Narrative:

I am a partner in a rockwell commander hangared at montgomery field in san diego. My partner taxied the aircraft to the maintenance facility. Since he was not available and the maintenance was complete, I decided to taxi the aircraft back to our hangar. I began taxiing the plane back from the maintenance facility. I started the engine, taxied to the boundary of taxiway I (at taxiway G). I called montgomery ground control for a taxi clearance. Ground cleared me to taxi to parking. I turned right onto taxiway G and missed the turn onto taxiway H and proceeded right onto runway 10R, which parallels taxiway H. Looking down the runway, I saw a cessna on short final transitioning to a go around. Ground immediately contacted me and asked me where I was going. I made a mistake and told him so. Ground told me to turn around and exit the runway, which I did. Then he cleared me to taxi to parking on taxiway H. Ground asked if I was a licensed pilot. I said I was. After I reached taxiway J, ground instructed me to contact the tower. I have had a pilot's certificate since jan/54. My medical expired in 1995 and since that date I have never flown without another licensed pilot acting as PIC.
