From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

(.4) The aircraft experienced an engine failure after departure. The certified flight instructor (CFI) executed a forced landing on a road where the aircraft wing contacted a semi-truck. A postaccident examination revealed no preexisting anomalies with respect to the aircraft or aircraft systems. The CFI reported no mechanical malfunction. A weather report stated a temperature of 32 degrees f., and a dewpoint of 28 degrees f. according to the carburetor icing chart by transport Canada, the temperature and dewpoint at the time of the accident fall within the range of serious icing potential. FAA ac 20-113 states, 'when the relative humidity is above 50 percent and the temperature is below 70 degrees f., apply carburetor heat briefly immediately before takeoff, particularly with float type carburetors, to remove any ice which may have been accumulated during taxi and runup.' (-23) first flight of the day, temp and dew point close. During climb-out, about 700 feet AGL, engine lost power. Flight instructor assumed control and executed a 180 degree turn to return to airport. Due to terrain (hills an d wooded area) pilot unable to reach airport. Completed 90 degree turn to left and completed forced landing on highway just south of airport. Aircraft sustained substantial damage due to hard landing. No injuries to pilot or passenger. Inspection of the engine found no mechanical problems. Engine had a satisfactory ground run.
