Authorisation and Licence Breaches

CASA enforcement often involves allegations that a person or organisation conducted aviation activity without the correct authority, approval, licence, medical certificate, flight review, instrument proficiency check or recency requirement. These can be strict liability matters, even where the underlying flight or operation appeared routine.

Airworthiness and Maintenance Control

Maintenance and airworthiness matters may involve operating an aircraft that is not airworthy, failing to comply with airworthiness directives or maintenance schedules, defect-recording failures, expired maintenance releases or poor maintenance-control systems.

Part 99 Drug and Alcohol Matters

CASR Part 99 creates obligations around Drug and Alcohol Management Plans, Safety-Sensitive Aviation Activities and CASA testing. Allegations may involve positive or non-negative tests, refusal issues, DAMP defects, training gaps or failures to stand down affected personnel.

Safety Management and Operational Control

CASA investigations can examine whether an operator had effective safety controls, clear accountabilities, training evidence, reporting pathways and a documented response to known hazards.

Operational Non-Compliance

Operational offences can include low flying, dangerous operation, fuel planning breaches, weight and balance errors, failure to comply with ATC instructions, flight-rule breaches and failure to carry required documents. These matters are often identified through surveillance, audits, incident reports or post-event review.

Licence, Authorisation and Approval Risk

Aviation matters can have consequences beyond the immediate allegation. They may affect pilots, maintainers, managers, contractors, organisational approvals, DAMP compliance and future dealings with CASA.

Incident and Enforcement Response

After an incident, audit finding or CASA notice, early decisions about statements, records, corrective action and regulator communication can shape the legal outcome.

1

Review

Send the CASA notice, correspondence, allegation or incident material and identify any response deadline.

2

Assess

Greg assesses the legal, operational and licence exposure and identifies the evidence needed for a defensible response.

3

Respond

Prepare statements, correspondence, submissions, corrective action or representation with a clear strategy.

CASA Investigation Response

We help clients respond to CASA enquiries, notices, interview requests and document requests with a clear view of legal exposure and operational impact.

DAMP and Testing Issues

We advise on Part 99 compliance, SSAA coverage, DAMP procedures, test results, refusals, stand-down decisions and evidence needed to support a response.

Licence and Approval Consequences

We help identify risks to licences, authorisations, approvals and roles, then prepare a strategy that addresses both immediate and longer-term consequences.

Evidence and Systems Review

We review SMS records, DAMP manuals, training files, testing records, internal reports, risk controls and corrective actions to prepare a defensible response.

Court and Tribunal Representation

Where a matter escalates, we provide legal advice, representation and resolution strategy for prosecutions, enforcement outcomes and related proceedings.

Corrective Action Support

We help operators update DAMP, SMS, training and supervision controls so improvement work is practical, documented and aligned with regulatory expectations.

Protect People and Permissions

In aviation, regulatory action can affect individuals and the organisation at the same time. We help identify who needs advice, what information should be gathered and how to manage responses without increasing exposure.That includes advice for pilots, SSAA workers, managers, contractors and organisations with DAMP obligations.

Show the System, Not Just the Incident

CASA will often look beyond one event to the systems that should have prevented, detected or managed the issue. We help clients present the full compliance context, including training, reporting, controls, supervision and corrective action.Where gaps exist, we help repair them in a way that is practical and proportionate.
