An Airlift Northwest helicopter tipped onto its side Tuesday night while attempting to land near Kachess Lake during a medical evacuation, prompting investigations by federal aviation authorities.
The helicopter crew escaped without injury and successfully extricated themselves from the aircraft after it rolled onto its right side around 11:02 p.m. near Interstate 90’s Exit 62, according to the Kittitas County Sheriff’s Office.
The medical helicopter had been dispatched to assist with an injured camper near Little Kachess Lake after deputies responded to a missing person report around 8 p.m. Searchers located the man, who had accidentally cut himself severely enough to require air ambulance transportation.
The aircraft attempted to land at the north end of Kachess Lake to evacuate the injured camper when the landing incident occurred. The Federal Aviation Administration and National Transportation Safety Board have been notified and dispatched investigators to determine the accident’s cause.
Following the helicopter mishap, the injured camper was transported by ground ambulance to a hospital in the Snoqualmie area for medical treatment, deputies confirmed.
The incident highlights challenges faced by medical aviation crews operating in remote wilderness areas, particularly during nighttime operations when terrain visibility and landing conditions can be compromised.
Airlift Northwest provides critical emergency medical services throughout the Pacific Northwest, often serving as the primary means of rapid medical evacuation from remote locations where ground ambulances cannot easily access patients.
The Kachess Lake area, located along the Interstate 90 corridor east of Snoqualmie Pass, is popular with campers and outdoor enthusiasts but presents logistical challenges for emergency responders due to its remote location and varied terrain.
NTSB investigators will examine factors including weather conditions, terrain characteristics, mechanical systems, and crew procedures to determine what caused the helicopter to tip during landing. Such investigations typically take several months to complete.
The successful crew extraction without injury demonstrates the effectiveness of helicopter safety systems and crew training protocols designed to protect occupants during emergency situations.
Despite the aircraft mishap, emergency responders successfully completed their primary mission of providing medical assistance to the injured camper, who received necessary hospital treatment following ground transportation.
