On July 8, 2004, at 1040 mountain daylight time, an Ammeter RV-6, N16JA, sustained substantial damage during landing at the Cascade Airport, Cascade, Idaho. The airplane was being operated as a visual flight rules (VFR) cross-country flight under Title 14, CFR Part 91, when the accident occurred. The private pilot and passenger aboard the two-seat airplane sustained minor injuries. Visual meteorological conditions prevailed, and no flight plan was filed. The flight originated from Susanville, California, (SVE) approximately 2 hours and 20 minutes prior to the accident. In a written statement to the National Transportation Safety Board, dated July 14, the pilot stated the airplane touched down "slightly" left of centerline and bounced. Subsequent to the bounced landing, the airplane drifted to the left and exited the runway edge. In an effort to steer the airplane back onto the runway the pilot applied right rudder and power, however, during the maneuver the airplane encountered rough/uneven terrain and nosed over.
