Analysis
The pilot and passenger were searching for an overdue boat with the intent of landing at a remote unimproved airstrip located near the boat's intended destination. A witness reported strong wind conditions as she observed the airplane circle the airstrip. While the airplane was circling, its nose suddenly dropped, and the airplane descended in a near-vertical attitude to ground impact. She stated that the engine continued to run, and the airplane did not make any unusual sounds, other than an increase in engine rpm, during the descent.
A postaccident examination of the airframe and engine revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation. The observed damage to the airplane indicated that it impacted the ground in a nose-down, near-vertical attitude. The witness account and the damage to the airplane were consistent with the pilot failing to maintain sufficient airspeed while maneuvering, which resulted in the airplane's wing exceeding its critical angle of attack and a subsequent aerodynamic stall.
The airplane's estimated gross weight at the time of the accident was about 130.5 pounds over its approved maximum gross weight of 1,650 pounds, and the airplane's estimated center of gravity was about 0.1 inches beyond the approved aft limit at gross weight. As excessive weight increases stall speed and an aft center of gravity decreases controllability, it is likely that the pilot's decision to operate the airplane over gross weight with an aft center of gravity contributed to the loss of control.
Probable Cause and Findings
The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's failure to maintain adequate airspeed while maneuvering in high winds, which resulted in the airplane exceeding its critical angle of attack and an aerodynamic stall. Contributing to the accident was the pilot's improper decision to load the airplane beyond its allowable gross weight and center of gravity limits.

Factual Information
HISTORY OF FLIGHT
On May 27, 2017, about 1122 Alaska daylight time, an Arctic Aircraft Company S-1B2 airplane, N57AT, impacted terrain following a loss of control, about 35 miles east of Salcha, Alaska. The private pilot and the passenger sustained fatal injuries, and the airplane was substantially damaged. The airplane was registered to Brice Consulting LLC and operated by the pilot as a 14 Code of Federal Regulations Part 91 personal flight. Visual meteorological conditions prevailed, and no flight plan had been filed. The flight departed from an off-airport landing site near Fairbanks, Alaska, about 0925.
According to a family member of the pilot, the purpose of the flight was to search for an overdue boat that was piloted by a family member of the passenger with the intent of landing at a remote unimproved airstrip located near the boat's destination. The boat had left the previous evening for a recreational cabin located along the Salcha River.
During a telephone conversation with the National Transportation Safety Board (NTSB) investigator-in-charge (IIC) on June 1, 2017, a witness reported that she observed the airplane circle the remote unimproved airstrip along the Salcha River. While the airplane was circling, its nose suddenly dropped, and the airplane descended in a near-vertical attitude. She stated that the engine continued to run, and the airplane did not make any unusual sounds, other than an increase in engine rpm, during the descent. The witness reported strong wind conditions prevailed at the time of the accident.
PERSONNEL INFORMATION
The pilot, age 81, held a private pilot certificate with an airplane single-engine land rating. His most recent third-class medical was issued on September 30, 2015, with the limitation that he must wear corrective lenses.
Personal flight records were located for the pilot; however, they were not complete. The aeronautical experience listed in this report was obtained from a review of the Federal Aviation Administration (FAA) records for the pilot on file in the Airman and Medical Records Center located in Oklahoma City. The pilot did not report flight experience on his most current application for a medical certificate dated, September 3, 2015. However, on his application for a prior medical certificate, dated August 7, 2013, he indicated that his total aeronautical experience was about 1,960 hours of which 60 hours were in the previous 6 months.
AIRCRAFT INFORMATION
At the time of the accident, the 1978 model year airplane had a total time in service of 3,087.50 flight hours. A review of the maintenance records revealed that the most recent annual inspection of the airframe and engine was completed 27.10 flight hours before the accident on June 9, 2016.
The airplane was equipped with a 160-horsepower Lycoming O-320 B2B engine. At the time of the accident, the engine had accumulated 1,748.00 hours since overhaul.
