What happened
On the morning of 4 March 2013, a Beechcraft Premier 1A, registered VP-CAZ, prepared for a short private flight from Annemasse aerodrome to Geneva airport. The flight was scheduled to last approximately five minutes. At approximately 07:28, air traffic control provided departure clearance for an initial climb to 6,000 feet. During the pre-taxiing procedures, the pilot confirmed the configuration of the flaps at 10 degrees and activated the engine anti-ice system.
The takeoff roll commenced at 07:38:03. Shortly after liftoff at 07:38:37, the aircraft exhibited a high pitch-up attitude accompanied by a low rate of climb. Within seconds, the cockpit voice recorder captured multiple GPWS bank angle warnings and stall warnings. Radar tracking indicated the aircraft was at an altitude of roughly 80 feet during these maneuvers. Witnesses observed the aircraft banking sharply to both the left and right sides.
At 07:38:52, the main landing gear impacted the roof of a residence, after which the aircraft struck the ground. The impact caused the separation of the left wing and all three landing gears. The wreckage slid approximately 100 meters through a garden, striking a wall, a shed, and trees, eventually catching fire. The accident resulted in two fatalities and one serious injury.
