What happened
During a takeoff from Runway 27 at Bute Airstrip, the pilot of a CZAW SportCruiser, registration G-EWZZ, reported a loss of engine power. This loss of thrust prevented the aircraft from achieving the necessary climb gradient. Because the terrain surrounding the airfield was deemed unsuitable for an emergency landing, the pilot attempted to maneuver the aircraft back toward the runway. During this attempt, the aircraft struck the ground. The impact caused the aircraft to overturn in a ditch, subsequently leading to an onboard fire.
As a result of the accident, the pilot and a passenger both sustained serious burns. While the pilot survived, the passenger later succumbed to their injuries.
The investigation
The investigation focused on the sequence of events leading to the impact and the performance of the aircraft's safety equipment. It was noted that the aircraft was equipped with a ballistic parachute recovery system; however, this system was not deployed during the flight. The inquiry also examined the implications of such systems in the aftermath of an accident, noting that they can introduce specific hazards for both the occupants of the aircraft and emergency personnel responding to the scene.
Findings
- The primary cause of the accident was the loss of engine power shortly after takeoff.
- The aircraft was unable to maintain altitude or climb due to the lack of thrust.
- The terrain surrounding Bute Airstrip prevented a safe landing away from the runway.
- The ballistic parachute recovery system remained inactive throughout the incident.
Safety action
Following the investigation, seven safety recommendations were issued. These measures are intended to mitigate the risks posed to individuals, including first responders, following accidents involving aircraft fitted with ballistic parachute recovery systems.
