VgnAtl747: The DC-9 Maintenance manual, Chapter 32-20-1 states: "To prevent water spray being directed to the engine air inlet as the aircraft rolls through standing water, a water deflector is installed aft, inboard, and outboard of the nosegear wheels. The water deflector deflects the spray towards the ground preventing an excess of water spray to the engine air inlets." Regards,

In SAS,the deflectors also deflects sand and gravel since we operate at snow-covered and sanded runways during winter.They're also effective against slush.There are also,at least on our machines,deflectors mounted on the mainwheels,too,a T-shaped device protruding out between the twin mainwheel tires.

As Fbu states, the spray deflector bar also has a protective effect against gravel and minor FOD. In addition, a burst tire, would not inflict maximum damage on for example the flap or engines, when we talk about the main gears.....For info, the spray deflector, have a little rubber protrusion marking the wear limit before replacement for maintenance......
