2.4 Commercial Air Operations & Operator Certification
Key Takeaways
- 14 CFR Part 119 defines the legal boundary between general aviation operations under Part 91 and commercial operations requiring air carrier or commercial operator certification under Part 121 or Part 135.
- Common carriage is legally established under AC 120-12A when an operator demonstrates: (1) holding out of a willingness to, (2) transport persons or property, (3) from place to place, (4) for compensation or hire.
- "Holding out" can occur directly through advertising, brochures, and websites, or indirectly through agents, word-of-mouth, or a general reputation of willingness to serve the public indiscriminately.
- Private carriage serves one or several selected customers without holding out; AC 120-12A notes operators with 18 to 24 contracts have been held to be common carriers.
- Under 14 CFR 119.1(e), student instruction, nonstop air tours within 25 statute miles under a 91.147 letter of authorization, ferry or training flights, and aerial work need no Part 119 certificate.
Commercial Air Operations & Operator Certification
A commercial pilot certificate authorizes an airman to fly for compensation or hire. However, holding a commercial certificate does not authorize a pilot to operate an air charter business, airline, or commercial air service. The operational boundary between private flying and commercial air transportation is governed by 14 CFR Part 119, which ground instructors must teach with legal precision.
The Part 119 Regulatory Framework: Pilot vs. Operator Certification
A critical distinction exists between pilot certification (regulated under 14 CFR Part 61) and operating certification (regulated under 14 CFR Part 119, Part 121, and Part 135):
- Part 61: Certifies that an individual pilot meets the technical aeronautical knowledge, flight proficiency, and experience standards to act as pilot in command of an aircraft for compensation or hire.
- Part 119: Establishes the certification and operational specifications for an entity (individual, partnership, or corporation) to act as an air carrier or commercial operator.
- Part 121: Regulates domestic, flag, and supplemental commercial air carriers (major scheduled passenger and cargo airlines).
- Part 135: Regulates commuter and on-demand charter operations (air taxis, corporate charter flights, nonscheduled air cargo).
Whenever a pilot provides both an aircraft and piloting services to transport persons or property from one place to another for money, that operation is legally presumed to be an air transportation service requiring an operating certificate under Part 119, unless an explicit exemption applies.
Common Carriage & the Doctrine of "Holding Out" (AC 120-12A)
Federal regulation of commercial aviation relies on the centuries-old legal distinction between common carriage and private carriage. FAA Advisory Circular AC 120-12A outlines the four core elements that legally define common carriage:
The Four Elements of Common Carriage
- A holding out of a willingness to
- Transport persons or property
- From place to place
- For compensation or hire
If all four elements are present, the operation is common carriage and must be conducted under the air carrier certification rules of 14 CFR Part 121 or Part 135. Operating without such certification is a federal violation subject to severe civil penalties and certificate revocation.
Analyzing "Holding Out"
"Holding out" is the definitive test of common carriage. An operator holds out when communicating to the public, or to a defined segment of the public, that its flight services are available for hire:
- Direct Holding Out: Commercial advertising in print, television, radio, online websites, mobile apps, social media, airport flyers, or business cards offering flight transportation.
- Indirect Holding Out: Utilizing travel agents, ticket brokers, or corporate travel desks to funnel passengers; or cultivating a general reputation through word-of-mouth that the pilot or operator will transport any person who is willing to pay.
- Segment of the Public: An operator does not need to advertise to the entire population. Holding out to a specialized customer segment—such as all doctors in a county, all members of an oil trade association, or all guests at a mountain resort—constitutes holding out under federal case law.
Private Carriage and Its Stringent Limitations
Carriage for compensation or hire that does not involve holding out is known as private carriage. Private carriage is characterized by:
- Flying for one or several selected customers under exclusive, mutually negotiated, long-term bilateral contracts.
- Specialized or custom-tailored flight operations where the carrier does not routinely solicit or add new customers.
- Complete absence of public marketing or holding out.
How Many Customers Is Too Many?
