Apologies if this has been posted before.
After every flight, pilots fill out a form called a gripe sheet, which conveys to the mechanics and other ground crew any problems encountered with the aircraft during the flight that need repair or correction. The mechanics/ground crew read and correct the problem, and then respond in writing on the lower half of the form what remedial action was taken. The pilot reviews the gripe sheets before the next flight. Never let it be said that ground crews and engineers lack a sense of humour. Here are some actual logged maintenance complaints and problems as submitted by pilots and the solution recorded by maintenance engineers.
(P = the problem logged by the pilot.)
(S = the solution and action taken by the engineers or ground crew.)
