Sort of reminded me of this, that was going round the Internet a few years ago? 
This was posted back in 2006 on FlightAware. Apparently, UPS pilots fill out a form known as a “gripe sheet” to inform mechanics about problems with their aircraft. The mechanics then correct the problems, document their repairs on the form and the pilots review the gripe sheets before the next flight.
Hence, here are some actual maintenance complaints submitted by pilots (marked with a P) and the solutions recorded (marked with an S) by maintenance engineers (and who says that aviation mechanics do not have a sense of humour!):
P: Left inside main tire almost needs replacement.
S: Almost replaced left inside main tire.
*
P: Test flight OK, except auto-land very rough.
S: Probably because auto-land is not installed on this aircraft.
*
P: Something loose in cockpit
S: Something tightened in cockpit

P: Dead bugs on windshield.
S: Live bugs on back-order.

P: Evidence of leak on right main landing gear.
S: Evidence removed.
*
P: DME volume unbelievably loud.
S: DME volume set to more believable level.

P: Friction locks cause throttle levers to stick.
S: That’s what friction locks are for.
*
P: IFF inoperative in OFF mode.
S: IFF IS inoperative in OFF mode.
*
P: Suspected crack in windshield.
S: Suspect you’re right.
*
P: Number 3 engine missing.
S: Engine found on right wing after brief search.
*
PS: Aircraft acting funny
S: Aircraft warned to straighten up, fly right and be serious.
*
P: Target radar hums.
S: Reprogrammed target radar with lyrics.

And the best one for last
