Circumstances:
The crew was performing a cargo flight from Montevideo to Buenos Aires on behalf of DHL. The aircraft departed runway 24 at Montevideo-Carrasco Airport at 1945LT and the crew was cleared to climb to FL080. While reaching a height of 4,500 feet, the aircraft entered an uncontrolled descent and crashed in the sea at a speed of 570 knots which caused its disintegration off Flores Island. Few debris were found the following day floating on water but the main wreckage was localized two weeks later about one NM south of Flores Island. The CVR was found on 02AUG2012 but was unreadable as the content was concerning the last 30 minutes of the precedent flight. On 11FEB2013, fishermen found the cargo door in their fishnet. No trace of the cargo nor the crew was ever found.
Probable cause:
Investigations determined that both engines were running normally at impact, that no propeller blades were lost during descent, that fuel was not contaminated and that no problems occurred on the on electrical system. Meteorological Office confirmed that severe icing conditions prevailed at the time of the accident between FL010 and FL150. The loss of control was the consequence of erroneous indications of the flight instruments, associated with the possible formation of crystalline ice on the aircraft' structure, causing a loss of situational awareness of the crew.

Circumstances:
Following an uneventful flight from Santa Cruz-El Trompillo Airport, the crew started the descent to Trinidad-Jorge Heinrich Arauz Airport runway 14. On approach, the crew encountered poor visibility due to smoke coming from forest fires. In a visibility estimated between 300 and 500 feet, the aircraft descended too low, impacted trees and crashed in a wooded area located 8 km short of runway. The wreckage was found 3 days later. A passenger was slightly injured while 8 other occupants were killed.

Circumstances:
After touchdown on runway 19R at Oslo-Gardermoen Airport, while decelerating to a speed of 60 knots, the aircraft deviated to the right. At a speed of 40 knots, it impacted a snow berm then rotated to the right and came to rest in deep snow with its both propellers and the nose damaged. All 11 occupants evacuated safely while the aircraft was considered as damaged beyond repair.
Probable cause:
Comprehensive technical examination of the nose wheel steering on OY-NPB uncovered no single causal factor, but some indications of unsatisfactory maintenance. Irregularities that alone or in combination could have caused a temporary fault with the steering were present. The Accident Investigation Board believes that a temporary fault caused the nose wheel to unintentionally lock itself in a position towards the right. No other defects or irregularities that could explain why the aircraft veered off the runway were found. The AIBN reported that the same fault had occurred 6 days earlier as well, during that encounter the captain managed to disconnect nose wheel steering quickly enough to regain control. Maintenance could not replace the fault and the aircraft was released to service.

On approach to Rurrenabaque, following an uneventful flight from San Borja, the crew encountered problems with the landing gear which failed to lock down. As all three green lights were not ON on the cockpit panel, the Captain decided to divert to La Paz-El Alto Airport where rescue teams were alerted. After touchdown, the left main gear collapsed. The aircraft veered off runway to the left before coming to rest in a grassy area. All eight occupants escaped uninjured and the aircraft was damaged beyond repair.

Aircraft flight cycles:

Circumstances:
The aircraft departed Belfast City Airport (EGAC) on an international scheduled passenger service to Cork Airport (EICK). Low Visibility Procedures (LVP) were in operation at the destination. The aircraft carried out two ILS1 approaches, each followed by a missed approach. The aircraft then entered a holding pattern following which a third ILS approach was made to Runway (RWY) 17. The approach was continued below Decision Height (200 ft) and a missed approach was initiated. Approaching the runway threshold, the aircraft rolled to the left followed by a rapid roll to the right during which the right wingtip contacted the runway surface. The aircraft continued to roll and impacted the runway in a fully inverted position. The aircraft departed the runway surface to the right and came to rest in soft ground. A significant quantity of mud entered the aircraft through a fracture in the roof, partially filling the cabin. Six persons (including the two Flight Crew members) were fatally injured, four were seriously injured and two received minor injuries. The propeller blades on both engines were severely damaged; three of the four propeller blades on the right-hand engine detached during the impact sequence. Fire occurred in both engines after impact. These fires were extinguished expeditiously by the Airport Fire Service.
Probable cause:
Loss of control during an attempted go-around initiated below Decision Height (200 feet) in Instrument Meteorological Conditions.
The following factors were considered as significant:
- The approach was continued in conditions of poor visibility below those required.
- The descent was continued below the Decision Height without adequate visual reference being acquired.
- Uncoordinated operation of the flight and engine controls when go-around was attempted
- The engine power-levers were retarded below the normal in-flight operational range, an action prohibited in flight.
- A power difference between the engines became significant when the engine power levers were retarded below the normal in-flight range.
- Tiredness and fatigue on the part of the Flight Crew members.
- Inadequate command training and checking.
- Inappropriate pairing of Flight Crew members, and
- Inadequate oversight of the remote Operation by the Operator and the State of the Operator.

Circumstances:
Following an uneventful flight, the twine engine aircraft approached Andahuaylas Airport and landed normally on runway 03. After touchdown, while decelerating to a speed of about 40 knots, the aircraft started to deviate to the left. The crew counteracted but the aircraft continued to the left, veered off runway, rolled through a grassy and eventually came down a four meters high embankment before coming to rest. While all 19 occupants escaped uninjured, the aircraft was damaged beyond repair.
Probable cause:
It appears that the loss of directional control after touchdown was caused by the failure of the brake systems. The aircraft had already several technical problems with its brake systems previous to the flight, and maintenance was performed by technicians the day before the accident. For unknown reasons, the problem was resolved but no feedback or troubleshooting was performed on part of the technicians or the crew. The Captain was aware of the problem and took the decision to complete the flight despite the risk the problem may persist or happen again.

Circumstances:
Following an uneventful flight from Lima, the crew continued the approached while the aircraft was unstabilized. Upon touchdown on runway 07, the aircraft landed relatively hard then bounced three times when the crew retracted the landing gear. The aircraft slid on its belly for about 600 metres before coming to rest. All nine occupants escaped uninjured while the aircraft was damaged beyond repair.
Probable cause:
Erroneous retraction of the landing gear following three bounces on the runway due to an unstabilized final approach and poor crew resource management.
Contributing factors were:
- Although the descent and landing checklists were followed, the crew did not review stabilized approach criteria or procedures for a possible controlled flight into terrain and did not take into consideration the possibility of any go around procedure
- Several call-outs were non-standard while others were missing
- Descent was continued under visual flight rules, approach was unstabilized and not detected by crew
- Speed was too high on touch down while the power levers were not into idle position
- Lack of corrective action on part of the crew when the aircraft was bouncing
- Loss of situational awareness led to the retraction of the landing gear.

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.
