NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FAA: ISSUE A FLIGHT STANDARDS INFORMATION BULLETIN TO PRINCIPAL OPERATIONS INSPECTORS REQUIRING THAT ALL DC-10 FLIGHTCREWS ARE PROVIDED WITH INFORMATION REGARDING THE POTENTIAL FOR AIRPLANE ATTITUDE UPSETS CAUSED BY FAULTY CONTROL WHEEL STEERING SENSOR INPUT AND THE POTENTIAL FOR OVERSHOOTS IN RECOVERING FROM THOSE UPSETS BECAUSE OF THE AIRPLANE'S LAG IN RESPONDING TO CONTROL INPUTS AT CRUISE FLIGHT CONDITIONS.
In plain language (FlightFinder summary)
The NTSB asks the FAA to issue a Flight Standards Information Bulletin to Principal Operations Inspectors, mandating that all DC-10 flight crews be informed about the risk of attitude upsets caused by faulty control wheel steering sensor inputs and the possibility of overshooting during recovery due to the airplane's delayed response to control inputs at cruise flight 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.
