Landing (descent or approach)

On approach to Palu-Mutiara Airport, the crew encountered poor weather conditions with limited visibility due to rain falls. On final, he failed to realize his altitude was too low when the aircraft struck the slope of Mt Kalora (690 metres high) located 8 km short of runway. The aircraft was destroyed upon impact and all 12 occupants were killed.

The airplane crashed 0.8 nm south of the threshold of the runway during an ILS approach in instrument meteorological conditions. The captain was not authorized to attempt the approach and was relatively inexperienced for an approach under the weather conditions. The captain failed to adhere to acceptable standards of airmanship during two unstabilized approaches. After the unsuccessful ils approach to runway 01R, the captain should have held for improvements in the weather, requested the runway 19L ILS, or proceeded to his alternate. An operating gpws aboard the airplane would have provided continuous warning to the crew for the last 64 seconds of flight and might have prevented the accident. All 10 passengers were Mexican citizens flying to Washington DC to assist a game of the World Football Championship.

While descending to Uruapan-General Ignacio López Rayón Airport, the crew encountered poor weather conditions and limited visibility due to the night and rain falls. ATC instructed the crew to carry out an instrument approach but the pilots insisted for a visual approach to runway 02. Because the crew was unable to establish a visual contact with the runway, he decided to initiate a go-around procedure, completed a right turn and attempted a second approach few minutes later that was also abandoned for the same reasons. This time, the captain initiated a turn to the left in an attempt to make a visual approach to runway 20, which was non compliant with the published procedures. Shortly later, while at an altitude of 1,200 metres, the twin engine aircraft struck the slope of a mountain located 5,9 km northwest of the airport. The aircraft was destroyed upon impact and all nine occupants were killed.

The twin-engine turboprop aircraft had just completed a medical evacuation (MEDEVAC) flight from Coral Harbour, Northwest Territories (NWT), to Churchill, Manitoba. At 2257 central daylight saving time (CDT), the aircraft departed Churchill for a night, instrument flight rules (IFR) flight to return to the aircraft's base of operations at Thompson, Manitoba. The en route portion of the return leg was conducted at an altitude of 18,000 feet above sea level (asl). Approximately one hour after take-off, the aircraft commenced an approach to the Thompson Airport. The crew remained in radio contact with air traffic control (ATC) personnel until approximately 2359 CDT. Just after midnight (0001 CDT), the Hotel non-directional beacon (NDB), which is located 3.4 miles northeast of the Thompson Airport, stopped transmitting. Ninety minutes later, the search and rescue satellite system (SARSAT) picked up an emergency locator transmitter (ELT) signal to the northeast of the airport. Thompson Airport staff, who had been dispatched to the site of the failed navigation beacon, found the wreckage of the aircraft in and around the NDB transmitter compound. Emergency responses were initiated by various airport and local authorities.

The corporate jet's sink rate increased during short final approach. The copilot applied elevator back pressure and nose up trim. The sink rate continued to increase. The captain observed the copilot's efforts and began applying back pressure on his control yoke. Through combined efforts of both pilots they were able to increase the pitch enough that the airplane touched down on the main gear first. However, the touchdown was hard. The on-scene investigation revealed that a trip manifest container was lodged between the copilot's control yoke column and seat frame. The pilots stated the container is required to be carried in the cockpit during lights. Both pilots said there is no designated space in the cockpit to retain the container.

The aircraft was completing an ambulance flight from Rarotonga (Cook Islands) to Tahiti, carrying to Australian patients, two doctors and one pilot. On final approach to Papeete-Faaa Airport runway 04 by night, the twin engine aircraft descended too low and crashed in the sea about 6,4 km short of runway. The pilot did not send any distress call prior to impact and the aircraft struck the water surface in a flat attitude. All five occupants were killed. For unknown reasons, the pilot failed to realize his altitude was insufficient on short final. The lack of visibility and visual references were considered as contributing factors.

On final approach to Bukoba Airport, the aircraft was too low when one of its wing struck a tree. The aircraft lost height and crashed on a clinic. Both pilots were killed while there were no victims on the ground.

En route, the crew encountered technical problems and was cleared to divert to Mitú-Fabio Alberto León Bentley Airport for an emergency landing. After touchdown, the four engine aircraft went out of control, veered off runway and came to rest. All nine occupants escaped with minor injuries and the aircraft was damaged beyond repair. The nature of the technical problems remains unknown.

The approach and landing at Palana Airport were completed in strong crosswinds. The twin engine aircraft landed hard and was apparently damaged beyond repair due to structural damages. All 12 occupants evacuated safely.

En route from Lisbon to Bragança, while cruising at an altitude of 8,000 feet over clouds, the right engine suffered vibration. Few minutes later, the crew decided to shut it down and its propeller was feathered. As the crew was unable to maintain a safe altitude on one engine, he decided to descend and to attempt an emergency landing on a road. On final, the aircraft struck trees and crashed. All four occupants were slightly injured.
