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 August 23, 2017, about 2245 Alaska daylight time, a tundra tire-equipped Piper PA-18 airplane, N1905A, was destroyed after impacting remote tree-covered terrain while en route to Merrill Field, Anchorage, Alaska about 31 miles northwest of Tyonek, Alaska. The pilot, the only occupant, died at the scene. The airplane was registered to and operated by the pilot as a 14 Code of Federal Regulations Part 91 visual flight rules personal flight. Dark night, visual meteorological conditions were reported at the Kenai Municipal Airport, Kenai, Alaska about 8 minutes after the accident time, and no flight plan was filed. The Kenai Municipal Airport is located about 44 miles southeast of the accident site. 

The flight originated from a remote airstrip in mountainous terrain near Telaquana Lake, located in the Lake Clark National Park and Preserve. 

In a conversion with the wife of the pilot on August 28, she reported to the National Transportation Safety Board (NTSB) investigator-in-charge (IIC) that the purpose of the flight was for a solo sheep hunting trip. The pilot departed from Merrill Field on August 19 about 1630 and arrived at the remote airstrip about 1930. The wife reported the length of the hunting trip was open ended, with no set return date. On August 23, about 2100 the pilot contacted the wife via a satellite phone and asked her to retrieve various weather information. The wife instructed the pilot to call her back in about 5 minutes and she would provide him the requested weather information. The pilot never called the wife back. About 2220, the wife reported that she received a text message from the pilot stating he was flying over Kenibuna Lake and he should be home around 2300. 

Sunset on the day of the accident was 2137; the end of civil twilight was 2227.

About 2245, the U.S. Air Force Alaska Rescue Coordination Center received a 406 MHz emergency locator transmitter (ELT) signal. 


On August 24, a U.S. Air Force HH-60G helicopter was dispatched to the 406 MHz ELT coordinates and confirmed the location of the wreckage about 0625, located in remote-tree covered terrain about 1 quarter mile south of the Chakachatna River. On August 24, the NTSB IIC and the Alaska State Troopers traveled to the accident site via helicopter. The wreckage was recovered and transported to a secure facility for future examination of the airframe and engine.

ANCHORAGE, Alaska (KTUU) - Update - Aug. 25., 3:45 p.m.:

On Friday, at approximately 3:25 p.m., the State Medical Examiner's Office identified the deceased pilot as 35-year-old Jason Walkush of Anchorage, according to the Alaska State Troopers. Additionally, AST says next-of-kin have been notified.

According to NTSB's Clint Johnson, the body was recovered Thursday evening. And now, the investigation has entered the "wreckage recovery phase," he said.

In the upcoming week, Johnson said NTSB will attempt to arrange a helicopter recovery of the plane wreckage. From there, he said the parts will be dropped off in either Anchorage, or Wasilla, where the investigation will continue.

ANCHORAGE, Alaska (KTUU) - Update - Aug. 24., 4:05 p.m.:

NTSB received notification of a plane crash, between Tyonek and Port Alsworth, at approximately 11 p.m. Wednesday, according to NTSB Alaska Region Chief Clint Johnson. He confirmed the death of the pilot, after the Rescue Coordination Center arrived on scene Thursday afternoon.

More specifically, the plane crashed about 50 miles west of Tyonek, near the east end of Chakachamna Lake, according to Johnson.

The identity of the pilot is not being released currently, as AST is still working on notifying next-of-kin, said Johnson. He was able to confirm that the pilot was the sole occupant of the plane.

Additionally, Johnson described the downed Piper PA-18 as being personal-use.

"Things are very preliminary at this point," said Johnson. "We're tying to put those pieces of the puzzle together, but we just started the investigation."

While NTSB does not yet know how, or why, the plane crashed yesterday evening, Johnson did explain that rescue teams were able to locate the aircraft, because the plane emitted a "406 ELT (Emergency Locator Transmitter) hit."

By tomorrow morning, Johnson is hopeful that investigators will have more information about the crash.

"State Troopers and NTSB are actually on scene, as we speak right now," Johnson told KTUU. "They will be there pretty much all day recovering the remains and also starting our initial investigation."

This is a developing story and will be updated with further information.

Original Story - Aug. 24, 12:47 p.m.:

A plane has crashed between Tyonek and Port Alsworth and trooper helicopters are en route to locate the sole occupant aboard.

The plane went down sometime on Wednesday and did receive a search and rescue call overnight.

"There's a lot that we don't know right now," said Clint Johnson, Alaska chief for the National Transportation Safety Bureau.

"Probably about three minutes ago, the trooper helicopters took off to head to the crash site," Johnson said Thursday afternoon.

Right now, the identity and condition of the pilot and sole occupant are not yet being disclosed. The damage to the plane is not known.

The plane in question, a Piper PA-18 Super Cub, is "a very very popular aircraft in Alaska," Johnson said.

The cause of the crash is not immediately available, but Johnson noted that weather in the region is not favorable and has slightly slowed the investigation.

While the general area of the crash is known, investigators do not have a concrete location of the downed aircraft. The plane's flight path and departure location are also not available at this time.
