Continuing airworthiness is the ongoing process of ensuring that an aircraft continues to meet the applicable airworthiness requirements and remains in a condition for safe operation throughout its operational life.
It covers the technical and organisational activities required after an aircraft enters service, including maintenance-programme control, Airworthiness Directive management, aircraft configuration, technical records, maintenance status and other information used to establish the aircraft’s current airworthiness position.
Within the EASA regulatory framework, continuing-airworthiness requirements are established principally through Regulation (EU) No 1321/2014.
What does Continuing Airworthiness involve?
Continuing airworthiness is maintained through a combination of maintenance, engineering, records and regulatory-control activities.
Depending on the aircraft and operation, these can include:
maintaining and controlling the Aircraft Maintenance Programme (AMP);
monitoring aircraft utilisation;
managing Airworthiness Directives;
controlling modifications and repairs;
maintaining aircraft and component configuration;
managing continuing-airworthiness records;
monitoring defects and deferred items;
coordinating required maintenance;
maintaining reliability programmes where applicable;
ensuring that completed maintenance is properly recorded;
supporting Airworthiness Reviews.
These activities continue throughout the aircraft’s operational life.
Every flight adds utilisation. Components are installed and removed. Maintenance is performed. OEM information changes. Regulatory requirements are introduced or revised.
The continuing-airworthiness process ensures that these changes remain reflected in the technical status of the aircraft.
Continuing Airworthiness vs Airworthiness
Airworthiness describes whether an aircraft is in a condition that meets the applicable requirements for safe operation.
Continuing airworthiness describes the ongoing processes used to maintain that condition over time.
An aircraft may be airworthy at a particular moment, but maintaining that status requires continuous control of maintenance requirements, configuration, regulatory obligations and technical records.
For this reason, continuing airworthiness is not limited to an annual review or audit. It is part of daily aircraft operation.
Who is responsible for Continuing Airworthiness?
Responsibility depends on the type of aircraft and operation.
Within the EASA framework, licensed air carriers are required to have their continuing airworthiness managed by an approved Continuing Airworthiness Management Organisation (CAMO).
Other aircraft may be managed by a CAMO, CAO or owner depending on the regulatory category and type of operation.

Continuing Airworthiness and Aircraft Maintenance
Continuing airworthiness management and aircraft maintenance are closely connected but perform different roles.
The continuing-airworthiness organisation manages the requirements surrounding the aircraft: what maintenance is required, when it is due, how regulatory requirements are controlled and whether the technical status remains properly represented.
An approved maintenance organisation, such as a Part-145 organisation, performs and certifies maintenance within its approved scope.
The CAMO therefore manages the wider technical status of the aircraft, while the maintenance organisation performs the physical maintenance work.
The Aircraft Maintenance Programme
The Aircraft Maintenance Programme (AMP) is a central part of continuing airworthiness.
It defines the scheduled maintenance requirements applicable to the aircraft and establishes when those tasks need to be performed.
The programme may include requirements derived from:
aircraft and engine manufacturers;
Maintenance Review Board information;
Airworthiness Directives;
certification maintenance requirements;
operational experience;
reliability analysis;
additional operator requirements.
The CAMO is responsible for ensuring that the applicable programme remains controlled and appropriate for the aircraft under its management.
Airworthiness Directives and Continuing Airworthiness
Airworthiness Directive management is another important continuing-airworthiness activity.
CAMO and Engineering teams need to monitor new and revised directives, determine whether they apply to the aircraft or components under their control and maintain the resulting assessment and compliance status.
Applicability can depend on aircraft configuration, serial numbers, installed components, modification status and other effectivity criteria.
Read more in our glossary entries for Airworthiness Directive (AD) and AD Applicability.
Continuing-Airworthiness Records
Continuing airworthiness depends on maintaining records that demonstrate the aircraft’s technical history and current status.
These records can include:
maintenance accomplishment;
aircraft and component utilisation;
AD status;
modification and repair status;
component installation and removal history;
maintenance-programme status;
life-limited component information;
aircraft configuration;
supporting technical documentation.
The value of these records depends on more than their existence. Engineering also needs to be able to establish the relationships between them when confirming the aircraft’s current technical status.
Continuing Airworthiness Across Multiple Systems
Modern CAMO operations rarely take place within one software platform.
Information may be distributed across:
the core M&E system;
electronic technical logs;
Technical Records systems;
OEM portals;
regulatory databases;
reliability applications;
engine or aircraft health-monitoring systems;
MRO environments;
spreadsheets and reporting tools.
The M&E system may remain the primary system of record, but CAMO teams often need to bring information together from several environments before reaching an engineering decision.
Read our guide to The Modern CAMO: Managing Airworthiness Across Systems, Records and Operations for a deeper explanation.
Continuing Airworthiness and Compliance Confidence
Maintaining continuing airworthiness requires teams to understand not only whether a requirement has been completed, but also the information supporting that status.
A CAMO may need to establish why an AD was considered applicable or non-applicable, whether aircraft configuration has changed since the assessment, where compliance evidence is held and whether the M&E system reflects the latest engineering position.
EXSYN describes the ability to establish and demonstrate this position consistently as Compliance Confidence.
The CAMO & Continuing Airworthiness solution supports this process by preparing, validating and connecting information across compliance, M&E data consistency, reliability and aircraft transitions while keeping technical decisions with the operator.
Continuing Airworthiness and Airworthiness Reviews
An Airworthiness Review is a formal assessment of the aircraft and its documented continuing-airworthiness status.
It should not be confused with continuing-airworthiness management itself.
Continuing airworthiness happens continuously throughout aircraft operation. The Airworthiness Review provides a formal point at which the aircraft and supporting records are assessed against the applicable requirements.
When technical records, maintenance status, configuration and compliance information are maintained consistently during daily operations, preparation for an Airworthiness Review or regulatory audit becomes considerably more controlled.
