    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.
