Narrative:

We were taxiing from the FBO to the runway in olathe; ks (ixd). The txwys from the ramp to taxiway B are not clearly marked. We were referring to the airport diagram to aid us; while we were conducting checklists. I made a right turn to get from taxiway B in order to get to the runway entrance. The taxiway extends beyond the runway entrance; and due to the fact that we were running checklists; we missed the runway entrance. On down the taxiway; there is a turnoff to some t-hangars. I tried to make a u-turn; the right main gear dropped off the pavement; and we got stuck in the mud. The line guys stated that many other aircraft have made the same mistake of missing that turn.
