Narrative:

2 aircraft cleared for an approach at FOD at the same time. Small transport X ILS 6 cleared at XX18Z, small transport Y VOR 12 cleared at XX27Z. Both aircraft were small transport aircraft. The problem was human error. This is a non radar environment and non radar arrival rules must apply. This was a failure to scan known traffic prior to issuing a clearance to aircraft. When the first aircraft landed the second was about 6 mi away from the airport inbound.
