The Transportation Security Administration delayed the compliance deadline on its separate and controversial rules regarding stringent new security requirements for on-demand air-taxi operators of aircraft with an mtow of 12,500 lb or more. The comment period on the TSA’s proposed Twelve-Five Standard Security Program (TFSSP) was reopened for comments through September 30 and the TSA intends to issue a final rule on October 31. Operators must implement the final security program by December 1. Meanwhile, December 1 is also the deadline for on-demand operators of the Bombardier Global Express, Airbus Corporate Jetliner, Boeing Business Jet and all other private charter aircraft with an mtow of 95,000 lb or more to comply with new airline-like security rules. However, Bombardier is working with the TSA to exempt the Global Express from these rules.
