FAA Grounds All Cirrus Vision Jets over Angle of Attack Issues
Key Takeaways:
- The FAA issued an emergency airworthiness directive (AD) grounding the entire Cirrus SF50 Vision Jet fleet.
- The grounding was prompted by multiple incidents of the aircraft's stall warning and protection systems (SWPS) or electronic stability and protection (ESP) engaging inappropriately.
- The AD requires immediate maintenance or replacement of faulty angle of attack (AOA) indicators, which are linked to the erroneous system engagements.
- The FAA emphasized the condition presents an immediate and potentially fatal danger due to the risk of uncommanded pitch-down maneuvers.
