The airplane was destroyed when it impacted a cornfield during cruise flight. Night instrument meteorological conditions prevailed at the time of the accident. The flight was operating under visual flight rules (VFR), and no flight plan was filed. There was no record of the pilot contacting air traffic control facilities or Flight Service Stations while en route. There were no witnesses to the accident. The pilot was a private pilot but he was not instrument qualified. The pilot's logbook indicated that he flew 0.5 hours of night time 30 days prior to the accident, and that he recorded 3 landings to a full stop. The pilot's previous night flight, which was 0.6 hours in length, was logged nine months prior to the accident. The observed weather about 26 nautical miles west of the accident site, was: Winds 260 degrees at 7 knots, visibility 2 statute miles, light snow, ceiling 700 feet overcast, temperature 1 degree C, dew point 0 degree C, altimeter 29.89 inches of mercury. The postaccident inspection of the airplane revealed no preexisting anomalies that could be associated with a pre-impact condition.

WRECKAGE AND IMPACT INFORMATION The accident site was located in a harvested cornfield in an area of rolling hills. The coordinates were 41 degrees 42.342 minutes north latitude, 092 degrees 27.005 minutes west longitude. The wreckage path was approximately 700 feet from the initial point of impact to the main wreckage on a 035 degree magnetic heading. Both of the wings, the wingtip fuel tanks, and the outboard section of the right horizontal stabilator separated from the fuselage during the impact sequence. The vertical stabilator was displaced to the left and partially separated from the empennage. There was no ground fire. The left and right wingtip fuel tanks were located about 150 feet from the initial point of impact. The left wing was located about 285 feet in the wreckage path. The wing was bent upward near mid span. The aileron and flap remained attached. The aileron bellcrank was separated from its mounting and pulled inboard. The aileron control and balance cable was verified from the left bellcrank to the control wheel chain and from the left bellcrank to the right side bellcrank. The landing gear was separated and was found along the wreckage path. The right wing was located about 375 feet in the wreckage path. The wing was pushed inboard and buckled near mid span and was in a "U" shape. The aileron remained attached but the aileron bellcrank was separated from its mounting and pulled inboard. The balance cable continuity was verified to the left bellcrank. The control cable was separated near the wing root. The separation was frayed and was consistent with overload impact damage. The landing gear was separated and was found along the wreckage path. The empennage remained attached to the fuselage. The horizontal stabilator remained in place, although the outboard section of the right horizontal stabilator was separated along the rivet line. The hinge points were secure and the stop bolts were in place. The control cables were secure and continuity was verified to the control wheel 'T' bar in the cockpit. Elevator trim was found at a setting of about 1 1/2 - 2 degrees nose down trim. The cabin of the fuselage was partially separated at the windshield line. All control cables remained attached to the cockpit controls. The air-driven attitude gyro, the air-driven directional gyro, and the electric-driven turn and bank gyro were disassembled. The gyros exhibited no rotational impact marks. The inspection of the engine revealed that the crankshaft rotated. The engine drive train exhibited continuity to all the aft gears and rocker arms. Thumb compression and suction were confirmed to all cylinders. Both magnetos were rotated and they exhibited spark from all leads at the caps. The carburetor was separated from the engine and found along the wreckage path. The propeller and spinner remained attached to the engine. One blade was bent more that 90 degrees aft near mid span. There was a gouge in the leading edge of the blade and chordwise scratches on the front of the blade. The other blade was twisted and bent opposite the direction of rotation and the tip was curled near the end of the blade. The spinner was crushed in a spiral shape. MEDICAL AND PATHOLOGICAL INFORMATION The autopsy was performed on the pilot at the Broadlawn's Hospital, Des Moines, Iowa. A Forensic Toxicology Fatal Accident Report was prepared by the FAA Civil Aeromedical Institute. The report was negative for all substances tested. ADDITIONAL INFORMATION The Federal Aviation Administration, the New Piper Aircraft Company, and Textron Lycoming were parties to the investigation. The wreckage was released to the Midwest Aviation Adjustment Bureau, Inc.
The pilot's inadequate planning/decision resulting in VFR flight into IMC, and his failure to maintain terrain clearance resulting in in-flight collision with terrain. Contributing factors to the accident were the pilot's lack of an instrument rating, his lack of recent night flying experience, the dark night, and the low ceilings.
