Circumstances:
The crew took off from Leipzig Airport at 0438LT bound for Bratislava Airport (Slovakia). The approximately forty-five minutes flight took place without incident and the crew was cleared for the ILS approach to runway 22. The Captain was PF. During the descent, the controller informed the crew that the wind was from  120° at  7  kt. The crew selected the slats and flaps at 25°. The antiskid and the autobrake were armed in MED mode. The ILS 22 approach was stable until the wheels touched down. The main landing gear touched the runway about 700 m from the threshold of runway  22. The crew deployed the thrust reversers. About six seconds after the nose gear touched, the crew felt strong vibrations that increased as the speed dropped. At 85 kt, the thrust reversers were retracted. The aeroplane veered towards the left. The PF explained that he applied energetic braking and tried in vain to counter the rocking by using the rudder pedals then the nose gear steering control. He  added that the sequence occurred so quickly that he did not think to use differential braking to try to keep the aeroplane on the runway. The aeroplane exited the runway to the left at a speed of about 45 kt. Its nose gear struck a concrete inspection pit and collapsed. The aeroplane skidded for a few dozen metres before coming to a stop. The crew evacuated the aeroplane. Between the start of the vibrations and the aeroplane stopping, it had rolled about 400 metres.
Probable cause:
Incorrect installation of one or more washers on the nose gear torque link centre hinge made it impossible to lock the hinge shaft nut effectively. The unscrewing and the detachment of the latter in service caused the loss of nose gear steering. Free on its axle, the nose gear bogie began to shimmy, which made the aeroplane veer to the left. The aeroplane exited the runway and the nose gear collapsed during the collision with a concrete inspection pit for access to the runway lighting electric cables.The runway excursion was due to the incorrect and undetected re-assembly of the nose gear torque links. Despite the presence of a detailed diagram, the absence of clear and detailed instructions in the text of the manufacturer’s AMM, allowing the operator to ensure that the assembly was correct, contributed to the incorrect assembly. The failure of the nose gear was due to the collision with an obstacle in the runway  strip. The absence of any regulation requiring that equipment in the immediate vicinity of a runway or of a runway overrun area be designed so as to limit as much as possible any damage to aeroplanes, in case of a runway excursion, contributed to the accident.

Circumstances:
The aircraft was substantially damaged when it collided with a hedgerow during a forced landing following a loss of engine power near Wichita, Kansas. The loss of engine power occurred about 4-1/2 minutes after departing Wichita Mid-Continent Airport (ICT), Wichita, Kansas. The commercial pilot, who was the sole occupant, was fatally injured. The airplane was registered to the Federal Express Corporation and operated by Baron Aviation Services Incorporated, under the provisions of 14 Code of Federal Regulations Part 135 while on an instrument flight plan. Day visual meteorological conditions prevailed for the cargo flight that had the intended destination of Garden City Regional Airport (GCK), Garden City, Kansas. According to air traffic control transmissions, at 0734:35 (hhmm:ss), the pilot requested an instrument flight rules clearance from ICT to GCK. Radar track data indicated that the airplane departed runway 19R approximately 0737:45. At 0738:18, the tower controller told the pilot to change to the departure control frequency. The departure controller then cleared the flight to proceed direct to GCK and to climb to 8,000 ft mean sea level (msl). The airplane continued to climb on a westerly heading until 0742:02, at which time the airplane began a left 180-degree turn back toward the departure airport. According to radar data, the airplane had reached 4,700 ft msl when it began the left turn. At 0742:13, the pilot transmitted that his airplane had experienced a loss of engine power and that he was attempting to return to the departure airport. At 0742:31, the pilot asked if there were any nearby airports because he was unable to reach ICT. The departure controller provided vectors toward an airstrip that was approximately 2.5 miles southeast of the airplane's position. At 0743:46, the pilot advised that he could not see the airstrip because the airplane's windshield was contaminated with oil. At 0744:57, the pilot's final transmission was that he was landing in a grass field. The airplane was located about 2.2 miles south of ICT at 1,600 feet msl, about 300 feet above ground level (agl) at the time of the last transmission. The radar data continued northeast another 1/2 mile before radar contact was lost at 0745:15. A witness to the accident reported that he was outside his residence when he observed the accident airplane overfly his position. He recalled that the airplane's propeller was not rotating and that he did not hear the sound of the engine operating. He stated that the airplane landed in a nearby agricultural field on a northeast heading. He reported that during the landing rollout the airplane impacted a hedgerow located at the northern edge of the field. The witness indicated that the pilot was unresponsive when he arrived at the accident site and that there was a small grass fire located 8 to 10 feet in front of the main wreckage.
