05ce016 - Both Engines Flame-out in TransAsia GE235 Crash

Taiwanese air transport crash investigators state that the right-side Pratt and Whitney turboprop engine went idle on TransAsia Airways flight 235, only 37 seconds after taking off. After this engine allegedly malfunctioned, the flight data recorder revealed, “fuel to the only functioning engine on the left-side was manually cut off,” The Wall Street Journal reports.

The flight data adds to the conjecture that the pilot supposedly in error cut-off fuel to the left-side Pratt and Whitney turboprop engine that would keep the airliner flying. Taiwanese officials have not added information about further interpretation of the flight data, as more specific circumstances causing the TransAsia Airways GE235 crash remain under investigation.

Taiwan’s Civil Aeronautics Administration and TransAsia Airways has confirmed 35 people on board died, as well as, 15 were injured, and eight people — all Chinese nationals — remain missing. Authorities said two people on the ground were hurt.

The Taiwanese Civil Aeronautics Administration released bits of audio recordings including the pilot’s mayday call. According to CNN International and The Wall Street Journal reports, supposedly a pilot on a recording of radio conversations between air traffic control and TransAsia Airways flight GE235 says,

“GE235. Mayday, Mayday. Engine flameout.”

The recording released Wednesday was verified by an independent website, which records air traffic control feeds from around the world. Taiwanese Civil Aeronautics Administration authorities have declined to confirm the name of the pilot, whose voice is heard on the independent website air traffic control feed.

Notwithstanding, Taiwanese authorities have stressed any interpretation of the recording must be done by its Aviation Safety Council, which will lead the investigation and will be the official source of information. According to the United Nations’ International Civil Aviation Organization regulations, TransAsia Airways flight GE235’s aircraft manufacturer, ATR of France will advise the French Bureau d’Enquêtes et Analyses (BEA), the safety investigation authority representing the Sovereign State of the aircraft manufacturer. ATR has expressed its deepest sympathy to the families, friends and to those affected by the accident.

French-built TransAsia Avions de Transport Regional ATR-72-212A, registration B-22816 and Manufacturing Serial Number MSN 1141, performing as TransAsia Airways flight GE-235 from Taipei Songshan to Kinmen (a small resort island near the coast of Taiwan) with 53 passengers and 5 TransAsia Airways flight crew on board, departed Songshan’s runway 10, upon which the airliner was involved in an accident early Wednesday morning, February 4, 2015 at around 10:45 am (local time).

Rescuers scrambled to pull survivors from the submerged wreck of the ATR-72-212A twin-engine turboprop aircraft, which went down shortly after takeoff from the Taiwanese capital.

One injured person was reportedly found in a park along the river, Taiwan News reported. Wu Jun-Hong, a Taipei Fire Department official coordinating the rescue, said he was not “too optimistic” that more survivors would be found.

Earlier Friday, Taiwan’s Civil Aeronautics Administration said TransAsia Airways would be grounded for additional new international flight routes for a year. The Southeast Asia regional air carrier had already been grounded from new international flight routes after a crash involving one of its airliners in July killed 49 people. TransAsia Airways flight GE235 crash extends the grounding period to February 4, 2016, the Taiwanese regulatory agency said.

Photo Credit: JIN LIWANG/ZUMA PRESS. TransAsia Airways flight GE235’s Regional ATR 72-212A airliner black-box was recovered and sent to a lab for analysis by Taiwanese Aviation Safety Council.

“GE235. Mayday, Mayday. Engine flame-out.”

The turboprop engine aircraft is now generally believed to have incurred an ‘engine flame-out‘ moments before the crash in into the Keelung River in Taipei, Taiwan on Wednesday, according to early preliminary analysis of the flight data recorder and independent air traffic control voice recordings of the TransAsia Airways ATR 72-212A airliner.

In an attempt to re-start both turboprop engines, Taiwan’s Aviation Safety Council believes the pilots may have shut off the plane’s left-side turboprop engine upon encountering a right-side engine malfunction immediately 37 seconds upon becoming airborne at takeoff in Taipei. Unfortunately, the pilots did not have enough time before the ATR-72-212A airliner crashed into the Keelung River in Taipei, Taiwan, as air-traffic control lost communication with the plane’s pilots four minutes after takeoff from Taipei’s Songshan Airport.

The exact sequence of both ‘engine flame-out’ events is further confirmed by the Aviation Herald:

“On February 6, 2015 Taiwan’s Aviation Safety Council reported that the investigation so far determined from flight data and cockpit voice recorders:

The aircraft received takeoff clearance at 10:51 (local time). In the initial climb, the aircraft was handed off to departure at 10:52:33.

