DEN03LA073

The pilot reported on takeoff having a normal acceleration and run. The pilot said, "The airplane uncharacteristically failed to produce additional RPMs once airborne." The pilot determined that he would have to bring the airplane back for landing. The pilot said he initiated a left turn to crosswind and lowered an additional 10 degrees of flaps. The pilot said that it was at this point that he was near minimum controllable airspeed. The airplane started a slow descent. The pilot said he turned the airplane from crosswind to aim it back toward the center of the airport. The pilot said, "As I rolled level I noted the airspeed indicator at 40 miles per hour, which I maintained all the way down to touchdown in a stable descent." The pilot said that at approximately 20 feet above the ground, he pulled back slightly on the yoke in an attempt to flare the airplane. The right wing dropped, and the airplane impacted the ground, bounced, and went inverted. An examination of the airplane's engine showed the number 2 cylinder exhaust valve stuck in the open position. No other anomalies with the airplane were found. The density altitude for the area at the time of the accident was 8,133 feet. The pilot reported the winds on takeoff as 250 degrees at 8 knots. An examination of the engine logbook showed that 9 months earlier, the number 2 cylinder exhaust valve was found stuck open after an aborted takeoff. The valve was unstuck and an engine run and test flight was conducted. From the time of the aborted takeoff incident to the time of the accident, the airplane logged approximately 2 hours total time.

On April 26, 2003, at 1210 mountain daylight time, a Cessna 175A, N6884E, piloted by a commercial pilot, was substantially damaged when it impacted in a field 1/4 mile south of Meadow Lake Airport, Colorado Springs, Colorado. Visual meteorological conditions prevailed at the time of the accident. The personal flight was being conducted on a visual flight rules flight plan under the provisions of Title 14 CFR Part 91. The pilot on board the airplane reported no injuries. The cross-country flight to Crawford, Colorado, was originating at the time of the accident.

The pilot reported setting his flaps to 10 degrees for takeoff prior to taking off on runway 15 (6,000 feet by 60 feet, dry asphalt). The pilot reported on takeoff having a normal acceleration and run. The pilot said, "The airplane uncharacteristically failed to produce additional RPMs once airborne." The pilot determined that he would have to bring the airplane back for landing. The pilot said he initiated a left turn to crosswind and lowered an additional 10 degrees of flaps.

The pilot said that at approximately 20 feet above the ground, he pulled back slightly on the yoke in an attempt to flare the airplane. The right wing dropped, and the airplane impacted the ground, bounced, and went inverted.

The airplane was examined at the accident scene. The airplane rested inverted in a field. The nose wheel was broken aft. The lower engine cowling was bent downward and crushed aft. The bottom engine mounts were broken downward. The engine was bent downward approximately 30 degrees. The propeller showed torsional bending and chordwise scratches. The windscreen was broken out. The right wing tip was bent upward approximately 10 degrees. The top wing skin inboard of the wing tip was crushed inward. The remaining top skin of the right wing was buckled. The left wing tip was bent upward and crushed aft along the leading edge. The top wing skin was buckled aft and wrinkled. The inboard aft portion of the left wing near the root was crushed downward. The left flap was bent downward at mid-span. The aft fuselage was bent downward midway between the baggage compartment and the empennage. The vertical stabilizer and rudder were crushed downward. The horizontal stabilizers and elevators were intact. Flight control continuity was confirmed. An examination of the engine showed the number 2 cylinder exhaust valve stuck in the open position. No other anomalies with the airplane were found.

The weather at Colorado Springs Municipal Airport, located 225 degrees at 14 miles, approximately 9 minutes after the accident, was clear skies, 10 miles visibility, temperature 64 degrees Fahrenheit, dew point 34 degrees F, winds 140 degrees at 5 knots, and an altimeter 29.77. The density altitude was calculated to be 8,133 feet. The pilot reported the winds at the time of the accident as 250 degrees at 8 knots.

An examination of the engine logbook showed the airplane underwent an annual inspection on June 29, 2002. The total airframe time at the last annual inspection was 3,496:01 hours. The last entry in the engine logbook was dated July 12, 2002, and read, "Abort takeoff, removed cowl, pulled upper plugs. Comp[ression] test accomplished. Found number 2 cylinder exhaust valve stuck in the open position. Removed valve cover, unstuck valve. Test run engine. Test flight aircraft. Operation normal within limits. End." The total airframe time at the last entry was 3,497:01 hours. The total airframe time at the accident was 3,499:03 hours.
