Wednesday, August 16, 2006 11:20 CDT

NTSB Narrative Summary Released at Completion of Accident

The airplane was damaged when it struck the ground during an attempted go-around following a simulated engine failure. The flight instructor stated that he simulated an engine failure while in the traffic pattern and his student performed the engine failure checklist while continuing in the traffic pattern. He stated that it became apparent that they were going to be short of the runway and he called for a go-around. He stated that his student then retracted the flaps from full flaps to no flaps prior to applying engine power. He stated that he then applied full power, but was unable to arrest the high sink rate. The airplane subsequently impacted the ground and bounced back into the air. The flight instructor then landed the airplane on the runway.

NTSB Probable Cause Narrative

The dual student's premature retraction of the flaps during the attempted go-around which resulted in the impact with the ground. The flight instructor's delay in calling for the go-around was an additional cause.
