Aircraft Accident & Incident Investigations Training Course

Aviation safety has improved largely because the industry investigates accidents and incidents to learn from them, not to assign blame. That work follows a defined international framework and a disciplined method, from securing a site through analyzing recorded data to issuing recommendations that prevent recurrence. This course explains how that process works and the principles behind it.

The focus is on the investigation framework set internationally, the practical conduct of an investigation, the central role of human and organizational factors, and how findings become safety recommendations. It treats investigation as a structured search for causes and contributing factors, governed by the principle that its purpose is prevention, not liability.

Why investigation matters

Accidents are rarely caused by a single failure. They result from chains of contributing factors, often involving people, organizations, and systems as much as hardware. An investigation that stops at the obvious cause, or that turns into a search for someone to blame, misses the deeper lessons and leaves the next accident waiting to happen.

The discipline of investigation is to follow the evidence to all the contributing factors and turn them into recommendations the industry can act on. The separation of investigation from blame is what makes people speak openly, which is what makes the system safer. This course is built around that principle.

What you will be able to do afterwards

By the end of the course, participants should be able to:

Explain the international framework for accident and incident investigation.
Describe how an investigation is prepared and conducted on site.
Recognize the role of human and organizational factors in causation.
Understand how technical and recorded data are analyzed.
Describe how findings become reports and safety recommendations.

Course outline

Unit 1: The investigation framework and principles

The course opens with the framework and its guiding ideas.

The ICAO Annex 13 framework for investigations as reference.
The principle of investigation for prevention, not blame.
Roles of the investigating state and parties involved.
Classifying accidents and incidents.

Unit 2: Investigation preparation and on-site procedures

This unit covers the practical conduct of an investigation.

Notification, readiness, and the go-team.
Securing and documenting the site and wreckage.
Evidence collection and preservation.
Coordination and witness interviews.

Unit 3: Human factors and organizational issues

Most accidents involve human and organizational factors, the focus here.

Human performance and error in causation.
Organizational and systemic contributing factors.
Models for analyzing how failures combine, alongside Human Factors for Airlines, ATC, Airports Staff.
Avoiding hindsight bias in analysis.

Unit 4: Technical and data analysis

This unit covers the evidence from systems and recorders.

Flight data and cockpit voice recorder analysis.
Wreckage and systems examination.
Reconstructing the sequence of events.
Integrating technical and human evidence.

Unit 5: Reporting and safety recommendations

The final unit covers turning findings into prevention.

Structuring the investigation report.
Determining causes and contributing factors.
Writing effective safety recommendations.
Follow-up and acting on recommendations.

How the course is delivered

The course is led through structured explanation, worked examples, and documented investigation case studies. Participants examine investigation reports, factor analyses, and recommendations and discuss the reasoning behind them. The course is educational and builds understanding of the investigation process; it does not authorize anyone to conduct official investigations, which are the responsibility of the relevant state authority.

Who should attend

This course suits aviation safety officers, airline and airport safety staff, regulators and oversight personnel, and aviation professionals who want to understand how investigations work and feed into safety management. It is useful both as an introduction and as a structured view for those who interface with investigations. A general aviation familiarity is helpful but not essential.

Frequently asked questions

Does this course qualify me as an official accident investigator?

No. Official investigations are conducted by the relevant state safety authority and its appointed investigators. This course builds understanding of the framework and method; it does not confer authority to lead an official investigation.

Which framework does the course follow?

It is based on the ICAO Annex 13 framework, which governs the investigation of aircraft accidents and incidents internationally, referenced as subject matter. It explains the principles that apply across states.

Why does the course stress that investigation is not about blame?

Because the purpose of a safety investigation is to prevent recurrence, and treating it as a search for blame discourages the open information that makes the system safer. That principle shapes how the whole process is conducted.
