What happened
On 7 April 2013, a Mainair Blade 912, registration G-BZWB, was engaged in a training flight at Caernarfon Airport in North Wales. The aircraft, operated by a student pilot, was performing circuit practice maneuvers. During the takeoff roll on Runway 08, the pilot reduced engine power shortly after leaving the runway surface. This reduction in power led to a loss of altitude and caused the right wing to drop. Although the pilot attempted to recover by applying full power, the aircraft continued to descend and struck the ground on its right side. The impact resulted in severe damage to the trike and wing, though the pilot, who was wearing a helmet and lap strap, escaped without injury.
The investigation
Investigators examined the circumstances surrounding the loss of control during the takeoff phase. The investigation focused on the pilot's actions regarding engine power management and the subsequent aerodynamic response of the aircraft. The pilot provided a statement indicating that the descent was initiated by the deliberate reduction of power following takeoff.
Findings
- The accident was primarily caused by an excessive reduction of engine power immediately after takeoff.
- This power reduction induced a nose-down attitude and a significant wing drop.
- The pilot's attempt to arrest the descent with full power was insufficient to prevent the aircraft from striking the ground.
