Data block GG must contain the name, rank, and signature of the person authorized to approve the transfer. Activities may include other information on the document when transferring aviation depot-level repairable (AVDLR) material. This information may include the job control number (JCN), part number, serial number, and family group code. Refer to NAVSUP P-545 or NAVSUP P485, chapter 5, for the procedures in transferring depot-level repairable (DLR) items. When the transferring ship uses DD Form 1348-1 to document the transfer, distribute copies as described in the following texts. Refer to AVDLR procedures for distributing copies of repairable shipment documents. The original copy stays with the transferring ship, and is filed in the expenditure invoice file after posting. Copies 2 and 3 are attached to the material and sent to the requesting ship. Copy 4 stays with the transferring ship, and is attached to–the retained copy of the summary; or it is discarded if applicable to APA material. Copy 5 stays with the transferring ship to support the summary; or it is discarded if applicable to APA material. Copy 6 is attached to the original copy in the expenditure invoice file of the transferring ship after the receipt signature is obtained. The transferring ship may discard this copy if receipt signature is not requested. Transfer of Aviation Fuel Transfer of aviation fuels and lubricants between ships with AVCAL accounts use DD Form 1348 to document the transaction. The document must cite the special Accounting Class 207 NSA fund code. The SUADPS system will treat the transfer as an Other Supply Officer (OSO) transaction. Transfers from ships with AVCAL accounts to ships without AVCAL accounts can be documented on DD Forms 1149, 1348, or 1348-1. Transfer of aviation fuel to shore activities (offload) is documented on an unpriced DD Form 1149. The transaction is not summarized but must be reported according to NAVSO P-3013-2, paragraph 6105. Transfer of Special Clothing Transfer of special clothing to other ships needs approval from the commanding officer. Ships can transfer special clothing to a shore activity only when the on-hand quantity is in excess of the authorized allowance. The documentation used for transferring special clothing is DD Form 1348-1. Transfer of Aircraft Engines Transfer of aircraft engines from the custody of a reporting custodian to another activity requires submitting a report. See procedures described in NAVAIRINST 13700.15 (series). The Aircraft Engine Management System (AEMS) allows the use of an on-line computer terminal for submitting reports on aircraft engines. The AEMS terminal also allows retrieval of information on specific engines. AEMS provides accurate and timely data to Naval Air Systems Command (NAVAIR) and air type commanders. The document used for shipping aircraft engines is DD Form 1348-1. With MILSTRIP data, the document also must include the type, model, serial number, and condition of the engine. SURVEYS The term survey refers to the procedures for determining the cause of gains, losses, or damage to government property. Also, it determines the procedure for establishing personal responsibility (if any) and documenting necessary inventory adjustments to stock records. The form used for survey is the Financial Liability Investigation of Property Loss, DD Form 200. The purpose of the form is to report the facts and circumstances supporting the assessment of financial charges for the loss, damage, or destruction of DOD-controlled property. Even with the physical security and quality control established by activities to take care of government property, discrepancies occur. The discrepancy may be between stock or property book balances and the physical status of material in storage. The discrepancies are subject to review/approval thresholds, as described by their applicable category. The categories are supply system stock or property book material. The NAVSUPINST 4440.115 (series) provides procedures for processing the DD Form 200. All items with discrepancies are subject to survey report procedures. The only exception is incoming shipments that can be attributed to shipper or carrier 7-15
