Narrative:

After landing (straight-in) at bda, tower advised that we had not been cleared to land. I remember calling tower but I am not sure if there was a response. We had been cleared for a straight-in visual and there were no other aircraft in the air or taxiing, so we may have been too complacent about a clearance. Also, crew was slightly distracted by other chores. I think this was a basic lapse in cockpit discipline and fatigue. We had flown a 12 hour day then a 10 1/2 hour day with a minimum rest period and an early departure. This flight had been routine and there was no other radio conversation, so listening for other traffic required no attention. Complacency and fatigue allowed a lapse that should not have occurred.

Original NASA ASRS Text

Title: FLC OF AN LGT ACR ACFT LANDED WITHOUT CLRNC.

Narrative: AFTER LNDG (STRAIGHT-IN) AT BDA, TWR ADVISED THAT WE HAD NOT BEEN CLRED TO LAND. I REMEMBER CALLING TWR BUT I AM NOT SURE IF THERE WAS A RESPONSE. WE HAD BEEN CLRED FOR A STRAIGHT-IN VISUAL AND THERE WERE NO OTHER ACFT IN THE AIR OR TAXIING, SO WE MAY HAVE BEEN TOO COMPLACENT ABOUT A CLRNC. ALSO, CREW WAS SLIGHTLY DISTRACTED BY OTHER CHORES. I THINK THIS WAS A BASIC LAPSE IN COCKPIT DISCIPLINE AND FATIGUE. WE HAD FLOWN A 12 HR DAY THEN A 10 1/2 HR DAY WITH A MINIMUM REST PERIOD AND AN EARLY DEP. THIS FLT HAD BEEN ROUTINE AND THERE WAS NO OTHER RADIO CONVERSATION, SO LISTENING FOR OTHER TFC REQUIRED NO ATTN. COMPLACENCY AND FATIGUE ALLOWED A LAPSE THAT SHOULD NOT HAVE OCCURRED.
