NTSB Safety Recommendation — Aviation
Recommendation text
TO THE FEDERAL AVIATION ADMINISTRATION: In conjunction with representatives from engine and airframe manufacturers and pilot groups, address the issue of automatic engine response following the loss of inputs such as the N2 signal by studying events in which uncommanded and uncontrollable engine power excursions have occurred and, based on the results of the study, make appropriate recommendations that address the following: 1) automatic engine response following the loss of certain inputs; and 2) crew operating and training issues related to uncommended engine power excursions in which the throttle is ineffective.
In plain language (FlightFinder summary)
The Federal Aviation Administration is directed to collaborate with engine and airframe manufacturers and pilot groups to investigate incidents of uncommanded and uncontrollable engine power changes. Based on that study, the FAA must issue recommendations covering automatic engine reactions after the loss of certain inputs and crew training and operational procedures for power excursions where the throttle is ineffective.
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.
