Hamilton County Sheriff’s Office 500E to 530F Conversion Returns To Service


October 13, 2017 – Collective Magazine reported about the E-to-F conversion that Hamilton County Sheriff’s Office placed in July of this year. True to MD’s word of a twelve-week turnaround time, MD Helicopters announced the delivery and return of a FAA-certified MD 530F to the Hamilton County Sheriff’s Office located in Cincinnati, Ohio. This helicopter started life as an MD 500E that has been in operation with the department since 1989 before being shipped to Mesa, Arizona for a total makeover. With a new lease on life, and delivered as a newly certified F-model helicopter with a zero-time engine, it is ready to serve the department for another lifetime. The modernization of HCSO’s Aviation Unit via MDHI’s proven E-to-F Conversion program was announced in July of this year.

“We are excited to return this beautiful, newly certified MD 530F to the team at Hamilton County Sheriff’s Office,” said Nick Nenadovic, Vice President Aftermarket and Customer Support for MD Helicopters, Inc. “Hamilton County is one of the most tenured all-MD helicopter aviation units in the country, and it is clear that the Hamilton County team understands the capabilities and value of the MD product. We are proud to have the opportunity to support their fleet modernization efforts and play an ongoing role in their exemplary service of Hamilton and surrounding counties.” 

The E-to-F conversion program, which is an MD Helicopter’s exclusive, delivers increased hot and high-performance capability as well as an improved operational range and flight time, which is crucial for a helicopter serving in a Law Enforcement role. Some of the enhancements to the HCSO aircraft include:

  • An engine upgrade from the Rolls Royce 250-C20B to the more powerful Rolls Royce 250-C30
  • Full replacement of the blades and stabilizers
  • Installation of the Garmin G500H dual-screen electronic flight display
  • The addition of a Fargo Auxiliary Fuel Tank

In addition to the performance upgrades, MD also installed an all-new interior and updated the HCSO paint scheme to match the appearance of other department vehicles. After completing the delivery inspection and required training on the new upgrades, HCSO Chief Pilot Tim Doyle and members of his aviation team accepted delivery of the newly upgraded aircraft at MD Helicopters’ Mesa, Arizona headquarters before flying their new F-model back to Hamilton County to return it to service where it serves alongside an MD 520N in their aviation unit.

“We are looking forward to flying this truly like-new aircraft home,” said Tim Doyle, “and believe it will allow us to even more effectively support the officers of the Hamilton County Sheriff’s Office, City of Cincinnati, and the various municipalities and Police Departments within Hamilton County. This aircraft will allow us to continue our legacy of providing exceptional public safety to our citizens for many years to come.”

“This program has been an outstanding resource for E-model operators to affordably upgrade the capability of their aircraft with minimal downtime,” Nick Nenadovic concludes. “It is our absolute honor to transform these proven performers into essentially new aircraft, and return them to the operators who love them as much as we do.” 

The Hamilton County Sheriff’s Office is responsible for providing primary airborne law enforcement support to the 800,000+ residents and 240 square miles of Hamilton County of Ohio, as well as the nine surrounding counties in the Greater Cincinnati area.
