On February 14, 1994, about 1745 central standard time, a Cessna 150L, N10797, registered to Romac, Inc., collided with a pole while making a forced landing on a road near Ocean Springs, Mississippi, while on a 14 CFR Part 91, instructional flight. Visual meteorological conditions prevailed at the time and no flight plan was filed. The aircraft received substantial damage and the commercial-rated flight instructor and student pilot were not injured. The flight originated at Ocean Springs, Mississippi, on February 14, 1994, at 1730. The flight instructor stated they had just completed a second power off stall and climbed back to the originating altitude of 2,500 feet when the engine failed suddenly. While attempting a forced landing on a road the left wing contacted a power pole and the aircraft descended uncontrolled and came to rest in a marsh adjacent to the road. Postcrash examination of the aircraft and engine by FAA inspectors indicated the airframe and engine fuel systems contained uncontaminated fuel. The engine was placed on a test stand and operated to full power with no malfunctions. Review of carburetor icing probability charts indicated the aircraft was operating in conditions conducive to serious icing at cruise power.
