Good luck! Hope you get those pics.

Thanks for all the information given here.The fishermen invited me to go out to the site at low tide to snorkle and take a few pics.There is more then one plane in this area.The pieces are very large and to big to bring in.They do not want it disturbed because it is being used by red snapper as their home.Wish me luck and maybe i will get the pics

Anon, Farallon, Panama is a long way from the US. Mainland. The Rio Hato Airport near Farallon is on the coast and was built by the US Armed Forces in 1942. It was then Rio Hato Army Air Base with the United States Army Air Forces Sixth Air Force based there. From what I can find, the Sixth Air Force were using the P-36 Hawk in defense of the Panama Canal. At that time they were using the Curtiss Electric constant speed propeller. Later versions were equipped with the Hamilton Standard Hydromatic Prop. I’d say now that you are looking at a Curtiss Electric constant speed propeller from a P-36 that ditched short of the runway in the ocean or lost power on take off. YMMV

Not saying this is the aircraft but this shows that they were used in Rio Hato, Panama.

F4U Corsair?

No, wrong engine.

The propeller (long blade CE) combined with a P&W R-1830 Twin Wasp reduction gear narrows the list of possibilities considerably.

Curtiss P-36 Hawk is a possibility but the ones that were used in S. America were the Wright Cyclone-powered variant, not Twin Wasp.

How far from the US mainland is the area in which it was found? It could be a USAAC machine. These, however, had the short bladed prop.:confused:

Anon.

F4U ??

Any chance that is from an F4U, AU-1 Corsair

Assuming the aircraft it was attached to was moving forward at the time, if all three blades are bent forward it means that the engine was under power at the time. The prop tips can’t compress the solid surface they hit and tend to “climb” up their own pitch as a result.

And yes, water if hard and fast enough doesn’t compress and can feel as hard as concrete. As anyone who’s landed in it from a great height.

Looking at the bends in the prop blades is leaving me puzzled.The prop was found in the ocean.If the plane crashed in nose first would the bends in the prop be pointing back towards the plane after making contact with the water? Maybe somebody here can explain what happened here.

what do i have here

Thanks for all the information on my propeller.I am going to pressure wash the gearbox and try to find some numbers to publish here.I am going to try and find out the name of the plane,its year,pilots name,and what caused this plane to end up in the sea.By the way i spoke to the fisherman again and he says there are more props in the area.One is smaller diameter and one is quite large.He says helicopter maybe.Will keep everybody posted.:)

Just checked and Farallon, where this was brought ashore, and Rio Hato, base of the 24th, are only 8km apart.

The prop (long blade CE) and engine combo only realistically gives P-36 in that region, and the 24th ‘s P-36A’s were very local, suffering numerous training accidents, (last bit from Wiki). Hope this helps.

P-36, 24th FS, Rio Hato Panama?

Think that list can be pruned by theatre – and weren’t some of those more normally associated with Hamiltons (DC3, etc)?

Well, off the top of my head, for P+W you would be looking at perhaps…..

Prop

P&W reduction gear means Twin Wasp with this (Curtiss Electric) prop. Didn’t some Hudson’s have this combination?

It appears to have the longer blades so I think Wildcat is out.

Anon.

So.. P-36, Wildcat, um.. Beaufort.. what have I missed?

Curtiss electric propeller attached to P&w twin Wasp reduction gear.

Is it not RH rotation?

Blenheim DH prop is just a Hamilton Standard really, and there are lots of US aircraft that used ’em.. but not convinced it is Ham Stand / De havilland from the hub.

Edit – on a second look, it looks Curtiss to me. Pic here – I have included an inset of the control mechanism – you can see it in one of the pics, tucked just behind the hub.

Not convinced Blenheims or Wellingtons were particularly thick on the ground in Panama

Moggy

Blenhiem or Wellington I would say.
