A plane crash near the Happy Valley airstrip, north of the Brooks Range, Wednesday afternoon left two people including a child seriously injured, according to the National Transportation Safety Board.

NTSB spokesperson Clint Johnson says the agency was informed shortly after 3 p.m. that a Helio Courier, a small plane capable of short takeoffs and landings, crashed on takeoff at about 2:20 p.m. from an airstrip near a haul road in the area.

Johnson said Thursday that the plane's pilot was uninjured in the crash, but the other two people on board suffered serious injuries. All three occupants, whom Johnson described as a family, were flown to Anchorage for treatment.

The 1973 plane is registered to Jago River Holdings LLC in Fairbanks.
