The FAA probe, which could result in a financial penalty on Boeing, marks an escalation by the agency over the incident.
The US Federal Aviation Administration (FAA) is launching a formal investigation into aircraft manufacturer Boeing after a cabin panel blowout on an Alaska Airlines-operated 737 Max 9 jet last week forced an emergency landing.
“This incident should have never happened and it cannot happen again,” the FAA said in a statement on Thursday, after a panel known as a “door plug” blew out of the plane, causing a gaping hole, shortly after takeoff from the western US state of Oregon.
There were no fatalities or serious injuries after Alaska Airlines safely executed an emergency landing in the January 5 incident, but investigators with the National Transportation Safety Board (NTSB) have said the incident could have resulted in serious harm.

The FAA probe – which could result in a financial penalty on Boeing – marks an escalation by the agency following the first major in-flight safety issue on a Boeing plane since the fatal 2018 and 2019 737 Max crashes that killed 346 people and led to all aircraft being grounded for nearly two years.
The FAA also said it was investigating “additional discrepancies on other Boeing 737-9 airplanes,” according to a letter to the company that gave it 10 days to respond.
This refers to reports from Alaska and United Airlines of “loose” hardware on delivered planes found in preliminary investigations of the jets.
“Boeing’s manufacturing practices need to comply with the high safety standards they’re legally accountable to meet,” the FAA said.
The letter cited a statute requiring Boeing to ensure that “completed products” are “in a condition for safe operation.”

The agency said Boeing’s response to the FAA should include the “root cause” of the incident, actions to prevent a recurrence and any relevant mitigating circumstances.
Boeing said on Thursday that it would “cooperate fully and transparently” with the investigations.
Aviation consultant Jeff Guzzetti, a former head of the FAA’s investigation division who also worked at the NTSB, said the “sweeping” language in the FAA letter suggests the investigation could be broadened to Boeing’s production processes, including into other planes besides the Max.
Boeing will need to spell out its investigative findings, even if it has not determined a root cause, Guzzetti told the AFP news agency, adding that the probe could take months and result in fines.
Guzzetti said he is hoping that the Alaska Airlines problem was a “one-off” but “if it turns out to be many aircraft, that will be disturbing to me”.

‘Fact-finding continues’
US regulators have grounded 171 737 Max 9 planes with the same configuration as the jet involved in the incident this month.
Earlier this week, Boeing CEO Dave Calhoun promised “complete transparency” as the aviation giant tries to pivot from its latest crisis.
In an interview with US broadcaster CNBC on Wednesday, Calhoun said the company was still in fact-finding mode, adding that “we’re going to want to know what broke down in our gauntlet of inspections”.
The affected panel is used to fill spots for extra doors when those exits are not required for safety reasons, and NTSB investigators have suggested that the part was not affixed adequately.
The FAA has been working with Boeing on inspection instructions for the 737 Max 9 planes before they can be returned to service.

Alaska Airlines has cancelled flights on the aircraft through January 13, resulting in between 110 and 150 flight cancellations per day.
A Seattle law firm on Friday filed a class-action lawsuit against Boeing, saying passengers on the Alaska Airlines flight suffered physical and psychological injury and emotional distress. It seeks unspecified damages for the treatment of health conditions, travel expenses and the loss of personal items.

This June, two very different offers reach Alaska families, and both amount to the same thing: $10,000. The difference is everything.
Bill Walker, running for governor, would hand every eligible Alaskan a one-time $10,000 check and then end the Permanent Fund dividend for good. Ask one question: Where does his $10,000 come from?
It comes from the Permanent Fund, the people’s own money and the savings Alaskans built for their children. Walker would spend that endowment once to pay Alaskans to give up the yearly dividend forever.
Think about what that does. It cancels the annual check that gives a family a reason to keep an Alaska address and replaces it with a single payout. You hand people their own savings, call it a gift and cut the tie that held them here in the same motion. It is the oldest mistake in governing money: raid what you have saved to buy a moment’s applause and call the spending generosity.

A plan that spends the people’s savings to send the people away is not bold. It is foolish.
Now consider the other $10,000. Through Alaska Housing Finance Corp., the state offers families up to $10,000 to build a new, energy-efficient home. AHFC raids nothing. It earns its own way. Over the years, it has returned more than $2 billion to the state treasury, and it spends some of that income the way any good business does: to win a customer.
Here, the customer is an Alaskan who wants to own a home, put down roots and stay.
That is the oldest sound move in business: Invest a little of what you earn to bring in someone who stays. The homeowner remains, the community gains a family and the corporation keeps earning. The money spent comes back. A plan that puts earnings to work to bring people home is not charity. It is clever.
Same amount. Opposite source. Opposite wisdom. One spends savings; the other spends earnings. One pays Alaskans to leave; the other pays them to stay. One empties the state; the other fills it.

