NTSB Safety Recommendation — Aviation
Recommendation text
TO THE FEDERAL AVIATION ADMINISTRATION: Identify all currently certificated transport-category airplanes for which system safety assessments for landing gear systems did not consider human error that could lead to cross-wiring of antiskid brake system components, including the wheel speed transducers, and require manufacturers of transport-category airplanes without such assessments to perform the assessments and then implement mitigations to prevent cross-wiring of antiskid brake system components.
In plain language (FlightFinder summary)
The Federal Aviation Administration is asked to find all transport-category airplanes with current certificates where system safety assessments for landing gear systems did not account for human error that could cause cross-wiring of antiskid brake system components, including wheel speed transducers. The FAA must then require airplane manufacturers lacking such assessments to perform them and put mitigations in place to prevent cross-wiring.
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.
