Narrative:

An small aircraft X with a crew of 2 licensed pilots on a routine power line patrol. The craft was approaching cid from the south. The small aircraft X flew to the inner ring of the arsa under the outer and executed a left 270 degree turn to avoid the arsa. This put the craft on an 090 degree heading. When able the patrol plane small aircraft X called approach and told them of position, that is 'power line patrol south of swisher, 1100' MSL and intentions were to return to marion (C17) airport.' approach gave a squawk code but was told that the craft might be negative transponder noted from earlier problems. Approach gave out a heading of 030 degrees for radar identify, which turned the patrol into the arsa where radar identify was made. The rest was normal: 'radar contact, resume own navigation and report marion in sight,' and upon landing at marion the PIC returned a phone call to approach and talked to manager at the event.
