Carnage,
Agree. That's why I said "so-called expert" (he calls himself that in his "about me" section on his site.)
Found this little conversation about BA038 on a maintenance forum:
I believe it's the FADEC software update that was done recently. AA had the #2 engine not respond for about 15 seconds on one of their 777 with the same FADEC update code.
RR is looking into it...I wonder the directive for now is to use or rollback to the previous update.

I don't think it's one in a million odds anymore. I think dozens of fadec issues are well documented throughout the industry regardless of make. We were aware of rollbacks on both P&W and GE A310's when I flew that airplane back in the 90's. The solution was nearly always a new software "load."
There must be a FADEC code standard that is industry-wide prior to a powerplant being certified on a particular model. Where's Machaca? He's good at finding a needle in a haystack....
