Narrative:

I do not have a clear recollection of obtaining a clearance to taxi for departure at controller in charge on feb/xa/01. Shortly after leaving the air traffic area, having received a clearance for departure, I could not remember having called chico ground control for taxi instructions prior to taxiing to runway 13L. At no time was there an incursion or unsafe condition. As a matter of fact, the tower never made any comment to me, so it is possible that I did get taxi instructions, but simply forgot that I did. If true, the contributing factor would be preoccupation with complexity of forthcoming long VFR/IFR flight to las. At the time I was well rested, alert and not under the influence of the head cold sweeping through my family.

Original NASA ASRS Text

Title: SMA PLT CANNOT REMEMBER AFTER TKOF IF HE OBTAINED TAXI CLRNC FOR TKOF.

Narrative: I DO NOT HAVE A CLR RECOLLECTION OF OBTAINING A CLRNC TO TAXI FOR DEP AT CIC ON FEB/XA/01. SHORTLY AFTER LEAVING THE ATA, HAVING RECEIVED A CLRNC FOR DEP, I COULD NOT REMEMBER HAVING CALLED CHICO GND CTL FOR TAXI INSTRUCTIONS PRIOR TO TAXIING TO RWY 13L. AT NO TIME WAS THERE AN INCURSION OR UNSAFE CONDITION. AS A MATTER OF FACT, THE TWR NEVER MADE ANY COMMENT TO ME, SO IT IS POSSIBLE THAT I DID GET TAXI INSTRUCTIONS, BUT SIMPLY FORGOT THAT I DID. IF TRUE, THE CONTRIBUTING FACTOR WOULD BE PREOCCUPATION WITH COMPLEXITY OF FORTHCOMING LONG VFR/IFR FLT TO LAS. AT THE TIME I WAS WELL RESTED, ALERT AND NOT UNDER THE INFLUENCE OF THE HEAD COLD SWEEPING THROUGH MY FAMILY.
