Captain / Total flying hours:

Circumstances:
The aircraft departed Den Helder-De Kooy Airport on a radar tracking flight over the North Sea. Following an uneventful mission, the crew was returning to De Kooy Airport. After touchdown on runway 03, the crew activated the thrust reverser systems when the aircraft lost controllability. The pilot attempted to maintain control and selected the left throttle from 'reverse' again to turn to the right. Eventually, he feathered the right propeller and cut off the fuel supply, causing the right engine to stop. The aircraft veered off runway to the left and came to rest in a ditch. Both pilots escaped uninjured and the aircraft was damaged beyond repair.
Probable cause:
The landing speed, the touchdown point, the runway length and runway condition were considered as good. The problem was the consequence of an expired adjustment screw of the speed controller ('prop governor') on the right engine, so that it did not come into 'reverse pitch' but continued to provide forward thrust, causing an asymmetric aerodynamic braking effect. It was also determined that the Beta light indicator burned and could not light on, preventing the pilot from a possible issue on the reverse thrust system.

Circumstances:
After takeoff from Chania-Souda Airport, the crew reported technical problems with the right main gear that could not be raised properly in its wheel well. The captain decided to continue to Munich in a gear down configuration but the fuel consumption increased. En route, the crew realized he could not make it to Munich so diverted to Vienna-Schwechat Airport. At a distance of about 12 NM from the airport, at an altitude of 4,000 feet, both engines failed due to fuel exhaustion. One of the engine could be restarted for a short period of time but on short final, the aircraft stalled and struck the ground (a grassy area) about 500 metres short of runway 34. The left main gear broke off, the aircraft slid for some 600 metres then veered to the left and came to rest on its left wing. All 151 occupants were rescued, among them 26 passengers were slightly injured. The aircraft was damaged beyond repair.
Probable cause:
Continuation of the flight with a landing gear problem until the engines failed due to fuel exhaustion.
The following findings were identified:
Crew:
- Failure to comply with the company's rules on fuel reserves, caused by several human factors, with extreme workload and stress being the important factor (loss of situational awareness).
- Determination of the fuel reserves using only the FMS, which, due to its characteristics did not take into account the additional fuel consumption.
- Failure to develop alternative strategies to curb the fuel problem.
- Failure to comply with a fuel warning (low fuel level warning) and decision to continue the flight to Vienna International Airport, although the plane was in the immediate vicinity of Zagreb Airport.
Manufacturer:
- Inadequate and misleading documentation (FMS scheme, altitude, terms) for this specific case, particularly in relation to the restriction of FMS.
Operator:
- Inadequate documentation for "abnormal landing gear up indication" of the abnormal checklist.
- Lack of review of the fuel needs by the Operations Division.
Contributing factors:
- Missing or inadequate preventive measures by manufacturers, approving authority and airlines following the previous publications of ICAO and EU DG VII about problems which, with the introduction of aircraft equipped with modern technologies, occurred and had been identified.
- Anthropo-technical construction deficiencies, which favour a misinterpretation of the FMS EFOB display.

Circumstances:
The aircraft, registered to a private individual, departed Villavicencio-La Vanguardia Airport on a charter flight to Mitú, carrying 17 passengers and two pilots while the aircraft was certified to carry 13 passengers maximum. The crew filed an flight plan with only six people on board. Shortly after takeoff, while in initial climb, the right engine caught fire. The crew activated the fire extinguishing system but as both bottles were empty, the fire could not be contained. The captain initiated a right hand turn to return to the airport when the aircraft stalled and crashed, bursting into flames, two minutes after takeoff. Both pilots and eight passengers were killed while nine other people were injured. The aircraft was totally destroyed by impact forces and a post crash fire.
Probable cause:
The decision and inappropriate operation of the pilot to return with a right hand turn with an uncontrolled fire in the n°2 engine leading to a loss of lift on the wing on that side and a loss of control over the aircraft. It was also determined that the aircraft was not airworthy at the time of the accident. The crew flying experience could not be determined as the crew failed to complete their personal logbook. Also, the captain's medical certificate was not valid anymore.

