 HSC is a home station check and it is an in-depth inspection into the aircraft's airworthiness. The aircraft has several different kinds of inspections that it goes through. This is the one where we start taking panels off and doing a more in-depth inspection. What we're looking for is anything that is broken, loose, damaged, corrosion is also a big portion of our inspection. The wheel and tire shop is an additional duty that we do here during or in this flight. Basically anytime that a tire is worn or damaged the technicians will remove them and bring them back to the back shop where we will tear them apart. We take, you know, remove the rubber, we will then go ahead and take apart the wheel assembly itself. We do a thorough wash on it. It gets an NDI inspection. They'll come over and do an eddy current on it, make sure that there's no defects that is to the naked eye and then we will build it back up. We put it back onto the rack and then the technicians can come back in and use them. The process after its inspection is to lube its parts first then we put our valve stem inside the outboard half of the wheel along with the pressure relief valve. After we've put all the parts into the outboard half we then place the inboard half onto our hydraulic lift. We place the bolts around with washers on the lift and then place the outboard half or inboard half on top of the bolts on the lift. We then put the inboard half onto the tire. After the tire has been lifted up with the inboard half we put the outboard half on and we began putting washers and nuts on. Basically you got two nose tires anytime one is bad you change both of them. As far as mains there are 12 per aircraft we can go through quite a quite a few. I know that we are allotted to have 24 mains ready at all time and 12 nos. We also have an additional amount of wheels that we keep and what is referred to as a risk kit and that is you know if we have a supply shortfall we can go grab those items. It's a very rewarding job to know to know that what we do gets these aircraft in the air and back down safely and the flight crews home to their families safely every day.
