USHST continues to work on the implementation of 16 Helicopter - Safety Enhancements (H-SE) developed through data-driven analysis of 104 fatal accidents.  The H-SE’s use Outreach, Policy, Technology/Equipment, and Training to reduce fatal accidents in these categories.


H-SE 30: Development of Airman Certification Series (ACS) for Rotorcraft

     The FAA will develop the new ACS series for Rotorcraft-Helicopter to replace the Practical Test Standards (PTS) for airman certification. Support from this effort will include diverse expertise from the helicopter community and other industry stakeholders. The new helicopter ACS will contribute to safety by making practical tests meaningful and relevant to actual operations and contribute to the standardization of teaching, learning and testing. 

     The new ACS for helicopter will be designed to communicate the aeronautical knowledge, risk management, and flight proficiency standards for a more integrated and systematic approach to certification of helicopter pilots. This approach will provide both safety risk management and safety assurance processes through which internal and external stakeholders identify and evaluate regulatory changes, safety recommendations and other factors that require modification of airman testing and training materials.
