Daher handed over its first multi-mission Kodiak 100 with a Hartzell five-blade composite propeller to the North Carolina Forest Service’s aviation division. The turboprop single will be used as a “load aircraft,” carrying equipment and supplies to support aerial tanker wildfire suppression.

Daher said that the new five-blade, 96-inch-diameter propeller was designed with Hartzell’s lightweight Raptor propeller hub technology, improving performance and sustainability. Weighing 13 pounds less than the Kodiak 100’s current four-blade metal propeller, the five-blade unit reduces aircraft takeoff roll by 6 percent at maximum gross weight, is 6.6 dB quieter, and turns 200 rpm slower at maximum torque, at 2,000 rpm instead of 2,200 rpm. In addition, the new prop, with a nickel-cobalt leading edge and improved erosion protection, has a time-between-overhaul of 4,000 hours or six years, along with a six-year/4,000-hour warranty.
