Cabin Environment Controls for Cessna Aircraft
Longer life and improved design
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 orginally equipped knobs.
