Flight Conducted Under:
Part 133: Rotorcraft Ext. Load
On March 8, 2019, about 0705 Pacific standard time, a Bell UH-1B helicopter, N64RA, collided with mountainous terrain near Forks, Washington. The commercial pilot was fatally injured. The helicopter sustained substantial damage to the fuselage, tail boom, and drivetrain. The helicopter was registered to and operated by Iron Eagle Helicopters under provisions of Title 14 Code of Federal Regulations Part 133, as an external load operation. Visual meteorological conditions prevailed, and no flight plan was filed for the off airport local flight. The flight originated from a remote location and flew to the contracted logging site about 1/2 miles to the south-west.
According to the logging project manager, this was the first flight of the day for the pilot. The grapple logging operations from the helicopter uses a hydraulic log grapple affixed to a 180 ft Kevlar long-line.
According to one witness, who is a helicopter mechanic, he assisted the pilot in the pre-flight inspection of the helicopter. The mechanic remained in the area and observed a normal engine start, run up and take off. Afterwards the mechanic continued with his morning activities and heard three successive distress calls from the pilot over the company communication radio. The mechanic and three other employees began a search of nearby emergency landing areas. After finding the emergency landing areas empty, one employee hiked to the site where the helicopter was scheduled to perform the grapple logging operations and found the wreckage.
The wreckage was located in a heavily forested, mountainous area about ½ mile north east of the point of departure. The first identified point of impact was directly underneath the wreckage. The debris field was small, consisting of small portions of the main rotor scattered about 50 ft away from the main cabin.
The cabin came to rest inverted on a heading of about 100° magnetic. The tail boom and tail rotor had separated but remained alongside the fuselage. The main rotor and transmission were displaced aft over the engine.
The grapple and long-line remained attached to the cargo hook of the helicopter and extended uphill away from the wreckage.
There was no post-impact fire. The wreckage was relocated to a secure facility for further examination.
