NTSB Safety Recommendation — Aviation
Recommendation text
TO THE FEDERAL AVIATION ADMINISTRATION: Evaluate the inspection methods that could be used to determine the integrity of the exhaust systems and require additional procedures that are effective; establish a recommended replacement time interval for exhaust systems in general aviation aircraft with reciprocating engines and cabins, taking into consideration the factors that cause or contribute to the deterioration or erosion of exhaust systems. After the establishment of this recommended replacement time interval, issue a notice to all 14 Code of Federal Regulations (CFR) Part 91 owners and operators advising them of these recommended replacement time intervals and require adherence to the replacement time intervals for 14 CFR Part 135 owners and operators.
In plain language (FlightFinder summary)
The Federal Aviation Administration is asked to evaluate inspection methods for exhaust system integrity and to mandate effective additional procedures. It should also set a recommended replacement time interval for exhaust systems in general aviation aircraft with reciprocating engines and cabins, based on factors that cause deterioration or erosion. After setting that interval, the FAA must notify 14 CFR Part 91 owners and operators of the recommendation and require compliance for Part 135 operators.
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.
