Many visitors to TwinNavion.com ask us about our experience with the Twin Navion. We've owned our D-16A since 1975. We rebuilt it, and a number of single engine Navions, and have maintained our Twin Navion since. Its safe to say that we've learned a lot.

The following comments have been prepared to help the prospective Twin Navion buyer, or a new owner, to learn from our experiences. Keep in mind that we're dealing with people's memories, and that we've had special arrangements with our mechanics, engineers and overhaul shops for decades. All of our maintenance has been carried out under the supervision of licensed mechanics.
