SUPPLEMENTARY INFORMATION:

Background

    The standards of this TSO apply to transport category airplane 
wheels and wheel and brake assemblies used for any new TSO application 
submitted after the effective date of this TSO. Wheels and wheel and 
brake assemblies currently approved for 14 CFR part 25 airplanes under 
TSO-C26c authorization may continue to be manufactured under the 
provisions of their original approval. However, under Sec. 21.611(b) of 
Title 14, Code of Federal Regulations (14 CFR), any major design change 
to a wheel or a wheel and brake assembly previously approved under TSO-
C26c will require a new authorization under this TSO.
