BELL UH 1H
The pilot reported that, while hovering the helicopter to park between three stationary helicopters, the ground crew gave him the signal for a 180° "pedal turn." As the helicopter was about to touch down, he felt a shudder in the airframe. He then immediately rolled the throttle closed and completed an emergency shutdown. Postaccident examination revealed that the tail rotor blades struck the main blades of a stationary helicopter, which likely caused the shudder felt by the pilot. The helicopter sustained substantial damage to the tail rotor and main rotor systems. The pilot reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
