Narrative:

On a visual into daytona beach, I remember us being cleared for the visual approach by the final controller. On final, I asked the captain if we were cleared to land. He said we were. I do not recall a radio exchange between us and the tower. After landing on rollout, the captain took the airplane and we turned off the runway. I looked to tune the radios to ground and I noticed that one was on dab approach and the other was tuned to ground. When I asked the captain about this, he said he must have tuned ground into the radio that tower had been tuned to after landing clearance. This would have left the other radio tuned to approach. The fact that neither radio was tuned to tower, and that I don't recall any exchange between us, makes me think we landed without a clearance. However, the ground controller never indicated anything was wrong when we contacted him.

Title: LNDG WITHOUT CLRNC FROM TWR.

Narrative: ON A VISUAL INTO DAYTONA BEACH, I REMEMBER US BEING CLRED FOR THE VISUAL APCH BY THE FINAL CTLR. ON FINAL, I ASKED THE CAPT IF WE WERE CLRED TO LAND. HE SAID WE WERE. I DO NOT RECALL A RADIO EXCHANGE BTWN US AND THE TWR. AFTER LNDG ON ROLLOUT, THE CAPT TOOK THE AIRPLANE AND WE TURNED OFF THE RWY. I LOOKED TO TUNE THE RADIOS TO GND AND I NOTICED THAT ONE WAS ON DAB APCH AND THE OTHER WAS TUNED TO GND. WHEN I ASKED THE CAPT ABOUT THIS, HE SAID HE MUST HAVE TUNED GND INTO THE RADIO THAT TWR HAD BEEN TUNED TO AFTER LNDG CLRNC. THIS WOULD HAVE LEFT THE OTHER RADIO TUNED TO APCH. THE FACT THAT NEITHER RADIO WAS TUNED TO TWR, AND THAT I DON'T RECALL ANY EXCHANGE BTWN US, MAKES ME THINK WE LANDED WITHOUT A CLRNC. HOWEVER, THE GND CTLR NEVER INDICATED ANYTHING WAS WRONG WHEN WE CONTACTED HIM.
