AGENCY:

Federal Aviation Administration (FAA), Department of Transportation (DOT).

ACTION:

Final rule; correction.

SUMMARY:

The FAA is correcting typographical errors in an existing airworthiness directive (AD) that was published previously in the Federal Register. The error resulted in two incorrect paragraph references. This AD applies to certain Boeing Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP series airplanes. This AD requires repetitive detailed inspections of the aft pressure bulkhead for indications of “oil cans” and previous oil can repairs at reduced compliance times, and corrective actions if necessary.

DATES:

Effective April 2, 2009.

ADDRESSES:

You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

SUPPLEMENTARY INFORMATION:

On January 29, 2009, the FAA issued AD 2009-04-06, amendment 39-15812 (74 FR 8719, February 26, 2009), for certain Boeing Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP series airplanes. This AD requires repetitive detailed inspections of the aft pressure bulkhead for indications of “oil cans” and previous oil can repairs at reduced compliance times, and corrective actions if necessary.

As published, there are two locations in the AD that reference an incorrect paragraph identifier.

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 April 2, 2009.
