According to Carbaugh, the official said: “The report is coming out. Boeing is aware of this academy and feeder facilities just like it all over the world. The second accident occurred when Ethiopian Airlines Flight 302, a 737 Max bound for Nairobi with 157 people aboard, hit the ground near Addis Ababa in a screaming dive. The dilemma is familiar to manufacturers after major accidents in which it is usually some pilot and not an airplane that has gone wrong. The captain informed the co-pilot and said that he himself would do the flying. The only control problem they had was some hand-flown sloppiness from Suneja, who allowed a minor drift-down to occur before continuing with the climb. The captain flipped the switches, the trim stopped running away and the MCAS was disabled. The Indonesian National Transportation Safety Committee (KNKT) final Lion Air JT610 737 MAX accident investigation report lists 89 findings explaining what factors caused the aircraft to crash … Trim is routinely adjusted in flight. It is hard to imagine what the controller was thinking. While flying through an area of bad weather at 35,000 feet, the crew noticed discrepancies between the navigational systems; while fiddling with a solution, they switched off the autopilot unintentionally and drifted into a bank that turned into an uncontrolled spiral dive, during which the descent rate exceeded 50,000 feet per minute and the airplane approached the speed of sound before the captain pulled the wings off in flight. Nonetheless, by last Oct. 29, Suneja had accumulated 6,028 hours and 45 minutes of flight time, so he was no longer a neophyte. A few months earlier, another Boeing-737 Max crashed in Indonesia, still a few minutes after take-off, killing the 189 people aboard the 610 Lion Air flight. He didn’t tell the captain?”. While Boeing says it has made significant progress in returning the 737 Max … The Boeing 737 Max is, in essence, an upgrade to the most popular plane in the sky, the Boeing 737. The more important point was that Adam Air no longer posed a threat to the flying public. John Goglia, with his vast knowledge, shared my concerns. But did they get exposed anywhere else? display: none !important; He would call the airline Lion Air. Under the title “Boeing Correspondence: Multi Operator Messages,” it sent a two-paragraph email that named the MCAS for the first time. April 25, 2019 By Luca Tamburelli Leave a Comment. He didn’t know what he was doing? during the airplane’s testing and certification process. The story is complicated because the counter-trim that Suneja had been thumbing to beat back the dog was working, and with greater effect at higher speeds, to the point that full nose-down trim would have been avoidable even if the cutout switches were not thrown, so long as the pilots stayed in the fight. It’s a scandal.Join the Video Lab! They were about six minutes into the flight and still on the runway heading. Lion Air’s fleet grew by even larger multiples as the airline gobbled up an increasing share of the market, and Kirana turned out to be a master of financial dealings. The controller did not provide a holding point but asked about the nature of the problem. On the corporate level, the company is the worst sort of player — a corrosive agent that spreads money around Washington, pushes exotic weapons on Congress, toys with nuclear annihilation, sells all sorts of lesser instruments of death to oppressive regimes around the world and dangerously distorts American society in the ways that President Dwight D. Eisenhower warned against in his prescient 1961 farewell address. JOIN OUR AFFILIATE PROGRAM What little the Indonesian investigators have said about the voice recordings, they have described that much. Immediately after liftoff, the captain’s airspeed indication failed, airspeed-disagreement and altitude-disagreement warnings appeared on his flight display and his stick shaker began to rattle the controls in warning of an imminent stall. Executives couldn’t keep up with the 787’s complex manufacturing process. The system in question is complicated, and we will return to it later, but for now it is enough to know that after the loss of Lion Air 610, the company suggested that the 737 Max was as safe as its predecessors. To them the event must have looked like a runaway trim, much as Boeing had expected. They leave the airplane. Boeing believed the system to be so innocuous, even if it malfunctioned, that the company did not inform pilots of its existence or include a description of it in the airplane’s flight manuals. But no, he stuck obediently to 5,000 feet, left the throttles forward and retracted the flaps. JULY 7 - Boeing has reached settlement agreements in more than 90% of the wrongful death claims filed in federal court after the 2018 Lion Air 737 MAX crash in … The logic of those conditions is clear, but not worth the digression here. “Those were the