A commercial pilot certificate and a willing aircraft owner do not, by themselves, create a legal framework for compensated passenger carriage — a distinction that the regulatory structure under 14 CFR Parts 91, 119, and 135 makes abundantly clear. The scenario described in this post is one of the most commonly misunderstood areas of aviation law among lower-time commercial pilots: the line between operating legally as a paid contract pilot under Part 91 and conducting unregulated common carriage, which is a federal violation. The core legal concept at issue is "holding out" — if a pilot or operator in any way represents availability to transport persons or property for compensation to the general public, or even a selective portion of it, that activity constitutes common carriage and requires an FAA Air Carrier Certificate under Part 135. "Knowing a lot of people" who want to pay for flights is precisely the kind of informal holding out the FAA looks for, and the agency has a long enforcement history of pursuing exactly these arrangements regardless of how casually they were organized.
The LLC structure question is a persistent myth in general aviation circles. Placing an aircraft in an LLC does not insulate the operation from FAA scrutiny or reclassify what would otherwise be charter as something else. The FAA evaluates the substance of the operation, not its corporate wrapper. A contract pilot flying the aircraft owner and the owner's personally-invited guests on flights the owner directs — with no compensation changing hands from passengers to the pilot or the LLC — can be legally structured under Part 91, since the pilot is being compensated for their services by the owner, not for the carriage itself. However, the moment passengers are paying for transportation, even informally, the operation crosses into common carriage. There are narrow exceptions: Part 91.501 time-sharing agreements, interchange agreements, and joint ownership arrangements allow certain cost-sharing structures for large or turbine-powered multiengine aircraft, but these have strict requirements and do not apply to most light piston singles or twins that private owners typically operate.
Obtaining a Part 135 Air Carrier Certificate, administered under Part 119, is the legitimate pathway for the operation this pilot is describing, but it carries substantial barriers to entry that must be clearly understood before any business planning begins. A new Part 135 certificate requires the FAA to approve an operations manual, maintenance program, and operations specifications; designate a qualified Director of Operations, Chief Pilot, and Director of Maintenance; conduct conformity inspections on the aircraft; and validate that the proposed operation meets all currency, training, and dispatch requirements. The process routinely takes nine to eighteen months from initial application to issuance, and legal, consulting, and administrative costs generally range from $50,000 to well over $150,000 depending on the complexity of the operation and the number of aircraft. Ongoing compliance costs — required training, check rides, drug and alcohol testing programs, records maintenance — add significant annual overhead that a single-aircraft owner operating a piston single would likely find economically prohibitive relative to revenue potential.
The broader pattern here reflects a structural tension that is widespread in general aviation: aircraft ownership costs are high, utilization is low, and owners and pilots alike are constantly exploring ways to offset those costs through informal arrangements that ultimately run afoul of federal air carrier regulations. The FAA's Legal Interpretation database contains dozens of letters addressing exactly these scenarios, and the agency has consistently held that informality of the arrangement is not a defense. For a CFI who has spent two years building flight time and is now holding a commercial certificate, the most legally sound near-term path is to pursue employment with an established Part 135 operator or corporate flight department rather than attempt to self-construct a regulatory framework around a single-owner aircraft. Should the aircraft owner genuinely want to commercialize the operation long-term, engaging an aviation attorney specializing in air carrier certification — not the FAR/AIM — is the correct first step, not a regulatory interpretation exercise conducted via online forums.
