Continued Airworthiness of Small Drones
This closing lesson brings the module together by answering a question new remote pilots often ask: does my drone need an FAA airworthiness certificate like a manned airplane does? For the overwhelming majority of Part 107 operations, the answer is no. This lesson explains what an airworthiness certificate actually is in manned aviation, why most small unmanned aircraft never need one, and what a remote pilot has instead: the same ongoing 14 CFR 107.15 duty covered throughout this module, now understood as the practical substitute for a certificate-based continued-airworthiness program.
The manned-aircraft certificate model, for context
A manned aircraft operated under 14 CFR Part 91 generally must carry an effective airworthiness certificate on board, a requirement found in 14 CFR 91.203. That certificate is tied to a type certification process: the aircraft's design has been reviewed and approved under 14 CFR Part 21, and the specific airplane has been found to conform to that approved design and to be in condition for safe operation at the time of certification. From that point forward, a structured, prescriptive continued-airworthiness system (periodic inspections, maintenance records, and in some cases FAA Airworthiness Directives) keeps that original certificate valid over the aircraft's operating life. This is context for comparison — it describes manned aviation, not a Part 107 sUAS requirement.
Most sUAS operated under Part 107 need no airworthiness certificate
State this directly, because it is a frequent point of confusion: a small unmanned aircraft operated under Part 107 generally does not need to hold an FAA-issued airworthiness certificate the way a Part 91 manned aircraft does. Part 107 does not send an sUAS through the Part 21 type-certification process, and it does not require the aircraft to carry an airworthiness certificate on board. This is one of the clearest structural differences between how Part 107 regulates small drones and how the rest of Title 14 regulates manned aircraft — and it is a direct consequence of Part 107 being built as a performance-based framework rather than a certification-based one.
The practical equivalent: 107.15's continuous self-assessment duty
If there's no certificate, what replaces it? The answer is the regulation this entire module has been built around: 14 CFR 107.15. Where a manned aircraft's airworthiness is established once (at certification) and then maintained through a periodic inspection program, a small UAS operated under Part 107 has no equivalent one-time or periodic certification event. Instead, the remote pilot in command personally re-establishes the aircraft's safe condition before every single flight, and continues to monitor it throughout that flight, exactly as 107.15(a) and 107.15(b) require. The burden that a certificate and an inspection program carry in manned aviation is carried entirely by the remote pilot's judgment, applied fresh every time, in the Part 107 world.
- Manned aviation: certificate issued once (at type certification and conformity), then maintained through periodic, scheduled inspections and records.
- Part 107 sUAS: no certificate; the remote pilot performs a fresh, complete safety self-assessment before every flight and continuously through it, under 107.15.
Are there sUAS operations where an airworthiness certificate does apply?
Yes, in limited circumstances that fall outside the scope of a typical Part 107 sUAS operation — for example, certain larger unmanned aircraft, some beyond-visual-line-of-sight operations conducted under a type certificate rather than a standard Part 107 waiver, and specific government or public-aircraft operations can involve airworthiness certification requirements. These situations are the exception, not the rule, for the sUAS covered by this course, and going into their specific requirements is beyond the scope of the standard Part 107 knowledge test. For essentially all typical Part 107 commercial and recreational sUAS operations, the 107.15 model described above is what actually applies.
Manned aircraft rely on a certificate-based continued-airworthiness system; most Part 107 sUAS rely instead on the remote pilot's ongoing 14 CFR 107.15 self-assessment duty.
View Larger| Element | Manned aircraft (Part 91) | Part 107 small UAS |
|---|---|---|
| Certification basis | Type certification under Part 21; airworthiness certificate required under 91.203 | No airworthiness certificate generally required |
| How safety is re-established over time | Periodic, scheduled inspections and maintenance records under Part 43 | Remote pilot's inspection before every flight under 14 CFR 107.15(a) |
| Who carries the ongoing safety burden | Shared between certificated mechanics, inspection programs, and the pilot | Almost entirely the remote pilot in command's own judgment |
| In-flight duty if a problem is found | Pilot-in-command authority to respond to the emergency | Remote pilot must discontinue flight under 14 CFR 107.15(b) |
Bringing the Module Together: A Remote Pilot's Ongoing Airworthiness Equivalent
How the four lessons in this module combine into the practical substitute for a certificate-based continued-airworthiness program.
Start from the underlying duty: 14 CFR 107.15
Every flight begins with the same requirement covered in Lesson A: the aircraft must be in a condition for safe operation, confirmed by the remote pilot's own inspection.
Use manufacturer guidance to know what "safe" means for this airframe
Lesson B's manufacturer maintenance guidance fills in the aircraft-specific details 107.15 does not spell out, from component life limits to firmware updates.
Keep records that support the case that the standard was met
Lesson C's voluntary recordkeeping builds a demonstrable history, useful under 14 CFR 107.7 if a remote pilot's compliance is ever questioned.
Repeat the whole process before every flight, indefinitely
Unlike a certificate that is issued once and periodically renewed, this self-assessment has no expiration and no substitute — it runs for as long as the aircraft is operated.
| Mistake | Why it happens | Correct understanding | Regulation / source |
|---|---|---|---|
| Assuming a drone needs an FAA airworthiness certificate before it can be flown commercially | Manned-aviation training treats an airworthiness certificate as a universal requirement | Most sUAS operated under Part 107 do not require an airworthiness certificate; the requirement does not carry over from Part 91. | 14 CFR Part 107 (no certificate requirement); 14 CFR 91.203 (manned-aircraft context) |
| Confusing FAA aircraft registration with airworthiness | Both involve paperwork and the FAA | Registration under Part 48 identifies who owns the aircraft; it says nothing about whether the aircraft is currently in a condition for safe operation. | 14 CFR Part 48 (registration); 14 CFR 107.15 (safe condition) |
| Believing that meeting 107.15 once means the aircraft is "certified safe" going forward | Treating the preflight check like a one-time certificate event | 107.15's duty is ongoing and applies fresh before every flight; there is no lasting certification carried forward. | 14 CFR 107.15(a) |
| Assuming manufacturer compliance alone satisfies 107.15 without the pilot's own assessment | Manufacturer guidance feels authoritative enough to skip a personal check | 107.15 places the inspection duty on the remote pilot personally, regardless of how well the manufacturer's guidance has otherwise been followed. | 14 CFR 107.15(a) |
Does my drone need an FAA airworthiness certificate to operate under Part 107?
Generally no. Most small unmanned aircraft operated under Part 107 do not require an FAA-issued airworthiness certificate, unlike manned aircraft under Part 91. Certain larger or specialized unmanned aircraft operations outside the typical Part 107 scope can involve airworthiness certification, but that is the exception, not the rule.
What's the difference between registration and airworthiness?
Registration under 14 CFR Part 48 identifies who owns a given aircraft and is a separate legal requirement. Airworthiness, and its Part 107 equivalent under 107.15, concerns whether the aircraft is actually safe to fly. An aircraft can be properly registered and still not be in a condition for safe operation on a given day.
Is there a "continued airworthiness program" required for sUAS like there is for manned aircraft?
No formal, prescriptive continued-airworthiness program is required by Part 107. The practical equivalent is 14 CFR 107.15's ongoing requirement for the remote pilot to inspect the aircraft before every flight and discontinue flight if it becomes unsafe.
Does passing a 107.15 inspection once mean I'm covered for future flights?
No. The 107.15 duty applies before every individual flight, not as a one-time or periodic event. Each flight requires its own fresh inspection and assessment, regardless of how the aircraft performed previously.
