Unsafe Condition
Three in-service failures of the auxiliary fuel tank venting system have been reported, leading to the inability to supply the complete auxiliary fuel quantity to the main tanks and the collapse of the auxiliary tank. It is suspected that the vent lines were obstructed either by ice accretion under certain climatic conditions or by blockage of the vent valves because of fuel contaminants.
