What happened
On 31 July 2020, a Cirrus SR2 after registration N8163P, operated for a private flight, was approaching Cotswold (Kemble) Airport for landing. While on final approach for Runway 08, the pilot was informed that the runway was occupied by another aircraft. Because the preceding aircraft did not vacate the runway at the expected intersection, the pilot delayed the touchdown, waiting for permission to land at his own discretion.
As the aircraft reached the first touchdown zone markings, the left wing dropped and struck the runway surface. The aircraft subsequently landed on the grass, traveling at an angle of approximately 45 degrees to the left of the runway heading. During the excursion, the aircraft collided with a parked Piper PA-30, registration G-ATXD, on the North Apron. The impact caused the left wing of N8163P to strike the right wing of the stationary aircraft, causing the Cirrus SR22 to slew sideways across the apron. There were no injuries to the pilot or the two passengers on board.
The investigation
The AAIB examined the flight sequence, aircraft damage, and meteorological conditions. CCTV footage from the airfield showed the aircraft's attitude appeared normal as it crossed the threshold, but confirmed the left wing made contact with the runway edge before the aircraft settled on the grass.
Investigators analyzed the wind conditions, noting that while the pilot believed a gust caused the veer, the windsock and CCTV evidence indicated a relatively steady 15-knot crosswind without significant gusts. The investigation also reviewed the pilot's attempt to execute a go-around while the aircraft was already on the ground. The high ambient temperature of 29°C and the presence of a tailwind were noted as factors that may have impacted the aircraft's performance during this maneuver.
Findings
- The loss of control was primarily caused by the pilot delaying the touchdown while monitoring the runway occupancy of the preceding aircraft.
- The aircraft's handling at low speeds, while attempting to counteract the crosswind, likely led to the wing drop.
- The decision to initiate a go-around while the aircraft was already on the ground increased the risk of collision and the potential for damage to third parties.
- The aircraft sustained significant damage, including a broken right main landing gear, propeller damage, and wing abrasions, while the parked G-ATXD suffered severe right-wing damage and a fuel leak.
