A-04-057
NTSB Safety Recommendation — Aviation
Recommendation text
TO THE FEDERAL AVIATION ADMINISTRATION: After the yaw axis certification standard recommended in Safety Recommendation A-04-56 has been established, review the designs of existing airplanes to determine if they meet the standard. For existing airplanes designs that do not meet the standard, the FAA should determine if the airplanes would be adequately protected from the adverse effects of a potential aircraft-pilot coupling (APC) after rudder inputs at all airspeeds. If adequate protection does not exist, the FAA should require modifications, as necessary, to provide the airplanes with increased protection from the adverse effects of a potential APC after rudder inputs at high airspeeds.
In plain language (FlightFinder summary)
The Federal Aviation Administration is asked to first establish a yaw axis certification standard based on Safety Recommendation A-04-56, then review existing airplane designs for compliance. For designs that do not meet the standard, the FAA must assess whether they are adequately protected from adverse effects of aircraft-pilot coupling (APC) after rudder inputs at all airspeeds. If protection is insufficient, the FAA should require modifications to enhance protection at high airspeeds.
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.
