Takeoff (climb)

The aircraft departed Chanthaburi Airport for a cloud-seeding mission with four passengers and a pilot on board. Shortly after takeoff, while climbing, the engine failed. The aircraft stalled and crashed, bursting into flames. A passenger was seriously injured while four other occupants were killed.

The aircraft departed Payam Airport on a cargo flight to Sharjah. Shortly after takeoff, while in initial climb, the crew declared an emergency following technical problems with three engines and was cleared for an immediate return. After the captain realized he could not make it, he attempted an emergency landing when the aircraft crash landed in a field located 5 km from the airport. On impact, the aircraft broke into several pieces, bursting into flames. All 12 occupants escaped with minor injuries.

Shortly after takeoff from runway 05 at Cuenca-Mariscal La Mar Airport, while climbing to a height of 300 feet, the engine failed. The airplane lost height, causing the nose wheel to struck the roof of a building. Out of control, the aircraft crashed onto a building occupied by a rubber company. Five passengers were killed while nine other occupants were seriously injured. There were no injuries on the ground. The aircraft was destroyed.

During the takeoff roll, after the pilot disengaged the nose gear steering, the airplane began to turn to the right. The copilot noticed fluctuations with the engine indications, and called for an abort. Power was reduced to idle, and the pilot corrected to the left using left rudder pedal and braking. The airplane turned to the right again, and the pilot corrected to the left. The airplane continued to turn left, and departed the left side of the runway, tail first, and was substantially damaged. The airplane had accrued 18,040.3 total hours of operation. It was powered by two turbofan engines, each equipped with an electronic fuel computer. Examination of the left engine's wiring harness revealed that the outer shielding on the fuel computer harness assembly was loose, deteriorated, and an approximate 3-inch section was missing. Multiple areas of the outer shielding were also chaffed, the ground wire for the shielding was worn through, and the wiring was exposed. Testing of the wiring to the fuel computer connector, revealed an intermittent connection. After disassembly of the connector, it was discovered that the connector pin's wire was broken off at its crimp location. Examination under a microscope of the interior of the pin, revealed broken wire fragments that displayed evidence of corrosion. Simulation of an intermittent electrical connection resulted in N1 spool fluctuations of 2,000 rpm during engine test cell runs. According to the airplane's wiring maintenance manual, a visual inspection of all electrical wiring in the nacelle to check for security, clamping, routing, clearance, and general condition was to be conducted every 300 hours or 12 calendar months. Additionally, all wire harness shield overbraids and shield terminations were required to be inspected for security and general condition every 300 hours or 12 calendar months, and at every 600 hours or 24 calendar months. According to company maintenance records, the wiring had been inspected 6 days prior to the accident.

The aircraft was flying back to Paraná (Argentina) with an intermediate stop at Santa Cruz with 3 military personnel and 3 technicians and board. They came in La Paz to deliver humanitarian aids after important flood in Bolivia. Shortly after takeoff, while in initial climb, the aircraft entered an uncontrolled descent and crashed in an open field located 20 km from La Paz-El Alto Airport. All six occupants were killed.

During the takeoff roll at Cap Haïtien Airport, the captain decided to abandon the takeoff procedure. Unable to stop within the remaining distance, the aircraft overran. The left hand side of the fuselage was punctured by propeller parts coming from the left engine. All occupants escaped uninjured while the aircraft was damaged beyond repair. The exact date of the mishap remains unknown, somewhere in January 2006.

The pilot stated that during takeoff, "after becoming airborne, the airplane quit accelerating and a positive climb rate was not established." He pushed the power lever all the way forward, but did not feel a response from the airplane. Witnesses reported that the airplane became airborne, but failed to gain altitude and struck an antenna array and a fence off the departure end of the runway. The airplane continued across a slough, struck an embankment and came to rest about 900 feet from the departure end of the runway on a golf course located adjacent to the airport. Examination of the airplane revealed no pre-mishap airframe anomalies. Examination of the engine revealed that the compressor and power turbines displayed moderate circular rubbing damage to the blades suggesting engine operation at impact, likely in the low to mid power range. Examination of the airframe and engine revealed no anomalies that would have prevented the engine from producing power prior to impact. The reason for the partial loss of engine power was not determined.

Shortly after takeoff from Zalingei Airport, en route to Al Fashir on behalf of the African Union, the twin engine aircraft crashed in unknown circonstances. Both pilots, Ukrainian and Moldavian citizens, were killed.

On a flight from Baku to Aktau in difficult weather conditions at night when took off with caged gyro horizons, so the crew lost spatial orientation. The aircraft entered a steep right downward spiral and crashed on the shore of the Caspian Sea near Nardaran, some 35 km northeast of Baku, less than five minutes after takeoff. All 5 crew and 18 passengers were killed, among them were 15 Azeris, one Briton, one Australian, one Turkish, one Georgian and 4 Kazakh.

At 1834 Pacific standard time, the Nav Air Charter Inc. Mitsubishi MU-2B-36 aircraft (registration C-FTWO, serial number 672) took off from Runway 15 at the Terrace Airport for a courier flight to Vancouver, British Columbia. The left engine lost power shortly after take-off. The aircraft descended, with a slight left bank, into trees and crashed about 1600 feet east of the departure end of Runway 15 on a heading of 072° magnetic. The aircraft was destroyed by the impact and a post-crash fire, and the two pilots were fatally injured.
