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

The airplane impacted the terrain following a loss of control of takeoff. The accident occurred on the pilot's 1,000 foot long private grass airstrip. The pilot reported that the winds were calm when he landed approximately one hour prior to the accident. He stated he checked the windsock prior to takeoff and it was indicating that the winds had increased and there was a left crosswind. The pilot reported the wind at the south end of the runway was stronger than what the wind sock was indicating, and the airplane veered to the right on takeoff because he "...did not correct adequately for the wind." The pilot reported that his altitude was lower than normal and he pulled up to avoid a fence at the end of the property. He stated the airplane stalled and the nose dropped. The airplane impacted the terrain and came to rest about 60 feet from the right side of the airstrip.
