NTSB Safety Recommendation — Aviation
Recommendation text
TO THE FEDERAL AVIATION ADMINISTRATION: Require operators to permanently (1) track end play measures according to airplane registration number and jackscrew assembly serial number, (2) calculate and record average wear rates for each airplane based on end play measurements and flight times, and (3) develop and implement a program to analyze these data to identify and determine the cause of excessive or unexpected wear rates, trends, or anomalies. The Federal Aviation Administration (FAA) should also require operators to report this information to the FAA for use in determining and evaluating an appropriate end play check interval.
In plain language (FlightFinder summary)
The Federal Aviation Administration (FAA) is asked to require operators to track end play measurements by airplane registration and jackscrew serial number, calculate average wear rates from measurements and flight times, and create a data analysis program to identify causes of abnormal wear. The FAA should also require operators to report this data to help determine appropriate end play check intervals.
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.