At 10:52:38 at about 1200 feet, 37 seconds after becoming airborne, a master warning [was] activated, [which is] related to the failure of the right-hand engine.

At 10:52:43 the left-hand engine was throttled back and at 10:53:00 the crew began to discuss engine #1 had stalled.

At 10:53:06 the right hand engine (engine #2) auto-feathered.

At 10:53:12 a first stall warning occurred and ceased at 10:53:18.

At 10:53:19, the crew discussed that engine #1 had already feathered, the fuel supply had already been cut to the engine and decided to attempt a restart of engine #1.

Two seconds later another stall warning activated.

At 10:53:34, the crew radioed “Mayday! Mayday! Engine flame out!”, multiple attempts to restart the engines followed to no avail.

At 10:54:34, a second master warning activated, 0.4 seconds later both recorders stopped recording.”

“Later on February 6, 2015 the Taiwanese Aviation Safety Council also released an English version of the initial release detailing further that when the first master warning activated associated with the right hand engine the crew “called it out”, then the left hand engine thrust lever was progressively retarded to flight idle.

At 10:53:24, the condition lever was set to fuel shut off position resulting in the shut down of the left-hand engine. Following several call outs to restart the left-hand engine, the parameters suggest the left-hand engine was restarted at 10:54:20.

However, at 10:54:34, another master warning sounded, the cockpit voice recorder recorded unidentified sounds and both [the flight data and cockpit voice] recorders stopped.”

Thomas Wang, executive director of the Taiwanese Aviation Safety Council, said “preliminary findings from the aircraft’s black boxes showed the right engine sounded an alarm seconds after taking off, moving into idle mode,” The Independent (U.K.) reports.

Remarkably, the British newspaper added:

“Data showed it had not shut down, or “flamed out,” as the pilot told the control tower in his last “mayday” distress call, but went idle with no change in the oil pressure.

Then, 46 seconds later, the left engine was shut down, apparently by one of the pilots, who then attempted a full re-start. The plane crashed into the Keelung River just 72 seconds later.

Their bodies were found in the cockpit still gripping the plane’s joystick with their legs badly broken, investigators said.

A survivor said the plane did “not feel right” from the moment it left the ground.

“It was too early to draw firm conclusions about the reasons why the engines cut out,” Executive Director Wang said to reporters in Taiwan on Thursday, February 6. “It’s only the third day so we can’t say too much,” he cautioned, “We haven’t ruled anything out.”

Investigators said the engines of the ATR-72-212A had shown no problems before the flight and repeatedly stated that the plane would have been able to take off and fly even with only one engine operating normally.

Earl Chapman, of Canada’s Transportation Safety Bureau, told reporters that the plane’s Pratt & Whitney engines were known for their reliability.

“This engine type has millions of flight hours behind it with a very good safety record. So, it’s fairly unremarkable in that respect,” he added.

“The cockpit flight recorder was still being analyzed and a transcript would be provided as soon as possible,” the Taiwanese Aviation Safety Council executive director Wang stress.

The International Civil Aviation Organization mandates investigators to issue a preliminary report on the crash within 30 days. A more detailed report is expected in the next four months. The final report of the complete crash investigation of TransAsia Airways flight GE235’s French-built ATR 72-212A is not expected until 2016.

Taiwanese Taiwan President Ma Ying-jeou and Vice President Wu Den-yih identified the heroic efforts of TransAsia Airways pilot Liao Chien-chung, at a Taipei funeral service, noting: “When it came to when it was clear his life would end, he meticulously grasped the flight operating system, and in the final moments he still wanted to control the plane to avoid harming residents in the housing communities.”

The Wall Street Journal reports: At a memorial service Thursday, Taipei City Mayor Ko Wen-je paid respect to the pilot, Liao Chien-tsung, who died in the crash. Mr. Ko said the pilot saved thousands of lives by directing the plane away from a bustling area in its descent path —including a subway station, a hospital, a busy highway and Nankang Software Park, which houses a cluster of technology companies.

By now all the world has seen the stunning photo and YouTube video, showing a TransAsia plane clipping a road before crashing near Taipei, Taiwan, today. Images taken from video provided by TVBS shows the French-built ATR 72-212A plane’s final moments in the air captured on car dashboard cameras do not appear to show flames as it turned sharply, with its wings going vertical and clipping a highway bridge before plunging into the Keelung River in Taipei, Taiwan on Wednesday, February 4, 2015, according to the island’s official news agency, CNA.

