Aircraft Accident/Incident Report
Boyd, Texas 76023
Friday, January 9, 1998 12:45 CST
NTSB Narrative Summary Released at Completion of Accident
The instrument student was practicing standard rate (500 fpm) descents and climbs, and the flight had descended with the power at 2,000 RPM from 3,000 feet MSL to 1,500 feet MSL. When the student applied full throttle for the climb, the engine power did not increase. The flight instructor took the flight controls and applied carburetor heat; however, the power decreased through 1,500 RPM to 1,200 RPM. The field selected for the forced landing was rough and the airplane struck the ground and again became airborne. The flight instructor, observing a powerline and fence ahead of the airplane, flew the airplane under the powerline and over the fence. Subsequently, the airplane 'stalled' and impacted the ground. The NWS reported the temperature was 46.4 degrees Fahrenheit with a dew point of 39.2 degrees Fahrenheit and a relative humidity of 61 per cent. The icing probability curves showed the conditions to be favorable for serious carburetor icing.
NTSB Probable Cause Narrative
loss of engine power resulting from the pilot's delayed use of carburetor heat during serious carburetor icing conditions. Factors were: the lack of suitable terrain for the forced landing and an evasive maneuver which led to an inadvertent stall.
