What happened
The private certificated pilot departed from a beach adjacent to an airport for a local flight. Upon returning to the same beach location, the aircraft touched down and began its landing roll. As the airplane slowed, the pilot initiated a right turn with the intention of proceeding uphill away from the water.
During this maneuver, the main landing gear tires struck a clump of grass on the uneven surface. The impact caused the nose of the airplane to pitch forward, resulting in a nose-over incident. The aircraft sustained damage to the right wing spar, the windshield, and the vertical stabilizer.
The investigation
Examination of the accident site revealed that the primary factor contributing to the loss of control was the terrain type. The beach surface presented obstacles, specifically clumps of grass, which interfered with the main landing gear during the low-speed ground maneuver. No mechanical failures were reported prior to the incident.
Findings
The pilot's decision to execute a turn on a soft, uneven beach surface during the landing roll proved critical. The interaction between the tires and the vegetation disrupted the stability of the aircraft, leading to the nose-over. This highlights the risks associated with beach landings and subsequent ground operations in unprepared areas.
Safety message
Pilots should exercise extreme caution when operating on beaches or unprepared surfaces. Turning during the landing roll on such terrain can lead to loss of control due to uneven resistance and obstacles like vegetation or sand dunes. It is advisable to maintain a straight path until fully stopped or to ensure the surface is clear and firm before attempting any directional changes.
