Takeoff (climb)

A witness reported the airplane did not climb above 200 feet and reported seeing the airplane 'wobbling up and down' as it attempted to climb. He reported the airplane went into a sharp left bank and nose dived down. The airplane burned upon impact. The wreckage was located in a wooded area about 3/4 mile from the approach end of runway 30. Numerous open farm fields were located near the airplane's flight path. The winds were reported at 240 degrees at 22 knots gusting to 29 knots. The wreckage path was on a 040 heading and covered about 190 feet from initial tree impact to the location of the main wreckage. The engine inspection did not reveal any anomalies to either engine. The flight was the first maintenance check flight after the airplane had not been flown for 14 months. During maintenance the pilot had put about 100 gallons of water in the left main and left auxiliary fuel tanks to locate a fuel leak. A plug was installed in the left auxiliary fuel drain valve and the fuel tank could not be checked during preflight for fuel contamination without removing the plug.

The airplane had just taken off and was at approximately 300 agl when the right engine 'had a sudden and catastrophic failure.' The right propeller stopped spinning with the blades in the low-pitch position. The pilot initiated a right turn back toward the airport, but the airplane would not maintain altitude. The pilot rolled out of the turn, but the descent continued until the airplane struck the trees. Examination of the airplane's right engine revealed that the crankshaft was broken at the number 3 short cheek, just forward of the number two cylinder piston rod. The number two crankshaft bearing was broken and melted. The oil feed line to the number two bearing was blocked by a piece of the broken bearing. The Single Engine Climb Data table in the Cessna 414 Pilot's Operating Handbook indicates that an airplane weighing 5,680 pounds, with gear and flaps retracted and the inoperative propeller in feather, operating at a density altitude of 5,055 feet, will have a best climb indicated airspeed of 115 knots. The rate of climb will be 308 feet per minute.

Few minutes after takeoff from Erdenet Airport, while climbing in low visibility due to poor weather conditions, the twin engine aircraft struck the slope of a mountain (2,800 metres high) located few km west of the airport. The aircraft disintegrated on impact and all 28 occupants were killed, 16 adults and 12 children.

During the takeoff roll at Kendari-Wolter Monginsidi Airport, at Vr speed, the cargo door warning light illuminated on the cockpit panel. The captain decided to abort and initiated an emergency braking procedure. Unable to stop within the remaining distance, the aircraft overran, lost its undercarriage and came to rest 200 metres further. All 64 occupants escaped uninjured and the aircraft was damaged beyond repair.

The aircraft was returning to Nouakchott with 35 passengers and seven crew members who accompanied the President of the Republic of Mauritania on an official visit of the Hodh Ech Chargui Region. All passengers were members of the Mauritanian Army fanfare. Shortly after a night takeoff, while in initial climb, the aircraft stalled and crashed in a huge explosion near the runway end. Three passengers were seriously injured while 39 other occupants were killed. The aircraft was totally destroyed by impact forces and a post crash fire.

During the takeoff roll at Lanseria Airport, the crew encountered technical problems and elected to abort. Unable to stop within the remaining distance, the aircraft overran and came to rest, bursting into flames. There were no casualties.

The flight from Bogotá to Quito was completed by TAME on a wet-lease contract for Air France, second leg from the AF422 flight from Paris to Quito via Bogotá operated by an Airbus A340. After takeoff from runway 13 at Bogotá-El Dorado Airport, the crew was cleared for a Girardot 1 departure that consist of continuing on runway heading for 2 miles after takeoff, followed by a 90° right turn over the Romeo beacon. For unknown reasons, the crew continued straight forward until the aircraft impacted the Mt El Cable located ahead of the airport. The aircraft disintegrated on impact and all 53 occupants were killed, among them 25 European Nationals, seven Italians, six French, three Danish, three Spanish, two Germans, two Austrians, one British and one Swiss. The wreckage was found 50 metres below the summit. At the time of the accident, weather conditions were poor with rain, clouds at 2,300 feet and CB's.

Shortly after takeoff from Novaya Derevnya, while climbing to a height of about 10 metres, the aircraft rolled to the left to an angle of 35°, lost height and crashed into trees located 145 metres further. Both pilots were injured and the aircraft was damaged beyond repair.

The twin-engine Aerostar departed on Runway 1. While on initial climb, after take-off, witnesses observed the airplane roll to the left until it became inverted, after which the nose dropped and the airplane impacted the ground in a near vertical nose down attitude. The fuselage was consumed with a post crash fire. On-site examination revealed the wing flaps and landing gear were retracted. No evidence of a mechanical failure or malfunction was found relating to the airplane, engines, or propellers. The investigation revealed that both propellers were rotating and absorbing power at the time of impact. The winds were reported from 360 degrees at 17 knots, with gusts to 25 knots.

The pilot lost control of the airplane following the loss of engine power from the right engine during takeoff. The pilot stated that the engine power loss was not sudden, but rather a slow continued reduction of power. The pilot further stated that the loss of power occurred after he placed the landing gear selector in the retract position. He added that his airspeed at the time of the power loss was between Vmc (86 mph) and Vy (120 mph). The airplane started to roll towards the right (dead) engine as the pilot reduced the power on the left engine. The outboard portion of the right wing impacted the ground short of a taxiway. Examination of the wreckage revealed that the right engine propeller was in the feather position and the left engine was torn from the airframe. The reason for the loss of engine power was not determined.
