SUMMARY: The FAA proposes requirements for human space flight of crew and space flight participants as required by the Commercial Space Launch Amendments Act of 2004. If adopted, this rulemaking would establish requirements for crew qualifications, training, and notification. It would also establish training and informed consent requirements for space flight participants. The rulemaking would also modify existing financial responsibility requirements to account for the FAA's new authority for space flight participants and crew, and to issue experimental permits. The experimental permit is the subject of a separate rulemaking. The FAA is conducting this rulemaking in order to fulfill its responsibilities under the new act. The requirements are designed to provide an acceptable level of safety to the general public, and to notify individuals on board of the risks associated with a launch or reentry.
