I don't expect this to impact Delta taking A330neos. Delta is not first in line for A330neos so other airlines can deal with initial entry into service problems. Converting to A350s would lose some of the launch discount pricing that they got.
I think you're clutching at straws.
1 - There isn't a spare parts issue. The largest RR spares warehouse is located in Singapore which has a plethora of flights to BKK a day. That Thai is having issues with its spares pool is more indicative of a logistics or communication issue than one caused by the RR supply chain. Larger RR 787 fleets don't have any issues with spares so I'm not sure why Thai does.
2 - There are no T1000 blade and overhaul "issues". In fact looking at the LLP cycle limits, the two engine types compare favourably.
3 - The T1000 is proving to be a far more robust engine than the GEnx. I recall from a recent feedback session that the GEnx has a higher EGT degradation rate than the RR. In the first 1000 cycles, the GEnx1 at 76k rating loses 3C more than the Trent and with hotter climes and higher ratings, that difference is even more marked in favour of the latter.
Well how do you explain these quotes if you believe it is straws?
"Due to the shortage of Boeing 787 Dreamliner engine spare parts, it is necessary that some aircraft of this type must be parked and temporarily cannot be operated, which is a problem that affects Thai and other airlines worldwide whose 787 aircraft are equipped with Rolls-Royce Trent 1000 engines that have turbine blade problems," says Thai's acting president, Usanee Sangsingkoo, in a statement.
Last week ANA said fan blades in the turbines of Trent 1000 engines on aircraft making short-haul flights were suffering from corrosion faster than expected.
As a result, the airline said it could cancel up to 300 flights as it takes aircraft out of service for repairs to the engines.
The Trent 1000, Trent 1000 ten and Trent 7000 have some issues. They aren't impossible to overcome, but there is risk with the engine that could impact deliveries for Delta as it is delaying the whole A330neo program and could be a reason for Delta to convert A330neos to A350s
