This appears to be a simple bent or bad AOA probe giving a erroneous stall warning. Poor jetway operation is the usual cause of a bent probe. I have had it on a L1011 and 727 plus several military aircraft. It’s a no brainer to handle on a non FBW aircraft. You know you are not stalling based on airspeed, attitude, power and phase of flight. Disconnect the electrical trim and fly the aircraft. When time permits pull the stick shaker circuit breaker. What is hard to understand is why over 4 flights this was not diagnosed or fixed. You wonder if the pilots or mechanics even knew the stall warning comes off the AOA probe.