METEOROLOGICAL INFORMATION
The closest official weather observation station to the accident site was Eielson Air Force Base, Fairbanks, Alaska, located about 35 miles east of the accident site. At 1058, Eielson was reporting, in part, wind calm; visibility 10 statute miles; clouds and ceiling 10,000 ft broken; temperature 52°F; dew point 27°F; and altimeter 30.04 inches of mercury.
WRECKAGE AND IMPACT INFORMATION
The wreckage was located in an area of black spruce trees and tundra-covered terrain at an elevation about 1,000 ft mean sea level. The on-scene examination revealed that the airplane impacted in a near-vertical attitude, and the nose of the airplane was on about a 110° magnetic heading.
All of the airplane's major components were found at the main wreckage site. The cockpit area was extensively damaged. The engine, firewall, and instrument panel were displaced upward and aft. The mixture control was found in the full-forward position, and the carburetor heat was in the off position.
The airplane's right wing remained attached to the fuselage. About 2 feet of the outboard portion of the right wing exhibited extensive leading edge aft crushing. The airplane's left wing separated from the fuselage at its rear attach point but remained attached at its forward attach point.
The left and right flaps remained attached to their respective attach points. The inboard portion of the right flap was crushed against the side of the fuselage and bent about 20° down. The left flap was relatively free of impact damage.
The horizontal and vertical stabilizer, elevators, and rudder remained attached to the empennage and were free of impact damage.
All the primary flight control surfaces were identified at the accident site, and flight control continuity was verified from the cockpit to the elevators and rudder. Aileron control continuity was established in the direct cables from the cockpit to the right aileron and from the cockpit through the point where the cable's turnbuckle was disassembled for recovery to the left aileron. In addition, aileron control continuity was established in the balance cable from the right and left ailerons to the point where the cable fractured with features consistent with tension overload.
The engine sustained impact damage to the front and underside. An examination of the engine did not reveal any anomalies, contamination, or evidence of malfunction in any of the engine accessories. Examination of the cylinders, pistons, valve train, crankshaft, and other internal components revealed no evidence of an anomaly or malfunction that would have precluded normal operation. Both magnetos were removed from the engine, and their couplings were rotated by hand. When each coupling was rotated, blue spark was observed at the distributor in rotational order.
The propeller remained attached to the engine crankshaft by 2 of the 6 attach bolts. One propeller blade exhibited substantial torsional "S" twisting and light chordwise scratching. The other propeller blade exhibited light chordwise scratching and aft bending about 3 inches from the tip.
The examination of the airframe and engine revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation.
MEDICAL AND PATHOLOGICAL INFORMATION
The Alaska State Medical Examiner, Anchorage, Alaska, conducted an autopsy of the pilot on May 30, 2017. The cause of death was attributed to multiple blunt force injuries.
The FAA's Bioaeronautical Sciences Research Laboratory, Oklahoma City, Oklahoma, performed toxicology testing on specimens from the pilot. The testing was negative for carbon monoxide and alcohol. The testing revealed unspecified levels of verapamil in the blood and liver and its active metabolite, norverapamil, in the blood. Verapamil is a prescription calcium channel blocker used to treat high blood pressure, angina, and arrhythmias.
TESTS AND RESEARCH
At the time of the accident, the pilot was using a Garmin Aera series portable global positioning system (GPS) receiver capable of storing route-of-flight data. The unit was sent to the NTSB's Alaska Regional Headquarters and data for the accident flight, which included, in part, time, latitude, longitude, and GPS altitude were extracted. Groundspeed and course information were derived from the extracted parameters.
The GPS data logs for May 27, 2017, revealed that the flight departed the remote off-airport landing site about 0925:30. After departure, the airplane proceeded southeast along the Tanana River before it turned east and proceeded up the Salcha River. The last fully recorded GPS data point was at 1122:39 when the airplane was at 1,705 ft (GPS derived altitude), heading 132° (true), and 47 knots ground speed.
A flight track map overlay and tabular data corresponding to the accident flight are available in the public docket for this accident.
