What Can We Do For You?


New Propellers

We keep a rotating stock of fixed-pitch propellers and constant speed propeller blades in our extensive inventory.  If we don't have the item you need, we are happy to assist you in locating and shipping your new propeller.

Re-Pitch & Repaint

Not getting the performance you desire from your fixed-pitch propeller?  We can re-pitch your prop to create better climbing or cruising performance, as your needs dictate.  And every re-pitch receives a fresh coat of paint before we return it to you!

Hartzell Composite Certified

Composite material blades are a remarkable technological innovation used in many high-end aircraft propellers and turbines.  They reduce weight load to help increase fuel efficiency and engine performance while maintaining a longer average operational life over traditional aluminum blades.  Not all shops have the expertise or equipment to work on these top-tier products.  We have been certified by Hartzell to work on their composite material blades and turbines. Don't send your high-end composites to just anyone! We are qualified and prepared to handle your needs!

Propeller Overhaul

Moisture, debris, normal wear and tear—or the unfortunate prop strike—can do a number on your propeller.  Regular inspections and proper maintenance can significantly extend your propeller's life, saving you money in the long-run. Our skilled technicians will refurbish your propeller to like-new conditions, overhaul the blades and hub, replace parts as necessary, and give it a fresh coat of paint. All overhauls adhere to FAA and manufacturer specifications.

Propeller Repairs & Reseals

We can reseal or repair your propeller or hub on an as-needed basis.  From simply replacing worn-out seals to conducting a complete tear-down of your prop, we will diagnose all safety and performance issues and advise you on the best course of action.  Our top priorities are your safety, extending the life of your propeller, and providing the best solution for your situation.

AD Inspection

Keep up to date on your Airworthiness Directive (AD) and Eddy Current Inspection (ECI) requirements.  Whether you need a one-time inspection or have a recurring maintenance schedule, we are equipped to test the airworthiness of your propeller, blades, and hub. Safety and compliance are your top priorities—and our commitment to you!

Dynamic Balancing

Balancing your aircraft propeller increases the life of your engine, improves performance, reduces vibration and saves maintenance dollars. Our experienced technicians will generally reduce your propeller’s vibrations to half the acceptable .14 IPS limit. 
See our FAQ page for more info on when and why your prop should be dynamically balanced.
