Trim Tab Actuator

Stronger metals and longer lasting coatings for increased service life!

  • Save hundreds $$$
  • Black Max™ coated stainless screw for wear and corrosion resistance 
  • Aluminum/bronze inner barrel prevents sub-zero lockup
  • Anodized sprocket resists chain wear
    • Save hundreds $$$ with PMA repair parts for your actuator

McFarlane has developed a direct replacement trim tab actuator that incorporates many design improvements. Longer lasting coatings are utilized for increased service life, smoother operation, and improved corrosion resistance.

The Trim Tab Actuator is manufactured with high strength stainless steel alloy that has been nitrocarburized for maximum wear, low friction, and smoother thread operation than the OEM part. The sprocket is made from stronger aluminum, then anodized for wear and corrosion protection. The known problems of original parts have been addressed and resolved with McFarlane’s new design!


We now offer new FAA-PMA assemblies, replacement components, and services for your Trim Tab Actuator!

Buy new or send yours in for service or repair.
