We look into the circumstances surrounding an accident on behalf of the Director of Civil Aviation. The most important reason to do that is to learn any lessons the accident may have for the rest of the aviation community. It’s not to blame anyone, or make them liable for what happened.
An investigator might examine the accident scene, gather facts, and review relevant documentation. They work methodically and scientifically using technical expertise. That may take several weeks or even months.
In addition, each investigator is involved in multiple cases at any one time. The overall length of time it takes to complete each investigation is difficult to determine, because each is different. But the final report may not be complete for up to 18 months after the accident.
We assign an Investigator-in-Charge (IIC). As the name suggests, the IIC manages all aspects of the investigation. They may conduct a scene examination, possibly taking photographs and recording details. The IIC will also liaise with police officers and emergency personnel at the site.
Once any scene examination is over, the IIC decides which parts of the aircraft need to be held on to for more analysis. The IIC talks to witnesses, and anyone directly involved with the aircraft. The IIC might also need to talk to family and friends of those involved, to gather information from them. The IIC might also need to get personal documentation from family and friends, like the pilot’s logbook.
The IIC might also ask for help from organisations responsible for meteorology, air traffic control and pathology.
When the investigation is finished, the IIC writes a report for the CAA. Copies of the report will be given to the Director of Civil Aviation, the family, and the coroner. It will then be published on our website to provide safety information to the aviation community.
The IIC is responsible for answering any enquiries, but will be limited in what information they will release to you, or can discuss with you, while the investigation is open.
If you have any information you think might help the investigation, please send it to the IIC or the manager of safety investigations.
