Airblue Flight 202 was a scheduled domestic passenger flight which crashed on 28 July 2010 near Islamabad, the capital of Pakistan, killing all 146 passengers and six crew on board.[2][3][4] It is the deadliest air accident to occur in Pakistan to date.[5][6] The aircraft, an Airblue operated Airbus A321-231 narrow-body jet airliner, crashed in the Margalla Hills north of Islamabad during a flight from Karachi's Jinnah International Airport to Benazir Bhutto International Airport.[7] Air traffic controllers reportedly lost contact with the flight crew during its attempt to land in dense fog and heavy monsoon rain.[8][9]

The accident was the first fatal crash involving an Airbus A321, a long variant of the Airbus A320 family of short to medium range airliners. It was the deadliest accident involving the type until Metrojet Flight 9268 crashed in Egypt in 2015, killing 224 people on board.[10] Based in Islamabad, Airblue is Pakistan's second largest airline, with over 30% share of the domestic market. At the time of the accident the airline operated seven aircraft, all in the A320 family. The accident was the worst one in Pakistan and the second-deadliest aviation incident in 2010, behind Air India Express Flight 812.

Aircraft

The aircraft involved in the accident while still in operation with Aero Lloyd

The aircraft that crashed was an Airbus A321-231, registered AP-BJB,[11] manufacturer's serial number 1218, which was built in 2000. This was the first fatal crash for the A321, and the second hull-loss of the type.[12] The aircraft had originally been delivered to Aero Lloyd and used by Aero Flight before being taken up by Airblue in 2006.[13] It had accumulated more than 35,000 flight hours in some 13,500 flights.[14] The aircraft was previously struck by lightning on 30 December 2008.[15]

Accident

Margala Hills, the crash site of Flight 202

The flight left Karachi at 07:41 local time (02:41 UTC).[2][16] Flight controllers at Benazir Bhutto International Airport lost contact with the aircraft at 09:41 local time (04:41 UTC).[4][7] Weather conditions at the time were marginal, and the captain of a China Southern airliner had diverted to an alternate airport thirty minutes earlier.[17][18]

The aircraft approached Islamabad from the southeast, following a procedure that required it to fly toward the airport until making visual contact. It was then to have flown around the airport to the east and north, keeping within a distance of 5 nmi (9.3 km), until lining up with runway 12, which faces toward the southeast. The aircraft crashed in the mountains outside the 5 nmi (9.3 km) radius, approximately 8 nmi (15 km) north of the airport, facing almost due west, before it could line up with runway 12 for final approach.[19]

While the BBC reported that officials stated that "there was nothing in conversations between the pilot and the Islamabad control tower that suggests anything was wrong",[2] Multiple EGPWS "TERRAIN AHEAD" warnings were recorded on the Cockpit Voice Recorder starting 40 seconds before the crash. The first officer was also heard requesting to the captain "Sir turn left, Pull Up Sir. Sir pull Up."[20]

The pilots did not send any emergency signals prior to the crash.[21] Pakistani Interior Minister Rehman Malik stated that the plane was at 2,600 feet (790 m) as it approached Islamabad but went back up to 3,000 feet (910 m) before eventually crashing.[22] The altitude of 2,600 feet (790 m) was above the safe minimum descent altitude (2,510 feet (770 m) above sea level, or 852 feet (260 m) above ground level) had the aircraft remained within the 5 nmi (9.3 km) radius of the airport.[23][24]

One witness on the ground, who was out walking, stated that "the plane had lost balance, and then we saw it going down".[9] Others described the plane as being lower than it should have been. "I wondered why the plane wasn't flying higher as it was flying towards the hill", one stated. "Then within three or four minutes I heard a loud explosion". Another said that "it was raining. I saw the plane flying very low from the window of my office".[2] Imran Abbasi told The New York Times that he "could tell it was trouble because it stayed so low even though the mountains were up ahead". He stated that the jet was "flying as low as a four-story building".[18] It was reported that Abbasi said that "as the aircraft started to turn, the right side of its front banged into the highest mountain, emitting an instant billow of blue fire and black smoke".[18]

The plane was found near Daman-e-Koh viewing point in the Margalla Hills outside Islamabad.[25] The Los Angeles Times reported that "television footage of the crash site showed smoke and burning debris strewn in a swath cutting through the forest. Rescue helicopters hovered overhead. Fire was visible, and smoke was blowing up from the scene."[9]

The weather conditions nineteen minutes after the accident, as detailed by the 05:00 UTC METAR (aviation routine weather observation message) report for Benazir Bhutto International Airport, were as follows: Wind from 90° (east) at 18 knots (33 km/h). Visibility 3.5 kilometres (2.2 mi), rain, scattered clouds at 1,000 feet (300 m), few clouds at 3,000 feet (910 m) overcast at 10,000 feet (3,000 m). Temperature 25 °C, dewpoint 24 °C. QNH 1006.9 hPa.[26]A

Passengers and crew

There were no survivors.[27] Pakistani footballer Misha Dawood, 19, of Diya Football Club, Karachi,[28] and former national athlete Zafar Saleem, who was director-general of the Sindh Workers Welfare Board, were among those killed in the crash.[29]