Probable cause:
The total loss of engine power as a result of a fractured compressor turbine blade due to high-cycle fatigue.

Circumstances:
The airplane was destroyed when it collided with tree-covered terrain and incurred a postcrash fire and explosion about 19 miles west of Willow, Alaska. The airline transport rated
pilot, who was the only occupant, was fatally injured. The airplane was registered to Fuel Services, LLC, Anchorage, Alaska, and was being operated as a 14 CFR Part 91 visual flight rules (VFR) cross-country fuel transport flight when the accident occurred. Marginal visual meteorological conditions were reported at the airplane's point of departure. The accident flight originated from the Wasilla Airport, Wasilla, Alaska, about 1520, en route to the Nixon Fork Mine, about 28 miles northeast of McGrath, Alaska. According to the co-owner of the airplane, the purpose of the flight was to transport approximately 900 gallons of diesel fuel to a company owned tank that supplies fuel for a mining operation. When the airplane did not arrive at its destination, the co-owner of the airplane reported it overdue to the Federal Aviation Administration (FAA) at 1757. After being notified of the overdue airplane, personnel from the 11th Air Force's Rescue Coordination Center initiated a search for the missing airplane along its supposed route of flight. On the morning of October 16, an Air National Guard C-130 Hercules was able to locate the wreckage. Rescue personnel aboard a HH-60G helicopter were able to reach the site later that morning, and confirmed the pilot was deceased. Two witnesses reported seeing the airplane fly over their locations. The first witness saw the airplane as it was flying northwest at an altitude that he estimated at 3,000 to 4,000 feet under an overcast layer. He stated that the airplane did not sound "normal," but he did not notice anything unusual, like smoke, trailing the airplane. The second witness stated that he saw the airplane fly over his cabin headed southeast at an estimated altitude of 300 to 400 feet. He stated that the airplane sounded like it was "struggling," but he could not see anything abnormal about the airplanes appearance. Primary radar data taken from the Anchorage Terminal Radar Approach Control Facility (TRACON), shows an unidentified aircraft, believed to be the accident airplane, depart the Wasilla airport about 1522. After departure, the track proceeded to the Northwest with cruising ground speeds of between 180 and 193 knots. No altitude or transponder code data was transmitted by the airplane. Around 1343 the radar track changed direction and proceeded to the southeast. Ground speeds after the track changed direction started at 143 knots, and gradually decreased to a low of 117 knots about 5 minutes before the accident. The last radar plot for the airplane was at 1556:47, approximately 5.5 nautical miles from the accident site, and showed a heading of 088 degrees, and a ground speed of 175 knots.
Probable cause:
The pilot’s loss of control of the airplane for reasons that could not be determined because the wreckage was not recovered from the accident site.

Circumstances:
The airplane took off from Miami International Airport (KMIA), destined for Viracopos Airport (SBKP), with two pilots and a mechanic on board, on a non-regular cargo transport flight. The flight was uneventful up to the moment its landing in SBKP. On the approach for landing on runway 15, the crew performed the IFR ILS Z procedure. The weather conditions were VMC, with the wind coming from 140º at 19kt. When the aircraft was granted clearance to land, the wind strength was 20kt, gusting up to 29kt. The copilot was the Pilot Flying (PF), and the captain was the Pilot Monitoring (PM) at the moment of landing. When the aircraft touched down on the runway after the flare, the left main landing gear collapsed, causing the aircraft to skid on the runway for approximately 800 meters before stopping. There was substantial damage to the left main gear assembly, to the left wing, and left engine. The aircraft stopped within the runway limits. All three crew members were uninjured.
