I will try to find more later, but this one is not directly related. It is along the same lines of the subject at hand:
"In O'Connor v. Proprietors Insurance Co. the Colorado Supreme Court, affirming the decision of the Colorado Court of Appeals, held that when there is a provision in an insurance policy specifically excluding coverage in the event of an FAA violation, the insured is not entitled to recover unless it can be established that no causal relationship existed between the FAA violation and the accident giving rise to coverage. The policy in question provided no coverage for losses incurred if the aircraft was operated in violation of the terms of the Federal Aviation Airworthiness Certificate or Operational Record. Since the aircraft had not had its required annual inspection, the court found that the aircraft insurance policy did not cover damages sustained by the aircraft in the crash. The court held that the insured was not entitled to recover under the policy unless he could prove that no causal relation existed between the FAA violation and the accident and that the insured did not meet his burden of proof." citation: Recent Developments in Aviation Case Law, Rod D.
