Do they have to change them? How is it done and how often?How do they change tires on a Boeing 747?Aircraft Tires are changed based on wear limits. Their lifespan is determined by the number of landings and/or runway conditions such as icy or wet, by how well inflated they are, etc. The appropriate aircraft maintenance manual will give you the acceptable wear limits.
They are replaced according to the maintenance manual instructions. These instructions give you the tools necessary to perform such task. Keep in mind that these instructions may vary from plane to plane so make sure u are using the correct one.
To summarize the process a little, let me tell you that a 60 ton or more oleo/pneumatic jack is used to lift the tire off the ground. It's a sefety procedure to lift the jack using the nitrogen contained in the tire. This way u are assuring the tire is being deflated too so to prevent a tire explosion.
The nuts and retainers that hold the tire to the axle are removed, the wheel is then removed and a new one is installed. The nuts and retainers are reinstalled and tightened to a specific limit (Torque) and the wheel is lowered to the ground. The last thing u do is check tire inflation pressure.
How do they change tires on a Boeing 747?I don't own a 747 but I do own my own airplane. We have several inspections throughout the year and they all involve inspecting the tires. The tires wear like a car tire. Sometimes you get bald spots on a tire (I even get them on the nose tire although I don't know why). However, most common is that the tires wear out from being weathered (we don't put many miles on them). Aircraft tires are unlike car tires in that they have tubes in them. The wheel hub splits in two (is held by nut/bolt) and the tire comes off. When you change it you put a new tube in there (with some baby powered so it slides into the tire) and put the tire on. Luckily we don't need all the big equipment to change a tire on a wheel that you need for a car. On the 747 you have two wheel trucks per wing so you can just lift one truck without having to jack up the plane.How do they change tires on a Boeing 747?With a Very big 4 way...
