NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The private certificated pilot was planning to test a remote tundra-covered area for its suitability as a landing strip. The area selected was adjacent to a river. The pilot said he configured the airplane with 20 degrees of flaps, and touched the main landing gear tires on the tundra to test the surface. The tires dug into the soft tundra and the airplane nosed over. The airplane received damage to the propeller, fuselage, vertical stabilizer, and the rudder.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's selection of unsuitable terrain for landing, which resulted in the airplane nosing over during the landing flare/touchdown. A factor contributing to the accident was soft tundra terrain.
