N.H. Rev. Stat. Ann. § 412-A:1

Every insurance company which issues insurance on hulls of aircraft, including their accessories and equipment, and liability resulting from the ownership, use or maintenance of aircraft shall file with the insurance commissioner for informational and auditing purposes a copy of the form of the policy containing the insurance contract covering such losses and all printed endorsements that may be attached thereto. As part of the audit process, the commissioner may disapprove any form if it contains a provision that does not comply with the requirements of law, is not in the public interest, is contrary to public policy, is inequitable, misleading, deceptive, or encourages misrepresentation of such policy.
