Crash: Lion B38M near Jakarta on Oct 29th 2018, .....

On Nov 22nd 2018 the KNKT gave a presentation to Indonesia's Parliament about the findings so far. The KNKT told the parliament that the FDR contained 1790 parameters spanning 19 flights. The last two flights, the flight from Denpasar to Jakarta as well as the accident flight, were showing the same issue, the right hand speed (first officer's IAS) signficantly higher than the left hand speed (captain's speed). The captain's AoA indicated about 20 degrees higher than the first officer's AoA. As result the left stick shaker activated immediately after takeoff and operated, with a brief period where it stopped during a descent shortly after takeoff, continuosly throughout the flight. When the aircraft levelled off at 5000 feet automatic nose down trim inputs occurred which were countered by manual trim up inputs by the crew. The nose down trim inputs were created by the Maneouvering Characteristics Augmentation System (MCAS), a tool which will lower the nose of the aircraft to prevent a stall. Until the end of the flight the automatic nose down trim inputs were countered by manual nose up trim inputs by the crew. During the end of the recording the automatic nose down trim inputs increased, the pilots still trimmed nose up however shorter. Overall the stabilizer trim position moves increasingly towards nose down until it was no longer possible to counter the pitch down moment via the yoke. Throughout the flight there had been no problems with the engines. On the previous flight from Denpasar to Jakarta the same problem existed, the automatic trim inputs however did not occur. The crew must have done something preventing the MCAS system producing the nose down trim inputs. Following the presentation the KNKT released first information in Indonesian including some FDR graphics.

It’s wonderful the world can know that a religion held by pilots can cause manual inputs to override automatic safety adjustments.

"The crew must have done something preventing the MCAS system producing the nose down trim inputs."

Its called switching off the "Stabilizer Trim Main Electric (MAIN ELECT) Cutout Switch" located below the throttle quadrant.

Pretty fundamental stuff when ecountering a "Runaway Stab Trim." as they clearly identified when the report says they "manually trimed" the airplane nose up immediately after takeoff. Turn OFF the damn cutoff switches! How hard is that?

Of course Boeing will be required to take most of the blame (deep pocket rule), but so far what we know, flight crew clearly screwed up.

Have they found the cockpit recorder yet?

Somehow, pilots, likely Muslim, are able to make a plane do stuff it isn’t supposed to, to cause it to crash—even when automated systems forcibly try to resolve the issue.

In other words, we all know Muzzies kill people using planes.

Agreement. This plane should not have crashed.

They are still looking for the voice recorder.

You are reading it completely backwards. The automation was faulty and trying to fly the aircraft into the ground. The pilot and copilot were countering that action by the control system. The pilot and copilot failed to disengage the faulty automatic control system that was diving the plane to the ground.

Stab Trim fault at 2:48. Stab Trim off at 3:05.

Good example. but kinda painful to watch. LoL

Silence the bell, talk to each other, not over each other, and use the trim handle (technique). Didn't know to laugh or what. But then they are young'ins, and we all had to learn sometime.

Also am not seeing anywhere in the preliminary report that the FDR indicates they attempted to engage any of the "Instrument Transfer" switches. I suspect that may have or could have corrected the problem. However . . . With an abnormal AOA left side and abnormal Airspeed right side, would have to see how that works out. But at least try. These boys screwed the pooch on this one.

More importantly, whispers on the street is lack of training (Runaway Stab Trim) which goes to the issue of why the flight crew did not or could not properly identify the abnormal.

Will not matter. Boeing will take the blame and the deep pocket rule will be exercised.

Ok, now I understand what you are saying. I feel sure the investigators should not be blinded by political correctness and overlook any possible causes of the crash. I know that domestic investigators would not overlook anything.

The accident history of the Boeing 737 is posted in Wiki. There are many more accidents outside the US than in CONUS. I pointed this out to a friend when we were discussing the most recent crash, and he said "What are you implying"? I think he was thinking I was casting aspersions upon Asian piloting skills, which I was not doing. I was simply stating a fact.

Would have been darn hard to fly manually with the two AOA disagreeing by 20 degrees and a significant difference in airspeed left vs right. Could an experienced and well-trained crew fly it with that much disagreement in the two readings? It’s reminiscent of the Air France flight from Brazil with the frozen pitot tubes.

I have friends who fly Boeing planes and also some people at Boeing I know. I also receive the NTSB Reporter so I’ll get the latest on the crash.

LION AIR Management overrode maintenance. “The last two flights, the flight from Denpasar to Jakarta as well as the accident flight, were showing the same issue, “
