NTSB Safety Recommendation — Aviation
Recommendation text
TO THE FEDERAL AVIATION ADMINISTRATION: Evaluate the history of uncommanded air turbine starter valve (ATSV)-Open events in the MD-80 fleet and the effectiveness of coupling the ATSV-Open light to the Master Caution system to determine whether all MD-80 airplanes need to be modified to couple the ATSV-Open light to the Master Caution system. Once the evaluation is completed, require any necessary modifications.
In plain language (FlightFinder summary)
The Federal Aviation Administration is asked to review past uncommanded air turbine starter valve (ATSV)-Open events in MD-80 aircraft and assess whether connecting the ATSV-Open warning light to the Master Caution system is effective. Based on that evaluation, the FAA must mandate any necessary modifications for all MD-80 airplanes.
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.
