In the event of a drone incident in Australia, you must prioritize immediate safety through the ANCA/CANCA framework and fulfill legal obligations by reporting to the ATSB. ANCA (Air Navigation Casualty Assessment) is used for standard incidents, while CANCA (Critical ANCA) applies to life-threatening or high-risk emergencies. Most commercial drone accidents must be reported to the ATSB within 72 hours.
Professional drone operations are built on a foundation of safety, but even the most seasoned pilots must be prepared for the unexpected. Whether you are operating under a Remote Pilot Licence (RePL) or a Remote Operator’s Certificate (ReOC), how you handle those first few seconds of an emergency, and the hours that follow, defines your professionalism and protects your legal standing.
At Ace Aviation Aerospace Academy, we teach our students that an emergency doesn't end when the drone hits the ground. It ends when the paperwork is filed, the risks are mitigated, and the lessons are learned. This handbook serves as the definitive guide to the ANCA/CANCA emergency framework and the mandatory ATSB (Australian Transport Safety Bureau) reporting requirements for the modern Australian drone industry.
What is the ANCA/CANCA Framework?
In the high-stakes world of aviation, acronyms aren't just jargon, they are life-saving protocols. Within the Ace Aviation training ecosystem, we utilize the ANCA and CANCA frameworks to help pilots rapidly categorize the severity of an incident. This classification dictates the speed and scale of the emergency response.
1. ANCA: Air Navigation Casualty Assessment
ANCA is the primary assessment framework used when a drone incident occurs that does not involve immediate life-threatening harm but represents a significant breach of safety or navigation standards.
When it applies:
- A drone crash resulting in minor property damage.
- A "Flyaway" incident where control is lost but no immediate collision occurs.
- A "Loss of Separation" with another unmanned aircraft.
- Minor equipment failure that leads to an emergency landing.
Who needs it: Every RePL holder and ReOC Chief Pilot should have ANCA protocols embedded in their standard operating procedures (SOPs).
2. CANCA: Critical Air Navigation Casualty Assessment
CANCA is an escalation of the standard assessment. It is triggered when the incident reaches a "Critical" threshold. This is the "Code Red" of drone operations.
Critical Thresholds for CANCA:
- Human Injury: Any incident involving a person being struck by the aircraft or injured during the operation.
- Manned Aircraft Conflict: A near-miss or collision with a crewed aircraft (helicopter, plane).
- Critical Infrastructure: Impact with power lines, government buildings, or major transport hubs.
- High-Density Risk: A crash into a crowded area, such as a busy street in Sydney or Melbourne.
ATSB Reporting Requirements: What You Legally Must Do
While ANCA and CANCA are operational frameworks for assessment, the ATSB reporting requirements are a legal mandate under the Transport Safety Investigation Act 2003. Failing to report an "Immediately Reportable Matter" is a criminal offense.
Mandatory vs. Voluntary Reporting
The ATSB differentiates between what must be reported and what should be reported to improve industry safety.
1. Immediately Reportable Matters (IRM)
These must be reported to the ATSB by telephone as soon as reasonably practicable.
- Death or serious injury.
- The aircraft is missing.
- The aircraft is completely inaccessible.
- Serious damage to the aircraft or third-party property.
2. Routine Reportable Matters (RRM)
These must be reported in writing (via the ATSB website) within 72 hours.
- Minor injuries.
- Flight control system malfunctions.
- Structural failure of the RPA.
- Loss of separation with another aircraft.

Step-by-Step Emergency Response for Drone Pilots
When the alarm sounds or the telemetry turns red, follow this verified process used by Ace Aviation professionals across Brisbane, Perth, and Hobart.
Step 1: Immediate Aviation Safety (The "AV" in ANCA)
The priority is to navigate the aircraft to a safe area. If control is lost, execute your pre-planned emergency procedures.
- Manual Override: Attempt to switch to a non-GPS mode if a flyaway is suspected.
- Kill Switch: If the aircraft is heading toward a crowd in a city like Sydney, and you have a terminated flight system, use it.
Step 2: Site Security and Casualty Assessment
Once the aircraft is down, secure the site.
- Assess for Injuries: This is where the CANCA framework begins. Check if anyone has been hit.
- Fire Risk: LiPo batteries are prone to "thermal runaway" after a crash. Keep a fire extinguisher or fire blanket ready.
Step 3: Notification and Coordination
- Inform Air Traffic Control (ATC): If you are operating in controlled airspace near Melbourne or Brisbane airports, notify ATC immediately if the drone is no longer under your control.
- The "Responsible Person": Under ATSB rules, the pilot, the operator, and the owner are all responsible for ensuring the report is made.
Step 4: Evidence Preservation
Do not move the drone unless it poses an immediate fire hazard or safety risk. Take high-resolution photos of the wreckage, the surrounding area, and any damage to third-party property.
Real-World Scenarios
Scenario A: The Melbourne Flyaway (ANCA)
A pilot in Melbourne is conducting a roof inspection when the drone loses GPS lock due to urban "canyoning." The drone drifts toward a park. The pilot follows ANCA protocols, warns bystanders, and regains control in ATTI mode to land safely in a clearing.
- Action: Internal ReOC log entry. No ATSB report required as no injury or damage occurred.
