Accident Details
A pilot and a passenger flew to a privately-owned airport. During the approach, the pilot circled the airport and performed a low pass to assess the runway condition. The turf runway had not been mowed recently and was covered with tall grass. No standing water was visible from the air. After touchdown, the airplane rolled down the runway and encountered a soft surface with standing water that had been hidden by the grass.
Sequence of Events
The main landing gear sank into the soft ground, causing the airplane to nose over. The aircraft came to rest on its wings and vertical stabilizer. Both occupants were able to exit the airplane and reported no injuries.
Damage Assessment
The airplane sustained substantial damage to the left wing spar and the vertical stabilizer. The pilot reported that there were no mechanical deficiencies with the airplane prior to the accident.
