Background

Current TSO-C26c, Aircraft Wheels and Wheel-Brake Assemblies, with Addendum I, dated 5/18/84, prescribes the MPS that Part 23, 25, 27, and 29 aircraft wheels and wheel-brake assemblies must meet to be identified with the applicable TSO marking TSO-C135, Transport Airplane Wheels and Wheel and Brake Assemblies, issued on 5/2/02, prescribes the MPS for Part 25 airplanes as of that date. This proposed revision to TSO-C26c prescribes the MPS for Parts 23, 27, and 29 for new applications, and major design changes to aircraft wheels, brakes and wheel/brake assemblies, submitted after the effective date of this proposed TSO-C26d. This proposed revision also reflects the latest industry practices.
