# Application.
**AGENCY:**
Federal Aviation Administration (FAA), DOT.
**ACTION:**
Final rule; correction.
**SUMMARY:**
This document makes two minor corrections to a final rule that amends commercial space transportation regulations governing the launch of expendable launch vehicles. 71 FR 50507 (Aug. 25, 2006). This action is necessary to correct a paragraph designation and add a notation of a reserved appendix. This correction does not make substantive changes to the final rule.
**EFFECTIVE DATES:**
September 25, 2006.

**SUPPLEMENTARY INFORMATION:**
**Background**
In the August 25, 2006, final rule (71 FR 50507, 50531), amendatory instruction no. 6 added paragraph (d), *Measurement system consistency* to 14 CFR 413.7. However, an earlier FAA action had added paragraph (d), *Safety approval* to § 413.7. 71 FR 46847, 46852 (Aug. 15, 2006). It was not the FAA's intention in the August 25, 2006 rule to supersede the previously added paragraph (d). Thus, we are changing the paragraph designation of *Measurement system consistency* to 14 CFR 413.7(e).
Also, in the August 25, 2006 rule, amendatory instruction no. 21 added 14 CFR part 417 in its entirety. 71 FR at 50537. The table of contents for the part indicated that appendix F was reserved for future use. However, the text of part 417 inadvertently failed to include any reference to the existence of the reserved appendix. To avoid any possible confusion, we are adding a notation referencing the reserved appendix between the text of appendix E of part 417 and the text of appendix G of part 417.
**Justification for Expedited Rulemaking**
Section 553 of the Administrative Procedure Act, 5 U.S.C. 553(b)(B), provides that, when an agency for good cause finds that notice and public procedure are impracticable, unnecessary, or contrary to the public interest, the agency may issue a rule without providing notice and an opportunity for public comment. We have determined there is good cause for making today's action final without prior proposal and opportunity for comment because the changes are minor technical corrections and do not change the substantive requirements of the rule. Thus, notice and public procedure are unnecessary.
