Circumstances:
As the crew was 12 minutes behind the schedule, he decided to start the takeoff procedure from an intersection and the departure was precipitated despite ATC warned the crew about the recent takeoff of a Boeing 707 from the same runway. Just after liftoff, while in initial climb, the airplane became unstable then stalled and crashed. Both pilots and a passenger were killed while 11 other occupants were injured, some of them seriously.
Probable cause:
It was determined that the crew lost control of the airplane due to wake turbulences caused by a Boeing 707 that just took off from the same runway. The crew failed to consider the warning from ATC.

Circumstances:
The descent to Bahía Blanca-Comandante Espora Airport was started by night. The crew was informed by ATC that the visibility was reduced to 200 meters due to fog which means below minima. The captain decided to attempt an approach to runway 34. After passing the middle marker, he was able to see the runway lights so he decided to continue the approach under visual mode. Shortly later, he lost visual contact when the airplane struck the ground about 25 meters short of runway threshold and 200 meters to the left of the extended centerline. On impact, the right wing was torn off and the airplane lost its undercarriage before coming to rest. All 39 occupants were evacuated safely.
Probable cause:
Wrong approach configuration on part of the captain who decided to land in below-minima weather conditions.

Circumstances:
The approach to Bangkok-Don Mueang Airport was completed by the copilot in poor weather conditions (low visibility and heavy rain falls due to tropical storm) when the ILS equipment failed. It was decided to continue the approach and at an altitude of 700 feet, the pilot-in-command was able to locate the runway lights. At this time, the aircraft was slightly too high on the glide and too far to the left. Once the altitude of 300 feet was reached on descent, the IAS was 127 knots, about five knots above the planned speed. Thus, the copilot decided to reduce the speed to 122 knots when the airplane suddenly lost height. The captain elected to regain control but it was too late. With a relative high sink rate, the airplane landed very hard, causing both main landing gear to puncture the wings. The aircraft came to rest after a course of several hundred yards. While all 75 occupants escaped uninjured, the aircraft was damaged beyond repair.
Probable cause:
Windshear is suspected.

Aircraft flight hours:

Circumstances:
Air South Flight 168 departed Atlanta at 21:07. At 21:13 the flight reported level at its assigned cruising altitude of 7,000 feet. The Beech had been cruising for eleven minutes when it attained a gradual nose down attitude due to a change in the longitudinal trim. The pilots noticed the change after about six seconds and initiated a recovery action. The horizontal stabilizer continued to move to a full nose down position. Excessive pulling force on the control column was necessary to recover from the high speed dive. The necessary stick forces for such an out-of-trim condition can exceed the capability of one pilot, and in some cases two pilots, to control. The Beech continued to descend until both wings failed at high speed, just before the airplane crashed into the ground in a near vertical attitude.
Probable cause:
An unwanted change in longitudinal trim which resulted in a nosedown high-speed flight condition that was beyond the physical capability of the pilots to overcome. The initiating element in the accident sequence could not be specifically determined. However, the design of the aircraft flight control system was conducive to malfunctions which, if undetected by the crew, could lead to a loss of control.

Circumstances:
After takeoff from Talas Airport, the pilot-in-command initiated a turn to the right heading 270° instead to the left as in the published procedures. Six minutes later, ATC transmitted several instructions but nothing concerning the track deviation. While climbing to an altitude of 3,150 meters in clouds, the airplane struck the slope of a rocky mountain and crashed 39 km from the airport. The wreckage was found few hours later and all 40 occupants were killed.
Probable cause:
The crew violated the published procedures and made a turn to the right instead of left after takeoff and continued to climb in clouds under VFR mode. In such conditions, the crew was unable to distinguish the mountain. At the time of the accident, the airplane was off track by 8,7 km. It was reported that the crew based in the Frunze region systematically violated the published procedures for this airport.

Circumstances:
While taxiing at Honolulu Airport, on a flight to Molokai, the pilot-in-command lost control of the airplane that collided with a parked Hawaii Air DC-9 registered N906H. While the DC-9 was slightly damaged, the Viscount was damaged beyond repair and the 14 occupants were uninjured.
Probable cause:
Loss of control during taxi due to the failure of the landing gear braking system. It was determined that the crew lost brakes and steering as the hydraulic system was not bled of air. The following factors were considered as contributing:
- Improper maintenance and inspection on part of the maintenance personnel,
- Inadequate preflight preparation on part of the flying crew.
