The following list, found online (and thus likely fake, but funny anyways), is apparently from Qantas airlines. The story goes like this: after flights pilots fill out gripe sheets listing complaints, mechanics obtain these sheets and repair the problems, then indicate how the problem was fixed and the status. The report is available to the pilot of a plane before he takes off. Even if they’re not true they’re still kinda funny:

(P = The problem logged by the pilot.)
(S = The solution and action taken by the engineer.)
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: Auto-land 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: Autopilot in altitude-hold mode produces a 200 feet-per-minute descent.
S: Cannot reproduce problem on ground.
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 they’re there for.
P: IFF inoperative.
S: IFF always 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.
P: Aircraft handles funny.
S: Aircraft warned to straighten up, fly right, and be serious.
P: Target radar hums.
S: Reprogrammed target radar with lyrics.
P: Mouse in cockpit.
S: Cat installed.
P: Noise coming from under instrument panel. Sounds like a midget pounding on something with a hammer.
S: Took hammer away from midget.
