PLT OF SMA RECEIVED INFLT CLRNC ON TKOF ROLL AT ALS; FAILED TO HOLD AT VOR PER CLRNC.

Narrative

I CALLED FOR MY IFR CLRNC FROM THE GND AT THE UNCTLED ARPT IN ALAMOSA; CO; AND WAS TOLD TO EXPECT MY CLRNC IN APPROX 1 MIN. I ELECTED TO BEGIN THE FLT AND REMAIN VFR UNTIL THE CLRNC WAS RECEIVED TO IMPROVE RADIO RECEPTION. WITHIN 300 FT OF TKOF ROLL; CENTER CALLED WITH THE CLRNC. MY SON (PRIVATE PLT; NON INST RATED; 95 HRS TOTAL TIME) WROTE DOWN THE CLRNC; 'CLRED TO THE ALAMOSA VORTAC; CLB AND MAINTAIN 13000; CALL DEPARTING ALAMOSA'. I READ BACK THE CLRNC AND ANNOUNCED OFF OF ALAMOSA. CENTER ASKED ME TO SAY AGAIN AND I REPEATED MY CALL. THEY DID NOT ACKNOWLEDGE I WAS OFF ALAMOSA. THE VORTAC IS ONLY 5.2 NM FROM THE ARPT AND THERE WERE NO HOLDING INSTRUCTIONS PROVIDED. I WAS PREOCCUPIED BY A RED LINE OIL TEMP GAUGE. I WAS MAINTAINING A STEEP ANGLE OF CLB TO REACH ALT QUICKLY SINCE WE WERE IN THE CLOUDS IN MOUNTAINOUS TERRAIN. UPON PASSING THE VOR I TURNED SLIGHTLY L TO JOIN V83; MY FLT PLAN RTE. CENTER CALLED FOR MY POS; REMINDED ME I WAS CLRED ONLY TO THE VORTAC AND GAVE ME AN IMMEDIATE R TURN TO 240 DEG FOR SEPARATION FROM TFC ABOVE ME AT 13500. THE CTLR ASKED ME WHY I DID NOT CALL OFF. I WAS CLRED TO CONTINUE TO COLORADO SPRINGS VIA FLT PLAN RTE. CORRECTIVE ACTIONS: FROM THE PLT'S PERSPECTIVE; I SHOULD HAVE WAITED ON THE GND FOR MY CLRNC. THERE WAS NO REASON TO HURRY. UPON XING THE VOR; I SHOULD HAVE NOTIFIED CENTER OF MY POS AND THEY WOULD HAVE ISSUED INSTRUCTIONS. I SHOULD HAVE CHALLENGED THE CLRNC GIVEN THE EXTREMELY SHORT DISTANCE AND ASKED FOR INSTRUCTIONS AND EXPECT FURTHER CLRNC TIME. LASTLY; I SHOULD HAVE REQUESTED ACKNOWLEDGEMENT FROM CENTER THAT I WAS OFF THE GND. FROM THE CTLR'S PERSPECTIVE; A CLRNC PROBABLY SHOULD NOT HAVE BEEN ISSUED WITH A LIMIT SO CLOSE TO THE ARPT. SINCE IT WAS ISSUED (AND ACCEPTED) IT SHOULD HAVE INCLUDED INSTRUCTIONS AT THE CLRNC LIMIT. THE CTLR SHOULD HAVE ACKNOWLEDGED THE PLT'S CALL OFF ALAMOSA (THE CALL WAS REPEATED TWICE).
