NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: REVISE 14 CFR 25.735(F) TO REQUIRE THAT THE BRAKE KINETIC ENERGY CAPACITY RATINGS FOR WHEEL BRAKE ASSEMBLIES THAT ARE AT THE ALLOWABLE "MAXIMUM BRAKE WEAR" LIMIT MAY NOT BE LESS THAN THE KINETIC ENERGY ABSORPTION REQUIREMENTS THAT RESULT FROM THE CRITICAL COMBINATION OF WEIGHT, TRUE AIRSPEED, ALTITUDE, TEMPERATURE, RUNWAY SLOPE AND TAIL WIND COMPONENT FOR WHICH THE AIRPLANE IS CERTIFIED. (URGENT)
In plain language (FlightFinder summary)
The NTSB asks the FAA to revise regulation 14 CFR 25.735(f) so that the kinetic energy capacity rating for wheel brake assemblies at the maximum allowable wear limit must be no less than the energy absorption required under the most critical combination of weight, true airspeed, altitude, temperature, runway slope, and tailwind for which the airplane is certified.
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.
