Ahh, a subject once again after my own heart.
The PS90A is the only solely Russian-produced high-bypass turbofan. It has about 35,000 lbs of thrust, about 10,000 more than previous Soloviev turbofans, but is considerably less powerful than, say, the RB211 on the 757. Plus the PS90A was beset by what Perm/Soloviev originally described as "teething problems." In-flight shutdowns, various malfunctions, fires, etc. To such an extent that anyone traveling to Moscow will see at least two IL96-300s with engines off the wings at any given time, sitting useless on the tarmac at Sheremet'yevo. Aeroflot and Perm struck an agreement, whereby Aeroflot would pay for the engines on the IL96-300 fleet only during such times as they were operational or being maintained according to schedule, and that Perm would be fully financially responsible for unscheduled maintenance and breakdowns, supplying working engines free of charge until the originals could be made serviceable.
Generally, Aeroflot has been quite disappointed with the less-than-promised range and abyssmal reliability of the IL96-300 engined with PS90As, regardless of performance improvement packages and Perm's promises. True, the IL96-300 has made possible non-stop flights from Moscow to San Francisco and Los Angeles, but these routes are now being operated by Boeing 767-300ER aircraft, because of their reliability and efficiency. The 767 flies the same route as the IL96-300, using 1/3 less fuel on two engines.
To say that the PS90A is comparable to Western engines is optimistic, at best. The spotty reliability and average fuel economy of the PS90A is the reason the PW2337 was chosen by Ilyushin to power the IL96M/T. Derivatives of the PS90A also power the domestic version of the Tupolev TU204, but that aircraft can also be equipped with RB211524s similar to those available on the Boeing 757. Why would Russian aircraft manufacturers choose Western engines if there is a Russian one which is just as good?
Lastly, there has been talk of Pratt & Whitney establishing a joint venture with Perm/Soloviev to produce aircraft engines. This would certainly revolutionise Russian aircraft engine manufacturing, and bring about variants which would truly be world-class.