rote pilots,” he said, “the guys standing up in the back of a sim. and whisked to Paris. The 737-500 does not share the same antistall system as the 737 Max, which was triggered in the 2018 crash of another Indonesian flight, Lion Air Flight 610, killing all 189 people aboard. The airline did not provide investigators with the identities of its pilots and was not forced to. But when the industry was deregulated shortly afterward, Kirana could not be denied. The implicit insult won him the enmity of some French airline pilots, who then as now thought highly of themselves. Stick shakers are designed to … Appropriately, the controller acknowledged Suneja’s transmission without quibbling and responded, “No restriction.” He meant that Suneja was cleared to fly at whatever altitude he chose. The process in Jakarta has been similarly problematic. Yet if they flew from Beijing to Guangzhou, it was 1,550 steps. A small number of Boeing's Max 9s are also operating. The worst of them are intimidated by their airplanes and remain so until they retire or die. By the 1980s, however, the situation had evolved. One reason for them is that no one expects a pilot to go out and crash the next day. Both Boeing and Airbus had taken larger such actions before. Privately, it would start working on a fix for the MCAS. By far the largest number of defects was related to discrepancies between the airplane’s two independent inertial reference systems, navigational and flight instrumentation drivers that are important to the safe completion of a flight. The thumb switches control an electric mechanism that changes the angle of the horizontal stabilizer — the all-important tail surface that counteracts the natural pitching effects of the wings and provides the necessary aerodynamic balance for flight. Such failures are easily countered by the pilot — first by using the control column to give opposing elevator, then by flipping a couple of switches to shut off the electrics before reverting to a perfectly capable parallel system of manual trim. [Read highlights from The Times’s coverage of the 737 Max crashes and the fallout.]. Foremost were their epic interventions in China that gathered speed in the late 1980s and endured for years. Some at Boeing argued for an aerodynamic fix, but the modifications would have been slow and expensive, and Boeing was in a hurry. He said: “They didn’t finish, whatever the log says. It remains unclear exactly what went wrong at Boeing — who decided what, and why — but a small collective breakdown had obviously occurred, and the F.A.A. Here’s what happened. Ethiopian Airline crash was preceded by the Lion Air fatal flight of the Boeing 737 MAX in October, 2018. The ban was largely symbolic, because the Indonesians were focused on their expanding regional markets and had no immediate plans to open such long-distance routes, but it signaled official disapproval of Indonesia’s regulatory capabilities and served as a public critique of a group of airlines, some of which were out of control. 3. This is another of Boeing’s bewildering failures — the implementation of an automated nose-down input meant to make for an authentic control feel but allowed to keep at it again and again while throwing the airplane wildly out of trim. Finally the ghost in the jump seat intervened. As for Lion Air, having begun with Boeing, it stuck with Boeing and by 2005 placed an order for up to 60 Next-Generation 737-900ERs. Boeing called the result the Max. have been largely excluded and denied access to such basic evidence as the complete flight-data recording and full access to the audio files from the cockpit, though representatives from the N.T.S.B. I have been unable to speak to Kirana despite multiple attempts to reach him, so I do not know if he cares about these distinctions. The effort was made not out of the goodness of the manufacturers’ hearts, but out of calculations related to risk and self-preservation. Boeing test pilots discovered that the Max had unusual stall characteristics when the wing flaps were up and the engines were thrusting. Angle-of-attack vanes are exposed to the winds and are vulnerable to impact, ice and wear. “They look down on my airline and my country,” he told Reuters. The airplane landed long, touched down going 100 miles an hour too fast, bounced three times and went careering off the far end of the runway, slicing through an airport perimeter fence and sliding across a road, a ditch and an embankment before coming to rest in a rice paddy and bursting into flames. Airline crashes are rare, and rarer still are crashes that force the grounding of an entire fleet. FAA Certifies the Boeing 737 … The formal investigations continue today, and you might hope that their findings would lead to a more complete understanding of the accidents. The following year, American Airlines warned that it might abandon Boeing and buy hundreds of the new Airbus