Model: Navion, Temco Twin D16-A Registration: N123N
Year: 1947 Serial Number: TTN-56
Engine(s): Lycoming O-340-A1A, 4-Cyl., 170-Hp each Owner: Dennis W. Susens, Highland, MI
Location: VBW, Bridgewater Airpark, Bridgewater, VA Photographer: Ken Stoltzfus
Date: November, 2003 Present Registration: Same Present Owner (FAA info): Same
Notes: 12/15/04 - N123N was built as a 1947 North American Navion, s/n NAV4-206, NC8528H (which would soon become N8528H).

The first Airworthiness document in the FAA records is the January, 1947 Statement of Conformity by North American Aviation, Inc., for Navion, s/n NAV-4-206. The original Operations Limitations say, "This airplane is approved for: INSTRUMENT NIGHT - Not for night hire beyond a 3-mile radius from the center of the airport of take off." Interesting!

There were at least two Twin Navion conversions. In addition to the Temco-Riley there was the Camair, with Continental O-470 engines. I don't have any Camair photos yet.

In April 1955 it was sold to Temco Aircraft, of Dallas, TX, who converted it to a Temco D-16A, s/n TTN-56, under Type Certificate 2A-1. Several persons mistakenly called it a Ryan Navion instead of a North American Navion, including Temco.

Notes: N8528H had 2750-hours TT before conversion and a change of registration to N123N. The twin Navion uses the Lycoming O-340-A1A engine, a model Lycoming unsuccessfully tried to insert between the '320 and '360 series engines.

Somebody somewhere added tip tanks to N123N.
