What happened
On 8 July 2004, a Piper PA-18-150 Super Cub, registration G-BTBU, was conducting a private flight at Lashenden (Headcorn), Kent. The pilot was performing a straight-in approach to Runway 11, with surface winds recorded at 140º/10 kt. The approach was maintained at a speed of 60 mph using full flaps.
As the aircraft reached approximately 20 feet above the runway surface, the pilot initiated a flare. This maneuver resulted in an aerodynamic stall, causing the aircraft to impact the runway with significant force. Following the heavy touchdown, the aircraft drifted sideways across the runway surface. In an attempt to recover, the pilot applied full power to execute a go-around; however, during this process, it was noted that the left landing gear had been damaged.
The pilot subsequently reduced power, but the aircraft continued to move until it came to a stop slightly off the runway. During the excursion, the aircraft struck a marker post. There were no injuries to the pilot or the single passenger on board, and both occupants were able to exit the cockpit without assistance.
The investigation
The investigation was based on the aircraft accident report form provided by the pilot. The inquiry focused on the sequence of events during the final stages of the approach and the subsequent impact with the runway and marker post.
