NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FAA: AMEND AIRWORTHINESS DIRECTIVE 75-23-08 R5 TO REQUIRE THE RECURRING VISUAL INSPECTION SET FORTH IN THE AD OF ALL-INCONEL EXHAUST SYSTEM COMPONENTS IN CESSNA TWIN-ENGINE, TURBOCHARGED AIRPLANES. IN ADDITION, THE INCONEL EXHAUST SYSTEM PARTS SHOULD BE PERMANENTLY MARKED TO DEMONSTRATE THAT THEY ARE MADE WITH INCONEL MATERIAL. ANY WORN, DAMAGED, OR OTHERWISE DEFECTIVE EXHAUST SYSTEM COMPONENTS OR ASSEMBLIES SHOULD BE REPLACED BEFORE ANY FURTHER FLIGHT.
In plain language (FlightFinder summary)
The NTSB asks the FAA to revise Airworthiness Directive 75-23-08 R5 to mandate periodic visual inspections of all-Inconel exhaust system parts on Cessna twin-engine turbocharged airplanes. The AD should also require permanent marking of Inconel exhaust parts to verify their material, and mandate replacement of any worn, damaged, or defective exhaust components 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.
