Federal Aviation Administration (FAA), Department of Transportation (DOT).
Final rule; correction.
The FAA is correcting a typographical error in an existing airworthiness directive (AD) that was published in the Federal Register on July 30, 2007 (72 FR 41438). The error resulted in certain compliance times being mislabeled as units of flight cycles instead of flight hours. This AD applies to all Boeing Model 747 airplanes. This AD requires an inspection of the No. 2 and No. 3 windows on the left and right sides of the airplane to determine their part numbers, and related investigative and corrective actions if necessary.
Effective September 21, 2007.
The AD docket contains the proposed AD, comments, and any final disposition. You may examine the AD docket on the Internet at http://dms.dot.gov, or in person at the Docket Operations office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.
