What happened
On 10 January 1998, a Beagle A.61 Series 2, registration G-AYDX, was performing a private flight at Aston Down Airfield in Gloucestershire. Having just completed a glider aerotow to 3,000 feet, the pilot began a descent toward the grass Runway 21. The weather conditions were clear, with visibility of 12 km and a light wind from 180 degrees at 10 to 12 knots.
As the aircraft approached the landing area, the pilot noted a glider that had previously landed positioned to the left of the touchdown zone. While crossing a public road on short finals at 300 feet, the pilot's attention was drawn to this glider. This distraction led to a delay of approximately two to three seconds before the pilot reduced the engine to idle power. Consequently, the aircraft touched down further down the runway than intended.
Because the boundary between the landing strip and the adjacent cultivated farmland was difficult to distinguish, the pilot was unaware of the limited distance remaining. Upon applying the heel brakes, the aircraft overran the end of the runway at roughly 10 to 15 knots. The wheels sank into the soft soil of a winter wheat field, and despite the pilot's attempt to pull the stick rearward, the aircraft pitched onto its back. There were no injuries to the pilot, though the aircraft sustained substantial damage to the wing, propeller, cowling, fin, and rudder.
The investigation
The investigation examined the sequence of events leading to the overrun and the pilot's decision-making during the landing phase. Investigators reviewed the pilot's flight experience, noting significant time spent in gliders, and analyzed the environmental factors, such as the indistinct transition between the runway and the farmland.
Findings
- The pilot's attention was diverted by the presence of a glider on the left side of the landing zone.
- This distraction caused a delay in reducing power to idle, resulting in a long touchdown.
- The pilot did not realize the aircraft was approaching the end of the usable landing surface.
- The pilot did not attempt a go-around because his long-term experience in gliders, where go-arounds are not an option, influenced his subconscious reaction during the landing phase.