This Homeownership Month, the choice is the size of a single check, and the whole question is where the check comes from and what it asks of you. Ten thousand dollars of your own fund, to wave you goodbye. Or $10,000, earned and reinvested, to help you stay and build.

A man with the same name and party affiliation as Alaska Republican U.S. Sen. Dan Sullivan is eligible to challenge the senator in the August primary, a judge ruled Friday.
Superior Court Judge Thomas Matthews’ ruling overturns a June 15 decision by Division of Elections Director Carol Beecher to disqualify the challenger and keep him off the primary ballot. Matthews’ ruling can be appealed to the state Supreme Court.
Attorneys for the state have said Tuesday is the deadline for a final ruling so that ballots for the Aug. 18 primary can be printed.
The judge ruled that the division’s decision to exclude Dan J. Sullivan because his candidacy was not “in good faith” was not based on the Constitution, Alaska law or the division’s own regulations. The retired teacher from the small fishing community of Petersburg filed to challenge the incumbent.

“Instead, the decision was based upon a new, previously unstated, ‘good faith’ criteria,” the judge wrote.
The division is appealing the decision, Sam Curtis, a spokesperson with the state Department of Law, said by email Saturday. Jeffrey Robinson, an attorney for Dan J. Sullivan, said in an email he expected the division to appeal and couldn’t comment until the Alaska Supreme Court rules on the case.

The controversy over the two Dan Sullivans has underscored the stakes involved in the incumbent’s reelection campaign. The Alaska race is one of about half a dozen U.S. Senate races expected to be highly competitive in the fall, and the seat is one Democrats are trying to flip in their efforts to try to regain the majority. But it’s expected to be an uphill battle in a state that President Trump won by 13 points in 2024.
The senator and allies, including the National Republican Senatorial Committee, have condemned the challenger’s efforts to join the race, arguing his presence could confuse voters. Republican Lt. Gov. Nancy Dahlstrom earlier this month opened an investigation into the non-Senator Sullivan’s candidacy.
Under Alaska’s election system, the top four candidates from the primary, regardless of party, move on to the ranked-choice November general election.
The senator has accused the challenger Sullivan of working with Democrats and the campaign of Democratic former U.S. Rep. Mary Peltola — who is considered the senator’s main opponent — to cause confusion and boost Peltola’s chances. The sitting senator brought the situation to reporters’ attention at the Capitol earlier this month, accusing Democrats of being “complicit in trying to trick Alaskans” to “rig an election in their favor.”

Peltola’s campaign and state Democrats have denied the allegation, as has the challenger.
Sen. Sullivan and Peltola are the highest-profile candidates in the crowded race and the only ones to report raising any money.
Beecher has said she determined the challenger Sullivan is not eligible to run because his candidacy was not filed in good faith and instead was done with an intent to confuse voters. She said he had registered to vote as Daniel J. Sullivan Jr. and, in conjunction with his candidacy, changed his party affiliation to Republican. She also cited similarities between his campaign website and the senator’s, and his work with a consultant whose clients have included some Democrats. She did not mention finding any evidence of alleged coordination.
In arguing to keep the challenger disqualified, attorneys for the state pushed back on suggestions the ballot could be designed in a way to reduce voter confusion over two candidates with the same name and party running for the same office.

“The Constitution does not require States to place a sham candidate on the ballot and then attempt to mitigate the damage through design choices,” attorney Rachel Witty, with the Alaska Department of Law, and outside attorneys Christopher Murray and Michael Francisco wrote in court filings.
Attorneys for the challenger Sullivan argued that the Constitution lays out three exclusive qualifications for the Senate, addressing only age, citizenship and residency. They said Beecher lacked the legal authority to boot their client off the ballot.
The challenger Sullivan has said that sharing a name and party affiliation with the incumbent gave him “an instant megaphone.” But the 69-year-old retired teacher and former U.S. Forest Service employee said he had considered a run for some time and had grown frustrated with the senator.
He initially was certified on the state’s candidate list as Dan J. Sullivan, with the senator listed as Dan S. Sullivan and identified as the incumbent.
