CF6-80C2 modification programmes, Issue 48 Oct/Nov 2006
The build standard of the CF6-80C2 series has improved during its 20 years of production, and has required few modifications or upgrades. There are some upgrades that are appropriate for airlines operating in harsh environments and suffering poor on-wing reliability. The HPT upgrade and Tech CF6 programmes are intended to improve engine performance. Their high cost means they can only be justified for engines that are operating in harsh environments and that suffer short maintenance intervals and high shop visit costs.