Is Flying in Southeast Asia Becoming Risky?

One of my thousands of followers on Twitter, Kerry Barrett (@Kerry Barrett) poignantly brought to my attention a very relevant question on what non-pilots and air transportation consumers think, when they hear breaking news about an airplane stalling or an ‘engine flameout‘.

And, what does an aircraft stall actually mean to the flying public, as they try to understand the stunning pictures of the TransAsia Airways flight GE235 crash into the Keelung River in Taipei, Taiwan on Wednesday, February 4, 2015, or the extraordinary final three minutes of the AirAsia flight QZ8501 crash into the Java Sea off the coast of Indonesia on Sunday, December 28, 2014.

Such extreme events in rapid succession begs the question “is flying in Southeast Asia becoming risky?”

According to USA Today: “It turns out flying in Asia is actually riskier than in any other region but Africa. Why? Regulatory regimes there are less advanced than in the United States and Europe (Japan is considered as safe as the west). Another factor is that international regional airlines, such as TransAsia Airways, tend to use less-experienced pilots than major airlines.”

Nonetheless, TransAsia Airways reported on Thursday, February 5 that the two pilots at the controls of flight GE235 had 4,914 hours and 6,922 hours total flying experience, an instructor with 16,121 hours total occupied the observer’s seat, according to Aviation Herald. The crew had signed the flight papers, that showed no unusual circumstances.

“It’s not like they’re the wild west, like you might get in some African countries, but they are 10 or 20 years behind,” said Justin Green, a New York aviation lawyer with Kreindler & Kreindler. “If you’ve never heard of the airline that your travel agent is booking you on, you should do some research.”

AAEAAQAAAAAAAAKKAAAAJDg2NGZhNDBhLWY4YzEtNDZjMi04ZDYzLWNhMDQ0ODMzNmI5Yw - Both Engines Flame-out in TransAsia GE235 Crash

Aviation expert David Learmount, operation and safety editor at Flight Global, says it is clear from the video footage that TransAsia Airways flight GE235’s French-built ATR 72-212A airliner was ‘fully stalled’.

In a blogpost on the possible causes of the crash, Learmont writes:

“An aircraft stalls because it’s flying too slowly to generate sufficient lift from its wings and it starts to fall.

If an aeroplane is flying too slowly in level or descending flight, it is normally because there is insufficient power to keep the aircraft’s speed up. The question for the investigators is why was there insufficient power?

Reports are coming in that the pilots made a Mayday call declaring an engine flameout.

Both propellers were clearly turning, but that does not necessarily mean they were being supplied with sufficient power to fly safely.

If engine power is lost, the un-powered propeller can cause a lot of drag by windmilling, making the aircraft too difficult to handle. Under those circumstances the crew would normally “feather” the propeller to cut the drag.”

Taiwan’s Aviation Safety Council on Friday, February 6, 2015 said flight GE235 issued five speed-loss warnings before crashing. This is the essence of the key cause of the crash, mainly because fundamentally non-dimensional engine thrust is a sole function of the turboprop engine flow velocity ratio. This is a ratio of the engine exit flow velocity of the air slipstream far downwind of the turboprop to the engine inlet flow velocity of the air slipstream far upwind of the turboprop.

Closely related to this is the non-dimensional engine thrust power, which is a sole function of the square of the turboprop engine flow velocity ratio. Without engine thrust power coming from either one of TransAsia Airways flight GE235’s French-built ATR 72-212A turboprop engines, aircraft stall is imminent, resulting in the stunning last photos and dash cam videos gone viral online and widely seen on international broadcast media.

Role of Human Factors in Automated Flight Management Efficiency and Decision-Making

It is essential to have pilots involved in the flight management automation design. “Humans aren’t good monitors of rare events, and monitoring can be a boring job especially for a long haul flight. In some cases pilots have wanted to remove just part of the automation and utilize the remaining features, but are unable to do so, because ‘all or nothing’ are the only options,” says the longstanding authority in the field of human factors in modern aviation, Orlady, H. and Orlady, L. (1999) in Human Factors in Multi-Crew Flight Operations.

A very real problem involved with the almost complete automation present is pilot complacency and over-reliance upon automation. This pilot response occurs in normal operations and also is reflected in the pilot’s reliance on the system to automatically make the correct response during abnormal operations and flight management efficiency inside the crisis of a crash event. Flight crews tend to rely upon the automation to the point that the normal checks that are inherent in good manual operations are sometimes disregarded (Orlady and Orlady, 1999).

