The amusement ride industry has been dealing with the issue of accessibility of riders with handicaps. The ADA requirements are typically based on wheelchair accessibility. The industry is faced with a number of legal challenges.

On June 11 and 12, 2013, I participated as an expert, in the first controlled , quantitative testing of handicapped young people on amusement rides. Project Accessibility to Amusement Parks for People with Special Needs was a joint effort including, but not limited to, the following Italian organizations, National Institute of Public Health; National Association of Operators of Traveling Shows; Bambino Gesu Pediatric Hospital; National Association for People with Down’s Syndrome; Active Consortium of Special Skills; European Association Amusement Supplier Industry; IAAPA Europe; Planet Down; V4A Quality Brand for Accessible Tourism; Miragica Amusement Park; Leolandia Park, National Fire Brigade and about 30 invited experts from Europe, Canada and the United States.

The testing was conducted with a group of Down syndrome young people and a control group of similar age non-handicapped people. In addition to the Down syndrome young people there were two, special wheel chair-bound participants. The rides used for testing had no special accommodations for handicapped riders. The rides included simple round rides, small and large log flume rides to a 100 foot drop tower and several roller coasters including a spinning wild mouse type. The testing to measure individual rider stress was accomplished using the collection of cortisol samples from all participants before and after each ride. The results of the clinical testing are not yet available.

Planning is now underway for a follow-up program to continue the quantitative and technical work of Project Accessibility to Amusement Parks for People with Special Needs. From a personal point of view this experience gave me a better insight into the joy this unique group of riders showed by having access to amusement rides. My attitude shifted from challenges to potential solutions for accommodation. I will be continuing my participation in this ground-breaking project.

I have been developing and presenting amusement ride and device training classes for over 15 years. These classes have been taught at schools put on by National Association of Amusement Ride Safety Officials, Northwestern Showmen’s Association, International Codes Council EDUCODE and Technical Standards and Safety Authority (Province of Ontario, Canada). Many of the classes are approved by the State of California and NAARSO for “self-directed” continuing education hours. The classes are approved for CEU’s issued by Darden College of Old Dominion University. These classes include but are not limited to:

HYDRAULICS: Basic Hydraulics, Hydraulic Components, Advanced Hydraulics, Hydraulics for Ride Inspectors, Hydraulics Troubleshooting

PNEUMATICS: Basic Pneumatics, Advanced Pneumatics

Q: Have any of your accreditations ever been investigated, suspended or removed? (if yes, explain)
A: NO!
Q: On how many occasions have you been retained as an expert?
A: I have been retained as an expert in thirty three cases. Two of these cases were major amusement ride patent cases.
Q: For what area(s) of expertise have you been retained as an expert?
A: AMUSEMENT RIDES: Based on experience with Disney Imagineering, Universal Studios Hollywood (USH), amusement park and carnival rides, I have been able to provide litigation support and expert services covering all technical and operational aspects of all levels of amusement rides. I have developed inspection check-lists for over 200 amusement rides. I have established functional baselines for major, one-of-a-kind park rides, coasters, thrill rides, family rides and kiddie rides that can be used as references in litigation support.

MOTION SIMULATORS: I am listed inventor on three US and three European patents on the use of Motion Simulators in the amusement industry. I designed and built the first, successful, large cabin, entertainment, motion simulator system. The system was replicated by Disney for their Star Tours simulators. Based on this expertise I was qualified as a litigation support specialist in a patent infringement suit related to entertainment motion simulators. I was also qualified as an expert witness in a related patent malpractice case.

SPECIAL SIMULATION: I am currently involved in the development of codes and standards compliance and safety assessment of “Live-Fire” training simulation props and systems for a state of the art Fire Department Training Evolution facility. This work is based on my extensive experience I the operation and maintenance of “Live-Fire” effects used in the Amusement park industry.

PASSENGER SAFETY EQUIPMENT: As a litigation support specialist I have successfully tested, evaluated and conducted fault-tolerance analysis of safety restraints and systems on amusement rides and devices for a number of attorneys. I recently filed a U.S. patent application on a specialized safety restraint system based on my extensive experience in the field of passenger restraint systems.

PERFORMANCE TESTING: My performance testing of amusement rides and devices has been accomplished through the use of tri-axial accelerometers and related sensor systems. Most recently I have expanded the scope of performance testing through the use of fully instrumented Hybrid III Crash Test Dummies that have been tailored to provide information in the dynamic performance of amusement rides and devices. I have been engaged as a forensic investigator, litigation support specialist and expert witness providing performance testing and analysis for several cases and a current case.

SAFETY TESTING: Modern amusement rides and devices have complex, real-time ride control systems. I have applied my aircraft and space related experience to fault-tolerance testing of amusement ride and device ride control systems. I have applied fault-tolerance testing to verify the safety of the control systems for major amusement rides. I pioneered this type of fault-tolerance testing methodology to the verification of the control systems for the original Bally’s MGM section of the Las Vegas Monorail system.

ACCIDENT INVESTIGATION: I have been called on to conduct amusement ride and device accident investigations related to injuries and fatalities involving passengers on amusement rides and devices. I was called in by the Augusta, Georgia District Attorney to investigate a ride injury where there was alleged tampering with an amusement ride. I have been called in to conduct a forensic investigation of several amusement rides that were involved in fatal accidents. In those cases I provided litigation support, expert witness services and forensic investigation services.

CODES & STANDARDS COMPLIANCE: The U.S., European and Asian amusement industries have developed a wide range of codes and standards for amusement rides and devices. There are ancillary codes and standards that applied by Authorities Having Jurisdiction (AHJ). I have incorporated codes and standards compliance assessments as part of my litigation support assignments.

RISK ASSESSMENT: Risk assessment and risk mitigation is a critical element of designing an amusement ride or device. I have conducted risk assessment reviews as part of my support of litigation and expert witness services.
