The single-engine P47 Thunderbolt went down on February 14 1945, just 10 weeks before the end of the war in Europe, at Ottersweier, in the southwestern state of Baden-Wuerttemberg.
Its wreckage was found four metres (15 feet) below ground in an orchard by Uwe Benkel, an amateur researcher in World War II crash sites, DPA said.
Its pilot was identified as Antoine Allard, 25, from Paris.
The location of the crash had long been known, and marked by a monument.

"Whenever I went by (the crash site) I always said a few words" to the ill-starred pilot, Doll said.
German soldiers placed a French flag and flowers on the site, to a crowd of several dozen onlookers.
Allard's remains will be interred at an as-yet unidentified cemetery, the report said.
