Aircraft involved
Probable cause & findings
The pilot’s failure to maintain stabilized lateral control during landing in gusty conditions which resulted in a dynamic rollover when the skids contacted the platform unevenly.
Factual narrative
The commercial helicopter pilot was attempting to land on a mobile landing platform in gusty conditions. As the helicopter settled down onto the helipad, the skids contacted the pad unevenly, which caused it to tilt to the right. The pilot attempted to correct and lowered the collective, but the helicopter rapidly entered a dynamic rollover and struck the ground, which resulted in substantial damage to the fuselage, mast, and main rotor blades. The pilot reported that there were no mechanical malfunctions or failures with the helicopter that would have precluded normal operation. Source: NTSB Aviation Accident Database Retrieved: 2026-02-12
