Narrative Report
On January 23, 2002 at 07:35 AM, Sturgis - Ann Arbor experienced a crash involving Cessna 402, operated by Riley Aviation, with the event recorded near Bronson Michigan.
The flight was categorized as positioning and the reported phase was flight at a plain, valley crash site.
1 people were known to be on board, 1 fatalities were recorded, 0 survivors were identified or estimated. This corresponds to an estimated fatality rate of 100.0%.
Crew on board: 1, crew fatalities: 1, passengers on board: 0, passenger fatalities: 0, other fatalities: 0.
The listed crash cause is human factor. The airplane was destroyed when it impacted the ground while maneuvering at a low altitude following a loss of control in instrument meteorological conditions. The airplane was on a flight in instrument meteorological conditions when radar and voice contact were lost. Prior to the loss of communication, controllers advised the pilot to check altitude. At this point, the radar data shows that the airplane was about 400 feet below the assigned altitude. Subsequently, the pilot said, "roger sir my auto pilot i just cut off uh correcting immediately." This was the last received transmission from the pilot. The radar data shows that the airplane then began a descending right turn at an average rate of descent of 1,276 feet per minute. This descent was followed by a climbing left turn with an average rate of climb of 5,423 feet per minute. The radar data shows that the radius of the left turn continued to decrease until radar contact was lost about 500 feet above the last assigned altitude. A witness who saw the airplane just prior to impact described the airplane maneuvering beneath the clouds prior to pulling up sharply and then pitching down and impacting the ground. There was a utility wire and associated poles running across the airplane's flight path in the field where the wreckage was located. The airplane exploded and burned upon impact. No anomalies were found with the airplane or associated systems. The autopilot section of the Pilot's Operating Handbook states, "Sustained elevator overpower will result in the autopilot trimming against the overpower force." The result is that if up elevator pressure is applied with the autopilot engaged, the autopilot will trim the airplane nose down.
Aircraft reference details include registration N371JD, MSN 402B-1322, year of manufacture 1978.
Geospatial coordinates for this crash are approximately 41.8723°, -85.1947°.