To overcome this problem, the design of automation has required:

  • “The automated systems must also be able to monitor the human operator and the human must be able to monitor the automatics.

This emphasizes two real problems, first, humans are fallible and are not the perfect monitors because of human limitations. Secondly, even the highly capable computers available today can fail partially or completely and cannot anticipate all of the circumstances that might be encountered in a line operation. Therefore, the performance of the computers and the human operators must be monitored by each other. For example, the computers should be able to send warning signals when human operator has made an error, and at the same time, when the automation is making incorrect decisions, humans need to understand and be aware of it.”

  • “Each element of the system must have knowledge of the others intent.

A very basic principle in cross-monitoring, which must be effective in achieving maximum safety, is that it can only be effective if the monitor knows what the system is trying to accomplish. This principle requires good communication between the pilot flying and pilot-not flying for it is virtually impossible to be sure of intent without effective communication.”

“The issue of safety due to automation that arises due to the pilot or controller making rare errors can be reduced by having two pilots in the cockpit who are well trained to monitor the automatics as well as monitoring each other’s operational performance during flight. This process of monitoring both the systems performance along with the pilots performance is further improved by the automated warning systems in the cockpit,” writes Orlady and Orlady (1999).

Technical speculation suggest at this point the severe weather-related conditions may have most allegedly caused some degree of human factor errors, mostly likely revealed from the flight deck conversations and flight performance data and information gained from AirAsia flight 8501’s Airbus A320-200 black-boxes still to be completely analyzed and transcribed for the crash final report expected to be released early next year.

Human factor errors are typically the result of ninety percent of catastrophic aviation accidents, according to years of research by the United States Federal Aviation Administration and the National Transportation Safety Board.

However, the AirAsia flight 8501 crash final report could allegedly reveal additional future learning factors of aviation, navigation, and communication that in this extreme case was driven by the extraordinary monsoon-like cumulonimbus cloud conditions, extending at such high altitudes at 44,000 feet (beyond normal commercial passenger aircraft operating ranges), allegedly creating such a perfect storm event for a naturally catastrophic air disaster upon a commercial passenger airliner.

Indonesia’s National Transportation Safety Committee chief Tatang Kurniadi told reporters back in January, “if one wing engine had stalled, the plane could spin out of control as it plummeted toward the water.”

However, he said that “only the data from the black boxes would ultimately determine what happened to flight 8501, and he declined to say whether the plane had in fact stalled.”

Mr. Tatang said “the comments made by Transport Minister Ignasius Jonan to Parliament in January “were based not on data from the black boxes, but on the ground radar.” Indonesia investigators have now confirmed the transportation minister’s comments made in January.

Notwithstanding, recent aviation disaster history confirms an excessively rapid ascent is indeed likely to cause an airplane to go into an aerodynamic stall.

In 2009, an Air France flight AF447 Airbus A330-200 disappeared over the Atlantic Ocean in bad weather, while flying from Rio de Janeiro to Paris.

Investigators determined from the jet’s black boxes that it began a steep climb and then went into a stall from which the pilots were unable to recover, The Independent (U.K.) reports.

A synopsis of what occurred during the course of the doomed Air France AF447 Airbus A330-200 airliner’s final few minutes is here.

Airbus spokesman Justin Dubon said that it was too early to comment on possible similarities between the two crashes.

Mardjono Siswosuwarno, chief investigator of Indonesia’s National Transportation Safety Committee, said the flight data recorder, which was recovered from the Java Sea along with the cockpit voice recorder earlier this month, had provided a “pretty clear picture” of what happened in the final minutes of AirAsia flight 8501.

Captain Plesel was in charge from take-off until the cockpit voice recording ends, Siswosuwarno said.

“The second-in-command was the pilot flying,” Siswosuwarno said to reporters in Jakarta, adding that “the captain was monitoring the flight,” and that “this was common practice.” He also said that “the plane was in good condition.”

“Things may have gone wrong in a span of just three minutes and 20 seconds, triggering a stall warning that sounded until it crashed into the Java Sea,” investigators of Indonesia’s National Transportation Safety Committee further elaborated in a news conference in Jakarta, Indonesia on Thursday, January 29, 2015, via CNN International.

According to Reuters, Captain Iriyanto was out of his seat and conducting an unusual procedure on the Flight Augmentation Computer (FAC) when his co-pilot, Remy Plesel, lost control. By the time Iriyanto returned, it was too late to save the plane.

