Understanding Immediately and Routinely Reportable Matters
Incident Reporting Is a Legal and Operational Requirement
Incident reporting is not optional.
Under Australian aviation law, RPAS operators must report certain safety occurrences to the Australian Transport Safety Bureau (ATSB).
This applies to:
- operations conducted under a ReOC
- certain operations involving larger or higher-risk RPAS
Within your operation:
All personnel must report safety occurrences internally — the CRP is responsible for external reporting
What Is a Safety Occurrence?
A safety occurrence is:
Any event that affects, or could affect, the safety of an RPAS operation
This includes:
- incidents
- near misses
- equipment failures
- operational deviations
Not all occurrences are reportable to the ATSB — but all should be:
captured internally and assessed
Two Types of Reportable Matters
ATSB reporting is divided into two categories:
- Immediately Reportable Matters (IRM)
- Routinely Reportable Matters (RRM)
Understanding the difference is critical.
Immediately Reportable Matters (IRM)
What Is an IRM?
An Immediately Reportable Matter is a serious occurrence that requires urgent notification.
These are events with:
- significant safety consequences
- high potential for harm
- broader aviation safety implications
Examples in RPAS Operations
IRM events may include:
- fatal injury
- serious injury
- major structural damage to the aircraft
- aircraft missing or inaccessible
- loss of separation with another aircraft
- serious third-party property damage (≥ $25,000)
- collision with an animal (including birds)
Reporting Timeframe
IRM must be:
- Reported immediately by phone
- Followed by a written report within 72 hours
Immediate means as soon as reasonably practicable — not the end of the day
Routinely Reportable Matters (RRM)
What Is an RRM?
A Routinely Reportable Matter is a significant safety occurrence that does not meet the threshold of an IRM but still requires formal reporting.
Examples in RPAS Operations
- RRM events may include:
- events that could affect operational safety
- aircraft missing
- serious aircraft damage
- loss of separation with another aircraft
- emergency declarations
- external aircraft-related incidents
Reporting Timeframe
RRM must be:
- Reported within 72 hours via an ATSB Occurrence Notification
RPAS Weight and Operational Context Matters
Reporting requirements vary depending on:
- aircraft weight
- certification status
- operational category
RPA Over 25 kg (or Certified Operations)
Both IRM and RRM apply.
These operations have:
- higher regulatory expectations
- broader reporting requirements
RPA Between 250 g and 25 kg (ReOC Operations)
Reportable events include:
- serious damage
- missing aircraft
- loss of separation
- serious injury or damage
IRM and RRM thresholds still apply.
RPA Under 250 g (and Excluded Category)
In most cases:
- ATSB reporting is not required
However:
Internal reporting and safety management still apply
Who Is Responsible for Reporting?
Within a ReOC operation:
All Personnel
- Must report safety occurrences internally
- Must notify the CRP as soon as practical
Chief Remote Pilot (CRP)
The CRP is responsible for:
- assessing the occurrence
- determining if it is reportable
- submitting reports to the ATSB
- ensuring timeframes are met
The CRP is the central point of accountability for safety occurrence reporting
CEO / Responsible Manager
The CEO is responsible for:
- ensuring reporting systems exist
- ensuring compliance with reporting obligations
- supporting safety oversight
What Must Be Preserved After an Incident
Following a reportable occurrence:
All personnel must take reasonable steps to preserve:
- flight logs
- telemetry data
- operational records
- aircraft components
These may be required for:
regulatory review
Internal Reporting Still Matters
Not all events are ATSB reportable.
However, all operators should maintain:
- incident reports
- hazard reports
- near miss reporting
- safety occurrence registers
This supports:
DDI safety monitoring
Common Mistakes
We frequently see operators:
- not understanding IRM vs RRM thresholds
- delaying reporting
- failing to report near misses internally
- not preserving data after an incident
- assuming small drones remove reporting obligations
Incident Reporting in CRP Assessment
CRP candidates should be able to:
- define IRM and RRM
- identify reportable scenarios
- explain reporting timeframes
- describe who is responsible
- link reporting to safety management
This is commonly assessed through:
scenario-based questions
Practical Reporting Workflow
A simple process:
- Identify the occurrence
- Ensure immediate safety
- Notify the CRP
- Determine IRM or RRM
- Report within required timeframe
- Preserve evidence
- Record internally
- Implement corrective actions
How Uncrewed Approvals Can Help
We support operators to:
- develop reporting procedures aligned with CASA and ATSB
- train personnel on reporting thresholds
- integrate reporting into SMS and DDI frameworks
- prepare for audits and regulatory reviews
We help operators move from:
basic compliance → structured safety intelligence
Frequently Asked Questions
What is the difference between IRM and RRM?
IRM are serious events requiring immediate reporting. RRM are significant events reported within 72 hours.
Who submits the ATSB report?
Do I need to report near misses?
Yes — internally. Some may also meet ATSB reporting thresholds.
What if I am unsure?
Err on the side of caution — report and assess.
Report Early. Protect the Operation.
Incident reporting is not just about compliance.
It is about:
- understanding what went wrong
- preventing recurrence
- demonstrating control of your operation
If it is not reported, it cannot be managed
