New questions about the Boeing 737 Max after a plane heading to California suffers a gaping hole in its side

The emergency landing of a Boeing 737 Max jetliner with a gaping hole in its side and the airline’s decision to ground identical planes is renewing questions about the safety of Boeing’s best-selling plane — one that was involved in two deadly crashes.

The emergency landing of a California-bound Boeing 737 Max jetliner with a gaping hole in its side and the airline’s decision to ground identical planes is renewing questions about the safety of Boeing’s best-selling plane — one that was involved in two deadly crashes.

A window panel blew out on an Alaska Airlines Boeing 737-9 Max seven minutes after takeoff from Portland, Oregon, on Friday. The rapid loss of cabin pressure pulled the clothes off a child and caused oxygen masks to drop from the ceiling, but miraculously none of the 174 passengers and six members heading to Ontario in Southern Califfornia were injured. Pilots made a safe emergency landing.

Hours after the terrifying incident, Alaska Airlines announced that it would ground its entire fleet of 65 Max 9s for inspections and maintenance. CEO Ben Minicucci said Alaska expects the inspections to be completed “in the next few days.”

Alaska Airlines canceled seven flights scheduled to depart from San Francisco International Airport on Saturday, following the decision to temporarily ground its fleet of Boeing 737 MAX 9s.

Affected travelers should work with Alaska Airlines’ customer service directly to rebook tickets, according to SFO airport duty manager Anthony Nguyen: Newark Liberty International Airport, John F. Kennedy International Airport, Washington Dulles International Airport, Chicago O’Hare International Airport, Orlando International Airport, Tampa International Airport and Puerto Vallarta International Airport.

No flights scheduled to depart from San José Mineta International Airport or Oakland International Airport were impacted by the cancellations.

By 9 a.m. Saturday, the airline issued a statement that inspections had already been completed on more than a quarter of their 737-9 fleet, and no concerning findings were reported.

“Aircraft will return to service as their inspections are completed with our full confidence,” the statement said. “Guests whose travel has been impacted can go online to view flight options and rebook travel, place the value of their ticket in their Mileage Plan Wallet for future use, or request a refund. ”

Even a short grounding will pose significant problems for the airline and its passengers — the Max 9 accounts for more than one-fourth of Alaska’s fleet. On Saturday, Alaska canceled about 100 flights, or 13% of its schedule, by midmorning on the West Coast, according to FlightAware.

United Airlines also operates a large fleet of 737-9 Max jets. A United spokesman said Saturday the airline had nothing yet to announce about its Max fleet.

Photos showed a hole in the Alaska jet where an emergency exit is installed when planes are configured to carry a maximum number of passengers. Alaska plugs those doors because its 737-9 Max jets don’t have enough seats to trigger the requirement for another emergency exit.

India’s aviation watchdog told its airlines to immediately inspect emergency exits of all Boeing 737-8 Max planes, a slightly smaller model than the 737-9 Max. The country’s aviation authority complained about a lack of guidance from Boeing.

The Federal Aviation Administration and the National Transportation Safety Board said they would investigate Friday’s incident.

Boeing has offered only a brief statement.

“We are aware of the incident involving Alaska Airlines Flight 1282,” the company said Friday night. “We are working to gather more information and are in contact with our airline customer. A Boeing technical team stands ready to support the investigation.”

The plane involved is brand-new — it began carrying passengers in November and has made only 145 flights, according to Flightradar24, a flight-tracking service.

The Max — there are currently three versions: the 8, 9 and 10, which differ mainly in size — is the newest version of Boeing’s venerable 737, a twin-engine, single-aisle plane frequently used on U.S. domestic flights.

More than a decade ago, Boeing considered designing and building an entirely new plane to replace the 737. But afraid of losing sales to European rival Airbus, which was marketing a more fuel-efficient version of its similarly sized A320, Boeing decided to take the shorter path of tweaking the 737 — and the Max was born.

A Max 8 jet operated by Lion Air crashed in Indonesia in 2018, and an Ethiopian Airlines Max 8 crashed in 2019. Regulators around the world grounded the planes for nearly two years while Boeing changed an automated flight control system implicated in the crashes.

Federal prosecutors and Congress questioned whether Boeing had cut corners in its rush to get the Max approved quickly, and with a minimum of training required for pilots. In 2021, Boeing settled a criminal investigation by agreeing to pay $2.5 billion, including a $244 million fine. The company blamed two relatively low-level employees for deceiving the Federal Aviation Administration about flaws in the flight-control system.

Boeing has estimated in financial reports that fallout from the two fatal crashes has cost it more than $20 billion. It has reached confidential settlements with most of the families of passengers who died in the crashes.

After a pause following the crashes, airlines resumed buying the Max. But the plane has been plagued by problems unrelated to Friday’s blowout.

Questions about components from suppliers have held up deliveries at times. Last year, the FAA told pilots to limit use of an anti-ice system on the Max in dry conditions because of concern that inlets around the engines could overheat and break away, possibly striking the plane. And in December, Boeing told airlines to inspect the planes for a possible loose bolt in the rudder-control system.

A passenger on a Southwest Airlines jet was killed in 2018 when a piece of engine housing blew off and shattered the window she was sitting next to. However, that incident involved an earlier version of the Boeing 737, not a Max.
