Under Part 1540, interference with screeners can result in which consequence?

Interference with screeners under Part 1540 is a serious violation that can result in legal action against the individual involved. This regulation is designed to ensure the safety and security of the aviation system, primarily by safeguarding the screeners, who play a critical role in detecting prohibited items and ensuring passenger safety. When an individual obstructs or interferes with a screener's duties, it undermines the security protocols established to protect passengers and crew on flights. Therefore, legal action serves not only as a consequence for the individual but also as a strong deterrent against future infractions.

The other options involve training requirements, reporting obligations, or suspension of duties, which do not address the immediate safety implications of interfering with a screener's work. Legal action is indeed the most appropriate form of response to such conduct, reinforcing the importance of compliance with security processes in aviation.
