Who is primarily responsible for the safety of the aircraft site after an accident?

The captain of the aircraft is primarily responsible for the safety of the aircraft site after an accident. This is rooted in the principle that the pilot in command is ultimately responsible for the safety and security of the aircraft and everyone on board. In the event of an accident, the captain's duties extend to ensuring that the scene is safe, managing any hazards, preventing unauthorized access, and safeguarding evidence for further investigation.

While other entities like the Ministry of Transportation, the TSB investigation team, and the regional aviation authority play important roles in accident investigations and overall aviation safety, their involvement typically comes after the initial duties of the captain have been addressed. The captain's role is crucial in the immediate aftermath of an accident to maintain safety and order at the crash site.
