DC-10 Fatigue Life

Sat Dec 20, 2003 5:14 am

Though it has been said on here that Douglas aircraft are "built like tanks", I was curious what kind of fatigue life is expected of them. DAS Air Cargo is currently offering a DC-10F for lease with 120,000 (!!!) hours on it. I have also seen a former CO bird with 115,000 on it. Just curious since 100,000 seems to be the magic number on te 747 before wing spars come due for an expensive replacement.

Just to add here, atleast a couple of Korean Air 742F are well over 105,000hrs on the clock.

If I remember right an instructor told us that as long as you do the regular checks and comply with service bulletins and AD´s there is no lifetime limit on wings, stabilizer and fuselage of a DC-10 or MD-11.
Douglas used to build their planes to last.
The B-17s you see today are almost all licence built by Douglas during the war. They built them to commercial aircraft quality specs, with full corrosion proofing, unlike Boeing, who used to build them "quick and dirty"

I think that's a true statement. I guess that's why there are still so many DC-8's, DC-9's and DC-10's still flying.

It's not the Hours, but the Cycles that are the big 'killer' to an airframe.
