well i'll take my 18 years of experience and bet it against the best of the world.:beach:
As for my CEO of absolutely nothing comes from an Absolut a commercial.
Most engines if they have a "fire" when they are taking off would indicate that there is a compression stall induced when the variable guide vanes are not working properly e.g. not in rig. Something usually moves them this way. This comes from only one source the Fuel Pump or the Mechanical Fuel Control, sometimes FADEC run, the MFC usually schedules the VG in two ways, through linkage that is run off the MFC, or though a Linear Variable Actuator that runs those bad boys.
Most people think that engines just "blow up". This is far from true, there are several indicators that an engine is about to "blow up" G.E. usually refers to these as "events" which is very funny to me, because they did not like my PC of the whole matter when my Engine "blew up". The EGT will be unusually high or take a spike. When the EGT and the fan speeds up this is an indication of a LPT failure, or a fan disk crack, which is very bad. When your VG is out of rig, or very slightly out of rig, your idle EGT will be quite high, and you get very funny fluctuations on start, sometimes indicated by spikes when going through about 35-50 % N2 just after fuel is added.
A fire is more of when an engine has abrupt flames outside of the "combustion" area.
However if the engine is still making power, or even looses power most pilots are trained to handle this on takeoff, so my vote goes to pilot error.
And the comment comes from the world reporting section, not from the forum, but you can take it however you want.
