N159JW

HISTORY OF FLIGHTOn September 8, 2011, about 1122 eastern daylight time, a Cirrus SR22, N159JW, impacted a cornfield near West Liberty, Ohio, and was destroyed by impact forces and postimpact fire. The private pilot, the sole occupant, received fatal injuries. The airplane was registered to Windsor Ltd LLC and was operated by the pilot under the provisions of the 14 Code of Federal Regulations Part 91 as a business flight. Instrument meteorological conditions prevailed at the time of the accident, and no flight plan was filed. The flight originated from the Bellefontaine Regional Airport (EDJ), Bellefontaine, Ohio, about 1118.

Witnesses reported that the pilot intended to land at Urbana, Ohio, located about 15 nautical miles (nm) south of EDJ and pick up a passenger. They were planning to fly to Jackson, Ohio, located about 100 nm southeast of EDJ. The passenger reported that he expected to be picked up at Urbana around 1115, but the airplane never arrived.

A witness who lived about 5 miles north of West Liberty, Ohio, stated that she was in her house with the window open when she heard an airplane approaching about 1115. The airplane sounded loud like it was just above the treetops. The engine sounded fine with no missing or sputtering. She stated that the airplane was "…too low. Way, way too low."

A witness who lived across the road from where the airplane crashed reported that he heard an airplane approaching at a low altitude, but he thought initially it was a 4-wheel all-terrain vehicle. He heard the engine go silent three times, and then it revved back up twice. He saw a glimpse of the airplane through the window, and it was in a 75 degree nose low attitude. He stated that he did not recognize it as an airplane until it impacted the ground. He reported that the sky was overcast with uneven low clouds, and that the fog had cleared earlier in the morning.

A witness, who was about 3/4 of a mile northeast of the accident site, stated that he observed the airplane performing a vertical loop. He saw the airplane complete the 360 degree loop, and then he observed the airplane go into a "direct vertical climb, reach its pinnacle, and begin to fall tail first with a partial spin." He stated that there seemed to be a loss of sound from the engine sometime during the climb, but then it re-engaged as the airplane turned nose down. He lost sight of the airplane behind trees. He heard a "thud" and 15 seconds later observed a black mushroom cloud appear above the tree line.

There were no communications recordings with any Federal Aviation Administration facility. PERSONNEL INFORMATIONThe 51-year-old pilot held a private pilot certificate with a single-engine land rating. He was not an instrument rated pilot. He held a third class medical certificate that was issued on August 29, 2010, with no limitations listed. The pilot's logbook indicated that he had a total of 591 flight hours, which included 399 flight hours in the accident airplane. His last flight review was conducted on September 2, 2011.

The pilot's logbook indicated that the airplane was flown 3 hours since the annual inspection in May. The pilot purchased the accident airplane in 2006. METEOROLOGICAL INFORMATIONAt 1120, the surface weather observation at EDJ, located about 7.3 nm north of the accident site, was: winds 360 degrees at 3 knots; visibility 3 miles; overcast ceiling at 600 feet; temperature 16 degrees Celsius (C), dew point 16 degrees C; altimeter 29.91 inches of mercury (Hg).

The airport elevation at EDJ is 1,122 feet.

The elevation at the Grimes Field Airport (I74), Urbana, Ohio, and located 15 nm south of EDJ is 1,068 feet. AIRPORT INFORMATIONThe airplane was a single-engine Cirrus SR22, serial number 1159, manufactured in 2006. The engine was a Continental 310-horsepower IO-550N engine, serial number 917371. The airplane seated four and had a maximum gross weight of 3,400 pounds. The airplane was certificated in the normal category and was not designed for aerobatic operations. Aerobatic maneuvers and spins are prohibited. The last annual maintenance inspection was conducted on May 2, 2011, with a total time of 682.5 hours. The pilot's logbook indicated that the airplane was flown 3 hours since the annual inspection in May. The pilot purchased the accident airplane in 2006. WRECKAGE AND IMPACT INFORMATIONThe accident site was located in a cornfield about one mile west of West Liberty, Ohio. The examination of the initial point-of-impact and the debris field revealed that the airplane impacted the terrain on a magnetic heading of about 110 degrees. The cut through the high corn made by the airplane's landing gear, fuselage, and wings indicated that it was in about 45 degrees nose down attitude with a 10-degree left wing low attitude at impact.

