Incident Overview
A flight instructor and his pilot student were conducting a pre-takeoff runup while the aircraft faced runway 30. The wind was reported from 280 degrees at 21 knots with gusts to 35 knots.
Sequence of Events
The instructor stated that during the runup, the airplane pivoted left on the nose gear tire. Subsequently, the right wing lifted into the air. As the wing rose, the propeller made contact with the ground. Shortly thereafter, according to the instructor, the airplane "went up on its spinner and over on its back."
