Cabin Environment Controls for Cessna and Piper Aircraft  
Longer life and improved design

• Special, heavier wire for more fatigue strength and reliability
• Improved friction mechanism
• Reduced vibration wear
• High temperature Teflon lined conduit 

Controls for Cessna Aircraft 

McFarlane has FAA-PMA approval on the cabin air, cabin heat, cabin vent, cold air and defrost controls for many single engine Cessna aircraft. All of these controls feature McFarlane's improved push-to-unlock mechanism with greater holding strength and longer life. Most knobs match originally equipped knobs.

Controls for Piper Aircraft

McFarlane has FAA-PMA approval on the carburetor heat, alternate air, fuel mixture, parking brake, and cabin environment controls for most single engine Piper aircraft. Our anti-rotate feature reduces stress on the inner wire.  

Give your panel an upgrade - Replace old discolored knobs!

High quality replacement knobs duplicate the original Piper color and shape to maintain the original factory appearance of the instrument panel. To select the correct knob for your aircraft, please see the Eligibility Chart.
