Abstract
This action confirms the effective date of July 25, 2011, for the direct final rule issued June 8, 2011. No comments were received on this final rule. This action amends flight criteria for mitigating against naturally occurring lightning and lightning triggered by the flight of an expendable launch vehicle through or near an electrified environment in or near a cloud. These changes also increase launch availability and implement changes already adopted by the United States Air Force.
