On 17 February 2014, a 748 Air Services Hawker Siddeley HS 748 performing a humanitarian cargo flight from Juba International Airport to Bentiu Airport, South Sudan crash-landed at Bentiu, killing one of four occupants.


Incident

The flight was operating an humanitarian aid cargo flight from Juba to Bentiu during the South Sudanese conflict. The aircraft was on approach to land at Bentiu Airport when it crash-landed. The plane touched down too fast, causing it to veer off the runway, run across a ditch and strike two parked vehicles. As a result, the aircraft broke up and shortly afterwards caught fire. One crew member died and three others on board were injured. This was the first commercial aviation accident in South Sudan since the country became independent in 2011. A witness on the ground reported that the aircraft was attempting an unstabilized approach at high speed. The crash resulted in hull loss.

On 20 January 2014, a Britten-Norman Islander light aircraft belonging to the Superior School of Aviation in Romania (Romanian: Școala Superioară de Aviație Civilă) crashed in the Apuseni Mountains at an altitude of approximately 1,400 metres (4,600 ft), near the village of Petreasa, between Alba and Cluj counties. The aircraft was piloted by two crew and was transporting a five-person medical team from Bucharest to Oradea. The pilot and a medical student died, while the copilot and four medical doctors were injured.


Accident

The aircraft, property of the Superior School of Civil Aviation in Romania, took off at 13:35 from Aurel Vlaicu International Airport in Bucharest and was bound for Oradea International Airport, where it should have landed at 16:35. The flight was a humanitarian mission and was crewed by a 55-year-old with 16,000 hours flying experience and a copilot. On board were a doctor from Fundeni Hospital, one from Elias Hospital, one from Saint Mary Hospital, another from a hospital in Beiuș, and a student at the Military Medical School in Bucharest. The team were to collect organs from a donor for a transplant operation.

The accident happened in poor weather conditions and the crew was flying according to instrument flight rules. One of the passengers reported the crash at 16:16 in a telephone call to the 112 emergency service. The Inspectorate for Emergency Situations Alba, part of Romanian General Inspectorate for Emergency Situations and the team of Salvamont Cluj was assigned to the rescue operation. The rescue team had difficulty finding the crash site, they did not know the precise location and the area was covered in snow and thick fog. Because of the fog, the SMURD helicopter from Mureș could not be used. Over 70 firefighters and policemen from the counties of Cluj, Bihor and Alba and approximately 200 locals took part in the search for the wreck.

The pilot and the student died and the copilot was in a critical state, three of the doctors had multiple bone fractures and one had no severe wounds. All injured were taken to the Emergency Hospital in Cluj (Spitalul Clinic Județean de Urgență Cluj) and were admitted to the Intensive Care Unit.


Investigation

The Romanian Government announced the start of two investigations. The first would look at the accident and the second the procedures followed by the rescue teams, which reached the scene only several hours after the crash.

In a preliminary investigation report, the Center for Investigation and Analysis for Civil Aviation Security (Romanian: Centrul de Investigații și Analiză pentru Siguranța Aviației Civile) (CIAS) said that the ELT distress beacon was type ARTEX C406-2. This beacon transmitting on frequencies 121.5 MHz, 243 MHz (now obsolete) and 406 MHz, using two different cables for antennas. The cable for 406 MHz antenna was not found at the crash scene, which explains why no signal received on 406 MHz.

LAM Mozambique Airlines Flight 470 (TM470/LAM470) was a scheduled international passenger flight from Maputo International Airport, Mozambique that crashed on 29 November 2013 into the Bwabwata National Park in Namibia en route to Quatro de Fevereiro Airport, Angola. The aircraft operating the flight, an Embraer 190, departed Maputo at 11:26 CAT (09:26 UTC) and was due to land at 14:10 WAT (13:10 UTC), but failed to arrive at its destination. The wreckage of the aircraft was found the following day on 30 November 2013 at the Bwabwata National Park in northern Namibia, halfway between its departure and scheduled arrival airport. All 27 passengers and 6 crew members were killed. Preliminary findings of the Mozambican Civil Aviation Institute (IACM) showed that the pilot intentionally crashed the jet. The Mozambican Association of Air Operators (AMOPAR) disputes the conclusion of the IACM. The Directorate of Aircraft Accident Investigations Namibia stated that the pilot inputting controls leading to the crash was the probable cause of the aviation accident.

