Is it normal ops to dispatch an airplane after a stick shaker was on throughout the previous flight (Lion Air 610)? I've been studying Figures 5 and 7 of the Lion Air interim report and cannot understand why the airplane was dispatched on the "Loss-of-control" flight when the Left stick-shaker was on throughout the entire previous flight (Figure 7). Can this occur in normal operations everywhere?
I have no experience with ground operations (just 35 years with design of flight control equipment), so I'm asking the airline folks here. (I understand that often multiple causes lead to a crash, so I'm looking for understanding, not blame.)
Well, if the shaker was running abnormally like that, the crew would have done a QRH procedure, if any, for that condition, and reported the snag at the next stop, and something would have been done by maintenance to release the plane.  Like a part was changed, or the problem went away and couldn't be duplicated after a test was done on the ground, whatever was required to get a maintenance release.  It would have to have been released as serviceable, one way or another.
