AAIB investigation to Pioneer 300, G-CDSD: Substantially damaged due to a runway excursion on landing at Wallis International Airstrip, 26 North Side, Thorney, Peterborough, Cambridgeshire, 9 June 2020. The AAIB Final Report was published on 12 November 2020, and the following is an excerpt from it...

"The pilot flew from a private farm strip east of Alconbury Airfield to Wallis International Airstrip near Whittlesey. The weather was good; CAVOK and light winds. The transit was uneventful and, on arrival, the pilot flew a normal approach to Runway 08, but with a planned go-around to check the runway before landing.

The high trees near the Runway 08 threshold were noted, as was the direction of the wind, which was from the east and down the runway. A second approach was made but, due to other traffic, another go-around was flown.

The third approach was commenced with full flap selected on finals, and with an approach speed of 65 Knots IAS reducing to 50-55 Knots IAS over the threshold. The need to ensure a safe margin over the trees caused the aircraft to touch down approximately half-way along the 770 metre grass strip where it went over a bump, causing it to bounce and land back on the left side of the runway.

The pilot applied the wheel brakes but the left wing became caught in long grass and the aircraft yawed to the left, veering off the runway and striking several concrete posts and barbed wire fencing. It dropped into a water filled dyke on the north side of the runway and the canopy detached, with the aircraft remaining upright.

The pilot and passenger were uninjured and were able to vacate the aircraft unassisted. The pilot considered that a lack of experience of landing on a farm strip with obstacles, such as the trees close to the threshold, had caused the aircraft to touch down further into the runway than expected. Encountering the bump in the runway surface and touching down close to the left edge of the runway led to the left wing entering the long grass".

Damage sustained to airframe: Per the above AAIB report "Damage to the engine and airframe"
