What happened
On August 5, 2024, a Cessna 750, registration N750GB, was involved in an accident near Jamestown, New York. The aircraft, operated by Access Stripe, Inc. under Part 91 regulations, departed Chautauqua County Dunkirk Airport (DKK) en route to Fort Lauderdale Executive Airport (FXE) to collect parts and a mechanic.
During the initial climb, the crew encountered issues that led to an emergency descent. The copilot reported smelling electrical smoke at approximately 5,000 feet, an odor that both pilots detected by 8,000 feet. As the aircraft descended through 10,000 feet, the copilot noted the pitch trim was trimming down, causing the aircraft to accelerate well beyond 250 knots. This was accompanied by the illumination of the Master Caution and various Crew Alerting System (CAS) messages. The copilot also noted that Communication 2 had failed and the Garmin 5000 display showed red error marks.
Air traffic control (ATC) lost contact with the flight crew after providing an instrument flight rules clearance. The aircraft eventually displayed an emergency transponder code (7700) while descending through 7,800 feet. The last communication received by the Buffalo controller was the crew stating they were about to land at Jamestown Airport (JHW).
Track data showed the aircraft performed a 270-degree descending, decelerating left turn to align with runway 25. The airplane impacted the ground in a flat attitude approximately 200 feet before the approach end of runway 25. The aircraft continued along the runway centerline, exited the left side of the runway, and came to rest about 225 feet from the left edge.
In the accident, the pilot sustained 1 serious injury and the copilot sustained 1 minor injury. There were 0 fatalities.
