A-83-073
NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: EVALUATE THE ELECTRICAL CIRCUIT PROTECTION, INCLUDING REDUCED CIRCUIT BREAKER RATED VALUES AND INTEGRAL COMPONENT THERMAL PROTECTION DEVICES, NEEDED TO ELIMINATE THE POTENTIAL FOR OVERHEATING OF THE WIRING AND COMPONENTS IN THE LAVATORY FLUSHING PUMP MOTOR SYSTEMS IN TRANSPORT CATEGORY AIRPLANES AND ISSUE AIRWORTHINESS DIRECTIVES AS REQUIRED. (URGENT) (Supersedes Safety Recommendations A-73-068, A-73-070, and A-74-005)
In plain language (FlightFinder summary)
The NTSB asks the FAA to assess how electrical circuits in transport-category airplane lavatory flushing pump motor systems are protected, including using lower-rated circuit breakers and thermal protection devices, to prevent wiring and component overheating, and to issue any necessary airworthiness directives.
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.
