NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FAA: REQUIRE A REPETITIVE BORESCOPE INSPECTION OF PRATT & WHITNEY JT8D-1 THROUGH -17AR ENGINES TO CHECK FOR FRACTURED LOW PRESSURE COMPRESSOR (LPC) REAR TIERODS AND, IF FOUND, REQUIRE THE REMOVAL OF THOSE ENGINES FROM SERVICE FOR REPAIR. PERIODIC REINSPECTIONS SHOULD CONTINUE UNTIL A NON-DESTRUCTIVE INSPECTION OF THE LPC REAR TIERODS IS PERFORMED OR THE TIERODS ARE REPLACED.
In plain language (FlightFinder summary)
The FAA is asked to require repetitive borescope inspections of Pratt & Whitney JT8D-1 through -17AR engines to detect fractured low pressure compressor (LPC) rear tierods, and to mandate removal of engines with such fractures for repair. Periodic reinspections must continue until a non-destructive inspection of the LPC rear tierods is performed or the tierods are replaced.
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.
