C550 HAS A RUNWAY INCURSION AT KCPR.

Narrative

THIS IS A FULL BLOWN IDIOTIC RWY INCURSION AT CPR; WY. WE WERE TAXIING TO RWY 21 VIA TXWY A AND ALPHA 7. ALPHA RUNS PARALLEL TO THE RWY AND IS PHYSICALLY PART OF THE RAMP IN FRONT OF THE FBO. INSTEAD OF TURNING R ON ALPHA; I CROSSED ALPHA AND MADE THE FIRST R TURN WHICH WAS THE ACTIVE RWY 21. I IMMEDIATELY REALIZED MY MISTAKE AND AT THE SAME TIME GND CTL CALLED THE ERROR. THERE WAS A SINGLE ENG AIRPLANE ON THE RWY WHICH HAD JUST LANDED AND WAS READY TO TURN OFF ABOUT 2000-3000 FT DOWNWIND OF US. THEREFORE; THERE WAS NO REAL PHYSICAL CONFLICT. THE SIMPLE EXPLANATION IS THE AGE OLD PROB OF DISTR. OUR COMPANY PREFERS TO OPERATE THE CITATION WITH 2 PLTS IN THE COCKPIT; BUT OPERATING A RELATIVELY LOW NUMBER OF HRS PER YR; WE HAD ONLY HIRED 1 FULL TIME PLT (ME). I AM AUTH TO FLY SINGLE PLT. FOR OUR SECOND (CONTRACT) PLT WE CHOSE THE MOST QUALIFIED SIC AVAILABLE. WHEN A PLT DOES NOT MEET THE INSURANCE REQUIREMENTS FOR COCKPIT CREW MEMBERS; THEN I AM TECHNICALLY OPERATING SINGLE PLT; AS I WAS ON THIS DAY. I AM LIMITED ON HOW I MAY USE THE OTHER PLT IN THIS SCENARIO. I MAINLY HAVE HIM HELP WITH THE CHKLISTS AND RADIOS. AT THE TIME OF THIS INCIDENT; I HAD DIVERTED MY ATTN FROM TAXIING TO EXPLAINING A CHKLIST ITEM HE WAS MISSING. THAT WAS MY MISTAKE. IN MY 'SEMI CONSCIOUS' MIND I WAS EXPECTING TO CROSS A MEDIAN IN MY SHORT TRIP TO TXWY A. I DID JUST THAT AND THEN TURNED L ONTO THE RWY 'THINKING' IT WAS THE TXWY. I QUICKLY REALIZED MY MISTAKE ABOUT THE SAME TIME AS GND CTL CALLED THE ERROR. I DID A QUICK 180 DEG TURN; THEN EXITED THE RWY; WHICH WAS THE FIRST OPTION OFFERED BY GND CTL.
