Understanding Aircraft Incidents and Accidents
Introduction
Understanding the definitions of incidents and accidents is crucial for pilots, as it forms the foundation for safety awareness and regulatory compliance. This section outlines the official definitions of these terms within the context of Australian aviation, as governed by the Aviation Transport Safety Bureau (ATSB) and the Civil Aviation Safety Authority (CASA). It also highlights the alignment with international standards set by the International Civil Aviation Organization (ICAO).
Definition of an Incident
Australian Context
An incident in aviation is an event that affects or has the potential to affect the safety of aircraft operations. The ATSB and CASA provide guidance on this definition, including mandatory reporting requirements for occurrences that might endanger aircraft or its occupants.
- Key Elements:
- Incidents are events other than accidents that impact safety.
- Require mandatory reporting if they pose potential safety threats.
- Include issues like loss of separation standards, emergency declarations, or hard landings.
Common Incident Categories
| Category | Examples |
|---|---|
| Aircraft Control | Hard landings, stall warnings |
| Environmental | Birdstrikes, laser interference |
| Ground Operations | Foreign object debris incidents |
| Airspace and Separation | Loss of separation assurance |
| Mechanical | Engine or system failures |
Reporting and Compliance
- Governed by CASA’s alignment with ICAO standards, particularly Annex 19 on Safety Management.
- Incidents are tracked for handling safety trends and enhancing regulatory assessments.
- Information is generally de-identified and shared in adherence to privacy laws under the Freedom of Information Act.
