Narrative:

Contacted cgf ground control for taxi instructions to active runway. Completed engine run-up at taxiway at departure end of runway 23. WX was cold -- wearing gloves. Because of gloves, attempt to push communication button to switch from ground to tower was not accomplished. Called tower (on ground frequency) for takeoff clearance. Ground replied with a reminder to call tower. Then switched to tower, but was under the impression I had been cleared for takeoff. At same time there was some communications confusion due to communications from and to airplane behind me. This was compounded by tower frequency also used simultaneously with ground control. (This is a reason -- not an excuse). Assuming I had been cleared for takeoff (I heard what I expected to hear), I entered runway and prepared for takeoff. Tower then asked why I had done so without a clearance. For the first time I realized I had not been cleared and expressed my apologies. Tower then gave me a takeoff clearance. With all of the publicity about runway incursions, I should have been more alert even in the absence of inbound traffic.

Original NASA ASRS Text

Title: AN SMA PLT TAXIED INTO POS WITHOUT CLRNC AT CGF, OH.

Narrative: CONTACTED CGF GND CTL FOR TAXI INSTRUCTIONS TO ACTIVE RWY. COMPLETED ENG RUN-UP AT TXWY AT DEP END OF RWY 23. WX WAS COLD -- WEARING GLOVES. BECAUSE OF GLOVES, ATTEMPT TO PUSH COM BUTTON TO SWITCH FROM GND TO TWR WAS NOT ACCOMPLISHED. CALLED TWR (ON GND FREQ) FOR TKOF CLRNC. GND REPLIED WITH A REMINDER TO CALL TWR. THEN SWITCHED TO TWR, BUT WAS UNDER THE IMPRESSION I HAD BEEN CLRED FOR TKOF. AT SAME TIME THERE WAS SOME COMS CONFUSION DUE TO COMS FROM AND TO AIRPLANE BEHIND ME. THIS WAS COMPOUNDED BY TWR FREQ ALSO USED SIMULTANEOUSLY WITH GND CTL. (THIS IS A REASON -- NOT AN EXCUSE). ASSUMING I HAD BEEN CLRED FOR TKOF (I HEARD WHAT I EXPECTED TO HEAR), I ENTERED RWY AND PREPARED FOR TKOF. TWR THEN ASKED WHY I HAD DONE SO WITHOUT A CLRNC. FOR THE FIRST TIME I REALIZED I HAD NOT BEEN CLRED AND EXPRESSED MY APOLOGIES. TWR THEN GAVE ME A TKOF CLRNC. WITH ALL OF THE PUBLICITY ABOUT RWY INCURSIONS, I SHOULD HAVE BEEN MORE ALERT EVEN IN THE ABSENCE OF INBOUND TFC.
