43:44. [21] One pilot radioed, "That plane has just started to do a big huge plunge." Following the procedures prescribed in the checklists, they tried cycling the motors on and off, checking the trim motor circuit breakers, and using the manual trim controls. SkyWest 5154, you still got your eyes on him, sir?. A special inspection by the FAA after the accident found further evidence of a massively deficient safety culture at Alaska Airlines. Three years before the accident, the airline asked Boeing if it could use Aeroshell 33 on the jackscrew. I clicked it off, Thompson said. [23] In addition, both engines, as well as the flight data recorder (FDR) and CVR were retrieved. Many did not apply grease to the entire length of the jackscrew as per the procedure. An FAA inspector who reviewed the 1996 extension said that the airline presented only Boeings recently extended lube interval as justification. For two hours, the crew of the ill-fated jet had struggled with a malfunctioning stabilizer, unaware that this critical flight control system had turned into a ticking time bomb counting down toward catastrophic failure. The airplane immediately began another dive except this time it did not recover. Two other airplanes had severely worn acme nuts, both from Alaska Airlines. "[21] Although the CVR captured the co-pilot saying "mayday", no radio communications were received from the flight crew during the final event. Having decided not to touch the trim system anymore, the crew now performed some final tests of the airplanes low speed handling. On January 31, 2000, the aircraft operating the route, a McDonnell Douglas MD-83 . [11] Of the passengers, one was Mexican and one was British, with all others being U.S. The trim might be, and then it might be uh, if somethings popped back there. In July 1996, the criteria was changed to 8 calendar months which equated to 2,550 flight hours. Later, the NTSB found that while "the flight crew's decision to divert the flight to Los Angeles was prudent and appropriate", "Alaska Airlines dispatch personnel appear to have attempted to influence the flight crew to continue to San Francisco instead of diverting to Los Angeles". And while the airline did eventually settle the suits, it did so only after dragging the families through what many described as a legal hell in which Alaskas lawyers tried to downplay the monetary value of their deceased loved ones. Uh, its a lot worse than it was? Tansky asked. It was my job to find out.

In order to catch abnormal wear before it escalated to the point of failure, MD-80 operators regularly inspected their stabilizer jackscrew nuts to ensure that the wear remained within limits. At this point the checklist said Consider stab jammed, do not use autopilot, and offered a list of considerations to be made during landing. During the course of the investigation and in its final report, the NTSB issued a large number of recommendations, including that the lubrication procedure for the MD-80 series jackscrew be revised; that a more accurate method of measuring wear on the jackscrew be developed; that maintenance technicians be specifically taught how to grease and inspect jackscrews; that the FAA not approve lubrication interval extensions without the airline providing supporting data; that all airlines be surveyed to ensure compliance with jackscrew lubrication procedures; that a bulletin be issued instructing pilots not to troubleshoot inoperative flight controls; that maintenance personnel and dispatchers be trained not to suggest continuation of a flight that is experiencing a major malfunction; that the jackscrew be made easier for maintenance workers to access; that an inspector be required to sign off on every lubrication of the jackscrew; that all maintenance intervals for critical components be re-examined based on data analysis to ensure that they are not too long; that the application process for maintenance interval changes be reformed; that MD-80 series jackscrew inspections be made on a tighter schedule; that some failsafe mechanism be incorporated to ensure the redundancy of the MD-80 jackscrew; and that the FAA ensure future stabilizer designs cant have a single point of failure. Then in 1999 Alaska Airlines retaliated against John Liotine, putting him on indefinite leave from his job and circulating false rumors about him; the airline sought to portray him in the media as a disgruntled employee who wanted to get back at supervisors who passed him over for promotion. At 15:55, the dispatcher returned with wind speeds, wind directions, and runway conditions at San Francisco and Los Angeles. Mechanical stops attached to the jackscrew prevent the stabilizer from moving farther than 2.5 degrees upward or 12.5 degrees downward. More importantly, investigators felt that the pilots should not have attempted to troubleshoot the problem after exhausting the procedures in the checklist, considering that they didnt know the extent of the damage. On board the stricken MD-83, the pilots managed to slow the dive somewhat, pulling up from 70 degrees nose down to 28 degrees, but the plane remained inverted, falling upside down toward the rapidly approaching ocean at a high rate of speed. Based on the airlines utilization rate at that time, this equated to 6,400 flight hours between inspections. [12], At least 35 occupants of Flight 261 were connected in some manner with Alaska Airlines or its