Beechcraft 90 King Air

The emergency medical services (EMS) airplane was destroyed by terrain impact and post impact fire about 7 nautical miles (nm) west of its destination airport, Dodge City Regional Airport (DDC), Dodge City, Kansas. The 14 Code of Federal Regulations Part 91 positioning flight departed the Wichita Mid-Continental Airport (ICT), Wichita, Kansas, about 0215 central standard time and was en route to DDC. Night visual meteorological conditions prevailed when the accident occurred about 0257 central standard time. The flight had been on an instrument flight rules (IFR) flight plan, but the pilot cancelled the IFR flight plan about 34 nm east of DDC and initiated a descent under visual flight rules. Radar track data indicated that the airplane maintained a magnetic course of about 265 degrees during the flight from ICT to DDC. The rate of descent was about 850 to 950 feet per minute. During the descent, the airplane flew past the airport on a 270 degree course. Witnesses in the area reported hearing the engine noise of a low-flying airplane followed by the sound of impact. One of the witnesses described the engine noise as sounding like the engines were at "full throttle." The on-site inspection revealed that the airplane impacted the terrain in a gear-up, wings-level attitude. The inspection of the airplane revealed no anomalies to the airframe or engines. A review of the pilot's 72-hour history before the accident revealed that it had been 14 hours and 32 minutes from the time the pilot reported for duty about 1225 central standard time until the time of the accident. It had been 20 hours 57 minutes from the time the pilot awoke (0600) on the morning before the accident until the time of the accident. No evidence of pilot impairment due to carbon monoxide, drugs, or medical incapacitation was found. The accident occurred during a time of day that was well past the pilot's normal bedtime and also at a time of day when the physiological need to sleep is especially strong. The findings from a Safety Board's human performance analysis indicates that the pilot was likely fatigued. A review of 14 CFR 135.267 indicated that the pilot had adhered to the flight time limitations and rest requirements specified in the regulation.

The instrument rated pilot received three weather briefings on the date of the accident from the Miami Automated Flight Service Station. The pilot obtained his IFR clearance while airborne, was advised to climb to 9000 feet mean sea level (MSL), then later advised to descend and maintain 2000 feet, and to fly heading 030 degrees. Radar data indicates that following the instruction from the controller, the airplane made a right descending turn to a southeasterly heading, followed by a left turn to an easterly heading where the airplane was lost from radar while at 2,200 feet mean sea level. The crash was located 138 degrees and .38 nautical mile from the last radar target. Between 1631:04, and 1631:16, the airplane descended from 7,600 to 6,100 feet. Between 1631:16, and the last radar target 12 seconds later at 1631:28, the airplane descended 3,900 feet. Weather radar data indicates the airplane encountered video integrator and processor (VIP) Level 2, or "moderate intensity" echoes in the area of the in-flight loss of control. Approximately 10 and 20 miles east-northeast through southeast of the accident site, maximum echoes of VIP Level 5 to 6, or "intends to extreme intensity" echoes were noted. The strongest reflectivities were located 20 miles east of the accident site. Disintegration of the airplane was noted; there was no evidence of in-flight, or post crash fire of any recovered components. The full span of the left wing, left aileron, left horizontal, and left elevator were accounted for. A section of the right wing and right outboard flap was identified; the right wing was fragmented. Examination of the engine and propellers revealed no evidence of preimpact failure or malfunction. No determination was made whether the pilot met the instrument recency of experience requirement of 14 CFR Part 61.57 (c).

The airplane lost engine power during descent. The 1,127-hour pilot elected to perform emergency engine out procedures and prepared for an emergency landing. After impact, the pilot observed the right engine nacelle engulfed in flames, which then spread to the fuselage. Review of the engine logbook revealed the engine was being operated in excess of 1,000 hours of the manufacturer's recommended time between overhauls of 3,600 hours. The airplane received post-impact fire damage. Further examination of the engine revealed severe fire damage, but no mechanical deficiencies.

According to the pilot, prior to takeoff, he had the airplane fueled with 20 gallons of fuel in each wing for the short cross-country flight. After takeoff the airplane climbed to an altitude of 9500 feet. During the downwind to the arrival airport the right engine lost power. Shortly after the left engine lost power, the pilot made an emergency off-airport landing. Examination of the fuel system revealed that the fuel tanks were not beached, and there was a small amount of residual fuel in the fuel tanks. The exact amount of fuel onboard the airplane at the time of the departure was not determined.

The pilot reported that he maneuvered for a left hand downwind leg for landing from the east to west. The pilot set up his downwind leg at 8,400 feet mean sea level putting him at what would have been 1,000 feet above the airport elevation of 7,411 feet. The pilot reported it was very dark and he could see the airport, but could not see the terrain. The pilot reported that suddenly he saw the ground. The airplane impacted the terrain and came to rest. The pilot reported that the airplane was experiencing no malfunctions prior to the accident. The airplane accident site was on the snow-covered edge of a mountain ridge at an elevation of 8,489 feet. An examination of the airplane's systems revealed no anomalies. Published terminal procedures for the runway indicated high terrain of 8,739 feet south-southeast of the airport. The published airport diagram for the airport directs right traffic for the pattern to runway 27.
