The pilot reported that shortly after departure the airplane’s engine lost power. The pilot selected a nearby field for a forced landing. An initial inspection of the airplane noted damage to the airplane’s wings and fuselage. Fuel was available in the airplane’s fuel tanks, and the engine had about 8 quarts of oil in it.

After the airplane was recovered, a visual inspection of the engine did not reveal any pre-impact abnormities. A test run of the engine was subsequently conducted and the engine ran at various power settings and no anomalies were noted. An examination of the fuel system revealed no anomalies.

Before and after the test run, data from an onboard engine monitor was downloaded. The data did not illustrate any abnormalities with either the cylinder head temperature or exhaust gas temperatures that were recorded; the total loss of power was evident. No abnormalities were noted during the engine test run and the engine appeared to make rated power.

A reason for the loss of engine power could not be determined with the available information.
