At 1727 Eastern time, the airplane was substantially damaged during a forced landing following a loss of engine power. The Flight Instructor and the Student pilot sustained minor injuries. Visual conditions prevailed. The instructor later said that the airplane was in cruise flight at 1500 feet when the engine lost power. At that time, he noted that the fuel quantity indicator for the right tank showed one-quarter full, and the left tank indicator showed three-quarters full. The engine would not restart, but when the primer was pumped, the engine produced short bursts of power. The instructor gave control of the primer to the student, and used the short bursts of power to help the airplane reach the field he had selected as a forced landing area. The airplane touched down, then overran the field and struck trees.
