Probable cause
The NTSB’s determination of the probable cause, and any contributing factors.
Pilot incapacitation for unknown reasons.
Analysis
At 1407:11 the flight was cleared from Flight Level (FL) 240 to descend and maintain FL 190. At 1409:08 the controller cleared the flight to descend and maintain 15,000 feet, and at 1409:17 the pilot read back the clearance in its entirety. At 1410:20 the controller instructed the pilot to expedite his descent through 16,000 feet for traffic; however, there was no response. From 1410:33 to 1417:21 the controller made ten attempts to contact the pilot; again, there was no response. At 1417:26 the controller requested the pilot to ident if he could still hear him. At 1417:38 the controller received an ident from the aircraft and instructed the pilot to descend and maintain 15,000 feet. At 1418:36 the controller cleared the aircraft for the GPS approach and to acknowledge with an ident. There was no response. The aircraft had impacted a rocky drainage trench near the base of rock outcropping on a magnetic heading of 200 degrees in a wings level, approximately 40-degree nose down attitude, 15 nautical miles east-southeast of the destination airport at an elevation of 5,630 feet mean sea level. An examination of the aircraft's flight control, pressurization, and electrical systems revealed no anomalies with these systems which would have precluded normal operations. A further examination of the thermal damage to the aircraft, determined that there was no evidence of an inflight fire. Both engines underwent a complete teardown examination revealing no evidence of catastrophic or preaccident failure, and that both engines were functioning at the time of impact. Radar data revealed the aircraft was in level flight at FL 190 for more than 4 minutes, when it had previously been cleared to 15,000 feet. It subsequently began a climb reaching an altitude of 20,300 feet before beginning a right descending turn followed by a left descending turn. The last radar return before radar contact was lost indicated the aircraft was at 15,900 feet and descending. No evidence was available that suggests icing greater than light rime icing was present in the area and that weather was unlikely to have been a factor in the accident. The pilot was on two medications for high blood pressure and one for high cholesterol. The pilot had recently been found to have an elevated blood sugar, suggesting early diabetes or some other systemic disease or injury. The pilot had a family history of heart disease and high blood pressure, and had at least one episode of chest tightness in the past. It is possible that he had some unrecognized heart disease. The circumstances of the accident suggest substantial impairment or incapacitation of the pilot. It is possible that the pilot experienced an event such as a stroke or heart attack related to his previous medical conditions or as a new occurrence. It is also possible that he became hypoxic as a result of a decompression event without using supplemental oxygen. There is insufficient information to conclude any specific cause for the pilot's impairment or incapacitation.

History of flight
On March 15, 2003, approximately 1425 mountain standard time, a Cessna 501, N70FJ, was destroyed when it impacted terrain following an uncontrolled descent near Carey, Idaho. The airplane was registered to Dancing Wind Aviation LLC, of Livingston, Montana, and operated by the pilot. The airline transport pilot and two passengers sustained fatal injuries. Instrument meteorological conditions prevailed and an instrument flight rules (IFR) flight plan was filed for the 14 CFR Part 91 personal cross-country flight. The flight originated from the Salt Lake International Airport (SLC), Salt Lake City, Utah, at 1340, and was destined for the Friedman Memorial Airport (SUN), Hailey, Idaho.
