Not clear whether the 20Aug16 NH609 was a failure, or an inflight precautionary shutdown. While the 14Aug16 ANA looked to be a catastrophic engine failure (lots of fire, parts on the runway), the Jetstar engine was shutdown inflight due to low oil pressure.
All 787, but different engine types. The two NH 787's were Trent 1000's, while the Jetstar was a GE.
During that same time frame 3 A320's, 2 330's, 3 737's, 1 777, and 1 A300, and 1 CRJ all shut down engines inflight (failed??). Engine shutdowns happen all the time.
