Aircraft: CESSNA 208B
Aircraft Damage: Substantial
Defining Event: VFR encounter with IMC
Injuries: 1 Fatal
Flight Conducted Under: Part 135: Air Taxi & Commuter - Non-scheduled
On May 1, 2017, about 1350 Alaska daylight time, a Cessna 208B airplane, N803TH, sustained substantial damage after impacting steep, mountainous terrain near Chignik Lake, Alaska. The airline transport pilot was fatally injured. The airplane was operated by Grant Aviation, Inc., as a Title 14 Code of Federal Regulations (CFR) Part 135 non-scheduled mail contract flight. Instrument meteorological conditions (IMC) existed at the accident site and company flight following procedures were in effect for the visual flight rules flight, which departed Port Heiden Airport (PAPH), Port Heiden, Alaska, at 1325, destined for Perryville Airport (PAPE), Perryville, Alaska.
The pilot's flight and duty records indicated that he reported for duty about 0800 the morning of the accident. The pilot was scheduled for a six-segment route the day of the accident, originating from King Salmon Airport (PAKN), King Salmon, Alaska; the accident occurred on the second segment. The flight departed on the first segment at 1215 and proceeded to PAPH, arriving at 1313 with one passenger, who disembarked at PAPH. The passenger, who was a private pilot who often flew on Grant Aviation flights, reported that the pilot flew the segment lower than usual due to low clouds and that the pilot flew through clouds during the flight. The village agent who assisted the pilot on the ground stated that he appeared to be in good spirits. The airplane departed PAPH at 1325. The destination airport was about 80 miles south and located in a remote coastal area that did not have official weather reporting or instrument approaches available. The route required crossing the Aleutian Peninsula and mountainous terrain with elevations between 2,900 ft and 4,600 ft. The airplane's route of flight during this segment could not be determined as the area was not covered by radar service and the airplane was not equipped with tracking equipment.
At 1353, the Grant Aviation director of operations (DO) was notified that the US Coast Guard had received a 406-MHz emergency locator transmitter (ELT) signal from the accident airplane. The DO initiated the company's overdue aircraft procedures.
The wreckage was located at 1730 about 24 miles northeast of PAPE on a steep, snow-covered mountain. A rescue crewman was hoisted down to the site and determined that the pilot, who was inside the cockpit and strapped in his seat, had received fatal injuries. See figures 1 and 2.

At the time of the accident, an AIRMET valid for the accident site forecast mountain obscuration conditions due to clouds and precipitation. The area forecast issued at 1214 predicted scattered clouds at 2,000 ft above ground level (agl) and broken ceilings at 2,000 ft and 5,000 ft with tops to 10,000 ft. The ceiling was forecast to be occasionally at 2,000 ft with isolated light rain showers and a freezing level at 1,500 ft. No turbulence or icing conditions were forecast. The Alaska Aviation Weather Unit flying weather graphic valid during the accident flight indicated marginal visual flight rules (VFR) conditions for the route of flight.
The nearest official weather reporting station was Chignik Airport (PAJC), located about 18 miles northeast of the accident site. At 1239, an aviation special weather report reported variable wind at 4 knots; 10 statute miles visibility; light rain; overcast clouds at 1,700 ft; temperature 39°F, dewpoint 36°F; and an altimeter setting of 29.51 inches of mercury.
The visible and infrared data from the Geostationary Operational Environmental Satellite number 15 (GOES-15) at 1300 indicated an overcast layer with mountain obscuration likely and cloud tops at 9,000 ft.
FAA weather camera images from Chignik Lake, about 7 miles north-northeast of the accident site at an elevation of 45 ft, revealed ceilings between 900 ft mean sea level (msl) and 2,700 ft msl, with forward visibilities between 1.5 and 5 miles in the vicinity of the accident site around the accident time (see figure 3). The images further suggest that mountain obscuration conditions prevailed with likely rain shower activity.
Figure 3. South-facing Chignik Lake FAA weather camera image on a clear day (left) and before the accident at 1347 (right).The PAPE village agent stated that the weather at PAPE was generally good on the day of the accident. She was not a trained weather observer, but she had been observing weather in the area for over 10 years and knew how to estimate ceilings and visibility distances based on surrounding landmarks. She recalled that, while she was waiting on the airplane to arrive, the clouds were 3,000 ft scattered and visibility was 10 miles. She could see north over the pass to Chignik, which meant the ceiling was at least 2,500 ft in the mountain pass. She stated that the accident pilot did not call her for a weather observation update.
