Launch Safety: Lightning Criteria for Expendable Launch Vehicles

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Direct final rule; Confirmation of effective date.

SUMMARY: 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.

DATES: The direct final rule published June 8, 2011 (76 FR 33139) is effective on July 25, 2011.

SUPPLEMENTARY INFORMATION:

Direct Final Rule Procedure

The FAA anticipated that this regulation would not result in adverse or negative comment and therefore is issued as a direct final rulemaking. Because the changes to the lightning commit criteria will increase launch availability and are already for U.S. Government launchs at Air Force launch ranges, the public interest is well served by this rulemaking.

The comment period closed July 8, 2011, and the FAA received no comments.

Conclusion

In light of the fact that no comments were submitted in response to the direct final rule, the FAA has determined that no further rulemaking action is necessary. Therefore, Amendment No. 417-2 takes effect as of July 25, 2011.
