I've always wondered what this bracket type device over the back of the wheels is used for... anybody know?

It's called a gravel kit. Common on MD-80s because they throw lots of debris into the wing and engines. It simply defelcts the debris way from sensitive areas.

I'm not positive..But I believe it is used for pushback from the gate. Most older aircraft have these types of brackets on the front wheels. Please correct me if I'm wrong.

Thanks for the quick replies... I figured it was something more technical than a deflector... thanks again.

Sorry but it is just a spray bar to keep water kicked up by the wheels from going into the engines.

This way MD-80 operators don't have to buy chined tires that do the same thing but are more expensive.

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......  Smile
