Circumstances:
Flight MH17 departed the gate at Amsterdam-Schiphol Airport, the Netherlands at 12:13 hours local time, bound for Kuala Lumpur, Malaysia. It was airborne at 12:31 (10:31 UTC) from runway 36C and reached a cruising altitude of FL310 at 12:53 (10:53 UTC). Ninety minutes into the flight, at 12:01 UTC and just prior to entering Ukrainian airspace, the flight climbed to FL330. According to the flight plan, flight MH17 would continue at the flight level until the waypoint PEKIT, which is on the Flight Information Region (FIR) boundary between Kiev FIR (UKBV) and Dnipropetrovs’k FIR (UKDV). From waypoint PEKIT the flight plan indicates a climb to FL350 on airway L980 for the remaining part over Ukraine. According to ATC data, at 12:53 UTC the aircraft was flying within the Dnipropetrovs’k FIR, Control Sector 2, at FL330, controlled by Dnipro Control. At that time, Dnipro Control asked whether MH17 was able to climb to FL350 in accordance with the flight plan and also to clear a potential separation conflict with other traffic in the area. This traffic was Singapore Airlines flight SQ351 from Copenhagen, a Boeing 777, flying at FL330 and approaching from behind. The crew replied they were unable to comply and requested to maintain at FL330. This was agreed by Dnipro Control. As an alternative to solve the separation conflict, the other traffic climbed to FL350. According to ATC data, at 13:00 UTC the crew of flight MH17 requested to divert the track 20 NM to the left, due to weather. This also was agreed by Dnipro Control, after which the crew requested whether FL340 was available. Dnipro control informed MH17 that FL340 was not available at that moment and instructed the flight to maintain FL330 for a while. At 13:07 UTC the flight was transferred to Dnipropetrovs’k CTA 4, also with call sign Dnipro Control. At 13:19:53 UTC, radar data showed that the aircraft was 3.6 NM north of centreline of airway L980 having deviated left of track, when Dnipro Control directed the crew to alter their route directly to waypoint RND due to other traffic. The crew acknowledged at 13:19:56 hrs. At 13.20:00 hrs, Dnipro Control transmitted an onward ATC clearance to "proceed direct to TIKNA after RND", no acknowledgement was received. Data from the Flight Data Recorder and the Digital Cockpit Voice Recorder both stopped at 13:20:03 hrs. No distress messages were received from the aircraft. The airplane apparently broke up in mid-air as debris was found in a large area. The centre section of the fuselage along with parts of the horizontal and vertical stabilizers was found near Hrabove. The cockpit and lower nose section came down in a sunflower field in Rozsypne, nearly four miles (6,5 km) west-southwest of Hrabove. The L2 and R2 doors along with various parts of the fuselage were found near Petropavlivka, about 5 miles (8 km) west of Hrabove. At the point of last contact it was flying 1000 feet above airspace that had been classified as restricted by Ukrainian authorities as a result of ongoing fighting in the area. In the preceding days before the accident two Ukraine Air Force aircraft that were shot down in the region: a Su-25 and an An-26 transport plane.
Probable cause:
Causes of the crash:
a. On 17 July 2014, Malaysia Airlines operated flight MH17, an airworthy Boeing 777-200 with the registration 9M-MRD, in cruise flight near the Ukrainian/Russian border at 33,000 feet, under the control of Ukrainian Air Traffic Control and was operated by a competent and qualified crew.
b. At 13.20:03 hours (15.20:03 CET) a warhead detonated outside and above the left hand side of the cockpit of flight MH17. It was a 9N314M warhead carried on the 9M38-series of missiles as installed on the Buk surface-to-air missile system.
c. Other scenarios that could have led to the disintegration of the aeroplane were considered, analyzed and excluded based on the evidence available.
d. The impact killed the three persons in the cockpit and caused structural damage to the forward part of the aeroplane leading to an in-flight break-up. The break-up resulted in a wreckage area of 50 square km between the village of Petropavlivka and the town of Hrabove, Ukraine. All 298 occupants lost their lives.