models. Carbaugh mentioned to me that he was serving as Boeing’s chief pilot of safety in 2010 when an Ethiopian crew lost control of a 737 NG, the predecessor of the Max, killing all 90 people aboard. The model was unpopular and had garnered not a single customer before Lion Air came along. were allowed to listen to recordings Important leads, meanwhile, are not being pursued, entire angles are being overlooked and the release of information to the public has been unusually restricted. Boeing assumed that if necessary, 737 Max pilots would flip them much as previous generations of 737 pilots had. As a reminder, the horizontal stabilizer is the large tail surface that can be angled down or up by the trimming mechanisms to change the airplane’s pitch; the “elevators” are the hinged control surfaces mounted behind it and are manipulated by the use of primary controls to adjust the pitch. Trim refers to an aerodynamic condition related to pitch — the nose-up-or-down attitude of an airplane in flight. But pitching up into a stall is a characteristic of all jets with underslung engines, and the tendency in the Max, though slightly stronger than in previous 737s, was probably not sufficiently different to rouse the F.A.A. When I asked how the completion rate could be so high, the head of training explained that it is because of aptitude testing at the start. The Bali captain was enough of an airman to realize that he was dealing with an information failure only — not an actual stall. Airplanes fly because their wings greet the oncoming air at a positive angle, known as an angle of attack. ^ "Lion Air 737 Max 8 crash confirmed, 189 dead". He had accumulated about 900 hours of flight time when he was hired by Lion Air. And there was a problem. On board were three crew members but … This was done for reasons of safety. During intervals on the ground, the airline’s technicians ran built-in tests, got coded responses and did plug-out plug-in reboot attempts of the mindless sort performed at automotive service centers. The tuition is $60,000. The company seemed hesitant to point the finger at a prickly customer — Lion Air — that had several billion dollars’ worth of orders on the table and could withdraw them at any time. Either way, he recommended the obvious — shutting off the electric trim by flipping the cutout switches. On this leg, he would handle the radio communications. Harvino dutifully responded. Since then, he had gained another 207 hours. Investigators later determined that the Air France flight — a heavy jet stalling at absurdly high angles of attack — passed the point of possible recovery as it mushed down through 12,000 feet. They wrote, “Installation test and heater test result good.”. Our mechanics laughed about “pencil whipping” the airplanes into the air, and we agreed that the paperwork was a joke. It would be at most a 30-second event. Second, if the software makes the plane nose down, there is a procedure for its trajectory. One winter night, one of our pilots died. The Max’s stall characteristics, which indirectly bear on the accidents, have been widely reported as being an unusual tendency to pitch up when the airplane is flown at high angles of attack, in realms beyond the stick shaker where airline pilots never go. They saw where and how it was handled in the curriculum — always on Sim Ride No. They had a stick shaker sounding off and some unreliable indications, but the still-unknown MCAS had not yet engaged because the wing flaps remained extended. The second angle-of-attack sensor was functioning correctly. Airbus has gone further than Boeing in acknowledging this reality with its robotic designs, though thereby, unintentionally, steepening the very decline it has tried to address. Simulators, shop equipment, stocks of spare parts and training curriculums have to change. A shareholder lawsuit filed on Monday accused Boeing Co's board of doing nothing to investigate the safety of the 737 MAX until the fast-selling plane suffered a second deadly crash in five months. It is widely seen to have been a success. But none of this was quite true. Private jets and airliners, an ecological hydrogen future? If the pilot does not respond, the airflow starts to boil across the top of the wings, sometimes causing buffets that shake the airplane, before separating from the wings conclusively at the moment of the stall. But about four months later, on March 10, 2019, an equally new 737 Max flown by Ethiopian Airlines went down on departure from Addis Ababa with the loss of everyone aboard, and within a week all further flights of the 737 Max were stopped worldwide. To point fingers at important clients would risk alienating not only those airlines but others who have been conditioned to buy its airplanes, no matter how incompetent their pilots may be. What sent an expensive new Boeing into the ocean on that beautiful, bright morning in Indonesia? Furthermore, it