Two men escaped life-threatening injuries after their helicopter crashed during an attempted landing Sunday morning near Arkose Ridge in Hatcher Pass.

According to Alaska State Trooper (AST) dispatch, the chopper’s pilot, 27-year old John Wiese of Palmer and a passenger were the only two occupants in the Robinson R22 helicopter. AST stated the helicopter belonged to a local business that was conducting a training flight at the time. AST, Alaska Wildlife Troopers and state park rangers from the Palmer area responded to the incident.

The Robinson R22 is a lightweight, single engine, two-seater machine weighing in at just under 900 pounds. Weather conditions were heavy overcast with a low ceiling at the time of the crash. AST reported it was ready for a full response when it received word that a second chopper, owned by the same business, responded to the scene and transported the occupants.

The National Transportation Safety Board (NTSB) was notified.

HATCHER PASS, Alaska (KTUU) Emergency crews responded to Hatcher Pass Sunday morning after reports of a helicopter crash believed to be in the area of the Arkose Ridge Formation.

Alaska State Troopers report, two people on board the helicopter have been transported with non-life threatening injuries.

Trooper spokesperson Megan Peters wrote the helicopter “apparently rolled.”

At 11:30 a.m, the National Transportation Safety Board was notified about the crash by AST.

NTSB Alaska regional chief Clint Johnson said the helicopter involved was a Robinson R22 Alpha.

Castor Aviation, a Part 91 operator, is the owner of the Robinson R22 Alpha involved, according to sister company Pollux Aviation.

Johnson said, a helicopter operator out of Wasilla made initial contact with the injured passenger and pilot, despite poor weather conditions.


Multiple agencies were responding Sunday to a report of a helicopter that went down in the Hatcher Pass area, according to the National Transportation Safety Board.

At 11:30 a.m. investigators with the National Transportation Safety Board were notified that a Robinson R22 Alpha helicopter had gone down in the area of Hatcher Pass, said NTSB Alaska chief Clint Johnson.

It was reported that two people were aboard the helicopter, and the extent of their injuries was "unknown at this point," Johnson said around shortly before 2 p.m. Sunday. "It doesn't sound life-threatening."

Alaska State Troopers spokeswoman Megan Peters said around noon that troopers, state park authorities and the Alaska Rescue Coordination Center were involved in an initial response.

As of 2 p.m. it wasn't yet clear where exactly the helicopter had gone down or what kind of damage it may have sustained.
