Accident
On 19 May 2017 at approximately 1740 UTC, a Piper PA-24-250 Comanche, registration N673SA, experienced a landing gear collapse during a landing attempt at Firs Farm Airfield, Newbury, Berkshire. The aircraft was on a private flight with one pilot and one passenger; neither was injured.
Flight Details
The pilot reported that the approach was made during a heavy rain shower. The approach speed was high, and the aircraft touched down with approximately 400 meters of runway remaining. According to aircraft performance tables, the corrected landing distance for a wet grass surface using short field technique (which employs maximum braking) is 309 meters. The pilot applied hard braking but encountered wheel locking, requiring a reduction in brake pressure to prevent a skid. As a result, the landing distance required was significantly increased. Without short field technique, the manufacturer's documents indicate that landing distance could be doubled.
At the end of the runway, the area beyond was planted with crops. To avoid overrunning into the crops, the pilot attempted a turn while the aircraft was still at a higher than normal speed. During the turn, the aircraft skidded and slid off the operating surface into the crops, causing the left landing gear leg to collapse. Both occupants exited the aircraft without injury.
The pilot noted that given the high speed and incorrect touchdown point, a go-around should have been executed. The CAA Safety Sense Leaflet 7c, which provides information on general aviation performance planning, was referenced in the report.