Probable cause:
It was determined that the “the landing gear failed due to overload in the cylinder structure”. The fracture started in the rear section of the cylinder in a connection hole which served as a tension concentration point, and ended in the front part of the cylinder with its breakage into two parts. Following a failure of the right main gear upon landing in Montevideo on 20 October 2009, the right main landing gear was replaced by VARIG Engineering & Maintenance (VEM), but the organization responsible for the research of damage, the specification of the services necessary for the restoration of airworthiness, and the provision of the services that enabled the restoration of the aircraft to an airworthy condition was not identified. The same aircraft parts were subjected to metallurgical analysis at the Boeing Long Beach Materials, Processing and Physics [MP&P] Laboratories, in Huntington Beach, California, USA; and the technical report issued by Boeing highlighted that in one of the points of origin of the failure, the analysis had identified characteristics similar to a pre-crack point, which would have begun earlier, probably due to overload. In the tasks that led to the restoration of the aircraft airworthiness after the accident in Uruguay in 2009 (Hard-Landing), and also in subsequent periodic inspections, the existence of pre-crack traces resulting from a previous overload condition may not have been identified, something that could have resulted in a point of stress concentration.

Circumstances:
On 03 October 2012, a Pacific Aerospace LTD, PAC 750 XL aircraft registration PK-RWT was being operated by Yayasan Pelayan Penerbangan Tariku on a cargo supply flight from Koropun to Dekai in Papua area. This flight was the 9 th flight of that day. All flights were performed in accordance to the Visual Flight Rules (VFR). The first flight was from Sentani to Langda which was arrived at 2220 UTC (0720 LT). The aircraft arrived Koropun at 0120 UTC (1020 LT) as reported by the pilot through the company flight following system . The aircraft then departed Koropun to Dekai and lost contact during this flight. On board in this flight were one pilot, one passenger and 975 kg of cargo when departure from Sentani. The distance between Koropun to Dekai is about 24.6 Nm and normally takes about 11 minutes. The weather information issued by Badan Meteorologi Klimatologi and Geofisika/BMKG (Indonesia Meteorology Climatology and Geophysics Agency) between 0200 UTC to 0300 UTC, showed the development of cumulus cloud classified as Middle Cloud formation along the route from Koropun to Dekai. According to the company flight following procedure, the pilot should report after the aircraft lands by mentions “aircraft on the ground” which this means that the aircraft had arrived at destination. After aircraft airborne, the pilot should report aircraft airborne time and give the estimate of time arrival at destination. The last contact of the pilot was “the aircraft on the ground Koropun” at 0120 UTC. Normally, the next report would be within 15 up to 20 minutes after arrival. There was no report from the pilot after 20 minutes of the last report. The flight following officer tried to contact the pilot and was unsuccessful. At 0145 UTC, the Operation Manager of the aircraft operator received information from the New Zealand Search and Rescue Agency that informed that Local User Terminal (LUT) has received ELT distress signal from PK-RWT. This information was followed by information through email, which was received at 0150 UTC. Based on this information, the Indonesia Search and Rescue operation was initiated. The aircraft was found on 5 October 2013, in mountainous area with approximate elevation of 7,000 feet, at coordinate 04°28.62’S 139°39’E. The crew and passenger on board were fatally injured and the aircraft substantially damaged.
Probable cause:
The accident was classified as Controlled Flight into Terrain (CFIT), which most likely the aircraft was flown into the weather environment below the VFR margins.

