The Joint Aircraft ......System/Component (JASC) Code Tables was a modified version of the Air Transport Association of America (ATA), Specification 100 code. It was developed by the FAA's, Regulatory Support Division (AFS-600). This code table was constructed by using the new JASC code four digit format, along with an abbreviated code title. The abbreviated titles have been modified in some cases to clarify the intended use of the accompanying code. The final version of th
JASC/ATA 100 code
was released by the FAA in 1999. In 2000 the ATA Technical Information and Communications Committee (TICC) developed a new consolidated specification for the commercial aviation industry, ATA iSpec 2200. It includes an industry-wide approach for aircraft system numbering, as well as formatting and data content standards for documentation output. The main objectives of the new specification are to minimize cost and effort expended by operators and manufacturers, improve information quality and timeliness, and facilitate manufacturers' delivery of data that meet airline operational needs. More recently, the international aviation community developed the

Some website, like aircraft parts resellers, will sometimes refer to ATA 72R or 72T for reciprocating and turbine engines (jet or turboprop), this nomenclature is not part per se of the ATA numbering definition. The ATA 72 subchapter are different for reciprocating engines and turbine engines. Under JASC/ATA 100 the reciprocating engine are now under ATA 85.
