Technical failure

En route, both engines failed due to fuel exhaustion. The crew completed an emergency landing in a prairie near Lineynoye. The aircraft was damaged beyond repair and there were no casualties.

After takeoff from Krasnoyarsk-Cheremshanka Airport, while climbing to an altitude of 2,040 meters at a speed of 480 km/h, the right engine (engine n°3) suffered an uncontained failure and caught fire. The crew declared an emergency and was cleared to return for an emergency landing. On final approach, the aircraft banked right then nosed down and crashed at a speed of 425 km/h 3,200 meters short of runway threshold and disintegrated on impact, some 11 seconds prior to landing. A passenger was seriously injured while 110 other occupants were 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.

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.

Shortly after climbing and leveling at 6,000 feet, the right engine bmep gage indicated a rapid power loss and the right engine rpm 'increased out of control' to about 3,100 rpm. The aircrew retarded the right throttle and reduced the right engine to 2,100 rpm by using the prop increase/decrease toggle switch. The aircrew were unable to feather the right propeller or maintain altitude, so they diverted to the nearest airport (Walker County). While turning downwind for runway 09, the right engine fire indicator activated and the copilot confirmed a fire. Both fire bottles were discharged and the right propeller stopped rotating. Injection water for the left engine was exhausted and the left engine began backfiring. The captain then maneuvered and landed on runway 27. After touchdown, the right main tires failed, the aircraft veered off the right side of the runway and hit a ditch and the gear collapsed. An exam revealed the #6 cylinder link rod and/or piston in the right engine had failed, resulting in further damage to the engine and #6 cylinder. Subsequently, fire and heat caused the right engine to seize and also damaged the right main tires which failed at touchdown. All 39 occupants were evacuated, among them two passengers were seriously injured.

At 18:12, flight 1039 was cleared for takeoff from runway 31. At 18:13, while over the departure end of the runway and climbing through 600 feet, the crew acknowledged a frequency change. Thirty seconds later, the airplane was seen in a steep a descent near the extended centerline of the runway. The Bandeirante struck the ground 7,800 feet beyond the departure end of runway 31 and 85 feet to the right of the extended runway centerline in an inverted nose down attitude, after which it caught fire and burned. Before ground impact, the horizontal stabilizer, including bulkhead No. 36, had separated from the fuselage. Both elevators and elevator tips, the tail cone assembly, and the aft portion of the ventral fin also had separated in flight. All 13 occupants were killed.

At a height of about 200 feet after take-off the right engine lost power. The pilot feathered the propeller and commenced a gentle left turn in order to return to the strip. He later advised that the aircraft began to sink towards some large trees and he was forced to increase the angle of bank in an effort to avoid them. Shortly afterwards the aircraft struck the ground heavily in an adjacent paddock about 1 kilometre from the strip.

The aircraft was flying from Dublin to Paris (Le Bourget) at a height of 25,000 feet. In the area of Petersfield, Hampshire, the aircraft began a gentle turn to the left from a south easterly heading. After the radar controller queried the departure from the expected heading the commander reported that the autopilot had 'dropped out', and the south easterly heading was resumed. Approximately 7 minutes later, the radar recording shows that the aircraft again began to turn left and started to lose height. After the aircraft had reached a northerly heading it began to lose height rapidly following which secondary radar returns were lost and the primary returns became fragmented before they also disappeared. The aircraft suffered an in-flight disintegration at approximately 19,000 feet and all 9 occupants were killed. A positive cause of the accident was not determined but there was evidence that a part of the aircraft's electrical supply had been lost. This would have caused the autopilot to disengage and also have resulted in the failure of the commander's flight director indicator. It was concluded that, following the disengagement of the autopilot, the aircraft probably entered a steep spiral dive and that the disintegration of the aircraft occurred as recovery was attempted.

While on a cargo flight, the crew got lost after he encountered a sandstorm. When both engines failed due to fuel exhaustion, the crew was forced to make an emergency landing. There were no casualties while the aircraft was damaged beyond repair.
