Landing (descent or approach)

While descending to Mergui Airport, the crew encountered poor weather conditions with heavy rain falls. On short final, the aircraft lost height and struck the ground about 250 metres short of runway 18. On impact, the undercarriage were torn off and the aircraft slid for few dozen metres before coming to rest in a 1,2 metre deep excavation located short of runway threshold. Eight passengers were killed while 16 others were seriously injured.

After landing on runway 33 at Rosh Pina Airport, the captain thought the thrust reverser systems did not work properly so he instructed the copilot to activate them again. The aircraft failed to decelerate correctly so the captain decided to veer off runway when the aircraft struck a concrete block, lost its undercarriage and came to rest. All eight occupants escaped uninjured and the aircraft was damaged beyond repair.

The cargo flight was en route, when a fire erupted in or near the #3 engine. During subsequent emergency procedures, the flight crew pulled the fire handle first. Later, they feathered the #3 engine. The fire did not extinguish. During an attempt to land at a rural, intermediate airstrip, while the airplane was in the traffic pattern, witnesses saw fire coming from the area of the #3 engine. They stated the right wing buckled upward, and the airplane crashed. Examination of the wreckage revealed a failure of the master rod in the front bank of cylinders of the #3 engine. Metallurgical tests revealed a crack in the top of the master rod head, which had resulted from corrosion pits. The side of the master rod head was measured and found to be out of round. The master rod shank also fractured due to fatigue. The operator's training procedures and the Douglas Aircraft emergency checklist procedures, required that the engine's propeller be feathered first, and then the fire extinguishing system to be activated. According to information derived from the airplane's cockpit voice recorder, the flight crew reversed that order. The effectiveness of the fire suppression system is diminished if the propeller is not feathered first.

The pilot of the air taxi cargo flight departed his base of operations in Juneau, Alaska for a series of flights in southeast Alaska that would ultimately return him to Juneau. On the accident leg of the intended round robin, the pilot was en route from Hoonah to Elfin Cove. The flight would originate and end at sea level, and traverse a mountain pass, with minimum obstruction clearance in the pass estimated at 500 feet msl. The airplane collided with steeply rising terrain at the 1,250-foot level about one mile south of the proposed flight path. The airplane was partially consumed by a post impact fire. The operator initiated a helicopter search within two hours of the time of the accident. The helicopter pilot and his passenger both reported that the area where the accident airplane was eventually located was obscured in low clouds, and that many of the other valleys and mountain sides were covered in clouds. Low clouds persisted in the area of the crash site for the following two days.

After landing at Playa del Carmen Airport, the twin engine aircraft went out of control, veered off runway and crashed in a wooded area located along the airport. A passenger was killed and all 17 other occupants were injured. The aircraft was destroyed. It was completing a flight from Cancún, carrying 16 German tourists.

The aircraft was chartered by the Dutch Air Force (Koninklijke Luchtmacht) to fly the Dutch Air Force's brass band from Italy back to the Netherlands. The transport plane arrived at Verona-Villafranca at 13:33. Forty passengers boarded the plane and at 15:04 the Hercules took off from Villafranca for a short flight to Rimini, where it landed at 15:31. Three passengers deplaned at Rimini and the Hercules was back in the air at 15:55 heading for Eindhoven. The Hercules descended into Eindhoven and contacted Eindhoven Tower at 18:00. Eindhoven Tower cleared the flight for the approach: "Okay, you may continue descent for 1000, as number one in traffic, for a direct final course runway 04, QNH 1027." After reported the runway in sight, the Hercules was cleared to land: "610 is cleared to land runway 04, the wind from 360° 10 knots." Possibly as a result of the presence of a large number of birds near the runway, the copilot initiated a go around. Birds were ingested by both left hand engines (n°1 and 2), causing both engines to lose power. For reasons unknown the crew shut down engine n°3 and feathered the propeller. The plane then turned left and crashed off the left side of the runway. Within seconds a fire erupted which was fed by the oxygen from the airplane's oxygen system. Some emergency exits in the main cabin were unreachable because of the fire while other exits could not be opened because of twisting of the fuselage. The fact that there were a large number of passengers on board the plane was not immediately clear tot the fire fighters. It took some 23 minutes before passengers were noted in the main cabin.

Following an uneventful flight from Shimla, the crew started the descent to Kulu-Bhuntar Airport in poor visibility due to thick fog. On approach, the aircraft struck trees and crashed in a wooded area located on Mt Bandi. The aircraft was destroyed and all nine occupants were killed.

While approaching Mendi Airport, the crew encountered poor weather conditions with limited visibility due to rain falls. At an altitude of 9,200 feet, the twin engine aircraft struck the slope of a mountain located 8 km from the runway threshold. The aircraft disintegrated on impact and all 20 occupants were killed.

On final approach to San Vicente de Chucurí Airport, the twin engine aircraft struck an earth mound located few metres short of runway threshold. The aircraft went out of control and crashed in trees. All nine occupants escaped uninjured and the aircraft was damaged beyond repair.

While descending to Bamako-Senou Airport, the crew was informed about the poor weather conditions at destination with thunderstorm activity and strong crosswinds. As the visibility was estimated to be above 10 km, the crew decided to continue the approach. After landing on runway 06, the aircraft was caught by strong crosswinds and started to roll left and right, causing the right wing to struck the runway surface. Out of control, the aircraft veered off runway to the right and collided with a bunker. The right wing was torn off and the aircraft came to rest. All four crew members escaped uninjured.
