When your aircraft propeller needs maintenance, repairs, or a full overhaul, choosing a trusted service provider is essential.
The right propeller MRO partner can help minimize downtime, simplify maintenance costs, and, most importantly, keep your aircraft flying safely and reliably.
Whether you own a single aircraft, manage a flight school, or oversee a large fleet of piston or turbine aircraft, you have options through Hartzell Recommended Service Facilities or Hartzell Global Services.
While both provide quality propeller maintenance, repair, and overhaul services, there are distinct differences between the two. Let’s take a closer look at what sets them apart.

Hartzell Recommended Service Facilities (RSF) are independently-owned and operated propeller repair stations that Hartzell has verified for meeting our strict standards for servicing and maintaining Hartzell products. RSFs are endorsed by Hartzell to complete major repairs, warranty work, and full propeller overhauls.
Hartzell Propeller routinely audits each RSF to ensure it maintains the high quality standards expected of the Hartzell brand.

The Hartzell RSF network spans the globe, providing aircraft owners and operators with convenient access to quality service and support on nearly every continent.

Hartzell Global Services is a premier network of Hartzell-owned and factory-backed MRO facilities that service major aircraft propellers and governors as well as landing gear, wheels & brakes, and engine accessories.
HGS takes aircraft service and support to the next level by combining direct OEM expertise and factory resources with expanded MRO capabilities and standardized service programs to make aircraft maintenance more convenient and predictable at scale.
Hartzell Global Services is not limited to Hartzell-branded products. HGS facilities service multiple propeller brands, including Hartzell, McCauley, MT-Propeller, Sensenich, WhirlWind, and others, all with the same dedication to consistency and reliability.
Finding the right propeller service provider often comes down to your maintenance needs, location, and desired level of support.
Ultimately, both HGS and RSF networks share the common goal of helping aircraft owners and operators maintain their propellers to the highest standards of safety, quality, and performance.
