Narrative:
The experimental amateur-built airplane sustained substantial damage when the airplane nosed over on impact with high vegetation and terrain during a forced landing following an in-flight loss of engine power. The pilot stated, "At first sign of [decreased] power, turned in direction of nearest airport. Altitude was about [2,800 feet]. Ran fuel selector through all positions; no improvement noted. Determined nearest airport unreachable. Found empty field and directed airplane toward it. Landed short in field [with] tall corn. Aircraft slowed, nose dug in, flipped forward onto its back." An examination of the wreckage did not reveal any pre-impact anomalies.

Probable Cause: The in-flight loss of engine power during cruise for undetermined reasons and the unsuitable terrain the pilot encountered during the forced landing. A factor was the tall corn he encountered.
