CESSNA 310F — Airworthiness Directives

This document is a proposed airworthiness directive (AD) issued by the FAA, aimed at addressing safety concerns related to turbocharged, reciprocating engine-powered airplanes and helicopters, including the Cessna 421 series. The AD focuses on the failures of spot-welded, multi-segment v-band couplings that connect the exhaust tailpipe to the turbocharger exhaust housing flange. The directive proposes a life limit for these couplings and mandates annual inspections to ensure safety. The document outlines the compliance requirements, estimated costs for operators, and the potential safety risks associated with the failure of these components. It is crucial for operators of affected aircraft to be aware of these proposed regulations to maintain safety and compliance.

• The proposed AD mandates annual inspections of spot-welded, multi-segment v-band couplings on turbocharged aircraft.
• A life limit of 500 hours TIS is established for these couplings, after which they must be removed from service.
• The AD applies to all turbocharged, reciprocating engine-powered airplanes and helicopters, including the Cessna 421 series.
• Failure to comply with the AD could lead to serious safety incidents, including in-flight fires and loss of control.
• Operators must review maintenance records within 50 hours TIS after the AD's effective date.