It was the first fatal incident for LAM Mozambique Airlines since 1970, and the deadliest for a Mozambican airline since the Mozambican presidential Tupolev Tu-134A-3 aircraft carrying President Samora Machel crashed in 1986


Investigation

On 21 December 2013, the Mozambican Civil Aviation Institute (Instituto Moçambicano de Aviação Civil, IACM) head João Abreu presented the preliminary investigation report, according to which Captain Herminio dos Santos Fernandes had a "clear intention" to crash the jet and manually changed its autopilot settings, making this a suicide by pilot. The aircraft's intended altitude was reportedly changed three times from 38,000 feet (11,582 m) to 592 feet (180 m), the latter being below ground level, and the speed was manually adjusted as well. The cockpit voice recorder captured several alarms going off during the descent, as well as repeated loud bangs on the door from the co-pilot, who was locked out of the cockpit. Contrary to regulations by Mozambique Airlines, no cabin crew member was deployed in the cockpit during the time of the co-pilot's absence.

Investigations of the aircraft's pilot revealed that 49-year old Captain Fernandes had suffered a number of blows of fate prior to the accident. His son died in a suspected suicide in November 2012; Fernandes stayed away from the funeral. His daughter was in hospital for heart surgery at the time of the crash, and his divorce proceedings were unresolved for over a decade.

Despite the conclusion of the IACM, the Mozambican Association of Air Operators (AMOPAR) disputed the preliminary report, explaining that the maneuvers of Captain Fernandes were from the manual of standard operating procedures issued by Embraer (the manufacturer of the crashed aircraft) about how to "act in emergency situation to avert disaster". According to the AMOPAR document, the Mozambican Government had not complied with the standards and recommendations of the International Civil Aviation Organization (ICAO) "about the disclosure, contents and procedures relating to the preliminary report of the investigation of the crash of flight TM 470." On 15 April 2016 the DAAI released its final report finding that the inputs to the auto flight systems by the person believed to be the Captain, who remained alone on the flight deck when the person believed to be the co-pilot requested to go to the lavatory, caused the aircraft to depart from cruise flight, transition to a sustained controlled descent and subsequently crash.

HOME NEWS GALLERY INVESTIGATION ABOUT


Tatarstan Airlines Flight 363 was a scheduled domestic passenger flight, operated by Tatarstan Airlines on behalf of Ak Bars Aero, from Moscow to Kazan, Russia. On 17 November 2013, at 19:24 local time (UTC+4), the Boeing 737-500 crashed during an aborted landing in Kazan International Airport, killing all 44 passengers and 6 crew members on board.

According to the official investigation report, the crash was a result of pilot error, arising from a lack of skill to recover from an excessive nose-up attitude during a go-around procedure. The pilots’ deficiencies were caused by a deficiency in the airline's safety management and a lack of regulatory oversight. One member of the commission filed an alternative opinion report, however, claiming that the commission had ignored the possible malfunction of the aircraft's elevators' controls.


Investigation

The Interstate Aviation Committee (IAC) launched an investigation into the crash and arrived at the site on 18 November. Both flight recorders, the flight data recorder (FDR) and the cockpit voice recorder (CVR), were recovered from the wreckage. The Tatarstan Transport Prosecution Office has opened a criminal investigation into the crash. The American National Transportation Safety Board (NTSB) dispatched a team of investigators to the crash site.

On 19 November, Aksan Giniyatullin, the director of Tatarstan Airlines, declared that although the cockpit crew was experienced, the captain of the airliner may have lacked experience performing a go-around maneuver. Moments before the crash the pilot informed the control tower that the aircraft was not properly configured for landing and initiated a go-around, before plunging into the ground as if it had stalled. Investigators said the possible causes of the accident included technical malfunction as well as pilot error. On 22 November the British Air Accidents Investigation Branch announced they had joined the investigation and had dispatched investigators to Kazan.


