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

According to the pilot, the engine start, taxi, and engine run-up prior to takeoff were normal, without issues, or anomalies. The airplane departed from runway 28. After raising the landing gear, the pilot noted that the engine rpms were dropping through 2,100 rpm. The pilot communicated with the air traffic control tower, performed a 90 degree turn to the left to avoid terrain and obstacles, and performed a forced landing to rough, uneven terrain. During the landing the nosegear assembly and the right main landing gear separated. The airplane rotated 90 degrees to the right, slid, and came to rest on the right wing, resulting in substantial damage. An examination of the engine revealed no anomalies. The fuel selector valve was removed for further examination and testing. The valve exhibited fuel staining on the main tank inlet and fuel line fitting. The gascolator exhibited fuel staining on the top left side of the casting and on the bottom at the fuel sump location. During the vacuum test the valve bled down more than 10 inches in one minute. The gascolater was compromised and leaked severely. Leaks in the fuel selector valve and gascolator can allow air into the fuel system and result in the loss of engine power.

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

A leak in the fuel selector valve and gascolator that resulted in fuel starvation during takeoff. Contributing to the accident was a lack of suitable terrain for a forced landing.
