I have seen UPS 757Fs with both RR and P&W engines
( not on the same aircraft ) and I was wondering if anyone has a good explanation why..
Did UPS change the engine order because of problems, or what ?
UPS has a rather standardised fleet except for this..

UPS ordered PW engines for their first 757 order, however, with the following order they switched to the Rolls Royce engine. The PW agreement with UPS was written so that the PW2000 was to have a 7% better fuel burn than the RR. The PW2000 turned out to have a better fuel consumption to the tune of about 1-2%. When you combine that with the fact that the PW2000 had serious reliablity problems early on in service, UPS desired a switch. UPS at the time had also just begun to re-engine their 727's with RR tay's, RR saw a good opportuinity to pull a coup on PW. They did, and UPS now has both engines.

The first order for 757's was a horserace between PW and RR. Often the one who was first defeated has the best chance in a rematch. PW got the chance and dropped the ball. RR was standing and waiting to pick it up when the time came again.

Of course, when UPS orders new planes, they order large quantities, and can demand a big discount on the engines and airframes. This could explain the variety of engines they use: PW2040 and RB211-535's on the 757, CF-6-80 on the 767, and PW4158's on the A300. aAlso, I wonder if UPS might have received a great price on the -535's since they were ordering the RR Tay for the 727 re-engining, maybe the total cost on both types were reduced substantially for both.

I wonder how much longer P&W will be in business, I mean they lost almost all of it!

Uh - before you write off Pratt for dead, lest ye forget UPS' latest order was for 30 firm plus 30 option A300s powered by PW4000s, an order won in large part due to Pratt's success at fixing the PW2000 problems and their aftermarket support...
