The problems began almost immediately this year when, on January 5, Alaska Airlines Flight 1282 lost a door plug midair, blowing a hole in the side of the plane. While no one died in the incident, several passengers were injured, and the pilots were forced to make an emergency landing in Portland, Oregon.

In the aftermath of the incident, the FAA temporarily grounded over 170 of Boeing's 737 Max 9 planes until they could complete safety inspections.

The Justice Department opened an investigation into Boeing shortly after, and the FBI told passengers aboard the flight that they might have been victims of a crime.

Boeing was hit with multiple lawsuits this year.

Passengers from the Alaska Airlines flight filed a class action suit against the company just days after the incident.

"Passengers were shocked and confused, thrust into a waking nightmare unsure if these were their last seconds alive," the lawsuit said.

Boeing's shareholders filed a separate class action suit against the company in January, stating that it had prioritized profit over safety, Reuters reported.

Separately, in July, Boeing struck a plea deal related to two 737 Max crashes in 2018 and 2019 that killed 346 people. If a judge had approved the deal, it would have allowed Boeing to plead guilty to conspiracy to commit fraud, avoid a trial, pay a fine of about $244 million, and invest at least $455 million in safety and compliance measures.

Boeing agreed to pay $2.5 billion in 2021 in a deal with the federal government to avoid prosecution for the crashes, but Justice Department officials said in May that Boeing had violated portions of the deal, putting a trial back on the table. Relatives of the deceased passengers asked a Texas judge in October to throw out the agreement, which they called a "sweetheart" deal. The families have previously called for the company to pay a fine amounting to nearly $25 billion.

In December, the judge rejected the deal. A lawyer representing families who lost people in the 2019 crash told BI that they "anticipate a significant renegotiation of the plea deal that incorporates terms truly commensurate with the gravity of Boeing's crimes."

The Federal Aviation Administration commissioned a report into Boeing following the fatal 2018 and 2019 crashes — and the results published in February weren't good news for the company.

The FAA report found 27 insufficient areas in Boeing's safety procedures, including no clear system for employees to report safety concerns, confusing management structures, and poor communication with employees about safety procedures.

The latest statement from the FAA about Boeing's compliance to remedy the safety issues was published in August. It said the agency continues "actively monitoring Boeing's progress in a variety of ways," including regular reviews by FAA experts of Boeing's safety procedures and issuing airworthiness certificates for every newly produced Boeing 737 Max. 

The FAA itself has faced scrutiny for its oversight of Boeing. A report from the Department of Transportation's Office of the Inspector General in October found the agency's checks were insufficient.

In March, Boeing announced a leadership shake-up.

CEO Dan Calhoun said he would step down. Stan Deal, the CEO of the company's commercial airplanes division, said he would retire. In the same announcement, board chair Larry Kellner announced his plan not to seek reelection.

Stephanie Pope, the company's COO, was promoted to replace Deal shortly after his departure. At the end of July, Kelly Ortberg was named the company's new CEO.

Ted Colbert, who headed Boeing's defense, space, and security division, became the first prominent executive to leave the company after Ortberg took over. Colbert's departure was announced in September.

The aerospace company faced another high-profile problem in June when NASA astronauts Butch Wilmore and Suni Williams traveled to the International Space Station on Boeing's CST-100 Starliner spaceship. It marked the first time Boeing flew astronauts to space.

The astronauts left Earth on June 5 and were supposed to return after eight days, but issues with Starliner's thrusters and helium leaks caused delays. NASA and Boeing began troubleshooting the problems to bring Wilmore and Williams back home. However, in late July, the two astronauts were still stuck at the International Space Station.

NASA's Commercial Crew Program manager, Steve Stich, said in a press briefing that month that Elon Musk's SpaceX could bring home the astronauts if needed. After working with Boeing to determine whether the two astronauts could safely return to Earth on Starliner, NASA announced in August that it chose SpaceX to do the job instead.

"Spaceflight is risky," NASA Administrator Bill Nelson said during a press conference. "Even at its safest. Even at its most routine. A test flight, by nature, is neither safe nor routine. So, the decision to keep Butch and Suni aboard the International Space Station, and bring the Boeing Starliner home un-crewed, is a result of a commitment to safety."

The decision was a major blow to Boeing, which spent $4.2 billion developing Starliner. Wilmore and Williams' flight was the final step Boeing needed to clear for NASA to certify Starliner for human spaceflight. It highlighted just how far Boeing lags behind its competitor, SpaceX.

Wilmore and Williams are now expected to return to Earth in 2025 on SpaceX's Crew Dragon spaceship, which launched for the International Space Station in September. The astronauts were initially set to return home in February, but NASA announced they would be delayed until March as SpaceX readies its spaceship.

