I agree with most of the last few posts, - basically that is how it is.
Certainly the operator has to be factored in, - some are just too pushy or dare I say, even devious. Any suspicion of doctored oil consumption figures, secret filter changes, or otherwise 'economical with the truth' then it all stops.
It happens.
Some pilots are just hopeless also... the operators can be difficult customers.
What do you think the chances are of this character getting beyond TBO on his engine ?
