.... and the one in LHR is very much RR related too.
Too?
RR & EASA are doing the right thing - fuel oil heat exchanger has been redesigned and EASA has mandated replacement (AD2009-0142 13 July 2009).
I concurr that between AF and other european carriers there is a gap and that within AF the incident rate between Airbus and the 777 (now talking only fbw aircraft) is quite apparent ....
Would be interested if you know of any evidence on the Airbus vs 777 incident rate within AF.
