assembly, disassembly, maintenance, servicing and handling. Airborne Missile Weapons Assembly Checklists Airborne missile and weapons assembly checklists are an abbreviated, unclassified procedural reference. These checklists can be used as a guide for step-by-step assembly of missiles and weapons. They are provided as a convenient “line maintenance” reference document. The checklist manual is used as a backup in the event of difficulty. Structural Repair Manual (SRM) The SRM is used as a guide in making structural repairs to the airframe. It contains general information on airframe sealing, control surface rebalancing, general shop practices, damage evaluation and support of structure. and a description of the structure. Descriptions of structures are made by using indexed illustrations and repair drawings. SRMs contain specialized repair information required by maintenance personnel to determine the extent of aircraft structural damage. It also contains instructions for performing a permanent or onetime flight repair. Basic structural repair data, common to all aircraft, is released in a general engineering series manual, General Manual for Structural Repair, NAVAIR 01-1A-1. Aircraft structural repair manuals are prepared by the original design manufacturer. They contain aircraft specific information and are considered a supplement to the general series (01-1A) manuals discussed earlier. 2-26 The SRM for most new aircraft is published in two volumes because the volumes are used by different activities. Volume I is used by all levels of maintenance. Volume II supplements volume I, and contains information for use at intermediate- and depot-level facilities. You can identify the SRM by a -3 in the manual code. The two volumes are further identified by an additional  dash  number;  for  example, NAVAIR-01-75PAA-3-1. This is the code for volume I of the SRM for the P-3A. Each volume of the SRM is divided into sections. Section I contains genera! information. Each of the other sections contains more specific information. These sections cover portions of the aircraft, such as wings, tail, fuselage, landing gear, and engines. There is also a section that covers typical repairs. The scope of SRMs is being revised to expand and complement their application. The manuals are to be published as four volumes: (1) structural repair, (2) corrosion control, (3) nondestructive inspection, and (4) an illustrated parts breakdown (IPB). Before you attempt to use the SRM, you should read the introduction in volume I. It includes information on how to use the manual. NOTE: Since the formats of SRMs differ, the instructions on how to use a particular manual also may differ from other SRMs. POWER PLANT MANUALS (02 SERIES) Power plants are reciprocating engines, jet propulsion engines, jet propulsion/turboshaft engines, rocket-type jet engines and Auxiliary Power Units (APU). Organizational (installed) maintenance is covered in the power plants volume of the MIM that is prepared by the aircraft designer. However, intermediate and depot (uninstalled) information is defined in specialized engine publications prepared by the engine manufacturer. These manuals include information on intermediate servicing and repair, complete engine repair (CER), overhaul, and an IPB. In some cases, CER is supported by a deck of Complete Engine Repair Requirements Cards (CERRCs). Unique to engine systems is a Three-degree, Gas Turbine Engine Repair Program at the intermediate maintenance level. Under this program, each engine intermediate maintenance manual defines specific engine maintenance actions as either first-, second-, or third-degree functions. Specific guidelines and responsibility information are provided in OPNAVINST 4790.2. In most power plant manuals, the maintenance and service instructions manual is identified by a -2 or a -502 in part III of the NAVAIR publication number. These manuals contain all the information necessary for you to routinely service and maintain the engine models covered. They also include instructions for troubleshooting, dismantling, reassembling, and testing. Under the NAVAIR publication numbering system, the overhaul instructions manual is identified by a -3 or a -503 in part III of the publication number. This manual
