The Law Enforcement Assistance Program (LEAP) consists of field investigative and operational activities that support Federal, State, and local agencies by denying anyone who would threaten National Security access to the National Airspace System.

The support provided involves taking regulatory enforcement actions and, as appropriate, providing aviation related support to law enforcement agencies seeking criminal prosecution or conducting airborne drug interdiction. Agents also provide training to law enforcement officers in aviation smuggling techniques and FAA resources.

The LEAP is run by FAA headquarters Office of Investigations, Investigations Division, and Special Agents assigned to regional security divisions, centers and field offices.