The initial ground impact crater was located about 16 feet from the first row of corn that was struck. The crater was about 8 feet long, 6 feet wide and 8 inches deep. One propeller blade and the nose landing gear leg were located near the crater. The wreckage debris field, which was 27 feet wide, extended east about 120 feet from the initial impact. The main wreckage came to rest about 90 feet from the initial point-of-impact. The fuselage was destroyed by impact forces and postimpact fire.

The wings, horizontal stabilizer, and vertical stabilizer exhibited impact and fire damage. Aileron control cable continuity was confirmed. The flap actuator shaft was found in the "Flaps-Up" position. The left and right landing gear assemblies were separated from the wings. The rudder cable continuity was confirmed from the elevator control torque tube to the rudder bellcrank at the fuselage station 306 bulkhead. The elevator cable continuity was confirmed from the elevator control torque tube to the elevator bellcrank at the fuselage station 306 bulkhead. The pitch trim motor was in about the neutral pitch trim position. Cockpit documentation was not possible due to extensive impact and fire damage.

The Cirrus Airframe Parachute System (CAPS) rocket motor was located left of the debris field about 43 feet from the initial point-of-impact. A visual examination of the rocket motor revealed that the rocket motor propellant was expended. The parachute assembly was located about 50 feet from the initial point-of-impact and outside the left side of the debris field. The packed parachute was partially separated from the "D-bag."

The engine exhibited impact and fire damage. The cylinders remained attached to the engine. The top spark plugs were removed and exhibited normal operating signatures when compared with the Champion Check-A-Plug chart. The cylinders were inspected using a lighted boroscope, and the combustion chambers exhibited light colored combustion deposits. The engine was rotated and continuity was established from the rear of the engine to the forward nose seal area of the crankshaft. Thumb compression was obtained on cylinders one, three, five, and six. Cylinders two and four had impact damage to the bottom of the cylinders and the push rod housings. The crankshaft was fractured between the propeller flange and the engine nose seal. The crankshaft fracture surface exhibited 45 degree shear lip fractures and spiral cracking.

The examination of the propeller revealed that the crankshaft propeller flange remained attached to the propeller hub. Two of the propeller blades were fractured from the propeller hub at the base of the blades. The third propeller blade remained attached to the propeller hub. All three blades exhibited multi-directional bending, chord-wise scratching, and gouges in the leading edges.

The Avidyne Primary Flight Display (PFD) and the Avidyne Multi-Function Display (MFD) installed in the accident airplane received extensive heat and impact damage. Two surface mounted flash memory chips recovered from the PFD, and the memory card recovered from the MFD were sent to the National Transportation Safety Board (NTSB) Vehicle Recorder Division for examination. ADDITIONAL INFORMATIONThe MFD is not equipped with an ON/OFF switch. To disconnect the MFD from electrical power, the MFD circuit breaker located on the Avionics Non-Essential bus would need to be pulled. The circuit breaker panel is located within the pilot's reach next to the central pedestal. Turning off the main avionics switch would disconnect the MFD from electrical power; however, all avionics equipment would be turned off as a result.

The MFD generates new data files for each power-on cycle. The oldest record is dropped and replaced by a new recording once the storage limit has been reached. MFD data are sampled every six seconds, and are recorded to memory once every minute. If an interruption of power occurs during the minute between MFD memory-write cycles, data sampled during that portion of a minute are not recorded.

The transponder is equipped with an ON/OFF switch. The transponder's circuit breaker is located on the Avionics Non-Essential bus. MEDICAL AND PATHOLOGICAL INFORMATIONAn autopsy of the pilot was performed at the Montgomery County Coroner's Office in Dayton, Ohio, on September 9, 2011. The "Cause of Death" was listed as multiple blunt force injuries. A Forensic Toxicology Fatal Accident Report was prepared by the FAA Civil Aerospace Medical Institute. The results were negative for carbon monoxide, cyanide, and ethanol. The following substances were identified in the toxicology report: 19.73 (ug/ml,...
