Narrative:

On feb/sat/00, I was on a scheduled IFR 135, from bna. I had been on the ground, a layover for 9 hours, and was quite tired. I contacted ground and taxied to runway 2C. When I was ready I called the tower and stated that I was ready for takeoff. The traffic volume was quite high. The tower said taxi up to the hold short line. I understood taxi in position and hold. With all the traffic, I misheard, and I read back 'roger', but before I completed the transmission, I realized my key had disengaged in the middle of transmission. I realized something was wrong about 15 seconds later. By then I was on the runway and an airliner had to go around. That incursion was probably due to fatigue, confusion, traffic volume.

Title: A C210 ATX PLT CREATES A RWY INCURSION WHEN HE IS CONFUSED BY THE TFC VOLUME AND FATIGUE FROM A 'STAND UP' LAYOVER AT BNA, TN.

Narrative: ON FEB/SAT/00, I WAS ON A SCHEDULED IFR 135, FROM BNA. I HAD BEEN ON THE GND, A LAYOVER FOR 9 HRS, AND WAS QUITE TIRED. I CONTACTED GND AND TAXIED TO RWY 2C. WHEN I WAS READY I CALLED THE TWR AND STATED THAT I WAS READY FOR TKOF. THE TFC VOLUME WAS QUITE HIGH. THE TWR SAID TAXI UP TO THE HOLD SHORT LINE. I UNDERSTOOD TAXI IN POS AND HOLD. WITH ALL THE TFC, I MISHEARD, AND I READ BACK 'ROGER', BUT BEFORE I COMPLETED THE XMISSION, I REALIZED MY KEY HAD DISENGAGED IN THE MIDDLE OF XMISSION. I REALIZED SOMETHING WAS WRONG ABOUT 15 SECONDS LATER. BY THEN I WAS ON THE RWY AND AN AIRLINER HAD TO GO AROUND. THAT INCURSION WAS PROBABLY DUE TO FATIGUE, CONFUSION, TFC VOLUME.
