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. The AD docket contains this AD, the regulatory evaluation, 
any comments received, and other information. The address for the 
Docket Office (telephone 800-647-5527) is the Document Management 
Facility, U.S. Department of Transportation, Docket Operations, M-30, 
West Building Ground Floor, Room W12-140, 1200 New Jersey Avenue, SE., 
Washington, DC 20590.

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.
