When was the Robinson R66 certified?

FAA Part 27 type certification was granted in 2010 under TCDS H47NM, with first customer deliveries the same year. The prototype first flew in 2007. The type is the first turbine helicopter from Robinson Helicopter Company — historically a piston-helicopter manufacturer with the R22 and R44.

How does the Robinson R66 compare to the Bell 206 JetRanger?

Both are five-seat single-turbine FAR Part 27 helicopters in the same training and EMS / corporate segment. The 206 carries more historical industry depth (~7,700 built since 1967) and Rolls-Royce M250 engine support, but production ended in 2010 / 2017. The R66 is in current production at Torrance, California, burns less fuel (~17 gph versus ~25 gph on the 206B's M250-C20), and integrates naturally with Robinson piston-helicopter fleets. Operators choose between them on production status, fleet integration, and hourly operating-cost basis.

What engine does the Robinson R66 use?

The R66 uses a Rolls-Royce RR300 turboshaft — a 300 shp engine derated to 270 shp continuous to support reliability and TBO planning. The engine burns Jet-A and is a Rolls-Royce engine specifically developed for the R66 programme, with the original RR300 designation reflecting the new Rolls-Royce naming convention for the turboshaft line.

Is the Robinson R66 a good turbine-transition trainer?

The R66 is widely used by schools already operating the broader R22 / R44 piston Robinson fleet because the maintenance practice, two-bladed teetering rotor system, and overall design philosophy carry across. Schools running a Robinson piston fleet gain a turbine-transition platform that integrates with the existing factory support, training network, and operator manuals.

How much does a Robinson R66 cost?

New-build R66 list pricing has typically sat in the 950,000 to 1,100,000 USD range depending on options. Hourly direct operating cost is typically in the 500 to 750 USD per hour range including Jet-A burn, engine reserves, and Robinson's lifecycle-overhaul dynamic-component reserves — below typical Bell 206 hourly cost at comparable utilisation. School cost models differ; validate against current Robinson dealer quotes.

Cockpit & avionics

Cockpit typehybrid
Autopilot commonly availableYes
Typical packages
- Garmin GTN 650 / G500H TXi— current factory option
- Aspen Evolution / King KX-165— earlier R66 airframes and retrofits
Training note
The current R66 NxG configuration ships with a full Garmin glass cockpit and Robinson's two-axis digital autopilot (which Robinson markets as the 'industry's first two-axis autopilot' in this helicopter segment) as standard. Earlier R66 Turbine airframes carried analog primary instruments with optional Garmin GTN navigators and could be retrofit with the autopilot.

Why is the R66 Turbine popular?

Structured popularity-driver evidence. Each axis below carries one factual statement; we don't grade, the facts speak.

Industry network effects

Robinson Helicopter Company already supports the world's most-produced civil helicopter line (R22 / R44, more than 11,500 airframes built). Schools operating R22 / R44 piston fleets can transition students into the R66 turbine within the same factory support, maintenance practice, and instructor network.

Fuel future-proofing

Rolls-Royce RR300 turboshaft burns Jet-A — same fuel as the broader turbine fixed-wing fleet and outside the FAA EAGLE / California UNL94 leaded-fuel transition exposure that constrains the legacy 100LL piston-helicopter fleet.

Regulatory fit

FAR Part 27 / EASA CS-27 turbine helicopter; five-seat configuration places the R66 in the same training and EMS / corporate operating segment as the Bell 206B JetRanger but in current production.

Operating economics

Roughly 17 gph Jet-A cruise burn on the RR300 — materially lower than the Bell 206B's M250-C20 at roughly 25 gph — combined with Robinson's simplified two-bladed rotor system and lifecycle-overhaul philosophy give the R66 a lower total operating-cost profile than legacy single-turbine helicopters in the same segment.

Before you buy more aircraft

The next airframe is rarely the highest-leverage move.

Flight school revenue is a function of three things — utilisation, dispatch reliability, and student progression — that multiply rather than add. Most schools running below 850 hours per aircraft per year have hidden capacity worth more than the next purchase, already paid for and sitting on the ramp.

How flight schools track this aircraft in Aviatize

Schools operating the R66 typically configure it in Aviatize as a single airframe with the Rolls-Royce RR300 turboshaft as an engine sub-component and Robinson's lifecycle-overhaul dynamic components (transmission, main rotor, tail rotor) modelled as child resources for time-on-component tracking. Block-hour billing uses Hobbs time. Pilot-currency rules should gate the resource on a current rotorcraft category certificate and on completion of the Robinson factory safety course where the operator's training programme requires it.

High confidenceLast reviewed 2026-05-26

Powerplant, certification, and configuration data attributed to Robinson Helicopter Company and FAA TCDS H47NM. Acquisition-cost figure is an approximate band consistent with public dealer listings; helicopter takeoff / landing roll fields populate as 0 because the airframe operates from a hover.