According to initial data from the Western Air Defense Sector, McCord Air Force Base, Tacoma, Washington, and the Salt Lake Air Route Traffic Control Center (SLC ARTCC), N70FJ departed flight level 350 for flight level 240 at 1359:57. At 1407:08 the pilot reported that he was at flight level 240, and at 1407:11 SLC ARTCC cleared the aircraft to descend and maintain flight level 190. At 1408:25 the pilot queried SLC ARTCC "if aircraft were missing the approach into Hailey?" At 1408:29 the controller told the pilot, "You can make it in on the RNAV (Area Navigation) approach sir. Are you able the RNAV?" The pilot replied, "That's affirmative." At 1408:37 the controller further advised the pilot, "The last one made it in on an RNAV just at the bare minimums and Hailey says it's getting worse there, so I got a couple stacked up right now. I'll get you lower and a holding pattern set up. I'll put you in a hold at Oreye if that's going to work for you sir. N70FJ, cleared direct Oreye. Expect holding at Oreye and expect the RNAV approach from there once I get the pattern clear sir." At 1409:07 N70FJ confirmed "direct Oreye for Fox Juliet." At 1409:09 the controller cleared the aircraft to 15,000 feet, which was followed by N70FJ confirming the clearance. At 1410:21 the controller instructed the pilot of N70FJ to expedite his descent to 16,000 feet for traffic. There was no response. From 1410:33 to 1417:21, SLC ARTCC made ten attempts to establish radio communications with N70FJ, all of which proved unsuccessful. At 1417:26 the controller requested N70FJ to "ident if you hear me." At 1417:39 the controller confirmed that she had received N70FJ's ident, that she had not received any replies to her previous attempts to contact the aircraft, and that if possible the pilot might try using another radio to establish communications with SLC ARTCC. The controller also instructed the pilot to descend and maintain 15,000 feet. At 1418:36 the controller cleared the aircraft direct to the Oreye intersection for the GPS (global positioning system) approach and to acknowledge with an ident. There was no further radio communication or radar contact with N70FJ. Post accident data provided by SLC ARTCC indicates center received the ident at 1417:35 reporting 19,700. The ident remained on for one (1) minute until 1418:35.
On March 15, 2003, at 1527, an alert notification (ALNOT) was issued for N70FJ. At approximately 0700 on March 16, 2003, the aircraft wreckage was located in an area of mountainous terrain bordered by a valley running east to west 10 nautical miles north of Carey, Idaho, and 15 nautical miles east-southeast of SUN. On March 18, 2003, the aircraft wreckage was recovered by personnel from Air Transport, Phoenix, Arizona.
Personnel
The pilot held an airline transport pilot certificate with a multiengine land rating and a Cessna 500 type rating, commercial privileges for single engine land and sea airplanes, and private privileges for helicopters. The pilot obtained his Cessna 500 type rating on April 12, 1986, and his most recent single pilot proficiency check for the Cessna 500 was satisfactorily completed on May 24, 2002. Records furnished by a family member indicated that the pilot had accumulated a total of 1,382 hours of total flying time in Cessna 500 series aircraft from March, 1985, through December, 1999.
According to Federal Aviation Administration (FAA) aeromedical records, dated April 11, 2002, the pilot reported having 14,000 total flying hours with 150 hours in the 6 months prior to the examination. The pilot held a second class medical certificate with the limitation "must wear corrective lenses".
Aircraft information
N70FJ, a Cessna 501 Citation (certified for single pilot operation), serial number 0073, was issued an airworthiness certificate on July 31, 1978. The airplane was configured to carry six passengers and two pilots, and was equipped with two Williams/Rolls FJ44-2A fanjet engines rated at 2,300 pounds of thrust per engine.
The Cessna Citation Operating Manual limitations for single pilot operations include in part: "1 boom microphone or headset mounted microphone." The operating manual states in part: "The pilot-in-command must have a C-500 Type Rating and meet the requirements of FAR 61.58 for two-pilot operation, or FAR 61.57 for single pilot operation (Model 501 only).
The aircraft was modified in accordance with numerous Supplemental Type Certificates (STCs) during the period of August 2002 through October 2002. These modifications included the Eagle SP recontoured wing leading edges, increased gross weight, increased fuel capacity, installation of the Williams/Rolls FJ44-2A engines, complete interior refurbishment, installation of Keith Products air conditioning system, aft baggage compartment, and numerous interior modifications. There were also numerous avionics installations and alterations to the aircraft, including Traffic Alert and Collision Avoidance System (TCAS), Enhanced Ground Proximity Warning System (EGPWS), Electronic Flight Information System (EFIS), Multi Function Display (MFD), and a Global Positioning System (GPS).
The last completed Aircraft Flight Log page includes flight information through March 10, 2003, which included an aircraft total time of 7118.0. The flight time for the final four flights between March 13th and March 15th were estimated by the Flying J, Inc., Aviation Department, based on their knowledge of the pilot's activity during this time period. The estimated total aircraft time at the time of the accident was 7120.2 hours, and the total time for each engine was 91.8 hours.