Circumstances:
The Authority said the aircraft left the Ogle International Airport earlier in the day and made stops at Omai and Mahdia before heading at Monkey Mountain Airfield with several goods on board. On approach to Monkey Mountain, the plane circled the airstrip several times before landing. Shortly after setting down, it was claimed the aircraft veered off the runway, hit few obstacles and came to rest. While both occupants were uninjured, the aircraft was damaged beyond repair. It appears that weather was poor at the time of the accident with rain and winds and low clouds.
Probable cause:
Guyana Civil Aviation Authority (GCAA) Director General Zulficar Mohamed disclosed that an initial investigation revealed that the Pilot involved in the Monkey Mountain mishap landed short of the runway. As a result, the landing gear of the plane was damaged and from there on, it was difficult to control the 10-seater Islander aircraft. The aircraft subsequently veered off the airstrip causing extensive damage. Mr. Mohamed further stated that the wrecked aircraft is beyond repair, but he was unsure if the operators will attempt to salvage what is left. The aircraft, owned by Domestic Airways, was piloted by Captain Orlando Charles.

Circumstances:
During the takeoff roll from Coari-Urucu Airport by night, the aircraft collided with a tapir that struck the right main gear. The crew continued the takeoff procedure and the flight to Manaus. After two hours and burning fuel, the aircraft landed at Manaus-Eduardo Gomes Airport. Upon touchdown, the right main gear collapsed and the aircraft veered to the right and came to rest. All 49 occupants evacuated safely while the aircraft was damaged beyond repair.
Probable cause:
Collision with a tapir during takeoff, causing severe damages to the right main gear.
The following findings were identified:
- The lack of isolation of the operational area allowed the land animal to enter the runway for landings and takeoffs, contributing to the accident.
- The crew did not notice the presence of the land animal on the runway early enough to abort the takeoff without extrapolating the runway limits and avoiding collision.
- The presence of the land animal (Tapirus terrestris) interfered with the operation and led to the collision of the right main landing gear.

Following an uneventful flight from New Delhi-Indira Gandhi Airport, the crew was cleared for an ILS approach to Kabul Airport Runway 29. On short final, the aircraft entered an area of heavy rain falls. The crew continued the approach and the aircraft landed after the touchdown zone. Unable to stop within the remaining distance, the aircraft overran, lost its undercarriage, collided with the ILS antenna and slid for 285 metres before coming to rest. All 132 occupants evacuated safely and the aircraft was damaged beyond repair.
Probable cause:
It was determined that the crew completed the landing too far down the runway, reducing the landing distance available. The following contributing factors were identified:
- The crew failed to follow SOP's,
- Poor crew recurrent training,
- The thrust reverse systems were activated too late after landing.

Circumstances:
The aircraft took off from the Senador Nilo Coelho Aerodrome (SBPL), Petrolina - PE, to Presidente Juscelino Kubitschek International Airport (SBBR), Brasilia - DF, at 1752 (UTC), in order to complete the scheduled cargo and personnel flight O6 6393, with 5 crewmembers and 44 passengers on board. During the level flight, thirty minutes after takeoff, the aircraft presented low level in the hydraulic system 1. The crew performed the planned operational procedures and continued the flight to Brasilia, with the hydraulic system degraded. During the SBBR landing procedures, the crew used the alternative system for lowering the landing gears. The main landing gears lowered and locked, the nose landing gear unlocked, but did not lower. After coordination with the air traffic control, the aircraft was instructed to land on SBBR runway 11R. The landing took place at 2042 (UTC). After the touchdown, the aircraft covered a total distance of 900 meters until its full stop. The initial 750 meters were with the aircraft supported only by the main landing gears and the last 150 meters were with the aircraft supported by the main landing gears and by the lower part of the front fuselage. The aircraft stopped on the runway. Substantial damage to structural elements of the aircraft occurred near the nose section. The evacuation of the crewmembers and passengers was safe and orderly. The copilot suffered fractures in the thoracic spine. The other crewmembers and passengers left unharmed.
Probable cause:
The following findings were identified:
- It was found that there was a restriction on the articulation movement of the right nose landing gear door and that the weight of this landing gear was not sufficient to overcome such restriction.
Upon inspecting the hinges, it was found that there were no signs of recent lubrication, allowing the hypothesis of occurrence of any deviation or non-adherence to the inspection and lubrication requirements established by the manufacturer leading to a the scenario favorable to the right door movement restriction. The issue of the maintenance could also be related to some deviation, or nonadherence to the requirements established for the service of widening the holes of the hinges concerning the coating and corrosion protection of the worked surface. As a result, the area could have been more susceptible to corrosive processes.
- The maintenance program, established by the manufacturer, may have contributed to the occurrence by not establishing adequate preventive maintenance parameters for the landing gear doors that were modified by reworking the hinges, incorporating larger radial pins and widening the lobe holes.
- It was not possible to determine the causal root of the EDP1 gasket extrusion, which caused the leakage of hydraulic oil that caused the hydraulic system 1 to fail.

