This incident involved a Cirrus SF50 Vision Jet shortly after takeoff in Mount Comfort, Indiana. The flight was intended to be a short repositioning trip under IFR conditions, with a relatively low cloud ceiling. The pilot, highly experienced with over 12,000 flight hours, performed a normal takeoff and engaged the autopilot and autothrottle at around 800 feet above ground level.
Within moments, the situation changed dramatically. The aircraft suddenly pitched up to a steep nose-high attitude while the engine power dropped to idle. This combination is extremely dangerous because it rapidly reduces airspeed and can lead to an aerodynamic stall. At the same time, cockpit warnings appeared, and the pilot attempted to override the automation. However, the system did not respond as expected—the controls resisted, and the throttle repeatedly returned to idle despite the pilot’s inputs.
The root of the problem was a malfunction in the aircraft’s CAPS, or Cirrus Airframe Parachute System. This system is designed as an emergency safety feature that automatically stabilizes the aircraft before deploying a parachute. When activated, it commands a nose-up attitude and reduces engine power to prepare for descent under canopy. In this case, the system activated without any input from the pilot.
Investigators later discovered that corrosion within the CAPS activation system generated a false signal indicating that the parachute had been deployed. This caused the aircraft’s automation to enter CAPS autopilot mode at a very low altitude, around 226 feet above the ground. As a result, the aircraft behaved exactly as it would during a real emergency parachute sequence, even though no such command had been given.
The pilot’s delay in fully disconnecting the automation—about 26 seconds—proved critical. During that time, the aircraft’s airspeed dropped significantly, bringing it close to stall conditions. Recognizing the severity of the situation and the loss of control, the pilot made the decisive choice to manually deploy the parachute.
Once deployed, the parachute stabilized the aircraft and allowed it to descend safely. The jet landed near a retention pond and was heavily damaged, but the pilot survived without any injuries.
The National Transportation Safety Board determined that the primary cause of the incident was the uncommanded activation of the CAPS autopilot mode due to corrosion in the system. A contributing factor was the pilot’s delayed recognition of the mode and the time taken to disengage it.
Following the incident, Cirrus Aircraft implemented design changes to the CAPS circuitry to prevent false activation signals in the future. This case highlights how even minor technical faults can trigger serious in-flight emergencies, and it underscores the importance of both system reliability and pilot response in ensuring flight safety.
