Circumstances:
The pilot and the passenger, a photographer, departed Vancouver at 0911LT with 5.5 hours of fuel to conduct a VFR aerial photographic flight over the Arrow Lakes area. At 1420LT, the aircraft entered the circuit at Revelstoke Airport to refuel and to allow the photographer to change camera film. The pilot reportedly selected the landing gear down as the aircraft turned base and heard the gear clunk into position. When the aircraft turned final however, the red in-transit light was illuminated and the nose gear was not visible in the mirror. The pilot selected the gear lever up and down a couple of times but the gear did not extend. When the pilot advanced the throttles to conduct an overshoot, both engines surged and sputtered. The pilot retarded the throttles and conducted a gear-up landing in a grassy area off the end of runway 30. During the landing, the dry 8-inch high grass caught fire. Both occupants escaped from the aircraft that was destroyed by ground fire.

Circumstances:
Following an uneventful flight (service UP353) from Nassau, the crew started the descent to Governor’s Harbour. After landing on runway 15, the left main gear collapsed. The aircraft slid for few dozen metres then turn slightly to the left and came to rest on the main runway. All 51 occupants evacuated safely, nevertheless, few passengers suffered minor injuries. The aircraft was damaged beyond repair.
Probable cause:
The probable Cause has been determined as an over-center Torque Link condition that culminated in a single cycle failure of the cylinder. The over center torque links condition occur as a result of the over extension of the shock strut.
Possible Contributory factors to the over extension of the shock strut includes:
Possible Cause for Loss of Damping
• The failure to install the dampening ring when the landing gear was assembled.
• Improper servicing of the landing gear shock strut with Mil-H-5606 hydraulic fluid plus nitrogen during initial assembly.
• Improper servicing of landing gear shock strut during line maintenance and inadequate post servicing follow up per AMM Chapter 12. See attached report Appendix A-30 From Bombardier
• Under-serviced shock strut (low oil volume)
• A broken damper ring
• No damper ring
• Disengaged damper ring.

Circumstances:
The aircraft ran off runway 30 at the Casas de los Pinos aerodrome while landing. The aircraft, used for parachuting operations, was making a reconnaissance flight before the parachuting flights, which were scheduled for later. According to the pilot's statement, during the flare, and before touching down, a gust of wind lifted the left wing. The pilot used left rudder and tilt to try to level the aircraft, but could not keep it from exiting the runway. As stated by the pilot, the approach was performed without flaps, at a speed of 70 knots and with the aft gear locked. The aircraft ended up 25 metres from the edge of the runway on a heading of 190°, resting on its lower fuselage, which was damaged along its underside, as were the left aileron and the horizontal stabilizer. The right main landing gear was bent outward, the left gear had detached and was 30 metres away from the aircraft, and the propeller had detached at the reduction gearbox and was next to the aft landing gear to the left of the aircraft. Both occupants were able to exit the aircraft under their own power. The pilot received a slight injury to his chin and the passenger was unhurt.
Probable cause:
It is not known why aircraft EC-JOE left runway 30 during the landing, though it seems obvious that the aircraft's path was altered while it was flying at a low altitude. The possibility that a technical problem with the aircraft caused the accident has been ruled out. It has not been possible to confirm if the wind was gusting at the aerodrome at the time of the accident, though even gusty conditions should not have affected control of the aircraft since its airspeed was high enough with respect to the stall speed.

