Incident Overview
A student pilot, under the supervision of an instructor, was conducting a simulated engine-out landing on a turf airstrip. After landing to the east, the instructor directed the student to perform a takeoff to the west using soft field techniques. The student had never practiced an actual or simulated soft field takeoff before.
Sequence of Events
While the aircraft idled at the east end of the 2,640-foot airstrip, the instructor explained the soft field takeoff procedures. The student then initiated the takeoff roll to the west. During the roll, the airspeed stabilized at approximately 45 MPH. The instructor advised the student that the aircraft would accelerate once it lifted off.
After liftoff, the student maintained a climb rate that kept the airspeed at 45 MPH. About halfway down the airstrip, after passing tree-top level, the aircraft stopped climbing. At that point, the instructor took control and lowered the nose in an attempt to gain airspeed. To accelerate, the instructor had to allow the aircraft to descend back toward the runway surface.
As the aircraft neared the surface, the instructor became uncertain whether it could clear the trees at the west end of the airstrip. He therefore aborted the takeoff and attempted to land on the remaining runway. During this attempt, the aircraft dropped from approximately 20 feet above the surface. The nose gear bent back, the nose dug into the soft terrain, and the aircraft flipped over onto its back.
Outcome
The aircraft came to rest inverted on the turf airstrip. The flight was a training exercise involving a simulated engine-out landing followed by a soft field takeoff. No further details are available from the source.
