HISTORY OF FLIGHT
On February 16, 2008, approximately 1845 central standard time, a Cessna 414A, N41LP, owned by Bajaj Holdings LLC, and piloted by a private pilot, was destroyed when it impacted terrain after departing Lloyd Stearman Field Airport (1K1), Benton, Kansas. A post impact fire ensued. Night instrument meteorological conditions prevailed at the time of the accident. The personal flight was being conducted under the provisions of Title 14 Code of Federal Regulations Part 91 without a flight plan. The private pilot and his passenger were fatally injured. The cross country flight was repositioning from 1K1 to Colonel James Jabara Airport, Wichita, Kansas (AAO) to pick up one additional passenger. The final destination was Austin, Texas.
The Butler County Sheriff's Department took witness statements from four individuals. The National Transportation Safety Board (Safety Board) Investigator in Charge (IIC) interviewed two witnesses and inspectors with the Federal Aviation Administration (FAA) interviewed two witnesses. These witnesses were located to the south, east, and west of the impact location. According to these witnesses, the airplane departed runway 35 (2,613 feet by 60 feet; asphalt). The airplane was observed flying in and out of the clouds. Several of the witnesses observed the airplane initiate a turn to the west. One witnesses commented that it was dark but he could still see the silhouette of the airplane. He observed the airplane descend below the trees. All of the witnesses reported flames and "fireballs."

WRECKAGE AND IMPACT INFORMATION
The accident site was located in an open field, just south of a line of trees, and railroad tracks. The accident site was at an elevation of 1,367 feet msl.
The initial impact point, as identified by the Safety Board IIC, was located towards the tops of several trees, approximately 4,500 feet northwest of the airport. Torn fiberglass consistent with the left winglet and red lens fragments were found in several trees and scattered on the ground directly below those trees. Several fresh broken tree branches were located on the ground below.
A second impact point was located in an open wheat/cornfield (546 feet southwest of initial impact point). Green lens fragments and torn fiberglass were located within the ground scar. A debris path extended from the second impact point to the main wreckage, along a magnetic bearing of 245 degrees. Torn metal and fiberglass, the right wing tip, a portion of the right wing, both gear doors, portions of both engine mounts, the left inboard flap, and both engine cowlings were located within the debris path.
Both propeller assemblies separated from their respective engines. The left propeller assembly included all three propeller blades. The blades were labeled "A", "B", and "C" for identification purposes only. Blade A was bowed aft 30 degrees, six inches outboard from the hub. The blade exhibited leading edge knicks and polishing. The tip of blade B was curled and the blade was bowed aft, exhibiting leading edge polishing and several knicks. Blade C was twisted slightly. The spinner on the left propeller assembly was torn and exhibited circular crushing.
The right propeller assembly included all three propeller blades. The blades were labeled "D", "E", and "F" for identification purposes only. Blade D exhibited S-bending and was bowed aft 20 degrees. The blade exhibited leading edge knicks, polishing and chordwise scratching. Blade E exhibited S-bending. Blade F exhibited S-bending and leading edge polishing. The outer nine inches of the tip was bent aft 90 degrees. The spinner on the right propeller assembly was crushed and torn.
The main wreckage came to rest 546 feet southwest of the initial impact point. The main wreckage consisted of the fuselage, empennage, portions of the left and right wings, and both engine assemblies. The left wing, to include the left engine, outboard flap, and aileron, came to rest inverted, under the fuselage of the airplane. The leading edge of the left wing was crushed aft and torn. The wing was charred, melted, and partially consumed by fire.
The right wing separated from the fuselage and came to rest southwest of the main wreckage. The landing gear assembly appeared to be down and locked. The flaps and aileron separated from the wing assembly.
The empennage, to include the horizontal stabilizer, vertical stabilizer, rudder, and elevator, separated partially from the fuselage. The vertical stabilizer and rudder were covered in mud but otherwise unremarkable. The outboard 25 inches of the left horizontal stabilizer was bent and wrinkled. The elevator on the left side separated at the outboard attach point and was bent at midspan. The trailing edge of the right side horizontal stabilizer was wrinkled. The elevator tip was bent down and the leading edge was wrinkled.
Control continuity was confirmed for all primary flight controls. The rudder trim was measured at 2.0 inches; according to Cessna this is consistent with zero degrees. The elevator trim was measured at 0.7 inches; according to Cessna this is consistent with 15 degrees tab down (nose up). The aileron trim was measured at 0.6 inches; according to Cessna this is consistent with zero degrees.
The fuselage, to include the cabin, six seat assemblies, and the instrument panel, came to rest on an approximate heading of 200 degrees. The upper portion (roof) of the fuselage was destroyed. The instrument panel was charred, melted, and partially consumed by fire. The front two seats in the cabin were destroyed. The aft four seats were charred, melted, and partially consumed by fire.
Both engines were examined revealing signs of normal operation.
MEDICAL AND PATHOLOGICAL INFORMATION
The autopsy on the pilot was performed by the Sedgwick County Regional Forensic Science Center - Coroner Division, Wichita, Kansas, on February 18, 2008, as authorized by the Butler County Coroner's office. The autopsy revealed the cause of death as blunt force trauma.
During the autopsy, specimens were collected for toxicological testing to be performed by the FAA's Civil Aerospace Medical Institute, Oklahoma City, Oklahoma (CAMI Reference #200899931001). Tests for carbon monoxide and ethanol were negative. Cetirizine was detected in the blood and urine and 0.8 ug/ml of cyanide was detected in the blood. Cetirizine is an antihistamine, often known by the trade name Zyrtec, that became available without a prescription in January 2008.
According to the pilot's application for third class medical certification in May of 2005, he indicated "yes" in response to "hay fever or allergy." He indicated "no" in response to current use of any medication.
