Gull Wing Biplane

While traveling along the west coast in 1994 I stopped at the Tillamook Naval Air Station Museum, in Tilamook, Oregon.  I took a picture of this unusual biplane.

I was first able to identify this aircraft from the book This Was Air Travel, by Henry R. Palmer, Jr.  (copyrighted 1960 & 1962).  There are two photos in This Was Air Travel of Aircruisers operated by the New York And Suburban Airlines.  The windows and engine cowling on these photos lead me to believe that they are photos of the Bellanca Airbus.

Joseph P. Juptner's U.S. Civil Aircraft Volume 4 has details on the Bellanca Airbus. 

Two different CAA aircraft type certificates were issued for the Bellanca Airbus P-100 (ATC 360) and P-200 (ATC 391).  The major difference was engine type.  The P-100 model was powered by a 600 hp, 12 cylinder v-type liquid cooled Curtis Conqueror engine.  The P-200 models were typically equipped with either a 650 hp Wright Cyclone or a 650 hp Pratt & Whitney Hornet.   The first P-200 model used a 575 hp Wright Cyclone, its performance was less than the earlier P-100 model.   The radial engines of the P-200 models have a very short engine cowling covering just the engine cylinders.  Both P-100's and P-200's had rectangular passenger windows.  

US Army Air Corps also acquired several Bellanca Airbus's. The first two were designated YIC-27, and 12 more were designated C-27's.

U.S. Civil Aircraft Volume 6 covers the Bellanca Aircruiser (ATC 563).   The Aircruiser was refined and enlarged Airbus.  Three different Wright Cyclone engines were used starting at 675, 760, and 850 hp.  The Aircruisers were used mostly in Canada because of U.S. restrictions on large single engine transport aircraft in airline service.

The Bellanca Aircruiser I saw at the Tillamook Naval Air Station Museum was registered as CF-BTW.  This is also the same registratio number listed in USCA V6.   Google found these two photos of the same Aircruiser on floats. (#1 &  #2)  Entering Aircruiser in the Search Aircraft Model here at Airport-Data.com lead me to N2191K. It's is registered to the Erickson Group Ltd, in Beaverton, OR.