Circumstances:
Before pushback from the gate, the first officer, who was the pilot monitoring, initialized the flight management computer (FMC) and mistakenly entered the incorrect departure runway (27R instead of the assigned 27L). As the captain taxied onto runway 27L for departure, he noticed that the wrong runway was entered in the FMC. The captain asked the first officer to correct the runway entry in the FMC, which she completed about 27 seconds before the beginning of the takeoff roll; however, she did not enter the FLEX temperature (a reduced takeoff thrust setting) for the newly entered runway or upload the related V-speeds. As a result, the FMC's ability to execute a FLEX power takeoff was invalidated, and V-speeds did not appear on the primary flight display (PFD) or the multipurpose control display unit during the takeoff roll. According to the captain, once the airplane was cleared for takeoff on runway 27L, he set FLEX thrust with the thrust levers, and he felt that the performance and acceleration of the airplane on the takeoff roll was normal. About 2 seconds later, as the airplane reached about 56 knots indicated airspeed (KIAS), cockpit voice recorder (CVR) data indicate that the flight crew received a single level two caution chime and an electronic centralized aircraft monitoring (ECAM) message indicating that the thrust was not set correctly. The first officer called "engine thrust levers not set." According to the operator's pilot handbook, in response to an "engine thrust levers not set" ECAM message, the thrust levers should be moved to the takeoff/go-around (TO/GA) detent. However, the captain responded by saying "they're set" and moving the thrust levers from the FLEX position to the CL (climb) detent then back to the FLEX position. As the airplane continued to accelerate, the first officer did not make a callout at 80 KIAS, as required by the operator's standard operating procedures (SOPs). As the airplane reached 86 KIAS, the automated RETARD aural alert sounded and continued until the end of the CVR recording. According to Airbus, the RETARD alert is designed to occur at 20 ft radio altitude on landing and advise the pilot to reduce the thrust levers to idle. The captain later reported that he had never heard an aural RETARD alert on takeoff, only knew of it on landing, and did not know what it was telling him. He further said that when the RETARD aural alert sounded, he did not plan to reject the takeoff because they were in a high-speed regime, they had no red warning lights, and there was nothing to suggest that the takeoff should be rejected. The first officer later reported that there were no V-speeds depicted on the PFD and, thus, she could not call V1 or VR during the takeoff. She was not aware of any guidance or procedure that recommended rejecting or continuing a takeoff when there were no V-speeds displayed. She further said she "assumed [the captain] wouldn't continue to takeoff if he did not know the V-speeds." The captain stated that he had recalled the V-speeds as previously briefed from the Taxi checklist, which happened to be the same V-speeds for runway 27L. The captain continued the takeoff roll despite the lack of displayed V-speeds, no callouts from the first officer, and the continued and repeated RETARD aural alert. FDR data show that the airplane rotated at 164 KIAS. However, in a postaccident interview, the captain stated that he "had the perception the aircraft was unsafe to fly" and that he decided "the safest action was not to continue," so he commenced a rejected takeoff. FDR data indicate that the captain reduced the engines to idle and made an airplane-nose-down input as the airplane reached 167 KIAS (well above the V1 speed of 157 KIAS) and achieved a 6.7 degree nose-high attitude. The airplane's pitch decreased until the nose gear contacted the runway. However, the airplane then bounced back into the air and achieved a radio altitude of about 15 ft. Video from airport security cameras show the airplane fully above the runway surface after the bounce. The tail of the airplane then struck the runway surface, followed by the main landing gear then the nose landing gear, resulting in its fracture. The airplane slid to its final resting position on the left side of runway 27L. The operator's SOPs address the conditions under which a rejected takeoff should be performed within both low-speed (below 80 KIAS) and high-speed (between 80 KIAS and V1) regimes but provide no guidance for rejecting a takeoff after V1 and rotation. Simulator testing performed after the accident demonstrated that increasing the thrust levers to the TO/GA detent, as required by SOPs upon the activation of the "thrust not set" ECAM message, would have silenced the RETARD aural alert. At the time of the accident, neither the operator's training program nor manuals provided to flight crews specifically addressed what to do in the event the RETARD alert occurred during takeoff; although, 9 months before the accident, US Airways published a safety article regarding the conditions under which the alert would activate during takeoff. The operator's postaccident actions include a policy change (published via bulletin) to its pilot handbook specifying that moving the thrust levers to the TO/GA detent will cancel the RETARD aural alert. Although simulator testing indicated that the airplane was capable of sustaining flight after liftoff, it is likely that the cascading alerts (the ECAM message and the RETARD alert) and the lack of V-speed callouts eventually led the captain to have a heightened concern for the airplane's state as rotation occurred. FDR data indicate that the captain made erratic pitch inputs after the initial rotation, leading to the nose impacting the runway and the airplane bouncing into the air after the throttle levers had been returned to idle. Airbus simulation of the accident airplane's acceleration, rotation, and pitch response to the cyclic longitudinal inputs demonstrated that the airplane was responding as expected to the control inputs. Collectively, the events before rotation (the incorrect runway programmed in the FMC, the "thrust not set" ECAM message during the takeoff roll, the RETARD alert, and the lack of required V-speeds callouts) should have prompted the flight crew not to proceed with the takeoff roll. The flight crewmembers exhibited a self-induced pressure to continue the takeoff rather than taking the time to ensure the airplane was properly configured. Further, the captain initiated a rejected takeoff after the airplane's speed was beyond V1 and the nosewheel was off the runway when he should have been committed to the takeoff. The flight crewmembers' performance was indicative of poor crew resource management in that they failed to assess their situation when an error was discovered, to request a delayed takeoff, to communicate effectively, and to follow SOPs. Specifically, the captain's decision to abort the takeoff after rotation, the flight crew's failure to verify the correct departure runway before gate departure, and the captain's failure to move the thrust levers to the TO/GA detent in response to the ECAM message were all contrary to the operator's SOPs. Member Weener filed a statement, concurring in part and dissenting in part, that can be found in the public docket for this accident. Chairman Hart, Vice Chairman Dinh-Zarr, and Member Sumwalt joined the statement.
Probable cause:
The captain's decision to reject the takeoff after the airplane had rotated. Contributing to the accident was the flight crew's failure to follow standard operating procedures by not verifying that the airplane's flight management computer was properly configured for takeoff and the captain's failure to perform the correct action in response to the electronic centralized aircraft monitoring alert.

