On November 30, 1999 (64 FR 66768), the FAA published a final rule that revised 14 CFR part 91. In the final rule, § 91.215(b)(2) states “* * *from the surface upward to 10,000 MSL* * *” The corresponding text in section 1 of Appendix D should be consistent in describing the altitude as “MSL” but inadvertently was changed from MSL to “above the surface.” Therefore, this action will correct this inconsistency and change the phrase from “above the surface” to “MSL” in section 1 of Appendix D.

As this rule simply corrects an inconsistency in the terminology used to describe altitudes, good cause exists for adopting this amendment without public notice or comment as provided under 5 U.S.C. 553(b). Furthermore, the FAA finds that good cause exists pursuant to 5 U.S.C. 553(d) for making Start Printed Page 61613this rule effective within less than 30 days.
