Narrative:

Upon reporting for duty the morning of aug/tue/95 for flight X from ashville to nashville, it was discovered that a hinge was broken on the nosewheel spade door. Maintenance was notified and removed the spade door, and signed the logbook off as ok for a ferry flight from avl to bna. A ferry permit was sent via the company computer to the station. The captain and I reviewed the permit for its limitations and consulted our flight manual part 1. We determined the flight would be operated under section 12 paragraph 12 -- special ferries and section 12 paragraph 11 -- ferry flts, special flight permit with continuing authority/authorized to conduct ferry flts. We received these requirements and were assured that they were met. Our IFR clearance for flight X was still active, so we elected to depart under that call sign. While we were airborne, dispatch informed us that a new release for Y was sent and we should have used that call sign. I was later debriefed upon arrival in nashville, that X was a revenue flight number and we should not have used that. The flight manual part 1 describing the rules and procedures, never states that the flight crew needs a new release with a new flight number, different from the originally scheduled flight number. I feel the flight manual should be revised to specifically state that a new release with a new flight number is required for ferry flts. This change would give the crew the information needed to prevent this from happening in the future.

Title: AN ACR ACFT WAS FLOWN ON A FERRY FLT, WITH A PROPER PERMIT, USING A REVENUE FLT CALL SIGN.

Narrative: UPON RPTING FOR DUTY THE MORNING OF AUG/TUE/95 FOR FLT X FROM ASHVILLE TO NASHVILLE, IT WAS DISCOVERED THAT A HINGE WAS BROKEN ON THE NOSEWHEEL SPADE DOOR. MAINT WAS NOTIFIED AND REMOVED THE SPADE DOOR, AND SIGNED THE LOGBOOK OFF AS OK FOR A FERRY FLT FROM AVL TO BNA. A FERRY PERMIT WAS SENT VIA THE COMPANY COMPUTER TO THE STATION. THE CAPT AND I REVIEWED THE PERMIT FOR ITS LIMITATIONS AND CONSULTED OUR FLT MANUAL PART 1. WE DETERMINED THE FLT WOULD BE OPERATED UNDER SECTION 12 PARAGRAPH 12 -- SPECIAL FERRIES AND SECTION 12 PARAGRAPH 11 -- FERRY FLTS, SPECIAL FLT PERMIT WITH CONTINUING AUTH TO CONDUCT FERRY FLTS. WE RECEIVED THESE REQUIREMENTS AND WERE ASSURED THAT THEY WERE MET. OUR IFR CLRNC FOR FLT X WAS STILL ACTIVE, SO WE ELECTED TO DEPART UNDER THAT CALL SIGN. WHILE WE WERE AIRBORNE, DISPATCH INFORMED US THAT A NEW RELEASE FOR Y WAS SENT AND WE SHOULD HAVE USED THAT CALL SIGN. I WAS LATER DEBRIEFED UPON ARR IN NASHVILLE, THAT X WAS A REVENUE FLT NUMBER AND WE SHOULD NOT HAVE USED THAT. THE FLT MANUAL PART 1 DESCRIBING THE RULES AND PROCS, NEVER STATES THAT THE FLC NEEDS A NEW RELEASE WITH A NEW FLT NUMBER, DIFFERENT FROM THE ORIGINALLY SCHEDULED FLT NUMBER. I FEEL THE FLT MANUAL SHOULD BE REVISED TO SPECIFICALLY STATE THAT A NEW RELEASE WITH A NEW FLT NUMBER IS REQUIRED FOR FERRY FLTS. THIS CHANGE WOULD GIVE THE CREW THE INFO NEEDED TO PREVENT THIS FROM HAPPENING IN THE FUTURE.
