As result of the blocked pressure sensors and resulting incorrect EPR data autothrottle limited the thrust available at an value that was insufficient to maintain speed. Over 5:35 minutes the aircraft's indicated speed reduced from 290 to 200 knots, the angle of attack increased beyond stall. 20 seconds after the aircraft entered stall the autopilot disconnected causing the aircraft to abruptedly roll left to a bank angle of 140 degrees and a drop of the nose by about 80 degrees. The recorded data suggest that there has been no stall recovery done by the crew. Following the roll and nose down there are control inputs recorded to roll the aircraft right and pull the nose up.