AC 120-12A describes private carriage as carriage for one or several selected customers, generally on a long-term basis. The number of contracts must not be too great, or it implies a willingness to contract with anyone. The AC notes that a carrier operating under 18 to 24 contracts has been held to be a common carrier, while private carriage has been found where three contracts were the operator's sole business. There is no fixed safe number; the test is whether the operator is holding out.
Private carriage is also not a Part 91 loophole. An operator that provides aircraft and crew for compensation in noncommon or private carriage still needs a Part 119 certificate: it operates under Part 135 for airplanes with fewer than 20 passenger seats and less than 6,000 pounds of payload, or under Part 125 for larger airplanes (14 CFR 119.23), unless an exception such as 91.501(b) applies.
The Commercial Pilot's Legal Position: Wet Lease vs. Dry Lease
How can an individual commercial pilot legally exercise commercial privileges without an air carrier certificate? The answer lies in operational control.
The Corporate Pilot Employment Model
A commercial pilot may be employed directly by a company or individual to fly an aircraft that the client owns or dry-leases. In this arrangement:
- The aircraft owner or corporate lessee exercises operational control over the flight (deciding when, where, and why the flight occurs).
- The company pays the commercial pilot a salary or hourly fee strictly for piloting services.
- The company is transporting its own employees, clients, or cargo, and is not selling air transportation to the public.
- This operation is fully legal under 14 CFR Part 91.
The Wet Lease vs. Dry Lease Trap
| Lease Type | Definition | Regulatory Implication |
|---|---|---|
| Dry Lease | Aircraft is leased without flight crew. Lessee provides their own independent flight crew and exercises operational control. | Compliant under Part 91 |
| Wet Lease | Aircraft and at least one crewmember provided together (14 CFR 119.3). | Providing both for compensation is a commercial operation that requires a Part 119 certificate |
Classic Scenario: The "Flight Package"
A commercial pilot owns a twin-engine aircraft. A local manufacturing company approaches the pilot and asks to be flown to a distant facility for $2,000. If the pilot provides both the airplane and acts as pilot, the pilot has entered into a wet lease commercial air transportation agreement. Without a Part 119 operating certificate, this is an illegal charter operation. To remain legal under Part 91, the manufacturing company would have to lease the aircraft from an independent source (dry lease) and independently hire the pilot to fly it.
Commercial Operations Exempted under 14 CFR 119.1(e)
Under 14 CFR 119.1(e), the FAA specifically exempts several commercial flight operations from Part 119 certificate requirements, permitting them to be conducted under the general operating rules of 14 CFR Part 91. (These exceptions do not apply to noncommon-carriage operations in airplanes with 20 or more passenger seats or a payload capacity of 6,000 pounds or more.)
- Student Instruction: Flight training conducted by authorized flight instructors.
- Nonstop Commercial Air Tours: Flights in an airplane, powered-lift, or rotorcraft with 30 or fewer passenger seats and a payload of 7,500 pounds or less, beginning and ending at the same airport within a 25-statute-mile radius, under a 14 CFR 91.147 Letter of Authorization (which includes a drug and alcohol testing program).
- Ferry or Training Flights: Moving aircraft between maintenance facilities or training flight crews.
- Aerial Work Operations:
- Crop dusting, seeding, spraying, and bird chasing (conducted under 14 CFR Part 137).
- Banner towing.
- Aerial photography or survey.
- Fire fighting.
- Powered-lift or rotorcraft operations in construction or repair work.
- Powerline or pipeline patrol.
- Sightseeing Flights in Hot Air Balloons or Gliders.
- Nonstop Parachute Operations: Flights conducted within a 25-statute-mile radius of the departure airport for intentional parachute jumping.
- Emergency Mail Service.
- Rotorcraft External-Load Operations (conducted under 14 CFR Part 133).
Applying 119.1(e) on FAA Knowledge Tests
Ground instructors must emphasize that 119.1(e) exceptions are narrow and specific. An aerial photography flight is exempt under Part 91 only so long as the flight's objective is taking photographs. If the pilot lands at a distant destination and discharges passengers who pay a fee, the operation becomes point-to-point passenger transportation, instantly requiring a Part 135 air carrier certificate.
