Landing (descent or approach)

The aircraft departed Broome on a charter flight to Koolan Island, WA. At about 0645 Western Standard Time1, when the aircraft was at an altitude of about 9,500 feet, the pilot noticed a drop in the engine torque indication with a corresponding drop in the engine oil pressure indication. The pilot increased the power lever setting but the engine torque and oil indications continued to reduce, all other engine indications were normal. During an interview with the Australian Transport Safety Bureau (ATSB) the pilot stated that he felt a power loss associated with the drop in indicated engine torque. The pilot diverted to the nearest airstrip, which was Beagle Bay, WA. He stated that the low oil pressure warning light illuminated so he shut the engine down and prepared for an emergency landing. The pilot reported that on the final approach to the airstrip he realized that the aircraft was too high and its airspeed was too fast. The aircraft touched down about mid way along the runway and overran the end of the runway by about 200 metres. The aircraft impacted a mound of dirt, coming to rest upside down. The pilot, who was the only occupant sustained minor injuries. Examination of the aircraft by a third party and inspection of the photographs taken of the accident site, revealed that the engine, left main gear and nose gear had separated from the airframe during the accident sequence. There was a significant amount of oil present on the underside of the aircraft, indicating that the oil had leaked from the engine during operation. The
engine was removed from the accident site as an assembly by a third party. The propeller was removed and the engine was shipped to an engine overhaul facility where a disassembly and
examination was conducted under the supervision of the ATSB.

The aircraft departed Nairobi on a humanitarian mission to Moba, carrying 18 passengers and 4 crew members on behalf of the United Nations Organization. After touchdown, the left main gear collapsed. The aircraft veered off runway to the left and came to rest in a marsh field. All 22 occupants escaped uninjured and the aircraft was damaged beyond repair. It appears that the pilot-in-command was distracted during the last segment by pedestrians at the runway threshold and the aircraft landed hard.

The flight was scheduled to pick up cargo at the destination airport and then deliver it to another location. During the descent and 14 minutes before the accident, the airplane encountered a layer of moderate rime ice. The captain, who was the pilot flying, and the first officer, who was the monitoring pilot, made multiple statements which were consistent with their awareness and presence of airframe icing. After obtaining visual flight rules conditions, the flight crew canceled the instrument flight rules clearance and continued with a right, circling approach to the runway. While turning into the base leg of the traffic pattern, and 45 seconds prior to the accident, the captain called for full flaps and the engine power levers were adjusted several times between 50 and 95 percent. In addition, the captain inquired about the autopilot and fuel balance. In response, the first officer stated that he did not think that the spoilerons were working. Shortly thereafter, the first officer gave the command to add full engine power and the airplane impacted terrain. There was no evidence of flight crew impairment or fatigue in the final 30 minutes of the flight. The cockpit voice recorder showed multiple instances during the flight in which the airplane was below 10,000 feet mean sea level that the crew was engaged in discussions that were not consistent with a sterile cockpit environment, for example a lengthy discussion about Class B airspeeds, which may have led to a relaxed and casual cockpit atmosphere. In addition, the flight crew appears to have conducted checklists in a generally informal manner. As the flight was conducted by a Part 135 operator, it would be expected that both pilots were versed with the importance of sterile cockpit rules and the importance of adhering to procedures, including demonstrating checklist discipline. For approximately the last 24 seconds of flight, both pilots were likely focusing their attention on activities to identify and understand the reason for the airplane's roll handling difficulties, as noted by the captain's comment related to the fuel balance. These events, culminating in the first officer's urgent command to add full power, suggested that neither pilot detected the airplane's decaying energy state before it reached a critical level for the conditions it encountered. Light bulb filament examination revealed that aileron augmentation system and stall warning lights illuminated in the cockpit. No mechanical anomalies were found to substantiate a failure in the aileron augmentation system. No additional mechanical or system anomalies were noted with the airplane. A performance study, limited by available data, could not confirm the airplane's movements relative to an aileron augmentation system or spoileron problem. The level of airframe icing and its possible effect on the airplane at the time of the accident could not be determined.

