What happened
On 22 June 2001, an Avid Speedwing, registration G-BTRC, was performing a private flight near Brighton. Following a local flight, the pilot attempted a straight-in approach to the west for a touch-and-go landing on a grass farm strip at Trueleigh Farm. The wind was 7 knots and variable, and the pilot determined the tailwind component was acceptable for the landing.
After completing a successful touch-and-go, the aircraft began its initial climb. However, the engine began running roughly and suffered a loss of power. At an altitude of approximately 50 to 100 feet, the pilot elected to land in an adjacent field. While the aircraft initially cleared a line of trees, it could not be stopped before striking a second line of trees. The right wing struck the trees first, causing the aircraft to spin. There were no injuries to the pilot or the passenger, though the aircraft sustained substantial damage. Both occupants were able to evacuate the aircraft safely using four-point harnesses.
The investigation
The investigation examined the engine performance and environmental conditions. Although the pilot initially suspected carburettor icing due to the descent from 2,000 feet and the prevailing temperature and dew point, the aircraft's carburettor utilizes pre-warmed air from the engine cowling. This specific system does not have a documented history of icing issues. Subsequent inspections of the engine and propeller by the pilot the following day revealed no obvious mechanical faults, as the engine appeared to return to normal operation after an initial single-cylinder run.
Findings
- The aircraft experienced a loss of engine power during the climb phase following a touch-and-go maneuver.
- The pilot's decision to land in an adjoining field was made at a very low altitude (50 to 100 feet).
- The impact with the trees was caused by the aircraft's inability to stop before reaching the tree line.
