What happened
The pilot was conducting a takeoff from a sandy beach environment. Conditions included a 90-degree crosswind estimated at 15 knots, with gusts reaching up to 30 knots. During the initial phase of the roll, a wind gust caused the aircraft's nose to weathercock sharply into the wind. By the time the pilot reduced engine power in response, the aircraft had already entered loose sand. This interaction resulted in the right main landing gear leg being pulled from its mounting box. The subsequent impact with the surface bent the right wing.
The investigation
Examination of the accident site and aircraft revealed significant structural damage consistent with ground contact during an aborted or failed takeoff attempt. The primary mechanical failure involved the separation of the right main landing gear assembly from the landing gear box. Additionally, the airframe sustained deformation to the right wing structure due to the force of the impact with the sandy terrain.
Findings
The sequence of events was driven by environmental factors and surface conditions. The loose sand on the beach likely reduced traction and stability during the critical takeoff roll. The crosswind component, combined with gusts, created a weathercocking moment that the pilot could not fully counteract before the aircraft encountered the unstable surface. The loss of the right main gear leg was a direct result of the forces exerted when the aircraft settled into the sand at an abnormal attitude.
Safety message
Operations from unprepared surfaces such as sandy beaches require careful assessment of wind conditions and surface stability. Pilots should be aware that loose substrates can compromise directional control and landing gear integrity, especially during high-power phases like takeoff. Understanding the limits of crosswind capability on soft surfaces is essential for preventing similar incidents.
