Do preflight inspections need to be completed before passengers board?

Preflight inspections must be completed before passengers board the aircraft to ensure safety and compliance with aviation regulations. These inspections are crucial for identifying any potential issues with the aircraft, such as mechanical failures, fuel levels, or equipment functionality, which could pose risks to the safety of passengers and crew. Ensuring that the aircraft is fully operational before loading passengers is a fundamental aspect of aviation safety protocols. Skipping or not performing these inspections could endanger lives and violate regulatory standards upheld by aviation authorities. Therefore, the stance that preflight inspections are always required reflects the industry's commitment to safety and regulatory compliance.
