The airplane was used to transport unspecified organs for transplant to a patient in Michigan. The pilot executed a climbing right turn to a northeast heading. The airplane's initial climb lasted for approximately one minute at which time the airplane levels off for approximately 16 seconds at a pressure altitude of 3,900 feet. The airplane then began another climb at about 1,300 feet per minute. This climb lasted for about 32 seconds at which time the airplane's pressure altitude was 4,400 feet. Radar data then showed the airplane in a descending left turn for the remaining 69 seconds of the data. The average descent rate during this period was 2,260 feet per minute. The airplane impacted the water of Lake Michigan approximately 243 knots indicated airspeed, 42 degrees nose down, and 115 degrees left wing down.
During the climb the crew declared an emergency and their intention to return to Milwaukee. During those communications, one of the flight crewmembers reported that they had experienced a runaway trim.
Probable Cause:PROBABLE CAUSE: "The National Transportation Safety Board determines that the probable cause of this accident was the pilotsí mismanagement of an abnormal flight control situation through improper actions, including failing to control airspeed and to prioritize control of the airplane, and lack of crew coordination. Contributing to the accident were Marlin Airís operational safety deficiencies, including the inadequate checkrides administered by Marlin Airís chief pilot/check airman, and the Federal Aviation Administrationís failure to detect and correct those deficiencies, which placed a pilot who inadequately emphasized safety in the position of company chief pilot and designated check airman and placed an ill-prepared pilot in the first officerís seat."
