Narrative:
A Grumman G-164B airplane, N6696K, was substantially damaged when it was involved in an accident near Colusa, California. The pilot was not injured.
The pilot reported that he was approaching a field to begin the application when the engine made a popping noise and started to vibrate. The airplane slowed and the pilot initiated a turn toward a nearby runway. Since the airplane was still losing speed, the pilot added power, but the vibration increased until the engine lost total power. The airplane impacted terrain and came to rest upside down, resulting in substantial damage to the wings and empennage.

Probable Cause and Findings
Total loss of engine power for reasons that could not be determined based on the available information.
