CESSNA A185F AMPHIBIAN — Airworthiness Directives

This document is an Airworthiness Directive (AD) issued by the Federal Aviation Administration (FAA) that addresses safety concerns related to turbocharged, reciprocating engine-powered airplanes, including the Beechcraft 60 Duke. It specifically focuses on the failures of spot-welded, multi-segment v-band couplings at the tailpipe to turbocharger exhaust housing flange. The AD establishes a life limit for these couplings and mandates repetitive inspections to ensure safety. The directive is a response to multiple incidents and accidents linked to these couplings, emphasizing the importance of compliance to prevent potential in-flight fires and loss of control of the aircraft. This AD is effective from July 17, 2023, and is crucial for operators and maintenance personnel to understand and implement the required actions to maintain airworthiness.

• Life limit of 500 hours for spot-welded, multi-segment v-band couplings.
• Mandatory inspections every 6 months or 100 hours of flight time for two years after the AD's effective date.
• Significant safety concerns linked to v-band coupling failures leading to in-flight fires.
• Compliance with previous NTSB safety recommendations is crucial for safety.
• Costs for compliance may vary, but safety is the priority.
