NOSE DOOR OPEN  RED CAS: ON DEPARTURE AFTER GEAR SLECTED UP WE RECIEVED A " NOSE DOOR OPEN " RED CAS MESSAGE SHORTLY THERE AFTER WE GOT THE " GEAR DISAGREE " RED CAS MESSAGE.

GAVE THE SYSTEM AN HOUR TO COOL AND PERFORMED ANOTHER 7 SWINGS WITHOUT FAULT. ALL OPS AND LEAK CHECKS GOOD AT THIS TIME. REF AMM 32-33-07.
