Narrative:
After takeoff a vibration and noise from the right nose of aircraft was felt and heard. I realized this to be an open access door and as the PF, asked the first officer to ask the departure controller to sequence us for a return to the field. Shortly after this the 'stall fail' caution was observed intermittently, confirming to me that the oxygen service door was open and interfering with the airflow over the right stall vane. The appropriate checklists were accomplished and an uneventful return to the field. Upon taxi in the oxygen access door was observed in the spring loaded open (and up) position. The aircraft had come to the gate from the hangar where maintenance had been performed that night involving an oxygen service. Further examination revealed the oxygen door would stick in the down (closed) position with the 2 latches protruding open due to paint causing the door to stick.

Title: A CANADAIR CL65 WAS DISPATCHED IN NON COMPLIANCE WITH THE OXYGEN SVC DOOR CLOSED, BUT NOT LATCHED. ACFT RETURNED TO THE FIELD.
Narrative: AFTER TKOF A VIBRATION AND NOISE FROM THE R NOSE OF ACFT WAS FELT AND HEARD. I REALIZED THIS TO BE AN OPEN ACCESS DOOR AND AS THE PF, ASKED THE FO TO ASK THE DEP CTLR TO SEQUENCE US FOR A RETURN TO THE FIELD. SHORTLY AFTER THIS THE 'STALL FAIL' CAUTION WAS OBSERVED INTERMITTENTLY, CONFIRMING TO ME THAT THE OXYGEN SVC DOOR WAS OPEN AND INTERFERING WITH THE AIRFLOW OVER THE R STALL VANE. THE APPROPRIATE CHKLISTS WERE ACCOMPLISHED AND AN UNEVENTFUL RETURN TO THE FIELD. UPON TAXI IN THE OXYGEN ACCESS DOOR WAS OBSERVED IN THE SPRING LOADED OPEN (AND UP) POS. THE ACFT HAD COME TO THE GATE FROM THE HANGAR WHERE MAINT HAD BEEN PERFORMED THAT NIGHT INVOLVING AN OXYGEN SVC. FURTHER EXAMINATION REVEALED THE OXYGEN DOOR WOULD STICK IN THE DOWN (CLOSED) POS WITH THE 2 LATCHES PROTRUDING OPEN DUE TO PAINT CAUSING THE DOOR TO STICK.
