Aircraft #1

N6085R

Cessna 172RG

Analysis

The airplane was destroyed when it impacted the ground and subsequently burned. The airplane was being operated by a non-instrument rated private pilot who was fatally injured during the accident. Weather reporting stations near the accident site recorded instrument meteorological conditions with low ceilings and reduced visibilities. There was no record of the pilot having received a weather briefing or filing a flight plan for the flight. On-scene examination of the airplane and its systems did not reveal any evidence of a pre-impact failure.

Factual Information

HISTORY OF FLIGHT On October 9, 2005, about 1945 eastern daylight time, a Cessna 172RG, N6085R, operated by a non-instrument rated private pilot was destroyed when it impacted terrain near Union City, Ohio. The 14 CFR Part 91 personal flight was operating in instrument meteorological conditions without a flight plan. The pilot who was the sole occupant was fatally injured. The flight originated from Coldwater, Michigan, at an unconfirmed time and was en route to Lexington, Kentucky. PERSONNEL INFORMATION According to Federal Aviation Administration (FAA) records, the pilot held a private pilot certificate with an airplane single-engine land rating. He did not have an instrument rating. His most recent third class medical certificate, issued on March 29, 2004, listed no limitations. The pilot reported having 400 hours of total flight experience as of the date of the medical examination. AIRCRAFT INFORMATION The airplane was a 1980 Cessna model 172RG, serial number 172RG0077. The airplane was a single-engine high-wing monoplane of predominately aluminum construction. The wings were strut braced and the airplane had a retractable tri-cycle landing gear. A 180 horsepower Lycoming model O-360-F1A6 engine powered the airplane. Maintenance records indicated that the airplane had accumulated a total of 6,498.5 hours total time in service as of the most recent annual inspection. The records showed that the inspection was performed on June 20, 2005. METEOROLOGICAL INFORMATION Aviation routine weather reports (METAR) were obtained for nearby airports.

WRECKAGE AND IMPACT INFORMATION The FAA and a representative of the aircraft manufacturer conducted an on-scene investigation. A global positioning system receiver was used to determine the accident site coordinates as 40-degrees, 18-minutes, 49-seconds north latitude, 84-degrees, 46-minutes, 40-seconds west longitude at an elevation was 1,085 feet above sea level. The airplane came to rest in a harvested agricultural field. All of the major airframe components and flight control surfaces were identified at the accident site. The right wing was located the farthest from the initial impact point (272 feet). The forward portion of the pitot tube and a red lens material consistent with the left navigation light lens were found within the initial impact ground scar. The fuselage was fragmented and burned from the firewall aft to the tail surfaces. The horizontal and vertical tail surfaces remained attached to the aft fuselage. The elevators and rudder remained attached to the horizontal and vertical stabilizers respectively. The left wing was located within the main wreckage and exhibited significant crushing and fire damage. The right wing was separated from the airplane and remained substantially intact. Portions of the right flap and right aileron remained attached to the wing. One of the propeller blades was found within the initial impact crater. The other propeller blade remained attached to the propeller hub. The crankshaft flange was separated from the engine and remained attached to the propeller hub. Both propeller blades exhibited chordwise scratching. One blade exhibited S-shaped bending along its length and leading edge gouges. The other blade exhibited a slight forward bend and leading edge abrasion. External examination of the engine revealed no evidence of a catastrophic failure of the engine. Examination of the spark plugs revealed no evidence of fouling or other abnormalities. The engine could not be rotated by hand. Examination of the vacuum pump revealed that the vacuum pump core had fractured into several pieces. The vanes remained intact. No indication of a pre-impact malfunction was evident. The vacuum operated directional gyro had evidence of rotational scoring on both its core and housing. Examination of the control system revealed no breaks of the control cable attachment points. Examination of the flap mechanism confirmed that the flaps were in the retracted position. The landing gear selector was found in the up position. No evidence of a pre-impact failure of the airplane or its systems was found during the on-scene investigation. MEDICAL AND PATHOLOGICAL INFORMATION An autopsy was performed on the pilot by the Montgomery County Ohio Coroner's Office. A Final Forensic Toxicology Fatal Accident Report prepared by the FAA listed the following findings: 31 (mg/dL, mg/hg) ETHANOL detected in Muscle NO ETHANOL detected in Brain 1 (mg/dL, mg/hg) N-BUTANOL detected in Muscle -Notes: -The ethanol found in this case is from sources other than ingestion. TESTS AND RESEARCH A portable GPS unit was found within the accident wreckage. The unit was identified as a Garmin GPSmap 195, serial number 51251177. The unit was shipped to the manufacturer to attempt to extract stored flight data. According to a report from the manufacturer, the data could not be retrieved due to the damage the unit had received. The aircraft owner was contacted during the course of the investigation. He indicated that he had known and had learned to fly with the accident pilot. He also revealed that he had been on board the airplane until its arrival in Battle Creek, Michigan. He was asked if the accident pilot had received a weather briefing prior to departing Battle Creek to which he answered no. Further questioning about the accident pilot's knowledge relating to in-flight weather and radar services revealed that the accident pilot did not use these services. An inquiry of Flight Service Station (FSS) and Direct User Access Terminal System (DUATS) records revealed no records of a flight plan or weather briefing related to the accident airplane. A fueling record from a fixed base operator at the Brach County Memorial Airport in Coldwater, Michigan, indicated that N6085R was fueled with 47.49 gallons of 100LL aviation gasoline at 1823 local time on October 9, 2005. ADDITIONAL INFORMATION The FAA and Cessna Aircraft were parties to the investigation.

Probable Cause and Findings

The pilot's failure to perform a preflight weather evaluation which led to his inadvertent flight into instrument meteorological conditions and his spatial disorientation. The low ceilings and the dark night were contributing factors.
