## Abstract

The FAA is correcting the regulation addressing the effective date of FAA determinations issued under 14 CFR part 77. The FAA amended this regulation by final rule published on July 21, 2010. The purpose of the final rule was to update the regulations governing objects that may affect the navigable airspace, to incorporate case law and legislative action, and to simplify the rule language. In one section of the regulations, we inadvertently state that the effective date of all determinations is 40 days from the date of issuance. However, only FAA determinations subject to the discretionary review process are effective 40 days from the date of issuance. All other FAA determinations are effective upon issuance. This document corrects that error.
