ATA - The ATA Chapter numbers provide a common referencing standard for all commercial aircraft documentation. The standard numbering system is controlled and published by the Air Transport Association in ATA Specification 100 - Specification for Manufacturers' Technical Data.
When available, you can click on the icon to display the pop-up window and select a valid ATA Code.

NOTE: The ATA Chapter must be setup in the associated Validation Table and can be setup with 2, 4 or 6 digits.

Following ATA Chapters are pre-defined:

"05": For Chapter 05 Maintenance Inspections,

"98": For Non-repetitive SB's and AD's, and
