Missing door ‘plug’ may hold vital clues to how a gaping hole blew open on Alaska Airlines jetliner

Investigators were searching Sunday for the piece of fuselage that blew off a Boeing airliner over Oregon on Friday, hoping to gain physical evidence of what went wrong.

The gaping hole in the side of the Alaska Airlines jet opened up where aircraft maker Boeing fits a “plug” to cover an emergency exit that the airline does not use.

The plugs are on most Boeing 737 Max 9 jets. The Federal Aviation Administration has temporarily grounded those planes until they undergo inspections of the area around the door plug.

Why the plug is there

Some larger Boeing 737s have emergency exits on fuselages behind the wings to meet a federal requirement that planes be designed so passengers can evacuate within 90 seconds even if half the exits are blocked.

The more passenger seats there are on a plane, the more exits are required.

Some carriers, including Indonesia’s Lion Air and Corendon Dutch Airlines, cram more than 200 seats into their Max 9s, so they must have extra emergency exits. However, Alaska Airlines and United Airlines configure their 737 Max 9s to have fewer than 180 seats, so the planes don’t need the two mid-cabin exits to comply with U.S. evacuation rules.

On Alaska and United, the only two U.S. airlines using the Max 9, those side exits near the back of the plane are replaced with a permanent plug the size of an exit door.

Are they only on Max 9s?

No. Boeing also makes bigger versions of its 737-900 – a predecessor to the Max – and the Max 8 with space for extra exits in the back. Buyers of those planes also may opt to have either exit doors or plugs installed.

Who installs the plugs?

A spokesman for Spirit AeroSystems – which is unrelated to Spirit Airlines – confirmed to The New York Times that the company installed door plugs on Max 9s, including the plug on the Alaska Airlines plane involved in Friday’s incident. The Seattle Times reported that door plugs are assembled into 737 fuselages at Spirit’s factory in Wichita, Kansas.

Spirit AeroSystems declined to answer questions from the Associated Press. Boeing declined to comment on the issue.

The Boeing supplier

Spirit is Boeing’s largest supplier for commercial planes and builds fuselages and other parts for Boeing Max jets. The company has been at the centre of several recent problems with manufacturing quality on both the Max and a larger plane, the Boeing 787 Dreamliner. Last year, Boeing and Spirit AeroSystems discovered improperly drilled fastener holes in a bulkhead that keeps 737 Max jets pressurized at cruising altitude.

The investigation

Officials with the National Transportation Safety Board, led by the board’s chair, Jennifer Homendy, arrived in Portland, Oregon, on Saturday to begin an investigation that is likely to last a year or longer. Homendy declined to discuss possible causes when she briefed reporters on Saturday night.

The NTSB team includes a metallurgist, and Homendy said investigators will look at the exit-door plug if they can find it, as well as its hinges and other parts.

Examining the damage to the door will be crucial to the investigation, according to independent experts.

“The good thing about metal is that metal paints a picture, metal tells a story,” said Anthony Brickhouse, who teaches accident investigation at Embry-Riddle Aeronautical University in Daytona Beach, Florida. “I’m pretty confident they will find the piece that came off, and they will be able to speak to scientifically what happened to cause this failure.”

Brickhouse said the exit doors, whether plugged or not, are not necessarily a weak point in the fuselage. He had never heard of an exit door plug falling off a plane before Alaska Airlines flight 1282.

Were there warnings?

Aerospace analysts for the investment bank Jefferies wrote that the plane involved in Friday’s incident experienced pressurization issues on two earlier flights. The NTSB has not commented on the plane’s history, but Homendy said investigators would examine maintenance records even on such a new plane.

Other fuselage blowouts

There have been rare instances of holes opening in the fuselages of airliners. In most cases, they have been the result of metal fatigue in the plane’s aluminum skin.

In the most horrific case, a flight attendant for Aloha Airlines was blown out of the cabin of a Boeing 737 over the Pacific Ocean in 1988 after an 18-foot-long chunk of the roof peeled away. Her body was never found. The tragedy led to tougher rules for airlines to inspect and repair microscopic fuselage cracks before they tear open in flight.

