The NTSB's narrative final · quoted from the NTSB record

The flight was for familiarization purposes. The pilot, who had five hours in the airplane, at first said he didn't remember checking the fuel level, but subsequently said he added 3 gallons to the 4 gallon tank prior to departing on the first leg of a two-leg flight. While en route on the second leg of the flight at 3,500 feet agl, the pilot did one engine shutdown and an air start before the engine quit. An attempt to restart the engine failed, necessitating a forced landing to a 1,800 foot long, 100 foot wide grass airstrip. After misjudging his pattern and being 500 feet too high, the pilot used spoilers and a slipping maneuver to lose altitude. At mid field and 40 above ground level, the pilot elected to turn left 45 degrees and land in a hay field, rather than risk impacting a house located at the end of the airstrip. The airplane subsequently impacted a tree with its right wing, hit flat and sideways before coming to rest upright after having continued to rotate clockwise approximately 120 degrees.