sister carrier Horizon Air, including 12 actual employees,[13] leading many of the airline's personnel to mourn for those lost in the crash. In hindsight, the crew should have turned around and immediately landed back in Puerto Vallarta. For the relatives of the victims, this fact made it all the more important that Alaska Airlines pay for its negligence. I had to wait as the priorities for recovery were the victims, the flight recorders, and then the tail. Season 1 Episode 5 Alaska Airlines Flight 261, a McDonnell Douglas MD-83 aircraft, experienced a fatal accident on January 31, 2000 over the Pacific Ocean. [32][33], Captain Thompson and First Officer Tansky were both posthumously awarded the Air Line Pilots Association Gold Medal for Heroism, in recognition of their actions during the emergency. And so began a slash-and-burn cost-cutting campaign a campaign that culminated in a terrible black mark which will forever hang over the company, a tragedy so horrible and so preventable that it would call the safety of the entire industry into question. But over the next two decades, Alaska Airlines pursued an aggressive strategy of expansion, aiming to become an affordable option for travelers throughout the Western United States. Okay, give me sl see, this is a bitch! said Thompson. The tests also simulated the acme nut wear process by using blocks milled from a scrap acme nut and rings turned from a jackscrew forging. But we will be going into LAX, and Id anticipate us parking there in about twenty to thirty minutes.. The jackscrew is one of the few components of the MD-80 series that does not have a redundant backup in case of failure. I think its at the stop, full stop, said Thompson. The last minutes of those on board the doomed MD-83 would have been sheer hell, as the plane went inverted, corkscrewed, pirouetted, and spun like a top during its final dive. Fuck me, he said. The thread failure was caused by excessive wear resulting from Alaska Airlines' insufficient lubrication of the jackscrew assembly." The report noted that the crash could have been avoided if they had immediately returned to Puerto Vallarta when they encountered the jammed stabilizer. alaska airlines flight 261 pilot drunk. Fuck me!. I dont know, my adrenalines going, said Thompson. It got worse, okay. Violent vibrations shook the airplane. gakirah barnes death video; Financial Planning. There was nothing that Tansky and Thompson could have done to control the airplane. A few months after the accident, Alaska Airlines pointed the finger at Boeing for not only its single point failure jackscrew design, but also for the grease that Boeing tacitly approved. As flight 261 climbed through 23,400 feet at approximately 13:49 that day, the badly worn threads started to tear away from the nut, wrapping themselves around the jackscrew and causing the stabilizer to jam. Flight 261 was traveling from Puerto Vallarta to San Francisco on Jan. 31, 2000 when a mechanical malfunction inverted the jet and sent it downward off the Ventura County coast. [6], Using side-scan sonar, remotely operated vehicles, and a commercial fishing trawler, workers recovered about 85% of the fuselage (including the tail section) and a majority of the wing components. Not that I want to go on about it you know, it just blows me away they think were gonna land, theyre gonna fix it, now theyre worried about the flow. During the course of the investigation, and later in its final report, the NTSB issued 24 safety recommendations, covering maintenance, regulatory oversight, and aircraft design issues. [31] The sundial casts a shadow on a memorial plaque at 16:22 each January 31. Language links are at the top of the page across from the title. As such, it is critically important that the jackscrew be kept in good working order, primarily through the liberal application of grease at regular intervals. In fact, by now there were several other airplanes in the area that were keenly watching the unfolding situation. Two electric motors spin the jackscrew within the nut, causing the stabilizer to move up or down. [27], In 1998, an Alaska Airlines mechanic named John Liotine, who worked in the Alaska Airlines maintenance center in Oakland, California, told the FAA that supervisors were approving records of maintenance that they were not allowed to approve or that indicated work had been completed when, in fact, it had not. Instead it went the other way., What do you think. I dont think we should, if it can fly, its like . In September 2000, he filed a $20 million libel lawsuit against Alaska Airlines, arguing that he had been right all along and that Alaska had maliciously harmed his reputation. Push push push, push the blue side up!, Okay, now lets kick rudder, left rudder, left rudder. Just do what you need to do there, SkyWest 5154.

Only by applying a continuous maximum nose up elevator input on his control column, a task which required enormous physical effort, was Captain Thompson able to maintain level flight. The pilots, 53-year-old Captain Ted Thompson and 57-year-old First Officer Bill Tansky, could not have known that they were about to play out the final chapter in a sordid story that had been building toward its conclusion for years. Armed with knowledge of the end play check and the discovery of the slinky the FAA issued an emergency directive for all MD-80 operators to inspect their jackscrews and report any findings.

