Narrative:

After turning off active runway 27 upon completion of an ILS, I did not receive any instructions from tower relating to contact ground control. I changed to ground control frequency 121.9. At the time of setting in ground control, I heard 'taxi to the ramp' which we frequently hear since this is our home base and have frequent ground control contact. No other aircraft were observed taxiing on airport. When almost to parking ramp, ground control called and stated I had not contacted ground control. I stated I had thought I had heard 'taxi to the ramp.' controller advised I was the only ground operation and no such instructions had been given. I apologized for the misunderstanding and no additional conversation occurred. Our frequent operations at our home airport at all times of the day, coupled with many less than formal radio communications can tend to lead to complacency on the part of both pilots and controllers. Since I was the only aircraft movement on the airport, and if the ground controller believed no taxi clearance had been given, why would he let me taxi all the way to the ramp and call me about it just before shut down? I feel pilots and controllers need to help each other and thus contribute to an improved climate of safety.

Title: LNDG SMT TAXIES WITHOUT CLRNC FROM GND CTL.

Narrative: AFTER TURNING OFF ACTIVE RWY 27 UPON COMPLETION OF AN ILS, I DID NOT RECEIVE ANY INSTRUCTIONS FROM TWR RELATING TO CONTACT GND CTL. I CHANGED TO GND CTL FREQ 121.9. AT THE TIME OF SETTING IN GND CTL, I HEARD 'TAXI TO THE RAMP' WHICH WE FREQUENTLY HEAR SINCE THIS IS OUR HOME BASE AND HAVE FREQUENT GND CTL CONTACT. NO OTHER ACFT WERE OBSERVED TAXIING ON ARPT. WHEN ALMOST TO PARKING RAMP, GND CTL CALLED AND STATED I HAD NOT CONTACTED GND CTL. I STATED I HAD THOUGHT I HAD HEARD 'TAXI TO THE RAMP.' CTLR ADVISED I WAS THE ONLY GND OP AND NO SUCH INSTRUCTIONS HAD BEEN GIVEN. I APOLOGIZED FOR THE MISUNDERSTANDING AND NO ADDITIONAL CONVERSATION OCCURRED. OUR FREQUENT OPS AT OUR HOME ARPT AT ALL TIMES OF THE DAY, COUPLED WITH MANY LESS THAN FORMAL RADIO COMS CAN TEND TO LEAD TO COMPLACENCY ON THE PART OF BOTH PLTS AND CTLRS. SINCE I WAS THE ONLY ACFT MOVEMENT ON THE ARPT, AND IF THE GND CTLR BELIEVED NO TAXI CLRNC HAD BEEN GIVEN, WHY WOULD HE LET ME TAXI ALL THE WAY TO THE RAMP AND CALL ME ABOUT IT JUST BEFORE SHUT DOWN? I FEEL PLTS AND CTLRS NEED TO HELP EACH OTHER AND THUS CONTRIBUTE TO AN IMPROVED CLIMATE OF SAFETY.
