Accident Details
Probable Cause and Findings
the pilot's improper inflight planning/decision, and his failure to maintain terrain clearance while attempting a low altitude maneuver. Contributing factors were the mountainous terrain, the airplane’s low altitude, and the pilot's lack of total instrument time.

HISTORY OF FLIGHT
On October 1, 2002, approximately 1700 mountain daylight time, a Cessna T210M, N210HC, registered to and operated by W I Leasing of Englewood, Colorado, was destroyed when it impacted terrain while maneuvering 16 miles northeast of Laramie, Wyoming. The instrument rated private pilot, the sole occupant aboard, was fatally injured. Although visual meteorological conditions were reported in Laramie, evidence indicates instrument meteorological conditions existed at the accident site. An IFR flight plan had been filed for the business flight being conducted under Title 14 CFR Part 91. The flight originated at Twin Bridges, Montana, at 1335.
According to Federal Aviation Administration (FAA) documents, the pilot contacted the Great Falls, Montana, Automated Flight Service Station (AFSS) on his cellular telephone at 1115, and obtained a preflight weather briefing "to Denver Centennial or…in the Denver area somewhere down there." The pilot said he could go IFR but preferred VFR, because "[I] don't like it over the mountains that much." His preferred route was from "Sheridan straight to Laramie then down to Front Range. After some initial confusion as to where he was departing (Sheridan, Montana, not Sheridan, Wyoming), the pilot was advised of an AIRMET (airman meteorology) for "mountain obscurement and potential for icing."
The controller said, "I would certainly expect mountain obscurement. To go VFR underneath, you'd have to be fairly low, so it would be a little bit of a scud running situation. Can't recommend VFR into the mountains." The pilot replied, "It doesn't really sound like too good a trip to me," and the controller said, "No. At best, it'd be scud running. At worst, it would be IFR." Towards the end of the briefing, the controller added, "[You're looking at] mainly mountain obscurement and some spotty IFR through western and southwestern Wyoming. So, again, out over the plains, say, to Billings, and cut down the east sides of the Big Horns, you'll be in pretty good shape. If you stay VFR, in you want to stay VFR, you'll have to be fairly low altitude, but looks like there's enough room." The briefing terminated at 1127.
According to the pilot's wife, her husband departed Twin Bridges airstrip, near Dillon, and was en route to Erie, Colorado, on business. At 1412, the pilot contacted the Salt Lake Air Route Traffic Control Center (ARTCC), reported his position as being 22 miles southwest of Livingston, Montana, and requested an IFR clearance to Erie. The controller asked the pilot if he had a current flight plan on file, and what were his flight conditions. The pilot replied that he was not operating under a current flight plan, that he was not yet clear of clouds and had not encountered icing, and was receiving navigational signals from the Billing VOR. The controller told the pilot to contact Great Falls AFSS and file a flight plan, then report back to him.
At 1419, he contacted Great Falls AFSS, advised that he was in contact with the Salt Lake ARTCC, that he had been flying VFR "but had to cancel out," and wanted to air file an IFR flight plan. The pilot said he had departed Twin Bridges, Montana, at 1335, and his route of flight "from approximately Livingston" would be "direct Billings, direct Laramie, direct 48V (Erie, Colorado)." He said he had 4 hours, 15 minutes of fuel on board, and his estimated time en route was "another two hours." At 1423, the pilot reestablished contact with Salt Lake ARTCC. At 1527, the flight was handed off to the Denver ARTCC.
Recorded NTAP (National Track Analysis Program) radar data was retrieved by the Denver ARTCC and plotted. Data began at 1609:44 and terminated at 1625:52. In addition, FAA provided a transcript of voice communications, beginning at 1527:46 and terminating at 1620:43. According to this data, at 1527, the pilot contacted Denver ARTCC and reported to be level at FL190 (19,000 feet). He was given a heading change "for traffic" at 1550:45. At 1553:30 and again at 1554:44, the pilot requested a "turn back on course and if you could work out a lower altitude, we'd appreciate it." At 1555:23, the pilot was "cleared direct Laramie," and at 1555:58, he was cleared to "descend and maintain one seven thousand (feet)." He was also given the Casper, Wyoming, altimeter setting of 30.09.
At 1600:56, the controller advised all aircraft on his frequency of "convective SIGMET (significant meteorology) Four Whiskey (the transcript inadvertently said Four Two Charlie), …for portions of Wyoming, Utah and Arizona, also valid until two three five five Zulu (1755)," and to contact Flight Watch or Flight Service (Station) for details.
At 1611:20, the pilot of N210HC asked the controller if he could "work us out of one seven thousand (feet), down to one three thousand (feet) or one one thousand (feet)." The controller cleared the pilot to descend to 13,000 feet. The pilot acknowledged the clearance and remarked, "see if we can work our way through these clouds." Radar data showed the airplane already at 16,800 feet, and it began its descent at 1612:08.
At 1619:22, the pilot attempted to contact the controller but radio communications were unreadable, and the controller told the pilot to contact him on frequency 132.1 MHz. When the pilot did so, he said, "Yes, sir, I'm presently about thirty nine miles to the northwest of Laramie. Got a pretty big opening there. I ought to cancel out on this IFR. I think I can make a big circle and get under this scattered layer, if that's okay with you." At that point, radar data showed the airplane at 12,900 feet and descending. The controller approved the pilot's request to cancel his IFR flight plan and the pilot said, "We're showing thirty eight point eight (miles) to the northwest of Laramie." The controller confirmed the location. This was the last known radio transmission with the pilot.
According to the NTAP data, the transponder code was switched from 6042 to 1200 (VFR) at 1620:45 when the airplane was at 12,900 feet. Between 1620:26 and 1621:33, the airplane started a right turn and descended to 12,600 feet. Between 1621:33 and 1622:40, the airplane entered a left turn and descended from 12,600 feet to 12,100 feet. Between 1622:40 and 1623:28, the airplane started another right turn and descended from 12,100 feet to 11,900 feet. Between 1623:28 and 1625:52, the airplane made a 360-degree right turn, descending from 11,900 feet to 11,100 feet. At this point, radar returns became sporadic. At 1627:18, a radar return at 10,600 feet was detected to the north. At 1627:37, another radar return at 10,400 feet was detected. This was the last known radar contact with the airplane. These latter radar returns indicated the airplane was still in a right circling turn.
At 1817, satellites began picking up an ELT (emergency locator transmitter) signals from an area north-northeast of Laramie. Denver ARTCC issued an ALNOT (alert notice) at 2234. Ground search and rescue teams, working through the night, located the wreckage approximately 1100 the next morning at a location of 41 degrees, 25'24" north latitude, and 105 degrees, 29'48" west longitude, at an elevation of 8,461 feet.
The radar return at 1627:39 was at a position of 41 degrees, 51'35" north latitude, and 106 degrees, 07'31" west longitude and 10,500 feet. The first ground strike was at a location of 41 degrees, 25.772' north latitude, and 105 degrees, 28.518' west longitude, and 8,491 feet, a difference of 44.5 miles and 2,909 feet.
