The NTSB's narrative final · quoted from the NTSB record
According to the pilot, while hover taxiing downwind, a gust of wind pushed the tail 90 degrees to the left, which forced the helicopter to descend into the pavement. The pilot reported that the front and rear crossover tubes between the left and right landing skid assemblies were bent, and that the tail cone was wrinkled at the fuselage attach points.
