Lion airs flight the day before , they say the switches where turned off ? I believe the stick shaker was on constantly for entire flight ?
This raises an interesting point:
Ordinarily the switch position ought be detailed in the maintenance documents. Presumably the maintenance entry ought have mentioned the STAB TRIM CUT OUT switches with guard open in cutoff?
This is pertinent because engineering or the next crew must have reset the STAB TRIM CUT OUT switches.
