The heroic actions from the Alaska Airlines Flight 1282 crew made sure that everyone survived last year when a door panel flew from the plane shortly after erection, leaving a gap hole that absorbed WTOs from the cabin, said the chairman of the national security board Jennifer Homomendy on Tuesday.
But Homendy said “the crew should not have been heroes because this accident should have never happened.” The Board revealed that the loss in the production and supervision of Boeing security, combined with ineffective inspections and audits by the federal aviation administration, led to terrible weakness.
The NTSB investigation over the past 17 months revealed that four bolts that provided what is known as the door plug panel were removed and never replaced during a repair while the Boeing 737 Max 9 was gathering.
The explosion happened a few minutes after the flight rose from Portland, Oregon and created a noisy air vacuum. Seven passengers and a flight doctor suffered minor injuries, but none of the 177 on board were killed. Pilots landed the plane probably again at the airport.
Boeing and Spirit Aerosystems – the company that made and installed the door plug – are redesigning them with another spare system to keep panels in the country even if bolts are missing, but this improvement is alive to be certified by FAA by 2026 at faster. NTSB asked companies and regulator to ensure that 737 Max has been retrained with those new panels.
Both Boeing and FAA have improved training and processes since the incident, according to NTSB, but board officials said the company and agency should better identify the risks of production and address them to make sure such flaws do not steal again.
Homendy only made Boeing’s new director, Kelly Ortberg, to improve security since he took over last summer, though she said she should do more.
NTSB recommended that Boeing continue to improve their own training and safety standard and ensure that everyone knows when the actions are documented. Board members also emphasized the need to ensure that everyone across the company understands its security plan as well as leaders.
The Board also asked the FAA to grow and ensure that its address and inspections of the address based on past problems and system issues. The agency was also encouraged Tuesday to evaluate Boeing’s security culture and reconsider its long policy so as not to demand that children under 2 travel to their countries with proper restrictions.
Many of the NTSB recommendations echo a report by the Inspector General of the Transport Department issued last year and that FAA is already working to implement.
FAA said in a state that “has changed radically how Boeing has been overseeing since the Alaska Airlines Die-Plug accident and we will continue this aggressive supervision to ensure that Boeing regulates its quality production issues. The company reviews its progress and any challenges it faces in implementing the necessary changes.”
In one country, Boeing said it will review the NTSB report after it continues to improve.
“We in Boeing regret this accident and continue to work to strengthen security and quality throughout our operations,” the company said.
Oxygen masks fell and phones went flying
The accident happened while the plane flew at 14.830 meters (4520 meters). Direct oxygen masks during rapid decompression and some other cells and objects were included through the hole in the plane while passengers and crew opposed the wind and noise.
The first six minutes of flight to Ontario International Southern California Airport were routine. The aircraft was about half the road to its cruise height and traveled in more than 400 km per h (640 km per h) when passengers described a loud “boom” and the smell so strong that removed the shirt from one’s back.
“We knew something was wrong,” Kelly Bartlett the Associated Press told the days after the flight. “We didn’t know what. We didn’t know how serious. We didn’t know if we would say we would fall.”
The 2-foot-up 4-foot fuselage (61-centered from 122) covering an unused emergency output behind the left arm was blown up. Only seven places in the flight were careless, including the two places closest to the opening.
NTSB J. Todd Inman said Alaska Airlines accident would have been worse if it had occurred over the ocean and far from the ground, but the carrier had already limited the plane used for flights 1282 to flights to the ground due to an unsolved maintenance issue with a fuel pump. The airline took that step on its own, going beyond the FAA demands, Inman said.
Missing bolts focus on Boeing production
The exploding panel was removed in a Boeing factory, so the works can repair five damaged rivets, but the bolts that help provide the door outlet were not replaced. It is not clear who removed the panel.
NTSB said in a preliminary report that four bolts were not replaced after repair work, but the work was not documented.
Investigators determined that the door was gradually going upward during 154 flights before the incident before finally flying.
Boeing factory works told NTSB investigators that they felt pressure to work very quickly and were asked to do jobs that they were not qualified away. None of the 24 people on the door team were ever trained to remove a door before working on the plane in question and one of them had previously had a before. That person was on vacation when it was done in this case.
No one from the door team was working when the plug was installed again.
Investigators said Boeing did not do enough to train younger workers who did not have a background in production. Many of them who were employed after the pandemic and two clashes involving the 737 maximum planes did not have that experience, and there were no clear standards for workplace training.
NTSB staff also told the board that Boeing did not have strong enough security practices to ensure that the door was properly reinstalled, and the FAA inspection system did not do a good job to capture system failures in production. Boeing was asked to approve a more rigorous group of security standards after a 2015 solution, but NTSB said the plan had been in place for just two years before the specific Alaska Airlines plane that suffered the door plug failure and that it was still.
FAA regularly develops more than 50 audits a year in Boeing production, but there are no clear standards for those that cover those audits. The agency routinely rejected the record record of the past after five years and does not always base its inspection plan on those past findings.
Problems with Boeing 737 Max
The maximum version of the Boeing’s best Bestselling 737 has been the source of constant problems for the company since two from Jets crawled, one in Indonesia in 2018 and another in Ethiopia in 2019, killing a 346 combined people.
Investigators determined that those clashes were caused by a system that religion in a sensor providing wrong readings to push the nose down, letting pilots unable to recover control. After the second crash, Max Jets was based around the world until the company redesigned the system.
Last month, the Department of Justice reached an agreement that allowed Boeing to avoid prosecution for allegedly fraudting US regulators for the maximum of two clashes.

Regulators in the Federal Aviation Administration have captured the production of Boeing 737 Max at 38 aircraft a month while investigators ensure that the company has strengthened its security practices, and the agency said there are no plans to remove that CAP plane. “
Boeing hired Ortberg last year and created a new position for a senior vice president of quality to help improvise its production.
The company was again in the news earlier this month when a 787 flew from Air India crawled shortly after the rise and killed at least 270 people. Investigators have not determined what caused that collision, but they did not find any flaws with the model, which has a strong security record.
This story reassesses the height of the aircraft to 14,830 meters from 16,000 meters based on NTSB updated information.
