Channex dont seem to be having a lot of luck with the F27 of late, this is the second inflight engine shutdown in a month and both major problems.
At one time channex had the lowest RR dart shutdown rate and the longest TBO of eny dart user due to the engine management policy that was flight crew SOP and the hard work of the engineering section.
Unless some thing has changed inside channex this all sounds like an unfortunate statistical blip to me.
