On April 17, 2004, about 0845 central daylight time, a Beech C23, N6715X, operated by the Flight Center at Service Aviation Inc., sustained substantial damage on impact with terrain when the airplane exited the runway during a go-around at the Lake in the Hills Airport, near Lake in the Hills, Illinois. The instructional flight was operating under 14 CFR Part 91. Visual meteorological conditions prevailed at the time of the accident. No flight plan was on file. The instructor pilot and student pilot reported no injuries. The flight departed from Palwaukee Municipal Airport (PWK), near Wheeling, Illinois, about 0720. The certified flight instructor's accident report stated: The aircraft turned final and flew a slightly low and fast approach to the runway. The aircraft touched down flat on the runway and because of the excess speed the aircraft bounced into the air a considerable amount. At this point a go around was initiated. As the power was advanced the aircraft began a left turn and drifted off the runway. At this point the instructor called for complete control of the aircraft and returned to wings level pitch attitude, however despite the application of full power the aircraft refused to climb and touched down right main first on the grass to the north side of the runway. The aircraft then swung nose right shearing off the nose gear and left main gear causing the propeller to strike the ground. The aircraft came to rest in the grass to the north of runway 8 about halfway down the runway, and facing the centerline of the runway. The pilot reported no mechanical malfunctions associated with the airplane in reference to the flight. A Federal Aviation Administration Inspector performed an examination of the wreckage. The examination revealed that the flight controls were operational and correct and that the engine controls were operational.
