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 airplane took off at approximately 0645. At approximately 0700, the Civil Air Patrol (CAP) began receiving an emergency locator transmitter (ELT) signal. An aerial search failed to locate the source of the transmission. A ground search was organized at approximately 1630, and the wreckage was located that afternoon. On scene examination of the airplane showed damage characteristics consistent with a stall/spin. An autopsy revealed no evidence of physical incapacitation or impairment. Toxicological test was negative for carbon monoxide, cyanide, ethanol, and drugs. Later examination of the engine revealed the right carburetor float was hydraulically crushed and the bowl was dry. The carburetor air box was compromised during impact. There was fuel in the totalizer. Both magnetos sparked. Engine compression was confirmed on the #2 and #3 cylinders. Engine compression was not possible on cylinders #1 and #4 because impact damage to the rear accessory case compromised camshaft continuity. All four cylinders were boroscoped and revealed no anomalies. Oil pump continuity was confirmed

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

the pilot's failure to maintain adequate airspeed resulting in an inadvertent stall/spin.
