CEO of Momentum Engineering, LLC
Michael "Troy" Richardson
Leading Expert Witness in Zipline Accidents with over 20 Years Experience. Bachelor in Engineering, National Board Certified Welder, Machinist, Three United States Zipline Patents, Built Small & Large Ziplines, Third-Party Trainer, and was an Owner/Operator/Trainer for his Zip Line Tour in 2009
My company AA Machining & Welding (AAM&W) started building zip lines in about 2000 when Park City Mountain Resort asked my company to develop a passive braking trolley. My first zipline trolley patent issued in 2003. AAM&W built the zip line towers, passive braking trolleys, and developed the first spring pack as an Emergency Arrest Device (EAD) for the system. In 2016, after forming my new company, Momentum Engineering developed a new trolley shortly after I found myself inventing better, safer, compact braking systems. The EAD spring pack system is the most reliable emergency brake in the zip line industry, according to a white paper in January 2017. In 2016 I developed my first handheld passive braking trolley and a new spring system the patent issued in 2019
As an Expert Witness, I have been retained in 25+ states and in five short years, assisted attorneys in over 35+ matters for both the Plaintiff and Defendant.
As an expert witness and inventor, I think quickly. I am confident and trustworthy with the ability to convey specialized knowledge effectively.
I am an active participant in standard generating organizations. Including; American Society for Testing and Materials ASTM Committee F24 Amusement Rides & Devices, ASTM Committee F15 Consumer Products, ASTM F24.61 F2959 Aerial Adventure Courses, Association for Challenge Course Technology, and was a board member with the American National Standards Institute/Professional Ropes Course Association.
My motto is: "Safety is NO Accident."

Safety is No Accident
Ziplines are not toys. They are complex, high-velocity pieces of equipment that require maintenance, care, and knowledge. Sadly, too many people ignore the safety protocols developed by engineers—if they bother learning them at all. When injuries occur on a zipline or aerial adventure course, you’ll often find that human error was, at some point, responsible. As a world-class designer and your expert witness, my goal is to impart one thing: there are no accidents in safety.
