McDonnell Douglas MD 600N Helicopters for Sale
The McDonnell Douglas MD 600N is the most powerful and spacious member of the legendary 500/600 series family — a six-to-eight seat single-engine turbine helicopter that takes the proven NOTAR anti-torque system and scales it up to a larger, more capable airframe. Entering service in 1998, the MD 600N was designed to address operator demand for a larger-cabin NOTAR helicopter that could carry more passengers and cargo than the MD 500 series while retaining all the safety and noise advantages that made the NOTAR system so compelling for law enforcement, EMS, and urban operations.
NOTAR at Scale
The MD 600N uses the same NOTAR principle — pressurized air through a Coanda-effect slot and rotating directional control jet — that proved itself in the MD 500 series and MD Explorer, but engineered for a helicopter with 20% more cabin volume and 30% higher gross weight. The result is a helicopter that can carry a pilot and up to seven passengers in high-density configuration, or five in comfortable executive seating, while operating with dramatically less noise and dramatically more safety in confined urban environments than any conventional tail-rotor helicopter in its class.
Allison 250-C47M Engine
Power comes from the Rolls-Royce (Allison) 250-C47M turboshaft delivering 375 shaft horsepower — part of the same 250-series family that has proven itself across the entire MD/Hughes 500 line and the Bell 206 family. FADEC engine control provides precise power management, and the 250-series' extensive worldwide overhaul infrastructure keeps maintenance costs competitive. Cruise speed reaches approximately 135 knots, with a range of approximately 330 nautical miles on standard fuel.
Operator Applications
- Law enforcement — The 600N's quiet NOTAR system and six-to-eight seat capacity make it ideal for tactical law enforcement units requiring both surveillance capability and personnel transport in a single airframe.
- EMS — Spacious cabin accommodates stretcher, medical equipment, and full crew with room for a second patient position if required.
- Corporate shuttle — VIP-configured 600Ns serve executive transport roles where passenger capacity beyond five is important and urban operating noise is a consideration.
- Utility and government — Larger payload capacity than the 500 series opens additional utility roles while retaining NOTAR's safety advantages.
