NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: REQUIRE THE MANUFACTURER OF THE FAIRCHILD SWEARINGEN SA-226 AND SA-227 AIRPLANES TO REVISE THE AIRPLANE FLIGHT MANUALS TO INCLUDE A SPECIFIC "WARNING" TO PLACE THE ENGINE IGNITION SYSTEM IN THE "CONTINUOUS" MODE, (PRESENTLY LABELED OVRD) DURING FLIGHT IN ICING CONDITIONS AND AFTER DEPARTURE FROM THE ICING CONDITIONS UNTIL BOTH THE AIRFRAME AND ENGINE STRUCTURE ARE COMPLETELY FREE OF ICE.
In plain language (FlightFinder summary)
The NTSB asks the FAA to require the manufacturer of Fairchild Swearingen SA-226 and SA-227 airplanes to update the flight manuals. The update should add a warning to set the engine ignition system to "continuous" mode during flight in icing conditions and after leaving icing until all ice is gone from airframe and engine.
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.
