There is a lot of contract variation with power-by-the-hour but, I think, if you have power-by-the-hour the cost would generally be absorbed by the engine owner (usually the engine OEM but not always).
And this led to an awful lot of friction between QF
when one of RR
's engines decided to go all happy on QF
's A380 a couple of years back. I believe that in QF
's PBTH agreement, RR
retains ownership of the engine, and so RR
was responsible for fixing the aircraft and I think QF
tried to hit them up for loss of use, too, especially since it affected a lot of the fleet.
