policy Insures the amount an airline has at risk as a result of its hull policy deductible. Cover applies up to the deductible level, so it becomes an insurance of the actual deductible, subject to a small deductible itself. The intention is to cover ingestion damage to engines by foreign objects but it also covers damage to landing gear and fuselage. The policy follows the overlying hull ‘all risks’ cover subject to an annual aggregate limit.
