Union Mills, NC, USA
N91SP
CESSNA 172
The commercial pilot was practicing landing approaches to a private airstrip that he was constructing. According to the pilot, while flying about treetop height with full flaps deployed, he added full power to initiate a climb; the engine "sputtered" and stopped producing power. He then performed a forced landing to the unimproved airstrip. During the landing, the airplane "bounced," departed the side of the cleared area, entered the woods, and sustained substantial damage. When asked about the performance and handling of the airplane, the pilot said it was "perfect." He stated that the reason for the loss of engine power was carburetor ice and that he had not used carburetor heat for the low approach and pass over the airstrip. The weather conditions in the area at the time of the accident were conducive to serious icing at cruise power. Therefore, it is likely that the pilot's failure to use carburetor heat resulted in an accumulation of ice within the carburetor that led to a total loss of engine power.
On December 24, 2017, about 1500 eastern standard time, a Cessna 172N, N91SP, was substantially damaged during a forced landing in Union Mills, North Carolina. The commercial pilot, who was also the owner of the airplane, sustained minor injuries. Visual meteorological conditions prevailed, and no flight plan was filed for the personal flight conducted under the provisions of Title 14 Code of Federal Regulations Part 91.According to the pilot, the purpose of the flight was to perform approaches to the private airstrip that he was constructing on his property. He said the performance and handling of the airplane was "perfect" throughout the flight, and that he performed multiple low approaches successfully, with no anomalies noted. The pilot said the airplane was travelling slowly over his strip, about treetop height, with full flaps deployed. When he added full power to initiate a climb, the engine "sputtered" and stopped producing power. He performed a forced landing to the unimproved strip, "bounced" and departed the side of the cleared area where the airplane entered the woods and was substantially damaged. When asked about the performance and handling of the airplane, the pilot said it was "perfect" and volunteered that the reason for the loss of engine power was carburetor ice. When asked if he had deployed the carburetor heat for the low approach and pass over his property, he said "No." The pilot held a commercial pilot certificate with ratings for airplane single engine land, and instrument airplane. His most recent Federal Aviation Administration (FAA) second-class medical certificate was issued March 15, 2016. He reported 6,700 total hours of flight experience of which 3,400 were in the accident airplane make and model. According to FAA records, the airplane was manufactured in 1978. Its most recent annual inspection was completed November 12, 2017, at 9,034.9 total aircraft hours. At 1505, the weather reported at Rutherford County Airport (FQD), 7 miles east of the site, included an overcast ceiling at 2,200 ft, 10 miles visibility, and calm winds. The temperature was 10° C, the dew point was 5° C, and the altimeter setting was 29.97 inches of mercury. According to an FAA carburetor icing probability chart, the atmospheric conditions at the time of the accident were conducive to "serious icing" at cruise power.
The pilot's failure to use carburetor heat in weather conditions conducive to serious carburetor icing, which resulted in a total loss of engine power and a subsequent forced landing.
