I wrote in the tech log of a 212 "failed power assurance check", and with the open entry still in the book a kiwi pilot thought nothing of then taking it out and doing a job for a customer. It was incomprehensible for him to think that it might need maintenance before the next flight. Or at least for the open entry to be deferred by the mechanic. I used to see a lot (and I mean a lot) of that sort of stuff from kiwi pilots.
