HISTORY OF FLIGHT On October 1, 1994, about 1900 central daylight time, a Cessna 150G, N3654J, was destroyed while maneuvering near Lamberton, Minnesota. The solo private pilot sustained fatal injuries. The flight originated about 1857 on a farm road near the accident site with a planned destination of St. James, Minnesota. Visual meteorological conditions prevailed for the personal flight, conducted under 14 CFR Part 91. No flight plan was filed. According to witnesses, the pilot had been visiting with relatives, celebrating his sister's 25th wedding anniversary. He took off, as he had previously landed, from the gravel road next to his brother-in-law's farm. After takeoff, he made one pass north to south and a second pass west to east just south of the farm house. Witnesses stated the airplane was at an altitude of a few hundred feet. As the pilot pulled up sharply, the nose of the airplane dropped, and the airplane began rotating to the right. They reported the engine noise decreased but the engine continued to run during the descent. The airplane impacted the terrain in a plowed field. WRECKAGE AND IMPACT INFORMATION The NTSB on-scene investigation began on October 2, 1994, at 0930. The wreckage was located in a field north of the Ervin Runk farm and east of the Donald Runk farm. A five by three foot crater, six inches deep was located two feet in front of the nose of the airplane. The left wing was separated from the main wreckage and was located 27 feet to the south, oriented perpendicular to the fuselage. The forward fuselage was crushed upward and aft to the aft door frames. The empennage, aft of the cabin area, was bent 90 degrees to the right. The right wing was crushed aft at a thirty degree angle from midspan out to the tip. One blade of the propeller was bent aft approximately 30 degrees at midspan. The tip of the other blade was bent slightly forward. Minor torsional bending was evident. Slight charring to surrounding vegetation was evident beneath the engine. Witnesses reported they had extinguished a small postimpact fire using a hand held fire extinguisher. The spark plugs were black and coated with carbon. The left magneto sparked when it was rotated by hand. The right magneto was partially melted and could not be functionally tested. No evidence of preimpact mechanical malfunction was discovered. Examination of engine and flight control system continuity revealed no anomalies. A fuel sample from the left wing tank revealed clean, clear, green colored fuel. The sample smelled similar to automobile fuel. Testing of the fuel with a field test kit revealed it contained no water and greater than five percent alcohol. MEDICAL AND PATHOLOGICAL INFORMATION Autopsy of the pilot was conducted at the Immanuel-St. Joseph's Hospital, 1025 Marsh Street, P. O. Box 8673, Mankato, MN 56002- 2626. Toxicological testing was negative for all tests conducted except 0.153 (ug/ml, ug/g) Chlorpheniramine detected in liver fluid and 0.478 (ug/ml, ug/g) Chlorpheniramine detected in spleen fluid. According to a NTSB National Resource Specialist, the therapeutic level for Chlorpheniramine is .016 to .070 (ug/ml, ug/g) in blood specimens. Chlorpheniramine is listed in the Physicians' Desk Reference as an active ingredient in many nonprescription cold and allergy medications. Medications containing Chlorpheniramine warn "use caution when driving a motor vehicle or operating heavy machinery" ADDITIONAL INFORMATION Parties to the investigation were the Federal Aviation Administration Flight Standards District Office, Minneapolis, Minnesota, and Cessna Aircraft Corporation, Wichita, Kansas. Following the on-scene portion of the investigation, the wreckage was released to Mr. Dewayne Malmgron, the manager of the St. James Airport.
