Pilots had reported pressurisation warnings on three earlier flights by the plane involved in a mid-air blowout, investigators have said.
Alaska Airlines was forced to perform an emergency landing on Friday after a door plug was torn offof the Boeing 737 MAX 9 plane flying 171 passengers from Portland in Oregon, to Ontario in California.
The incident happened after the auto-pressurisation fail light lit up on the same aircraft on 7 December last year and 3 and 4 January this year.
After those warnings, the airline chose to ban the aircraft from making long flights over water to Hawaii, in case it needed to turn back to an airport, the National Transportation Safety Board (NTSB) said.
But it is unclear if there is any connection between those incidents and the accident, NTSB chair Jennifer Homendy said.

‘We are very, very fortunate’
She also described a harrowing picture of the incident, with the 27kg part blown off the side of the aircraft, causing rapid depressurisation inside the plane, which had not reached cruising altitude.
The force of the decompression led to the cockpit door being blown open while the flight crew could not communicate with the pilots.
“They heard a bang,” Ms Homendy said of the flight crew, adding a quick-reference laminated checklist was sucked out of the hole, while the first officer lost her headset.

“Communication was a serious issue… it was described as chaos.”
The door plug – which filled the space where the hole was made – has now been recovered by a school teacher only named as Bob from Cedar Hills in Portland.
Door plugs are components that can fill plane doorways that are unused by airlines.

There were also four unaccompanied minors on the flight, Ms Homendy said, with “heroic” flight attendants ensuring they had their oxygen masks on.
Missing voice recorder data
To compound communication issues, the cockpit voice recorder (CVR) had no data as it was not retrieved within two hours, when recording restarts and previous data is erased.
“It’s a very chaotic event, the circuit breaker for the CVR was not pulled, the maintenance team went out to get it, but it was right at about the two-hour mark,” Ms Homendy said.
“If that communication is not recorded, that is unfortunately a loss for us… that information is key not just for our investigation but for improving aviation safety.”
In response to the mid-air incident, the US Federal Aviation Administration (FAA) grounded 171 Boeing 737 MAX 9 planes to run inspections, which has caused cancellations to pile up for passengers. Other 737 MAX 9s have been grounded elsewhere.
Alaska Airlines said it cancelled 170 flights on Sunday and a further 60 on Monday, with more expected this week and other airlines also affected.
Reports were ‘fully evaluated’
Responding to the reports on the warning lights, Alaska Airlines said aircraft pressurisation system write-ups are typical in commercial aviation operations with large planes.
“In every case, the write up was fully evaluated and resolved per approved maintenance procedures and in full compliance with all applicable FAA regulations,” the airline said.
Ms Homendy had previously said it was “very lucky” the accident wasn’t far worse.
She revealed no one was sat in the seats immediately next to the affected part of the fuselage – and because the plane had not reached cruising altitude, passengers and crew were not moving around the cabin.
No one was injured, and the plane landed safely back in Portland.
Boeing stock dropped more than 8% in premarket trading on Monday following the groundings.
The major backer of Pinewood Studios is among the suitors vying to buy Village Hotels, one of Britain’s biggest mid-market hotel chains.
Sky News understands Aermont, which specialises in real estate-backed investments, submitted an offer last week for Village Hotels, which is owned by KSL Capital Partners.
City sources said KSL was seeking offers worth in the region of £850m or more.
A number of other parties are also understood to have tabled bids ahead of a deadline last week.
Blackstone, the giant private equity firm, is considering making an offer but has yet to do so, according to insiders.
Henry Birch, the former boss of Rank Group, is among the candidates vying to run Entain, the FTSE-100 owner of Ladbrokes.
Sky News has learnt that Mr Birch is one of a small number of candidates being considered by Entain to replace Jette Nygaard-Andersen as its permanent chief executive.
The recruitment process comes at a challenging time for Entain, which has been beset by boardroom upheaval and regulatory difficulties in various international markets.
Its stock has halved in the last year, leaving it with a market capitalisation of just under £5bn.
This weekend, sources close to the company confirmed that Mr Birch was a serious contender for the post, although they said others were also in contention.
An appointment could still be weeks or even a small number of months away, they added.
Mr Birch stepped down as chief executive of Very Group, the online retailer owned by the Barclay family, in 2022.

