Marking on the bracket .

Looks like a part from the engine.

Smashed heat exchanger.

Didn't know what this was.

Close by found a piece of another one with a name plate. Looks like it was a Navy aircraft.

Piece with a latch on it.

This piece caught my eye.

Taking a closer look, I saw the number 710 LH writen on it with pencil. It was under the paint which chipped off in the crash. It must have been put on during the aircraft's assembly. Thinking that the LH stands for lefthand and the 710 the last digits of the serial or construction number. Just guessing, but in the past, I was able to figure out another aircraft's ID using a numer like this. The only A4D-2 serial number ending in 710 is BuNo 142710, looking into it.

Another part from the engine.

This looks like it was a filter, it's filtering element is missing.
