Aircraft Wheel Brake Steel Friction Mix Minor Changes
AIR8983
This SAE Aerospace Informational Report (AIR) provides information on when a modification to a steel brake is considered a minor change and how a minor change would often be verified. This document is intended to give information in support of the verification of steel friction mix minor changes for Part 23, 25, 27 & 29 aircraft wheel braking applications by TSO or PMA holders. Information included herein was partially derived from previous steel friction mix minor and major change classifications.
Rationale: This document provides information describing when changes to a steel brake could typically be considered a minor change and how those minor changes are often verified. Information is also provided on what may be considered a major change to a steel brake.