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:
On 2nd June, 2012 at 1828hrs Allied Air Ltd Flight DHV 111, a Boeing 727-221 Cargo aircraft, Registration: 5N-BJN, departed Murtala Muhammed International Airport, Ikeja, Lagos-Nigeria to Kotoka International Airport, estimating Accra, Ghana at 1904hrs, en-route to Abidjan. While taxiing for take-off, the Flight Engineer observed that the CSD amber light (caution) had illuminated on the panel. With the Captain’s permission, it was disconnected. The flight was cleared Flight Level 240 and to maintain by Accra Area Control on 130.9MHz. The Flight was operating under Instrument Flight Rules (IFR) conditions and the flight was turbulent, the aircraft was cruising at a speed of 280kts which is the recommended turbulence speed. On the descent into Accra, the aircraft was cleared by Accra Approach on 119.5MHz initially to Flight Level 50 and later cleared to 2000ft. It was again instructed to climb to 3000ft due to high ground. On arrival at Accra, the Captain flew an Instrument Landing System (ILS) coupled approach, until he saw the runway. He then disconnected the autopilot at 500ft and manually flew the aircraft. After disconnecting the auto-pilot, he came into heavy IMC conditions in rain. The aircraft experienced an unstable approach at a high speed of 167kts and landed with a wind of 050/15kts at 154 kts and about 5807 ft from Runway 21 in nil visibility. The crew deployed thrust reversers and applied the normal brakes as well as the emergency pneumatic brakes but these actions were ineffective to stop the aircraft. Normally deploying the thrust reversers or applying the brakes would bring the nose wheel down. However, the nose gear was kept up. The speed brakes were not deployed. The crew reported seeing red lights rushing towards them soon after the main wheels touched the ground for the landing run. The aircraft nose gear never touched the ground until the aircraft went over the fence wall. A Lufthansa Flight DLH 566 operated on behalf of Lufthansa (LH) by Private Air which had landed earlier at 1902hrs reported a wind of 050/15kts and visibility of 3800m in rain. From the 2nd intersection where DLH 566 had stopped, ready to backtrack Runway 21, the crew observed Allied Air appeared to have landed at very high speed when the aircraft went past and could not determine whether the aircraft was taking off. A Lufthansa ground engineer who was waiting at the intersection to receive DLH 566 indicated the approximate touchdown point of DHV 111. Both the controller at the Tower and the Marshaller in the “follow me” vehicle waiting at the 1st Intersection saw Allied Air land between the 1st and 2nd intersections. The FDR indicated that the aircraft landed 4000 ft to the end of Runway 21. The full length of Runway 21 is 3403 m (11,162ft for take-off) but available for landing is 2990 m (9,807 ft). The FDR readout showed that the aircraft landed at 150 kts, and at 1.6 G, 5807 ft from the beginning of Runway 21 and 4000ft from the threshold of the Runway 03. The runway surface condition for braking as described by DLH crew was good. Shortly after Turkish Airline (THY 629) had landed, DLH 566 also landed followed by DHV 111. The aircraft over-run the runway and destroyed the Threshold Lights and the Approach lights on Runway 03. It knocked out the ILS Localizer transmitter structure and mounts, broke through the airport perimeter wall. The aircraft crossed Giffard Road, collided with a passenger mini bus killing all ten (10) persons on board. It uprooted a tree by the road side before finally coming to a stop at an open space near El-Wak Sport Stadium. The Emergency Locator Transmitter (ELT) was triggered by the impact. The right side of a taxi cab on the road was grazed by flying debris from the localizer transmitter structures carried along by the right wing of the aircraft. The leading edge of the wing was extensively damaged. The aircraft came to a rest outside the airport perimeter wall 1171 ft (350m) from the Threshold of Runway 03, heading 215° southwest, coordinates 05 35 13.67N 000o 10 29.20W. The four (4) crew members sustained minor injuries. The aircraft and the mini bus were all destroyed. At 1910hrs, RFFS was alerted by the Tower Controller through the crash alarm bell. It took 9 minutes for the firemen to get to the crash site. The Airport was closed for 45minutes during which runway inspection was carried out. No pool of water was found anywhere on the runway. Approximately one hour after the aircraft had over-run the runway, the Airport was re-opened to traffic. Other airlines including KLM and British Airways, landed. Even though the Technical Log Book had no records of deferred defect, the Captain in an interview said the windshield wipers where switched on during the landing phase but were unable to clear the rain. It was observed during the investigation that the windshield wipers were rather ¾ switched on.
Probable cause:
The probable causes of the accident were:
The decision of the Captain to continue with the landing instead of aborting at the missed approach point especially when he could hardly see through the windshield and when he did not know how far he had gone down the runway because of the rain and the tail wind components.
Contributory factors:
a. The Captain disconnected the auto-pilot and flew the aircraft manually in an unstable approach.
b. The Captain landed the aircraft at 4000ft to the threshold of Runway 03, 6060ft from Runway 21. He could not stop within the available distance.
c. The Captain chose to land with a tailwind of 050/15Kts in excess of maximum allowable tailwind of 10Kts.
d. The crew concentrated on tracking the Localizer rather than watching for threshold and runway edge lights. They suffered from fixation.
e. The Captain did not deploy speed brakes on landing.
Final Report:
