ASPA program provides an assessment of the overall general material condition of an aircraft. The objective is to determine if the aircraft can remain in service through a 12 month Period End Date (PED) adjustment.(2) ASPA inspections may be conducted within six months prior to the PED of an aircraft or up to 90 days after the PED.(3) ASPA inspections will be requested by the reporting custodian utilizing P & E request.(4) X-ray reports are required per OPNAVINST 5442.2G.(5) The Type Commander in conjunction with the Type Wing will make the final decision as to whether the aircraft passes or fails ASPA based on the P& E inspector's report.

(1) The aircraft log book for each aircraft contains records of flight and operational data, technical directive compliance, inspections (where required) and major rework performed. It also contains records of installed explosive devices and scheduled removal components. It is maintained by the logs and records section of maintenance control.(2) The logbook may only be signed by the Commanding Officer, O-level Maintenance Officer, I-level Maintenance Officer, D-level Director of Operations and OMD Officer. Other personnel designated in writing by any of the previously stated individuals may also sign the aircraft logbook.

The AESR is maintained in a manner similar to the aircraft log book. Full identification data and serial number are inserted on both sides of each page in the spaces provided to ensure ready identification. The AESR accompanies the equipment at all times.

The Record "A" Card is maintained for each squadron aircraft. It provides audit data on each XRAY transaction and accumulated monthly flight time.

(1) The AIRS is used at various levels of management to maintain operational commitments, rework schedules, and for budgeting purposes. The data required for the AIRS is as follows:(a) XRAY Reports(b) Aircraft Accounting Audit Report(c) 3M Flight Data Forms(d) Visual Inspection Display System/Maintenance Action Form (VIDS/MAF)(e) Inventory Gains and Losses(f) In/Out of Material Condition Reportable Status (MCRS)

This inspection is a general inspection of a specific area of an aircraft. These inspections are for obvious defects such as leaks, frayed cables, cracks, corrosion, or physical damage. Zonal inspections are normally performed in conjunction with other scheduled maintenance tasks by the rating or MOS assigned. For example, an AT rating or MOS assigned to perform an inspection on a radar antenna may also be assigned a zonal inspection of the compartment for obvious defects.
