Accident Summary
On July 30, 2025, at 11:28 eastern daylight time, a Cessna 172S, registered as N121CW, was substantially damaged during an accident near Kissimmee, Florida. The aircraft was conducting a Part 91 instructional flight with a private pilot receiving commercial instruction from a flight instructor. Both occupants reported no injuries.
Flight and Engine Failure
Preflight checks indicated sufficient fuel and engine oil. The taxi, runup, and takeoff from Kissimmee Gateway Airport (ISM) were normal. While climbing through 1,900 feet mean sea level, both pilots felt engine vibrations, followed by a loud bang. The windshield was immediately covered with engine oil, significantly reducing forward visibility.
Forced Landing
The flight instructor assumed control and initially turned back toward ISM, but determined the aircraft lacked sufficient altitude to reach the airport. A forced landing on a road was initiated. The pilot receiving instruction looked out the side window, while the instructor used peripheral vision to guide the airplane onto the road. During the landing, the airplane struck a car and came to rest on the road shoulder.
Postaccident Examination
A Federal Aviation Administration examination revealed substantial damage to the fuselage. The engine had experienced a catastrophic internal failure: a large portion of the top crankcase had separated from the rest of the crankcase, and the No. 2 connecting rod had released from its crankshaft journal.
Further Investigation
The wreckage was retained for additional examination to determine the precise cause of the engine failure.
