Accident Details
A pilot obtained a preflight briefing and indicated intentions to obtain an IFR clearance after becoming airborne. However, the pilot took off without activating a flight plan. Witnesses observed the airplane flying north, away from its intended destination, at an altitude of approximately 200 to 300 feet above the ground beneath a low overcast sky. One witness reported that the airplane was flying very slowly, such that he was almost able to keep pace with it in his vehicle.
Collision Sequence
Witnesses saw the airplane roll rapidly to the right and descend toward the ground. The airplane collided with the ground in an approximate 50-degree pitch-down attitude.
Investigation Findings
An on-scene examination did not reveal any airframe or control anomaly that would have resulted in the accident. The engines and propellers were disassembled for inspection. Examination of the engines revealed they were capable of producing power. Examination of the propellers revealed both were operating at low pitch settings.
Weather Conditions
About 25 miles north-northwest at Battle Creek, Michigan, the 1145 EDT weather was: 500 feet overcast, visibility 2 miles with fog, wind from 050 degrees at 10 knots.
