Mechanic Privileges & Regulations
Mechanic Privileges & Regulations is a core knowledge area on the AMT — General FAA written exam. This hub collects our 16 in-depth, ACS-aligned mechanic privileges & regulations articles — each written in plain English and grounded in the official FAA handbooks. Work through them below, then drill the topic with practice questions.
FAA Certificated Mechanic Privileges and Limitations Under 14 CFR Part 65
FAA certificated mechanics hold specific privileges to inspect, maintain, and repair aircraft under 14 CFR Part 65, but face firm limitations—including no authority to approve their own work or exercise privileges while impaired.
Supervised Work by Uncertificated Persons Under AMT Supervision
Uncertificated persons may legally perform aircraft maintenance tasks when directly supervised by a certificated AMT, but strict regulatory boundaries govern what work qualifies and how supervision must be conducted.
Returning Aircraft to Service After Maintenance: Logbook Signoff Requirements
After completing maintenance, an FAA-certificated mechanic must make a specific logbook entry and approve the aircraft for return to service — a legal requirement under 14 CFR Part 43 that protects airworthiness and defines mechanic accountability.
Inspection Authorization (IA) Privileges and Requirements
An Inspection Authorization (IA) grants eligible A&P mechanics the authority to conduct annual inspections and approve major repairs/alterations for return to service under 14 CFR Part 65.
Prohibition on Mechanics Approving Their Own Inspections
A certificated mechanic may perform maintenance and approve work for return to service, but FAA regulations strictly prohibit a mechanic from both performing and then independently approving an inspection of their own work — a critical safeguard for aviation safety.
Airframe and Powerplant Rating Scope of Work Differences
An Airframe certificate and a Powerplant certificate each grant distinct, legally defined privileges under 14 CFR Part 65 — understanding exactly what each rating covers (and what it does not) is essential for every AMT.
Progressive Inspection Program Mechanic Responsibilities
A progressive inspection program lets operators spread an aircraft's annual inspection over multiple visits; mechanics must understand their specific legal duties, recordkeeping obligations, and the regulatory boundaries that govern participation.
Annual Inspection vs. 100-Hour Inspection Authority
Annual and 100-hour inspections share identical scope, but only an A&P mechanic with Inspection Authorization may sign off an annual — while any certificated A&P can perform and return a 100-hour aircraft to service.
Recent Experience Requirements for Mechanics: 90-Day Rule Explained
14 CFR Part 65 requires certificated mechanics to have performed work within the past 90 days to exercise their privileges; this article explains exactly what that means and why it matters.
Drug and Alcohol Testing Requirements for Aviation Mechanics
Aviation mechanics working for FAA-regulated employers must comply with strict DOT/FAA drug and alcohol testing rules under 14 CFR Part 120, covering pre-employment, random, post-accident, and other test categories.
FAA Civil Penalty and Certificate Action Process for Mechanics
When an aviation mechanic violates FAA regulations, the agency can respond with civil penalties, certificate suspension, or revocation — understanding this process helps AMTs protect their certificates and their careers.
Mechanic Certificate Duration, Renewal, and Currency Requirements
A mechanic certificate never expires, but exercising its privileges legally requires current experience and a valid inspection authorization—here's exactly what 14 CFR Part 65 demands.
Mechanic Responsibility for Airworthiness of Completed Work
Aviation mechanics bear direct regulatory responsibility for the airworthiness of their completed work under 14 CFR Part 65, and understanding these obligations is essential for both the FAA knowledge test and safe maintenance practice.
Maintenance Record Entries: Required Content and Mechanic Signature Standards
FAA regulations require specific content in maintenance records and mandate that certificated mechanics sign entries with their certificate number—errors or omissions can ground aircraft and jeopardize certificates.
Operating Limitations and Placards: Mechanic Responsibility After Maintenance
After completing maintenance, an AMT must ensure aircraft operating limitations and placards are current, correct, and properly displayed — a legal obligation, not just a courtesy.
Fraudulent or Intentionally False Maintenance Record Entries
Making a fraudulent or intentionally false entry in a maintenance record is a serious federal violation that can end an AMT's career and compromise aviation safety — learn what the rules say and what's at stake.