Scenario B: The Sydney Harbour Collision (CANCA/ATSB)
A commercial drone filming near a ferry wharf in Sydney suffers a motor failure and strikes a parked vehicle, shattering the windshield.
- Action: Immediate CANCA assessment. Since there is significant third-party property damage, it is a Routine Reportable Matter for the ATSB. The pilot must file a written report within 72 hours.
Scenario C: The Perth Airport Intrusion (CANCA/ATSB IRM)
During a survey near Perth, a drone experiences a total link loss and climbs into the approach path of a commercial airliner.
- Action: This is an Immediately Reportable Matter (IRM). The pilot must call the ATSB and the local tower immediately.
Common Mistakes Drone Pilots Make in Emergencies
- Failing to Report to the ATSB: Many pilots think that if CASA doesn't see it, it didn't happen. The ATSB and CASA share data. Failing to report an accident can lead to the suspension of your RePL or ReOC.
- Panicking during a Flyaway: Modern drones have multiple fail-safes. Pilots often forget to switch to manual modes or use the "Return to Home" override.
- Moving the Evidence: Moving a drone before documenting the scene can hinder an investigation, especially in a CANCA-level event.
- Incomplete Logs: Professionalism is defined by your paperwork. If your logs don't show pre-flight checks, you are liable for "negligence" rather than "equipment failure."
CASA Regulatory Context: RePL and ReOC
It is important to understand that the CASA (Civil Aviation Safety Authority) is the regulator that issues your license, but the ATSB is the body that investigates why things went wrong.
As a Remote Pilot Licence (RePL) holder, you are the pilot in command (PIC). You are responsible for the safe operation of the aircraft. If you work for a company with a Remote Operator’s Certificate (ReOC), you must also follow their internal Operations Manual, which should detail their specific ANCA/CANCA-style emergency workflows.

Extensive FAQ: Drone Emergencies and Reporting
1. Do I have to report a crash if only my drone is damaged?
If your drone is a Type 2 RPA (most commercial drones under 25kg), you generally must report a crash that results in damage to the RPA itself as a Routine Reportable Matter (within 72 hours).
2. What is the definition of a "Serious Injury" for ATSB reporting?
A serious injury includes anything requiring hospitalization for more than 48 hours, a bone fracture (excluding fingers/toes), or severe hemorrhaging.
3. If I am a hobbyist, do I still need to follow ANCA/CANCA?
While ANCA/CANCA is a professional framework taught at Ace Aviation, the logic applies to everyone. However, hobbyists have different ATSB reporting requirements (mostly voluntary) but must still follow CASA safety rules.
4. Who do I call for an "Immediately Reportable Matter"?
You should call the ATSB 24-hour incident reporting line at 1800 011 034.
5. Can I be fined for reporting an accident?
The ATSB is a "no-blame" investigatory body. Their goal is safety, not punishment. However, if the report reveals a gross violation of CASA regulations, CASA may take separate action.
6. Does ANCA apply to bird strikes?
Yes. A bird strike is an "Air Navigation" event. You should assess the damage and determine if the aircraft's safety was compromised.
7. What happens if I don't report a "Near Miss" with a plane?
This is a "Loss of Separation" and is an Immediately Reportable Matter. If caught, you risk losing your license and facing significant fines under the TSI Act.
8. Is a lost data link considered an emergency?
If the data link does not recover and the drone does not return to home as programmed, it becomes an ANCA/CANCA incident depending on where it is flying.
9. Do I need to report a crash in my own backyard?
If you are operating commercially (RePL/ReOC), yes, the location doesn't exempt you from reporting requirements.
10. How long should I keep records of an ANCA assessment?
Under ReOC requirements, you should keep operational logs and incident reports for at least seven years.
11. What is the difference between a "Serious Incident" and an "Accident"?
An Accident involves death, serious injury, or destruction of the aircraft. A Serious Incident is an event where an accident "nearly occurred." Both are reportable.
12. Does the ATSB investigate every drone crash?
No. They prioritize incidents that offer significant safety lessons or involve manned aircraft risk.
13. Can a "Responsible Person" be the drone owner who wasn't at the site?
Yes. The owner is a "responsible person" and has a legal obligation to ensure a report is made.
14. What if I crash in a remote area with no people?
You still need to assess the aircraft (ANCA) and report to the ATSB if the damage meets the threshold.
15. Does Ace Aviation provide templates for incident reporting?
Yes, our Altitude+ program provides students and ReOC holders with templates for ANCA/CANCA assessments and logs.
16. What is a "Type 1 RPA"?
A Type 1 RPA is a large drone (over 150kg) or a medium drone (25kg-150kg) that is type-certified. These have the highest level of mandatory reporting.
17. What is REPCON?
REPCON is the ATSB's confidential reporting scheme. You can use it to report safety concerns or hazards without your identity being revealed to the regulator.
Summary
Handling a drone emergency requires more than just stick skills: it requires a structured mental framework and a thorough understanding of Australian aviation law. By using the ANCA and CANCA assessment frameworks, pilots can stay calm and prioritize safety during the most stressful moments of their careers. Furthermore, staying compliant with ATSB reporting requirements ensures that the industry remains transparent and continues to improve.
