Landing
The pilot overflew his intended landing site, a gravel road, to assess its condition and the prevailing wind direction. He then executed a standard traffic pattern approach and landed to the east. The gravel road was described as 25 feet wide, down sloping to the east, and 1,000 feet in length, with a slightly winding alignment.
Incident
During the landing roll, as the aircraft decelerated through approximately 35-40 mph, the pilot detected the aircraft drifting to the right and began corrective action. He then observed that the right tire had deflated and was rolling on the rim. The right wheel subsequently entered a shallow ditch at the road's edge, causing the aircraft to depart the landing surface. The aircraft continued over rough, down-sloping terrain before nosing over and coming to rest inverted.
Post-Accident Examination
The pilot, who also held a mechanic's license, examined the right wheel after the accident and found the valve stem to be broken.