The dispatch agent on duty recorded airport weather information on a company form at intervals throughout the accident day. The PAPE weather entry, provided by the village agent at 1021, indicated winds from the east at 10 knots, 10 miles visibility, and an overcast ceiling of 3,500 ft. That was the sole entry for PAPE for the day, even though the flight was due to arrive at 1350. According to the dispatch agent's statement, she did not talk to the pilot or verbally provide any updates to him during the flight. The dispatch agent stated that she used the FAA Alaska weather camera website and village agent observations to document the weather for the flight.
The company's General Operating Manual, page 12-5, indicated that if official weather was not available, "personal observation or other persons competent to supply appropriate observations" were permitted.
A search of official weather briefing sources, such as Lockheed Martin Flight Service and Direct User Access Terminal Service, indicated that the accident pilot did not request an official weather briefing before the flight.

On May 4, 2017, the Alaska State Troopers coordinated a recovery mission with members of the Alaska Mountain Rescue Group. The National Transportation Safety Board (NTSB) did not travel to the site due to the remote location and hazardous terrain.
According to information and photographs provided by the recovery crew, the wreckage came to rest in deep snow about 2,993 ft msl on the west face of a steep, featureless mountain in the Alaska Peninsula National Wildlife Refuge. It was located about 500 ft from the top of the mountain ridge and partially submerged in the snow on its left side with the nose section under the snowpack (see figure 4). The fragmented wreckage was contained in an area about 100 ft long by 35 ft wide, on a heading of about 031° true, with the right wing separated and located about 40 ft forward of the main wreckage and a trail of debris about 30 ft behind the empennage. The initial impact area was indicated by a narrow, 30-ft-long curved indentation in the snow about 65 ft behind the wreckage, indicative of a wing tip strike.

A postrecovery examination revealed structural damage to the area of the fuselage between the wing spar connections, a large hole and extensive buckling on the left side of the fuselage cabin and buckling on the left rear fuselage. The forward fuselage and cockpit were separated during recovery and exhibited fractures and inward compression deformations in the structure.
The right wing separated from the fuselage inboard of the wing attachment points with a section of the fuselage attached and spar deformation in a forward direction. The left wing exhibited separation at the forward attachment point with rearward overload tension signatures and compression buckling at the inboard trailing edge. The empennage was intact.
The flight controls were continuous from the cockpit to the flight control surfaces with the exception of the aileron cables, which were found separated and exhibited overload signatures.
The deice boots were intact with the exception of impact tears.
The propeller blades were each secure in the hub and exhibited trailing edge S-bending signatures consistent with engine power at the time of impact. The propeller shaft was fractured and separated from the engine and exhibited overload signatures.
The engine exhibited moderate impact damage to the exhaust duct, reduction gear box (RGB), the gas generator case, and the accessory gearbox (AGB). The power and compressor rotors rotated without noise. The compressor turbine disk and power turbine vane and disk exhibited circumferential rubbing marks. Contact marks were found between RGB first and second stage carriers, which are indicators of engine power at impact. Both magnetic chip detectors showed fuzz material on the poles. The No. 3 and 4 bearings oil scavenge pump showed severe scoring marks into the housing and on the pump gears' tips. The RGB oil scavenge pump showed similar light scoring marks and metal debris. The oil sump contained a small crushed plastic cap that was deformed in a manner that corresponded to the size and shape of the oil pump gear tips. The cap likely passed through the oil scavenge system and came to rest in the sump. Oil was present throughout the system.
No preaccident anomalies were noted with the airframe or engine that would have precluded normal operation.
Medical And Pathological Information
The Alaska State Medical Examiner, Anchorage, Alaska, conducted an autopsy of the pilot. The cause of death was attributed to multiple blunt force injuries. Toxicology testing performed at the FAA Forensic Sciences Laboratory was negative for drugs and alcohol.
Tests And Research
The airplane's Garmin GNS 530W GPS receiver had two memory cards that were removed and read on a surrogate unit at the NTSB vehicle recorder laboratory. The aviation database on each was found to be valid from April 27, 2017 to May 25, 2017.
