Human Factors
I was flying the 18 DME arc segment of the VOR/DME-C approach to KFCH; between BLEAR and IKOGY. While flying at 2000 AGL; at approximately the 195 radial; TRACON called VFR traffic not in communication with approach; opposite direction at 2500 AGL. I reported visual contact and the other aircraft (another Beechcraft) passed 500 feet overhead. A short time later; TRACON reported the traffic had reversed direction to follow me. I checked and verified traffic at my 5 o'clock position. TRACON called for a turn to the north; by which time the traffic had passed toward my 7 o'clock position. I regained visual contact with the traffic and saw it moving toward my 9 o'clock position; approximately 150 feet laterally to my left and 100 feet above my altitude. I replied that I would be deviating from the route and assigned altitude as required to maintain separation. The other aircraft basically flew in formation at my 9 o'clock position maintaining 150 feet lateral and 100 feet vertical separation for 15-30 seconds; followed by a pitch up and right turn to cross over my aircraft.By this time; I was flying through the final approach course and TRACON asked for my intentions; offering a clearance or vectors as desired. I requested and was cleared for the approach with the intent of a missed approach to the hold. The conflict situation was a significant distraction; and the controller and I did not coordinate an altitude for the missed approach hold prior to executing the missed - however; we coordinated on the go for 3000 AGL.Two things stand out. First; attempting formation flight without prior coordination or communication was an unprofessional act on the part of the other pilot. Second; the best course of action on my part would have been vectors to a new approach.
The pilot of a single engine Beechcraft reported a near-mid-air-collision while on an instrument approach near FCH; with another single engine Beechcraft that maneuvered nearby without coordination.
