NTSB Safety Recommendation — Aviation
Recommendation text
TO THE FEDERAL AVIATION ADMINISTRATION: Conduct a detailed engineering review of the B-737 yaw damper system, and require the Boeing Commercial Airplane Group to redesign the yaw damper system, as necessary, to eliminate the potential for sustained uncommanded yaw damper control events. After the B-737 yaw damper system is redesigned, issue an airworthiness directive to require the installation of the improved yaw damper system on all B-737 series aircraft.
In plain language (FlightFinder summary)
The Federal Aviation Administration must conduct a detailed engineering review of the Boeing 737 yaw damper system and require Boeing to redesign it to eliminate sustained uncommanded yaw damper events. After the redesign, the FAA must issue an airworthiness directive mandating the improved system on all B-737 series aircraft.
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.
