Narrative:

After landing on runway 21 at lee C fine airport, I turned right at the end of the runway onto the taxiway. I continued to the parallel taxiway. As I made a right turn onto the parallel taxiway, the right main gear went off the taxiway onto the grass. As I started my right turn, my copilot said 'don't turn yet.' I momentarily stopped the turn, then continued the turn to the right and the right main gear went off the taxiway. The turn on this taxiway requires a precision turn for a B727-200. Anything less than precise and you are off the taxiway.
