Narrative:

Landed runway 16 eug, turned off active on taxiway that led across runway 21. I have landed eug over 1000 times in 10 yrs. I know I need clearance to cross runway 21. I'm on taxiway moving very slowly. I notice small aircraft Y holding in position on 21. I tell tower I'm clear active. I'm waiting for roger zzw, go to ground point 7. No answer. I hear, 'zw (squeak) 7 (squawk) ter 21.' I add power to cross 21 as the small aircraft Y is still holding on 21 and I read back 'zzw clear to cross 21, contact ground after crossing' to be sure I heard correctly. Tower supervisor calls and says, 'zww stop right now, hold short 21.' I apply brakes and slide tires about 8' and stop 2' past holding line. Small aircraft Y on 21 still holding. I was told to go to ground .7. I do and contact ground and report holding 21. The small aircraft Y takes off. I'm cleared across to parking and informed to talk to tower supervisor on phone waiting as I deplaned. I talked to the supervisor. I said I would not have crossed if small aircraft Y had been moving and I thought I was cleared to cross. He said I never was and he heard everything, and I said my radio may have malfunctioned. He said it was almost a violation and a disaster. I told him again if the small aircraft Y 1500' away on 21 had been moving I would not have crossed and would have radio checked. Later on ground frequency #2 radio didn't seem to work correctly on 121.7, vol screw loose. Contributing factors: early as independence FBO said he didn't hear me when I landed, ground check radios worked. Eug area--new tower controller--very busy--accent and hard to understand. Airplane eug similar numbers: ##zax. Communication problem. Also training controllers at eug and a lot of students eug. I'm not sure exactly what happened to cause this incident. I do know it has never happened before and I know it won't happen again because I will be sure I have positive full number clearance and readback and not move until I am sure I do have clearance, and I'll also be sure way is clear regardless of clearance. Helluva way to treat brand new tires.

Title: NEAR RWY INCURSION BY TAXIING GA SMA.

Narrative: LANDED RWY 16 EUG, TURNED OFF ACTIVE ON TXWY THAT LED ACROSS RWY 21. I HAVE LANDED EUG OVER 1000 TIMES IN 10 YRS. I KNOW I NEED CLRNC TO CROSS RWY 21. I'M ON TXWY MOVING VERY SLOWLY. I NOTICE SMA Y HOLDING IN POS ON 21. I TELL TWR I'M CLR ACTIVE. I'M WAITING FOR ROGER ZZW, GO TO GND POINT 7. NO ANSWER. I HEAR, 'ZW (SQUEAK) 7 (SQUAWK) TER 21.' I ADD PWR TO CROSS 21 AS THE SMA Y IS STILL HOLDING ON 21 AND I READ BACK 'ZZW CLR TO CROSS 21, CONTACT GND AFTER XING' TO BE SURE I HEARD CORRECTLY. TWR SUPVR CALLS AND SAYS, 'ZWW STOP RIGHT NOW, HOLD SHORT 21.' I APPLY BRAKES AND SLIDE TIRES ABOUT 8' AND STOP 2' PAST HOLDING LINE. SMA Y ON 21 STILL HOLDING. I WAS TOLD TO GO TO GND .7. I DO AND CONTACT GND AND RPT HOLDING 21. THE SMA Y TAKES OFF. I'M CLRED ACROSS TO PARKING AND INFORMED TO TALK TO TWR SUPVR ON PHONE WAITING AS I DEPLANED. I TALKED TO THE SUPVR. I SAID I WOULD NOT HAVE CROSSED IF SMA Y HAD BEEN MOVING AND I THOUGHT I WAS CLRED TO CROSS. HE SAID I NEVER WAS AND HE HEARD EVERYTHING, AND I SAID MY RADIO MAY HAVE MALFUNCTIONED. HE SAID IT WAS ALMOST A VIOLATION AND A DISASTER. I TOLD HIM AGAIN IF THE SMA Y 1500' AWAY ON 21 HAD BEEN MOVING I WOULD NOT HAVE CROSSED AND WOULD HAVE RADIO CHKED. LATER ON GND FREQ #2 RADIO DIDN'T SEEM TO WORK CORRECTLY ON 121.7, VOL SCREW LOOSE. CONTRIBUTING FACTORS: EARLY AS INDEPENDENCE FBO SAID HE DIDN'T HEAR ME WHEN I LANDED, GND CHK RADIOS WORKED. EUG AREA--NEW TWR CTLR--VERY BUSY--ACCENT AND HARD TO UNDERSTAND. AIRPLANE EUG SIMILAR NUMBERS: ##ZAX. COM PROB. ALSO TRNING CTLRS AT EUG AND A LOT OF STUDENTS EUG. I'M NOT SURE EXACTLY WHAT HAPPENED TO CAUSE THIS INCIDENT. I DO KNOW IT HAS NEVER HAPPENED BEFORE AND I KNOW IT WON'T HAPPEN AGAIN BECAUSE I WILL BE SURE I HAVE POSITIVE FULL NUMBER CLRNC AND READBACK AND NOT MOVE UNTIL I AM SURE I DO HAVE CLRNC, AND I'LL ALSO BE SURE WAY IS CLR REGARDLESS OF CLRNC. HELLUVA WAY TO TREAT BRAND NEW TIRES.
