What happened
On 22 September 2012, a Jodel D112, registration G-BHNL, was performing a private flight when it experienced a runway excursion at the MOD Airfield at Thorney Island, Hampshire. During the landing on Runway 01, the pilot employed a wheel landing technique to manage a 9-knot crosswind from 90 degrees. While the pilot initially maintained directional control, the aircraft began to swing toward the wind as it decelerated and the tail lowered. In an attempt to correct the direction, the pilot applied left rudder, which triggered an opposite swing and a subsequent veer to the left. This resulted in an uncontrollable oscillation that led the aircraft to collide with a wooden post and fencing located on the left side of the concrete runway. The impact caused substantial damage to the wings, propeller, and cowling. The pilot, who was uninjured, secured the aircraft before exiting the runway.
The investigation
The investigation was based on the aircraft accident report submitted by the pilot. Investigators examined the landing technique used and the environmental conditions at the time of the accident. It was established that the pilot was using a wheel landing method, which involves touching down with the aircraft in a level attitude to maintain higher approach speeds in crosswind conditions. The investigation also reviewed the sequence of control inputs, specifically the use of left rudder, which contributed to the loss of directional stability as the aircraft slowed.
