A helicopter pilot died Monday while assisting in efforts to fight the White River Fire.  According to a statement from fire officials posted late Monday night on the Inciweb fire information page, a Type 1 Kmax helicopter was conducting bucket drops on the fire when the accident occurred.  The Wasco County Sheriff’s Office and Forest Service air and ground resources responded to the crash site.  The National Transportation Safety Board and the Federal Aviation Administration have been notified and will conduct an investigation into the accident.  The identity of the pilot has not been released.  The Forest Service placed containment of the White River Fire in the Mt. Hood National Forest at 5% on Monday.  Officials reported Monday that the size of the fire was dropped to 1,102 acres after resolving a mapping error and new infrared data.  Fire officials say firing operations have started along both the east and west ends of the fire toward the White River, and work to improve contingency lines will continue.
