Twelve-Five Standard Security Program
The current Twelve-Five Standard Security Program (TFSSP) rules require aircraft operators of aircraft with a maximum certificated takeoff weight (MTOW) of more than 12,500 pounds conduct criminal background checks on their flight crew members, and restrict access to the flight deck. The operations affected are typically conducted under Federal Aviation Regulation (FAR) Part 135 and are frequently referred to as "charter" flights.
TFSSP Requirements from TSA
On February 22, 2002, the Transportation Security Administration (TSA) published in the Federal Register a Final Rule that required, "certain aircraft operators using aircraft with a maximum certificated takeoff weight of 12,500 pounds or more to carry out security measures." The rule also requires, "certain aircraft operators conduct criminal history records checks (CHRC) on their flight crew members, and restrict access to the flight deck."
TSA defines "Certain aircraft operators" as those conducting operations "in scheduled or charter service, carrying passengers or cargo, or both…" The program that outlines the security measures and requirements for these operators is known as the Twelve-Five Standard Security Program (TFSSP).
