NTSB analysis

Radar data indicated that the airplane's flight track diverted to the nearest airport shortly after the pilot declared the emergency. Radar and radio communications were lost about 7 minutes later, when the airplane was about 4 nm west of Frankfort, Michigan, at an altitude of 700 ft and an airspeed of 77 mph.

Ten days later, using a remotely operated underwater vehicle to search Lake Michigan in the area of the airplane's last radar contact, the Michigan State Police located the airplane at a water depth of 540 ft. The wreckage was not recovered; therefore, the engine could not be examined, and the reason for the loss of engine power could not be determined.
