What happened
On 12 November 2005, a Robinson R22 Beta, registration G-IONE, was being prepared for departure from a private tarmacadam landing site near East Kilbride, Scotland. The pilot, operating under a private flying permit, had received clearance from Glasgow Approach to begin a local flight.
Upon lifting the helicopter into a hover, the pilot noted an uncomfortable sensation caused by what was perceived as a crosswind component originating from the left. In an attempt to correct this, the pilot lowered the aircraft back toward the ground. During this maneuver, a roll developed, causing the helicopter to land on its right-hand skid. The roll continued in the direction of the surface wind, which was recorded at 10 knots from 300 degrees, eventually bringing the aircraft to rest on its side. The pilot was able to exit the aircraft through the standard door without injury.
The investigation
The investigation focused on the environmental conditions and the aircraft's movement during the transition from hover to ground. Investigators noted that the landing site was situated near large storage sheds located upwind of the accident area. It was determined that these structures likely created an unexpected crosswind component that influenced the aircraft's stability during the initial hover.
Findings
- The aircraft sustained damage beyond economic repair.
- The primary factor in the accident was the development of a roll during the descent to the ground.
- Large storage sheds adjacent to the landing site likely generated an unexpected crosswind component.
