Following a well-publicized ground fire on December 27, 2019, beginning in the cabin of a Cirrus Vision Jet in Santa Monica, the company released a service bulletin (SBA5X-23-03) on February 7 to correct the problem, which was traced to a potential malfunction of the audio interface circuit card that could have resulted in the overheating of the cards. Cirrus also released a customer communication missive to outline the company’s steps to resolve the problem.
FAA Releases AD on Cirrus Vision Jet
Key Takeaways:
- A December 2019 ground fire on a Cirrus Vision Jet was traced to overheating audio interface circuit cards.
- Cirrus issued a service bulletin in February 2020 to correct the problem, which the FAA then mandated with an emergency Airworthiness Directive (AD 2020-03-05).
- The AD requires the removal of these cards before flight, which disables non-essential 1/8-inch audio jacks but leaves aviation headset functions unaffected.
- At the time of the AD's issuance, approximately 97% of the over 170-aircraft fleet had already complied with the fix.
