48 C.F.R. § 3028.306-90
(b) For the U.S. Coast Guard, the contracting officer shall insert the clause at (HSAR) 48 CFR 3052.228-91, Loss of or Damage to Leased Aircraft, in any contract for the lease of aircraft, except in the following circumstances:
(d) 49 U.S.C. 44112, as amended, provides that no lessor of an aircraft under a bona fide lease of 30 days or more shall be liable by reason of his interest as lessor or title-holder of the aircraft for any injury to or death of persons, or damage to or loss of property, unless such aircraft is in the actual possession or control of such person at the time of such injury, death, damage or loss. On short-term or intermittent-use leases, however, the owner may be liable for damage caused by operation of the aircraft. It is usual for the aircraft owner to retain insurance covering this liability during the term of such lease. Such insurance can, often for little or no increase in premium, be made to cover the Government's exposure to liability as well. In order to take advantage of this coverage, the Risks and Indemnities clause at (HSAR) 48 CFR 3052.228-93 prescribed in paragraph (d)(1) of this section shall be used.
