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 improved push-to-unlock mechanism with greater holding strength and longer life. Most knobs match originally equipped knobs.
- Special, heavier wire for more fatigue strength and reliability
- Improved push-to-unlock mechanism on MCS P/Ns = more holding strength
- Reduced vibration wear and longer life!
- High temperature Teflon lined conduit
