Aviation Insurance for Part 135: Requirements, Compliance, and How to Reduce Premiums

Under 14 CFR Part 205, all U.S. air carriers (including Part 135 operators) must maintain minimum levels of aircraft liability insurance. Coverage requirements vary based on aircraft size and operation type.

Most charter clients and brokers require significantly higher coverage than regulatory minimums. Typical coverage ranges from $10 million to $100 million in combined single limit liability depending on aircraft type and passenger count.

Third-party safety ratings (ARGUS, WYVERN, IS-BAO) directly influence underwriter risk assessments. Up to one-third of IS-BAO registered operators report measurable premium reductions after certification.

Insurers view safety ratings as evidence of operational maturity. An IS-BAO Stage III operator with a mature SMS presents a fundamentally different risk profile than an operator with no third-party validation.

Compare safety rating options in our ARGUS vs WYVERN vs IS-BAO guide to determine which provides the best ROI for your operation.

As the FAA SMS mandate approaches, insurers are already factoring SMS implementation into pricing models. Operators with documented SMS programs demonstrate proactive risk management that directly correlates with lower claim frequency.

Provide your underwriter with your SMS documentation, safety reporting data, and corrective action records during renewal negotiations. Quantifiable safety data is your strongest negotiating tool.

An insurance lapse is an immediate grounding event. You cannot conduct Part 135 operations without valid insurance coverage. If a lapse occurs, your certificate authority is effectively suspended until coverage is restored.

Set renewal alerts 90 days before expiration and maintain backup contact information for your broker and underwriter. Track insurance expiration alongside your other compliance deadlines in Navlyt Compliance.