The TAWS inhibit switch was found in the neutral (off) position. The TAWS inhibit warning light and the reset switch were removed from the instrument panel and evaluated at the NTSB materials laboratory. Electrical continuity was established for the system and the reset switch functioned normally. Radiographic examination of the light bulb filament did not reveal evidence of stretching of the filament coil, suggesting that the light was not illuminated during impact.
Organizational And Management Information
Grant Aviation, Inc., is a 14 CFR Part 135 air carrier that holds on-demand and commuter operations specifications. The company headquarters are located at Ted Stevens Anchorage International Airport, Anchorage, Alaska. At the time of the accident, Grant operated 31 aircraft at 8 primary bases within the state of Alaska.
CFIT Avoidance Program
The company implemented a CFIT-avoidance training program in partnership with the Medallion Foundation. The program manual contained policies and procedures for flat-light conditions, white-out conditions, deteriorating visibility, estimating in-flight visibility, transitioning from deteriorating visual meteorological conditions to IMC, flying on unfamiliar routes and to unfamiliar airports or landing areas, and instrument approaches. The company DO had authority for the program, and the company chief pilot had responsibility of administering the program. The program was voluntary and administered outside of regulatory requirements; therefore, the FAA did not provide oversight of the training.
The CFIT-avoidance training program stated that each pilot shall have one classroom training session and one CFIT- avoidance session in an aviation training device (ATD) each year; however, the pilot's training records indicated that his most recent ATD session was 15 months before the accident.
Operational Control Program and Flight Risk Assessment
Grant Aviation implemented a Medallion Foundation Shield Operational Control program. (The Medallion Foundation was a non-profit organization with a core mission of reducing aviation accidents in Alaska. It operated between 2002 and 2019.) The Operational Control Manual stated, "this program has been incorporated into Grant Aviation's operations for the purpose of educating and instructing applicable personnel on the requirements of operational control, implementing a system that identifies risks and associated hazards of flight operations, requires shared decisions for dispatching of all flights, and monitoring of all flight to ensure safe and efficient flight operations."
The accident pilot and dispatch agent each shared the decision to dispatch the flight. The dispatch agent performed a risk assessment of the landing areas and provided that assessment to the pilot. The pilot's procedures were to consider his qualifications, physical and emotional state, ceiling and visibility, wind, equipment, and time of day. According to the flight dispatch documents, the weather information used for the risk assessment process was almost 2 hours old and only provided landing area assessments for some of the destinations on the planned route of flight. Both the pilot and the dispatch agent signed the Flight Risk Assessment for the flight that indicated a "2 yellow" value, which was acceptable.
The risk assessment process did not consider the en route portion of the flight, such as terrain hazards or area weather hazards such as AIRMETs. The VFR weather minimums used by the company were 500 ft ceiling and 2 statute miles visibility, regardless of the terrain or weather reporting infrastructure.
Multiple company pilots stated during interviews that it was well-known that flying down the Alaska peninsula was very hazardous and pilots considered it an undesirable route due to the terrain, rapidly changing weather, and lack of weather reporting infrastructure. The DO stated during an interview that the accident flight route was acquired from another company about 3 years before, but Grant never performed a broad risk assessment of the route.
Safety Program
The company had a Medallion Foundation safety program and manual. The safety officer was responsible for administering the program, which consisted primarily of a hazard reporting structure, risk assessment process, reports and routine safety committee meetings to address the reports. One of the goals of the program was to identify hazards that are unknown, unseen, or previously ignored in the workplace before an accident or incident occurs. The director of safety was responsible for ensuring that the tasks or functions of the safety program were successfully accomplished, including company safety meetings, audits, employee communication, hazard and risk analysis, and scheduling required training. The program was reactive and responded to inputs from employees, rather than a proactive safety risk management model that would be present in a robust safety management system (SMS). According to the DO, the safety officer position had been vacant since February. The DO assumed the safety officer duties after the accident.
Additional Information
CFIT Manual
Grant's CFIT Avoidance Manual defined CFIT as, "when an airworthy aircraft under the control of the flight crew is flown unintentionally into terrain, obstacles or water, usually with no prior awareness by the crew."
