A CANADAIR CL65 ON TKOF AT ROTATION DECLARED AN EMER AND DIVERTED DUE TO A 14TH STAGE DUCT WARNING CAUSED BY A 14TH STAGE DUCT LEAK.

Narrative

RIGHT AFTER ROTATION WE HAD A TRIPLE CHIME; A VISUAL WARNING; AND AN AUDIO WARNING. THE MESSAGE INFORMED US THAT WE HAD A RIGHT 14TH STAGE DUCT LEAK. AS THE PILOT FLYING; I TOLD THE CAPT THAT I WOULD FLY THE AIRPLANE AND HANDLE THE RADIOS WHILE HE PROCEEDED TO REVIEW THE APPROPRIATE CHKLIST. AFTER COMPLETING THE CHKLIST AND DETERMINING THAT THE MESSAGE WAS NOT OUT; THE CAPT ASSUMED CTL OF THE AIRPLANE AND ELECTED TO RETURN TO THE ARPT. THE CHKLIST SAID THAT IF THE MESSAGE FAILED TO GO OUT; TO SHUT DOWN THE ENG. RATHER THAN SHUT DOWN THE ENG AND CIRCLE FOR OVER AN HOUR TO BURN OFF THE NECESSARY FUEL; THE CAPT ELECTED TO RETURN IMMEDIATELY TO THE ARPT AND LAND OVER WT. I AGREED WITH THIS COURSE OF ACTION AND I PROCEEDED TO BRIEF THE FLIGHT ATTENDANT AND THE PAXS. WE TOLD THE TWR THAT WE WOULD LIKE TO RETURN TO THE ARPT; BUT WE DID NOT DECLARE AN EMER DUE TO THE FACT THAT EVERTHING WAS NORMAL OTHER THAN THAT THE MESSAGE.WE LANDED WITHOUT INCIDENT AND TAXIED TO THE GATE. THE ACFT WAS THEN TAKEN TO THE HANGER TO BE INSPECTED. DESPITE BEING A LITTLE RUSHED; I FEEL THE CAPT AND I WORKED THROUGH THE PROBLEM WELL AND WORKED TOGETHER AS A TEAM. THE TRAINING WE HAVE HAD CERTAINLY PAID OFF AND THIS IS A GOOD EXAMPLE OF HOW CRM WORKS. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE WARNING WAS AN ACTUAL 14TH STAGE DUCT LEAK AND NOT A FALSE WARNING. THE RPTR SAID THE ENG WAS NOT SHUT DOWN AS PER THE QUICK REFERENCE HANDBOOK PROCS.
