Beating this subject to death, I guess, and it's off topic to mil.
surplus radio equipment. Absolutely, the mechs. at the last station
should have grounded that ship with it's behavior on the inbound flt.
leg. That's primary flt. controls and you should_not_reset a C.B.,
self-test it and send it down the road. The stabilizer was constantly
trimming leading edge up to bring the nose down, when the faulty angle
of attack sensor kept triggering the MCAS. The indicator for stab.
position is on the pedestal right inboard of the manual trim wheels but
the crew would have also seen the manual trim wheels moving. I'm sure
the airspeed indicator on the side with the faulty AOA sensor would have
also been unreliable. I've seen that cause an airspeed problem plenty
and it has to do with air data computer calculations. I'm at a loss
trying to understand why those two pilots didn't throw the stab. trim
cutout switches also. Just makes no sense at all, but Lion Air is
trying to blame it on Boeing. Sure looks to me like a bad maint. crew
and a bad flt. crew. Just my .02 and I won't clog up the forum with any
more.

>From an article an Aviation Week and Space Technology I understood that the stab was going up and down. Usually, when a stab runs away, it goes to a stop and stays there. I do not know the 737, but the DC-9 had a stab position indicator as well. In the case of a stab run away, the thing to do was to fly the plane, with the other pilot disconnecting the switches and than run the stab manually.
>
>Apparently, two previous crews had experienced the same problem, disconnected the stab and flew back. So, two other crews managed the emergency properly. The management computer told pilots and maintenance about a disagreement between the two AOAs. Ground crew should have grounded the plane and follow procedures; instead, they pulled the breakers and reset the computer to make the fault go away.
