Analysis narrative
The helicopter pilot reported that, during his third agricultural application pass over a hilly field, he quickly glanced at an instrument inside the cockpit, and the helicopter impacted terrain.

A Federal Aviation Administration inspector reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
