The FAA have restricted all high level flight operations due to a series of engine surges.
Well, restricted from high-level flight above FL370.

The AD says that carbon build-up on the static vane of the PW 610F-A engines could result in engine surges and, "
In some cases, this could result in flight and landing under single-engine conditions."
I find this a strange statement - assuming each engine has its own static vane (and I'm not an engineer, so I stand to be corrected), and assuming that one engine is likely to accumulate as much carbon build-up as the other at levels above 370, should not the statement caution that a complete loss of engines
could result?