Offical report

On 19 November 2013, the Investigation Board of IAC reported the following preliminary details after recovering some information from the flight data recorder: Tatarstan Airlines Boeing 737-500 Accident Technical Investigation Board of IAC informs about preliminary results of flight data recorder information recovery. During the final approach the flight crew were unable to follow a standard landing pattern defined by the regulating documentation. Having considered the aircraft is not lined-up properly relative to the runway, the crew reported to the ATC and started to go-around using the TOGA (Take Off / Go Around) mode. One of the two autopilots, which was active during the final approach, has been switched off and the flight was being controlled manually. The engines reached thrust level close to full. The crew retracted the flaps from 30 degrees to 15 degrees position. Affected by the upturn moment generated by the engine thrust, the aircraft started to climb, reaching the pitch angle of about 25 degrees. Indicated airspeed has started to decrease. The crew retracted the landing gear. Since initiating the go-around maneuver up to this moment the crew did not perform control actions through the yoke. After the airspeed decreased from 150 to 125 knots, the crew started control actions through the yoke, pitching nose down, which has led to stopping climb then starting descent and increase of the airspeed. Maximum angles of attack have not exceeded operational limits during the flight.

After reaching the altitude of 700 meters, the aircraft started a steep nosedive, with the pitch angle reaching −75° by the end of the flight (end of the recording). The aircraft collided with terrain at high speed (exceeding 450 km/h) and with highly negative pitch angle. About 45 seconds have passed between the moment of starting go-around maneuver and the moment the recording stopped, the descent took about 20 seconds. The propulsion systems were operating up to the collision with terrain. No single commands have been detected by the preliminary analysis, which would indicate failures of systems or units of the aircraft or engines. On 24 December 2015, the Interstate Aviation Committee released their final report stating that the crash was caused by an under-qualified crew who lacked the skills to recover from an excessive nose up attitude during a go-around procedure. The go-around was necessitated by a positional error in the navigation system, a map drift. The pilots’ deficiencies were caused by lack of airline safety management and lack of regulators’ oversight.

According to the final report, during the final approach the crew initiated a go-around, but being under high workload, which possibly caused a "tunnel vision effect", they did not perceive warning messages related to auto-pilot disconnection. When the plane climbed to 700 m, its pitch angle reached 25 degrees and the airspeed dropped to 230 km/h. At that moment the captain, who never performed a go-around before, apart from the training, moved the yoke, pitching nose down, which led to stopping climb and started descent and increase of the aircraft's airspeed. After reaching the altitude of 700 m, the aircraft started a steep nosedive, with the pitch angle reaching −75° when the aircraft impacted the ground. The plane crashed on the airport's runway with a speed exceeding 450 km/h. The time from the start of the go-around maneuver until the impact was about 45 seconds, including 20 seconds of aircraft descent.

Lao Airlines Flight 301 was a scheduled domestic passenger flight from Vientiane to Pakse, Laos. On 16 October 2013, the ATR 72–600 aircraft operating the flight crashed into the Mekong River in Pakse, killing all 49 people on board. The accident, the first involving an ATR 72–600, was the deadliest ever to occur on Laotian soil and the third-deadliest involving an ATR 72 behind Aero Caribbean Flight 883 and American Eagle Flight 4184, which both killed 68. It was also the first fatal accident for Lao Airlines since 2000. The investigation report suggests pilot error as the probable cause. The accident was the second-deadliest aviation incident in 2013, behind Tatarstan Airlines Flight 363.


Accident

The aircraft was operating a scheduled domestic passenger flight from Wattay International Airport, Vientiane to Pakse International Airport, Pakse, Laos. The flight departed from Vientiane at 14:45 local time (07:45 UTC) and crashed into the Mekong River at 15:55 local time (08:55 UTC) while approaching Pakse for the second time, less than 6 kilometres (3.7 mi) from the airport. The aircraft had already gone around once due to poor weather and was in the downwind leg for another approach when the aircraft impacted the nearby river.

There were five crew and 44 passengers on board, all of whom are presumed to have died upon impact. Marks on the ground indicated that the aircraft landed heavily on the ground before entering the Mekong. The weather was reported to be poor at the time of the accident due to the remnants of Typhoon Nari affecting southern Laos.

Recovery of the victims and wreckage was hampered by the fast-flowing, deep waters of the Mekong. To assist with the search, 50 divers from Thailand were brought in. Eighteen of the victims had been recovered as of 18 October. By 23 October 44 of the 49 victims had been recovered. Identification had been confirmed for 27 of them. Some of the victims were found 19 kilometres (12 mi) downstream of the crash site.


