What happened
On 5 April 2007, a Mainair Mercury, registration G-MYCV, was preparing for a local flight from an airfield near Arclid, Sandbach. Following standard pre-flight procedures, the pilot taxied the aircraft to Runway 02, noting a northwest wind of approximately 5 knots, which created a slight left-hand crosswind component.
During the takeoff roll, the pilot applied full power. However, as the aircraft reached rotation speed, it veered sharply to the right. The aircraft subsequently left the runway and struck a substantial hedge located at the side of the airstrip. Nearby pilots immediately moved to assist the occupants and called for emergency medical services. The pilot sustained minor injuries, specifically a broken rib and ankle, while the passenger remained uninjured. The aircraft suffered severe damage.
The investigation
The investigation, prompted by the pilot's accident report, focused on the aircraft's performance during the takeoff phase. Investigators examined the flight conditions and the pilot's preparation for the departure. It was established that the pilot had not adjusted for the increased weight of the aircraft due to the presence of a passenger.
Findings
- The aircraft departed the runway surface and collided with a hedge.
- The pilot lifted the aircraft off in a stalled condition.
- The pilot had failed to account for the additional weight of the passenger during the takeoff phase.
