Circumstances:
Shortly after takeoff from runway 17 at Santo Domingo-Las Américas Airport, while in initial climb, the airplane banked right and crashed in a wooded area. A crew member and a passenger were killed while 28 other occupants were injured. The aircraft was destroyed.
Probable cause:
It is believed that the loss of control was caused by the failure of the right engine shortly after liftoff.

Circumstances:
The airplane was cleared of snow prior to departure but as it was snowing continuously, the aircraft was again covered by snow between the moment it was deiced and the takeoff procedure. During the takeoff roll in poor weather conditions (snowfall and poor visibility), the pilot-in-command started the rotation. The aircraft lifted off and climbed for few meters when the left wing dropped, causing the left main gear to struck the runway surface. The airplane landed back and the crew decided to attempt an emergency braking procedure. Unable to stop within the remaining distance, the aircraft overran and the left wing collided with the building of a meteorological post located 25 metres behind the runway threshold. All 3 crew and 14 passengers escaped unhurt.
Probable cause:
It was determined that the aircraft was contaminated with snow during the takeoff procedure and that the stabs were positioned in a -5,9° angle instead of the prescribed -3,9°.

Circumstances:
The twin engine airplane departed runway 23 at Geneva-Cointrin Airport at 0903LT. During initial climb in limited visibility due to foggy conditions, the crew encountered technical problems with instruments and the airplane completed several turns at a height between 10 and 40 meters. The crew spotted a building of nine floors and elected to make an evasive manoeuvre when the airplane stalled and crashed on a railway track located in Vernier, about three km from the airport. The accident occurred about two minutes after takeoff. At the time of the accident, the horizontal visibility was 500 meters, the vertical visibility 65 meters with a runway visual range of 750 meters for runway 23.
Probable cause:
Investigations determined that after departure, the pilots were confronted with various technical issues on several instruments. Indeed, the crew had started the flight under instrument flight rules but was forced to continue under VFR mode, which was impossible due to the lack of visibility caused by the presence of fog. The aircraft maintenance did not comply with the published requirements due to corrosion detected on the bearings of the electrical turn indicator that led to the assumption that this instrument was not working at takeoff, and probably for a long time. In addition, the artificial horizon was blocked at the time of impact and investigators believe that this instrument was partially deficient at the time of departure. The pilot-in-command accumulated 3,381 flight hours in total but had only 45 minutes of experience on this type of aircraft. The copilot had a total of 2,990 flying hours including 1,400 on type. Given the presence of fog, the pilot's lack of experience and the malfunctioning of two vital instruments, the crew should not have started the flight, especially since neither pilot had a valid license under IFR mode.

Circumstances:
After takeoff from Davis Monthan AFB, the four engine airplane encountered difficulties to gain height. It struck power cables, stalled and crashed in flames. All three occupants were injured while the aircraft was destroyed.
Probable cause:
Inadequate preflight preparation on part of the crew. The following contributing factors were reported:
- Collision with wires,
- Lack of familiarity with aircraft,
- Failed to abort takeoff,
- Gust locks engaged,
- Operational supervisory personnel: inadequate supervision of flight crew,
- Unqualified person operated aircraft,
- Airport conditions,
- Checklist: failed to use,
- Downwind,
- Mechanic acting as copilot,
- 3,060 feet soft dirt strip.

Circumstances:
Shortly after liftoff from Mammoth Lakes-Yosemite Airport, while in initial climb, both propellers oversped. As the airspeed was insufficient, the aircraft stalled and crashed in flames near the airport. The aircraft was totally destroyed and all five occupants were killed.
Probable cause:
Inadequate preflight preparation on part of the pilot. The following contributing factors were reported:
- Propeller and accessories: hydraulic pitch control mechanism,
- Lack of action on part of the pilot,
- Failed to maintain flying speed,
- Propeller oversped due to congealed oil,
- The pilot failed to exercise props checks before takeoff.

Circumstances:
The crew was engaged in several flights between Shalkar and Yuzhnyy, carrying oil field workers. After takeoff from Yuzhnyy, the crew decided to make a stop in Bozoy but there was no passengers to embark so it was decided to continue quickly. Shortly after takeoff, while flying at a relative low height in limited visibility, the single engine airplane struck a radio mast (160 meters high) located near Bozoy. The airplane embedded in the mast at a height of 85 meters. Few debris fell down and all three occupants were ejected and killed.
Probable cause:
It was determined that the crew precipitated the departure from Bozoy without checking weather conditions and flight conditions. The following contributing factors were reported:
- Poor flight planning,
- Marginal weather conditions with low clouds, patches of fog and limited visibility,
- The passenger was illegally on board,
- The crew failed to communicate with ATC,
- Insufficient altitude,
- Wrong decisions.