The sixty-two-year-old captain of Flight 202, Pervez Iqbal Chaudhry, had 35 years and more than 25,000 hours of flying experience, with an unblemished flight safety record.[27] The comparatively junior first officer (Sqn Ldr) Muntajib Ahmed, a former F-16 Pakistan Air Force fighter pilot, had logged one year of experience on the Airbus A321 aircraft.[30] Of the passengers, 110 were men, 29 were women, 5 were children, and 2 were infants.[22] Six members of the Youth Parliament of Pakistan were on board[18] as were three off duty air hostesses,[31][32][33] and four foreign nationals.[21][34][35]

Rescue attempts

A local police official stated that he had reports "that the plane fell into the Margalla Hills. There is smoke, but we have not been able to reach there. It is surrounded by the hills and there is no road access".[37] An army helicopter arrived to survey the crash site at 10:30 local time (04:30 UTC) but was not able to land. All 152 passengers have been confirmed dead.[2] All hospitals in Islamabad were declared in a state of emergency.[25]

One person present at the scene of the crash stated that the passengers "are badly mutilated and burnt ... and there are two women among the dead". He told journalists that "a good number of rescue workers have reached the site. Other people have reached here on their own. The plane is totally destroyed. The pieces and parts scattered over a large distance. Some parts of the plane are still burning. Some bushes have been burnt."[2] It was reported that rescuers at the crash site were "digging through the rubble with their bare hands."[2] A senior city government official stated that the rescue operation was "very difficult ... because of the rain. Most of the bodies are charred. We're sending body-bags via helicopters."[2]

It was reported, however, that the rescue operation was "chaotic". BBC journalist Zeesha Zafar reported that "there were fewer rescue workers there than one would have expected. A majority of them were members of the anti-terrorism police. Most of them just stood around, gazing at the burning debris, and looking as though there was not much that they could do." He stated that a police officer threatened to baton charge rescuers if they did not "move quickly".[38] Zafar reported that "just when the rescuers were shuffling to get to work, a policeman in plain clothes announced that an army helicopter was coming in to pour water on the fire, and that everyone should get out of the way. The work stopped. The helicopter came, circled on the spot a couple of times, and went away. No water."[38] Zafar went on that it "was distinctly obvious that there was no co-ordination between the workers of different departments such as the police, the rescue department, the Capital Development Authority and the military ... Rescuers operated in a chaotic manner, scouring through the debris that was not on fire ... During the two hours that I stayed at the scene, I saw rescuers collect three separate loads of body parts which they tied up in shrouds. There was no telling how many people they belonged to."[38]

Reaction

A statement on Airblue's website stated that "Airblue, with great sadness, announces the loss of flight ED 202 inbound from Karachi to Islamabad. The flight crashed during poor weather and thick fog. We regret the loss of life and are investigating the exact circumstances of this tragedy. This will be presented as soon as possible." The statement continued that "our hearts go out to the families and loved ones of the passengers and crew."[39] The compensation estimation process for the victims by Airblue's insurer began on 30 July 2010, with initial estimates of Rs 1,000,000 (US$11,169) per victim.[36]

Both the Pakistani President Asif Ali Zardari and Prime Minister Yousaf Raza Gillani sent condolences to the family of those who died in the accident. The Pakistani government declared 29 July 2010 would be a national day of mourning and announced compensation of Rs 500,000 ($5,847) to the family of every victim.[40] U.S. President Barack Obama issued a statement confirming that two Americans had been on the flight and expressing condolences and stated that "our thoughts and prayers go out to all of those touched by this horrible accident".[18] The Air Blue management decided that a monument would be built with the names of the victims inscribed onto it to honor the dead.[41]

Investigation

The Civil Aviation Authority immediately launched an investigation into the accident.[11] Airbus stated that they would provide full technical assistance to Pakistani authorities.[14] A six-member Airbus team, headed by Nicolas Bardou, the company's director of flight safety, arrived in Islamabad on 29 July 2010.[36]

The aircraft's flight recorders were located on 31 July,[42] when Junaid Ameen, the director-general of the Pakistan Civil Aviation Authority, told AFP that "the investigating committee found the black box from the Margalla Hills this morning ... the black box was found from the bulk of the wreckage of the crashed plane." He stated that the box would be examined by "foreign experts" in Germany or France as Pakistan does not possess the equipment to decode the flight recorders. He also stated that the process of extracting information may take six months to a year.[42][43] The Pakistani authorities decided to send the CVR and FDR to the Bureau d'Enquêtes et d'Analyses pour la Sécurité de l'Aviation Civile (BEA) in France.[44]

The report issued by Pakistan's Civil Aviation Authority in November 2011 cited a lack of professionalism in the cockpit crew along with poor weather as primary factors in the crash. In particular, the report noted that the captain ignored or did not properly respond to a multitude of Air Traffic Control directives and automated terrain warning systems. The report also claimed that the first officer passively accepted the captain's actions, after the captain on multiple occasions took a "harsh, snobbish and contrary" tone with the first officer and "berated" him.[45][46]

Representatives of family members of passengers on the flight questioned the validity of the report and the qualifications of those who carried out the investigation.[47]

Sequence of events leading to the crash

An illustration on how a terrain warning (GPWS) system worked. As the aircraft nearing terrain, the warning would sounded.

