Narrative:
Propeller failure. Engine shut down due to extreme vibration. Landed in a farmer's field. Nose strut bent due to softness of dirt field. No other damage, no injuries. Location and altitude -- 1 mi north of south county airport, san martin, ca, 1300 ft asl. Flight plan and altimeter setting - - VFR in traffic pattern. South county elevation used to set altimeter (281 ft). WX -- cavu. No injuries. FAA notified by phone. Callback conversation with reporter revealed the following information: reporter states the FAA came to check the aircraft and propeller. They could find nothing that indicated why the propeller failed. The manufacturer inspected the propeller and came to the conclusion that it was simply a structural failure of the propeller. The aircraft has been repaired and is flying again. This is a home built experimental aircraft, a challenger 2.

Title: PLT OF CHALLENGER 2 HOME BUILT ACFT HAS A PROP FAILURE RESULTING IN AN ENG SHUTDOWN DUE TO EXTREME VIBRATION AND AN OFF ARPT LNDG.
Narrative: PROP FAILURE. ENG SHUT DOWN DUE TO EXTREME VIBRATION. LANDED IN A FARMER'S FIELD. NOSE STRUT BENT DUE TO SOFTNESS OF DIRT FIELD. NO OTHER DAMAGE, NO INJURIES. LOCATION AND ALT -- 1 MI N OF SOUTH COUNTY ARPT, SAN MARTIN, CA, 1300 FT ASL. FLT PLAN AND ALTIMETER SETTING - - VFR IN TFC PATTERN. SOUTH COUNTY ELEVATION USED TO SET ALTIMETER (281 FT). WX -- CAVU. NO INJURIES. FAA NOTIFIED BY PHONE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATES THE FAA CAME TO CHK THE ACFT AND PROP. THEY COULD FIND NOTHING THAT INDICATED WHY THE PROP FAILED. THE MANUFACTURER INSPECTED THE PROP AND CAME TO THE CONCLUSION THAT IT WAS SIMPLY A STRUCTURAL FAILURE OF THE PROP. THE ACFT HAS BEEN REPAIRED AND IS FLYING AGAIN. THIS IS A HOME BUILT EXPERIMENTAL ACFT, A CHALLENGER 2.