Individual maintenance tasks (such as the end-play check) were not separately considered in this extension. The Price of an Hour: The crash of Alaska Airlines flight 261 | by Admiral Cloudberg | Medium Write Sign In 500 Apologies, but something went wrong on our end. The original interval was 500 flight hours (graphic 12). "[6], Despite the attempt to fly the plane inverted, which almost entirely arrested its descent, the aircraft had lost too much altitude in the dive and was far beyond recovery. [6], End-play checks were conducted during a periodic comprehensive airframe overhaul process called a "Ccheck". He's, ah, down. Folks, we have had a flight-control problem up front here, first officer Ted Thompson told the passengers over the PA system. In addition to the probable cause, the NTSB found these contributing factors:[6] It might be mechanical damage too. [38] Many residents of Seattle had been deeply affected by the disaster. Both Captain Thompson and First Officer Tansky posthumously received the Air Line Pilots Association Gold Medal for Heroism. Less than one second later, Alaska Airlines flight 261 slammed into the Pacific Ocean, obliterating the aircraft and instantly killing all 88 people on board. The longer it went without being greased properly, the faster the jackscrew wore down the threads on the nut. Join the discussion of this article on Reddit! Im thinking, can it get any worse, but it probably can, he continued. Were slowing here, and were gonna do a little troubleshooting, can you give me a block altitude between twenty and twenty five?. Alaska Airlines' maintenance and inspection of its horizontal stabilizer activation system were poorly conceived and woefully executed. The whole episode must have left him a bitter man although unlike most whistleblowers, he did manage to restart his career in the industry. Over the course of a year I dragged the Systems Group all over the country to observe different maintenance shops perform jackscrew lubrications and end-play checks. Both of these circumstances resulted from Alaska Airlines' attempts to cut costs. [6], A special inspection conducted by the NTSB in April 2000 of Alaska Airlines uncovered widespread significant deficiencies that "the FAA should have uncovered earlier". In NTSB board member John J. Goglia's statement for the final report, with which the other three board members concurred, he wrote: This is a maintenance accident. Laboratory tests indicated that the excessive wear of the jackscrew assembly could not have accumulated in just the four-month period between the September 1999 maintenance and the accident flight. Following the crash, families successfully lobbied for design changes and improved airplane maintenance requirements. It broke off nine minutes later, allowing the jackscrew and its attached stabilizer to slide up and out of the acme nut causing the fatal dive. Pilots Thompson and Tansky disconnected the autopilot to see what they were up against, and found that the stabilizer had jammed slightly nose down, requiring constant force on the elevators to overcome it and continue climbing. The 2 pilots, 3 cabin crewmembers, and 83 passengers on board were killed, and the airplane was destroyed by impact forces. Despite Alaska Airlines numerous regulatory violations, the investigation ended in 2003 without any charges being filed. Saudi Arabian Airlines Flight 763/Kazakhstan Airlines Flight 1907 Crash Documentary - Sigh. By this point the amount of force he needed to apply to the control column to keep the nose level was pushing him to the limit of his physical ability. Refresh the page, check. The movement, or end play, between the gap of the acme nut and jackscrew threads is measured with a dial indicator and read in thousandths of an inch (see image 8). On January 31, 2000, Alaska Airlines Flight 261, bound for Seattle, plunges into the Pacific Ocean 40 miles northwest of Los Angeles, off the coast of California, killing all 88 passengers and crew. Ah, here we go, said Captain Thompson, uttering the last words captured on the cockpit voice recorder. An Alaska Airlines pilot, involved in the investigation of the horrific crash of Alaska Flight 261, has listened to the cockpit voice recorder from the downed plane and he reported that for the . He opened the mic for the public address system but never managed to get any words out. The problem was that with insufficient grease, the threads on the nut began to wear down at an accelerated rate. [6], The jackscrew assembly was designed with two independent threads, each of which was strong enough to withstand the forces placed on it. I went tab down, right, and it should have come back. Oh yeah, let me get said Tansky. And so it was that on a sunny day in January 2000, 83 passengers and five crew boarded Alaska Airlines flight 261 in the resort city of Puerto Vallarta, Mexico, bound for San Francisco, California. Did maintenance errors. [39] Students and faculty at the John Hay Elementary School in Queen Anne, Seattle, held a memorial for four Hay students who were killed in the crash. A flight attendant opened the cockpit door, and Captain Thompson briefed her on the situation. [35], Both McDonnell Douglas and Alaska Airlines eventually accepted liability for the crash, and all but one of the lawsuits brought by surviving family members were settled out of court before going to trial. [6], Between 1985 and 1996, Alaska Airlines