Reading a charter operator's insurance certificate.

A Certificate of Insurance summarizes that coverage exists; it doesn't on its own prove every term, exclusion, or condition of a policy. For a family office, its value lies in confirming that the evidence lines up exactly with the operator, aircraft, date, and operation being contracted.

The fields that matter

### Insured party The insured has to be the direct air carrier operating the flight, not just the owner, manager, broker, or a related brand. If several entities appear, ask for an explanation of the relationship and who holds operational control.

### Aircraft Check the tail number and the manufacturer, model, or fleet schedule listed. The tail number on the COI has to match the aircraft actually offered. If the operator relies on blanket coverage or class-based coverage, the broker should explain how that specific aircraft is confirmed as included.

### Validity The effective date has to cover the flight. Also confirm there's no cancellation, exclusion, or later endorsement in effect. The FAA requires that evidence filed by carriers stay accurate at all times, and that aircraft or class changes are added through endorsements within the applicable regulatory window.

### Limits Don't treat a single number as the whole picture. Review the combined single limit, passenger liability, property damage, war-risk coverage where relevant, and any sublimits or conditions. NBAA recommends confirming that coverage is adequate, that limits exceed DOT minimums where appropriate, and whether the client can be named as additional insured.

### Additional insured and waivers Additional insured isn't the same as loss payee, certificate holder, or additional interest. A waiver of subrogation doesn't turn the client into an insured party either. These terms should go through counsel or a risk adviser, particularly if the family office carries its own contractual requirements.

What the COI doesn't prove

The COI doesn't confirm that the pilot is qualified, that the aircraft is on the D085, that the operator's audit is current, or that the flight runs under the right authority. It also doesn't necessarily reveal every exclusion, warranty, deductible, or notice condition.

For U.S. air carriers subject to Part 205, the FAA requires evidence of aircraft accident liability insurance, filed on OST Form 6410; certain foreign air carriers use OST Form 6411 instead. The specific obligations depend on the operation and the carrier's status.

A working review process

1. Match the legal name on the COI against the contract. 2. Match the tail number against the aircraft offered. 3. Confirm the effective date and issue date. 4. Ask for endorsements if the aircraft was added recently. 5. Confirm limits, jurisdiction, passenger count, and charter use. 6. Verify the certificate independently with the insurance broker or underwriter directly. 7. File the version received, along with any later change of aircraft.

A legitimate operator may need time to produce an updated COI. That's preferable to receiving a generic document that doesn't identify the flight. If the entity selling the service can't explain who's insured or which aircraft is covered, the decision should pause.
