I remember reading on this forum about Engine commonality on the PW4000 series. It was some big reason why many Airlines selected this same engine to power their 767/777/744/A330/A310s, eg UA/AI. But i can't recollect it now. What is it all about ?

Thanks in advance.

I read this on Wiki too. The main reason to put up this question was to know why AI / UA selected PW to power their fleets, across various types!

Engine component compatibility?
Interchangeability?
Less Spare Parts Inventory?

Normally companys would go for smaller stores inventory because of similiar spares,but at times its a good offer by the manufacturer that tilts scales.
