Narrative:

As the captain of this scheduled part 121 flight, I completed my preflight, which included an inspection and review of the aircraft logbook. Everything appeared normal, included an airworthiness released which had been recorded 2 or 3 days earlier. I noted the airplane had been ferried due to some minor maintenance which had been performed. I failed to remember that ferry flts for maintenance related purposes required a new airworthiness release. We flew the airplane uneventfully, as did 9 other air crews since the ferry flight. Another company pilot caught the discrepancy a day or two later, and brought it to the attention of our company maintenance department. Maintenance then signed off a new airworthiness release. The company pilot who caught the discrepancy called me and told me about it on oct/mon/00. I could have prevented this oversight by having better knowledge of the requirements for an airworthy airplane. Even though I had been made aware of the maintenance/ferry flight requirement in the past, I did not correctly apply this rule to my logbook inspection. The fact that our company maintenance failed to record the release is no excuse for my oversight.

Title: FLC OF AN LGT OPERATED ACFT WITHOUT CURRENT MAINT FLT RELEASE AFTER A MAINT FERRY FLT.

Narrative: AS THE CAPT OF THIS SCHEDULED PART 121 FLT, I COMPLETED MY PREFLT, WHICH INCLUDED AN INSPECTION AND REVIEW OF THE ACFT LOGBOOK. EVERYTHING APPEARED NORMAL, INCLUDED AN AIRWORTHINESS RELEASED WHICH HAD BEEN RECORDED 2 OR 3 DAYS EARLIER. I NOTED THE AIRPLANE HAD BEEN FERRIED DUE TO SOME MINOR MAINT WHICH HAD BEEN PERFORMED. I FAILED TO REMEMBER THAT FERRY FLTS FOR MAINT RELATED PURPOSES REQUIRED A NEW AIRWORTHINESS RELEASE. WE FLEW THE AIRPLANE UNEVENTFULLY, AS DID 9 OTHER AIR CREWS SINCE THE FERRY FLT. ANOTHER COMPANY PLT CAUGHT THE DISCREPANCY A DAY OR TWO LATER, AND BROUGHT IT TO THE ATTN OF OUR COMPANY MAINT DEPT. MAINT THEN SIGNED OFF A NEW AIRWORTHINESS RELEASE. THE COMPANY PLT WHO CAUGHT THE DISCREPANCY CALLED ME AND TOLD ME ABOUT IT ON OCT/MON/00. I COULD HAVE PREVENTED THIS OVERSIGHT BY HAVING BETTER KNOWLEDGE OF THE REQUIREMENTS FOR AN AIRWORTHY AIRPLANE. EVEN THOUGH I HAD BEEN MADE AWARE OF THE MAINT/FERRY FLT REQUIREMENT IN THE PAST, I DID NOT CORRECTLY APPLY THIS RULE TO MY LOGBOOK INSPECTION. THE FACT THAT OUR COMPANY MAINT FAILED TO RECORD THE RELEASE IS NO EXCUSE FOR MY OVERSIGHT.
