The German law on air accident investigation, the Flugunfall-Untersuchungs-Gesetz, says what an investigation is for. Section 3 says that it looks for the causes of an accident so that future accidents can be prevented. The same section then says what it is not for: Die Untersuchungen dienen nicht der Feststellung des Verschuldens, der Haftung oder von Ansprüchen. The investigations do not serve to establish fault, liability or claims.
