BR-ANAC-CMS study guide
BR-ANAC-CMS · Work through your exam, one topic at a time.
The ANAC Continuing Maintenance Schedule (CMS) is a Brazilian civil aviation knowledge assessment tied to continuing airworthiness and maintenance training under ANAC oversight. It is intended for licensed maintenance personnel, maintenance organisation staff, and candidates preparing to work within Brazil's regulated maintenance environment, including those converting or validating foreign credentials. The BR-ANAC-CMS study guide has 8 sections and about 2,560 words.
01Airworthiness Requirements and Regulatory Framework
Airworthiness is the demonstrated fitness of an aircraft, its components, and its maintenance arrangements to operate safely within an approved envelope. A candidate must distinguish initial airworthiness (type certificates, production certificates, design approval, conformity) from continuing airworthiness (maintenance, inspection, modifications, airworthiness directives, and the operator's or owner's obligations).
382 words, about 2 min02Maintenance Organization and Responsibilities
An approved maintenance organization (AMO) operates under a documented exposition or manual that defines its scope of work, facilities, tooling, personnel, procedures, and quality system. The candidate must understand the accountable manager , who has corporate authority for compliance and resourcing, and the quality/independent inspection function that monitors compliance rather than performing production work.
335 words, about 2 min03Maintenance Planning and Scheduling
Maintenance planning translates the approved maintenance programme into scheduled checks, task cards, and work packages. Candidates must understand hard-time tasks (interval-driven replacement or overhaul), on-condition tasks (inspection or test to a limit), and condition-monitoring tasks (data trending without a fixed limit).
334 words, about 2 min04Aircraft Systems and Structures
Candidates need functional knowledge of airframe structures (primary and secondary structure, load paths, fatigue-critical areas, corrosion-prone zones) and the major systems: hydraulic, pneumatic, electrical, fuel, flight controls, landing gear, ice and rain protection, and pressurization. Understand the difference between fail-safe and safe-life design philosophies and what each means for inspection strategy.
299 words, about 1 min05Inspection, Testing, and Troubleshooting
Inspection methods include visual, borescope, eddy current, ultrasonic, radiographic, dye penetrant, and magnetic particle techniques. Candidates should know what each method detects and its limitations: penetrant finds surface-breaking defects in non-porous materials; magnetic particle works only on ferromagnetic materials; ultrasonic detects internal flaws and requires couplant; radiography reveals internal density differences but poses safety considerations.
311 words, about 2 min06Repair, Alteration, and Return to Service
A repair restores an item to an airworthy condition; an alteration changes its configuration or characteristics. Both must be accomplished using approved data : manufacturer structural repair manuals, approved engineering documents, or regulator-approved data.
311 words, about 2 min07Maintenance Records and Documentation
Records provide the traceability that makes airworthiness verifiable. Candidates must understand what must be recorded: work performed, approved data used, parts and materials installed with traceability, personnel who performed and certified the work, dates, and results of inspections and tests.
301 words, about 2 min08Safety Management and Human Factors
Safety management systems provide a structured way to identify hazards, assess and mitigate risk, and assure that mitigations remain effective. Candidates should know the four pillars: policy and objectives , risk management , assurance , and promotion .