is certain that thousands of similar crews are at work around the world, enduring as rote pilots and apparently safe, but only so long as conditions are routine. The 737 features two prominent toggle switches on the center pedestal whose sole purpose is to deal with such an event — a pilot simply switches them off to disengage the electric trim. These broader implications, however, have been lost in the noise. They need to say that an Israeli shoot-down or a bomb was a possible cause of the accident.”, Carbaugh told me that he answered: “Sir, here’s the data. The air-traffic control record shows the same. This is unlikely and has never been explained. Speaking about Adam Air, Dave Carbaugh, a former Boeing test pilot and one of the world’s top aviators, who trained airline pilots throughout Asia, told me: “They kept dispatching a faulty aircraft. In 2007, the European Union and the United States permanently banned all Indonesian airlines from their national territories. Each is led by government officials of the countries where the airplanes crashed — Indonesia and Ethiopia — and joined, respectively, by Lion Air and Ethiopian Airlines, by Boeing as the airplane’s builder and by the N.T.S.B. The Boeing 737 Max is the latest version of the popular Boeing 737 airliner. The only way to retrim the airplane at these speeds would be to use the much more powerful electric mechanism associated with the thumb switches, which, however, would require the pilots first to flip the cutout switches back to “normal,” exposing the airplane to further attacks from the MCAS. But at some point, the angle of attack becomes too great for the oncoming air to negotiate smoothly. The reason crashes never happened during other stages of flight is most likely that the autopilots were engaged. But it seemed that for some reason, the Lion Air crew might not have resorted to the simple solution. Those two switches are still off? That threatened to change in 2010 when Airbus introduced a version of the 320 called the Neo (for “new engine option”) that offered large improvements in fuel efficiency, range and payload. I was told that in Indonesian simulators, there are sometimes seven in there: two pilots flying, one instructing and four others standing up and logging the time. Lion Air and Ethiopian Crashes Differ. When Harvino mentioned a “flight-control problem,” he was wrong. None of it worked here, but the technicians kept zeroing the fault messages and approving the airplane for flight. Airplanes are living things. The surprise was that after the assault ended, the MCAS paused and came at him again and again. After both accidents, the flight-data recordings indicated that the immediate culprit was a sensor failure tied to a new and obscure control function that was unique to … Although the results of both investigations pointed out to one mutual link related to the faulty MCAS system, the rest of the factors contrasted. Airmanship 101. That’s not what happened. For instance, applicants must have graduated from high school. He was an off-duty pilot and, according to one Indonesian pilot I spoke to, a 737 Max captain for a Lion Air subsidiary. On occasion, however, it may start running on its own volition and prompt the airplane to nose up or down. As always, there was a problem with like-mindedness and a reluctance by team players to stand out from the crowd. The French, Americans and Lebanese all agreed that it was complete. The respective crews wrote them up repeatedly. The subsequent investigation was led by a brilliant Lebanese airline pilot named Mohammed Aziz, who after nearly two years of obstructionism and obfuscations by the Ethiopians produced a report laying the blame squarely on the pilots, who had overshot assigned compass headings left and right, overbanked repeatedly, stalled twice and, for lack of airmanship, entered a lethal high-G spiral dive. They are as common as they are difficult to discern. Everything seemed fine during the takeoff roll, but as soon as he hauled back on his control column and the airplane lifted off, the angle-of-attack sensor went haywire, the stick shaker began to rattle the left-side controls and Suneja lost reliable indications of airspeed and altitude on his flight display. Given the scope of the night’s events, the report was so off-base that I questioned whether any of the recorded maintenance had even taken place. “They treat us as third-world.”. When I asked a senior investigator about the omission, he explained that it was because the investigators had been busy. He told me that a senior official from Ethiopian Airlines asked him to come to his office for a private talk. By trim failures, I mean runaway trims. I asked him, ‘How come?’ He said, ‘Because the checklist doesn’t say to divert.’ ”. repeated the same information in the form of an “Emergency Airworthiness Directive,” a regulatory mandate to change the airplane’s flight manual.
