## Abstract

The FAA is correcting a typographical error in an existing airworthiness directive (AD) that was published in the Federal Register on September 15, 2005 (70 FR 54474). The error resulted in an inadvertent reference to a nonexistent paragraph. This AD applies to certain Boeing Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747- 200C, 747-200F, 747-300, 747SR, and 747SP series airplanes. This AD requires repetitive detailed and ultrasonic inspections of the thrust links of the rear engine mounts for any crack or fracture and corrective actions if necessary.
