2007-NM-338-AD, 2007-NM-291-AD, and 2007-NM-290-AD; Amendments 39-15325, 39-15326,

Airworthiness Directives; Viking Air Limited Model (Caribou) DHC-4 and (Caribou) DHC-4A


Airplanes; and Boeing Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-

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

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
