NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: REQUIRE FOKKER TO DETERMINE HOW TAKEOFF PERFORMANCE AND STALL MARGIN WOULD BE AFFECTED BY USING A LOWER INITIAL TARGET PITCH ATTITUDE ON F-28 AND F-100 AIRPLANES IN THE EVENT THAT UNDETECTED UPPER WING ICE CONTAMINATION IS PRESENT, AND CHANGE THE NORMAL OPERATING PROCEDURES IF TAKEOFF PERFORMANCE REQUIREMENTS CAN BE MET WHILE THE STALL MARGIN IS IMPROVED.
In plain language (FlightFinder summary)
The Federal Aviation Administration is asked to require Fokker to study how a lower initial target pitch attitude would affect takeoff performance and stall margin on F-28 and F-100 airplanes when undetected upper wing ice contamination is present, and to update the normal operating procedures if the performance requirements can still be satisfied while improving the stall margin.
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.
