LEARN MORE ABOUT WHO WE ARE

About Us


Engine Management Specialist (EMS) has been an industry leading expert on Pratt & Whitney turbo engines since 2003. This includes turbo-fan, prop, and shaft engines. Our personnel have decades of hands-on and management experience with these engines and allows us to provide a holistic, comprehensive array of services to meet customer key engine needs. We do not perform normal day-to-day maintenance, but manage major turbo-engine events for customers such as Overhaul (OH), Hot Section Inspection (HSI), and major repairs. To complement our management services, we offer detailed engine borescope inspections/reviews, reduce-to-spares (RTS) and parts reselling, as well as engine exchanges and outside brokerage sales of turbo engines and aircraft.

Major engine events are not routine and are significant in regards to engine and aircraft ownership. During these major events, some customers depend on the engine facility from the beginning to end for cost estimates and advice. For our customers, we perform the interaction and coordination with the engine facilities to obtain quotes and understand the options for a specific customer and their operations. We represent the customer’s interests and ensure that their investment is maximized and results in a safe and better product.

EMS works directly with the engine owner or designated representative such as chief pilot, director of maintenance (DOM), executive manager, contracted local operator, or fixed base operation (FBO). We obtain the pertinent project information such as quotes, engine condition, bulletins and tendencies for review with these individuals to discuss expectations and options. Our goal - to “arm” the customer with Pratt & Whitney engine knowledge to help them make informed decisions.


EMS has established a trusting relationship with their customers. A core portion of our business is from repeat customers.

The EMS Story

There is no substitute for the type of experience that led to the establishment of Engine Management Specialist, LLC.  Mr. Tim Critchfield,  owner and  president of EMS, began his aircraft engine career in 1985 with the United States Air Force (USAF). As a jet engine mechanic, Tim performed Pratt & Whitney turbo-engine assembly, disassembly, and testing on fighter jets. His excellence in the trade earned him “Maintenance Professional of the Year” as well as the USAF “95 Club” recognition. Upon completion of his service in the USAF, Tim worked for Pratt & Whitney Engine Services (PWES) West Virginia  in various positions including engine technician, detail inspector, and test cell operator. This experience led Tim to customer service positions, eventually becoming the PWES WV Manager of Customer Service for all turbo-engine product lines.

EMS works with all engine facilities to compete and represent the customer’s best interest. Although our company is local to the PWES WV engine facility, we work with all FAA approved shops including Pratt & Whitney, Designated Overhaul Facilities (DOF), non-DOF facilities, and other FAA approved facilities.  Facility selection is based on factors such as the engine model, event requirements, and customer considerations and/or criteria. This allows us to have a successful and customer-productive relationship with all engine facilities and positions EMS to:

•  Work closely with any facility to have the best resulting product for the customer;
•  Provide a significant amount of Overhaul/Hot Section Inspection engine work to major  engine facilities and develop positive, trusting business relations;
•  Travel to any engine facility and perform on-site detail inspection of engine parts;
•  Coordinate with the engine facility during all stages of engine rebuild to manage expectations;
•  Understand and work under engine maintenance programs on the customer’s behalf to maximize their program investments regardless of whether it’s an Eagle Service Plan, Jet Support Services, Pro Parts Plus, etc;
•  Negotiate warranties and insurance claims as an established expert;
•  Provide a significant industry outreach to market and resell customer RTS parts.

Our dedication to our customers and the turbo-engine craft has positioned us to grow from a single desk to more than 16,000 square foot facility as well as being recognized as a top-tier RTS facility. This is due to our positive customer feedback, the trusted relationships we have built with our customers, and our hard work returning positive results. We are the only third-party facility that provides RTS services for both PW300 and PW500 turbo engines. Our personnel have extensive and qualified turbo-engine experience allowing us to provide multiple services for the customer that encompass all options and decisions in regards to turbo-engine ownership and service.


EMS employees aspire to provide high-level customer service  on a daily basis, and expect the same from its service providers.
