2019.
The new mandate, issued by FAA with a Feb. 4 effective date and expected to be adopted globally, limits extended range (ETOPS) operations for "Package B" Trent 1000s with more than 1,000 cycles on its intermediate pressure compressor (IPC) blades to 180 min. from the nearest suitable airport.

The fatigue-cracking issue was discovered on newer-standard Package C-configured engines, leading to inspection mandates and a 140-min. ETOPS limitation

What is with all of the blade issues?
