Private jet safetyratings explained
What a Part 135 certificate covers, what a third party audit adds, and the questions to ask before you fly.
Charter safety is not a single number. It is a certificate, an audit, a maintenance programme and two pilots, and the useful questions are specific.
The certificate is the floor, not the ceiling
In the United States, commercial charter is flown under FAR Part 135. That certificate sets minimum standards for maintenance, crew training, duty limits, operational control and record keeping, and the operator is inspected against them.
Part 135 is meaningfully stricter than Part 91, which governs private operation of your own aircraft. If somebody offers you a flight for money under Part 91, that is a serious problem and not a technicality. Ask for the certificate holder name and number, and ask which certificate the flight is being sold under.
What third party audits add
Independent auditors examine operators against standards that go beyond the regulatory minimum, covering safety management systems, pilot experience thresholds, training frequency, maintenance practice and emergency response planning.
An audit is not a guarantee and it does not replace the certificate. What it does is confirm that somebody outside the company has looked at the operation recently and in detail. For an operator you have no history with, that is worth a lot.
Ask which audits the operator holds, when they were last renewed, and whether the specific aircraft and crew fall inside the audited scope. That last part matters, because scope is not always the whole fleet.
Crew questions worth asking
Two pilots, always, for anything jet sized in commercial charter. Beyond that, ask about time in type rather than total hours. A pilot with twenty thousand hours and forty in this aircraft type is a different proposition to one with six thousand hours and two thousand in type.
Ask whether the crew is current for the specific airports on your itinerary. Terrain constrained fields require operator specific qualification, and this is a routine source of last minute aircraft changes at mountain airports.
Ask how the operator schedules against duty limits. An operation that routinely runs crews to the legal edge is telling you something about its culture.
The aircraft itself
Age alone is a weak signal. A well maintained twenty year old airframe on a rigorous programme is safer than a young one on a thin one. What you want to know is the maintenance programme it follows and whether it is manufacturer supported.
Get the tail number before you commit, not after. It lets you confirm the aircraft is the one you were quoted, and it is the thread that ties the operator, the audit scope and the maintenance record together.
Where brokers fit, and where they do not
A broker does not operate the aircraft and cannot inspect it. What a broker can do is refuse to present operators who do not meet a stated standard, and disclose the certificate, tail number and audit status of every bid so you can check them yourself.
Be wary of any broker who resists naming the operator before you commit. There is no legitimate reason for that. You are entering a contract with the certificate holder, and you are entitled to know who they are while you still have the option to decline.
A short checklist
Who holds the operating certificate, and what is the certificate number. What is the tail number and the year of manufacture. Which third party audits does the operator hold and when were they renewed. Is this aircraft and crew inside the audited scope. Is the crew qualified for every airport on the itinerary. What is the maintenance programme. Who is the operational controller for this flight.
Every one of those has a short factual answer. An operator who supplies them quickly is showing you how they run. An operator who does not has answered a different question.
Questions
Related answers
What is FAR Part 135?
The United States regulation governing commercial charter operations. It sets minimum standards for maintenance, crew training and duty, operational control and record keeping. Charter flown for money in the US must be under Part 135, not Part 91.
Do safety audits guarantee a safe flight?
No, and any broker implying otherwise is overselling. An audit confirms an independent party has examined the operation against a published standard recently. That is valuable evidence, not a guarantee.
Should I avoid older aircraft?
Not on age alone. The maintenance programme matters far more than the build year. Ask what programme the aircraft is on and whether it is manufacturer supported.
Will you tell me the operator before I book?
Yes. Every bid you see carries the operator name, certificate, tail number, year and audit status before you commit to anything. You are contracting with the certificate holder, so you should know who they are.
