What happened
On 8 August 2010, a Robinson R22 Beta, registration G-NWDC, was involved in an accident during a training flight at Londonderry Eglinton Airfield. Following a successful dual-instruction circuit, the instructor decided to allow the student pilot to proceed with a solo session. After the instructor vacated the aircraft, the student performed two takeoff and landing sequences on a specific area of the main runway.
During a turn into the wind, the left skid of the helicopter unexpectedly made contact with the ground. This contact destabilised the aircraft, leading to a loss of control. The helicopter subsequently struck the ground and rolled onto its side, resulting in substantial damage to the rotor blades, tail boom, and landing gear. The student pilot, who had 82 total flying hours, suffered minor injuries.
The investigation
Investigators reviewed the accident report submitted by the pilot and examined the circumstances of the flight. The investigation focused on the transition from the takeoff sequence to the turning maneuver. It was noted that the student had previously completed a satisfactory circuit with an instructor, which led to the decision to attempt the solo exercise.
Findings
- The accident was caused by the left skid touching the ground during a turn into the wind.
- The initial ground contact may have been a result of the helicopter sinking due to insufficient power being applied during a left pedal turn into the wind.
- The contact with the ground destabilised the aircraft, making it impossible for the student to maintain control.
