Narrative:

We landed on runway 25R in phx. We were instructed to make a left turn at the end of the runway and taxi to the ramp on golf. I turned the aircraft off golf, following what I thought was the taxiway to our ramp. Upon completing the turn, I did not see our parking spot. The aircraft was stopped, ATC was queried and the spot was located. I now believe I turned off golf prematurely. Our parking spot was at about our 11 O'clock position and less than one fourth mile to get to it. I made a 90 degree left turn (following what I thought was a taxi line) and joined the taxi line back to our ramp. This involved a 90 degree turn to the right to join this line which was about 200 ft up from where I had originally turned in. During this taxi a truck with a flashing light drove toward us from the military facility. After we blocked in we were informed by company that the military had called about the aircraft being on their ramp. Company also informed us that there is a red line designating the military ramp. I never saw a red line and I still don't know that I was definitely in their area. The area was dark and not marked well. It is a new area for my company and neither my co-pilot nor myself had parked there before. This could have been avoided by my locating the spot prior to my turn. In addition, better lighting, markings and a more detailed airport diagram page may have provided assistance. Callback conversation with reporter revealed the following information: reporter stated they were not forewarned by ATC of a potential conflict, and that their company is doing a follow-up on the incursion to advise other crews of the potential conflict.

Title: A B767 FREIGHTER CREW TURNED PREMATURELY, ENTERING A MIL RAMP, INSTEAD OF THE INTENDED CARGO RAMP.

Narrative: WE LANDED ON RWY 25R IN PHX. WE WERE INSTRUCTED TO MAKE A LEFT TURN AT THE END OF THE RWY AND TAXI TO THE RAMP ON GOLF. I TURNED THE ACFT OFF GOLF, FOLLOWING WHAT I THOUGHT WAS THE TXWY TO OUR RAMP. UPON COMPLETING THE TURN, I DID NOT SEE OUR PARKING SPOT. THE ACFT WAS STOPPED, ATC WAS QUERIED AND THE SPOT WAS LOCATED. I NOW BELIEVE I TURNED OFF GOLF PREMATURELY. OUR PARKING SPOT WAS AT ABOUT OUR 11 O'CLOCK POSITION AND LESS THAN ONE FOURTH MILE TO GET TO IT. I MADE A 90 DEGREE LEFT TURN (FOLLOWING WHAT I THOUGHT WAS A TAXI LINE) AND JOINED THE TAXI LINE BACK TO OUR RAMP. THIS INVOLVED A 90 DEGREE TURN TO THE RIGHT TO JOIN THIS LINE WHICH WAS ABOUT 200 FT UP FROM WHERE I HAD ORIGINALLY TURNED IN. DURING THIS TAXI A TRUCK WITH A FLASHING LIGHT DROVE TOWARD US FROM THE MIL FACILITY. AFTER WE BLOCKED IN WE WERE INFORMED BY COMPANY THAT THE MIL HAD CALLED ABOUT THE ACFT BEING ON THEIR RAMP. COMPANY ALSO INFORMED US THAT THERE IS A RED LINE DESIGNATING THE MIL RAMP. I NEVER SAW A RED LINE AND I STILL DON'T KNOW THAT I WAS DEFINITELY IN THEIR AREA. THE AREA WAS DARK AND NOT MARKED WELL. IT IS A NEW AREA FOR MY COMPANY AND NEITHER MY CO-PILOT NOR MYSELF HAD PARKED THERE BEFORE. THIS COULD HAVE BEEN AVOIDED BY MY LOCATING THE SPOT PRIOR TO MY TURN. IN ADDITION, BETTER LIGHTING, MARKINGS AND A MORE DETAILED AIRPORT DIAGRAM PAGE MAY HAVE PROVIDED ASSISTANCE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THEY WERE NOT FOREWARNED BY ATC OF A POTENTIAL CONFLICT, AND THAT THEIR COMPANY IS DOING A FOLLOW-UP ON THE INCURSION TO ADVISE OTHER CREWS OF THE POTENTIAL CONFLICT.
