A-10-120
NTSB Safety Recommendation — Aviation
Recommendation text
TO THE EUROPEAN AVIATION SAFETY AGENCY: After the yaw axis certification standard recommended in Safety Recommendation A-10-119 has been established, review the designs of existing airplanes to determine if they meet the standard. For existing airplane designs that do not meet the standard, the European Aviation Safety Agency (EASA) 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, EASA 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 European Aviation Safety Agency (EASA) is asked to first establish a yaw axis certification standard, then review existing airplane designs to see if they comply. For designs that do not, EASA must evaluate whether they are adequately protected from adverse aircraft-pilot coupling (APC) effects following rudder inputs at all airspeeds. If protection is insufficient, EASA should mandate modifications to improve 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.
