Which item is NOT part of the TSA Enforcement Process?

• A. Letter of Investigation (L.O.I.)
• B. Fines up to $13,000 per occurrence
• C. Civil penalties
• D. Warning letters

Answer: (D)

TSA’s enforcement path is a formal sequence designed to address violations with documented actions, penalties, and opportunities to respond. A Letter of Investigation signals the start of formal review, and if violations are found, the process moves forward with civil penalties that are imposed as fines per occurrence through a formal penalty mechanism. Warning letters are informal notices used to remind about requirements and do not constitute the formal enforcement actions. Therefore, warning letters are not part of the TSA Enforcement Process.
