NTSB Safety Recommendation — Aviation
Recommendation text
THE NSTB RECOMMENDS THAT THE FAA: AMEND AIRWORTHINESS DIRECTIVE 75-23-08 R5 TO REQUIRE THAT ALL CESSNA TWIN-ENGINE, TURBOCHARGED ENGINE EXHAUST SYSTEM COMPONENTS THAT ARE MADE FROM STAINLESS STEEL OR THAT CANNOT BE CONCLUSIVELY DETERMINED TO BE MADE WITH INCONEL RECEIVE REPETITIVE VISUAL INSPECTIONS OF THE DISASSEMBLED EXHAUST SYSTEM. ANY WORN, DAMAGED, OR OTHERWISE DEFECTIVE EXHAUST SYSTEM COMPONENTS OR ASSEMBLIES SHOULD BE REPLACED BEFORE ANY FURTHER FLIGHT.
In plain language (FlightFinder summary)
The FAA is asked to amend Airworthiness Directive 75-23-08 R5 to mandate repetitive visual inspections of the disassembled exhaust system for Cessna twin-engine, turbocharged aircraft. This applies to exhaust components made of stainless steel or those whose material cannot be definitively identified as Inconel. Any worn, damaged, or defective parts must be replaced before further flight.
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.
