NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: REQUIRE THAT ALL PILOT OPERATING HANDBOOKS/AIRPLANE FLIGHT MANUALS APPLICABLE TO AIRCRAFT CERTIFIED FOR FLIGHT IN ICING CONDITIONS CONTAIN PRECAUTIONARY OPERATIONAL INFORMATION TO HELP ENSURE THAT ICE WILL NOT ACCUMULATE ON THE UNDESURFACE OF THE WING AFT OF THE AREA PROTECTED BY THE DEICER BOOTS OR ON OTHER UNPROTECTED AREAS OF THE AIRPLANE. THE INFORMATION SHOULD INCLUDE SPECIFICATION OF A MINIMUM INDICATED AIRSPEED THAT SHOULD BE MAINTAINED DURING SUSTAINED OPERATIONS IN ICING CONDITIONS.
In plain language (FlightFinder summary)
The Federal Aviation Administration is asked to mandate that Pilot Operating Handbooks and Airplane Flight Manuals for aircraft certified for icing conditions include precautionary information to prevent ice buildup on unprotected wing surfaces and other areas. This information should specify a minimum indicated airspeed to be maintained during sustained flight in icing conditions.
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.
