Probable cause
The overstress fracture of the elevator control tube due to reduced wall thickness from water intrusion and subsequent corrosion. Contributing to the accident was the lack of a drain hole at the bottom of the elevator control tube, which allowed the tube to collect water, and the mechanic’s inadequate inspection of the elevator control system during the recent condition inspection.
