• Aircraft insurance policies are claims or lawsuits arising out of the ownership, maintenance, or use of aircraft that are generally excluded from standard commercial general liability (CGL) forms. Businesses choosing to use private jets in their operations should purchase specific insurance to cover the risk of loss of aircraft liability: aircraft liability insurance or liability for an individual non-owned aircraft, and possibly liability coverage for surplus aircraft. Third party liability coverage is often provided, which also includes hull (physical damage) coverage and medical payments. Rules for using aircraft are not standardized and vary widely. Some insurers offer policies that combine aircraft and hull liability with other aviation coverages such as aircraft product liability, airport liability, land-based general liability, and hangar owner liability coverage.
