NTSB Safety Recommendation — Aviation
Recommendation text
TO THE FEDERAL AVIATION ADMINISTRATION: Require Boeing to develop recovery strategies (for example, checklists, procedures, or memory items) for pilots of 737 airplanes that do not have a mechanical override feature for a jammed elevator in the event of a full control deflection of the elevator system and incorporate those strategies into pilot guidance. Within those recovery strategies, the consequences of removing all hydraulic power to the airplane as a response to any uncommanded control surface should be clarified.
In plain language (FlightFinder summary)
The Federal Aviation Administration is asked to require Boeing to create recovery strategies, such as checklists or procedures, for 737 pilots without a mechanical override for a jammed elevator, and include those strategies in pilot guidance. The strategies should also clarify the effects of removing all hydraulic power in response to any uncommanded control surface.
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.
