Thursday, October 4, 2007 14:50 AKD

NTSB Narrative Summary Released at Completion of Accident

The flight instructor/mentor pilot for a federal agency was demonstrating off-airport landing techniques to a commercial federal pilot at a remote off-airport site during a public use training flight. The flight instructor was flying the airplane, and was attempting to do a touch and go landing on a gravel bar when the left wing struck a clump of vegetation. The flight instructor completed the touch and go, and returned the airplane to its base, where it was found that a wing rib would have to be replaced. The operator noted that there were no preaccident mechanical problems with the airplane.

NTSB Probable Cause Narrative

The flight instructor's failure to maintain clearance from high vegetation during the off-airport landing.
