[Docket No. FAA-2019-0990; Product Identifier 2019-NM-122-AD; Amendment 
39-21156; AD 2020-14-02]

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; correction.

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

SUMMARY: The FAA is correcting an airworthiness directive (AD) that 
published in the Federal Register. That AD applies to all The Boeing 
Company 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. As published, the AD number and Amendment number specified 
in the preamble and regulatory text are incorrect. This document 
corrects that error. In all other respects, the original document 
remains the same.

DATES: This correction is effective July 28, 2020.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of July 28, 
2020 (85 FR 37547, June 23, 2020).

SUPPLEMENTARY INFORMATION: This AD requires repetitive detailed 
inspections and open hole high frequency eddy current (HFEC) 
inspections of the upper splice fittings for cracks and applicable on-
condition actions for all The Boeing Company 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.

Need for the Correction

    As published on June 23, 2020 (85 FR 37547), the AD and Amendment 
numbers for this AD specified in the preamble and regulatory text are 
incorrect. The incorrectly specified AD number was AD 2020-12-10 and 
the incorrectly specified Amendment number was 39-19919; AD number AD 
2020-12-10 is assigned to another AD addressing a Bell Textron Inc. 
helicopter unsafe condition, Amendment 39-21145 (85 FR 35555, June 11, 
2020). The correct AD number for this AD is AD 2020-14-02 and the 
correct Amendment number is 39-21156.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Boeing Alert Requirements Bulletin 747-53A2899 RB, 
Revision 1, dated April 7, 2020. This service information describes 
procedures for repetitive detailed inspections and open hole HFEC 
inspections of the left and right upper splice fittings for cracks and 
applicable on-condition actions. On-condition actions include repair. 
This service information is reasonably available because the interested 
parties have

[[Page 39471]]

access to it through their normal course of business or by the means 
identified in the ADDRESSES section.

Correction of Publication

    This document corrects an error and correctly adds the AD as an 
amendment to 14 CFR 39.13. Although no other part of the preamble or 
regulatory information has been corrected, the FAA is publishing the 
entire rule in the Federal Register.
    The effective date of this AD remains July 28, 2020.
    Since this action only corrects the AD number and amendment number, 
it has no adverse economic impact and imposes no additional burden on 
any person. Therefore, the FAA has determined that notice and public 
comment procedures are unnecessary.

Adoption of the Correction
