Two blades if memory serves. Tricky to see though, as the lower nose is rammed into the seabed.

Okay, I’m getting more and more convinced that this is a Rangemaster. On examining the photos closer I think I can make out the profile of the two nose lights just below the air intake apertures on the cowling. They’re almost completely buried in the rocks, but I think that is what they are. Clearest is on the bottom right image.

Thanks, best fit yet! I think it looks most like this model – G I0520 (it has a division between the front windscreens, which some seem to lack.)

Only reservations are – size of the first windows on either side seem a bit larger than on the wreck pictures (it could just be foreshortening perspective through the water though.) The door profile certainly fit the bill. I have pinged the pictures off to http://www.navionx.org Maybe they can give me a model/year. How would I go about getting an accident report from Greece I wonder?

Thanks TonyT, it does look much more like the Pa32-60 or Saratoga than anything else I have seen. Door is definitely on the left though…. I snorkelled around it and can confirm that the images are not flipped. I reckon even with the cockpit roof crushed down a bit – that couldn’t really explain the differences between the window division shapes. The front windscreen panel shapes do come to a kind of point at the bottom outside corner, and window divider elements are fairly wide too.
True, I have become obsessive about identifying this aircraft – and it is driving me nuts.
A proper Mystery.
