    Then everyone would know what you are talking about.

    Yeah...I hate acronyms...now, if I'd just practice what I preach...

    A UTAir Boeing 737-500, registration VQ-BPQ performing flight UT-716 from Riga (Latvia) to Moscow Vnukovo (Russia), had been enroute at FL360 and completed the flight with a safe landing at Moscow Vnukovo.

    Passengers reported (on Oct 1st 2017) the aircraft was in cruise flight when the aircraft suddenly entered a dive, the passengers began to pray fearing for their lives. The crew managed to recover the aircraft and landed safely at Vnukovo. It subsequently turned out that there had been an electronic problem with the autopilot suddenly changing mode.

    The airline (also on Oct 1st 2017) however denied any dive or deviation from the flight level (editorial note: supported by the data transmitted by the aircraft's transponder).

    Subsequently, it turns out that the crew didn't understand the behaviors and limitations of the autopilot, hence the word "suddenly". I'll bet...

    Fixed.

    Update in avherald:

    While intercepting the glideslope the crew selected the flaps to 30 degrees. The autopilot went offline, autothrottle remained connected and increased thrust to about 95%, which caused the aircraft to pitch up due the engines underneath the wings producing a pitch up moment. The crew attempted to counteract by pushing the yoke forward and attempted to reduce engine thrust, however, with autothrottle still engaged the engines still remained in high thrust causing the aircraft to pitch up to 45 degrees nose up, the speed decreased to below 100 knots
    That explanation is so unsatisfactory...

    J C !

    Where was the pitch trim when the AP went off, I would love to know.

    Mega ass-hat parlour speculation (Italics especially)

    It seemed they were nose high (maybe trying to slow up some) and maybe intentionally lowered the nose rapidly with very little trim adjustment then flaps go out with more nose up trim effect

    [Break]

    ...Here you are with a plane configured to want to go mega nose up...

    [End Break]

    THEN when you add the underslung engines and the aerodynamics do their thing.

    This feels extremely 3BS and defies logic...just grasping at straws to understand the logic defying 'pull up'.