ADDITIONAL INFORMATION
Estimated Weight and Balance
An estimate of the airplane's weight and balance at the time of the accident was calculated based on the following information.
The pilot's weight was taken from his most current FAA medical examination. The weight of the rear seat passenger was taken from his Alaska state driver's license.
In a telephone conversation with the NTSB IIC on July 26, 2017, the Alaska State Troopers who recovered two backpacks from the accident site estimated their total weight at 25 pounds, or about 12.5 pounds each.
During a conversation with the IIC, a family member of the pilot reported that fuel was not available at the remote landing site along the Salcha River. The fuel onboard at the time of the accident was estimated by calculating the amount of fuel required for the estimated 45-minute direct return flight from the accident site to the originating airstrip plus the required 30-minute reserve. Using an average fuel burn rate of 8 gallons per hour, the quantity of fuel in the airplane at the time of the accident was estimated to be 10 gallons.
A friend of the pilot provided the NTSB IIC with a list of items that were onboard the airplane at the time of the accident. Exemplar items were weighed, and those weights were used to compute the weight and balance.
The last documented weight and balance information located for the airplane was dated May 29, 2015. At that time, the basic empty weight of the airplane on wheels was 1,274.50 pounds with a center of gravity of 11.53 inches.
Basic Empty Weight– 1,274.50 pounds
Pilot– 184 pounds
Rear Seat Passenger – 170 pounds
24 pack water – 27 pounds
6 bottles wine – 17 pounds
Frying pan – 0.5 pounds
8 pack paper towels – 4 pounds
3 patio pillows – 3.5 pounds
2 backpacks – 25 pounds
Fuel (10 gallons) – 60 pounds
Oil (8 quarts) – 15 pounds
Using the values listed above, the gross weight of the airplane at the time of the accident was estimated to be 1,780.5 pounds, which was 130.5 pounds over the approved maximum takeoff gross weight for the airplane of 1,650 pounds. The estimated center of gravity at the time of the accident was 15.896 inches. The center of gravity range at 1,650 pounds (maximum gross weight) was 11.0 inches to 15.8 inches.

This is preliminary information, subject to change, and may contain errors. Any errors in this report will be corrected when the final report has been completed. NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.
On May 27, 2017, about 1100 Alaska daylight time, an Arctic Aircraft Company Incorporated, S-1B2 airplane, N57AT, sustained substantial damage following a loss of control and a subsequent impact with terrain, about 35 miles east of Salcha, Alaska. The airplane was registered to Brice Consulting LLC and operated by the pilot, as a visual flight rules (VFR) flight under the provisions of 14 Code of Federal Regulations (CFR) Part 91 when the accident occurred. The private pilot and sole passenger were fatally injured. Visual meteorological conditions prevailed, and no flight plan had been filed. The flight departed from an off-airport landing site near Fairbanks, Alaska about 1000.
According to a family member of the pilot, the purpose of the flight was to search for an overdue boat along the Salcha River.
During a telephone conversation with the National Transportation Safety Board (NTSB) investigator-in-charge (IIC) on June 1, a witness reported strong wind conditions. She observed the airplane circle a remote unimproved landing site along the Salcha River. While circling, the nose of the airplane suddenly dropped and the airplane descended in a near vertical attitude. She stated that the engine continued to run, and the airplane did not make any unusual sounds, other than an increase in engine RPM during the descent.
The NTSB IIC, along with an Alaska State Trooper reached the accident site in the evening of May 27. The airplane impacted in a near vertical attitude in an area of black spruce trees and tundra-covered terrain, at an elevation of about 1,000 feet mean sea level, on a heading of about 110 degrees. All the primary flight control surfaces were identified at the accident site, and flight control continuity was verified from the cockpit to the elevators and rudder. Aileron control continuity was established in the direct cables, from the cockpit to the right aileron, and from the cockpit to the point where the cable's turnbuckle was disassembled for recovery to the left aileron. In addition, aileron control continuity was established in the balance cable from the right aileron to the point where the cable fractured with features consistent with tension overload, to the left aileron. A detailed wreckage examination is pending following recovery of the airplane.

