Ferdinand, IN, USA
N3002X
CESSNA 150F
The private pilot and passenger were on a cross-country personal flight at 2,500 ft mean sea level and were about 15 miles north of their destination airport. They began the descent, and during the descent, the engine sputtered, followed by a total loss of power. The pilot attempted to troubleshoot the loss of power but was unsuccessful; however, he did not apply carburetor heat during the troubleshooting. Subsequently, the pilot made a forced landing to a parking lot. During the landing roll, the airplane impacted an embankment and nosed over. Postaccident examination of the airplane revealed that fuel was present in the fuel tanks and the fuel lines to the carburetor. Examination revealed no evidence of any preimpact mechanical failures or malfunctions that would have precluded normal operation. Weather conditions at the time of the accident were conducive to the accumulation of serious carburetor icing at glide power settings. It is likely that, during the descent, carburetor ice accumulated due to the pilot's failure to apply carburetor heat, which resulted in the loss of engine power.
On June 18, 2018, about 2245 eastern daylight time, a Cessna 150F airplane, N3002X, made a forced landing in a parking lot then nosed over in an embankment. The private rated pilot sustained serious injuries and the passenger sustained minor injuries. The airplane sustained substantial damage. The airplane was registered to Gas Publishing LLC and operated by the pilot under the provisions of Title 14 Code of Federal Regulations Part 91 as a personal flight. Night visual meteorological conditions prevailed at the time of the accident and no flight plan had been filed. The flight departed Central Wisconsin Airport (CWA), Mosinee, Wisconsin, about 1700 central daylight time and was en route to Perry County Municipal Airport (TEL), Tell City, Indiana. After the accident, the pilot reported that before the flight he had filled the long range fuel tanks with 35 gallons of fuel. He stated that about 15 miles north of TEL at 2,500 ft mean seal level, the engine sputtered. The pilot was unable to troubleshoot the engine issue and the engine experienced a total loss of power. He made a forced landing to a paved parking lot between two rows of parked semi-trailers. The airplane landed hard and nosed over when it impacted an embankment (figure 1). The pilot and passenger exited the airplane under their own power. The pilot reported that there were not mechanical malfunctions or failures with the airplane.

The pilot added that he tried to make it to Huntingburg Airport (HNB), Huntingburg, Indiana, but did not have enough altitude so he made an off-field landing. During the final approach to the paved area the pilot saw power lines and a utility pole; he stated that he banked the airplane to avoid the power lines and pole. The FAA inspector examined the engine and did not find any anomalies that would have precluded normal operation. There was a smell of aviation fuel at the accident site. An unmeasured amount of fuel remained in the fuel tanks during the recovery of the airplane. Also, fuel was present in the fuel lines to the carburetor. The carburetor icing probability chart included in Federal Aviation Administration Special Airworthiness Information Bulletin No. CE-09-35, Carburetor Icing Prevention, indicated that the airplane was operating in an area that was associated with a serious risk of carburetor ice accumulation at glide power settings (figure 2).
