Analysis

HISTORY OF FLIGHT

On September 29, 2008, at 2216:27 mountain daylight time, a Pilatus PC-12/47E, N606SL, owned and operated by a private pilot, was destroyed when it impacted terrain three nautical miles north of the Santa Fe Municipal Airport (SAF), Santa Fe, New Mexico. A post impact fire ensued. Dark night visual meteorological conditions prevailed at the time of the accident. The personal flight was being conducted under the provisions of Title 14 Code of Federal Regulations Part 91 on an instrument flight rules (IFR) flight plan. The private pilot, the sole occupant on board, was fatally injured. The cross country flight departed Lubbock Preston Smith International Airport (LBB), Lubbock, Texas, approximately 2115 and was en route to SAF.

The pilot's family reported that several days prior to the accident, the pilot had flown the accident airplane to Akron, Ohio, from his home near Santa Fe, to spend the weekend in Akron with friends. On the morning of the accident, the pilot left his hotel at an unknown time and proceeded to the Akron-Canton Regional Airport. According to Federal Aviation Administration (FAA) records, the pilot departed Akron-Canton Regional Airport, Akron, Ohio, at 0717 (0917 Eastern Daylight Time (edt))en route to Teterboro Airport (TEB), Teterboro, New Jersey. He arrived at TEB approximately 0850 (1050 edt). At Teterboro, the pilot contacted Lockheed Martin Flight Service Station (FSS) at 1353 (1553 edt) to file an IFR flight plan. The flight plan filed by the pilot identified TEB as the departure airport and SAF as the destination. The pilot planned six hours en route at flight level (FL) 280. The airplane departed TEB at 1424 (1624 edt). While en route, the pilot diverted to LBB to obtain fuel.

The pilot arrived at LBB at 2021 (2221 edt) and had the airplane refueled. He also spoke with his wife on the telephone, and did not report any problems regarding the airplane or himself. The pilot then departed LBB approximately 2115 (2315 edt).

Approaching Santa Fe, the pilot initiated a descent to 12,000 feet mean sea level (msl) as cleared by Albuquerque Center at 2158:56. The pilot was cleared for the visual approach into SAF at 2212:43 and canceled his flight plan ten seconds later. No further communications with the pilot were recorded.

Radar data, provided by Albuquerque Air Route Traffic Control Center (ZAB) in National Track Analysis Program (NTAP) format, depicted the accident flight approaching SAF. The airplane track progressed from the southeast towards the northwest on a measured magnetic bearing of 290 degrees in a descent. At an approximate altitude of 8,000 feet msl, approximately two nautical miles (nm) northeast of the airport, the track shifted to a magnetic bearing of 320 degrees and continued in a descent. The last radar target was recorded at 2216:27 at an encoded altitude of 7,200 feet msl, 3.2 nautical miles north of the airport on a measured magnetic bearing of 003 degrees from the airport. The airplane's ground speed remained above 200 knots until just prior to impact, when the ground speed slowed to 190 knots.

The National Transportation Safety Board (Safety Board) Investigator in Charge (IIC) interviewed one witness and received written statements from the same witness and one additional witness. The witnesses were located at SAF three miles south of the impact location. According to the witnesses, the airplane approached the airport from the "southeast" and "overflew" the area on a ground track consistent with a traffic pattern for one of the runways. The airplane was visible due to the airplane position lights. The pilot reported over UNICOM that he was five miles from the airport. The runway lights were activated and the level of lighting was adjusted several times following the radio transmission. No other radio calls were made by the pilot. There were no other aircraft in the area at the time of the accident. According to one witness, the airplane initiated a left turn towards the airport at which time the airplane pitched down and descended at a "steep angle." The two witnesses resumed their normal duties, waiting for the airplane to land, unaware that the airplane had crashed. According to one witness, it was standard practice for the pilot to report five miles out in addition to his position on downwind, base, and final for the landing runways. The pilot did not make any of these traffic pattern reports.

PERSONNEL INFORMATION

The pilot, age 54, held a private pilot certificate with airplane single engine land, multi-engine land, and instrument ratings last issued on April 11, 2006. He was issued a third class airman medical certificate on July 27, 2007. The certificate contained the limitation "holder shall wear lenses that correct for distant vision and possess glasses that correct for near vision."

The pilot's family provided the Safety Board IIC a digital copy of the digital logbook that the pilot had maintained on his personal computer. A review of these records revealed the pilot had logged no less than 2,437 hours total flight time; 1,456 hours in turbine aircraft, 86.5 hours in the Pilatus PC-12/47E, 14 hours in a Pilatus simulator, and 85 hours of night flight experience, 2.4 hours of which were in the Pilatus. The last flight in this digital record was logged on September 26, 2008, and the flight totals did not include his flight activity between that time and the accident flight. The pilot satisfactorily completed the Pilatus PC-12 NG initial course at SIMCOM Training Center on July 24, 2008.

AIRCRAFT INFORMATION

The accident airplane, a Pilatus PC-12/47E (serial number 1020), was manufactured in 2008. It was registered with the FAA on a standard airworthiness certificate for normal operations. The airplane was powered by a Pratt & Whitney Canada PT6A-67P turbo propeller engine rated at 1,200 shaft horsepower. The engine was equipped with a four-blade, Hartzell propeller (model number HC-E4A-3D, serial number KX596).

The airplane was registered to Gardner Leasing LLC, operated by the pilot, and was maintained under an annual inspection program. The airplane was new and had been registered on August 26, 2008. According to Safety Board estimates the airplane had flown 100 hours, between the time it was sold to the pilot and the accident, and had an estimated total airframe time of 130 hours. A review of the maintenance records revealed no maintenance had been performed since the sale of the airplane. The last maintenance performed was the installation of a cabin entertainment system. This maintenance was performed by Pilatus Business Aircraft in Broomfield, Colorado. The installation was completed on July 24, 2008, at an airframe total time of 27.6 hours.

The airport had three open runways at the time of the accident; runway 2/20 (8,342 feet by 150 feet, asphalt), runway 15/33 (6,307 feet by 100 feet, asphalt), and runway 10/28 (6,300 feet by 75 feet, asphalt). The control tower is open between the hours of 0700 and 2100. When the control tower is closed, the airspace reverts to Class E airspace.

WRECKAGE AND IMPACT INFORMATION

The accident site was located in rolling, sparsely vegetated terrain at an elevation of 6,347 feet msl. The initial impact point, as identified by the investigator in charge, was 3.2 miles north of the center point of the airport on a magnetic bearing of 352 degrees from the airport; just east of the extended centerline for runway 15 or 3,000 feet west of the last known radar position. The point consisted of a long narrow scar, measuring 23 feet in length, which extended to the initiation of the burn area. The scar was two feet at its widest point and blue paint chips consistent with a wing tip were located within the scar. Several ground scars followed the initial ground scar. A larger ground scar extended through the center of the burn area and measured ten feet in width and 70 feet in length.

The debris field extended from the initial impact point, 540 feet to the main wreckage on a bearing of 200 degrees. A large burn area was contained within the debris field. Components located within the debris path included the left landing gear assembly, torn metal and composite material, the fuselage door, three propeller blades, fragmented portions of the left wing, and aileron control rods from the right and left ailerons. Additional debris extended from the burn area to the main wreckage. Cabin components, charts, manuals, engine components, and various personal effects were located within this portion of the debris path.

The winglet from the left wing separated and was located at the north end of the burn area. The winglet exhibited lateral forward to aft scratching and scrape marks. The orientation of these scratch marks was consistent with a 46 degree bank angle to the left at impact. A portion of the left wing, measuring 55 inches in length, was located in the de...