Circumstances:
The Boeing 777-2H6ER took off from Kuala Lumpur Airport runway 32R at 0041LT bound for Beijing. Some 40 minutes later, while reaching FL350 over the Gulf of Thailand, radar contact was lost. At this time, the position of the aircraft was estimated 90 NM northeast of Kota Bharu, some 2 km from the IGARI waypoint. More than 4 days after the 'accident', no trace of the aircraft has been found. On the fifth day of operation, several countries were involved in the SAR operations, in the Gulf of Thailand, west of China Sea and on the Malacca Strait as well. All operations are performed in coordination with China, Thailand, Vietnam, Malaysia and Philippines. No distress call or any kind of message was sent by the crew. The last ACARS message was received at 0107LT and did not contain any error, failure or technical problems. At 0119LT was recorded the last radio transmission with the crew saying "All right, good night". At 0121LT, the transponder was switched off and the last radar contact was recorded at 0130LT. Several hypothesis are open and no trace of the aircraft nor the occupant have been found up to March 18, 2014. It is now understood the aircraft may flew several hours after it disappeared from radar screens, flying on an opposite direction from the prescribed flight plan, most probably to the south over the Indian Ocean. No such situation was ever noted by the B3A, so it is now capital to find both CVR & DFDR to explain the exact circumstances of this tragic event. Considering the actual situation, all scenarios are possible and all hypothesis are still open. On Mar 24, 2014, the Malaysian Prime Minister announced that according to new computations by the British AAIB based on new satellite data, there is no reasonable doubt that flight MH370 ended in the South Indian Ocean some 2,600 km west of Perth. Given the situation, the Malaysian Authorities believe that there is no chance to find any survivors among the 239 occupants.

