After a Boeing 777 Rained Failed-Engine Debris on Neighborhood Below, More Planes Grounded (msn.com) 118

Posted by EditorDavid from the engine-failure dept.
After a twin-engine, wide-bodied Boeing 777 took off from a Denver airport — carrying 231 passengers and 10 crew members — its right engine failed. It began dropping debris on several neighborhoods below, CNBC reports.

America's Federal Aviation Administration issued a statement saying it was "aware of reports of debris in the vicinity of the airplane's flight path," CNBC adds, noting that less than 30 minutes later the plane had returned to the airport. No passengers were injured.

Today the FAA is issuing an emergency airworthiness directive, "requiring immediate or stepped-up inspections" of similar planes. In a statement FAA Administrator Steve Dickson said the move "will likely mean that some airplanes will be removed from service." Dickson's statement suggests the inspections will be directed at hollow fan blades that "are unique to this model of engine, used solely on Boeing 777 airplanes."

And more steps are being taken in Japan, reports Bloomberg: Meanwhile, Japan's transport ministry on Sunday ordered ANA Holdings and Japan Airlines to ground Boeing 777 planes they operate following the Denver engine failure. ANA operates 19 planes and JAL 13 with Pratt & Whitney's PW4000 engine that saw a failure with United Airlines plane.

            I worked at Boeing from 2007 to 2009, albeit not in the Commercial Aircraft unit.

            Some observations:

            1. Weird management system. I had three separate lines of management. One on my program, people I worked with and saw every day. A "HR Management" chain, running out of the West Coast (I was in Virginia), who I would occasionally hear from via email. And a "Career Field" chain, for Systems Engineering, based in Philadelphia, that I never heard from personally, but got occasional email blasts from, every year or two.

            2. Disappearing benefits. When I joined Boeing, health insurance was free for me and my family, not even any co-pays. Education was encouraged, with 100% coverage of tuition, fees, and books for anything other than Law School.

            Over the next two years, health insurance shrank: first, co-pays, and then charging for family coverage, and by the time I left, everyone paid for their coverage,

            Education suddenly switched to "all programs must be approved in advance by all three management chains, must be an approved area for your job category, and reimbursement after submission of a 'B' or higher grade", and several months later, it switched again to requiring approval in advance for each individual course.

            I left Boeing several months after that: luckily, I had completed my Master's 3 months before the new Education policy hit. . .

              Everything you describe is pretty normal.

              While I've never seen HR as part of the management chain per-se, the management system you describe is incredibly common. There's management of a project "These people are working on building a jet-powered smoothie machine" then there's management of a discipline "These people are systems engineers.

              I have not known of a company offering totally free health insurance in 20 years. In my experience shrinking of benefits happens slowly and subtly. A switch from PPOs to HMOs to HSAs. The new offering is cheaper and has some perk like the company kicking-in money, so everyone goes to that. Then they raise the price to the original price over a few years, then they remove the incentives, then they retire the old plan.

              Tuition reimbursement is expensive and every company I've worked for required everything you have listed, and the reimbursement was based on continued employment at some minimum performance standards for a few years. They don't like people taking tuition money then leaving. Funny story on that: I worked for a company that offered tuition reimbursement, but the reimbursement vested, so they employee was required to partially repay the tuition if they left within like 2 years or something. An employee went through school for comp sci then got laid-off a few months later. So the company had to pay the entire amount and release the "golden handcuffs." A few months later that person got re-hired for a new project, at a new position, with higher pay since they now had the degree. Great deal for the employee! And they did stick around!

If the shrapnel hadn't gone through said window into your head or ripped the wing off then there's a really good chance the pilots can bring the plane back to the ground without killing anyone.

        On the one hand, aircraft designers ensure that, on a two-engine plane, one engine can fail at any time and the passengers should still be safe.

        On the other hand, it's reasonable to worry that the other engine will fail, especially for the same -- obviously unexpected -- cause. If one engine fails so spectacularly, it might lead to a common cause failure for the other engine as well.

          Engines that fail spectacularly typically have something wrong with them thats unique to that engine.

          Its the engines which fail non-spectacularly which you have to worry about with regard to the other engine - for example, Air Transat flight 236, where a burst fuel line led to the pilots unknowingly dumping all their fuel overboard, 200 miles out over the Atlantic ocean. Or British Airways flight 38, where both engines failed within moments of each other after being run back up on final approach to London Heathrow - in that case, a design fault in the fuel heater caused the fuel lines to ice up, starving the engines.

          All aircraft have been, since the 1980s, designed around the concept of "ETOPS" standards, which dictate how long an aircraft must be able to fly when suffering an engine out - originally just for twin engine aircraft that want to fly long distances, its since been extended to 4 engine aircraft as well. These days, ETOPS is up to 370 minutes (for the A350XWB), meaning it can fly for more than 6 hours before having to land after an engine out scenario.

          Failure of both engines is unlikely, but debris from the failed engine striking the wing or similar is a lot less unlikely. Not only can it cause severe structural damage but since they have a wet wing there's also a chance of fire.

          • I would have thought gravity and wind would take care of this (since on commercial jets the engines are usually mounted under the wings), but maybe I would have thought wrong. I guess engine debris could strike the wing if there were a catastrophic turbine failure (sort of like the failure that cut the hydraulic lines on that DC10 flight UAL 232 so many years ago). Are there other circumstances under which engine debris could strike a wing?

        Yes, and in addition to the Feb. 13, 2018, SFO to Hawaii, incident with this 777-200 engine model mentioned in msn.com article, there was an incident "JAL 777 flying to Haneda from Naha on Dec. 4," 2020, reported by the Washington Post. https://www.washingtonpost.com... [washingtonpost.com]

        I suppose that rules out the cowling failing first, or a bird strike, as a cause. FAA quoted in the WP: "the inspection interval should be stepped up for the hollow fan blades that are unique to this model of engine, used solely on Boeing 777 airplanes."

        From msn.com: "The fan blades on this specific type of PW4000 are hollow and made of titanium. The cracks appear to start from within the surface, making them impossible to detect on the surface. Airlines can use technologies such as ultra sound to find cracks beneath the surface."

        Let's give P&W some credit though for designing an engine that did not blow apart and cut into the aircraft, which has happened before. Apparently the outer cylinder is Kevlar on this or all jet engines.
