Circumstances:
The Let L-410 departed the terminal and was approaching the runway to depart for a schedule service to Kutaisi, carrying nine passengers and a crew of two. At 1808LT, the crew of an Aeroflot Tupolev TU-134 registered CCCP-65836 was cleared for takeoff from runway 02. En route to Moscow-Vnukovo, the Tupolev was carrying 76 passengers and a crew of six. During the takeoff run, 26 seconds after it started to roll, at a speed of 195 km/h, the crew of the TU-134 sighted a Let L-410M entering the runway. The captain of the Tupolev decided to abandon the takeoff maneuver and initiated an emergency braking procedure. Spoilers were deployed and revers systems were activated. He elected to turn to the left to reach an exit taxiway. In the same time, the crew of the Let saw the Tupolev coming from their right and increased engine power to move forward. Seven seconds after the crew of the Tupolev rejected takeoff, at a speed of 216 km/h, the right wing of the Tupolev struck the Let that was destroyed upon impact. The Tupolev rolled for about 514 meters then veered off runway to the left and came to rest 48 meters to the left of its centerline. All 82 people on board the TU-134 escaped uninjured while all 11 people on board the Let were killed.
Probable cause:
It was determined that the collision was the consequence of a series of errors made by the crew of the Let L-410 who failed to follow ATC and ground controllers instructions regarding taxiing procedures prior to takeoff, which led them to enter the runway when he was not authorized to do so. A poor management in flights organization at Sukhumi Airport remains a contributing factor as well as few procedures violation on the part of ATC and ground controllers, among others concerning the use of a non-standard phraseology which may create confusion to the crew.

Circumstances:
On final approach to Santa Marta-Simón Bolívar Airport, the crew failed to realize his altitude was insufficient when the airplane stuck the ground few dozen meters short of runway threshold. The aircraft bounced and landed hard on runway. Upon touchdown, the left main gear was partially torn off. The aircraft went out of control, veered off runway to the left and came to rest. All 50 occupants were evacuated safely while the aircraft was damaged beyond repair.

Circumstances:
The single engine airplane departed Toko on a flight to Uchur, carrying three passengers and a crew of two. On board were two unauthorized passengers who wanted to be dropped by the River Algoma to go fishing. The crew made a stop and dropped both passengers by the river then decided to takeoff again. But the available distance of 150-180 meters was insufficient and the aircraft's speed at takeoff was too low so it struck the river surface and crashed inverted in shallow water. All three occupants escaped uninjured while the aircraft was damaged beyond repair.
Probable cause:
Poor judgment on part of the crew about the distance available at takeoff. Insufficient takeoff speed was a contributing factor as well as the uneven/rough terrain.

He initiated an emergency braking maneuver but the aircraft was unable to stop within the remaining distance. It overran, went through a concrete wall and eventually collided with a bulldozer. Three passengers and a crew member were killed while 26 other occupants were injured.

Circumstances:
Pan Am Flight 759 was a scheduled flight from Miami (MIA) to Las Vegas (LAS), with an en route stop at New Or1eans (MSY). At 15:58:48 Boeing 727 "Clipper Defiance" taxied from its gate at the New Orleans International Airport. Before leaving the gate, the flightcrew had received ATIS message Foxtrot which read in part "....time one eight five five Zulu, weather, two thousand five hundred scattered, two five thousand thin broken, visibility six miles in haze, temperature niner zero, wind two four zero at two, winds are calm altimeter three zero zero one...". The flightcrew requested runway 10 for the takeoff and ground control cleared the flight to taxi to runway 10. At 15:59:03, the first officer requested a wind check. Winds were 040 degrees at 8 knots. At 16:02:34, while Flight 759 was taxiing to runway 10, the crew heard a transmission from ground control, advising another airplane of low level wind shear alerts in the northeast quadrants of the airport. At 16:03:33, the first officer requested another wind check. Ground control replied, "Wind now zero seven zero degrees at one seven... peak gusts two three, and we have low level wind shear alerts all quadrants, appears to be a frontal passing overhead right now, we're right in the middle of everything." The captain then advised the first officer to "...let your airspeed build up on takeoff..." and said that they would turn off the air conditioning packs for the takeoff, which would enable them to increase the EPR's on engines Nos. 1 and 3 to 1.92. The flightcrew completed the takeoff and departure briefings and turned onto the active runway for takeoff. At l6:06:22, Flight 759 informed the tower that it was ready for takeoff. The local controller cleared the flight for takeoff, and the first officer acknowledged the clearance. About 16:07:57, the Boeing 727 began its takeoff. According to witnesses, the airplane lifted off about 7,000 feet down runway 10, climbed in a wings-level attitude, reached an altitude of about 100 feet to 150 feet above the ground (AGL), and then began to descend towards trees. The airplane crashed into a residential area and was destroyed during the impact, explosion, and subsequent ground fire. Eight persons on the ground were killed.
Probable cause:
The airplane's encounter during the lift-off and initial climb phase of flight with a micro-burst induced windshear which imposed a downdraft and a decreasing headwind, the effects of which the pilot would have had difficulty recognizing and reacting to in time for the airplane's descent to be arrested before its impact with trees. Contributing to the accident was the limited capability of current ground based low level windshear detection technology to provide definitive guidance for controllers and pilots for use in avoiding low level wind shear encounters.

Circumstances:
The four engine airplane departed Moscow-Sheremetyevo Airport on a regular schedule service to Freetown with an intermediate stop in Dakar. After takeoff from runway 24R at Sheremetyevo Airport, while in initial climb, the crew raised the landing gear. Eight seconds later, the fire alarm for engine n°1 sounded. The crew shut down the engine in accordance with the Flight Manual and used the three stages of fire suppression systems. Thirty seconds later, the fire alarm coupled to the engine n°2 sounded as well. The same procedure was adopted for the second engine and the crew declared an emergency. At a speed of 320 km/h and a height of 160 meters with the undercarriage retracted and the flaps down at 30°, the pilot-in-command initiated a right turn. Unfortunately, he was unable to maintain a safe altitude and the airplane lost speed and height while in a high angle of attack. From a height of 75 meters, the airplane stalled, banked left to 70° then nosed down 20° and crashed in a wooded area located in Mendeleyevo, about 11,4 km northwest of the airport. The aircraft disintegrated on impact and all 90 occupants were killed.
Probable cause:
It was determined that both fire alarms on engines n°1 and 2 were false. Hot air from a ruptured pipe of the air conditioning system had blown on the temperature sensors.
