TY anons for the extra info.
Here we see the possible modus operandus appear. Ain't too difficult really, and rather low tech at that, anyone with access really could do it.
Remember (was it Q who alluded as much?) that 7/10 plane crashes were intentional/fabricated/targeted hits.
2 instances of a same problem on a similarly places engine in less than a year.
Wonder if it's the same make of plane/engine.
Haven't heard of similar incidents in the past really, but then I was not lokking for them either.
