Revision of Braking Systems; Airworthiness Standards To Harmonize With European Airworthiness Standards for Transport Category Airplanes

Resumo

This document seeks public comment on changes proposed as a result of the comments received on Notice No. 99-16. The changes proposed in this supplemental notice would require an additional dynamometer test during brake qualification, namely, an accelerate-stop test with the brake heat sink in a new condition (also called a new brake rejected takeoff (RTO) test) for part 25 transport category airplanes. The new proposed brake test could result in a minimal cost increase for some part 25 small airplanes. These changes are intended to benefit the public interest by standardizing certain requirements, concepts, and procedures in the airworthiness standards without reducing, but potentially enhancing, the current level of safety.
