NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: REQUIRE THAT THE ELECTRICAL ACTUATING SYSTEMS FOR NONPLUG CARGO DOORS ON TRANSPORT-CATEGORY AIRCRAFT PROVIDE FOR THE REMOVAL OF ALL ELECTRICAL POWER FROM CIRCUITS ON THE DOOR AFTER CLOSURE (EXCEPT FOR ANY INDICATING CIRCUIT POWER NECESSARY TO PROVIDE POSITIVE INDICATION THAT THE DOOR IS PROPERLY LATCHED AND LOCKED) TO ELIMINATE THE POSSIBILITY OF UNCOMMANDED ACTUATOR MOVEMENTS CAUSED BY WIRING SHORT CIRCUITS.
In plain language (FlightFinder summary)
The NTSB asks the FAA to require that on transport-category aircraft, the electrical systems that operate nonplug cargo doors must shut off all power to door circuits after closing, except for circuits that show the door is correctly latched and locked, in order to prevent accidental movements caused by short circuits.
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.
