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

ACTION: Final rule; corrections.

-----------------------------------------------------------------------

SUMMARY: The FAA is correcting typographical errors in three existing 
airworthiness directives (ADs) that were published in the Federal 
Register on January 8, 2008 (73 FR 1269); January 7, 2008 (73 FR 1052); 
and January 7, 2008 (73 FR 1055). The errors resulted in incorrect 
docket numbers. One AD applies to all Viking Air Limited Model 
(Caribou) DHC-4 and (Caribou) DHC-4A airplanes. The other two ADs apply 
to all 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. The Viking Air AD requires doing a fluorescent 
penetrant inspection for cracking of certain upper engine mount bracket 
assemblies, and corrective actions if necessary. One of the Boeing ADs 
requires revising the FAA-approved maintenance inspection program to 
include inspections that will give no less than the required damage 
tolerance rating for each structural significant item, and repair of 
cracked structure. The other Boeing AD requires implementing a 
corrosion prevention and control program.

DATES: AD 2008-01-02 is effective January 23, 2008. ADs 2004-07-22 R1 
and 90-25-05 R1 are effective January 22, 2008.

ADDRESSES: You may examine the AD dockets 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 dockets contain 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
