Narrative:

After an uneventful revenue flight [to] rkd; we were cleared for a visual approach by portland approach. The primary frequency was switched to knox co regional unicom and all radio calls were made at the appropriate times with regards to our location from this non-tower controlled airport. The wind favored an approach to runway 31; and we were approximately 5 minutes in [the] trail of a jet that had just landed; it was taxiing clear of runway 31 as we made our turn to enter a left downwind. Several light civil aircraft were also in the traffic pattern conducting approaches to runway 21. Just after the second in command (sic) made an advisory call indicating we were on a 1-mile final; a [aircraft] reported taxiing from the ramp for runway 21. A normal landing was conducted; and as we were about to cross runway 21 on the landing rollout; I caught an airplane out of the corner of my eye. The aircraft passed directly overhead by no greater than 200 feet; and was close enough that the sound of its engine was audibly very loud. Immediately afterward; a radio transmission was made by an aircraft stating; 'boy; that was close;' followed by a transmission from the aircraft that had flown over us; very casually stating; 'that wasn't as close as it looked.' then; 'my bad.' I was somewhat rattled and did not think to ask for the aircraft's registration number; nor do I recall the aircraft calling that it was clear of the traffic pattern; it did not remain in the pattern; however. All I remember was that the aircraft was green and much too close. Neither I nor the sic heard a radio transmission indicating that the aircraft was departing runway 21 after its initial taxi call. This would have been our opportunity to make an additional radio transmission indicating that we were about to; or had already landed on the intersecting runway; and for that aircraft to delay their takeoff until we were clear of the runway. After taxiing to the ramp; shutting the aircraft down and disembarking our passenger; we discussed the event as a crew. We came to the conclusion that there wasn't anything we would have done differently; and were very grateful for the outcome.
