SUMMARY:

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.

SUPPLEMENTARY INFORMATION:

On September 6, 2005, the FAA issued AD 2005-19-06, amendment 39-14271 (70 FR 54474, September 15, 2005), for certain Boeing Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747SR, and 747SP series airplanes; equipped with Pratt & Whitney JT9D-3 and -7 series engines, except JT9D-70 engines. The 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.

As published, the requirements of paragraph (h)(1) of the AD inadvertently reference doing the repetitive replacements “* * * at the applicable compliance time specified in paragraph (h)(1)(i) or (h)(2)(ii) of this AD.” However, there is no paragraph (h)(2)(ii) in the AD. We have removed reference to paragraph (h)(2)(ii) and replaced it with the correct reference to paragraph (h)(1)(ii).

No other part of the regulatory information has been changed; therefore, the final rule is not republished in the Federal Register.

The effective date of this AD remains September 30, 2005.
