A-96-074
NTSB Safety Recommendation — Aviation
Recommendation text
TO THE FEDERAL AVIATION ADMINISTRATION: Require that, within 500 cycles of FAA approval of an engine "on wing" eddy current inspection process for Pratt and Whitney JT8D-200 series engine fan hub tierod holes, this inspection be performed on those hubs that have accumulated more that 10,000 cycles since new, prioritize the inspections to ensure that the fan hubs most at risk (data suggest those hubs with 10,000 to 15,000 cycles since new) are inspected first. This inspection can be superseded by the redundant inspection urged in safety recommendation A-96-75. (Superseded by A-98-19 and A-98-20) (Urgent)
In plain language (FlightFinder summary)
The Federal Aviation Administration is asked to mandate that, within 500 flight cycles after it approves a new on-wing eddy current inspection method for Pratt & Whitney JT8D-200 series engine fan hub tierod holes, the inspection be performed on hubs that have accumulated more than 10,000 cycles since new. Inspections should be prioritized on the most at-risk hubs, specifically those with 10,000 to 15,000 cycles. The requirement may be superseded by the redundant inspection urged in safety recommendation A-96-75.
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.
