What happened
On 12 April 1999, a Piper PA-28-161, registration G-OANC, was conducting a private flight when it experienced a runway excursion at Old Warden Aerodrome in Bedfordshire. Prior to the incident, the pilot had requested permission to land at the airfield, which serves as the home of the Shuttleworth Collection. Due to operational restrictions on the primary runway, the pilot was directed to use the grass Runway 04, which measured 613 metres in length.
Weather conditions at the time were favorable, with clear visibility of 40 km and a light wind from 310 degrees at 10 knots. The pilot performed a left-hand visual circuit at an altitude of 800 feet and subsequently touched down on the grass strip with roughly 513 metres of runway remaining. Following touchdown, the pilot retracted the flaps and applied full braking. However, the aircraft failed to decelerate sufficiently. In an attempt to avoid further hazards, the pilot steered the aircraft toward a section of longer grass, but the plane overran the area, struck a fence, crossed a ditch, and eventually came to a halt on the opposite embankment. The aircraft sustained damage beyond economic repair, but the pilot escaped without injury.
The investigation
The investigation was based on the aircraft accident report submitted by the pilot. Investigators examined the landing parameters, the runway surface, and the pilot's decision-making process regarding the available runway length. The inquiry focused on the effectiveness of the braking action and the pilot's assessment of the required stopping distance given the specific wind conditions and runway type.
