There is only one standard “All-Risk” cover for Air transits (excluding sending by posts). The insurance covers all risk of loss or damage to the subject matter insured except as excluded. If an insurer would like to restrict the cover he can do so by attaching ICC(Air) clause as well a manuscript wording on the schedule of the policy restricting cover such as TLO which would mean Total Loss only. Exclusions are similar to the ones under ICC- A. Duration clause is also similar to that under ICC – A, B or C except that the cover would terminate on the earliest of the various alternatives spelt out under clause 5, one of which is “on the expiry of 30 days after unloading the subject matter insured from the aircraft at the final place of discharge.”
