Pilot Who Hitched a Ride Saved Lion Air 737 Day Before Deadly Crash (bloomberg.com)

As the Lion Air crew fought to control their diving Boeing 737 Max 8, they got help from an unexpected source: an off-duty pilot who happened to be riding in the cockpit. Bloomberg reports: That extra pilot, who was seated in the cockpit jumpseat, correctly diagnosed the problem and told the crew how to disable a malfunctioning flight-control system and save the plane, according to two people familiar with Indonesia's investigation. The next day, under command of a different crew facing what investigators said was an identical malfunction, the jetliner crashed into the Java Sea killing all 189 aboard.

The previously undisclosed detail on the earlier Lion Air flight represents a new clue in the mystery of how some 737 Max pilots faced with the malfunction have been able to avert disaster while the others lost control of their planes and crashed. The presence of a third pilot in the cockpit wasn't contained in Indonesia's National Transportation Safety Committee's Nov. 28 report on the crash and hasn't previously been reported. The so-called dead-head pilot on the earlier flight from Bali to Jakarta told the crew to cut power to the motor driving the nose down, according to the people familiar, part of a checklist that all pilots are required to memorize.

    Is this a 737 Max 8 problem or a training problem?

      It seems like all of the above. If you have a bad problem the day before that the main pilots didn't know how to solve and you continued flying those aircraft without making damn sure all the rest of your pilots knew how to solve it, then that's just wrong.

      I am a pilot although not type rated in 737. This is a pilot training issue primarily. Secondary there appears to be a failure to fully explain the behavior of the new MCAS trim mode so it can be differentiated from runaway trim. The response to the problem would be the same as runaway trim, turn off trim power, re-trim the aircraft manually. Indication of this new MCAS trim problem is almost identical to runaway trim. The difference is MCAS runs briefly and will repeat until it reaches its limit, whereas runaway trim will run continuously until it hits the stops. Turning off trim and manually re-trimming restores normal flight control in both cases.

      No.

      If you depend on some knowledge that's both obscure to pilots, and hidden from them by Boeing, that is not a "training problem".

      "Your car is going to suffer a deadly crash unless you know how to disable some system that GM did not tell you about, while in the midst of trying to deal with an uncontrollable car, and you were intentionally prevented from even knowing that system exists."

      Sorry. No. Just no.

    And yet he might go, "Holy shit, we're all gonna die if I don't do something! What kind of fixes do I know about for electronics? Alright. Turn it all off and back on."

    And judging from the summary that just might have worked.

  4. A blow to US civil aviation influence by wired_parrot · · Score: 5, Insightful

    One of the bigger long-term consequences of these MAX-8 incidents will be the impact on the FAA's influence in the civil aviation world. One little commented fact is that when the MAX-8s were grounded it was the Chinese civil aviation authorities who led the world in grounding the 737 MAX. This was unprecedented, as most civil aviation authorities have tended to follow the lead certification authority of the manufacturer, the FAA in this case, before issuing a grounding. This was the case in previous grounding - the 787 dreamliner in 2013 and DC-10 groundings in 1979 were both led by the FAA.

    Additionally, it now appears both Transport Canada and EASA are no longer willing to accept FAA certification. Other aviation authorities have in the past accepted FAA certification without challenge. if other authorities no longer trust the FAA to do its oversight properly Boeing will be forced to carry out multiple certification assessments for each civil aviation authority, and that will carry with it a considerable delay and financial burden.
