## Abstract

The FAA is correcting the introductory text in paragraph (a) of Sec. 91.177 that was published on August 18, 1989. The phrase, "or unless otherwise authorized by the Administrator" was inadvertently removed from paragraph (a) introductory text. This action reinstates that phrase with a minor revision.
