NTSB description

HISTORY OF FLIGHT On February 16, 2000, at 0748 central standard time, a mid-air collision occurred between a Cessna 182M, N91994, and a Cessna 208B, N9505B, while both airplanes were maneuvering near the McAlester Regional Airport, McAlester, Oklahoma. The Cessna 182 was destroyed, and the Cessna 208 sustained substantial damage. The non-instrument rated private pilot of the Cessna 182 sustained fatal injuries, and the airline transport rated pilot of the Cessna 208 was not injured. There were no passengers in either airplane. The Cessna 182, which was registered to the private pilot, was operating under 14 Code of Federal Regulations (CFR) Part 91 as a personal cross-country flight; the flight departed from Neosho, Missouri, with a planned destination of Carrizo Springs, Texas, and no flight plan was filed. After receiving an in-flight weather report of instrument meteorological conditions along his route of flight, the pilot of the Cessna 182 elected to divert to McAlester Regional Airport. The Cessna 208, which was registered to MartinAire Inc., of Carrollton, Texas, was operating under 14 CFR Part 135 as a non-scheduled cargo flight (MartinAire 633) for which an IFR flight plan was filed; the flight departed from the McAlester Regional Airport at 0745 and was en route to Hugo, Oklahoma. Visual meteorological conditions prevailed at the time of the accident.

According to the pilot of the Cessna 208, as he was taxiing for takeoff, he heard the pilot of the Cessna 182 make a radio call on the non-towered airport's common traffic advisory frequency (123.0) asking for an airport advisory. The pilot of the Cessna 208 responded to the Cessna 182 pilot, stating that the winds were from 020 degrees at 15 knots gusting to 23 knots, and he was going to depart from runway 01. The Cessna 208 pilot reported that he did not hear any further radio calls from the Cessna 182. Upon reaching runway 01, the pilot of the Cessna 208 determined that there "were no other planes in the pattern and nobody on the radio," and announced his intentions to takeoff from runway 01. He made his takeoff, climbed straight-out until the airplane reached 500 feet agl and then turned the airplane left onto the crosswind leg. He maintained the climb until the airplane reached approximately 1,000 feet agl, leveled out, and turned left onto the downwind leg. He continued on the downwind leg until the airplane was "past mid-field." Prior to turning left to a heading of 160 degrees on course for Hugo, he looked to the left to clear the area and "was surprised to see an object coming closer." He determined that the object "was a high-wing Cessna coming from slightly above and behind [his] left wing-tip," which was descending toward his cockpit. He reduced power, rolled right and nosed down. He stated that the Cessna 182 "turned left as in a normal x-wind to downwind turn [and] did not take evasive action." He further stated that the Cessna 182 "flew over [his] cockpit and the 2 planes hit in a glancing blow." Subsequently, the Cessna 182 impacted the ground, and the Cessna 208 returned to the airport and landed on runway 01.

According to witnesses, prior to the collision the "Cessna 208 was in front with the Cessna 182 above and behind," and it appeared as if the "smaller plane accelerated toward the big plane." One witness reported that he observed "2 planes collide, touching wings." Following the collision the two witnesses observed a piece of the Cessna 182's structure, which they described as a wing, separate and, subsequently, the airplane entered a descent, began "spinning," and impacted the ground. They reported that the Cessna 208 continued flying and returned to the airport.

At the time of the last radar return, the target was approximately 2.5 nautical miles northeast of the McAlester Regional Airport.

METEOROLOGICAL INFORMATION

At 0753, the weather observation facility located at the McAlester Regional Airport reported the visibility as 10 miles, winds from 020 degrees at 16 knots gusting to 19 knots, ceiling 1,900 feet overcast, temperature 48 degrees Fahrenheit, dewpoint 36 degrees Fahrenheit, and altimeter 30.23 inches of mercury.

WRECKAGE AND IMPACT INFORMATION

The Cessna 182 came to rest approximately 2 miles south of the airport, adjacent to a railroad track. A GPS receiver recorded the wreckage location at 34 degrees 51.77 minutes north latitude and 095 degrees 49.02 minutes west longitude. The linear energy path was 150 feet in length from the initial impact point with trees to the final component along the path, and was oriented on a heading of 200 degrees magnetic. The initial impact point with the ground was a crater 20 feet from the initial impact point with trees, and contained the left wing strut, the propeller blades and hub, the inboard section of the left aileron, and the left cabin door. The engine came to rest 27 feet from the initial impact point with trees, a portion of the cabin (from mid-cabin aft), right wing, empennage, and tail remained intact and came to rest approximately 50 feet from the initial impact point with trees. The last component of the airplane located along the energy path was identified as one of the two main landing gear wheels. The major structural components of both wings were identified along the wreckage path. No evidence of contact with the Cessna 208 was identified during the examination of the Cessna 182.

During the examination of the Cessna 182, the flap actuator was measured and the flap setting determined to be extended 20 degrees. Flight control continuity could not be established as result of impact damage. The cabin (mid-cabin forward) and cockpit were consumed by fire. The flight and engine instruments were destroyed by impact forces and fire. The propeller blades and hub assembly were examined. One propeller blade separated at the hub, and the second blade exhibited "S" bending and had gouges in the leading and trailing edges.

Damage to the Cessna 208 was confined to the outboard portion of the left wing and left aileron, which were bent upwards approximately 60 degrees, 5 feet inboard from the wing-tip. Chordwise scratching and white paint transfer marks were observed on the outermost 12 inches of the bottom skin of the left wing. This section of wing skin was crushed upward with the damage increasing in severity from the wing trailing edge toward the wing leading edge. The wing-tip cap was crushed inward, and the outermost 12 inches of the left wing leading edge were crushed and torn.

MEDICAL INFORMATION

An autopsy was performed on the pilot of the Cessna 182 by the Office of the Chief Medical Examiner in Tulsa, Oklahoma. Toxicological test results for the pilot of the Cessna 182 revealed that diltiazem, a prescription drug for the control of blood pressure, was detected in the lung and muscle tissue; additionally the results revealed no concentration of ethanol. Post accident drug test results reported by the SAH Occupational Health-Reno, in Oklahoma City, Oklahoma, for the pilot of the Cessna 208, were negative for amphetamine, cocaine, phencyclidin, cannabinoid, and opiates.

ADDITIONAL INFORMATION

The Cessna 182 was released to the owner's representative on February 17, 2000, and the Cessna 208 was released to MartinAire Inc., on February 18, 2000, following the on-scene examination of both airplanes.