The FAC is a “fly-by-wire” device of the Airbus A320 airliner that uses a computer to control a flight process in order to increase airliner flight safety and reliability, as well as flight management efficiency, while reducing the need for human intervention.

In other words, the FAC is designed to ensure normal operation of the aircraft within specific computerized flight safety envelops independent of any alleged human factor errors resulting from possible pilot inputs. FAC “fly-by-wire” devices can supposedly in extremely rare instances affect “operator” decisions, whose primary responsibility shifts from being the “performer” in flight operations to being the “onlooker” in flight management efficiency.

Whereby, the concerns of “complacency” can potentially arise in flight management decision-making with increasing level of automation in modern aviation, particularly in flight and air traffic control operations.

Iriyanto reportedly had previously flown on the Airbus A320 and experienced a faulty FAC, which he apparently went to fix. Reuters was unable to offer independent confirmation of the faulty device.

After trying to reset the device, pilots pulled a circuit-breaker to cut its power, Bloomberg News reported on Friday, February 6, 2015.

“You can reset the FAC, but to cut all power to it is very unusual,” one A320 pilot, who declined to be identified, told Reuters. “You don’t pull the circuit breaker unless it was an absolute emergency. I don’t know if there was one in this case, but it is very unusual.”

Pulling the circuit breaker is also an unusual move, because the captain would have had to rise from his sea

President Joko Widodo said the crash exposed widespread problems in the management of air transportation in Indonesia.

Now is the Time for Consensus on Recommendations on the Future of International Aviation Safety and Security

Countries and regions with the highest number of fatal civil airliner accidents from 1945 through November 30, 2014 (excluding MH370, MH17, AirAsia 8501, and TransAsia GE235) are:

United States, 773; Russia, 326; Canada, 177; Brazil, 176; Colombia, 173; United Kingdom, 103; France, 101; Mexico, 96; India, 94; Indonesia, 94; China, 74; Italy, 67; Venezuela, 61; Philippines, 60; Bolivia, 60; D.R. Congo, 60; Germany, 58; Peru, 56; Spain, 51; Australia, 48.

In just the past year (2014-15), we have lost the lives of over 734 international passengers and flight crews in Southeast Asia (which amounts to about three times more than all fatal civil airliner accident in the last 68 years between 1945-2013) on four compelling global aviation crash events.

These include the oceanic loss of a Boeing 777-200ER airliner, flown as Malaysia Airlines flight MH370 on March 8, 2014, the shooting down over a war-torn eastern Ukraine region of a Boeing 777-200 airliner, performing as Malaysia Airlines flight MH17 on July 17, 2014, a crash in the Java Sea off the coast of Indonesia of an Airbus A320-200 airliner, operating as AirAsia flight QZ8501 on December 28, 2014, and a crash in the Keelung River in Taipei, Taiwan of a French-built ATR 72-600 (72-212A), flown as TransAsia Airways flight GE235 on Wednesday, February 4, 2015.

According United States Department of Transportation; Federal Aviation Administration (Office of Aviation Policy and Plans), statistics show average estimated annual growth in passenger traffic to and from the United States transported by U.S. and foreign flag air carriers between 2014 and 2034, by region.

During this time period, passenger U.S. air traffic to or from Latin America is estimated to grow by around 4.7 percent per year. Passenger air traffic in the Asia Pacific region is predicted to grow by about 4.2 percent per year. The Atlantic Oceanic air traffic is projected to grow by nearly 4.1 percent per year. And, the Canadian trans-border is believed to grow by about 3.8 percent per year.

Forecasts are based on historical passenger statistics from the United States Immigration and Naturalization Services (INS) and Transport Canada, and on regional world historical data and economic projections from Global Insight, Inc.

International commercial passenger air travel is expected to explode in the next decade (according to both federal government, and Boeing and Airbus industry projections), particularly in Southeast Asia. This region is highly dependent upon air travel across deep seas and remote oceans for millions of people in the Southeast Asia and Oceania region.

Given this consensus must be reached on recommendations of human factor errors of complacency, over-reliance, and over-confidence bias (a “winner’s curse“) in flight management efficiency and flight systems automation, global flight tracking of commercial passenger airliners, jet black-box data streaming, and ejectable flight data recorders.

All of this calls for further consensus to be reached quickly among airline chiefs, aviation experts, and government officials, who have just completed their discussions at the International Civil Aviation Organization (ICAO) “Second High-level Safety Conference” on February 2-5, 2015 at its headquarters in Montréal, Canada.