She stated that the engine continued to run, and the airplane did not make any unusual sounds, other than an increase in engine RPM during the descent.
The NTSB IIC, along with an Alaska State Trooper reached the accident site in the evening of May 27. The airplane impacted in a near vertical attitude in an area of black spruce trees and tundra-covered terrain, at an elevation of about 1,000 feet mean sea level, on a heading of about 110 degrees. All the primary flight control surfaces were identified at the accident site, and flight control continuity was verified from the cockpit to the elevators and rudder. Aileron control continuity was established in the direct cables, from the cockpit to the right aileron, and from the cockpit to the point where the cable's turnbuckle was disassembled for recovery to the left aileron. In addition, aileron control continuity was established in the balance cable from the right aileron to the point where the cable fractured with features consistent with tension overload, to the left aileron. A detailed wreckage examination is pending following recovery of the airplane.
The closest weather reporting facility is Eielson Air Force Base, Fairbanks, Alaska approximately 35 miles east of the accident site. At 1058, an aviation routine weather report (METAR) at Eielson Air Force Base, reported wind, calm; visibility, 10 statute miles, clouds and sky condition, broken clouds at 10,000 feet; temperature, 52° F; dew point, 27° F; altimeter, 30.04 inHG.

FAIRBANKS — People across Alaska are mourning two Interior Alaska businessmen who died Saturday in a small plane that went down near the Salcha River.
The cause of the crash remains under investigation, the chief of the National Transportation Safety Board’s Alaska office said.
Plans for memorial services for Sam Brice, 81, and Buzz Otis, 63, are pending. Condolences are flowing to the Brice and Otis families through calls, emails and social media.
“We lost two great Alaskans in that accident,” U.S. Rep. Don Young, R-Alaska, said in a phone interview Tuesday.
U.S. Sens. Lisa Murkowski, R-Alaska, and Dan Sullivan, R-Alaska, paid tribute to the men on Facebook.
“These two leaders knew what ‘North to the Future’ really meant and advanced that vision every day of their adult lives,” according to a tribute on Murkowski’s Facebook page. Sullivan called them “anchors of the Interior community.”
Sen. John Coghill, R-North Pole, recognized Otis and Brice during a special order given on the Senate floor Tuesday. He said the two had contributed much to their communities.
“Both wonderful men, key to many, many things in our community and they did live well,” he said. “They were significant givers, and builders and contributors to the community. They did live well.”
Both men were involved in starting construction companies, Great Northwest Inc. and Brice Inc., that have endured.
Otis also served on the Fairbanks North Star Borough Assembly in the 1980s.
Rep. Chris Birch, R-Anchorage, served with Otis and said he remembers him as a great family man, problem solver and conservative.
Otis was one of the leaders who oversaw the effort to build the Carlson Center. The project had to be scaled back because of a state budget crisis, Birch said.
“Buzz was always one for responsible government,” Birch said.
Bruce Wammack, who also served on the assembly at the time, agreed and added Otis was also fair-minded.
“Even though he had strong convictions himself, he always listened to the other side,” he said.
J.B. Carnahan, who also served with Otis on the assembly, said he remembers Otis showing up to meetings beaten and bruised from playing rugby, his hobby at the time.
“He was the kind of guy who was always upbeat, always a lot of fun and really community-minded,” Carnahan said.
Brice was well known in rural Alaska.
“He was really generous and treated everyone like family,” said Herbie Moses, of Allakaket, who has worked for Brice Inc. for 22 years.
Walton Smith, St. Mary’s city manager, said Brice was the kind of person who stood by his word.
“He represented to me a past era of handshake agreements, trust and making your word your bond,” he said in an email to the Brice family.
Smith said in an interview Brice Inc. did business with the city of St. Mary’s and Brice always did the job he said he would do.
“He had kind of a raspy voice and a little bit of Southern accent left. I just felt very comfortable with him,” Smith said.
