Circumstances:

During the takeoff roll at Rio de Janeiro-Santos Dumont Airport, about 8 knots below V1 speed, the captain noticed a loss of power on both engines while the turbine temperature was at its maximum. In such situation, the captain decided to abort the takeoff procedure and applied brakes. It appears the aircraft failed to decelerate properly so the crew activated the emergency brakes that were effectives on the right main gear only. As the end of the runway was approaching, the captain retracted the undercarriage so the airplane sank on its belly and slid before coming to rest into the Guanabara Bay. The aircraft sank about 10 minutes later and was lost. Eight passengers were killed while 57 other occupants were injured, some of them seriously.

Circumstances:

Following an uneventful flight from Kerkyra Airport, the crew started the descent in poor weather conditions and limited visibility due to the night. On final approach in stormy weather, the airplane struck the water surface and crashed into the sea about 5 km offshore. 16 occupants were rescued while 37 others, including a crew members were killed. The wreckage sank by a depth of 12 meters but was recovered a day later and brought back onto the beach.

Probable cause:

The exact cause of the accident remains undetermined but it is believed that it was the consequence of a controlled flight into terrain (water surface) while approaching Athens-Ellinikon Airport in limited visibility due to the night and poor weather conditions.

Circumstances:

Following an uneventful flight from São Paulo-Congonhas Airport, the crew started the descent to Rio de Janeiro-Santos Dumont Airport from the north. While flying at an altitude of 5,000 feet by night and in marginal weather conditions, the crew informed ATC he just passed over AF NDB. Two minutes later, the airplane struck the slope of a mountain located near Petrópolis, about 50 km north of Santos Dumont Airport. The airplane disintegrated on impact and all 25 occupants were killed.

Probable cause:

It was determined that while descending in IMC conditions, the crew mistakenly tuned the ADF instrument to a wrong NDB, causing the airplane to follow a wrong approach path and to descend at an inappropriate altitude. The lack of visibility due to the night and clouds was considered as a contributing factor.

After landing at Aragarças Airport, the pilot-in-command started the braking procedure when he saw the presence of another airplane on the runway. He veered off runway to the right, causing the airplane to stop in a grassy area. All occupants evacuated safely and there were no injuries. The following night, two men were dispatched to guard the aircraft. A candle was lit inside the plane, causing a fire. The cabin burned out, killing both guards.

While descending to Hakodate Airport, the crew encountered poor weather conditions. At an altitude of 6,000 feet, the airplane struck the slope of Mt Yokotsu located 18 km north of Hakodate Airport. The aircraft disintegrated on impact and all 68 occupants have been killed.

Probable cause:

The flight crew mistook a point approximately 5 nautical miles north of the Hakodate NDB as being just over the Hakodate NDB, a navigation aid, and initiated their descent from an estimated altitude of 6,000 feet in an attempt to cross the high station at 2,500 feet by making a single circle. The outbound flight leg was extended westward and because of a strong southwesterly wind, the aircraft drifted further to the north than the crew expected, striking the mountain. It is so considered that the accident was the consequence of a controlled flight into terrain.
