At the end of every flight, the pilots for Qantas fill in what is called a 'gripe' sheet where they write any faults they found on the aircraft during the flight, which is then handed to ground maintenance who rectify the faults and write a report so the pilot can see what exactly has been done. This is a copy of an actual 'gripe' sheet. Never let it be said engineers don't have a sense of humour.....