He is an experienced gambling industry executive, having spent four years as chief executive of William Hill Online prior to joining the London-listed multichannel gaming operator Rank Group.
He has also held roles at Leisure & Gaming plc and BettingCorp.

Under Mr Birch, Very Group broke the £2bn annual sales mark for the first time.
Investors in Entain have been pressing its board to recruit a new chief executive with substantial gambling experience as it grapples with a plunging share price and numerous regulatory and strategic challenges.
Industry sources said that Dan Taylor, chief executive of Flutter Entertainment’s international operations, had also been approached, although it was unclear whether he was interested.
Entain has been under siege from activist investors for months.
In January, it announced that Ricky Sandler, who runs Entain shareholder Eminence Capital, would join its board as a non-executive director.
Last month, it said that Barry Gibson, its chairman, would retire later this year and be replaced by interim chair, and former acting CEO, Stella David.
Entain has hired bankers to sell PartyPoker and other non-core operations, which the Financial Times reported could include Netherlands-based BetCity, which Entain bought for £398mn last year.
As well as Ladbrokes, Entain owns Coral and a stake in BetMGM, a major US betting player.
MGM Resorts, the US casino operator behind the Bellagio in Las Vegas, attempted to buy Entain in 2021 but was rebuffed at a much higher valuation than the UK company’s shares trade at now.
A privately owned used-car platform is circling Cazoo Group, its stricken US-listed rival which is on the brink of administration.
Sky News has learnt that Motors.co.uk is a leading contender to acquire Cazoo’s marketplace operation, which would include its brand and intellectual property assets.
The process to auction the used-car platform’s constituent parts comes after it spent tens of millions of pounds on sponsorship deals in football, snooker and darts in a rapid attempt to gain market share.
Earlier this week, Cazoo filed a notice of intention to appoint Teneo as administrator, just three years after it floated in New York with a valuation of $8bn.
The filing was intended to provide protection from creditors while Teneo finalises asset sales.
Since an announcement last month about a restructuring of the group, advisers have offloaded a string of assets and unwound Cazoo’s previous operating model to transform it into a marketplace.
Among those have been the disposal of Cazoo’s vehicle fleet, which sources said had been achieved at higher-than-anticipated values, reflecting a current shortage of used cars in the market.
Teneo is also said to have struck a deal with Constellation Automotive, the owner of Cazoo’s rival, Cinch, involving a handful of sites and dozens of jobs.
Meanwhile, several parties are understood to have expressed an interest in Cazoo’s wholesale operation and other vehicle collection sites.

One industry source said the pivot to a platform model had seen its inventory rise to more than 15,000 cars, with Cazoo now the online vehicle marketplace where consumers can buy and sell cars under a single brand.
If, as expected, the group does fall into administration, it would underline the rapid implosion of a company which once ranked among Britain’s hottest technology start-ups.
Founded by Alex Chesterman, the founder of Zoopla, it raised hundreds of millions of pounds in funding, and rapidly attracted a ‘unicorn’ – or $1bn – valuation.
Mr Chesterman left the business several months ago in the wake of a balance sheet restructuring which saw hundreds of millions of dollars of debt converted to equity.
One insider said the formal triggering of insolvency proceedings was likely to attract wider attention in Cazoo’s assets, including its brand.
It was unclear on Friday how much Motors.co.uk or other suitors for the marketplace were likely to bid for it.
A spokesperson for Cazoo said: “Our new marketplace model, where consumers can both buy and sell cars, is revenue generating and performing ahead of expectations with interest from almost 100 car dealers including many household names wishing to trade on the Cazoo platform.
“Cazoo has successfully restructured and significantly reduced the cash burn of the group, resulting in a cash position in excess of £95m at 30th April 2024 compared to £113m at 31st December 2023, and the platform now has approximately 17,000 cars which is more than double the volume we previously supported and demonstrates the scalability of our technology and the strength of the team.
“We are making efforts to secure the next phase of our business and are grateful to our employees for their hard work and commitment.”
Motors.co.uk did not respond to enquiries, while a spokesperson for Cazoo declined to comment on talks about asset sales.