Circumstances:
On 9 April 2007, at 1703 Western Standard Time (WST), the main landing gear from a Beech Super King Air 200 aircraft, registered VH-SGT, collapsed on landing at Perth airport. Approximately two hours earlier, the aircraft was chartered to fly from Perth to Mount Hale, WA when shortly after takeoff from Perth the aircraft experienced a malfunction of the landing gear system. The main wheels and nose gear had become jammed and were unable to fully retract when selected up by the pilot. The pilot completed the emergency checklist actions contained in the Aircraft Flight Manual, but was unable to retract or extend the gear using either the automated control or the manual emergency system. The pilot then requested assistance from a passenger to operate the manual emergency extension system. The landing gear remained jammed despite the additional force applied to the lever from the passenger. The pilot contacted air traffic services and requested further assistance from company engineering personnel to visually assess the extension state of the landing gear. Two aerodrome passes were completed throughout the troubleshooting exercise and the pilot remained in radio contact with both groups during this phase. Following the flyovers and after holding over Rottnest Island at 5,000 ft for a period of approximately two hours, the pilot flew the King Air back to Perth airport. With the gear still jammed in the partially retracted position, both the left and right main landing gear assemblies collapsed after the aircraft touched down on Runway 24. The aircraft was substantially damaged as a result of the collapse (Figure 1). The airport Rescue and Fire Fighting (RFF) services and other relevant agencies had been alerted and were waiting in response when the King Air landed. No injuries were sustained by the pilot or any of the nine passengers on board.
Probable cause:
From the evidence available, the investigation revealed that two major system components had failed which could have prevented the Beechcraft Super King Air 200 landing gear from properly retracting after takeoff. The following findings with respect to those failed landing gear system components should not be read as apportioning blame or liability to any particular organisation or individual.
Contributing safety factors:
• The left torque tube support bearing had not been lubricated and had seized due to the accumulation of dirt and grit contaminants that had migrated from the external service environment and into the bearing.
• The geared components within the right main landing gear actuator prematurely failed.
Other safety factors:
• The aircraft manufacturer’s maintenance manual contained insufficient instruction or guidance for operators and maintainers of Super King Air 200 aircraft for the lubrication of the landing gear torque tube support bearings.
Other key findings:
• Both component assemblies were integral to the function and normal operation of the Super King Air 200 mechanical landing gear system. A break down of either component assembly would have prevented any attempt by the pilot to retract or extend the aircraft’s main landing gear. However, while either failure could have produced the landing gear difficulties sustained, the investigation was not able to determine which mechanism was the principal contributor to the event.
• The investigation was unable to conclusively establish why the geared components within the right main landing gear actuator had prematurely failed.
• The lower thrust bearing within the right main landing gear actuator had been correctly installed.

Circumstances:
The aircraft departed Surgut on a flight to Belgorod with an intermediate stop in Samara, carrying 50 passengers and 7 crew members. While descending to Samara-Kurumoch Airport, weather conditions worsened and the visibility was below minimums. After the approach checklist was completed, the crew lowered the landing gear, selected flaps down at 30° and continued the approach. In poor visibility, the aircraft descended below the MDA until it struck the ground at a speed of 320 km/h and crashed 304 metres from the runway threshold and 95 metres to the left of its extended centerline. The aircraft came to rest upside down and partially burned. Six passengers were killed, 21 other occupants were injured and 30 people escaped uninjured. At the time of the accident, the visibility was estimated to be 150 metres with an RVR of 200 metres for runway 23 and a vertical visibility of 300 feet in freezing fog.
Probable cause:
The decision of the crew to continue the descent below MDA in below minimums weather conditions until the aircraft impacted ground and crashed.
The following contributing factors were identified:
- Organizational, technical and procedural deficiencies in the work and interactions between the met office and ATC services as well as from the crew,
- Deficiencies in the standards and technical documentation of the Samara Airport that made it impossible for ATC to inform the crew on a timely manner about the readings from the KRAMS-4 weather station that indicated a deterioration of the weather conditions below airport minimums,
- At decision height, in the absence of reliable visual contact with the approach lights and airport environment, the flight crew failed to initiate a go-around procedure,
- ATC failure to use the full capability of the radar equipment because of contradictions in the relevant standards and procedures documents,
- Poor crew coordination and their delay in executing a missed approach procedure,
- Lack of unified federal regulations covering flight operations, ATC, met and other services, taking into account both domestic and international experience in flight safety.
