Cessna Bird Dog derivatives (Models 305, 308, 311, 312, 319, 321, 325)

[Sentinel Chicken]

Here's the Cessna 308:

Model 308-This design could be characterized as a four-place Model 305-the airplane which had become the U.S. Army's "Bird Dog" in 1950. The 308 was in answer to a military proposal which called for a new, larger aircraft category that was eventually filled by the de Havilland Beaver. Built on the general lines of the 170, the Model 308 had a much larger 47-ft wing span and 4,200 lb gross weight. Powered by a whopping 375 hp Lycoming GSO-580, it could operate smartly off unimproved strips and carry a 1,000-lb payload for 800 statute miles. Only one example was built, and it first flew in July 1951.

Hi,

the Cessna Model-311 was radical rethink of the L-19 featuring tandem
wing layout,the Model-312 was improved Bird Dog with major,but conventional
redesign of the wing.
Who has a drawings for them, I can't imagine what was the Model-311 ?.

Anyone ever seen a photo of a Model 330? ???

I have NEVER seen a picture of this elusive bird, nor of the Model 325... certainly the two most unknown types of all built Cessnas. Even the 327 has a picture circulating.

Hi Stéphane
Cessna 325 photo.
Sorry I cannot make scans at the moment (my machine room started a life of its own), but there is a picture of the Model 325 in "Wings of Cessna" by Edward H. Phillips, Page 64. According to the accompanying text four Model 325s were built (two in 1953 and two in 1956) and that this Cessna ag-plane model was largely based on the Model 305 (L-19).
Regards, Walter

Has anyone found a photo of a Cessna 325 over the years?

Here you go.
The picture is from „Wings of Cessna“ page 64, according to the book this is the prototype of the Cessna Model 325 with a hopper tank behind the front seat and sealed aft windows.

Engine is a Continental O-470 with 230 hp.

There's a reason all purpose-built Ag planes look the same. Hopper tank IN FRONT OF the cockpit, else the pilot is crushed when he crashes on takeoff.

Most, but not all.

And its development...

Not to forget the „famous“ Auster Agricola or the Rawdon T-1SD.

But perhaps the position of the hopper tank contributed to their failure.

Cessna 325, from the 1962 Cessna book An Eye to the Sky:



The first two Cessna 325 aircraft from 1953 were registered N1174D and N1175D (c/n 24000/24001).
The first of these went to Panama and was re-registered HP-255.
The second one's story seems more complicated; there exist two crash briefs for N1175D, the first one from 1965, where the aircraft is described as a TL-19D. Was it called so for lack of proper identification? Eight years later, a second crash occurs, also in Almyra, Arizona, but this time the aircraft is called a Model 305...
However, the more recent available data on the N1175D states that it was still flying in Arizona into the 21st century... Not bad for an aircraft that crashed twice!

Please note that the Cessna 319, despite being a Bird Dog derivative, is tackled in a separate topic, along with the Cessna 309, since both types were specifically used in Boundary Layer Control (BLC) research:

Although a substantially different aircraft than the L-1, the Cessna 321 (U.S. Marine Corps's OE-2) was later redesignated into the same tri-service series as the O-1C. And even if it 25 aircraft were produced, it remains a fairly little-known type.
