NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The instructor pilot and student pilot were preparing for the student pilot's private pilot check ride. Both pilot's remember practicing maneuvers for 40 minutes before returning to the airport to practice soft and short field takeoff's and landings. On the landing preceding the accident takeoff the instructor simulated an engine failure and the student landed without any difficulty. On the accident takeoff the student pilot raised the flaps and the instructor simultaneously leaned the mixture to simulate a power loss. The instructor took over on the controls when the student did not recognize the situation. He attempted a restart of the engine, while the student flew the aircraft to an open field. While attempting to restart the engine the instructor observed a power line and instructed the student to fly underneath the power line. Both pilot's stated that on the last attempt to restart the engine, it started. They both looked up and saw power lines and attempted to maneuver the aircraft underneath the power lines. The student pilot stated that his instructor did not indicate to him that he was going to simulate an engine failure.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The instructor pilot's inadequate in-flight planning/decision and subsequent inadequate supervision of the situation to simulate an engine failure on takeoff, as well as both pilot's not maintaining a visual lookout. A related factor was the diverted attention of both the instructor and student pilot's.
