The parents of the pilot/owner stated that he arrived late in the afternoon prior to the accident. They stayed up with their son until approximately 0100 the morning of the accident. They stated that their son was a doctor and kept a busy schedule. The son told the parents that he had to fly back in order to have new fuel cells installed in the airplane and to work at his clinic. The pilot was airborne by 0700. The weather at his destination had low ceilings and fog restricting the visibility. The pilot was cleared by ATC to fly the localizer approach to the runway. The pilot called his position at the outer marker on the unicom frequency and no further transmissions were heard. Witnesses on the airport heard and saw the bottom of the airplane and stated that the airplane's engines sounded normal as it went overhead. Radar data showed that the airplane's altitude fluctuated and ground speed decreased significantly during the missed approach flight path. The airplane impacted the ground in approximately 40- degree nose-low, right wing down attitude. The toxicology report revealed 0.005 ug/ml Tetrahydrocannabinol (Marihuana) in the blood, and 0.013 ug/ml and 0.017 ug/ml Tetrahydrocannabinol Carboxylic Acid (Marihuana) in the blood and kidney fluid respectively.

The airplane was on takeoff climb, about 400 feet above the ground, when the engine partially and then totally lost power. The pilot did a forced landing in a bean field. The flight occurred following maintenance to check a low manifold pressure condition. According to the pilot, a 'full' engine runup was done before takeoff. He stated: 'the takeoff was smooth, we rotated at an airspeed of slightly more than 80 knots. The climb for the first 350 (feet of altitude), airspeed was routine... I felt a power loss and noticed the manifold pressure dropping. At this point I felt I had enough power to return to the airport... as the turn was being completed, power went out completely.' The post-accident examination of the airplane did not disclose evidence of mechanical malfunction.

Just prior to the accident the airplane was seen on final approach flying in an erratic manner at a low altitude. Two witnesses riding in a car wrote they saw the airplane, 'going up and down toward the ground. We could hear a faint clicking noise, and the propellers were going around slowly.' The witnesses saw the airplane take 'a short nosedive and crashed.' They wrote that the airplane was not traveling 'very fast and it was pretty level to the ground.' The witnesses could not hear the engines because they were in a car. According to fuel records, the pilot of N1576T put 112 gallons of fuel on board the airplane on march 17, 1994, and the flight started at 1030 on march 19, 1994. The accident occurred at 1355, for a total flight time of 3 hours and 25 minutes. Using fuel consumption data for this aircraft it was estimated that fuel exhaustion would occur after 3 hours and 4 minutes of flight. The pilot, sole on board, was killed.

The airplane stalled and crashed 1.2 nautical miles east of runway 28L during an ILS approach. The captain initiated the approach at high speed & crossed the FAF at a high speed without first having the airplane properly configured for a stabilized approach. The airspeed was not monitored nor maintained by the flightcrew. The airline had no specified callouts for airspeed deviations during instrument approaches. The captain failed to apply full power & configure the airplane in a timely manner. Both pilots had low flight time and experience in in the airplane and in any EFIS-equipped airplane. Additionally, the captain had low time and experience as a captain. Inadequate consideration was given to the possible consequences of pairing a newly upgraded captain, on a new airplane, with a first officer who had no airline experience in air carrier operations, nor do current FAA regulations address this issue.

En route at FL240, the plane entered a left spiraling descent and subsequently experienced an inflight break-up at 7,000 feet with separation of outboard wings, tail sections and internal vinyl from the nose baggage door. There was no distress call. Witnesses heard the engines and an explosive sound, then they saw the plane in a spin, trailed by falling debris. Debris was strewn over a distance of about 3.5 miles. Light weight pieces including vinyl from the baggage door, wing skin, and tail skin pieces were among the 1st debris on the wreckage path. Tail sections were found about 2.5 miles from the main wreckage with evidence of overload failure; pieces of the wings were found with evidence of downward/overload separation. No preexisting airframe failure was found that would have led to loss of control, inflight breakup, loss of pressurization or hypoxia. The plane was inactive for about 2 years before being purchased 2 months before accident. Last annual inspection was on 6/8/92. Icing was forecast from 9,000 feet to 17,000 feet msl; turbulence was forecast below 8,000 feet msl. Both occupants were killed.

After rotation, during the initial climb, the nose of the airplane pitched up to approximately 60° above the horizon. The airplane continued to climb until about 250 feet above the ground, then rolled right, pitched down and descended. The airplane impacted the ground, approximately 45° nose down, 650 feet to the right of the runway. Post accident investigation of the wreckage revealed the elevator jammed in the full up deflection. The upper end of the elevator control rod was found not connected to the elevator, but was found laying aft, wedged between the tail cone and the elevator faring, holding the elevator in the full up position. The control rod connecting bolt was found laying in the bottom of the tail cone undamaged. The washer, nut and cotter pin related to the control rod connecting bolt were not found. The elevator had been removed, recovered and then installed by company maintenance personnel 166 flight hours prior to the accident. The pilot, sole on board, was killed.

The crew departed Wilmington-Air park (Clinton County Airport) on a local training flight. On final approach to runway 22, the crew forgot to lower the undercarriage and the aircraft landed on its belly. It slid for few dozen yards and came to rest on the main runway. All three occupants escaped uninjured while the aircraft was damaged beyond repair.

ATI Flight 805 departed from Seattle at 23:20 for a flight to Toledo. The 1st officer was flying the ILS approach to runway 07. For undetermined reasons, he failed to properly capture the ILS localizer and/or glide slope during the approach. At 03:13 the captain decided to carry out a go-around. The aircraft was vectored onto a base leg and given a heading of 100° to intercept the final approach course again. With a 35 knots crosswind (at 180°) on the approach the 1st officer had trouble capturing the localizer/glide slope. At 03:24, as the 1st officer was attempting to stabilize the approach, 3 GPWS glideslope warnings and sink rate warnings sounded. The captain took over control at 03:24:17 and performed another missed approach manoeuvre. He became spatially disoriented and inadvertently allowed an unusual attitude to develop with bank angles up to 80° and pitch angles up to 25°. When in a nose-low and left bank angle attitude, control of the airplane was transferred back to the 1st officer who began levelling the wings and raising the nose of the airplane. Impact with the ground occurred before the unusual attitude recovery was completed. All four occupants were killed.

The pilot had the waste gates on the turbocharges adjusted and wanted to test fly the airplane after the work was completed. The airplane departed and had reached an altitude of about 1,000 feet when witnesses heard an engine sputter. The airplane was seen making a left turn and enter a nose low, left spin before impacting the terrain. A tear down of the left engine revealed that the exhaust valves in cylinders #3 and #5 were burnt through at the valve head. The #5 exhaust valve had a deep preexisting deep mark on the valve stem. The failures of both valves were sufficient enough to cause a power failure in the left engine. The pilot, sole on board, was killed.

The pilot made routine radio communications in preparation for takeoff. The airplane departed from runway 25 in daylight instrument meteorological conditions (IMC) with light snow and fog. Shortly after takeoff, the airplane's radar target disappeared from the controller's scope. The airplane crashed on wooded terrain about two miles south-southwest of the departure end of runway 25. Impact occurred in an steep, nose down, left wing low attitude. The airplane was destroyed by ground impact forces and a post-impact fire. No physical incapacitation of the pilot-in-command was determined. No contributory mechanical malfunctions of the airplane were discovered. All three occupants were killed.
