Analysis

On March 3, 1986 at approximately 1715 MST, an experimental miller, sievers special, struck the ground during takeoff at the Gillette-campbell county airport, Gillette, Wyoming. The pilot stated that just after takeoff on runway 34, the aircraft appeared to lose a little power at approximately 500 feet as he was starting a left turn. The aircraft had insufficient airspeed and stalled. The pilot indicated the airspeed was indicating about 60 mph. He attempted recovery by pushing the control stick forward and headed for a field west of the runway. No reason for the power loss could be determined.
