NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: ISSUE AN ADVISORY CIRCULAR DESCRIBING THE DAMAGE TO TIRES THAT CAN RESULT FROM ELEVATED BRAKE TEMPERATURES. EMPHASIZE THE IMPORTANCE OF VISUALLY INSPECTING BEAD SEAT AREAS PRIOR TO MOUNTING AND THE NEED TO PERFORM BEAD-TO-BEAD HOLOGRAMS FOR HEAT DAMAGE WHENEVER EXPOSURE TO HIGHER-THAN-NORMAL BRAKE TEMPERATURES IS SUSPECTED, INCLUDING OCCURENCES WHERE THERE HAS BEEN FASTER-THAN-NORMAL ROTOR WEAR. EMPHASIZE THE NEED TO REPLACE TIRES SUSPECTED OF HAVING BEEN SUBJECTED TO HEAT DAMAGE AND BRAKE LININGS SUSPECTED OF CAUSING FASTER-THAN-NORMAL ROTOR WEAR OR HIGHER-THAN-NORMAL BRAKE TEMPERATURES FOR ANY REASONS AS SOON AS POSSIBLE TO MINIMIZE HEAT DAMAGE TO TIRES.
In plain language (FlightFinder summary)
The FAA is asked to publish an advisory circular that describes how elevated brake temperatures can damage tires. The circular should stress visually inspecting bead seat areas before mounting and using bead-to-bead holograms to detect heat damage when high brake temperatures are suspected. It should also highlight the importance of promptly replacing tires that may have heat damage and brake linings that may be causing faster-than-normal rotor wear or elevated brake temperatures.
This plain-language summary is written by FlightFinder to explain the recommendation above. It is not the official wording — the verbatim NTSB text is quoted above.
