ATA Spec 2400 is a specification for the exchange of configuration data between Aircraft Operators and Original Equipment Manufacturers (OEMs). The primary deliverable is a standardized file which defines the Allowable Configuration of an aircraft and its major components applicable to maintenance and airworthiness. The Allowable Configuration file is primarily machine readable, allowing aircraft operators to perform automated validation of actual configuration compliance rather than interpreting information from multiple maintenance source documents.

This revision includes the following updates:

  • Clarified the use of applicability in Spec 2400.
  • Added high-level process flowcharts for Allowable Configuration in Parts and Allowable Configuration in Modifications.
  • Added a business rule that Function Position Code must remain unique and persistent.
  • Added a method for indicating if a part is preferred or not.
  • Revised the mapping for software parts between Spec 2400 Allowable Configuration and ARINC 843 actual configuration.
  • Editorial and other changes noted in the specification.


Members of the ATA e-Business Program have access to this specification and all other ATA e-business specifications for free. To learn more about the cost and benefits of membership or to get involved in the standards development process, go to http://www.ataebiz.org.
