SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to all The Boeing Company 
Model 737-100, -200, -200C, -300, -400, -500 series airplanes. The NPRM 
published in the Federal Register on May 25, 2018 (83 FR 24242). The 
NPRM was prompted by the results of a fleet survey that revealed 
cracking in the bulkhead frame web at a certain body station. The NPRM 
proposed to require repetitive inspections of the bulkhead frame web at 
a certain station, and repair if necessary.
    We are issuing this AD to address cracking in the station (STA) 
259.5 bulkhead frame web from the first stiffener above stringer S-10 
to S-13. Such cracking could result in reduced structural integrity of 
the airplane.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. The following presents the comments received on the 
NPRM and the FAA's response to each comment.

Request To Clarify Corrective Actions

    Boeing requested that the Summary section and Related Service 
Information paragraph in the NPRM be revised to clarify that the 
corrective actions include more than just repairs. Boeing stated that 
the service information does not describe defined repairs but indicates 
that if any crack is found, contact Boeing for repair instructions and 
do the repair and repeat the instructions.
    We agree with the commenter's request for the reasons provided by 
the commenter. We have revised the Summary section of this final rule 
by changing ``repair if necessary'' to ``applicable on-condition 
actions.'' We have revised the ``Related Service Information under 1 
CFR part 51'' paragraph of this final rule by clarifying the 
description of the service information to ``. . . low frequency eddy 
current inspections of the STA 259.5 bulkhead frame web from the first 
stiffener above stringer S-10 to S-13, on the left and right sides of 
the airplane and applicable on-condition actions.''

Request To Include Group 1 Airplanes as Specified in the Service 
Information

    Boeing requested that Group 1 airplanes, as specified in Boeing 
Alert Requirements Bulletin 737-53A1369 RB, dated October 12, 2017, be 
addressed in the body of the proposed AD. Boeing stated that this 
change would allow operators with airplanes that are not subject to the 
limit of validity a means to comply with the requirements specified in 
the proposed AD.
    We agree with the commenter's request for the reasons provided by 
the commenter. Group 1 airplanes are those having line numbers 1 
through 291 that have accumulated flight cycles beyond the limit of 
validity of the maintenance program. We have revised paragraph (g) of 
this AD to address Group 1 airplanes, added paragraph (h) of this AD to 
address Group 2 and 3 airplanes, and redesignated the subsequent 
paragraphs accordingly.

Effect of Winglets on Accomplishment of the Proposed Actions

    Aviation Partners Boeing stated that accomplishing the Supplemental 
Type Certificate (STC) ST01219SE does not affect the ability to 
accomplish the actions specified in the NPRM.
    We concur with the commenter. We have redesignated paragraph (c) of 
the proposed AD as (c)(1) and added paragraph (c)(2) to this AD to 
state that installation of STC ST01219SE does not affect the ability to 
accomplish the actions required by this final rule. 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.

[[Page 52136]]

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this final rule with the changes described previously and minor 
editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this final 
rule.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Alert Requirements Bulletin 737-53A1369 RB, 
dated October 12, 2017. The service information describes procedures 
for repetitive high frequency eddy current inspections and low 
frequency eddy current inspections of the STA 259.5 bulkhead frame web 
from the first stiffener above stringer S-10 to S-13, on the left and 
right sides of the airplane and applicable on-condition actions. 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.

Costs of Compliance

    We estimate that this AD affects 411 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:

    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this AD.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. Subtitle VII: Aviation Programs, 
describes in more detail the scope of the Agency's authority.
    We are issuing this rulemaking under the authority described in 
Subtitle VII, Part A, Subpart III, Section 44701: ``General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes and 
associated appliances to the Director of the System Oversight Division.

Regulatory Findings

    This AD will not have federalism implications under Executive Order 
13132. This AD will not have a substantial direct effect on the States, 
on the relationship between the national government and the States, or 
on the distribution of power and responsibilities among the various 
levels of government.
    For the reasons discussed above, I certify that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

List of Subjects in 14 CFR Part 39

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

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

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


Sec.  39.13  [Amended]

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

2018-21-08 The Boeing Company: Amendment 39-19466; Docket No. FAA-
2018-0415; Product 2017-NM-149-AD.

(a) Effective Date

    This AD is effective November 20, 2018.

    (1) This AD applies to all The Boeing Company Model 737-100, -
200, -200C, -300, -400, and -500 series airplanes, certificated in 
any category.
    (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 the results of a fleet survey that 
revealed cracking in the bulkhead frame web at a certain body 
station. We are issuing this AD to address cracking in the station 
(STA) 259.5 bulkhead frame web from the first stiffener above 
stringers S-10 to S-13. Such cracking could result in reduced 
structural integrity of the airplane.
