Takeoff (climb)

Witnesses observed the aircraft departing from runway 14 with a rolling start. They said the aircraft rotated at the departure end of the runway and remained in ground effect with an excessive, nose high attitude. It then struck the airport perimeter fence, a barrier wall, and power lines. Power line wires were dragged through a residential area, resulting in additional damage. The airplane then crashed in a pasture and burned. Investigation revealed the airplane had been loaded to a gross weight (GW) of 50,870 lbs. Its maximum GW was limited to 48,000 lbs at sea level with the use of antidetonation injection (ADI) fluid and 40,900 lbs without ADI. Density altitude at the airport was 6200 feet. For conditions at the airport, maximum GW for takeoff with ADI and 15° of flaps was 43,205 lbs; without ADI and with 13 degrees of flaps, maximum GW was 38,909 lbs. The airplane flaps were found in the retracted position, but there was no performance data for takeoff with the flaps retracted. No ADI fluid was found in the line to the right engine, although it was intact; the ADI tank was destroyed; the ADI line to the left engine was damaged. The airplane was being flown under provision of a ferry permit, which did not provide for the cargo or the two passengers that were aboard. The first pilot (PIC) had accrued about 8 hours of flight experience in the make and model of airplane.

The aircraft was completing a positioning flight from Asunción to Campinas on behalf of Alas Paraguayas, under flight number ALA028. As there was no cargo on board, the crew decided to make profit of the situation to perform training upon takeoff. During the takeoff roll on runway 02, at Vr speed, the captain reduced the power on engine n°1 and after liftoff, he reduced power on engine n°2. With the undercarriage still down and the flaps at 15°, the aircraft became unstable, lost height and crashed in the district of Mariano Roque Alonso, about 1,500 metres past the runway end. The aircraft was destroyed by impact forces and a post crash fire and all four occupants were killed as well as 18 people on ground, most of them children taking part to a volleyball game.

The aircraft departed at night from runway 4R on a flight to transport mail. The pilot-in-command (PIC) was in the left seat, a pilot-rated cargo loader was in the right seat, and another cargo loader was aboard the aircraft, but was not in a seat. During takeoff, the aircraft entered a turn and flew into gradually rising terrain. The initial impact point was about 15 feet higher than the runway elevation and about 0.3 miles abeam the departure end of the runway. Investigation revealed that the company allowed pilot-rated cargo loaders to fly the aircraft from the right seat during positioning and ferry flight segments (to build multiengine flight time) as part of their compensation. There was evidence that at the time of the accident, the aircraft was being piloted on this flight from the copilot's position. The right side of the instrument panel was equipped with only EGT gauges (no flight instruments on the copilot's side). There were cloud layers in the vicinity, no moon illumination, and no visible ground lighting in the direction of flight. No preimpact mechanical malfunction or failure was identified during the investigation. Except at the pilot and copilot positions, the airplane had no other seat and/or restraint system. The operator stated that the pilot was not authorized to carry company personnel or passengers without the required seating.

Shortly after takeoff from Johannesburg-Oliver Reginald Tambo Airport, while climbing, the twin engine aircraft went out of control and crashed near Boksburg, about 5 km south of the airport. Both occupants were killed.

The aircraft was completing a cargo flight from Kinshasa to Kahemba, carrying two passengers, four crew members and a load of food and basic necessities. During the takeoff roll, at a speed of 204 km/h, the pilot-in-command pulled up the control column to start the rotation but the aircraft failed to respond. The crew decided to abort the take off procedure but this decision was taken too late. Unable to stop within the remaining distance (the runway is 1,700 metres long), the aircraft overran, rolled for about 240 metres and came to rest in the district of Simbazikita, bursting into flames. A crew member was killed while five other occupants were injured. On ground, at least 297 people were killed while 253 others were injured, some seriously.

After takeoff from Novy Bor Airfield, while climbing to a height of about 10 metres, the aircraft nosed up. The pilot reduced the engine power when the aircraft stalled and crashed on the runway about 150 metres from its end. All 14 occupants evacuated safely while the aircraft was damaged beyond repair. It was reported that the CofG was well beyond the aft limit.

The aircraft departed Rancagua-de la Independencia Airport on a local skydiving mission. During the takeoff roll, the captain noticed a unknown technical problem and abandoned the procedure. The aircraft went out of control, veered off runway and came to rest. A passenger was killed.

The captain initiated a takeoff on runway 04L, which was covered with patches of ice and snow. The wind was from 330 degrees at 11 knots. Before receiving an 80-knot call from the 1st officer, the airplane began to veer to the left. Subsequently, it went off the left side of the runway and collided with signs and an electric transformer. Investigation revealed evidence that the captain had overcontrolled the nosewheel steering through the tiller, then applied insufficient or untimely right rudder inputs to effect a recovery. The captain abandoned an attempt to reject the takeoff, at least temporarily, by restoring forward thrust before the airplane departed the runway. The current Boeing 747 operating procedures provide inadequate guidance to flightcrews regarding the potential for loss of directional control at low speeds on slippery runways with the use of the tiller. Current Boeing 747 flight manual guidance was inadequate about when a pilot should reject a takeoff following some indication of a lack of directional control response. Improvements in the slippery runway handling fidelity of flight simulators used for Boeing 747 pilot training were considered to be both needed and feasible.

On December 18, 1995, at 1730 central standard time, a Beech B200, N231RL, was substantially damaged, during takeoff near Ingleside, Texas. The commercial pilot and his passenger were not injured. The airplane was owned by R.A. Beeler Leasing Company, of Carrizo Springs, Texas, and operated by Western Airways Inc., of Houston, Texas. The airplane was stolen from the West Houston Airport at 1600. Visual meteorological conditions prevailed and no flight plan was filed. According to U.S. Customs officials, the operator's chief mechanic reported the aircraft stolen as soon as the airplane was broken into by the two occupants. A U.S. Customs airplane was vectored to intercept the stolen airplane. The owner of the airplane reported there was approximately 800 pounds of fuel aboard at the time the airplane was stolen. The airplane was intercepted as it was landing at the T.P. McCampbell Airport, near Ingleside, Texas. The Customs aircraft landed and blocked the single 4,996 foot runway. While attempting to takeoff to evade law enforcement personnel, the airplane impacted a fence, crossed a ditch, and came to rest in a swamp. The two occupants of the airplane jumped out and ran. The pilot's son was captured, but the pilot was not apprehended. The following items were found in the airplane: bolt cutters, 2 masks, loaded weapons, the pilot's wallet, and charts and maps indicating that the planned destination of the flight was near Cartagena, Colombia. The nose landing gear collapsed, the left wing sustained structural damage, and the pressure bulkhead was punctured.

The pilot was attempting to transport by-pass mail from Nome to Gambell, Alaska. The pilot stated that the takeoff run was normal until he rotated the nose of the airplane to lift off. The pilot said the airplane pitched up and he had to apply full forward control yoke pressure while he adjusted the pitch trim to nose down. The airplane rolled to the left and the pilot used the rudders to level the wings prior to impact. The information provided by the company, the FAA, and the post office, indicate that the airplane weighed 10,114 pounds at the time of the takeoff. The certificated maximum gross weight was 10,100 pounds. A weight and balance calculation, based upon information obtained from the company and the placarded limits on the airplane, showed a center of gravity of 121.9 inches. The center of gravity limits shown in the airplane manual are 113 to 120.5 inches. The wreckage examination showed that the elevator trim indicator was indicating full nose up trim.
