BR-ANAC-IOAR key terms

A regulation issued by ANAC that sets binding requirements in a defined area of Brazilian civil aviation, such as airworthiness, maintenance, or operator certification. Each RBAC is numbered and aligned with ICAO Annex standards.

The Brazilian civil aviation authority responsible for regulating, certifying, and supervising aviation safety, including aircraft airworthiness, maintenance organizations, and air operators. It issues RBACs and conducts surveillance of certificate holders.

A document issued for an individual aircraft confirming that its type design has been approved and that it conforms to that approved design and is safe to operate. It must remain valid through continuing airworthiness maintenance.

An approval granted for an aircraft, engine, or propeller design that demonstrates the design meets applicable airworthiness requirements. It establishes the approved configuration baseline against which individual aircraft conformity is judged.

An approval issued for a change to an already type-certificated product, such as a major modification. It confirms the altered design still complies with airworthiness requirements and defines the approved installation baseline.

A mandatory airworthiness action issued by the state of design and adopted by the state of registry to correct an unsafe condition. Compliance is compulsory and must be recorded and tracked in maintenance records.

The set of processes ensuring an aircraft remains in a condition that meets its type design and is safe to operate throughout its service life. It covers maintenance, inspections, modifications, repairs, and defect control.

A documented schedule of maintenance tasks, intervals, and procedures approved for an aircraft type or operator, designed to preserve airworthiness. It defines what work is done, when, and by whom, and is subject to authority approval.

A document produced by a board representing the type certificate holder and authorities that defines the minimum scheduled maintenance tasks and intervals needed to maintain airworthiness. Operators use it to build their own maintenance programmes.

A maintenance or inspection task, often structural or life-limited, that is mandated as part of the type design and cannot be altered without design approval. It is distinct from tasks derived from the MRB process.

An organisation certified by the competent authority to perform maintenance, repair, or overhaul on aircraft or components within defined ratings. It must hold approved procedures, qualified personnel, and suitable facilities.

Personnel authorised by a maintenance organisation to certify that maintenance work has been completed satisfactorily and to sign a release to service. Their authorisation depends on training, experience, and formal qualification.

A formal declaration, signed by authorised staff, that specified maintenance has been completed to approved standards and the aircraft or component is fit for return to service. It is a legal record of maintenance accomplishment.

Documentation that records work performed, defects found, parts installed, and certifications made during maintenance. Records must be legible, retained for required periods, and traceable to the aircraft or component.

An aircraft document used to record defects, deferred items, and maintenance actions between scheduled checks, providing a running history of the aircraft's condition. It supports airworthiness control and defect rectification tracking.

An approved document specifying which instruments or equipment may be inoperative while the aircraft remains airworthy, subject to defined conditions and procedures. It allows controlled dispatch with known defects.

An approved list identifying external parts of an aircraft type that may be missing at dispatch, together with any associated performance penalties. It differs from the MEL, which addresses equipment systems.

A certificate issued to an operator authorising commercial air transport operations, specifying the types of aircraft and areas of operation permitted. It requires demonstrated compliance with operational and maintenance requirements.

A structured management framework for identifying hazards, assessing and controlling risks, and continuously improving safety performance. It includes policy, risk management, assurance, and promotion components and is required for many certificate holders.

The process of estimating the likelihood and severity of a hazard's consequences and deciding whether the resulting risk is acceptable. It supports prioritisation of mitigation actions within a safety management system.

The mandatory or voluntary submission of information about accidents, incidents, or other safety events to the authority or organisation. Reports feed safety analysis and preventive action rather than blame.

An organisational approach that distinguishes honest error from reckless or intentional misconduct, encouraging open reporting without fear of punitive action for inadvertent mistakes. It balances accountability with learning.

The shared values, attitudes, and behaviours of an organisation that determine how seriously safety is treated in daily decisions. It is reflected in reporting willingness, leadership commitment, and learning from failure.

The study of how human capabilities and limitations interact with equipment, procedures, and environments, applied to reduce error and improve performance. In maintenance it addresses fatigue, communication, workload, and documentation.

A commonly taught set of twelve human-factor precursors to maintenance error, including fatigue, pressure, distraction, lack of communication, and complacency. It is used in training to help staff recognise and counter error-producing conditions.

The component of a safety management system that monitors whether safety controls remain effective, using audits, data analysis, and performance indicators. It triggers corrective action when performance falls short of expectations.

A systematic, independent examination of processes, records, and practices against defined requirements to determine conformity and effectiveness. Findings are classified by significance and followed up with corrective action.

The ongoing oversight activities by an authority or organisation to verify that certificate holders continue to meet requirements. It includes inspections, audits, ramp checks, and review of reported data.

An action taken to eliminate the cause of a detected nonconformity or deficiency so it does not recur. It is distinguished from immediate containment and must be verified for effectiveness.

The categorisation of audit or inspection findings by severity, typically into levels such as minor, major, or critical, which determines the required response time and whether certification action follows.

One of the international standards and recommended practices adopted under the Chicago Convention, covering areas such as airworthiness, operations, and personnel licensing. Contracting states incorporate them into national regulation.

The provisions in ICAO Annexes that states are expected to implement; standards are mandatory in nature while recommended practices are desirable. Differences from them must be notified to ICAO.

The 1944 international treaty establishing ICAO and the framework for civil aviation, including state responsibility for airworthiness and recognition of certificates. It underpins most bilateral and multilateral aviation arrangements.

The process of aligning national regulations, procedures, and certification practices with international standards so approvals are mutually recognised and safety oversight is consistent across states. It reduces duplication and regulatory burden.

An arrangement between two states under which each accepts certain airworthiness findings and approvals issued by the other, such as type certificates or maintenance approvals. It facilitates trade and reduces duplicate certification work.

Formal recognition that a product, part, or appliance design meets applicable airworthiness requirements, issued through a type certificate, supplemental type certificate, or equivalent process. It precedes individual conformity certification.

A change to an aircraft's type design that may appreciably affect weight, balance, structural strength, performance, or operating characteristics. It requires approved design data before installation and recording.

A document issued by a design or production organisation recommending or requiring inspection or modification of in-service products. It becomes mandatory only when adopted by an airworthiness directive or regulation.

The documented organisational structure, responsibilities, procedures, and resources established to ensure maintenance and oversight activities meet required standards. It includes independent monitoring of compliance.
