SUPPLEMENTARY INFORMATION: AD 2019-15-07, Amendment 39-19700 (84 FR 
41614, August 15, 2019) (``AD 2019-15-07''), requires repetitive 
inspections for cracking of the fuselage lower lobe frames, and 
applicable on-condition actions. That AD also provides an optional 
terminating action for certain repetitive inspections. That AD applies 
to certain The Boeing Company Model 737-100, 737-200, 737-200C, 737-
300, 737-400, and 737-500 series airplanes.

Need for the Correction

    As published, paragraph (h) of the regulatory text of AD 2019-15-07 
contains an error. Paragraph (h) of the AD incorrectly refers to 
paragraph (i) as the Exceptions to Service Information Specifications 
paragraph, and it should have referred to paragraph (j) of the AD.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Boeing Alert Service Bulletin 737-53A1362, dated 
September 20, 2018. The service information describes procedures for 
repetitive inspections for cracking of the fuselage lower lobe frames, 
applicable on-condition actions, and an optional modification of the 
tooling holes and

[[Page 48046]]

insulation attachment holes. On-condition actions include repetitive 
inspections for cracking of the lower lobe frames, repair, and 
repetitive post-repair inspections for cracking.
    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 FAA is publishing the 
entire rule in the Federal Register.
    The effective date of this AD remains September 19, 2019.
    Since this action only corrects paragraph references, 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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

Adoption of the Correction

    Accordingly, pursuant to the authority delegated to me by the 
Administrator, the Federal Aviation Administration amends part 39 of 
the Federal Aviation Regulations (14 CFR part 39) as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13   [Corrected]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2019-15-07 The Boeing Company: Amendment 39-19700; Docket No. FAA-
2019-0023; Product Identifier 2018-NM-145-AD.

(a) Effective Date

    This AD is effective September 19, 2019.

(b) Affected ADs

    None.

(c) Applicability

    (1) This AD applies to The Boeing Company Model 737-100, 737-
200, 737-200C, 737-300, 737-400, and 737-500 series airplanes, 
certificated in any category, as identified in Boeing Alert Service 
Bulletin 737-53A1362, dated September 20, 2018 (``BASB 737-
53A1362'').
    (2) Installation of Supplemental Type Certificate (STC) 
ST01219SE does not affect the ability to accomplish the actions 
required by this AD. Therefore, for airplanes on which STC ST01219SE 
is installed, a ``change in product'' alternative method of 
compliance (AMOC) approval request is not necessary to comply with 
the requirements of 14 CFR 39.17.

(d) Subject

    Air Transport Association (ATA) of America Code 53, Fuselage.

(e) Unsafe Condition

    This AD was prompted by reports of cracks in the frames below 
the passenger floor. The FAA is issuing this AD to address cracks 
that could propagate until the frame severs. Continued operation of 
the airplane with multiple adjacent severed frames, or the 
combination of a severed frame adjacent to fuselage skin chem-mill 
cracks, could result in an uncontrolled decompression and loss of 
structural integrity of the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Required Actions for Group 1 Airplanes

    For airplanes identified as Group 1 in BASB 737-53A1362: Within 
120 days after the effective date of this AD, accomplish actions to 
correct the unsafe condition (e.g., inspections and on-condition 
actions) using a method approved in accordance with the procedures 
specified in paragraph (k) of this AD.

(h) Required Actions for Group 2 Through 20 Airplanes

    For airplanes identified as Group 2 through 20 in BASB 737-
53A1362: Except as specified in paragraph (j) of this AD, at the 
applicable times specified in paragraph 1.E., ``Compliance,'' of 
BASB 737-53A1362, do all applicable actions identified as ``RC'' 
(required for compliance) in, and in accordance with, the 
Accomplishment Instructions of BASB 737-53A1362.

(i) Optional Terminating Action for Certain Repetitive Inspections

    For airplanes identified as Group 2 through 20 in BASB 737-
53A1362, accomplishment of part 13, ``Preventive Modification of the 
Frame Web Tooling Hole and Insulation Attachment Hole in the Section 
46 Lower Lobe Frame,'' in accordance with the Accomplishment 
Instructions of BASB 737-53A1362, terminates the repetitive open 
hole high frequency eddy current inspections required by paragraph 
(h) of this AD, for the modified tooling hole or insulation 
attachment hole location only.

(j) Exceptions to Service Information Specifications

    (1) For purposes of determining compliance with the requirements 
of this AD: Where BASB 737-53A1362 uses the phrase ``the original 
issue date of this service bulletin,'' this AD requires using ``the 
effective date of this AD,'' except where BASB 737-53A1362 uses the 
phrase ``the original issue date of this service bulletin'' in a 
note or flag note.
    (2) Where BASB 737-53A1362 specifies contacting Boeing for 
repair instructions or alternative inspections: This AD requires 
doing the repair, or doing the alternative inspections and 
applicable on-condition actions, using a method approved in 
accordance with the procedures specified in paragraph (k) of this 
AD.

(k) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Los Angeles ACO Branch, FAA, has the authority 
to approve AMOCs for this AD, if requested using the procedures 
found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your 
request to your principal inspector or local Flight Standards 
District Office, as appropriate. If sending information directly to 
the manager of the certification office, send it to the attention of 
the person identified in paragraph (l) of this AD. Information may 
be emailed to: [email protected].
    (2) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the local flight standards district office/certificate holding 
district office.
    (3) An AMOC that provides an acceptable level of safety may be 
used for any repair, modification, or alteration required by this AD 
if it is approved by The Boeing Company Organization Designation 
Authorization (ODA) that has been authorized by the Manager, Los 
Angeles ACO Branch, FAA, to make those findings. To be approved, the 
repair method, modification deviation, or alteration deviation must 
meet the certification basis of the airplane, and the approval must 
specifically refer to this AD.
    (4) Except as required by paragraph (j)(2) of this AD: For 
service information that contains steps that are labeled as Required 
for Compliance (RC), the provisions of paragraphs (k)(4)(i) and 
(k)(4)(ii) of this AD apply.
    (i) The steps labeled as RC, including substeps under an RC step 
and any figures identified in an RC step, must be done to comply 
with the AD. If a step or substep is labeled ``RC Exempt,'' then the 
RC requirement is removed from that step or substep. An AMOC is 
required for any deviations to RC steps, including substeps and 
identified figures.
    (ii) Steps not labeled as RC may be deviated from using accepted 
methods in accordance with the operator's maintenance or inspection 
program without obtaining approval of an AMOC, provided the RC 
steps, including substeps and identified figures, can still be done 
as specified, and the airplane can be put back in an airworthy 
condition.
