R66 Turbine Utility
Class Leading Reliability & Precision
The R66 Turbine Utility's core distinction lies in its capacity for external load operations, featuring a standard Onboard Systems cargo hook installation that allows for a maximum external load of 1200 lb (544 kg).
This configuration increases the maximum combined helicopter and load weight (Maximum Gross Weight) to 2900 lb (1315 kg). Furthermore, it grants operational flexibility by allowing solo flight from either the right or left pilot seat, unlike many STC installations.
Standard Safety Features
Safety and monitoring for lift operations are prioritized with unique instrumentation, including supplemental engine torque and gas temperature gages along with a hook-load meter located in the sill of the left door, enabling the pilot to monitor critical engine parameters while observing the lift operation.
The design also features energy-absorbing seats, a 4K cockpit camera, and a crashworthy fuel system that minimizes leakage risk. Additionally, the helicopter includes a Fuel status light that indicates approximately 12 gallons of fuel remains before the 5-gallon low-fuel caution.
Strategic Cockpit Design
The cockpit is tailored for utility missions with specialized controls, including an upgraded left-side cyclic grip with hydraulic and radio switches and a left-side collective control with a start button. The pilot has command over external devices via left- and right-side electrical and mechanical load releases and switches on the left and right cyclic grips to activate belly circuits.
Essential monitoring is provided by a load weighing system, and crew safety during open-door operations is ensured with interior anchor points at forward door posts for attaching a safety tether or harness.
Performance Parameters
The Utility model is optimized for high utilization and reduced downtime, featuring life-limited components with 2000+ hour service lives, a 2000-hour airframe TBO, and a 2000-hour/3000-cycle engine TBO. Due to the increased gross weight, the operational envelope includes a Maximum Operating Density Altitude of 7,000 ft when the helicopter weight and load is above 2700 lb.
