SEDONA, Ariz. -- A single-engine plane crashed in Fay Canyon northwest of Sedona on Sunday, killing four people, according to Yavapai County Sheriff's Office spokesman Dwight D'Evelyn.
D'Evelyn said the crash was reported by hikers in the Bear Mountain area of Sedona.
Access to the crash site was difficult due to the terrain and fire. The bodies will be airlifted out due to the remote location.
The plane is based in Flagstaff, but no identifications have been made at this time.
The fire was 25 acres and there was no containment as of Monday morning.
The National Transportation Safety Board is investigating to determine the cause of the crash.
The crash also sparked the Fay Fire, which was reported before 4 p.m. in the Red Rock Secret Mountain Wilderness area.
U.S. Forest Service spokesman Brady Smith said approximately 30 personnel were on scene Monday, including a Hotshot crew, one helicopter, an air attack unit and several agencies.
Smith said the fire has a slow to moderate progression and will likely produce a lesser amount of smoke Monday compared to Sunday.
Fay Canyon Trailhead and Bear Mountain Trailhead are both closed at this time.
No structures are threatened.
