Bonanza AD Fix Uses Cessna Part

Gemini Sparkle

Key Takeaways:

  • The FAA issued an Airworthiness Directive (AD) for A36TC and B36TC Bonanzas requiring exhaust v-band clamp replacement, grounding some aircraft due to a fatal accident.
  • Textron, the manufacturer, did not have the required replacement clamps in stock, preventing compliance with the AD.
  • The American Bonanza Society Air Safety Foundation proposed using similar exhaust clamps with a Cessna part number as an alternative.
  • The FAA approved this alternative means of compliance (AMOC), allowing owners to use the readily available Cessna clamps to comply with the AD and get their aircraft back in the air.

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.