Flat Light
Flat light was defined in Grant's CFIT Avoidance Manual as "an optical illusion that causes pilots to lose their depth-of-field and contrast vision. It is usually accompanied by overcast skies inhibiting any good visual clues. …occur primarily in snow covered areas. Flat light can completely obscure features of the terrain, creating an inability to distinguish distances and closure rates." Company policy stated that VFR flight in flat light conditions was allowed provided the pilot recognized the conditions and increased minimum flight altitude to 2,000 ft above the highest obstacle within a horizontal distance of 5 miles if operating over mountainous terrain. Pilots also had the option of obtaining IFR clearance and continuing the flight.
Deteriorating Flight Visibility
Deteriorating flight visibility was defined in Grant's CFIT Avoidance Manual as "the reduction of forward horizontal distance due to weather phenomena, such as rain, snow, fog, clouds, blowing snow, mist, virga, dust, or any other conditions that would reduce the pilot's ability to see from the cockpit."
The CFIT avoidance manual stated on page 2-4 that "it is Grant Aviation's policy that pilots operating in deteriorating visibility under VFR can continue to do so as long as the minimum ceiling and visibility requirements for VFR flight are observed. At any point during the flight if the minimum ceiling and visibility requirements for VFR flight are no longer observed pilots shall "refer solely to their instruments and ensure they have adequate ground clearance. Once stabilized they shall execute a stabilized altitude course reversal with a standard rate turn away from obstructions and rising terrain and divert to more favorable VFR conditions. Those pilots and aircraft that are capable of IFR flight have the option of obtaining an IFR clearance…"
Scheduled 14 CFR Part 135: Air Taxi & Commuter
Accident occurred Monday, May 01, 2017 in Chignik Lake, AK
Aircraft: CESSNA 208B, registration: N803TH
Injuries: 1 Fatal.
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 1, 2017, about 1350 Alaska daylight time, a turbine-powered Cessna 208B Grand Caravan airplane, N803TH, sustained substantial damage after impacting steep, mountainous terrain about 8 miles south of Chignik Lake Airport, Chignik Lake, Alaska. The airplane was being operated as Flight 341 by Grant Aviation, Inc, Anchorage, Alaska, as a scheduled commuter flight under the provisions of 14 Code of Federal Regulations (CFR) Part 135 and visual flight rules (VFR). The airline transport pilot, the sole occupant, sustained fatal injuries. Visual meteorological conditions prevailed at the airplane's point of departure, and company flight following procedures were in effect. Flight 341 departed Port Heiden Airport, Alaska, at 1305, destined for Perryville Airport, Perryville, Alaska.
Flight 341 originated at the King Salmon Airport, Alaska, with one passenger who disembarked at the Port Heiden Airport. The scheduled flight continued to the Perryville Airport, which was about 80 miles away, with 1,322 lbs. of mail and no passengers. According to the director of operations for Grant Aviation, at 1353 he received a notification from the US Coast Guard Rescue Coordination Center (RCC) Juneau, of a signal from a 406 megahertz (MHz) Emergency Locator Transmitter (ELT) that was registered to N803TH. The Director of Operations initiated the company's overdue aircraft procedures.
According to the US Coast Guard District 17 Command Center, the initial ELT signal was received from the COSPAS/SARSAT system at 1353. RCC Juneau initiated a search mission that included a HC-130 airplane and MH-60 helicopter from Air Station Kodiak, which is located about 275 miles northeast of the initial ELT position. At 1730, the wreckage was located and a rescue swimmer was hoisted down to the site. The crewman determined that the pilot was deceased. The crew could not extricate the pilot due to limited resources, time, fuel and deteriorating weather.
The Alaska State Troopers coordinated a recovery mission conducted on May 4 that included a Coast Guard MH-60 from Air Station Kodiak, and volunteer members of the Alaska Mountain Rescue Group. The remains of the pilot were removed from the scene and transported to a secure location. The wreckage will be recovered and examined at a future date.
According to information and photographs provided by the recovery crew, the wreckage came to rest in deep snow at about 2,993 feet on the west face of a treeless, steep mountain in the Alaska Peninsula National Wildlife Refuge of the Aleutian Range. It is located about 500 feet from the top of the mountain ridge and partially submerged in the snow on its left side with the nose section under the snow pack. The fragmented wreckage was contained in an area of about 100 feet by 40 feet, on a heading of about 030 ° magnetic, with the right wing separated and located about 40 feet forward of the main wreckage. The wings and fuselage sustained substantial damage.