Circumstances:
Originally, flight MA262 from Budapest to Thessaloniki should be performed by a Boeing 737-300 HA-LES but due to technical problems, a Tupolev TU-154B-2 was dispatched. Following an uneventful flight, the crew was cleared for a VOR/DME approach to runway 34 followed by a visual circle to land on runway 28 as the runway 34 was closed to traffic due to construction works. Because a Boeing 757 slowed to vacate the runway after landing, ATC instructed the crew to extend the downwind leg for runway 28. For unknown reasons, the crew failed to comply with this instructions and performed 'S'. On final approach, the tower controller informed the crew that he forgot to lower the undercarriage. The captain increased engine power and initiated a go-around procedure but this decision was too late. The aircraft continued to descend and struck the runway surface in a gear-up configuration at 1657LT. The aircraft suffered substantial damages but the crew managed to go-around and to follow a holding pattern. A safe landing was completed at 1715LT. All 94 occupants evacuated safely while the aircraft was damaged beyond repair.
Probable cause:
Despite repeated instructions of the control tower the crew did not carried out a short turn for landing, resulting in:
- The aircraft was not aligned with the runway in time (unstabilized approach).
- Attention of the cockpit crew was to exclusively dedicated to performing sudden maneuvers at low altitude, in order to align the plane with the runway.
- Failure to lower the undercarriage in accordance with the applicable procedures for this flight phase.
Contributing Factors:
- The apparent inactivation of the audible warning when the undercarriage was not deployed.
- Lack of Cockpit Resources Management.

Circumstances:
The Beechcraft Queen Air and Rockwell Aero Commander were being used by a company to conduct private category passenger-carrying flights to transport its workers from Leonora to Laverton in Western Australia. The Aero Commander had departed and was established in the Leonora circuit area when the Queen Air took off. The pilot and one of the passengers of the Queen Air reported the take-off roll appeared normal until the aircraft crossed the runway intersection, when they felt a bump in the aircraft. The pilot reported hearing a loud bang and noticed that the inboard cowl of the right engine had opened. He also reported that he believed he had insufficient runway remaining to stop safely, so he continued the takeoff. The cowl separated from the aircraft at the time, or just after the pilot rotated the aircraft to the take-off attitude. He reported that although the aircraft had left the ground after the rotation, it then would not climb. The aircraft remained at almost treetop level until the pilot and front-seat passenger noticed the side of a tailings dump immediately in front of the aircraft. The pilot said that he pulled the control column fully back. The aircraft hit the hillside parallel to the slope of the embankment, with little forward speed. The impact destroyed the aircraft. Although the occupants sustained serious injuries, they evacuated the aircraft without external assistance. There was no post-impact fire. The aircraft-mounted emergency locator transmitter (ELT) did not activate.
Probable cause:
The examination of the Queen Air wreckage found no mechanical fault that may have contributed to the accident sequence other than the inboard cowl of the right engine detaching during the takeoff. The cowl latching mechanisms appeared to have been capable of operating normally. The two top hinges failing in overload associated with the lack of cowl latch damage suggested that the cowl was probably improperly secured before takeoff. The cowl appeared to have subsequently opened when it experienced the jolt when the aircraft crossed the runway intersection. The lack of any further cowl damage indicated that it detached cleanly and consequently its dislodgment should not have adversely affected the flying qualities of the aircraft.

Circumstances:
The aircraft departed Makhachkala on a flight to Khabarovsk with intermediate stops at Privolzhskiy AFB and Vozzhayevka AFB, carrying 221 passengers and a crew of seven on behalf of the Russian Ministry of Defense. Some 23 minutes after takeoff from Privolzhskiy AFB, while cruising at an altitude of 6,100 metres, the crew encountered technical problems with the fuel system and was cleared to return for an emergency landing. While descending to Privolzhskiy AFB, the flaps could not be lowered and a fire erupted in the left wing. After touchdown, the aircraft was unable to stop within the remaining distance, overran, lost its undercarriage and came to rest 200 metres further, bursting into flames. All 232 occupants evacuated safely while the aircraft was destroyed by a post crash fire.
Probable cause:
An in-flight fire occurred in the area between the second and third flap tracks on the left wing, which led to a failure of the fuel lines, hydraulic systems and flap control systems. The most likely cause of the fire was a production flaw, causing electric wires to touch the hydraulic system pipeline, which led to a chafing of the insulation of the wires, their short circuit with subsequent piercing of the pipeline and ignition. The unsuitability of fire extinguishing means and the unpreparedness of the fire brigade of the Privolzhskiy AFB to extinguish fires on aircraft with a flight mass of more than 50 tons led to the destruction by fire of the aircraft on the ground.