***************************

According to the testimony of 6 Swiss Citizens making a cruise between Perth and Singapore via Jakarta, the following evidences were spotted on March 12 while approaching the Sunda Strait:
1430LT - latitude 6° S, longitude 105° E, speed 17,7 knots:
life jacket, food trays, papers, pieces of polystyrene, wallets,
1500LT:
a huge white piece of 6 meters long to 2,5 meters wide with other debris,
1530LT:
two masts one meter long with small flags on top, red and blue,
2030LT - latitude 5° S, longitude 107° E, speed 20,2 knots.

This testimony was submitted by these 6 Swiss Citizens to the Chinese and Australian Authorities.

On April 21, 2016, it was confirmed that this testimony was recorded by the Swiss Police and transmitted to the Swiss Transportation Safety Investigation Board (STSB), the State authority of the Swiss Confederation which has a mandate to investigate accidents and dangerous incidents involving trains, aircraft, inland navigation ships, and seagoing vessels. The link to the STSB is http://www.sust.admin.ch/en/index.html.

***************************

On July 29, 2015, a flaperon was found on a beach of the French Island of La Réunion, in the Indian Ocean. It was quickly confirmed by the French Authorities (BEA) that the debris was part of the Malaysian B777. Other debris have been found since, in Mozambique and South Africa.

On May 12, 2016, Australia's TSB reported that the part has been identified to be a "the decorative laminate as an interior panel from the main cabin. The location of a piano hinge on the part surface was consistent with a work-table support leg, utilised on the exterior of the MAB Door R1 (forward, right hand) closet panel". The ATSB reported that they were not able to identify any feature on the debris unique to MH-370, however, there is no record that such a laminate is being used by any other Boeing 777 customer.

***************************

On September 15, 2016, the experts from the Australian Transportation Safety Bureau (ATSB) have completed their examination of the large piece of debris discovered on the island of Pemba, off the coast of Tanzania, on June 20, 2016. Based on thorough examination and analysis, ATSB with the concurrence of the MH370 Safety Investigation Team have identified the following:
- Several part numbers, along with physical appearance, dimensions, and construction confirmed the piece to be an inboard section of a Boeing 777 outboard flap.
- A date stamp associated with one of the part numbers indicated manufacture on January 23, 2002, which was consistent with the May 31, 2002 delivery date for MH370,
- In addition to the Boeing part number, all identification stamps had a second 'OL' number that were unique identifiers relating to part construction,
- The Italian part manufacturer has confirmed that all numbers located on the said part relates to the same serial number outboard flap that was shipped to Boeing as line number 404,
- The manufacturer also confirmed that aircraft line number 404 was delivered to Malaysian Airlines and registered as 9M-MRO (MH370)

As such, the experts have concluded that the debris, an outboard flap originated from the aircraft 9M-MRO, also known as flight MH370. Further examination of the debris will continue, in hopes that further evidence may be uncovered which may provide new insight into the circumstances surrounding flight MH370.
Probable cause:
Due to lack of evidences the exact cause of the accident could not be determined.
