Two certificated flight instructors in Texas — one holding a CFII rating and the other an MEI — are exploring a co-ownership model in which a jointly purchased aircraft would serve multiple simultaneous roles: personal flight time building, revenue-generating flight instruction, and potential dry or wet lease arrangements with a local flight club. The post surfaces on r/flying and reflects a common inflection point for early-career instructors who are trying to leverage aircraft ownership as both a professional tool and a tax-advantaged business asset. The authors acknowledge they have no prior ownership experience but are aware of the total cost of ownership, which positions them ahead of many first-time buyers in terms of baseline expectations.
The financial and regulatory architecture of this type of arrangement is considerably more complex than the post implies. Operating a for-profit flight instruction business using a personally owned aircraft requires careful coordination with IRS rules around Schedule C or LLC business deductions, FAA regulations under 14 CFR Part 61 and potentially Part 141 or Part 135 if rental is formalized, and state-level business licensing in Texas. The write-off question depends heavily on how the aircraft is actually used: the IRS requires that any business use be ordinary, necessary, and well-documented, and the agency scrutinizes aviation deductions aggressively. Mixed personal-business use triggers depreciation proration and can expose both owners to passive activity loss limitations under IRC Section 469 if the instruction activity does not qualify as an active trade or business. Co-ownership itself adds another layer — a formal partnership or LLC agreement is essential to define liability, usage priority, maintenance cost sharing, and exit provisions, all of which become critical if the business relationship deteriorates.
The flight club sublease concept, while operationally attractive, introduces FAA dry-lease versus wet-lease distinctions that carry significant compliance implications. If either owner acts as pilot-in-command during compensated instruction flights in the aircraft, that operation could be characterized as a wet lease and potentially require Part 135 certification, depending on the specific structure and compensation arrangement. Aircraft offered to a club for member rental without an instructor aboard generally qualifies as a dry lease, which is permissible under Part 91 if structured correctly, but the club would need to establish its own renter qualification standards, insurance minimums, and operational control documentation. Insurance underwriters also treat club-use aircraft very differently from owner-operated aircraft, and premiums can increase substantially when the aircraft is made available to a rotating pool of pilots with varying experience levels.
From a broader industry perspective, this arrangement reflects a persistent structural challenge in general aviation: the path from CFI certificate to meaningful career hours remains expensive, and co-ownership or leaseback programs are among the few mechanisms that allow early-career instructors to offset that cost. Flight school leaseback programs — where an owner places an aircraft with an established Part 141 or Part 61 school in exchange for revenue sharing and reduced operating costs — represent the most institutionalized version of this model and typically offer cleaner regulatory footing than ad hoc club arrangements. The leaseback market has tightened in recent years as training demand has surged post-pandemic and schools have prioritized retaining their own fleets, which has simultaneously made owner-supplied aircraft more attractive to schools and increased scrutiny of informal arrangements that blur the line between private operation and commercial air carrier activity. Pilots considering this path should consult both an aviation attorney and an accountant with specific experience in aircraft business taxation before committing capital to any purchase structure.
