SDCL § 21-63-9: Product not in compliance with mandatory government contract specification.

If the injury-causing aspect of the aviation product was not, at the time of manufacture, in compliance with a mandatory government contract specification relating to design, or if the specification related to warnings or instructions that were not in compliance with a mandatory government contract specification relating to warnings or instruction, no presumption exists and the burdens of proof applicable to nonaviation products liability actions apply.
