NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: ISSUE AN AIRWORTHINESS DIRECTIVE (1) TO REQUIRE AN IMMEDIATE INSPECTION OF THE LAVATORY FLUSHING PUMP MOTOR AND THE ASSOCIATED WIRING HARNESSES BETWEEN THE TIMING COMPONENTS AND THE MOTOR IN THE LAVATORIES OF TRANSPORT CATEGORY AIRPLANES FOR EVIDENCE OF MOISTURE-INDUCED CORROSION OR DETERIORATED INSULATION AND TO REQUIRE THAT FLUSHING PUMP MOTORS OR WIRING HARNESSES WHICH EXHIBIT SUCH CONDITIONS BE REPLACED, AND (2) TO ESTABLISH APPROPRIATE PERIODIC INTERVALS FOR REPETITION OF THESE INSPECTIONS. (URGENT)
In plain language (FlightFinder summary)
The NTSB asks the FAA to issue an Airworthiness Directive requiring immediate inspection of lavatory flushing pump motors and their wiring harnesses in transport category airplanes for moisture-induced corrosion or deteriorated insulation, and to replace any affected parts. The directive must also establish periodic intervals for repeating these inspections.
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.