Investigation

The Laotian Department of Civil Aviation opened an investigation into the accident. The aircraft's manufacturer ATR and the French Bureau d'Enquêtes et d'Analyses pour la Sécurité de l'Aviation Civile (BEA) are assisting them. The BEA sent four investigators to Laos.

The wreckage of the aircraft was lifted from the Mekong on 22 October 2013. More than two weeks after the accident, on 31 October 2013, the Cockpit Voice Recorder was successfully recovered from the Mekong. The Flight Data Recorder was recovered two days later on 2 November.

According to the official investigation report, released on 28 November 2014, the probable cause of the accident was the flight crew's failure to properly execute the published missed approach procedure, which resulted in the aircraft impacting terrain. A sudden change of weather conditions and an improperly executed published instrument approach necessitated the go-around. The recordings show that the flight crew initiated a right turn according to the lateral missed approach trajectory without succeeding in reaching the vertical trajectory. Specifically, the flight crew didn't follow the vertical profile of missed approach as the missed approach altitude was set at 600 ft and the aircraft system went into altitude capture mode. When the flight crew realized that the altitude was too close to the ground, the PF over-reacted, which led to a high pitch attitude of 33°. It then impacted trees. The fuselage struck the bank and plunged into the river.

The 2013 CHC Helicopter Eurocopter AS332 crash involved a Eurocopter AS332L2 Super Puma Mk 2 (G-WNSB) belonging to CHC Helicopters that crashed into the sea 2 nm from Sumburgh in the Shetland Islands, Scotland while en route from Borgsten Dolphin oil platform. The accident killed four of the passengers; 12 other passengers and two crew were rescued. An investigation by the UK's Air Accident Investigation Branch is ongoing.


Accident

The helicopter was on an otherwise normal approach to Sumburgh Airport, when at 18:17–18:20 local time, the aircraft lost contact with air traffic control. No mayday was sent out by the pilots as they attempted to make a controlled ditching into the North Sea, 1.5-2 nm west from Sumburgh. The helicopter fell into the sea and then turned upside down during the evacuation. The helicopter was found broken into several pieces up against rocks at Fitful Head.

Recovered flight data noted by the Air Accident Investigation Branch suggests that the helicopter engines remained powered until impact. The manufacturer's initial analysis based on that data indicated that a combination of factors had placed the helicopter into a vortex ring state at low altitude which made impact "unavoidable".


Investigation

The Police Scotland and Air Accidents Investigation Branch have launched an investigation into the cause of the accident. On 5 September 2013, the Air Accidents Investigation Branch special bulletin reported that there is no evidence of a causal technical failure that could have led to the crash. Both the wreckage and black boxes are still being examined.

UPS Airlines Flight 1354 was a scheduled cargo flight from Louisville International Airport to Birmingham–Shuttlesworth International Airport. On August 14, 2013, the aircraft flying this route, a UPS Airlines Airbus A300-600F, crashed and burst into flames short of the runway on approach to Birmingham–Shuttlesworth International Airport in the US state of Alabama. Both pilots were pronounced dead at the scene of the crash. They were the only people aboard the aircraft.


Investigation

The National Transportation Safety Board (NTSB) launched an investigation and sent a 26-member "go team" to the crash site to "collect perishable evidence". At a press conference held later on the same day, the NTSB said they had been unable to recover the cockpit voice recorder and the flight data recorder as the tail section (where the recorders are housed) was still on fire. Both recorders were recovered on the following day, and were sent for analysis.

At their third media briefing on August 16, 2013, the NTSB reported that 16 seconds before the end of the recording, the aircraft's ground proximity warning system sounded two "sink rate" alerts, meaning that the aircraft was descending too rapidly. Three seconds later, Captain Beal reported having the runway in sight, which was confirmed by First Officer Fanning. The CVR recorded the sound of the first impact with trees 3 seconds after the pilots reported seeing the runway. A final "too low terrain" alert by the GPWS was then recorded, followed by the final sounds of impact. The crew had briefed the approach to runway 18 and were cleared to land by air traffic control two minutes prior to the end of the recording.

