History of the Flight
The pilot, accompanied by his wife and two other relatives, conducted a two-hour sight-seeing flight in the Fort William area. Upon returning to Strathallan Airport, the pilot used his GPS receiver to confirm that local winds were light and variable and that the circuit was clear. The aircraft approached Runway 10, a 600-meter long grass surface, on a long final approach.
Landing and Overshoot
The aircraft touched down approximately 100 meters along the runway. Due to a combination of the aircraft's high weight and a light headwind, it did not decelerate as anticipated. The pilot raised the flaps and applied hard braking, but the aircraft continued further than expected. Concerned by the approaching boundary fence, the pilot re-applied power to attempt a go-around; however, insufficient runway distance remained. The aircraft passed through the boundary fence, after which the engine was shut down.
Damage and Aftermath
The aircraft continued across an adjacent field and down a slope, coming to rest after colliding with a line of trees. All four occupants were uninjured and vacated the aircraft normally. The nose landing gear spat and the inner portions of the wing leading edges, where they struck the trees, were damaged. There was no fire. The pilot, who typically operated the aircraft solo, attributed the accident to the high weight and lack of headwind, which resulted in more momentum than expected and increased groundspeed on touchdown.
