8.196 FAILURE TO APPEAR OR SURRENDER—AFFIRMATIVE DEFENSE (18 U.S.C. § 3146(c))
It is a defense to a charge of failure to [appear] [surrender] if uncontrollable circumstances prevented the person from [appearing] [surrendering]. In order to establish this defense, the defendant must prove that the following elements are more probably true than not true:
First, uncontrollable circumstances prevented the defendant from [appearing] [surrendering];
Second, the defendant did not contribute to the creation of the circumstances in reckless disregard of the requirement to [appear] [surrender]; and
Third, the defendant [appeared] [surrendered] as soon as the uncontrollable circumstances ceased to exist.
If you find that each of these elements is more probably true than not true, you must find the defendant not guilty.
See United States v. Springer, 51 F.3d 861, 866-68 (9th Cir.1995) (discussing the "uncontrollable circumstances" prong).