The Pakistan's Civil Aviation Authority issued the final report on November 2011. The report then stated the chronological order and key events that leading to the crash as follows: [48]

The aircraft took off at 02:52 UTC and the flight crew were served by the cabin crews with a tea and a croissant. During its initial climb, the Captain suddenly tested the knowledge of the First Officer, and used harsh words in snobbish tones to the First Officer. This was very contrary to Airblue's norms. The "questioning and test skills" session went on for minutes. After the humiliating session conducted by the Captain, the First Officer went on silence throughout the flight. It seems that the humiliating session cause the First Officer to lose his self esteem.[49]

After arrived in Islamabad, Flight 202 should line up with the runway centerline to land

Flight 202 later arrived in Islamabad. The flight crews then changed its approach from instrument approach to visual approach. The Captain checked the weather apprehensively, and asked the First Officer to feed unauthorized 04 waypoints in the FMS. The First Officer did not challenge the Captain for his incorrect actions (which may have been caused by the "lecturing session" earlier). The Captain then briefed the First Officer that he would turn the aircraft in the abeam of Runway 30, later to abeam "CF" and then landing. [50]

However, this is contrary to the procedure in Islamabad for visual approach. In visual approach the plane automatically strings a final leg extending the runway centerline. It starts at a waypoint labeled "CF" (start of a Course to Fix leg) created 5 NM from the runway threshold and ends at the runway threshold.[51]

The Captain then requested for a right hand down way visual approach in Runway 12 (which, again, the request being contrary to established procedures at Islamabad Airport), but was not agreed to by the Radar due to procedural limitations. The Captain became worried about bad weather and low clouds on the left hand downwind. The aircraft then started its descent. The First Officer then requested the same request, but wasn't agreed by control tower, and they had to make a left down wind. The Captain later requested again if the right down wind was available, but again wasn't agreed by the control tower.[52]

The Captain wanted to descent to 2.000 ft, but the First Officer reminded the Captain that the Minimum Descent Altitude (MDA) was at 2.500 ft, indicating a possible intentions to the Captain. However, later on, the plane descended through 2.300 ft, and thus violating the MDA of 2.500 ft. After break-off from ILS approach, the Captain ignored the tower controller’s suggestion to fly a bad weather circuit by saying “let him say whatever he wants to say”. The CVR recording and flight simulation show that the Captain probably decided to fly a managed approach unbeknownst to the ATS.

An aircraft Horizontal situation indicator (HSI). The heading indicator could be seen in the picture

The crew commanded a left turn to 300° through the autopilot. This could be done by rotating the heading knob of the aircraft to the heading that the crew wanted and subsequently pulling the knob, thus the plane turned. However, because the crew forgot to pull the knob, the plane didn't turn. Few seconds later, the first "terrain ahead" warning sounded. The First Officer told the captain "Sir higher ground has reached, Sir there is a terrain ahead, sir turn left”. By now the Captain had become very jittery in his verbal communication and displayed frustration, confusion and anxiety resulting in further deterioration in his behaviour.[53]

The Captain later on became confused due to multiple issues in the cockpit, with the tower asked frequently if the aircraft was in visual approach, the imminent collision with terrain, and their plane that didn't want to turn. The pilots were unsure of their geographical position and did not seek Radar help. The consequent loss of situational awareness caused the aircraft to go astray.In an attempt to turn the aircraft to the left, the Captain was setting the heading bug on reduced headings, but not pulling the HDG knob. Since the aircraft was in the NAV mode, the Captain was not performing the appropriate actions to turn the aircraft to the left. The "terrain ahead, pull up!" warning then sounded several times.[54]

The aircraft ended up in a dangerous situation because of most unprofessional handling by the Captain. Since the desired initiative of the FIrst Officer had been curbed and a communication barrier had already been created by the Captain (the humiliating session earlier), the First Officer failed to intervene, take over the controls to pull the aircraft out of danger and display required Crew Resources Management(CRM) skills.[55]

During the last few seconds, the aircraft climbed to 3,090 feet. The Captain put in 52 degrees of bank to turn the aircraft, and also made some nose down inputs. Therefore, the aircraft pitched down, speed increased and auto thrust commanded the engines to spooled down to keep airspeed on the target speed. The aircraft started to descend at a high rate. Unfortunately in his panic, the Captain continued to move the heading knob without actually looking at it, but failed to pull the knob to activate it. When he did activate it, the aircraft turned towards the heading knob that had been rotated overly to 25 degrees until end of recording, and at 04:40:49, Captain said to the First Officer "Why the aircraft is not turning left?" The aircraft then slammed into Margala Hills and exploded. The First Officer's last words could be heard saying to the Captain "Sir we are going down! Sir we are going do--".[56]
