Accident Sequence
During the initial climb, at approximately 150 feet above ground level, the flight instructor reduced engine power to idle to demonstrate a loss of engine power during takeoff. He then lowered the airplane's nose to gain airspeed. After about two seconds, the airplane experienced a rapid descent. The instructor advanced the throttle to full power and initiated a flare at about 20 feet above ground to arrest the sink rate. The airplane subsequently landed flat, causing all three landing gear to collapse. The aircraft skidded approximately 150 feet down the runway, resulting in substantial damage to the left wing.
Weather Conditions
Recorded data from the airport's automated weather observation station indicated that about 37 minutes before the event, the wind was from 200 degrees true at 16 knots with gusts to 23 knots. Approximately 27 minutes after the event, the wind was from 190 degrees true at 17 knots with gusts to 27 knots. The airplane had landed on runway 21R.
Aircraft Inspection
According to the flight instructor, there were no preimpact mechanical failures or malfunctions with the airframe or engine that would have prevented normal operation.