At 1239, an aviation special weather report (SPECI) from the Chignik Airport (the closest weather reporting facility) reported, in part: wind variable at 4 knots; visibility 10 statute miles, light rain; sky condition, overcast at 1,700 feet; temperature 39 ° F, dewpoint 36 ° F; altimeter, 29.51 inHg.
Gabriele Cianetti
The pilot was identified Tuesday morning by Alaska State Troopers as 54-year-old Gabriele Cianetti of Anchorage. Grant Aviation President Bruce McGlasson described Cianetti as an experienced bush pilot who worked at several other Alaska aviation companies before spending about 2 1/2 years with Grant.
An emergency locator transmitter signal from the Cessna 208B prompted the launch of an MH-60 Jayhawk helicopter crew from Coast Guard Air Station Kodiak, the Coast Guard said in a post on its Alaska Facebook page.
"The Jayhawk crew lowered a rescue swimmer to assess the wreckage but unfortunately the pilot did not survive," the Coast Guard wrote.
Cianetti was a dual citizen of the United States and Italy, where his family resides, McGlasson said. He was not married and did not have kids, but Cianetti was close with employees and customers, particularly those out of his home base of King Salmon and the crew in Dillingham, he said.
Petty Officer 1st Class Brent Flanick, with the Coast Guard's 17th District command center, said the Cessna was on a flight from Port Heiden to Perryville when the locator signal was detected just before 2 p.m.
"They spotted the wreckage at about 3,000 feet on one of the mountains," Flanick said.
McGlasson said Cianetti was on an "extra session flight." The pilot was taking mail to communities on and around the Alaska Peninsula, he added, "he was heavily loaded with cargo, mostly mail, some commodities."
A single passenger had been flying with Cianetti but got off the plane at Port Heiden, McGlasson said.
The helicopter crew was able to electronically confirm the plane's location, about 225 miles southwest of Kodiak, by about 4:20 p.m. Cloud cover prevented the Jayhawk crew from lowering a rescuer for another two hours.
Clint Johnson, the National Transportation Safety Board's Alaska chief, said the crash site was in steep, snow-covered terrain roughly 8 miles south of Chignik Lake. Investigators and Alaska State Troopers were hoping to travel there Tuesday, but cloudy weather may continue to hinder their efforts.
"Right now, we're trying to form a plan on how to get there and get this done," Johnson said.
Grant's Dillingham and King Salmon facilities were closed Tuesday in response to Cianetti's death, the company said on its Facebook page. Counselors will visit the locations Wednesday, McGlasson said.
"As the NTSB investigates the cause of the crash, we at Grant Aviation encourage our employees and customers to reach out to one another to share comforting words and memories of Gabe," Grant officials wrote.
Cianetti's remains were not recovered Monday, Flanick said.
Troopers have identified the deceased as 54-year-old Gabriele Cianetti, of Anchorage. His next of kin has been notified.
Updated at 10:05 a.m. on Tuesday, May 2
The pilot and sole occupant in a Cessna 208B operated by Grant Aviation was found dead south of Chignik Monday evening, according to an updated Tuesday Alaska State Trooper dispatch.
The wreckage was discovered at a 3,000-foot elevation about “228 miles southwest of Kodiak,” Petty Officer John Paul Rios with the U.S. Coast Guard said.
The plane was headed from the small, Alaska Peninsula village of Port Heiden to Perryville when the emergency locator transmitter (ELT) went off south of Chignik around 2 p.m., according to Clint Johnson, Alaska region chief for the National Transportation Safety Board (NTSB).
Troopers said that Grant Aviation confirmed they had an overdue aircraft.
The Coast Guard launched a C-130 Hercules airplane and a MH-60 Jayhawk helicopter to search the area.
The wreckage was discovered at 5:49 p.m., on a steep mountain slope near Perryville.
Troopers said efforts to recover the body and wreckage are ongoing. In a Tuesday morning phone call, Johnson said because of the terrain, the recovery was going to be a challenge.
