A CANADAIR CL65 WAS DISPATCHED ON A MAINT FERRY IN NON COMPLIANCE WITHOUT THE MANDATORY LOGBOOK ENTRIES.

Narrative

THE CREW RPTED APPROX XA20 FOR AN XB00 DEP. WHILE THE FO PREFLTED THE EXTERIOR OF THE ACFT; I PERFORMED THE FIRST FLT OF THE DAY SYS TEST IN THE COCKPIT AND LOOKED OVER THE ACFT PAPERWORK INCLUDING THE MAINT LOGBOOKS. I NOTICED THAT THE MAINT DISCREPANCY LOGBOOK HAD A COUPLE OF FRESH WRITE-UPS BUT THERE WAS NOT AN 'OPEN' WRITE-UP (DISCREPANCY WITHOUT CORRECTIVE ACTION COMPLETED). THE MOST RECENT WRITE-UP STATED; 'FO'S OXYGEN MASK DOES NOT TEST PROPERLY.' WHEN QUESTIONED; THE FO SAID HIS MASK TESTED AND HE PERFORMED THE TEST AGAIN. IT DID SEEM TO TEST PROPERLY; HOWEVER; I DID NOT GET OUT OF MY SEAT AND OBSERVE THE UNIT WHILE BEING TESTED (AND I'M NOT REQUIRED TO DO THAT). FLTS TO YUL AND BACK TO ZZZ WERE CONDUCTED UNEVENTFULLY. DURING PREPARATION FOR ANOTHER ROUND-TRIP; I HAPPENED TO CALL MAINT CTL IN XXX ABOUT A CAUTION MESSAGE THAT WE WERE ABLE TO CLR DURING THE FIRST TAXI OUT THAT MORNING. THEY THEN INFORMED ME THERE WAS A PROB WITH THE ACFT. THE ACFT HAD BEEN FERRIED THE NIGHT BEFORE AND LEFT SITTING AT THE GATE NOT REPAIRED; BUT WITH NO OPEN WRITE-UP. MAINT CTL FAILED TO NOTIFY THE CREW AT SEVERAL OPPORTUNITIES. DISPATCH WAS UNAWARE OF THE PROB SINCE WE WERE DISPATCHED 3 TIMES. LCL MAINT DIDN'T COME TO THE ACFT UNTIL WE CALLED THEM AND THEY SAID CVG MAINT TOLD THEM NOT TO GOING TO THE ACFT UNTIL THE PART ARRIVED (WHICH WAS LATE). I FEEL THEY SHOULD HAVE AT LEAST TAKEN THE MAINT LOGS OUT OF THE ACFT. BEFORE THE FLT EVER DEPARTED; ZZZ MAINT WAS CONTACTED BY CELL PHONE REGARDING THE CAUTION AND THEY SAID NOTHING ABOUT A PROB WITH THE ACFT. NO ONE CONTACTED US IN YUL; IN THE AIR; OR UPON RETURN TO ZZZ.
