Aircraft Accident/Incident Report

Manville, New Jersey 08835
Saturday, July 24, 1999 11:40 EDT

NTSB Narrative Summary Released at Completion of Accident

After takeoff, the CFI noticed that the airspeed 'began to decay;' however, the engine was still producing power, as he performed a forced landing to a field. After exiting the airplane, the CFI explained to the passenger that they had 'not produced enough power to gain altitude,' because they may have been 'too big' and it was 'too hot' of a day for the airplane to perform. Examination of the engine revealed no pre-impact malfunction, and the carburetor heat control was observed extended in the mid range position, which was consistent to the lever located at the carburetor heat box. According to the airplane manual, the takeoff checklist procedure includes assuring the carburetor heat is in the cold position. The basic empty weight of the airplane was 1,109 pounds and the maximum takeoff weight was 1,600 pounds. The passenger and CFI weights were reported as 250 and 200 pounds, respectively. The pilot determined there was 14 gallons of fuel onboard the airplane before takeoff. According to the temperature and elevation reported at the airport, the density altitude was calculated as 1,747 feet.

NTSB Probable Cause Narrative

The pilot's failure to follow the checklist and improper use of the carburetor heat. A factor in the accident was determined to be the density altitude.
