Boeing's 737 Max: Carrying Passengers Again In December? (sfgate.com) 85

"Boeing's much-maligned 737 Max jet could be cleared to fly again in just a few weeks," reports SFGate, adding that one U.S. airline plans to carry passengers "as early as December." Although the Federal Aviation Administration has not disclosed a public timeline for the Max's return to service, approval to lift the grounding could come as early as mid-November, according to Reuters. Boeing executives said they expect to gain FAA recertification before the end of the year. The company will also need to get approval from the European Union Aviation Safety Agency and Transport Canada, which are conducting their own respective reviews...

American Airlines said it plans to operate one daily Boeing 737 Max roundtrip from Dec. 29 through Jan. 4 between its Miami hub and New York's LaGuardia Airport. If it takes off, American will be the first US carrier to bring back the Max...

Other U.S. airlines operating the Max are taking a wait-and-see approach before assigning the fleet type to flights.

      It will be OKed in Europe too with some "to be done in the future" changes required in a new software load coming in a few months. My guess is that if the FAA lifts the grounding order, Europe won't be very far behind.

          Ah, yes, but how many passengers will care? You are correct, this will be an interesting question and I think by the time the general public is back into flying a few years from now, few will remember all this and I'm guessing most of the booking sites won't be showing anything about 737 MAX on them. The aircraft will be quietly rebranded.

        If so, doesn’t that defeat the whole point of the MAX? It was sold to airlines on the basis that the flawed MCAS at the center of this whole ordeal would obviate the need for them to train and certify their 737 pilots on this variant. If that’s no longer the case and heavy retraining will be necessary, the MAX suddenly becomes a LOT less appealing to airlines.

          If so, doesn’t that defeat the whole point of the MAX?

          Not quite. It was the point of MCAS.

          The real point of the MAX was better efficiency using bigger engines (to compete with Airbus). To put bigger engines on the 737 they had to mount them somewhat forward and higher, which changed the handling dynamic (more thrust pitch-up) and would have required (probably minimal) additional pilot training. Boeing thought they could get away with an automated hidden compensation system called MCAS.

          However, MCAS, when given bad info (AOA sensor problems), went berserk and killed people. Previous to the 2 crashes were many reports of the MAX going berserk, but due to the secrecy of MCAS, and the frenetic nature of air travel, and the general nature of human assessment and communication, the problem wasn't fully understood and cataloged until months later with a 2nd crash.

          I don't understand the philosophy nor legality of hiding something from the pilots. Machines break. If the humans don't know MCAS even exists, how can they compensate? The hiding of MCAS removed the possibility that the pilots might have been able to save the plane.

            and would have required (probably minimal) additional pilot training.

            Wrong. The new engine creates an unstable pitch behavior at higher angles of attack that are expressly against the letter and spirit of the certification regulations. Proof [ecfr.gov]

            MCAS was meant to hide this unstable behavior. Of course this was stupid, and using a single sensor for something as aggressive as this new MCAS was criminally, grossly negligent.

            • Not so much unstable as "different." To avoid having to make this a different classification requiring different training, they put in MCAS to try to avoid any different behavior at all. Didn't work out as well as they might have liked, shall we say?
              • There were some suggestions that it might have had a substantial pitch stability issue near stall (malignant pitch up feedback from engine nacelle airflow), but I never took note of anything that confirmed this. Seems like the controls just got unacceptably light during high AoA, slow flight, violating some number of FAR requirements. This seems to be supported by the sneaky shift from a minor stab position tweak (to correct some minor difference in handling) to an AoA-driven free for all.

              I'd call it more compensating for an undesirable behavior rather than masking it. That's hardly stupid, unless you want to call a yaw damper [wikipedia.org] stupid and invalidate about 60 years of aircraft design.

              There are lots of automated systems in any modern transport jet that are there to compensate for undesirable tendencies in certain flight conditions. The stupid thing Boeing did here was the way they implemented MCAS, relying on the single point of failure you mentioned, making it far too easy to fail, as well as

          • The system wasn't hidden. It was part of the pilot training package. The issue is a very much chicken and egg dilemma. The documentation was part of training, but the system existed so that training would not be required and as such pilots were not obligated to read about it or learn about it.

