Accident Overview
A training airplane experienced an engine failure shortly after takeoff, resulting in substantial damage when it struck trees and terrain. The incident occurred at about 150 feet above ground level. The flight instructor (CFI) and student pilot were on board. The aircraft was maneuvering to avoid houses and property before impacting a tree.
Pilot Statements
The CFI reported that during a normal takeoff, at approximately 150 feet above ground level, the engine began developing less than full power. Unable to maintain altitude, he maneuvered to avoid houses and property, with the last choice being to fly into a tree. The student pilot stated that at about 150 feet above ground level, the aircraft stopped climbing and the CFI took over the controls. The CFI checked the throttle to ensure it was fully applied. At that point, the aircraft was slowing down and losing airspeed and altitude, with RPM dropping to about 2300. The student noted that carburetor heat was not used during the flight.
Examination Findings
An on-scene examination of the wreckage revealed no pre-impact anomalies. The carburetor heat lever was found in the off position. The local temperature and dew point at the time of the accident were plotted on a Transport Canada carburetor-icing chart. Their intersection fell in the moderate icing-cruise power or serious icing-descent power area, indicating potential for carburetor icing under the prevailing conditions.
