Why might I need to change out or upgrade my aircraft propeller? Obviously if your propeller is damaged or unserviceable, you will need to change your propeller.  Other reasons to consider an upgrade include:

  - To Improve take off and climb

 - To make your airplane quieter

 - To gain ground clearance

 - If you go from wheels to floats or visa versa

 - If you change your flying habits (ie used to fly from grass strip to cross country)

 - Move from sea level to a high elevation city

- Part 135 FAA requires change out of aircraft propellers as prescribed by the manufacturer after so many hours of use