            What was "hidden" (omitted is probably a better word) was some of the details about exactly how to disable it. But the MCAS itself was part of the documentation available.

                There is NO off switch for the MCAS, but there is an off switch for ALL systems that mess with the stab trim including the autopilot and a whole mass of pilot actions that cause automatic trim systems to kick in. All you folks who start yammering on about how the MCAS was somehow novel or unusual are just making noise based on the press reports, and have little understanding of how modern aircraft systems are designed and used.

                  The only OFF switch I know if is to turn off electric trim, and direct verbiage from pilots and test pilots is that if you turn off electric trim, you might be in very very big trouble in some situations, especially where you can't crank the manual trim fast enough to keep the plane from crashing, which the "black box" data showed happened in several MAX plane flight "anomalies".

                  • Boeing made a mistake. I'm saying that this wasn't due to negligence or malfeasance but a process problem. The software safety/Risk management engineering processes missed some stuff, specifically this MCAS issue. So Boing has liability here, and they've already admitted to it. They will be paying out billions in civil courts over the years to come.

                    The FAA ALSO made a mistake on this. They approved and oversaw the process that Boing was using to self certify.

            You make it sound like this is some serious problem to deal with. Dealing with an MCAS failure isn't rocket science, it takes about 5 seconds and is not an unfamiliar process for pilots.

      • An airplane designed in the 1960s cannot be the safest thing in the sky - it lacks a strong fuselage, envelope protection and a lot of other things that have become mandatory for newly designed aircraft since then but were allowed to be grandfathered for older designs.
        It is the by far oldest airliner design out there that is still in regular passenger duty. Even the last passenger Tu-154 has been retired a few days ago.

        • I'll make the argument that some of these older aircraft may be stronger than you're giving them credit for - never heard of a 737 of any vintage breaking up from simple maneuvering loads (Copa 201 entered a dive and broke up at supersonic speeds), only from hitting the ground/structures or other aircraft. There is also the example of Aloha 243 [wikipedia.org] which was able to land safely despite a substantial loss of fuselage structure. This leads to further concerns about the construction/inspection/repair techniques in

            This breaking into three parts after a runway overrun is a common occurence for the 737 - far more often than for the A320 - that can crash land and stay relatively intact, like the one in Russia a couple of months ago. Also the pickle fork cracks many 737NG had.
            Modern standards for the airframe strength require the fuselage to withstand an AFAIR 20% stronger impact than the old standards valid in the 1960s.

            • Agreed, they're definitely not as sturdy as the newer birds - I just don't see them as being fragile, especially when taken in the context of their time. This then brings us back to MAX, and how it would theoretically handle the same types of impacts - especially the 10 stretch.

But yes, have seen many shots of overruns with the characteristic nose/empennage separation.

      The 737-Max flies just fine, it's just that it flies *differently* than the 737-800 and previous generations. Boeing tried to hide this through software and a poorly executed MCAS. They did this to try and make it so the pilots didn't need to take additional training to fly the new type, making it more attractive to the airlines. Turns out that was a mistake. With adequate training to the pilots on how to properly handle the aircraft, it's perfectly safe.

          The max doesn't stall any more easily than any other airliner. If you're super worried about pitch-up-with-throttle behaviour, you'll have to fly on a plane with high mounted engines. Today that basically limits you to a regional jets, or some museum piece McDonnell-Douglas jets still flying in a few places. But at least you'll have pitch-down-with-throttle behaviour!

      • With adequate training to the pilots on how to properly handle the aircraft, it's perfectly safe.

        No, it isn't. Sorry to rain on your parade, but the 737MAX is unstable in pitch at higher angle of attack. This is expressly forbidden [ecfr.gov], exactly because it makes this airplane unsafe. To hide this behind a piece of software controlled by a single sensor doesn't make this any better. Not telling the pilots about it is just the icing on the cake. Boeing management should be put behind bars for this.

        The best remedy would be a larger horizontal tail. But that requires a strengthened rear fuselage and will cos
