On June 25, 1995, at 1830 central daylight time, a Beech 77, N3737B, was substantially damaged during a forced landing near McAllen, Texas. The certificated flight instructor and student pilot were not injured. Visual meteorological conditions prevailed for the 14 CFR Part 91 instructional flight operated by Volare Aviation. The flight originated at Miller International Airport in McAllen, Texas, at 1800 and no flight plan was filed. The flight instructor reported, in the enclosed Pilot/Operator Report (NTSB Form 6120.1/2), that he simulated an engine failure at 2,000 feet mean sea level (MSL). The student pilot performed the emergency checklist and began to search for possible landing sites. "At approximately 400-600 feet MSL, I instructed the student to initiate a go-around. The student; however, shoved the throttle full forward, thereby depriving the engine of fuel. The engine both hesitated and sputtered...Despite my efforts, which were limited by the lack of engine thrust, the aircraft struck a fence pole and flipped over mid-air and landed on its back."
