During arrival to the Kansas City Downtown Airport, the flight was vectored for a VOR runway 03 approach, then was cleared for the approach and to circle and land on runway 36. On final approach, the aircraft was high and was not in a position to land, so the flight was cleared to circle left for another approach to land. The aircrew acknowledged and began circling left which took them in the vicinity of the Fairfax Airport. A short time later, the ATC controller cautioned that the flight might be lining up for the Fairfax Airport. Subsequently, the crew initiated a missed approach and were instructed to turn to 360° and climb to 3,000 feet. The aircraft began a steep climb to 3,100 feet, stalled and entered a steep descent. Before the descent was arrested, the aircraft impacted in a public water treatment plant. CVR recordings indicated that the 1st officer was flying the aircraft during the en route descent, VOR approach and circling approach, then the captain took control during the missed approach. An exam of the wreckage revealed no evidence of an airframe or powerplant problem. Also, there was no evidence that the cargo had shifted. All three crew members were killed.

After being delayed at least 2 days at Youngstown, OH, due to maintenance problems the pilot departed at approximately 1725 hours with the knowledge that the weather at his destination was ift to lifr. In addition, the pilot was scheduled for a vacation and had expressed hopes of departing on it that evening. The aircraft was seen circling West Point Municipal Airport in and out of low clouds, fog, and/or smoke from a nearby mill. Immediately before the aircraft collided with trees 6.5 miles west of the airport, a witness saw red lights, one on the rear and one close to the front of the aircraft, which was estimated to be flying at approximately tree top level. The pilot, sole on board, was killed.

The aircraft collided with trees during the initial takeoff climb from runway 27 at Oakland-Troy Airport, Troy, MI, while on a corporate flight. Investigation revealed that approximately 3 to 5 inches of snow had fallen at the airport during the day and the snow had not been removed from the runway that evening. A witness reported there was 5 inches of snow on the runway and it was snowing at the time of the accident. The pilot reported that 'shortly after takeoff the aircraft yawed, then veered right. Upon correcting this condition left wing struck the ground.' When the right engine was tested a small leak was discovered at the air intake manifold. The left engine was severely damaged by fire and could not be tested. All four occupants escaped uninjured.

The aircraft crashed approximately 1.5 miles south of the departure end of runway 17 during an attempted runway 17 NDB approach. The aircraft was cleared for the approach at 2012 cst and the pilot canceled IFR reporting the airport in sight at 2014. A witness located approximately 1 mile south of the airport reported seeing the aircraft lights through the clouds, mist and fog as it was traveling south-southeast. The aircraft impacted the ground on a heading of 035° in a 10° to 15° left bank. Radar data indicates the aircraft was approximately 8 miles from the airport when IFR was canceled. Witnesses stated visibility in the area was about 1/8 of a mile during the time of the accident. The pilot, sole on board, was killed.

Prior to takeoff the pilot was informed of wind shear as centerfield winds as 270° at 25 knots gust to 46 knots and northwest boundary winds as 280° at 13 knots. During takeoff the pilot reported an opened door and requested to return to land. The aircraft turned left and descended to the ground. Examination of the aircraft did not disclose evidence of malfunction. Examination of the aircraft doors revealed the right side cargo door securing mechanisms were relatively undamaged. Flight test conducted to evaluate the effects of a opened door disclosed in part the following. The door will open and remain open during rotation; results in noise and vibration; no abnormal flight characteristics; no significant change in multi-engine climb performance. Pilot landing in jet aircraft prior to accident reported moderate turbulence with a plus or minus 10 to 15 knots change in airspeed from 2,000 feet msl to the surface. The pilot, sole on board, was killed.

Pilot was cleared for VOR/DME approach to Rogers airport by Fayetteville approach control; Fayetteville altimeter setting of 29.85 (confirmed by recorded transcript) furnished. Pilot did not read back. During approach, aircraft impacted trees 25 feet agl at approximately 1,320 feet msl, 3 miles short of airport. Investigation showed pilot's altimeter set at 30.14 (altimeter would read 290 feet higher than aircraft actual altitude). Pilots's recall was that the 30.14 setting was furnished by approach control. Pilot further stated last recalled altitude reading was 1,750 feet. Approach plate shows 1,700 feet mda with Rogers altimeter setting; increase mda by 100 feet if using Fayetteville setting. The pilot was seriously injured and the passenger was killed.

No evidence of preimpact mechanical failure or malfunction was noted during wreckage examination. The FAA operations inspector who was on board at the time of the accident stated there were no aircraft problems involved. The pic, who was in the process of taking her type rating checkride in the aircraft, failed to maintain directional control during a simulated engine failure after reaching V1 speed during the takeoff run. The total flight experience for the pic was 2,454 hours, most of which was acquired in multi-engine aircraft, with 387 hours being in the make and model aircraft involved in the accident. All listed experience in this make and model was obtained as second-in-command. All three occupants were killed.

Aircraft was performing test flight maneuvers when problems with the modified fuel system occurred. Ice blocking a fuel vent line caused a partial collapse of the main (engine feed) fuel cell which produced an erroneous fuel quantity reading. In addition, the main tank overflow shut off valve was leaking, so tank overflow occurred. The fuel overflow caution light illuminated and auxiliary tank fuel pump feed to main automatically shut down. Due to miscalibration, this system overrode pilot attempts to restart aux fuel pumps. Pilot remained in test area troubleshooting rather than immediate return to base, finally noted main tank gage continuing to read 'full.' En route to Boeing Field, fuel starvation occurred. Pilot opted to attempt forced landing in small athletic field in residential area rather than ditch in puget sound. The aircraft touched down in intended landing area, then bounced across an adjacent street. The arresting action of telephone wires on the vertical fin brought the aircraft to rest in a residential backyard. All three occupants were injured, one seriously.

About 2 hours after departure, at 13,000 feet, the right engine fuel flow went to zero. The engine continued to operate indicating 24 inches of manifold pressure. All other instruments were normal but what looked like a brown stain developed on top of the right wing along the spar cap near the tip tank. Artcc was advised that a precautionary landing would be made at Raton and a rapid descent was begun. On final the right engine nacelle and wing locker turned brown. As the aircraft landed flames appeared on the right side of the fuselage and smoke entered the cabin. Both engines were secured and brakes applied. The brakes were inoperative therefore, the pilot steered the aircraft off the runway into a snowbank collapsing the nose gear. Within 15 mins most of the wreckage was consumed by the fire. Ignition source and fire origination point were not determined. All three occupants escaped uninjured.

The aircraft took off from an airport whose runways had been closed for snow removal. A notam had been filed with the Fresno FSS by the Mammoth Lakes Airport Manager at 0900 hours for taxi and runway snow removal. The pilot was aware of the notam because the manager and a lineman both said they advised him of it. Several witnesses saw the pilot enter the aircraft after declining engine pre-heat or aircraft de-icing. When advised by the lineman that the 2 qts of oil that the pilot requested did not 'register on the dipstick.' The pilot ordered another qt to be 'thrown' in and 'hurry up.' No preflight or warm up or before takeoff check was noted by observers. Turning immediately onto the runway and rolling for takeoff the pilot passed a snow plow. The aircraft used 7,000 feet (all of the runway) and left the ground in a nose high attitude. The airport elevation is 7,128 feet msl. The aircraft first struck a dirt mound 3/4 of a mile after takeoff. After maintaining further flight for approximately 280 feet which crossed a small ravine the aircraft collided with the far side of the ravine and started to break apart, stopping 144 feet further east. The pilot, sole on board, was killed.
