"THIS CASE WAS MODIFIED AUGUST 19, 2008." The pilot reported to air traffic control that the experimental amateur built airplane's engine was malfunctioning. A forced landing was made in a corn field, across the corn rows. The airplane nosed over and caught fire. Examination of the engine revealed that both left cylinders had no compression, and the cylinder head bolts were found with zero torque. The lower forward hold down bolt was found backed out 1/8 inch. After removing the cylinder head and barrels for both left cylinders, evidence of severe combustion gas blow by was found on both barrels and both heads. Metal was melted out of the heads at the bottom forward and bottom aft hold down bolt areas. The loose cylinder head barrels would have resulted in a significant loss of engine power. Toxicology testing revealed that the pilot had recently used two different impairing medications, but it is unclear whether the medication use was relevant to the accident sequence.
