The similarities are stunning. In your sighting, you can see blue, white and orange in the wing and tail, and it's all a good match for his plane. Even the blue tip of the real plane's wing matches the blue tip of your sighting.
Looks to me like you're looking at half a plane though and the rest is concealed by undergrowth. If you enable the terrain, you can see that it's half-way up a peak on the side of a valley. If you follow that valley North East, you will arrive at KZ ROSASCHI AIR PARK. In fact, the runway can be seen in the distance from the crash site.
