Narrative:

Just after changing frequencies to miv for instrument approach in VFR/VMC to validate instrumentation; small low-wing white and red private aircraft was visually noted approaching almost level at the 11'oclock; at a high rate of closure. Miv facility and other aircraft did not announce traffic conflict. Aircraft passed beneath (~100 feet) and subsequently noted they were number two for runway 10 ILS. The high volume of fixed wing traffic (especially in decent weather) at miv should warrant controlled class D airspace with a manned control tower during daylight hours when traffic is heaviest. Quite often the traffic fails to make radio calls; or makes wildly inaccurate position reports; adding to the possibility for a mid-air incident somewhere in the vicinity of the airport.

Title: After experiencing an NMAC with a light aircraft arriving the same uncontrolled airport; MIV; the pilot of a BV-234 helicopter expressed the opinion the airport is busy enough to warrant at least a daytime ATC presence.
