N3712F

HISTORY OF FLIGHTOn February 25, 2017, about 2040 mountain standard time, a Cessna 172H, N3712F, was substantially damaged during impact with terrain while maneuvering at a low altitude about 11 nautical miles (nm) north-northwest of Panguitch, Utah. The private pilot and two passengers were fatally injured. The airplane was registered to a private individual and operated by the pilot under the provisions of Title 14 Code of Federal Regulations Part 91. Dark night instrument meteorological conditions prevailed at the time of the accident, and no flight plan was filed for the personal cross-country flight that was being conducted under visual flight rules. The flight departed Page Municipal Airport (PGA), Page, Arizona, about 1930, with a destination of South Valley Regional Airport (U42), Salt Lake City, Utah.

According to a pilot-rated friend of the family, who resided in the same community as the accident pilot, reported that the pilot initially departed Phoenix-Mesa Gateway Airport (IWA), Phoenix, Arizona, during the late afternoon on the day of the accident. At 1849, he texted the pilot and asked him how the flight back was going. The pilot replied at 1852, and advised him that he had just landed at PGA and was in the process of getting fuel, to which the friend asked how the weather was? At 1854, the pilot responded that it was ok, cloudy, followed by asking his friend how the weather was at his destination. The friend replied, "Cloudy. You good in the dark with the clouds?" There was no immediate response from the pilot. At 1903, the friend asked the pilot if he was going to Kanab then Beaver, then up [Interstate Highway] I-15 for more city lights to follow?' Eight minutes later at 1911, the pilot replied, "I'm thinking of Bryce Canyon, then Richfield, then I-15 on up. How low are the clouds?" About 2 minutes later the friend informed the pilot, "To the east of my house they are all low. Low by the base of the mountain, but out to the west they are higher." Again, there was no immediate response from the pilot. About 8 minutes later at 1921, the friend queried the pilot by asking, "What does the AWC weather briefing say?" The pilot did not respond. At 1923, the friend informed the pilot, "My radar app shows weather over Tropic, but light and some over by Beaver. Nothing bad." At 1924, the pilot replied, "That's what I'm seeing too. I'm just going to stay over the highways." Eight minutes later at 1932, the friend commented, "That's what I like. Follow the light[s]. Keep me posted." The pilot did not respond. At 1940, after another 8 minutes had elapsed, the friend asked the pilot how it was going, to which there was no response; the last communication the pilot's friend received from that pilot was at 1924.

In a statement provided to the National Transportation Safety Board (NTSB) investigator-in-charge (IIC), a PGA fixed-based operator line foreman reported that, at 1850, the pilot called and requested after-hours fuel. The line foreman stated that he arrived at 1900 and topped off both fuel tanks with 18.3 gallons of 100LL aviation fuel. The foreman further stated that, after he had completed the fueling, he noticed that the pilot looked very tired. The foreman asked the two passengers if they wanted to lie down for a while. However, they declined and said that they wanted to get home. The foreman told the pilot that there was a place where they could lie down, but the pilot declined the offer. The pilot then loaded the airplane and left the FBO at 1918.

A review of recorded radar data identified the airplane at 1939:30 about 2.3 nm northwest of PGA, proceeding on a northwest heading at 5,400 ft mean sea level (msl). The flight continued to proceed northwest and climbed to an en route cruise altitude between 9,100 ft msl and 9,900 ft msl. The last radar return occurred at 2038:38, about 80 nm northwest of PGA, 160 nm south of U42, and about 2.85 nm southeast of the accident site at an altitude of 9,600 ft msl. The airplane subsequently impacted mountainous terrain in dark night conditions.

When the pilot failed to arrive at U42 that evening, a family member contacted local authorities. The Federal Aviation Administration (FAA) subsequently issued an alert notification at 0509 on February 26. Search and rescue operations began but were suspended later in the day with no sightings of the wreckage reported. About 1100 on February 27, search and rescue operations located the wreckage. PERSONNEL INFORMATIONThe pilot held a private pilot certificate with a single-engine land airplane rating. The pilot did not hold an instrument rating. He was issued a third-class FAA medical certificate, which was issued on September 18, 2015, with no limitations.

