After every flight, Qantas pilots fill out a form called a "gripe sheet," which tells mechanics about problems with the aircraft. The mechanics correct the problems; document their repairs on the form, and then pilots review the gripe sheets before the next flight. Never let it be said that ground crews lack a sense of humor. Here are some actual maintenance complaints submitted by Qantas' pilots (marked with a P) and the solutions recorded (marked with an S) by maintenance engineers. By the way, Qantas is the only major airline that has never had an accident....Enjoy! P: Left inside main tire almost needs replacement.