Thousands of unionized Boeing employees walked out in September after contract negotiations broke down.

The strike began despite a promising pay package proposal, which would have raised wages by more than 25% over the contract period for more than 32,000 employees in the Pacific Northwest.

Ultimately, union workers denied the proposal and voted to initiate a strike, which is costing the company about $50 million a day.

Negotiations stalled, with both sides filing National Labor Relations Board violations accusing the other of negotiating in bad faith.

Boeing and union leaders reached a tentative deal on October 19 that included a 35% general wage increase spread over four years and a one-time ratification bonus of $7,000.

However, striking Boeing employees rejected the deal on October 24.

"After 10 years of sacrifice, we still have ground to make up. We hope to resume negotiations promptly," the International Association of Machinists and Aerospace Workers said on X.

The 53-day strike ended in early November when workers approved a new contract.

Boeing began furloughs of white-collar workers in mid-September after the strike began. Select employees were required to take one week off every four weeks on a rolling basis.

Ortberg, in a staff memo, also announced that executive leadership would take a "commensurate pay reduction for the duration of the strike," though details of the pay reduction remain unclear.

Layoffs began several weeks later. In mid-October, Boeing announced plans to lay off about 10% of its 170,000-member workforce.

In a memo to employees, Ortberg said Boeing was in a "difficult position" and that "restoring our company requires tough decisions."

The company also delayed production of its 777X twin-engine jet and discontinued production of its 767 cargo plane, the memo noted.

The experimental 777X is Boeing's newest widebody plane, banking 481 orders from more than a dozen global carriers even though regulators have not yet approved it to fly passengers.

But the aircraft has been riddled with production problems — like supply chain issues, design troubles, and now the ongoing strike — which have already put it five years behind schedule and set Boeing back $1.5 billion.

That hole will likely deepen with the latest entry delay to 2026, further eroding the industry's trust in Boeing's 777X program. It could also push carriers to choose Boeing's European rival Airbus and its already-in-service Airbus A350.

The aircraft is still uncertified but started certification flight testing in July. Testing was halted in August due to a problem with a key part that connects the engine to the aircraft, CNBC reported.

The FAA announced in January that it would not grant any production expansions of Boeing's MAX aircraft, including the 737 MAX 9, following the emergency on Alaska Airlines Flight 1282.

"The Jan. 5 Boeing 737-9 MAX incident must never happen again," the FAA said in a press release said.

FAA Administrator Mike Whitaker said Boeing would not be cleared to expand production or add additional production lines for the 737 MAX "until we are satisfied that the quality control issues uncovered during this process are resolved," according to the press release.

Boeing held a three-hour meeting with the FAA in June to address safety and quality concerns. Afterward, Whitaker spoke at a press conference, where he told a reporter that expanding production of 737 MAX planes was still up in the air.

The FAA told Business Insider, "This is about systemic change, and there's a lot of work to be done. Boeing must meet milestones, and the timing of our decisions will be driven by their ability to do so."

The agency added: "Boeing has delivered a roadmap to change its safety culture, and the FAA will make sure Boeing implements the changes they have outlined. We will not approve production increases beyond the current cap until we're satisfied they've followed through on implementing corrective actions and transforming their safety culture."

Boeing restarted production of the 737 Max in December following the strike's conclusion.

Sam Salehpour, a Boeing engineer, testified at an April Senate hearing that the company ignored his reports on safety concerns, that his boss retaliated against him, and that he received threats against his physical safety.

The Senate subcommittee investigating Boeing's safety and quality practices released a 204-page report in June. The report included accounts from several whistleblowers.

Sam Mohawk, a Boeing quality assurance inspector, said the company lost track of hundreds of bad 737 parts and instructed employees to conceal improperly stored plane parts from FAA inspectors.

Another whistleblower, Richard Cuevas, wrote in a June complaint to the FAA that holes were being incorrectly drilled on Boeing's 787 Dreamliner planes.

In a sign of how Boeing's problems have hurt its bottom line, the company said in a regulatory filing to the SEC in October that it had entered a $10 billion credit agreement with four major banks: JPMorgan Chase, Goldman Sachs, Bank of America, and Citibank.

The company also filed a prospectus saying it might sell up to $25 billion in securities.

"These are two prudent steps to support the company's access to liquidity," Boeing said in a statement.

While workers were on strike, Bank of America analysts estimated that the work stoppage cost Boeing $50 million a day.

To save money, Ortberg, the company's CEO, instructed top executives to stop flying private jets and instead fly economy on commercial flights.
