Human Factors
I was accomplishing a practice ILS approach to Runway 22 at McMinnville Airport (MMV); Oregon in a Cessna 152 aircraft. The weather included an overcast layer of clouds from about 2;200 to 3;000 FT MSL. It was clear above and clear below the layer. I was operating on an IFR flight plan and talking with Portland Approach. During the straight-in approach and about 11 NM prior the runway; I was advised by Approach to change advisory frequency (CTAF) and to contact Approach again during the planned missed approach. Following the frequency change; I monitored the CTAF for a few miles with the intent of making my initial traffic advisory call just prior to glideslope intercept; which is 5.2 miles prior to the runway. About 7 to 8 miles prior to the runway; I descended below bottom of the overcast layer; into visual weather conditions. About 6 miles prior to the runway; another aircraft made an advisory call indicating they too were on the same ILS approach to Runway 22 at McMinnville. Their call indicated they were about 8 miles prior to runway (about 2 miles behind me). I assume the other pilot was making a practice ILS approach in VFR conditions; hopefully operating below the overcast layer.  Immediately following their call; I made a traffic advisory call to include my position on the ILS approach. The pilot of the other aircraft asked for my airspeed; to which I replied 99 knots. The pilot declared his intent to pass directly below my aircraft. I continued the approach; visually searching for the other aircraft. In hindsight; I should have executed a climb out along the localizer course. About 4 miles prior to the runway I observed a much faster single-engine low-wing aircraft directly below my nose. The other pilot completed their approach; accomplished a missed approach and departed the area. I never heard any other radio calls from the aircraft.  This is the first time I've ever been intentionally passed on an ILS approach.
Cessna 152 pilot reported he had an NMAC with another aircraft on approach to MMV when he was passed by the other aircraft during the approach.
