Lauda Air Flight 004
First Officer Thurner asked if he should contact the Lauda maintenance crew in Bangkok, and the captain reassured him, saying that it was "just an advisory thing", and that there was "just water, or moisture in there", and moved on; the first officer shortly thereafter tells the captain that the aircraft needs "a little bit of rudder trim to the left". Over the next few minutes, the aircraft continued on its filed flight plan while climbing to FL310.