A review of the pilot's logbook revealed that he had accumulated a total of 176.9 hours of flight time as of December 29, 2016, which was the date of the last logbook entry. Additionally, the pilot had logged 113 hours as pilot-in-command, 65.3 hours of cross-country flight time, 10.5 hours of night flight time, and 120 hours of flight in the same make and model as the accident airplane. Additionally, the pilot's logbook revealed that he had flown about 6 hours within the preceding 90 days, with no time recorded in the last 30 days. AIRCRAFT INFORMATIONThe airplane was a four-place, high-wing, single-engine, 1966 Cessna 172H, serial number 17255207. It was powered by a 145-horsepower Continental O-300-D six-cylinder reciprocating engine, serial number 34931-D-6-D, and equipped with a two-bladed McCauley constant-speed propeller.

Maintenance records indicated that the most recent annual inspection was completed on April 14, 2016, at a recorded tachometer time of 7,239.75 hours, a recorded engine total time of 6,678.87 hours, and 1,577.14 hours since its last major overhaul. The last maintenance entry was dated October 8, 2016, at a tachometer time of 7,334.27 hours. The entry indicated that a new oil sump gasket was installed after troubleshooting an oil leak. The tachometer indicated 7,372.64 hours at the time of the accident. METEOROLOGICAL INFORMATIONThe National Weather Service (NWS) Surface Analysis Chart for 2000 on February 25, 2017, depicted a stationary front located across central Arizona with a high-pressure system over northern Utah. The accident site was located north of the front in an area with a weak pressure gradient. The surrounding station models over Utah indicated light north and west winds with variable cloud conditions from overcast to clear skies, and one station to the northwest of the accident site reporting light continuous snow.

Weather surveillance radar revealed an area of snow showers over the accident site, and an infrared satellite image depicted a band of low stratiform clouds over the accident site with tops near 14,000 ft msl. The cloud bases were estimated at 8,700 ft msl.

A NWS composite radar image for 2040 depicted several clusters of very light intensity echoes over southern Utah, which were consistent with snow showers. An area of echoes of very light intensity was located immediately east of the accident site and north of the departure airport. The presence of the echoes was consistent with an area of clouds and restricted visibility along the route of flight and potential localized mountain obscuration conditions.

The NWS's Center Weather Service Unit at the Salt Lake City air traffic control center (ZLC) issued a meteorological impact statement at 1136 that was valid until 2100. The statement was applicable to the accident area and indicated widespread marginal visual flight rules/instrument flight rules conditions in snow with low ceilings and visibility, and gusty surface winds in the northern ZLC area. These conditions were forecast to spread south and east through the afternoon and into Sunday night.

The Panguitch Municipal Airport (U55) was located about 12 nm south-southeast of the accident site at an elevation of 6,763 ft msl and had an automated weather observation system (AWOS) that broadcast weather locally. The observation issued immediately after the accident was as follows:

Panguitch weather at 2059, automated, wind from 040° at 3 knots (kts), visibility 10 statute miles, few clouds at 3,900 ft above ground level (agl), overcast ceiling at 4,800 ft agl, temperature -3°C, dew point -6°C, and altimeter 29.99 inches of mercury.

At 2053, the weather reporting station at the Bryce Canyon Airport (BCE), Bryce Canyon, Utah, located about 28 nm southeast of the accident site at an elevation of 7,590 ft msl, reported wind 250° at 5 kts, visibility 10 statute miles, sky clear, temperature -7°C, dew point -6°C, and altimeter 29.87 inches of mercury.

At 2040, the weather reporting station at the Milford Municipal Airport (MLF), Milford, Utah, located about 40 nm north-northwest of the accident site at an elevation of 5,042 ft msl, reported wind 350° at 10 kts, visibility 9 statute miles, light snow showers, few clouds at 2,200 ft agl, overcast clouds at 4,000 ft agl, temperature -2°C, dew point -4°C, and altimeter 29.95 inches of mercury.

Astronomical data from the United States Naval Observatory for Panguitch on February 25 indicated that sunset was at 1821, and the end of civil twilight was at 1847. Moonrise was at 0711, and moonset was at 1842. At the time of the accident at 2049, both the sun and moon were more than 15° below the horizon and provided no illumination.

The investigation found no evidence that the pilot had received a weather briefing before departing from PGA for the flight to U42.
