Module 10: Maintenance and Inspection Procedures
A small unmanned aircraft is a mechanical and electrical system, and every one of those systems can degrade, fail, or simply arrive at a flight in worse condition than it left the last one. This module covers ACS Task V.F: the remote pilot's legal duty to make sure the aircraft is fit to fly, both right now (before this specific flight) and over time (as components age, wear, and are updated). Unlike manned aviation, Part 107 does not hand a remote pilot a prescriptive maintenance schedule or a certificate to renew — it hands them a single, ongoing performance standard and expects them to meet it using their own judgment, the aircraft manufacturer's guidance, and good practice.
Learning outcomes
- State 14 CFR 107.15's condition-for-safe-operation requirement in full, including the duty to inspect before every flight and to discontinue flight when the aircraft is no longer safe.
- State 14 CFR 107.49's preflight familiarization, inspection, and actions requirements in full, including every listed element.
- Explain why Part 107 names no specific maintenance schedule, and how a manufacturer's maintenance and service guidance functions as the practical standard for meeting 107.15 on a specific airframe.
- Explain that Part 107 does not mandate a formal maintenance logbook, and why keeping records anyway supports compliance with 14 CFR 107.7.
- Explain why most sUAS operating under Part 107 do not require an FAA airworthiness certificate, and how 107.15's ongoing self-assessment duty serves as the practical equivalent.
Everything in this module radiates outward from a single regulation: 14 CFR 107.15, which requires a small unmanned aircraft system to be in a condition for safe operation and requires the remote pilot in command to inspect it before every flight and to discontinue flight the moment it stops being safe. That single sentence-and-a-half does more legal work in this module than any other rule, because Part 107 — unlike Part 91 and Part 135 for manned aircraft — does not layer a separate, prescriptive maintenance program (inspection intervals, mechanic sign-offs, airworthiness directives) on top of it.
The four lessons in this module work outward from that one regulation, in order. Lesson A covers the immediate, every-flight side of the duty: 14 CFR 107.49's specific preflight familiarization and inspection requirements. Lesson B covers the elapsed-time side: how a manufacturer's maintenance and service guidance for a specific airframe becomes the practical way a remote pilot keeps meeting 107.15 as components age. Lesson C addresses recordkeeping — explicitly not mandated as a formal logbook under Part 107, but tied to a real, separate obligation under 14 CFR 107.7 to make the aircraft and any required records available to the FAA on request. Lesson D closes the module by contrasting this whole performance-based approach with the certificate-based continued-airworthiness framework used for manned aircraft, and explaining what a remote pilot actually has instead.
Nothing in this module requires a mechanic's certificate, a type rating, or specialized tools. It requires understanding one regulation deeply, and understanding how a remote pilot actually goes about satisfying it in practice, flight after flight, aircraft after aircraft.
