Description |
A failed oxygen-charging valve of an aircraft was analyzed. Evidences suggest that fire was caused due to leakage in the valve. Analysis shows that the leakage was due to failure of the sealing in the valve. This had resulted in sudden movement of the spindle in the axial direction. The movement appears to have caused frictional heating at the threaded region of the spindle. The heat thus generated resulted in ignition of aluminium in the presence of high-pressure oxygen. Following this, the hand-wheel along with the spindle had popped out of the valve by fracturing the clamping nut.
