SAIB: CE-13-45 Engine Exhaust; Tailpipe V-band Couplings

This Special Airworthiness Information Bulletin (SAIB) informs owners, operators, and maintenance personnel of turbocharged, reciprocating engine-powered airplanes about the potential for in-flight fire as a result of failure of the exhaust system V-band coupling securing the tailpipe to the turbocharger, the wastegate overboard, or any other exhaust system V-band coupling.


The FAA has issued airworthiness directives (AD) in the past concerning V-band couplings for specific airplane models. These ADs remain in effect where applicable. For those airplanes not affected by a V-band coupling AD, this airworthiness concern is not considered an unsafe condition at this time that would warrant AD action under Title 14 of the Code of Federal Regulations, part 39.
