TEC—Type Equipment Code—A four-character code used to identify the complete end item or category of equipment being worked on; for example, aircraft, engine, or SE. A complete listing of TECs may be found in the Aviation Type Equipment Code List A7210-01. TECHNICAL DATA—Data required for the accomplishment of logistics and engineering audiovisual presentation required to guide personnel in the performance of operating and support tasks. processes in support of the contract end item. It includes drawings, operating and maintenance instructions, provisioning information, specifications, inspection and test procedures, instruction cards and equipment placards, engineering and support analysis data, special purpose computer programs, and other forms of TECHNICAL MANUAL—A publication containing a description of equipment, weapons, or weapon system(s) with instructions for effective use. Included are one or more of the following sections: instructions covering initial preparation for use, operational instructions, modification instructions, maintenance instructions, parts lists or parts breakdown, and related technical information or procedures, exclusive of those of an administrative nature. TENANT—Any activity that will be aboard a ship or station for a period of time sufficient to require specific assignment of shop, hangar, crew, and equipment or line spaces. Activities may use a facility as an assigned tenant or as a joint tenant. Specific spaces may be assigned on a rotational, seasonal, occasional, or transient basis as appropriate. TEST—Subjecting an aircraft, airframe, engine, accessory, or item of equipage to prescribed conditions to determine if it will function per predetermined requirements. TIME/CYCLE PREFIX CODE—A one-character alphabetic code that identifies the type of time or cycle data recorded on the item. T/M—Type Maintenance Code—A one-character alpha or numeric code that describes the type of maintenance action being performed. TM—Technical Manual or Type Maintenance. T/M/S—Type/Model/Series. TMINS—Technical Manual Identification Numbering System. TMR—Total Mission Requirements.

TRANSACTION CODE—A two-character numeric code used to denote the type of data being reported and to indicate the record type to be produced. TRANSFER—The act of conveying reporting/ controlling custody of an aircraft/SE to another custodian. TRANSFER INSPECTION—An inspection per- formed at the time an aircraft changes physical or reporting custody. It includes an inventory of items listed in the AIR, verification of CADs and AEPSs, configuration verification, and a daily inspection. CAD, AEPS, and configuration verifications are performed by visual external inspection and record examination only. Disassembly beyond daily in- spection requirements of applicable PMS publica- tions is not required. Flight hours should be verified as correct on the Monthly Flight Summary (OPNAV 4790/21A) by checking the Period and Since New blocks. In addition, correct operating hours should be verified on the Equipment Operating Record (OPNAV 4790/31A) by checking the ACCUM block. Activities may elect to increase inspection depth if the aircraft material condition or record examination indicates such action is warranted. Aircraft transferred from a depot or commercial repair activity require hydraulic fluid sampling prior to transfer. TRANSFER INSPECTION (SE)—An inspection performed at the time a reporting custodian trans- fers an item of SE on a permanent basis. It includes an inventory of all records and components that make up the item of SE, a configuration verification, a preoperational inspection as required by the applicable MRCs, and a functional test. The activity transferring the SE may elect to increase the depth of inspection if the SE condition AI-25
