Not 767 mate. The short 767 transits mean the compressor case doesn't cool down between flights. It is about the blade tip clearance.
Is this why no-one seems to be concerned with the EDTO effects of these engine failures?
Before you get upset with this question, I realize EDTO for B747 does not come into effect until 2015, however engine failures at an airline where that same engine is used on B767 twins, supposedly maintained to EDTO standards, it appears to me no-one is counting these failures in their IFSD rate calculations.
I would have thought they would have figured somewhere in their statistical analysis for EDTO. Are QANTAS still swapping engines between B767 and B747 like they used to many years ago?