The four engine aircraft departed Khartoum Airport at 0738LT on a cargo flight to Heglig, carrying four crew members and a load consisting of 13 tons of various goods. On final approach to Heglig Airport, the aircraft was too low. It collided with obstacles and a concrete block located 16 metres short of runway threshold and housing an element of the approach light system. The aircraft bounced, nosed down and landed nose first 52 metres further. After a course of 183 metres, a tyre on the right main gear burst. The captain instructed the flight engineer to activate the reverse thrust systems but the flight engineer did not check the power levers. The aircraft veered off runway to the left, lost its left main gear and came to rest. All four occupants escaped uninjured while the aircraft was damaged beyond repair.

On final approach to Kinshasa-N'Djili Airport, the crew encountered poor weather conditions with limited visibility due to heavy rain falls. After touchdown on runway 06, the aircraft passed through standing water when control was lost. It veered off runway to the right, lost its undercarriage and came to rest in a grassy area. All four occupants escaped uninjured while the aircraft was damaged beyond repair.

While approaching Vomo Island, near Viti Levu Island, Fiji, the single engine aircraft crashed into the sea few dozen metres offshore. All six occupants were slightly injured while the aircraft was damaged beyond repair.

American Airlines Flight AA331, a Boeing 737-823 in United States registration N977AN, carrying 148 passengers, including three infants, and a crew of six, was being operated under the provisions of 14 Code of Federal Regulations (CFR) Part 121. The aircraft departed Miami (KMIA) at 20:22 Eastern Standard Time (EST) on 22 December 2009 (01:22 Universal Coordinated Time (UTC) on 23 December 2009) on an instrument flight rules (IFR) flight plan, on a scheduled flight to Norman Manley International Airport (NMIA), ICAO identifier: MKJP, Kingston, Jamaica. The aircraft landed at NMIA on runway 12 in the hours of darkness at 22:22 EST (03:22 UTC) in Instrument Meteorological Conditions (IMC) following an Instrument Landing System (ILS) approach flown using the heads up display (HUD) and becoming visual at approximately two miles from the runway. The aircraft touched down at approximately 4,100 feet on the 8,911 foot long runway in heavy rain and with a 14 knot left quartering tailwind. The crew was unable to stop the aircraft on the remaining 4,811 feet of runway and it overran the end of the runway at 62 knots ground speed. The aircraft broke through a fence, crossed above a road below the runway level and came to an abrupt stop on the sand dunes and rocks between the road and the waterline of the Caribbean Sea. There was no post-crash fire. The aircraft was destroyed, its fuselage broken into three sections, while the left landing gear collapsed. The right engine and landing gear were torn off, the left wingtip was badly damaged and the right wing fuel tanks were ruptured, leaking jet fuel onto the beach sand. One hundred and thirty four (134) passengers suffered minor or no injury, while 14 were seriously injured, though there were no life-threatening injuries. None of the flight crew and cabin crew was seriously injured, and they were able to assist the passengers during the evacuation.

Following an uneventful flight from Surabaya-Juanda Airport, the crew started a night approach to Ujung Pandang-Sultan Hasanuddin Airport (Makassar). On short final, at a height of 50 feet, the aircraft descended fast and landed nose first. A tyre burst on impact and the aircraft was stopped following a normal landing course. All 108 occupants evacuated safely and the aircraft was damaged beyond repair due to fuselage damages.

On Sunday December 20, 2009 at approximately 1700 UTC a fixed wing, multi engine, Fairchild SA-227AC Metro-liner III aircraft landed at Cap Haïtien Int’l Airport, Haiti, with its landing gear retracted. The pilot reported on two occasions whilst the aircraft was configured with flaps and gear extended, upon reduction in power preparing to land, the aircraft had a very high nose up attitude. The pilot further stated that after two go around, the decision was made to land the aircraft with its landing gear retracted. The aircraft landed on Runway 05. According to the pilot, the crew and all 19 passengers onboard suffered no injuries.

After landing at Tonj Airfield, the aircraft that was unable to stop within the remaining distance. It overran and came to rest against houses. All 41 occupants escaped uninjured while a woman was killed on the ground. The aircraft departed Juba on a charter flight to Tonj, carrying security personnel from the Presidency who should prepare the next visit of the President of South Sudan in Tonj.
