Recommendation text
THE NTSB RECOMMENDS THAT THE FAA: REQUIRE, AS AN INTERIM MEASURE, PENDING IMPLEMENTATION OF A-98-19, THAT CRITICAL ROTATING TITANIUM ENGINE COMPONENTS THAT HAVE BEEN IN SERVICE FOR AT LEAST 2 YEARS RECEIVE A FLUORESCENT PENETRANT INSPECTION, EDDY CURRENT, & ULTRASONIC INSPECTION OF THE HIGH-STRESS AREAS AT THE ENGINE'S NEXT SHOP VISIT OR WITHIN 2 YEARS FROM THE DATE OF THIS RECOMMENDATION, WHICHEVER OCCURS FIRST. RECOMMENDATIONS A-96-74 & A-96-75 ARE SUPERSEDED BY A-98-20.
In plain language (FlightFinder summary)
The FAA is asked to require, as an interim measure until A-98-19 is implemented, that critical rotating titanium engine components with at least 2 years of service receive fluorescent penetrant, eddy current, and ultrasonic inspections of high-stress areas. These inspections must occur at the engine's next shop visit or within 2 years, whichever comes first.
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.
