Approach Clearance and Wake Turbulence Warning
The local controller issued clearance for the flight to conduct a straight-in approach to Runway 20. The controller instructed the pilot to follow a large helicopter that was ahead on the approach. In addition, the controller provided a caution to the pilot that possible existing wake turbulence might be encountered due to the preceding helicopter.
Encounter with Turbulence and Go-Around Decision
While the airplane was nearing the runway threshold, the pilot experienced some turbulence. In response to this turbulence, the pilot opted to perform a go-around procedure.
Severe Turbulence During Go-Around and Loss of Control
During the go-around maneuver, the airplane encountered turbulence of a more severe nature. The pilot lost the ability to control the airplane, and the aircraft struck the runway surface. After impact, the airplane skidded along the runway until it came to a stop.
Wind Information
The pilot reported that the surface wind direction was 180 degrees, with a speed of 10 knots gusting to 15 knots.
