NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: REQUIRE THE REVISION OF THE ABNORMAL PROCEDURES SECTION OF BOEING 727 AIR CARRIER OPERATOR FLIGHT MANUALS, AS NEEDED, REGARDING THE LANDING GEAR UNSAFE INDICATION, TO INCLUDE ADDITIONAL INFORMATION RELEVANT TO THE GEAR POSITION INDICATOR LIGHTS AND THE LANDING GEAR WARNING HORN SYSTEM, AND THE FACT THAT THEY ARE NOT INDEPENDENT AND ARE NOT REDUNDANT LANDING GEAR POSITION INDICATING SYSTEMS.
In plain language (FlightFinder summary)
The NTSB asks the FAA to mandate updates to the abnormal procedures section of Boeing 727 operator flight manuals. These updates should clarify that the landing gear position indicator lights and warning horn are not independent or redundant systems for indicating unsafe gear.
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.
