I read the article....nothing special about the incidents.
If you saw the statistics, you'd notice that these are not unusual, in the industry....but, because of the Qantas incidents recently, each time it
happens to
one airline, it gets hyped to the max.
Delta 30, JFK to Moscow, was apparently most serious, with a confirmed "power loss". (That is the proper call-out, at least where I flew).
The other two, in the article, were vague...I could look them up for you. Any number of situations can crop up, not always a sudden loss of power,
either.
Some years ago, in a B-757, we had an overtemp warning (Not in the engine itself, part of the pneumatic system, which uses hot compressed airflow
tapped from the engine, at various stages, for various purposes. Primarily, pressurization). Followed procedure, which was first to retard throttle
to idle power. IF the overheat light extinguished, then could continue with engine operating at the power setting that kept the light off. Of course
since we were going from New York to Quito, and we had just left, there was no doubt but a return for landing.
As it turned out, the hot air leak was in a location that didn't extinguish, with engine at idle, so the procedure then was a precautionary
shut-down.
I didn't tell the passengers this, just an "engine problem" and we diverted into Washington Dulles (closest, at that time). They didn't need to
worry, about only having the one engine. My crew knew, though, of course....
This never made it to the media, of course. Was a non-event. BUT, it gets written up, a Captain's Report is filed, copies are kept by the Company,
copies go to the FAA, to Boeing, to Rolls Royce (manufacturer of the engine), and the actual fault (once maintenance gets to it, on the ground) is all
documented. Stays in the industry, as data-sets for future reference, should anything re-cur, or to look for trends....