Donna Erick, of Venetie, worked with Brice on two Interior airport projects as a contract officer.
“He was a hard-working man all of his life,” she said. “He knew the work ethic, and he was good to people.”
Former Alaska Gov. Frank Murkowski, who also served in the U.S. Senate, said he knew Otis and Brice and they were “colorful characters.”
“It’s a significant loss,” he said in an interview from his cabin in Wrangell.
Multiple state legislators paid tribute to the men on social media as did Fairbanks city Mayor Jim Matherly.
Clint Johnson, of the NTSB, said an investigator flew to the crash site about 50 miles east of Fairbanks near Butte Creek at about 5 p.m. Saturday with Alaska State Troopers.
“At this point right now, they are in the recovery phase of trying to get the airplane out,” Johnson said.
The aircraft, an Arctic Tern, which is similar to a Super Cub, belonged to Brice.
“We are truly in the formative stages, the very preliminary stages of this investigation,” Johnson said. “We are working very closely with both families and also their insurance company to facilitate getting the wreckage out of the field.”
The Otis family is asking anyone who wants to share a story about Otis to email buzzotismemorial@gmail.com.
FAIRBANKS - Alaska State Troopers have released the names of two men killed in a plane crash near Salcha on Saturday.
The victims have been identified as: Sam R. Brice, 81, of Fairbanks and Howard A. "Buzz" Otis, 63, of North Pole.
The National Transportation Safety Board received word at 11 a.m. that a singe-engine Arctic Aircraft S-1B2 “Arctic Tern” had crashed near Butte Creek north of the Salcha River, NTSB Alaska Chief Clint Johnson said.
Otis was a former member of the Fairbanks North Star Borough Assembly, serving from 1982 to 1988 and at one point being chosen as the assembly’s presiding officer.
Otis was a leading community figure and booster in North Pole, where he was currently serving as executive director of the North Pole Economic Development Corp.
He founded Great Northwest Inc. in 1975 with partner John Minder. The company grew from its beginnings as a residential landscaping company to a large general contractor that, according to the company’s website, specializes in projects such as road and airport construction, underground utilities, erosion protection and riverbank restoration.
Otis later sold his share of Great Northwest.
He was also a former chairman of the Fairbanks Economic Development Corp.
Otis, as head of the North Pole Economic Development Corp., helped bring the International Federation of Sleddog Sports 2013 Winter World Championships to the city. The event, which features the world’s top dog mushers and skijorers, is held every two years and alternates between North America and Europe.
Otis is also the lead organizer of the North Pole Championship Sled Dog Races and the Junior North American Championship Sled Dog Races.
Brice and his two brothers, Al and Andy, with their parents, founded a lumber company that grew into a Fairbanks-based land-clearing company, Brice Inc., that helped clear the right-of-way for the trans-Alaska oil pipeline.
The company expanded into remote civil construction and established its own land and water transportation and equipment fleet tailored to the needs of remote Alaska. They became Brice Inc., Brice Environmental, Brice Marine, Brice Equipment and Brown’s Hill Quarry. In 2010, Calista bought the Brice businesses, which are still run by a generation of the Brice family.
Word of the Arctic Aircraft crash occurred almost simultaneously with another crash, a twin-engine Piper PA30 that went down on a beach near Haines. Two other people died in that crash and a third was seriously injured.
Troopers received the report of a downed aircraft on Glacier Point 10 miles south of Haines. A witness observed the plane take off, make a hard right turn to the east and stalling before crashing.
The pilot, David Kunat, 29, of Juneau and an adult male passenger from California were both declared dead at the scene. Another passenger, Chan Valentine, 31, of Juneau survived the crash and was transported to Bartlett Regional Hospital for medical treatment. Kunat’s next of kin have been notified and attempts to locate next of kin on the passenger from California are continuing.
Alaska Wildlife Troopers responded in a vessel and multiple Temsco helicopters helped with rescue efforts. Authorities from the NTSB are responding for further on-scene investigation.
