On July 25, 1998, at 1300 eastern daylight time (edt), a Cessna 152, N623AF, operated by a commercial pilot, sustained substantial damage, when during takeoff the airplane ran off of the end of the runway at Greenville Municipal Airport, Greenville, Michigan. Visual meteorological conditions prevailed at the time of the accident. The instructional flight was being conducted under 14 CFR Part 91. There was no flight plan on file. The instructor pilot and dual student on board reported no injuries. The cross-country flight was originating at Greenville, Michigan. In his written statement, the instructor pilot said that the student pilot was making the takeoff on runway 18. The Instructor pilot said, "At the intersection of runway 27 (the runway which crosses runway 18 at the mid-point), we were at 40 knots indicated airspeed (KIAS). After passing the intersection, the airplane started to lift off, but returned to the grass. The airspeed indicator again read 40 KIAS. The instructor pilot told the student to abort the takeoff. The instructor pilot said that he took control of the airplane just as they passed the end of the runway. The airplane crossed one ditch and stopped when it hit a second ditch. A Federal Aviation Administration (FAA) inspector examined the airplane at the Greenville Municipal Airport. The airplane's nose wheel strut was broken aft. One of the two propeller blades was bent aft. The airplane's right wing tip was crushed aft and inward. The right wing's forward spar was bent aft. Flight control continuity was confirmed. Examination of the airplane's engine, engine controls, brakes and other airplane systems revealed no anomalies.
