Narrative:

We got a taxi clearance to taxi to runway 17, no other instructions. We were parked on the east ramp so I thought we had to taxi across 2 runways to get to runway 17. In the clearance there were no instructions holding short of runways. When time came to cross runway #2 I saw a plane on final I estimated that the airplane was far away enough for us to proceed. The clearance clearly allowed us to cross any runway to get to runway 17 -- far 91.129(I). After passing the second runway we asked the tower if they were calling us. They had called a different aircraft number. They told us to do a 180 degree and hold. They then gave us instructions to taxi to runway 17 and that we had to call the tower after the flight. I was later told that the controller told the aircraft on final to do a go around. I later got to know that there was a better way to get to runway 17. How the problem arose: miscom. Contributing factors: pilot being unfamiliar with the east ramp and controller not giving exact taxi instructions. How it was discovered: controller informed pilot after passing second runway. Corrective action: plane on final did a go around and I was told to call the tower. Human performance -- instructor would under other circumstances asked for clarification of the clearance. That day I had been in constant discussion with the student through the whole flight.

Title: RPTR, FLT INSTRUCTOR, ALLOWED PVT PLT STUDENT TO CROSS RWY WITHOUT CLRNC.

Narrative: WE GOT A TAXI CLRNC TO TAXI TO RWY 17, NO OTHER INSTRUCTIONS. WE WERE PARKED ON THE E RAMP SO I THOUGHT WE HAD TO TAXI ACROSS 2 RWYS TO GET TO RWY 17. IN THE CLRNC THERE WERE NO INSTRUCTIONS HOLDING SHORT OF RWYS. WHEN TIME CAME TO CROSS RWY #2 I SAW A PLANE ON FINAL I ESTIMATED THAT THE AIRPLANE WAS FAR AWAY ENOUGH FOR US TO PROCEED. THE CLRNC CLRLY ALLOWED US TO CROSS ANY RWY TO GET TO RWY 17 -- FAR 91.129(I). AFTER PASSING THE SECOND RWY WE ASKED THE TWR IF THEY WERE CALLING US. THEY HAD CALLED A DIFFERENT ACFT NUMBER. THEY TOLD US TO DO A 180 DEG AND HOLD. THEY THEN GAVE US INSTRUCTIONS TO TAXI TO RWY 17 AND THAT WE HAD TO CALL THE TWR AFTER THE FLT. I WAS LATER TOLD THAT THE CTLR TOLD THE ACFT ON FINAL TO DO A GAR. I LATER GOT TO KNOW THAT THERE WAS A BETTER WAY TO GET TO RWY 17. HOW THE PROB AROSE: MISCOM. CONTRIBUTING FACTORS: PLT BEING UNFAMILIAR WITH THE E RAMP AND CTLR NOT GIVING EXACT TAXI INSTRUCTIONS. HOW IT WAS DISCOVERED: CTLR INFORMED PLT AFTER PASSING SECOND RWY. CORRECTIVE ACTION: PLANE ON FINAL DID A GAR AND I WAS TOLD TO CALL THE TWR. HUMAN PERFORMANCE -- INSTRUCTOR WOULD UNDER OTHER CIRCUMSTANCES ASKED FOR CLARIFICATION OF THE CLRNC. THAT DAY I HAD BEEN IN CONSTANT DISCUSSION WITH THE STUDENT THROUGH THE WHOLE FLT.
