NTSB Identification: MIA97LA033. The docket is stored in the (offline) NTSB Imaging System.

Accident occurred Monday, December 02, 1996 at HOMERVILLE, GA

Aircraft: Cessna 150H, registration: N6532S

Injuries: 2 Uninjured



Event: 20001208X07209 Status: Final Report Approved On Friday, May 23, 1997



NTSB Preliminary Narrative (6120.19A)



On December 2, 1996, about 2025 eastern standard time, a Cessna 150H, N6532S, registered to a private owner, operating as a Title 14 CFR

Part 91, personal flight, crashed during a forced landing near Homerville, Georgia. Visual meteorological conditions prevailed and a VFR flight

plan was filed. The airplane was substantially damage. The airline transport pilot, and one passenger were not injured.



The airplane's engine lost complete power, and the pilot requested radar vectors to the nearest airport. The pilot was vectored to Homerville,

and while on short final, the airplane struck trees, turned 180 opposite the direction of travel, and impacted the ground.



The pilot stated that just after establishing radar contact with ATC, the airplane "experienced [a] power failure." The engine then surged

momentarily, for about 30 seconds then stopped. The pilot did not try to restart the engine again, and performed a forced landing, but was not

able to reach the airport because of the head winds.



According to the FAA inspector's statement, the airplane had begun a descent from 6,000 feet, shortly before the engine failed. The

carburetor heat control was found in the "cold" position, and the fuel selector was "on." Both fuel tanks, and the gascolator sump drain,

"contained fuel." The airplane's engine was examined, started and ran without any discrepancies noted. The FAA inspector wrote in his

statement that based on the engine run the cause of the loss of engine power "could not be determined." He further stated "the possibility of

carburetor icing does exist."



NTSB Final Narrative (6120.4)



The airplane's engine lost complete power, and the pilot requested radar vectors to the nearest airport. While on short final, the airplane struck

trees, turned 180 opposite the direction of travel, and impacted the ground. The pilot stated that just after establishing radar contact with ATC,

the airplane 'experienced [a] power failure.' The engine then surged momentarily for about 30 seconds, then stopped. The pilot did not try to

restart the engine again. He performed a forced landing, but was not able to reach the airport due to head winds. The airplane had begun a

descent from 6,000 feet, shortly before the engine failed. The carburetor heat control was found in the 'cold' position, and the fuel selector was

'on.' Fuel was found in both fuel tanks. The airplane's engine was examined, started, and ran without any discrepancies noted. About 31 miles

west-southwest at Valdosta, Ga, the temperature and dew point at 1955 EST were 46 and 41 degrees, respectively. According to icing

probability charts, conditions at Valdosta were conducive for carburetor ice.



NTSB Probable Cause Narrative



carburetor ice, due to the pilot's improper use of carburetor heat, which resulted in a forced landing and impact with trees.
