## Probable cause

A leak of potable water onto the lateral (aileron) flight control cables, and flap extension cables, which subsequently froze them in place.  An additional cause was the improper procedures used by mechanics for floorboard removal which stretched the rubber hose, and led to the leak, all due to the manufacturer's lack of guidance in the maintenance manuals on floorboard removal.
