Introduction
A private pilot with 1,300 hours of flight experience experienced a loss of engine power during the initial takeoff climb. The event occurred on a turf runway with a field elevation of 3,615 feet.
Sequence of Events
According to the pilot, while climbing at an estimated altitude of 75 to 80 feet above ground level, the engine rpm decayed to 1,950. The airplane's rate of climb subsequently decreased to zero. The pilot responded by lowering the nose and extending the flaps. With no usable runway remaining, the pilot turned the airplane to the left and elected to conduct an emergency landing to a field. While maneuvering to avoid a fence, the airplane stalled, impacted the terrain, and came to rest on its right side. The pilot, three passengers, and two small dogs were able to egress the airplane unassisted. A few minutes later, the airplane became engulfed in flames.
Weather and Density Altitude
Approximately 13 minutes after the mishap, an automated weather station located 12 miles northeast of the accident site reported wind from 040 degrees at 13 knots, temperature 57°F, and dew point 55°F. According to a carburetor icing probability chart, at the reported temperature and dew point, the airplane was operating within the range described as "serious icing at cruise power." The airport's calculated density altitude was 4,347 feet, with a field elevation of 3,615 feet. The estimated weight of the airplane at departure was its maximum takeoff weight of 2,300 pounds.
Post-Accident Examination
An examination of the engine revealed no mechanical anomalies. Runway 35 measured 3,800 feet long by 60 feet wide and was composed of turf. The report did not specify a probable cause for the power loss.