To represent the country of manufacture, the French aviation accident investigation agency BEA, assisted by Airbus technical advisors, participated in the investigation.[13] Members of the FBI Evidence Response Team also assisted the NTSB. The NTSB stated in late August that no mechanical anomalies had yet been uncovered, but that the complete investigation would take several months.

On February 20, 2014, the NTSB held a public hearing in connection with its investigation. Excerpts from the cockpit voice recorder were presented, in which both the captain and first officer discussed their lack of sufficient sleep prior to the flight. On September 9, 2014 the National Transportation Safety Board announced that it had determined the probable cause of the accident was that the aircrew had continued an unstabilized approach into Birmingham-Shuttlesworth International Airport during which they failed to monitor their altitude and thus inadvertently descended below the minimum descent altitude when the runway was not yet in sight resulting in a controlled flight into terrain approximately 3,300 feet short of the runway threshold. The NTSB also found that contributing factors in the accident were: the flight crew’s failure to properly configure and verify the flight management computer for the profile approach; the captain’s failure to communicate his intentions to the first officer once it became apparent the vertical profile was not captured; the flight crew’s expectation that they would break out of the clouds at 1,000 feet above ground level due to incomplete weather information; the first officer’s failure to make the required minimums callouts; the captain’s performance deficiencies likely due to factors including, but not limited to, fatigue, distraction, or confusion, consistent with performance deficiencies exhibited during training, and; the first officer’s fatigue due to acute sleep loss resulting from her ineffective off-duty time management.

HOME NEWS GALLERY INVESTIGATION ABOUT




Southwest Airlines Flight 345 was a scheduled flight from Nashville International Airport to New York City's LaGuardia Airport on July 22, 2013. The Boeing 737 suffered a collapse of its front landing gear while landing at LaGuardia Airport, injuring 9 people on board. The aircraft, which was worth an estimated $15.5 million at the time, was written off as a total loss and scrapped as a result of the accident.


Investigation

On July 23, 2013, the National Transportation Safety Board opened an accident investigation. On July 26, 2013, the NTSB issued a press release disclosing its initial findings, which included:

The cockpit voice recorder recorded 2 hours of good data, including the full duration of the last flight from Nashville to New York City.
The flight data recorder provided 27 hours of data, including all parameters for the last flight from Nashville to New York City. From the flight data recorder download:
The flaps were changed from 30 degrees to 40 degrees 56 seconds before touchdown.
The aircraft flared reaching 134 Knots Indicated Airspeed (KIAS) and an attitude of 2 degrees nose-up at 32 feet above ground level (AGL), then 4 seconds later dropped the nose to 3 degrees nose-down at 133 KIAS at touchdown.
The aircraft came to rest 19 seconds after touchdown.
Both the obtained flight data and the available video record have the nose gear making contact with the ground before the main landing gear did, which is the opposite order from the normal landing sequence.

No mechanical malfunctions were found, but the nose landing gear collapsed due to stress overload. The NTSB's investigation became focused on the behavior of the flight crew during Flight 345's approach into LaGuardia Airport. The NTSB discovered that Flight 345's captain had been the subject of multiple complaints by first officers who had flown with her. Southwest's flight operations manual requires its pilots to abort a landing if the plane is not properly configured by the time it descends to 1,000 feet. Analyzing flight recorder data, the NTSB determined that the captain had changed the airplane's flaps from 30 degrees to 40 degrees at an altitude of only 500 feet. At 100 to 200 feet, the captain observed that the plane was still above the glide slope, and ordered the first officer to "get down" instead of aborting the landing. At an altitude of only 27 feet and 3 seconds from touching down, the captain took control of the aircraft from the first officer. The plane was descending at 960 feet per minute in a nose-down position when its nose wheel struck the runway.

The NTSB ultimately concluded that the crash was due to pilot error. Specifically, the NTSB faulted the captain for failing to take control of the aircraft or abort the landing earlier, noting that the captain had warnings at 500 feet (due to the flaps misconfiguration) and at 100 to 200 feet (when the captain observed the plane was above the glide scope) and could have aborted the landing at that time. The NTSB determined that the captain's failure to take control until the plane had descended to only 27 feet "did not allow her adequate time to correct the airplane's deteriorating energy state and prevent the nose landing gear from striking the runway.
