How to Vet an Air Ambulance Operator — A Due Diligence Checklist

Air ambulance is one of the few purchases people make under maximum stress, minimum time and near-total information asymmetry. A family in the middle of a crisis is asked to wire a five- or six-figure sum to a company they found ten minutes earlier, on the basis of a website that looks professional. The market contains excellent, rigorously accredited operators and it also contains websites with stock photography and no aircraft at all. This guide is a practical due diligence checklist that a family member, case manager or corporate risk officer can work through in under an hour.

We are a broker, not an operator, and we say that plainly — we arrange flights on aircraft operated by certificated third parties. That is a legitimate and common model, and much of this checklist applies to vetting brokers too. What matters is that the party you are dealing with is transparent about which role it plays, and that a properly certificated operator sits somewhere behind the transaction. Our own credentials, insurance and regulatory disclosures are published in full on our compliance pages, and our parent company's corporate information is at https://thelimitlesssky.com.

Step One — Establish Who Actually Operates the Aircraft

The first and most revealing question is: are you the operator of the aircraft, or a broker? There is nothing wrong with either answer, but there is a great deal wrong with an evasive one. An operator holds an Air Operator Certificate (AOC) issued by a civil aviation authority, or in the United States an FAA Part 135 certificate, and can quote its certificate number without hesitation. A broker arranges transport on operators' aircraft and, in the United States, is subject to specific disclosure duties under the Department of Transportation's air charter broker rules in 14 CFR Part 295.

Ask for the operating certificate number and the name on the certificate, then check it against the relevant authority's public register. In the US, FAA certificate holders are verifiable through the agency's databases. In Europe, national authorities publish AOC holder lists. If the company says it is a broker, ask which operator will fly your mission — you are entitled to know the identity of the actual carrier before departure, and in the US you are entitled to it by regulation.

A red flag worth taking seriously: a company that claims to own a large fleet but cannot produce registration marks. Aircraft registrations are public. If a provider lists twelve jets, you should be able to look up twelve tail numbers and find twelve aircraft registered to a company with a matching name. Marketing pages showing generic aircraft photographs with no registrations visible are worth a second look.

Step Two — Check Medical Accreditation

Aviation certification says an aircraft is safe to fly. It says nothing about the quality of medical care on board. That is the role of the two principal medical transport accreditation bodies: CAMTS, the Commission on Accreditation of Medical Transport Systems, which is dominant in North America and operates a global arm, and EURAMI, the European Aero-Medical Institute, which accredits providers across Europe, the Middle East and Asia. Both audit clinical governance, crew training and competency, equipment, infection control, quality management and adverse-event reporting.

Accreditation is voluntary and expensive, which is precisely why it is informative. An operator that has invested in and passed a CAMTS or EURAMI audit has submitted its clinical practice to external scrutiny. Both bodies publish searchable lists of currently accredited providers, so a claim of accreditation is verifiable in about ninety seconds. Check the expiry date as well as the existence of the entry; accreditation lapses.

Absence of accreditation is not automatically disqualifying — some competent regional operators serve markets where accreditation is uncommon — but it shifts the burden of proof. In that case ask what clinical governance framework the operator follows, who its medical director is, what that person's specialty and licence status are, and how clinical incidents are reviewed. A serious operator answers these questions readily. A reseller cannot answer them at all.

Step Three — Interrogate the Medical Crew and Equipment

Ask specifically who will be on board for your patient: how many clinicians, what their qualifications are, and what their aeromedical experience is. The baseline for an ICU transfer is a physician with intensive care or emergency medicine training plus a critical care flight nurse or paramedic. For a stable patient a nurse-only escort may be entirely appropriate. What you should never accept is vagueness — "a medical team will accompany the patient" tells you nothing.

Aeromedical experience matters independently of clinical seniority. A hospital intensivist who has never flown is not automatically prepared for the constraints of a pressurised cabin at altitude: reduced partial pressure of oxygen, gas expansion in body cavities and equipment, vibration, noise that makes auscultation impossible, limited space to manage an airway, and no possibility of calling for help. Ask how many missions the crew has flown and whether they hold a recognised transport qualification.

On equipment, ask for the specific items and their certification status. Medical devices used in flight should be certified for airborne use — typically to RTCA DO-160 standards for electromagnetic compatibility — and secured to airworthiness requirements. A credible answer names the transport ventilator, the monitor and defibrillator, the syringe drivers, the oxygen provisioning and the reserve calculation. Ask explicitly how much oxygen will be carried relative to the flight time, including diversion reserve, and confirm that infusion pumps and suction have independent power.

Step Four — Insurance, Liability and Contract Terms

There are three distinct insurance layers in a medical flight and you should confirm all three. Aircraft hull and passenger liability insurance is carried by the operator and covers the aviation risk. Medical malpractice or professional indemnity cover applies to the clinical care delivered by the crew. And where a broker is involved, professional liability cover applies to the arranging party. Ask for certificates and check the named insured, the policy limits and the expiry dates.

Read what the contract says about cancellation, delay and deterioration. Medical missions change: a patient can be declared unfit an hour before departure, a receiving hospital can lose the bed, weather can close an airport. What happens to your money in each case? Reasonable terms provide for a partial refund when the mission has not launched and a defined charge structure once the aircraft has positioned. Terms requiring full non-refundable prepayment with no cancellation provision at all are a commercial red flag.

Payment mechanics also deserve scrutiny. Legitimate operators and brokers invoice from the corporate entity named in the contract, with matching bank details in the country of registration. A request to pay a personal account, a third-country account with no connection to the company, or exclusively in cryptocurrency should stop the transaction until it is explained. In fraud cases this is almost always the point at which the deception could have been caught.

Step Five — Test the Operational Answer

The final test is not about documents at all. Describe your actual mission and listen carefully to the answer. A genuine operations desk will immediately ask about the patient's clinical condition, current oxygen requirement, ventilation status, infusions, weight, mobility, infection precautions, the sending hospital's location and the receiving hospital's acceptance. It will ask who the medical contact is at both ends. It will discuss runway length, permits, and whether the patient's condition tolerates a fuel stop.

A weak provider will ask only for the two cities and a credit card. The quality of the questions you are asked is the most reliable single indicator of the quality of the organisation you are speaking to, and it cannot be faked by a good website.

Ask also for a specific aircraft and its position. "A Learjet 45, tail number known, currently in Palma, positioning time two hours ten" is an answer from an organisation that has actually checked. "We have aircraft available worldwide" is an answer from an organisation that has not. Cross-checking operator claims against independent market data — fleet composition, base locations, typical utilisation — is straightforward using the open business-aviation database at https://thelimitlesssky.com/intelligence, and it takes minutes.

Finally, trust the pattern rather than any single item. One missing certificate might be an administrative lapse. Vague crew details, an unverifiable certificate, unusual payment instructions and a price far below the market together are not a lapse; they are a warning. In a genuine emergency you will not have time to run every check — which is the strongest argument for choosing your provider, or your broker, before you need one.
