This document presents basic technical description of the five-place MD Helicopters, Inc.
(MDHI) MD 500E helicopter built in Mesa, Arizona, USA. It is designed to provide high-level
technical information of the helicopter, advantages / features, and configurations. For more
detailed information, an MD 500E Product Specification is available by contacting one of the
Sales Team Members listed below.

The MD 500E light turbine helicopter allows easy configuration conversion from a five-place
personnel transport to a utility helicopter. With a five-blade main rotor and either a 420-shp
Rolls-Royce 250-C20B turbine engine or an optional 450-shp Rolls-Royce 250-C20R/2 turbine
engine, the MD 500E is the best performing helicopter in its class.
The MD 500E has a relatively small diameter main rotor system and a short tail with a high
horizontal stabilizer with two tip plates to provide vertical, longitudinal, and lateral stability in
forward flight. Rotor blades can be folded to allow confined-enclosure storage.
The MD 500E is certified for single pilot operation under visual flight rules / visual
meteorological conditions.
