Hi again all,
I have just made a posting to the Tech Log forum about the behaviour of pitch trim systems in aircraft such as the B737.
I have made reference to this accident, and the Tatarstan Airlines B735 that crashed in Kazan, Russia in 2013. These two accidents have almost identical vertical profiles. Both crashed onto the aerodrome, beside the runway, steeply nose down and at high speed.
