Shortly after takeoff, as the pilot turned onto the crosswind leg of the traffic pattern and reduced engine power, the engine "went silent." The pilot initiated a descent and performed a forced landing to rough, uneven terrain, resulting in substantial damage to the airplane. Examination of the radial engine revealed the number 3 exhaust valve was fractured, due to fatigue. A review of the airplane's maintenance records revealed the engine was last overhauled approximately 7 years prior to the accident, and that the engine accumulated approximately 963 hours of operation since the overhaul. Additionally, an entry dated July 30, 2005, revealed a bird's nest was removed from the induction system.
Probable Cause: The loss of engine power due to a fatigue fractured pushrod.
