Narrative:

Crew awoke at XA45 am, left hotel in ZZZ at XB45 am for an XC40 flight to atl. I (first officer) performed a security check (standard procedure for an aircraft on first flight of operational day) which involved opening the oxygen service door just forward of the right pitot tube. During the takeoff, the EICAS indicated a stall fail caution message. (This is classified as a nuisance message, and normal procedure is to continue.) as airspeed increased, crew heard a loud rushing sound from the right side of the aircraft. The crew decided to return for landing and have the door checked. The captain elected to hand-fly the aircraft. While we were completing required checklists, I observed an altitude deviation approximately 600 ft above cleared altitude, which was immediately corrected. The crew briefed landing above the 47000 pound maximum landing weight, and returned to ZZZ. After landing, entries were made in the aircraft maintenance log for overweight landing and door open in-flight. Inspections found no damage or discrepancies. The thumb-latches on this door can appear closed when they are not latched. Better security could prevent occurrence.

Title: A CANADAIR CL600 ON CLBOUT AT 3000 FT RETURNED TO LAND DUE TO STALL FAIL EICAS MESSAGE AND LOUD AIR RUSHING NOISE FROM ACFT R SIDE.

Narrative: CREW AWOKE AT XA45 AM, LEFT HOTEL IN ZZZ AT XB45 AM FOR AN XC40 FLT TO ATL. I (FO) PERFORMED A SECURITY CHK (STANDARD PROC FOR AN ACFT ON FIRST FLT OF OPERATIONAL DAY) WHICH INVOLVED OPENING THE OXYGEN SVC DOOR JUST FORWARD OF THE R PITOT TUBE. DURING THE TKOF, THE EICAS INDICATED A STALL FAIL CAUTION MESSAGE. (THIS IS CLASSIFIED AS A NUISANCE MESSAGE, AND NORMAL PROC IS TO CONTINUE.) AS AIRSPD INCREASED, CREW HEARD A LOUD RUSHING SOUND FROM THE R SIDE OF THE ACFT. THE CREW DECIDED TO RETURN FOR LNDG AND HAVE THE DOOR CHKED. THE CAPT ELECTED TO HAND-FLY THE ACFT. WHILE WE WERE COMPLETING REQUIRED CHKLISTS, I OBSERVED AN ALTDEV APPROX 600 FT ABOVE CLRED ALT, WHICH WAS IMMEDIATELY CORRECTED. THE CREW BRIEFED LNDG ABOVE THE 47000 LB MAX LNDG WT, AND RETURNED TO ZZZ. AFTER LNDG, ENTRIES WERE MADE IN THE ACFT MAINT LOG FOR OVERWT LNDG AND DOOR OPEN INFLT. INSPECTIONS FOUND NO DAMAGE OR DISCREPANCIES. THE THUMB-LATCHES ON THIS DOOR CAN APPEAR CLOSED WHEN THEY ARE NOT LATCHED. BETTER SECURITY COULD PREVENT OCCURRENCE.
