These are arranged with sequential numbers assigned to A4A chapters.ĪTA iSpec 2200 is a global aviation industry standard for the content, structure, and electronic exchange of aircraft engineering and maintenance information. To standardize the technical data and maintenance activities on aircraft, the A4A has established a classification of maintenance related actions. Numbering in each major system provides an arrangement for breaking the system down into several subsystems. The A4A iSpec 2200 divides the aircraft into systems, such as air conditioning, that covers the basic air conditioning system (A4A 21). In 2000, ATA Spec 100 and ATA Spec 2100 were incorporated into ATA iSpec 2200: Information Standards for Aviation Maintenance. In 2000: Creation of the ATA specification 2200 (Information Standards for Aviation Maintenance) based on the two specifications i.e ATA 100 and ATA 2100. In 1994: Creation of the ATA specification 2100 – digital data standards for aircraft support For example, if seeking information about the fuel system on any aircraft, that information is always found in section (chapter) 28.īefore 1989: ATA specification 100 – manufacturers’ technical data

As a result of this standardization, maintenance technicians can always find information regarding a particular system in the same section of an aircraft maintenance manual, regardless of manufacturer. These two specifications evolved into one document called ATA iSpec 2200. Eventually, ATA Spec 2100 was developed for electronic documentation. Over the years, Spec 100 has been continuously revised and updated. The original specification was called ATA Spec 100. This document provides the industry-wide standard for aircraft systems numbering, often referred to as ATA system or chapter numbers. These documents are used by airlines and other segments of the industry in the maintenance of their respective products. The Air Transport Association released the ATA Specification to standardize the format in which maintenance information is presented in aircraft maintenance manuals.ĪTA Specification 2200 contains format and content guidelines for technical manuals written by aviation manufacturers and suppliers.
