Contributing factors were the pilot's improper preflight and in-flight planning, snow and reduced visibility. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - In flight encounter with weather, cruise - preflight planning/preparation - improper, pilot in command (contributing factor) - weather condition - snow (contributing factor) - weather condition - other (contributing factor) - vfr flight into imc - continued, pilot in command (cause) - in-flight planning/decision - improper, pilot in command (contributing factor) - In flight collision with terrain/water, cruise - clearance - not maintained, pilot in command (cause) - terrain condition - snow covered ## Analysis During the night visual flight rules (VFR) cross-country flight, the airplane encountered instrument meteorological conditions (IMC) and impacted snow-covered terrain in a wings level attitude. Prior to the flight, the non-instrument rated private pilot did not obtain a weather briefing. According to data recovered from the airplane's portable global positioning system (GPS) receiver, the airplane departed the airport and initially traveled in a southwest direction toward the destination airport. Approximately 5 miles southwest of the departure airport, the airplane executed a left turn to the southeast. The airplane continued in a southeast direction for approximately 1 mile, then made a right turn back to the southwest. Shortly thereafter, the airplane then executed a 180-degree left turn to the northeast back toward the departure airport. Approximately 1 mile south of the departure airport, the airplane made a right turn to the south. The airplane continued south along a state highway for approximately 10 miles, then made a right turn toward the southwest. The airplane then headed in a southwesterly direction and the altitude varied between 6,800 and 7,300 feet mean sea level (msl). The last 15 recorded GPS positions indicated the airplane continued in a west-southwesterly direction; however, the altitude gradually decreased. The last recorded GPS position was located near the initial impact point with terrain. Local authorities reported the weather in the area at the time of the accident included snow, high winds, and reduced visibility. No communications were received from the airplane by any air traffic control facilities during the accident flight. According to a member of the pilot's family, the pilot had been "flying around Wyoming since the early 1980's." No anomalies were noted with the airframe and engine. ## Factual narrative HISTORY OF FLIGHT On January 17, 2007, at 1944 mountain standard time, a Cessna 182R, N9937H, piloted by a non-instrument rated private pilot, was destroyed when it impacted terrain during cruise flight near Waltman, Wyoming. The pilot and passenger were fatally injured. The airplane was registered to American Industrial Laundry, Inc., Lander, Wyoming, and operated by the pilot. Night instrument meteorological conditions prevailed, and a flight plan was not filed for the Title 14 Code of Federal Regulations Part 91 personal flight. The cross-country flight originated from the Gillette-Campbell County Airport (GCC) Gillette, Wyoming, at 1819, and was en route to Hunt Field Airport (LND), Lander, Wyoming. According to a member of the pilot's family, the pilot departed Lander en route to Gillette earlier on the day of the accident. The purpose of the flight was to pick up the passenger at Gillette and return to Lander. The airplane was equipped with a portable Garmin GPSMAP 396 global positioning system (GPS) receiver. A specialist with the NTSB's Vehicle Recorder Division extracted the data stored in the receiver. A review of the data indicated that the first leg of the flight departed from LND at 1635 and landed at GCC at 1758. Prior to departure from GCC, the airplane was refueled by a local fixed based operator (FBO) with 36.9 gallons of 100 low lead aviation fuel. The GPS data indicated that the accident flight departed GCC at 1819. A Google Earth overlay of GPS track log data indicated that the airplane departed GCC to the north and turned left to a southwest heading. Approximately 5 miles southwest of GCC, the airplane executed a left turn to the southeast. The airplane continued in a southeast direction for approximately 1 mile, then made a right turn back to the southwest. Shortly thereafter, the airplane then executed a 180-degree left turn to the northeast back toward GCC. Approximately 1 mile south of GCC, the airplane made a right turn to the south. The airplane continued south along state highway 59 for approximately 10 miles, then made a right turn toward the southwest. From 1922 to 1941, the airplane was headed in a southwesterly direction and the altitude varied between 6,800 and 7,300 feet mean sea level (msl). The following are the last 15 recorded GPS positions: Time Altitude Ground Speed Heading (feet msl) (miles per hour) (degrees True) 1942:08 7,016 140 266 1942:18 6,966 142 260 1942:29 6,942 143 259 1942:40 6,892 144 265 1942:49 6,830 146 264 1943:00 6,794 146 267 1943:14 6,729 146 262 1943:21 6,718 144 260 1943:34 6,685 144 266 1943:42 6,657 140 274 1943:49 6,707 135 266 1943:55 6,740 137 255 1944:00 6,684 147 251 1944:06 6,524 154 260 1944:10 6,455 Not Available Not Available The last recorded GPS position was at 1944:10, at 42 degrees 59.978 minutes north latitude and 107 degrees 24.867 minutes west longitude. No communications were received from the airplane by any air traffic control facility during the accident flight. On January 18, 2007, at 0837, an Alert Notice (ALNOT) was issued by Casper Flight Service Station for the accident airplane. According to local authorities, at 1131, Civil Air Patrol (CAP) reported they had located a downed aircraft near Waltman, Wyoming. A ground search was initiated by local authorities, and at 1147, the accident airplane was located approximately 40 miles east of Riverton, Wyoming, near Waltman. PERSONNEL INFORMATION The pilot, age 56, held a private pilot certificate with an airplane single-engine land rating. The pilot was issued a third-class medical certificate on August 31, 2005, with the limitation, "Must Wear Corrective Lenses." A review of the pilot's insurance records, dated November 9, 2006, indicated the pilot had accumulated 2,950 total flight hours, 2,900 hours in the accident airplane make and model, and 150 hours within the preceding 12 months. The pilot's most recent flight review was conducted on May 10, 2005. According to a member of the pilot's family, the pilot had been "flying around Wyoming since the early 1980's." The pilot was very familiar with the Lander to Gillette route of flight. AIRCRAFT INFORMATION The 1981-model Cessna 182R, serial number 18268126, was a single-engine, high wing, fixed tri-cycle landing gear, semi-monocoque design airplane. The airplane was powered by a normally aspirated, direct drive, air-cooled, horizontally opposed, carburetor equipped, six-cylinder Teledyne Continental Motors O-470-U engine (serial number 286595-R), rated at 230 horsepower, and equipped with a two-blade constant speed propeller. The airplane was configured to carry a maximum of four occupants. The airplane was issued a standard airworthiness certificate on December 9, 1981, and was certificated for normal category operations. The airplane was registered to the owner on May 5, 1983. A review of the airframe logbook revealed the most recent annual inspection was performed on November 6, 2006, at a total airframe time of 2,094 hours. The engine underwent it's most recent 100-hour inspection on November 6, 2006, at a total time 1,136 hours since major overhaul. At the time of the accident, the airframe had accumulated a total time of 2,116 hours. METEOROLOGICAL INFORMATION Prior to the LND to GCC flight and the accident flight, the pilot did not obtain a weather briefing from a flight service station or Direct User Access Terminal System (DUATS).
