Narrative:

I called for taxi instruction from FBO aviation. Controller told me to taxi to runway 27. I don't remember the controller telling me to hold short of runway 21 when I called for taxi instructions. While taxiing to runway 27, I ask for frequency change to mgm FSS radio to file IFR flight plan to tallahassee, fl. I told ground control I would monitor ground control. When I would key the microphone it would cut ground controller out. When I released the microphone button ground control was talking to another aircraft. I was trying to listen to ground control and a reply from FSS. I did not get a reply from mgm FSS so I switched back to ground control and ask for another frequency. When I released the microphone button FSS was calling me on FSS frequency 122.55. I was passing mgm control tower at that time. I switched back to FSS to answer them, by that time I was about 25 ft from runway 21. When I heard ground control say hold short of runway 21. At that time, my aircraft was 1/4 of the way on the runway. The next thing I knew a single engine tail dragger was passing above the nose. I did stop the aircraft on the other side of runway. From the time I heard the ground controller say hold short and my reaction time I had traveled approximately 25 ft until I came to full stop on the other side of runway. I would like to suggest that it be put in the aim that there will not be a frequency change approval at a control airport if the aircraft is to cross any runways. If the controller had told me he could not approve a frequency change I would have heard him tell me to hold short of the runway before I got on to runway 21. Upon arrival to destination, tallahassee, fl, I phoned the tower chief in mgm to discuss the incident. I also phoned gato office in birmingham, al, and reported the incident. The gato office was very cooperative about me calling before mgm tower chief called. I told them it was my fault this happened. From this incident I have learned not to ask for frequency change while taxiing.

Title: PLT OF SMT INTRUDED INTO ACTIVE RWY. CAUSED GAR OF TAIL DRAGGER TYPE ACFT. NARROWLY MISSING TAXIING RPTR ON RWY.

Narrative: I CALLED FOR TAXI INSTRUCTION FROM FBO AVIATION. CTLR TOLD ME TO TAXI TO RWY 27. I DON'T REMEMBER THE CTLR TELLING ME TO HOLD SHORT OF RWY 21 WHEN I CALLED FOR TAXI INSTRUCTIONS. WHILE TAXIING TO RWY 27, I ASK FOR FREQ CHANGE TO MGM FSS RADIO TO FILE IFR FLT PLAN TO TALLAHASSEE, FL. I TOLD GND CTL I WOULD MONITOR GND CTL. WHEN I WOULD KEY THE MICROPHONE IT WOULD CUT GND CTLR OUT. WHEN I RELEASED THE MICROPHONE BUTTON GND CTL WAS TALKING TO ANOTHER ACFT. I WAS TRYING TO LISTEN TO GND CTL AND A REPLY FROM FSS. I DID NOT GET A REPLY FROM MGM FSS SO I SWITCHED BACK TO GND CTL AND ASK FOR ANOTHER FREQ. WHEN I RELEASED THE MICROPHONE BUTTON FSS WAS CALLING ME ON FSS FREQ 122.55. I WAS PASSING MGM CTL TWR AT THAT TIME. I SWITCHED BACK TO FSS TO ANSWER THEM, BY THAT TIME I WAS ABOUT 25 FT FROM RWY 21. WHEN I HEARD GND CTL SAY HOLD SHORT OF RWY 21. AT THAT TIME, MY ACFT WAS 1/4 OF THE WAY ON THE RWY. THE NEXT THING I KNEW A SINGLE ENG TAIL DRAGGER WAS PASSING ABOVE THE NOSE. I DID STOP THE ACFT ON THE OTHER SIDE OF RWY. FROM THE TIME I HEARD THE GND CTLR SAY HOLD SHORT AND MY REACTION TIME I HAD TRAVELED APPROX 25 FT UNTIL I CAME TO FULL STOP ON THE OTHER SIDE OF RWY. I WOULD LIKE TO SUGGEST THAT IT BE PUT IN THE AIM THAT THERE WILL NOT BE A FREQ CHANGE APPROVAL AT A CTL ARPT IF THE ACFT IS TO CROSS ANY RWYS. IF THE CTLR HAD TOLD ME HE COULD NOT APPROVE A FREQ CHANGE I WOULD HAVE HEARD HIM TELL ME TO HOLD SHORT OF THE RWY BEFORE I GOT ON TO RWY 21. UPON ARRIVAL TO DEST, TALLAHASSEE, FL, I PHONED THE TWR CHIEF IN MGM TO DISCUSS THE INCIDENT. I ALSO PHONED GATO OFFICE IN BIRMINGHAM, AL, AND RPTED THE INCIDENT. THE GATO OFFICE WAS VERY COOPERATIVE ABOUT ME CALLING BEFORE MGM TWR CHIEF CALLED. I TOLD THEM IT WAS MY FAULT THIS HAPPENED. FROM THIS INCIDENT I HAVE LEARNED NOT TO ASK FOR FREQ CHANGE WHILE TAXIING.
