Between the left wing root & the left pack inlet?

Part has been identified as part of the Rolls Royce engine nacelle. Most likely the left engine.
shame this crucial part of evidence is still not recovered from the crash site. Photo was taken at Feb 23 2015!
Dutch Safety Board says it was too dangerous to recover debris in the north-westerly part of crash site due to fighting between Kiev and separatists.
Now separatists control area it is safe to enter (for photographer at least)
