Bonanza AD Fix Uses Cessna Part

Gemini Sparkle

Key Takeaways:

  • The FAA issued an Airworthiness Directive (AD) grounding certain Bonanza models (A36TC and B36TC) after an exhaust v-band clamp failure caused a fatal accident.
  • The manufacturer, Textron, lacked stock of the required replacement clamps, hindering compliance with the AD.
  • The American Bonanza Society Air Safety Foundation successfully proposed an alternative: using readily available exhaust clamps with a Cessna part number, which the FAA has approved as an alternative means of compliance.

The FAA says owners of certain Bonanza models can use an exhaust clamp made for Cessna aircraft as an alternative means of compliance for an AD that has grounded some Bonanzas. According to AOPA, the agency issued the AD requiring replacement of exhaust v-band clamps on A36TC and B36TC Bonanzas after one failed and led to a fatal accident. Textron didn’t have any of the required clamps in stock.

The American Bonanza Society Air Safety Foundation pitched the idea that similar clamps, which have a Cessna part number, be used instead. Textron apparently has plenty of those in stock. The alternative means of compliance has been approved and the list of approved parts and models is here.
