A Quarter Century of Engineering Excellence

Over 25 years ago, Heli-Dyne Systems was founded to provide helicopter owners/operators with the same high quality of modification and completion services offered for fixed-wing aircraft.

Since then, HDS has performed more than 700 major helicopter modifications and completions for functions as diverse as air medical, law enforcement, electronic news-gathering, utility and special-mission applications. Literally thousands of helicopters have flowed through HDS' Dallas/Ft. Worth Metroplex facilities before delivery to their new owners. Aircraft with mods designed and executed by HDS are flying on nearly every continent, performing every conceivable mission.


There are many reasons helicopter owners/operators around the world come to Heli-Dyne Systems. One is capability: HDS is a fully approved and authorized customer service center for Bell Helicopter, American Eurocopter, Agusta Aerospace, MD Helicopters and Schweizer Aircraft. "Our maintenance repair and overhaul facilities provide exceptional quality and customer service for domestic and international customers," says HDS President David Horton. Close to DFW airport, "we can provide a quick turnaround for shipment of replacement and spare parts to anywhere in the world."

With a staff of 75 licensed, factory-trained technicians, HDS' facility covers more than 32,000 sq. ft. with two hangars and a clear-approach heliport. The hangars hold sheet metal, electrical, overhaul and repair, composite, and interior shops and a paint booth.

HDS is a fully approved FAA Repair Station (Cert. No. VK1R561K) operating under FAR 145, FAR 21 and MIL-I-45208. It holds Parts Manufacturing Authority for a wide range of helicopter components and subsystems. It's been awarded more than 170 U.S. and foreign single and multiple supplemental type certificates for its PMA designs, Horton says. "We also have the FAA's approval to manufacture PMA items based on our STCs."

HDS's highly skilled engineers have developed numerous innovative helicopter-specific products. An example is the company's Dual Pivoting Litter, which is used for advanced life support missions in a broad range of turbine-powered helicopters. Also, HDS' Modular Emergency Medical System is a self-contained EMS unit that includes a DPL patient bed, two oxygen ports, two suction ports with two canisters and two vacuum pumps, and one medical air port. It can be mounted and dismounted from a helicopter in less than 15 min.

Continuing the tradition of innovation and excellence in engineering is the new EPIC (Emergency Patient In-flight Care) patient loading system now certified for the EC135 and the EC145. It is designed from the ground up to meet all the requirements of FAR/JAR 27/29 while providing unsurpassed level of service and reliability to the EMS community.

The EPIC cot is built using Hard-Anodized aircraft-grade aluminum to provide unsurpassed strength and rigidity in a lightweight design. The Hard-Anodized coating eliminates abrasion and oxidation and ensures quick and easy decontamination. The unique structural design is FAA-certified to allow the transport of medical equipment, such as the Isollete, weighing up to 300 lb. in High G-rated helicopters. This is a first in the air medical industry!!

The EPIC's 600-lb. capacity easily accommodates larger patients. The oversized wheels (6x2) with sealed caster and roller bearings provide stability and ease of mobility on all types of terrain.

HDS has developed many improvements for the EC145 and EC135 interiors and will continue to STC and PMA the different components to provide these interiors as kits. Many of these systems will be incorporated into the new Bell 429.

"Heli-Dyne Systems is recognized internationally as a center of excellence, knowledge and depth," concludes David Horton. "Most importantly, we're a company where customers come first, and our record over the last quarter century proves it." HDS can be found on the Web at
