NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: REQUIRE ALL OPERATORS OF JT8D-200 SERIES ENGINES THAT HAVE NOT BEEN MODIFIED TO REDUCE THE RISK OF FAILURE OF THE LOW PRESSURE TURBINE VANE CLUSTER ANTI-ROTATION PINS TO IMPLEMENT A FEDERAL AVIATION ADMINISTRATION APPROVED INSPECTION AND REPLACEMENT PROGRAM THAT WILL PROVIDE EARLY DETECTION OF ANTI-ROTATION PIN FRACTURE AND THAT WILL SPECIFY A CRITERIA FOR REMOVAL AND REPLACEMENT OF BROKEN PINS AND THE REPLACEMENT OF EXISTING PINS WITH IMPROVED PINS WITHIN A SPECIFIED TIME BUT NOT LATER THAN THE NEXT SHOP VISIT FOR THE LOW PRESSURE TURBINE MODULE. (URGENT)
In plain language (FlightFinder summary)
The FAA is asked to require operators of JT8D-200 series engines that have not been modified to adopt an approved inspection and replacement program. The program aims to detect early fractures of the low pressure turbine vane cluster anti-rotation pins and specify criteria for removing broken pins and replacing existing pins with improved ones, within a specified time no later than the next shop visit for the low pressure turbine module. The recommendation is urgent.
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.
