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, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP Series Airplanes
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.

As published, those ADs specify incorrect docket numbers throughout the preamble and regulatory text. Docket numbers are assigned by the Federal Document Management System. We have been informed that incorrect docket numbers were assigned. The correct docket information is provided in the following table.
| AD No. | Original Docket No. | Corrected Docket No. |
|---|---|---|
| AD 2008-01-02 | FAA-2008-0410 | FAA-2007-0410 |

Any commenter who submitted comments to an original, incorrect docket number should check Docket No. FAA-2007-0410, FAA-2007-0411, or FAA 2007-0412 on www.regulations.gov to determine whether the comments have been received and filed in the appropriate docket. If not, or if it is not possible to determine whether comments have been posted to the correct docket, the comments should be resubmitted using the correct docket number.
No other part of the preamble or regulatory information has been changed; therefore, the final rule is not republished in the Federal Register .
