ANCHORAGE (KTUU) UPDATE:
The National Transportation safety board says the crash happened around 10 A.M. Saturday.
Officials say friends of the pilot launched a private search for the plane initially.
"They did find the airplane." said Alaska NTSB Chief, Clint Johnson.
"The flight was intended to shuttle a group up to a cabin up in that area. They had completed that first shuttle and the pilot was on the way back to Sand Lake to do the last shuttle of two people and that's when the plane became missing," Johnson said.
Johnson said two NTSB investigators along with troopers are going back to the scene Sunday to further investigate the crash.
Troopers say the Alaska Rescue Coordination Center responded to a plane crash near the Yentna River.
R.C.C. received the report at around 2 P.M. Saturday of the downed fixed wing aircraft.
Troopers said R.C.C. found the aircraft along with the deceased pilot,75 year old, Donald Wayne Frantz.
The Alaska State Troopers and Talkeetna Fire and Rescue transported Frantz to Lake Hood in Anchorage were he will be turned over to the State Medical Examiner’s Office.
Troopers say no other occupants were in the downed aircraft and the NTSB is continuing their investigation.
