Aircraft involved
Probable cause & findings
The pilot’s failure to ensure that the helicopter was properly positioned over a dolly before attempting to land on it, which resulted in a rollover.
Factual narrative
According to the pilot, he was attempting to land the helicopter on a portable dolly, and he was following a marshaller to land on the dolly. As he lowered the collective, the helicopter’s skids fell off the back of the dolly, and the tail rotor struck the ground. The helicopter subsequently rolled over on its left side resulting in substantial damage to the main rotor and tail rotor systems. The pilot added that there were no mechanical issues with the helicopter. Source: NTSB Aviation Accident Database Retrieved: 2026-02-12
