I departed and climbed up to 6;500 feet MSL. While enroute after about 20 minutes cruising I experienced a sudden vibration followed by an immediate power loss to about 1500 RPM. I followed all engine loss procedures to no avail. Unable to maintain altitude; I located a field and executed a successful forced landing which resulted in no damage to the aircraft; me; or the owners' property; other than disturbing some cows. The aircraft had recently been through an annual inspection. However; I was unaware that the pitot static system and the transponder check were not covered by the inspection. Earlier that day I flew out of an airport which is located under Class B airspace. I spent about 10 minutes in the Class B shelf area flying out to the west. I made some research after the incident and according to my best knowledge by now; I should have had the Mode C Transponder inspected even for a day VFR flight within 30 NM radius at any altitude below the top and around the main airport of the Class B airspace.
A Cessna 150 engine failed at 6;500 FT in cruise. The pilot landed the ferry flight successfully off airport and later discovered that having departed Class B airspace the aircraft's transponder and pitot-static systems had not been checked.
