NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: REQUIRE BRITISH AEROSPACE, INC. TO SHOW, BY FLIGHT TEST, THAT THE LIMITATION TO FLAPS 35 DEGREES, CURRENTLY INCORPORATED INTO ALL BA-3200 AIRPLANES AND AVAILABLE IN KIT FORM FOR INSTALLATION ON BA-3100 AIRPLANES, PROVIDES AN ADEQUATE SAFETY MARGIN AGAINST TAILPLANE STALL IN ICING CONDITIONS; AND IF THE MARGIN IS ADEQUATE, REQUIRE OPERATORS OF BA-3100 AIRPLANES TO INSTALL THE FLAP EXTENSION LIMITATION MODIFICATION ON THE AIRPLANE. IF THE MARGIN IS INADEQUATE, REQUIRE APPROPRIATE CHANGES TO ASSURE ITS ADEQUACY.
In plain language (FlightFinder summary)
The FAA is asked to require British Aerospace, Inc. to demonstrate through flight testing that the flap extension limitation to 35 degrees, currently in place on BA-3200 airplanes and available as a kit for BA-3100 airplanes, offers an adequate safety margin against tailplane stall in icing conditions. If the margin is adequate, operators of BA-3100 airplanes must install the modification; if not, the FAA must require appropriate changes to ensure the margin is adequate.
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.
