Crash of plane P-39 Airacobra
 

I am looking for information about crash site of plane P-39 Airacobra, which was shot down on 05.05.1943 near the village of Krimskaya (Krasnodar region) in an air battle.This aircraft was shot down by Pilot 8./JG52 Hptm. Gunther Rall on 05.05.1943 at 12 : 9 o'clock in 85113 according to the coordinate system of the Air Force (Pl.Qu.). To detect the crash site, one must check pilot application, which even Gunter Rall has written after the air battle.
Is there any information? Or where can you look for them?
Many Thanks,
Igor