In 2009, a hole opened in the roof of a Southwest Boeing 737 flying 35,000 feet over West Virginia. And in 2011, a 5-foot-long gash unfurled in another Southwest Boeing 737, forcing pilots to make an emergency landing at a military base in Arizona. No one was injured in either of those cases, both of which were blamed on metal fatigue.

Roots sees room for expansion in activewear, reports $5.2M Q2 loss and sales drop

Published

 on

 

TORONTO – Roots Corp. may have built its brand on all things comfy and cosy, but its CEO says activewear is now “really becoming a core part” of the brand.

The category, which at Roots spans leggings, tracksuits, sports bras and bike shorts, has seen such sustained double-digit growth that Meghan Roach plans to make it a key part of the business’ future.

“It’s an area … you will see us continue to expand upon,” she told analysts on a Friday call.

The Toronto-based retailer’s push into activewear has taken shape over many years and included several turns as the official designer and supplier of Team Canada’s Olympic uniform.

But consumers have had plenty of choice when it comes to workout gear and other apparel suited to their sporting needs. On top of the slew of athletic brands like Nike and Adidas, shoppers have also gravitated toward Lululemon Athletica Inc., Alo and Vuori, ramping up competition in the activewear category.

Roach feels Roots’ toehold in the category stems from the fit, feel and following its merchandise has cultivated.

“Our product really resonates with (shoppers) because you can wear it through multiple different use cases and occasions,” she said.

“We’ve been seeing customers come back again and again for some of these core products in our activewear collection.”

Her remarks came the same day as Roots revealed it lost $5.2 million in its latest quarter compared with a loss of $5.3 million in the same quarter last year.

The company said the second-quarter loss amounted to 13 cents per diluted share for the quarter ended Aug. 3, the same as a year earlier.

In presenting the results, Roach reminded analysts that the first half of the year is usually “seasonally small,” representing just 30 per cent of the company’s annual sales.

Sales for the second quarter totalled $47.7 million, down from $49.4 million in the same quarter last year.

The move lower came as direct-to-consumer sales amounted to $36.4 million, down from $37.1 million a year earlier, as comparable sales edged down 0.2 per cent.

The numbers reflect the fact that Roots continued to grapple with inventory challenges in the company’s Cooper fleece line that first cropped up in its previous quarter.

Roots recently began to use artificial intelligence to assist with daily inventory replenishments and said more tools helping with allocation will go live in the next quarter.

Beyond that time period, the company intends to keep exploring AI and renovate more of its stores.

It will also re-evaluate its design ranks.

Roots announced Friday that chief product officer Karuna Scheinfeld has stepped down.

Rather than fill the role, the company plans to hire senior level design talent with international experience in the outdoor and activewear sectors who will take on tasks previously done by the chief product officer.

Talks on today over HandyDART strike affecting vulnerable people in Metro Vancouver

Published

 on

 

VANCOUVER – Mediated talks between the union representing HandyDART workers in Metro Vancouver and its employer, Transdev, are set to resume today as a strike that has stopped most services drags into a second week.

No timeline has been set for the length of the negotiations, but Joe McCann, president of the Amalgamated Transit Union Local 1724, says they are willing to stay there as long as it takes, even if talks drag on all night.

About 600 employees of the door-to-door transit service for people unable to navigate the conventional transit system have been on strike since last Tuesday, pausing service for all but essential medical trips.

Hundreds of drivers rallied outside TransLink’s head office earlier this week, calling for the transportation provider to intervene in the dispute with Transdev, which was contracted to oversee HandyDART service.

Transdev said earlier this week that it will provide a reply to the union’s latest proposal on Thursday.

A statement from the company said it “strongly believes” that their employees deserve fair wages, and that a fair contract “must balance the needs of their employees, clients and taxpayers.”

On an adjusted basis, Transat says it lost $1.10 per share in its latest quarter compared with an adjusted profit of $1.10 per share a year earlier.

Transat chief executive Annick Guérard says demand for leisure travel remains healthy, as evidenced by higher traffic, but consumers are increasingly price conscious given the current economic uncertainty.
