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 ever since. While we don't know everything, 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.

This is a list of Airworthiness Directives (ADs) issued against the Twin Navion series. These links connect directly to the FAA's website. However, this list does not include ADs that affect appliances (engines, propellers or avionics). The D-16, D-16A and Camair 480 are not immediately affected by ADs pertaining to the single Navion series, but there are some that have been issued that affect both singles and twins because they share common parts. 63-21-05 is a perfect example of this.

Find all your ADs on the FAA's website.

After a rash of gear collapses traced back to cracks in the nose gear fork, the Navioneers, who are the holders of the D-16/D-16A type certificate have issued a Field Service Bulletin for Twin Navions and single Navions based on an Aero Commander SB from 1958 (early Aero Commanders used Ryan nose gear assemblies). While its not applicable to the Camairs, owners of those planes should at least consider its incorporation. Click here to read.
