NTSB Safety Recommendation — Aviation
Recommendation text
TO THE FEDERAL AVIATION ADMINISTRATION: Require the McDonnell Douglas aircraft corporation to immediately redefine the "maximum brake wear" limits for the dc-10-30 and -40 airplanes to ensure that the brake kinetic energy capacity ratings for wheel brake assemblies that are at the allowable "maximum brake wear" limit are not 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. (Superseded by A-90-26) (Urgent)
In plain language (FlightFinder summary)
The Federal Aviation Administration (FAA) is required to direct McDonnell Douglas to immediately revise the 'maximum brake wear' limits for DC‑10‑30 and ‑40 aircraft. The revision must ensure that the brake kinetic energy capacity at the maximum allowable wear is not lower than the energy absorption needed for the most demanding certified combination of weight, airspeed, altitude, temperature, runway slope, and tailwind.
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.
