ATA Spec 2400-2023 Allowable Configuration Data Exchange Standar

Allowable Configuration Data Exchange Standard

Abstract

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. This specification defines part configuration attributes and concepts which integrate engineering product structure with allowable part usage by Function Position installation through the life of an aircraft. The Allowable Configuration file is primarily machine readable, allowing aircraft operators to perform automated validation of actual configuration compliance and, more efficiently, to identify replacement parts 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.
