Aircraft Accident/Incident Report

Summer Lake, Oregon 97640
Thursday, April 26, 2001 12:00 PDT

NTSB Narrative Summary Released at Completion of Accident

The pilot elected to make an off-field landing in an area that had previously been covered by a lake when water levels were higher. The pilot used soft-field techniques, and the initial touchdown was uneventful. But, as the aircraft slowed, it sank into the soft terrain and nosed over. The pilot had taken no action to determine the firmness of the terrain prior to landing.

NTSB Probable Cause Narrative

the pilot's decision to land on a dry lake bed without first taking action to determine the firmness of the surface. Factors include soft terrain at the location the pilot chose to land.
