Do anyone know where airlines dump the unwanted and old airplanes?

Answer 1

Marce's answer is right on. Large airlines sell older (6-15 years old) to lower tier airlines or upstarts or third world airlines. After another 10 years, they'd often go to cargo use.

If you have a lot of capital and fly your planes a lot and your customers want shiny new planes, you buy from Boeing and Airbus.

If a carrier has less money or flies fewer times a day, the older, less efficient aircraft make sense. Just pass the greater fuel costs onto the customers.

Older turboprops (and even piston-engined planes) make a lot of sense for cargo use. (e.g. DC-4 through DC-6's) They use less fuel per ton-mile and cargo doesn't care if the flight takes an extra hour.

A plane typically has to get really old before it gets cannibalized for airframe parts. 30 years or so.

Answer 2

There are usually two endings to an airliner's life.
Some are retired because it is just not economical to fly them due to age and fuel burn, but are otherwise good airplanes. These go to less favoured areas, and end flying in South America, Africa or Asia. A well maintained airplane can have an almost unlimited lifespan.

The worn out airplanes are usually "cannibalized" for parts and metal. The engines, avionics, interiors and electricals are the first to go. Then airframe parts and the rest of the "hardware" gets shipped to repair shops (if they can be reused) or scrapyards for metal recycling. This is done in shops based at airports all around the globe.

The airplanes you see in Mojave or Arizona are usually just waiting for the airlines to recall them into service or sell them. The dry air plus a "mothballing" process keeps them in good shape for many years.
Sadly, some in those areas also end up being chopped up for parts.

Answer 3

There are several aircraft bone yards in California, Mohave Airport and want used to called George AFB near Victorville. Both are in the high desert. Davis Moffit AFB, in Arizona is the repository of mothball air force aircraft.

Answer 4

Well, the airline I work for had to get rid of some old aircraft. They stripped all reusable spares from the aircraft and broke the shell up and sold it as scrap metal.

Answer 5

The Arizona dessert

Answer 6

Mesa Air Field in Arizona or Nevada. You can see hundreds of old planes out their, 747's, dc10's, md80's.

Answer 7

company's who reuse all worn out airplane parts should be sued
they should make new ones instead and use dose airplane parts to build bunkers and sheds

Answer 8

They are parked in the desert, to prevent rust and corrosion from weather. There they remain until a buyer is found or they are "parted-out".

Answer 9

I can't remember where, but if you look around on the internet, you can find some commercial aircraft for sale, and you may be able to see how they are marketed.

Answer 10

They use them for scrap metal/parts or donate them to the airforce for training drills.
