McEwen, TN, USA

Aircraft #1

N43334

Piper PA-28-181

Analysis

The pilot's original destination was Clarksville, Tennessee. However, because of adverse weather conditions in Clarksville, the pilot diverted to Waverly, Tennessee. The pilot contacted the Nashville automated Flight Service Station at about 2200 and again at about 0100 for a weather brief. The pilot limited the brief by only asking what Ft. Campbell, was reporting for visibility. At both times Ft. Campbell, Kentucky was reporting less then three miles visibility and fog. Shortly after 0130, the non-instrument rated private pilot, initiated VFR flight into IMC conditions. The airplane was last seen on radar at about 0155 in the vicinity of the accident site, circling, at about 1600 feet mean sea level. Examination of the wreckage found that the airplane had cartwheeled left wing first, then the nose, followed by the right wing, until it came to rest against a tree line. Further examination did not reveal evidence of mechanical malfunction, and there was no evidence of pilot impairment or incapacitation.

WRECKAGE EXAMINATION Examination of the wreckage on-scene found that the airplane rested next to a tree line bordering a cow pasture, about 5 miles southeast of the Waverly Airport. The left wing, aileron and flap had separated at the wing root. The outboard section of the wing spar was bent aft. The outboard leading edge of the wing had impact damage and was compressed aft and upward. The fuel cap was in-place and intact. The left main landing gear was found separated from the wing. The left aileron was separated into two sections, including a missing outboard tip. The aileron was attached to the middle hinge only. The bell crank was attached to its attachment points, and the stops were in-place and intact. The push pull tube from the bell crank to the aileron was damage and separated from its attachment point. Both aileron cables were attached to the bell crank and separated near the wing root. The primary cable was found cut. The balance cable was frayed and unwound. The flap was separated into two sections. The inboard section was attached to the inboard hinge. The outboard section was separated from its attachments. The right wing was separated at the wing root. The outboard leading edge was buckled aft to the main spar, and the outboard tip was destroyed. Fuel, blue in color, was found in the breached fuel tank. The fuel cap was in-place and intact. The right main gear had impact damage. The right aileron remained attached to all three of its attachment points. The bell crank was separated from its attachment points. The push pull rod from the bell crank to the aileron was separated. The aileron cables were attached to the bell crank and separated near the wing root. The cable separation was frayed and unwound. The flap was attached to the inboard hinge only, and the flap was separated into two sections. The vertical stabilizer and rudder sustained impact damage. The leading edge of the vertical stabilizer had impact damage. The rudder was attached to the middle attachment point and to the rudder horn. The stops were in-place and intact. The rudder cables were attached to the rudder horn and separated near the baggage area where the fuselage had separated. The rudder cables were attached to the rudder bar and separated near the cabin area. The cable separation was frayed and unwound. The horizontal tabulator was damaged. The left side of the tabulator had leading edge circular impact damage. Approximately 18 inches of the left outboard tabulator was separated and destroyed. The trim tab mechanism measured 3/4 of an inch and displayed 4 threads, which positions the tab in the neutral position. The tabulator stops were in-place and intact. The tabulator cables were attached to the balance weight and separated at the aft baggage compartment. The cable separations were strayed and unwound. The tabulator cables were attached to the "T" Bar and separated near the cabin area. The fuselage had separated near the aft baggage compartment. The flap handle was separated from its attachment point. The fuel selector was separated from its attachment points and was selected to the right tank position. The fuel selector was field tested by blowing air through the valves with no obstructions noted. Examination of the engine revealed that it was separated from the airframe structure and all the tubular mounts were broken. Then engine controls were destroyed. Initial visual examination of the engine revealed no outward anomalies. Detail examination of the engine including partial disassembly found the spark plugs, valve covers, oil filter, and oil suction screen unremarkable. Rotation of the crankshaft established internal gear and valve train continuity. All four cylinders developed thumb compression during crankshaft rotation. Bore scope examination of the engine revealed no primacy anomalies. The carburetor and fuel pump were damaged, separated. Several fuel hoses were broken. The carburetor was opened for examination, the bowl was clean, the nozzle was clear, one float was partly collapsed. No fuel was found within the engine components. Both fuel tanks were ruptured.

The instrument vacuum system pump was found impact damaged but the drive coupling was intact, inspection of the internal vanes revealed no anomalies. The propeller assembly was attached to the crankshaft flange. The #1 blade was heavily damaged, the outboard section was twisted, and approximately ten inches of blade material was torn off, and not located or recovered. The #2 blade exhibited tensional bending, and heavy leading edge nicks at the tip section was noted. Both blades had heavy scoring and abrasions. MEDICAL/PATHOLOGICAL INFORMATION An autopsy examination of the pilot and passengers was conducted by the Department of the Army, 31st Military Police Detachment (CID) (Air Assault) 3D Military Police Group Criminal Investigation Division (CID) USACIDC, Fort Campbell, Kentucky. The autopsy examination established the manner of death for the pilot and passenger as, accidental, and the cause of death as multiple blunt force trauma. A post accident toxicological examination was performed by the Federal Aviation Administration (FAA) Civil Aero medical Institute, in Oklahoma City, Oklahoma. The toxicology report on the pilot revealed no ethanol was detected in the muscle, 25(mg/do, mg/hg) ethanol detected in kidney and 10(mg/do, mg/hg) acetaldehyde detected in kidney. No drugs were detected in the kidney. The low levels of ethanol and acetaldehyde detected in the kidney is likely a result of post-mortem production. ADDITIONAL INFORMATION Radar data was recovered from Memphis Air Traffic Control Center in Memphis, Tennessee. A review of the data and a controllers statement found that the airplane was between 1,600 feet and 1,700 feet, and according to the controller the airplane was "circling, disoriented, or returning to Waverly, Tennessee." The wreckage was released to the owners representative on August 28, 2002, US Aviation Underwriters.

Probable Cause and Findings

The pilot initiated a VFR flight into known IMC conditions which resulted in a loss of control of the airplane due to spatial disorientation. Factors were the low ceilings.
