Contract mechanics
The fractional jet ownership contract
A fractional jet ownership contract is three agreements and an acknowledgment: the purchase agreement, the aircraft management agreement, the dry-lease exchange agreement and the operational control acknowledgment. Between them they decide what you pay every month of the term, which aircraft you can fly and at what notice, what you answer for on your own flights and what the program pays back when you leave.
Fractional Aviation Advisors reads those agreements for the buyer and no one else. Our principals are former senior NetJets executives who sold and oversaw these programs from the inside, and we take no operator commissions or referral fees. Before you sign, we read the term, access, cost and exit provisions against your expected travel and estimate the cost of ownership and the likely proceeds at exit.
What the agreements decide
The proposal states the price; the agreements decide what it buys
A proposal presents a few headline figures: the purchase price, the monthly fee, the occupied hourly rate and the hours. The agreements determine what those figures mean over the term. The purchase agreement conveys the interest and usually carries the repurchase provision. The management agreement sets the monthly fee, the occupied hourly rate, the fuel adjustment and how each escalates. The exchange agreement sets which aircraft you can fly and the ratio at which hours convert on a different type, and the acknowledgment records what you answer for on your own flights.
In our reading, three questions decide whether a proposal is as good as it looks: what the fee and the hourly rate will be in the final year of the term after escalation, whether the notice and peak-day terms leave your recurring dates inside the program's guarantee, and what the repurchase formula returns on the day you leave. None of the three appears on the proposal's first page, and each is far easier to settle before signing than to change afterwards. The valuation timing and the renewal notice can fall before expiration, so the dates in the agreement matter as much as the figures.
What you pay
The management agreement sets the cost of every month of the term
The management agreement appoints the program manager to crew, maintain, schedule, hangar and insure the aircraft on the owners' behalf, and it sets what you pay for that: the monthly management fee, the occupied hourly rate, the fuel adjustment and the way each of them escalates. Most of the lines on an owner's monthly statement trace to this document. The fee is charged every month whether or not you fly, so its escalation clause decides the cost of the later years, and we build it out year by year rather than reading the first-year figure.
The purchase agreement conveys the fractional interest in a specific aircraft, identified by registration number, and records the price, the closing date and the size of the interest. Federal rules set a minimum share size, explained in fractional jet ownership requirements; the hours and charges attached to that interest are program terms rather than rules.
In a fractional program the management agreement runs with the ownership interest, so it ends when the interest is conveyed, subject to the notice, consent and sequence the agreements require. A whole-aircraft management agreement is a separate contract with its own termination provision for your counsel to review.
What you can fly
The exchange agreement and the access terms decide whether the hours are usable
The dry-lease exchange agreement makes the program aircraft available to each owner as needed and without crew. It is the reason you fly whichever aircraft is positioned for the trip rather than the one your interest is held in. It also defines interchange, the use of a different aircraft type, with a ratio at which hours convert: an hour on a larger cabin draws down more than an hour of allocation, and an hour on a smaller one draws down less. The program can usually change the ratio on notice, so the schedule in force is the one that counts, not the one in the proposal.
Substitution is the program's right to provide a different aircraft from the one requested, usually of equal or larger cabin at the contracted rate, and your obligation to accept it. The agreement governs smaller-aircraft substitutions, the replacement service promised when an aircraft goes out of service and whether charter aircraft may be substituted.
The allocation is stated per share year, and a one-sixteenth interest is commonly paired with 50 occupied hours, the hours flown on your trips. That pairing is the program's convention, not a rule. The agreement sets how unused hours are treated at year end, whether hours can be borrowed from the next year, the rate for additional hours, and who may fly on the allocation without you aboard and at what notice.
Notice is the number of hours before departure at which the program guarantees an aircraft. The program designates peak days, the high-demand dates it names each year, and the agreement sets how many there are, the notice they carry, whether a surcharge applies and how much departure flexibility the program may require on them. An allocation that covers the year's hours can still leave you without an aircraft on the dates that matter if the peak-day and notice terms put those trips outside the guarantee, which is why we read these terms against your recurring dates before we read the price.
How you leave
Repurchase, renewal and early exit are agreed at signing, not at the end
The repurchase provision establishes your right to sell the interest back and the valuation method the program applies; selling a fractional share explains how proceeds, deductions and continuing fees affect what you receive. Flexjet describes a sale back at contract end, and NetJets describes a liquidity commitment. A contractual buyer does not establish a guaranteed recovery amount; the provision's conditions and valuation method determine the commercial result, so we model a range of exit values rather than the purchase price.
The agreement defines the commitment and the election deadlines, with the end-of-term mechanics explained in fractional share renewal. Early termination is priced as a percentage of the remaining commitment or as a repurchase at a less favorable formula than the end-of-term one, and some agreements bar it in the first years. A later change in your travel does not itself create a right to leave, so the cost of each permitted route out is part of the price you are agreeing to.
A sale to another owner follows the consent and first-refusal provisions explained in fractional share transfers. If the program manager is sold or changes control, the assignment clause sets what happens to the agreements and whether your consent is required.

Discuss your agreementWhat you answer for
The operational control acknowledgment is prescribed, not negotiated
Under the federal rules for fractional programs, you are in operational control of a program flight carrying passengers or property you designated, and you and the program manager are jointly and individually responsible for compliance. On that flight the program manager provides management services, not carriage, and is not a direct air carrier. A charter flight, including one substituted for a program aircraft, puts the certificate holder in operational control instead.
The program manager briefs each owner on those responsibilities when the management agreement is signed, and again at renewal or extension, and you sign an acknowledgment. It sets out when you are in operational control and who answers for compliance with the management specifications, the FAA-issued document that authorizes the fractional program, and it records the enforcement exposure and the liability risk in a flight-related occurrence.
Its content is prescribed rather than negotiated, so the work is understanding what you are acknowledging. We send it to your counsel and insurance advisor while the terms are still open, so they can consider the legal responsibilities and insurance implications before closing.
What we read for a client
How the terms change the cost and usefulness of your share
Access rules can limit the usefulness of an hour allocation, and fee increases or a loss at exit can offset a low hourly rate. We read the commercial terms of each agreement against your travel and your expected holding period and put a figure on the term as a whole: the capital, the escalating fees, the flight charges on your actual trips and a range of exit proceeds under the repurchase formula.
The operating provisions rarely change, because the exchange depends on common terms for all owners. Negotiation generally concerns the commercial schedule: price, hours, term and the interchange ratio applied to your interest. We identify the points worth raising with the provider without assuming that any provision will change, and we say which of them are worth the conversation.
Legal effect, enforceability and liability belong with your counsel; operational-control exposure also warrants insurance advice, and tax questions belong with your tax advisor. Scope and fee are agreed before an engagement begins, and we take no operator commissions or referral fees.
