EGT
Gentlemen,
I hesitate to comment unless I have reference to provide. In this case, I haven't the manuals with me.
However, as jet engines age, the "EGT Margin" reduces. At some point in the engine's life, it is, in fact, possible to slightly overtemp. This is normal.
Yes...what you just read is correct....to overtemp on takeoff is, in some cases and from an engineer's view point, 'normal'.
Again, this will occur when a jet engine ages. However, everything depends on by how much the EGT has been exceeded and for how long.
In some cases, e.g. slightly over the limit and for just a few moments, there will be no maintenance action necessary. In other cases, the engine may need to be changed.
There exist graphs showing all of this.
In all cases, the action demanded from the pilot is to follow SOP for EGT over limit.
Obviously, if engines overtemp on takeoff, they are due maintenance, overhaul, replacement...for that reason alone. This means that it's a tired engine, and it's due for some T.L.C. Not necessarily for the overtemp occurrance...but, for the reason the engines overtemp in the first place.
