Aspen, CO, USA
N4377V
Cessna 195
The pilot flew the airplane from the departure airport (field elevation of 7,815 feet msl) to a point approximately 3 miles north before turning southeast and flying up a valley. Local pilots stated that the normal procedure for departing the airport was to fly north 8 to 10 nautical miles north before turning into a different valley. The valley where the wreckage was located was surrounded by rapidly rising terrain on each side and terminated at a mountain ridge with elevations up to 12,700 feet msl. The accident site was located at an elevation of 9,860 feet. The wreckage energy path was oriented almost opposite the direction needed to fly up the valley, indicating that the pilot attempted to reverse direction and fly out of the valley. No anomalies were noted with the airframe or engine that would have prevented normal operation of the aircraft. The density altitude at the time of the accident was calculated to be 10,518 feet.
HISTORY OF FLIGHT On July 8, 2000, at approximately 1120 mountain daylight time, a Cessna 195 single-engine airplane, N4377V, was destroyed when it collided with terrain while maneuvering 7.4 miles northeast of Aspen, Colorado. The airplane was registered to and operated by the airline transport pilot. The pilot and his three passengers received fatal injuries. Visual meteorological conditions prevailed and a visual flight rules flight plan was filed, but not activated, for the 14 Code of Federal Regulations Part 91 personal flight. The flight departed the Aspen-Pitkin County Airport (ASE) at 1106, and was enroute to the Front Range Airport, Watkins, Colorado, at the time of the accident. According to family members, the pilot flew the airplane from the Front Range Airport to ASE earlier on the morning of the accident. After having breakfast at Aspen, the pilot and his passengers boarded the airplane for the return flight to Watkins. Radar data depicted the airplane departing ASE, flying north down the Roaring Fork River Valley, then turning right to fly southeast up the Woody Creek Valley. The last radar return (39 degrees 14 minutes and 47.3 seconds North and 106 degrees 49 minutes and 52.6 seconds West) depicted the airplane at 8,388 feet msl (approximately 148 feet above the terrain). On July 9, 2000, at 1630, a missing aircraft report was issued by the FAA based on family concerns when the aircraft did not arrive at the Front Range Airport. On July 10th at 0600, the Civil Air Patrol commenced an aerial search. Approximately 0745, the search airplanes found the accident site in the Woody Creek Valley, approximately 5.5 miles east of the location of the last radar return. PERSONNEL INFORMATION The pilot held an airline transport pilot certificate with an airplane multi-engine land rating and type ratings in the Boeing 737, 757, 767, and 777 aircraft. He also held a commercial pilot certificate with an airplane single-engine land rating, and current flight instructor ratings for single-engine and instrument airplanes. The pilot was issued a first class medical certificate on March 2, 2000, with the limitation "must wear corrective lenses and possess glasses for near and interim vision." According to the March 2000 medical application, the pilot reported that he had accumulated a total of 5,800 flight hours. It is not known how many hours were accumulated in the accident airplane; however, the pilot had been the registered owner of the airplane since July 7, 1998. AIRPORT & SURROUNDING AREA INFORMATION The ASE airport is located north of the city of Aspen at an elevation of 7,815 feet msl. A review of the Airport Facility Directory entry for ASE revealed that it stated that "unique VFR [visual flight rules] departure procedures exist." The departure procedures stated that "as soon as possible, but no later than crossing airport boundary, turn right to a heading of 360 degrees - a 30-degree right turn from runway heading - hold this heading for at least 2 miles from the airport. NOTE: It is recognized that aircraft performance will differ with aircraft type and takeoff conditions; therefore, the aircraft operator must have the latitude to determine whether takeoff thrust should be reduced prior to, during, or after flap retraction." According to local pilots, the normal procedure for departing Aspen and flying to the Denver area is to fly north, down the Roaring Fork River Valley, until the aircraft has enough altitude to reach the Ruedi Reservoir. A review of this route on the sectional aeronautical chart revealed that after takeoff, the pilot would have had to fly the airplane north-northwest approximately 8 to 10 nautical miles toward the town of Basalt prior to turning east toward the Ruedi Reservoir. The Woody Creek Valley branches off the Roaring Fork River Valley approximately 3 miles north of the airport. The Woody Creek Valley is surrounded by rapidly rising terrain on each side, and terminates at the Williams Mountains, which have a ridgeline with elevations between 12,000 and 12,700 feet msl. An NTSB database search for accidents occuring between 1983 and 1999 in the vicinity of the Aspen airport revealed that there were 8 accidents, 4 of which involved fatalities, in the accident site area that cited the high mountains and aircraft performance exceeded as causal and/or contributing factors. AIRCRAFT INFORMATION The 1949 model 4-seat airplane (serial number 7299) was equipped with a 300-horsepower Jacobs R755-A2 radial engine (serial number 31056). The aircraft maintenance records were not located during the investigation; however, an invoice and accompanying periodic aircraft inspection report indicated that the airplane underwent its last annual inspection on June 22, 2000, at a tachometer time of 4,282.0 hours. A calculation of weight and balance was conducted using estimated fuel and passenger weights. The estimated weight and balance was within the manufacturer's limitations. METEOROLOGICAL INFORMATION At 1053, the Aspen weather observation facility reported the wind from 330 degrees at 6 knots, visibility 10 statute miles, scattered clouds at 6,000 feet and broken clouds at 15,000 feet, temperature 23 degrees Celsius, dew point 4 degrees Celsius, and an altimeter setting of 30.01 inches of mercury. The density altitude was calculated by an NTSB investigator to be 10,518 feet. WRECKAGE AND IMPACT INFORMATION The accident site was located at 9,860 feet msl at a latitude and longitude of 39 degrees 14 minutes and 24 seconds North and 106 degrees 42 minutes and 42 seconds West. The wreckage distribution path, including an area of broken and cut trees, was oriented along a measured magnetic heading of 257 degrees (almost opposite the direction of flight depicted on the radar track) and measured approximately 130 feet in length. A fire consumed the cockpit/cabin area. The empennage remained partially attached to the fuselage and sustained impact damage. The vertical stabilizer and rudder, and the left horizontal stabilizer and elevator remained attached to the empennage. The right horizontal stabilizer was found separated from the empennage, but came to rest next to the empennage. The outboard portions of the wings were separated from the airplane and displayed leading edge damage. The right wing came to rest under freshly broken trees. The wings' fracture surfaces displayed characteristics consistent with overload failure. Flight control continuity was confirmed from the rudder and left elevator to the cabin area; however, due to the wing damage, confirmation of aileron control continuity was not possible. The engine sustained fire damage and remained attached to the airplane via control cables, and the propeller remained attached to the engine. Three cylinders were found separated from the crankcase and one was partially melted. Both propeller blades displayed chordwise scoring and fresh cuts were found in some of the fallen tree branches. The engine was relocated to a salvage facility where the spark plugs were removed and examined. The spark plugs appeared new and did not display any unusual wear or combustion properties. The engine's accessory section sustained impact and/or fire damage. MEDICAL AND PATHOLOGICAL INFORMATION An autopsy was not conducted on the pilot. A toxicological test on the pilot for carbon monoxide, cyanide, ethanol, and drugs was performed at the FAA's Civil Aeromedical Institute, Oklahoma City, Oklahoma. The results were negative. ADDITIONAL INFORMATION The wreckage was released to the owner's representative on February 11, 2002.
the pilot's poor in-flight decision to fly up a valley with rapidly rising terrain, which resulted in the airplane colliding with the terrain due to its climb performance being exceeded. A contributing factors was the high, rapidly rising, mountainous terrain.
