14 CFR Part 39
[Docket No. FAA-2019-0326; Product Identifier 2018-NM-166-AD; Amendment
39-19808; AD 2019-23-14]
RIN 2120-AA64
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 737-100, -200, -200C, -300, -400, and -500 series
airplanes. As published, the service information reference specified in
a certain paragraph of the regulatory text is incorrect. This document
corrects that error. In all other respects, the original document
remains the same.
DATES: This correction is effective January 21, 2020.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of January 21,
2020 (84 FR 68326, December 16, 2019).
ADDRESSES: For service information identified in this final rule,
contact Boeing Commercial Airplanes, Attention: Contractual & Data
Services (C&DS), 2600 Westminster Blvd., MC 110-SK57, Seal Beach, CA
90740-5600; phone: 562-797-1717; internet: https://www.myboeingfleet.com. You may view this referenced service information
at the FAA, Transport Standards Branch, 2200 South 216th St., Des
Moines, WA. For information on the availability of this material at the
FAA, call 206-231-3195. It is also available on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2019-
0326.
Examining the AD Docket
You may examine the AD docket on the internet at https://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 Docket
Operations is Docket 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.
FOR FURTHER INFORMATION CONTACT: Serj Harutunian, Aerospace Engineer,
Propulsion Section, FAA, Los Angeles ACO Branch, 3960 Paramount
Boulevard, Lakewood, CA 90712-4137; phone: 562-627-5254; fax: 562-627-
5210; email: [email protected].
SUPPLEMENTARY INFORMATION: As published, AD 2019-23-14, Amendment 39-
19808 (84 FR 68326, December 16, 2019), requires revising the existing
maintenance or inspection program, as applicable, to include new or
revised airworthiness limitations (AWLs) for all The Boeing Company
Model 737-100, -200, -200C, -300, -400, and -500 series airplanes.
Need for the Correction
As published, the service information reference specified in the
paragraph (g)(2)(ix) of the regulatory text is incorrect. Paragraph
(g)(2)(ix) of the regulatory text incorrectly references the actions
specified in Boeing Service Bulletin 737-28A1228 for the initial
compliance time to accomplish AWL No. 28-AWL-31, ``Cushion Clamps and
Teflon Sleeving Installed on Out-of-Tank Wire Bundles Installed on
Brackets that are Mounted Directly on the Fuel Tanks,'' however, the
correct reference for that initial compliance time is Boeing Service
Bulletin 737-57A1321. Boeing Service Bulletin 737-28A1228 does not
refer to AWL No. 28-AWL-31. AWL No. 28-AWL-31 is only referenced in
Boeing Service Bulletin 737-57A1321.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Boeing 737-100/200/200C/300/400/500 Airworthiness
Limitations (AWLs) and Certification Maintenance Requirements (CMRs),
D6-38278-CMR, dated March 2019. This service information describes AWLs
that include airworthiness limitation instructions (ALI) and critical
design configuration control limitations (CDCCL) tasks related to fuel
tank ignition prevention and the nitrogen generation system. This
service information is reasonably available because the interested
parties have 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
[[Page 2625]]
FAA is publishing the entire rule in the Federal Register.
The effective date of this AD remains January 21, 2020.
Since this action only corrects a reference, 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.
