Takeoff (climb)

The airplane had undergone routine maintenance for slow acceleration on the right engine. Maintenance records revealed the fuel controls were changed from the right engine to the left engine. The airplane was released back to the pilot for service, and he departed for his home station. Several witnesses saw the airplane after takeoff at a low altitude, and at a slow speed. The airplane turned left, and the left wing struck the ground. Two witnesses saw the airplane pass by them at a low altitude, and wrote, '...at this point we could see the left (port) engine propeller was turning very slowly. You could actually see the individual blades of the propeller turning.' A complete disassembly of both engines, revealed no discrepancies other than impact, and post impact fire damage. Disassembly of the left propeller indicated that the propeller blades were at or near feather at impact. The pilot had a total of 106 flight hours in Beech A100 aircraft, all in the 90 days prior to the accident, and 56 hours in the 30 days prior to the accident.

Around 1950 eastern daylight saving time (EDT), the Cessna 421C aircraft, registration C-GVPB, operated by les Ailes de Charlevoix inc., took off on a visual flight rules (VFR) charter flight from Charlevoix Airport, Quebec, to Trois-Rivières, Quebec, with one pilot and five passengers on board. Shortly after take-off, witnesses saw greyish smoke emanating from the left engine. The aircraft entered a steep left turn followed by a descent. It then continued in the new direction. Shortly after, the aircraft yawed and entered an uncontrolled roll, nosed down, and crashed. The aircraft caught fire on impact. All six occupants were fatally injured during the impact. The aircraft was destroyed.

After takeoff from Eskişehir Airport, while in initial climb, the crew declared an emergency after the right engine exploded and caught fire. The crew was able to return when the aircraft crash landed and came to rest, bursting into flames. All three crew members escaped uninjured while the aircraft was destroyed by fire.

The aircraft departed Colón-Enrique Adolfo Jiménez Airport in poor weather conditions (low pressure zone). During initial climb, the aircraft suffered an explosion and crashed 10 km from the airport. The crew did not send any distress call. The aircraft disintegrated and all 21 occupants were killed, among them 12 Jewish businessman.

The emergency medical service (EMS/medevac) flight was dispatched to transport a patient in response to a medical emergency. During arrival to the destination, the pilot contacted the airport unicom for advisories and was advised to land on runway 25. Runway 25 had a 2.2 percent uphill grade and was restricted to landings only. After landing, the airplane was refueled and the patient was put on board. The pilot back-taxied on runway 25 and proceeded to take off uphill with the airplane near its maximum gross weight. According to ground witnesses, there was a tailwind, which they estimated was between 4 and 15 knots. The temperature was about 100 degrees, and the density altitude was about 3,200 feet. After the airplane became airborne, the pilot started an immediate left turn to avoid rising terrain. However, the left tip tank contacted the ground, and the airplane cartwheeled. It came to rest about 711 feet from the departure end of the runway. The flaps and landing gear were found fully extended; the published configuration for takeoff data in the flight manual was for 'wing flaps - up.' The airport had no signs to indicate runway use restrictions; however, the restrictions were published in the airport facility directory.

The twin engine aircraft was engaged in a survey flight over the region of Ajaccio under call sign 'Bengale 97', carrying one pilot and one fireman. Shortly after takeoff from Ajaccio-Campo dell'Oro Airport runway 20, while in initial climb, the pilot retracted the landing gear when the left engine failed. He initiated a left hand turn to return to runway 20 when the aircraft stalled and crashed on a the beach of Capitello about 500 metres southeast of the runway end, bursting into flames. Both occupants and a girl aged 13 were killed while four other people were seriously injured. Few days later, two of them, German tourists, died from their injuries.

During the takeoff roll, at a speed of 135 km/h, the pilot-in-command slowly started the rotation and the nose gear lifted off. Then, at a speed of 165 km/h, he lifted off more vigorously when the flight engineer retracted the landing gear. At a speed of 190 km/h, the aircraft sank back on the runway on its belly (the landing gears were partially retracted), causing both propellers to struck the ground. The aircraft slid for about 740 metres when eight seconds later, the flight engineer shut down both engines while both propellers were feathered 20 seconds later. The aircraft slid for another 300 metres then came to rest 1,670 metres from the departure point. All 32 occupants evacuated safely and the aircraft was damaged beyond repair.

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.

During the takeoff roll, at a speed of 80 knots, the twin engine aircraft deviated to the right then veered off runway and came to a halt. All 11 occupants evacuated safely while the aircraft was damaged beyond repair.

During an aborted takeoff, the airplane overran the 4,451 foot long runway, went down a hill, and struck a fence. According to the pilot, 'during the takeoff roll, the indicated airspeed needle climbed to approximately 60 knots, but then would go no further... My attempts to dislodge it by tapping on the face of the gauge were futile...I pulled back the throttles and applied full brakes...' The pilot reported that based on the existing conditions 'the airplane can accelerate from rest to rotation speed and back to rest in less than 3,500 feet.' The examination of the airplane revealed the pitot tube was internally obstructed with an insect and mud.
