Probable cause

The student pilot's misjudgement of distance and altitude, and the instructor's inadequate supervision.

Analysis

The glider-rated student pilot was receiving dual transition instruction and was conducting touch and go landings. On the fourth approach, the instructor 'felt the airplane was low, but not dangerously so,' and told the student to add power. The instructor saw the orange marker balls on the powerlines but felt that the airplane had cleared them. The airplane severed two powerlines, landed short of the runway, struck a dirt bank and overturned. Runway 9 equipped with low intensity runway lights; does not have a VASI.
