On top of having to fix the issues that are still affecting the 787 engines, an entirely new problem has cropped up. Rolls-Royce has issued a Service
Bulletin with instructions to de-pair engines that have reached 24,000 hours or 8,000 cycles. Those engines can be paired with engines that have
fewer than 17,000 hours and 5,000 cycles. Engines that have reached 24,000 hours AND 8,000 cycles can't be paired with engines that have reached
Engines that have reached the 24,000/8,000 threshold appear to be particularly affected by a new engine surge that is still being investigated.
