Aircraft overview

The MD Helicopters MD 600N is a single engine, light turbine helicopter developed from the MD 520N, with a stretched fuselage, higher gross weight and a six blade main rotor. It first flew in 1994 and received FAA certification in 1997. Production has been limited compared with mainstream utility helicopters, but the type remains notable for its NOTAR anti torque system, which replaces a conventional tail rotor with a fan driven tailboom and directional jet thruster. For buyers, the MD 600N matters because it offers a compact footprint, a relatively roomy cabin and distinctive low external noise characteristics in a niche light utility category.

Performance & specifications

Typical published figures for the MD 600N include a maximum cruise speed of about 134 knots, a range of about 210 nautical miles and a service ceiling of 20,000 feet. Maximum takeoff weight is commonly listed at 4,100 lb, with useful load around 2,000 lb depending on equipment and configuration. Power comes from a Rolls-Royce 250-C47M turboshaft, derated for the installation. The aircraft uses a fully articulated six blade main rotor and the NOTAR system for yaw control. Buyers should evaluate actual performance against installed equipment, mission kit, density altitude and maintenance status, since these factors materially affect payload and operating margins.

Cabin & avionics

The MD 600N is typically arranged for one pilot and up to six passengers, with club style or utility seating depending on interior fit. The stretched cabin provides more passenger and baggage flexibility than the MD 520N while retaining the compact fuselage profile associated with the MD 500 family. Doors and interiors vary widely across corporate, law enforcement, utility and special mission aircraft. Avionics are usually conventional rather than factory integrated glass systems such as Garmin G1000 or Garmin Perspective. Common used examples may have BendixKing equipment, Garmin GNS 430 or 530 units, transponders, audio panels and later Garmin GTN or ADS-B upgrades.

Buying & value

On the used market, the MD Helicopters MD 600N is a specialized alternative to more common single engine turbine helicopters. Its appeal depends on mission fit, especially where cabin space, noise profile and tail rotor safety considerations are valued. Pre purchase review should focus on NOTAR system condition, fan and tailboom components, rotor blade life, engine records, time limited parts, corrosion history and service bulletin compliance. Aircraft with modern avionics, complete records, low component exposure and documented factory or approved maintenance tend to be easier to place. The main caution is market depth: fewer aircraft were built, so parts planning, mechanic familiarity and resale timing deserve careful attention.
