Narrative:
Departed geg about XA30 and was in level cruise at 8500 ft on course to cvo, or, when catastrophic engine failure occurred. I was still on geg departure frequency, declared an emergency. Was being vectored back to geg but unable to glide that far. I landed in a grassy field with no damage to aircraft and no injury to pilot (only occupant). Initial engine inspection showed #4 cylinder rod thrown through engine head. Total time on factory remanufactured lycoming was 172 hours.
