Narrative:
After takeoff on runway 27, a loud noise was heard coming from front area of aircraft. For a while, I (and crew) thought it was the air driven generator that deployed from right nose of aircraft. Upon further troubleshooting, found that the air driven generator could not have deployed due to absence of icons and messages on the EICAS system. We immediately returned to the airport for an uneventful landing. Further examination at the gate showed the oxygen access panel popped open after takeoff causing the noise. Prior to flight, the normal preflight showed no ajar or open panels on the aircraft. Moderate turbulence was encountered after takeoff due to strong xwinds and LLWS advisories in effect.

Title: A CANADAIR CL65 ON INITIAL CLB AT 1500 FT DIVERTED DUE TO A LOUD NOISE FROM THE NOSE OF THE ACFT CAUSED BY THE OXYGEN SVC DOOR COMING OPEN.
Narrative: AFTER TKOF ON RWY 27, A LOUD NOISE WAS HEARD COMING FROM FRONT AREA OF ACFT. FOR A WHILE, I (AND CREW) THOUGHT IT WAS THE AIR DRIVEN GENERATOR THAT DEPLOYED FROM R NOSE OF ACFT. UPON FURTHER TROUBLESHOOTING, FOUND THAT THE AIR DRIVEN GENERATOR COULD NOT HAVE DEPLOYED DUE TO ABSENCE OF ICONS AND MESSAGES ON THE EICAS SYS. WE IMMEDIATELY RETURNED TO THE ARPT FOR AN UNEVENTFUL LNDG. FURTHER EXAMINATION AT THE GATE SHOWED THE OXYGEN ACCESS PANEL POPPED OPEN AFTER TKOF CAUSING THE NOISE. PRIOR TO FLT, THE NORMAL PREFLT SHOWED NO AJAR OR OPEN PANELS ON THE ACFT. MODERATE TURB WAS ENCOUNTERED AFTER TKOF DUE TO STRONG XWINDS AND LLWS ADVISORIES IN EFFECT.
