SUPPLEMENTARY INFORMATION: 

Comments Invited

    You are invited to comment on the proposed TSO by submitting 
written data, views, or arguments to the above address. Comments 
received may be examined, both before and after the closing date, in 
room 815 at the above address, weekdays except federal holidays,

Background

    TSO-C 135 is being revised to remove an installation criterion that 
is not appropriate at the article level. (Appendix 1 Para. 3.2.2.2., 
the last sentence.) The revision also adds Appendix 2 to the proposed 
TSO-C135a's MPS for transport airplane wheel and brake assemblies with 
electrically actuated brakes. The aforementioned MPS defines the 
standards for wheel and brake assemblies to be used on airplanes 
certified under 14 CFR part 25. These standards were defined by the 
FAA, adopted in SAE Aerospace Standard (AS) 5663, Minimum Performance 
Requirements for Transport Airplane Wheel and Brake Assemblies Using 
Electric Power Actuation dated January 2007. Note that compliance with 
this specification is not considered approval for installation on any 
transport airplane.