progressively increased the period between both jackscrew lubrication and end-play checks, with the approval of the Federal Aviation Administration (FAA). [6], Due to the extreme impact forces, only a few bodies were found intact,[5] and none were visually identifiable. The data indicated that the airplane climbed normally until 23,400 feet, where the horizontal stabilizer trim system stopped moving, the autopilot disconnected and the climb rate slowed. [6] Both pilots had previous military experience Thompson in the U.S. Air Force and Tansky in the U.S. The acme nut was constructed from a softer copper alloy containing aluminum, nickel, and bronze. Some did still less, failing even to ensure that grease totally filled the inside of the nut. Kyra Dempsey, analyzer of plane crashes. What I want to do is get the nose up, and then let the nose fall through and see if we can stab it when its unloaded. It was his belief that the stabilizer might move nose up if there was no aerodynamic force pushing it upward into the nose down position. Both the horizontal stabilizer trim system jackscrew (also referred to as "acme screw") and the corresponding acme nut, through which the jackscrew turns, were found. The effect was immediate and catastrophic, as his inputs ripped out whatever threads remained on the jackscrew nut. [6] The captain replied: "I need to get down to about ten, change my configuration, make sure I can control the jet and I'd like to do that out here over the bay if I may. At 16:07, flight 261 contacted Alaska Airlines Los Angeles maintenance facility on the radio. And then, as the plane passed through 23,400 feet, a warning light flicked on in the cockpit: AUTOPILOT TRIM, it said. [15], Alaska Airlines Flight 261 departed from Puerto Vallarta's Licenciado Gustavo Daz Ordaz International Airport at 13:37 PST (21:37 UTC), and climbed to its intended cruising altitude of flight level310 (31,000 feet or 9,400m). An engineering fix developed by engineers of NASA and United Space Alliance promises to make progressive failures easy to see and thus complete failures of a jackscrew less likely. A new jackscrew has a gap less than 0.010-inch. [30], The victims' families approved the construction of a memorial sundial, designed by Santa Barbara artist James "Bud" Bottoms, which was placed at Port Hueneme on the California coast. However, only the specimens with no grease mirrored the severe wear rate of the accident airplane. In December of 1998 the federal government launched a criminal investigation into Alaska Airlines, seizing documents and interviewing witnesses. We also noted that accessing the area for the lubrication was unwieldy, especially on a tail stand at night (images 10 & 11). [6], Beginning at 16:19 (00:19 UTC), the CVR recorded the sounds of at least four distinct "thumps", followed 17 seconds later by an "extremely loud noise", as the overstrained jackscrew assembly failed completely and the jackscrew separated from the acme nut holding it in place. This three-dimensional animated accident reconstruction shows the final pitch-over and initial portion of the dive for Alaska Airlines Flight 261, which cras. Were going to LAX, Thompson told the dispatcher. We went to full nose down and Im afraid to try it again to see if we can get it to go in the other direction.. In August 1999, Alaska Airlines put Liotine on paid leave,[28] and in 2000, Liotine filed a libel suit against the airline. Speedbrakes! Captain Thompson called out, still trying to find ways to arrest the dive. The accident served as an inspiration for the fictionalized crash landing depicted in the 2012 movie Flight starring Denzel Washington. Okay, we had a big bang back there, said the flight attendant. As Thompson fought with all his might to regain control, Tansky shouted Mayday! but forgot to key his mic. It was found that the use of Aeroshell 33 was not a factor in this accident. Hands clenching my headphones, I listened to the crew talk among themselves, with airline dispatch and to air traffic controllers in an attempt to keep the airplane kinda stabilized as they put it. Investigators later uncovered a critical maintenance. An airliner cannot truly fly upside down maintaining level flight in such a condition is essentially impossible, and the engines will quickly die but if anyone ever came close, it was Captain Thompson and First Officer Tansky as they heroically tried to save their stricken aircraft, even after all hope was lost. A chunk of the vertical fin was brought up next. But maintenance, poorly done, will find a way to bite somewhere else. Eighty-eight people nearly half of them airline employees and some of their families on vacation had lost their lives along with Tansky, Thompson and three flight attendants. The criminal investigation also proved to be a disappointment. The mechanic went to federal authorities in late 1998 claiming the airline was cutting back on maintenance and falsifying records to get planes back into operation faster.

The aircraft was the 1995th DC-9/MD80 family airframe built,[2] was manufactured and delivered new to Alaska Airlines in 1992, and had logged 26,584 flight hours and 14,315 cycles before the crash. You want to try it or not?, Keying the public address system, Captain Thompson announced, Folks, we have had a flight control problem up front here; were working it Uh, thats Los Angeles off to the right there, thats where were intending to go.
