Chapter 12. Publications, Forms, & Records Non-FAA Documents Air Transport Association (ATA) 100 To standardize the technical data and maintenance activities on large and therefore complex aircraft, the ATA has established a classification of maintenance related actions. These are arranged with sequential numbers assigned to ATA chapters. These chapters are consistent regardless of which large aircraft is being worked on. [Figure 12-16] Manufacturers’ Published Data The original equipment manufacturer (OEM) is usually the best source of information for the operation of and maintenance on a particular product. Whether the product is a complete aircraft (Cessna 172, Boeing 777, or Airbus A380), an engine, or a component of the engine (i.e., thrust reverser, hydraulic pump, generator, and so forth), the manufacturer is required by 14 CFR part 21, §21.5 to provide a current approved airplane or rotorcraft flight manual and (if applicable) a rotorcraft maintenance manual. If the product is a TC’d or STC’d item, §21.50 requires the holder of the design approval to provide one set of complete Instructions for Continued Airworthiness (ICAs). Additional requirements for ICAs are specified in §§23.1529, 25.1529, 27.1529 and 29.1529. These sections further refer the reader to appendix G (for parts 23 and 25) and appendix A (for parts 27 and 29). Regardless of which appendix is referred, the requirements in the appendix for the ICA are as follows: General: The aircraft ICA must contain instructions for continued airworthiness for each engine, propeller, or appliance and the interface of those appliances and products with the aircraft. Format: The ICA must be in the form of a manual or manuals appropriate to the data being provided. Content: The manual contents must be in English and must include: Introductory information including an explanation of the airplane’s features and data as necessary to perform maintenance or preventive maintenance. A description of the aircraft and its systems, including engine, propeller, and appliances. Basic operating information describing how the aircraft and its components are controlled. Servicing information with such detail as servicing parts, task capacities, types of fluid to be used, applicable pressures for the various systems, access panels for inspection and servicing, lubrication points, and types of lubricants to be used. The maintenance instructions must include the following data: Recommended schedule for cleaning, inspecting, adjusting, testing, and lubricating the various parts. Applicable wear tolerances. Recommended overhaul periods. Details for an inspection program that identifies both the frequency and the extent of the inspections necessary to provide for continued airworthiness. Troubleshooting information. The order and method for proper removal and replacement of parts. Procedures for system testing during ground operations. Diagrams for structural access plates. Details for application of special inspection techniques. Information concerning the application of protective treatments after inspection. Information relative to the structural fasteners. List of any special tools needed.
