We had an engine blank go 'missing' a while ago.
The company had to buy, not just the missing rear blank, but a whole set, as they aren't sold individually
.
It was a couple of hundred pounds IIRC, for a Citation jet.
On another note, just ignore certain, idiotic people on this forum (a Bl**ddy SPOTTERS FORUM), as they are probably sad individuals who like to raise their own, sad, insignificant importance.
As a pilot, I always wave at the spotters and look out for said piccys on the various websites. A much better hobby than stamp collecting!
