AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all The 

Boeing Company Model 737–100, –200, 

–200C, –300, –400, and –500 series 

airplanes. This AD was prompted by

on the fuselage frame webs at stations 

forward and aft of the overwing 

emergency exits between stringer-7 

(S–7) and S–8. This AD requires 

repetitive high frequency eddy current 

(HFEC) inspections for cracking of the 

fuselage frame webs at certain stations 

between S–7 and S–8 and applicable oncondition actions. We are issuing this 

AD to address the unsafe condition on 

these products. 

DATES: This AD is effective September 

10, 2018. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of September 10, 2018.

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, and 

–500 series airplanes. The NPRM 

published in the Federal Register on 

May 11, 2018 (83 FR 21946). The NPRM 

was prompted by a report indicating 

that cracks were found on the fuselage 

frame webs at stations forward and aft 

of the overwing emergency exits 

between stringers S–7 and S–8. The 

NPRM proposed to require repetitive 

HFEC inspections for cracking of the 

fuselage frame webs at certain stations 

between S–7 and S–8 and applicable oncondition actions. 

We are issuing this AD to address 

fuselage frame web cracking, which may 

lead to subsequent failure of the 

surrounding structure, and ultimately 

result in rapid decompression and loss 

of structural integrity of the airplane. 

Comments 

We gave the public the opportunity to 

participate in developing this final rule. 

We have considered the comments 

received. The Boeing Company 

Airplanes indicated their support for the 

NPRM. 

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 actions specified in the 

NPRM. 

We concur with the commenter. We 

have redesignated paragraph (c) of the 

proposed AD as paragraph (c)(1) of this 

AD 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 

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. 

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 except for 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

Costs of Compliance 

We estimate that this AD affects 63 

airplanes of U.S. registry. We estimate 

the following costs to comply with this 

AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Action Labor cost Parts cost Cost per product Cost on U.S. operators 

Repetitive inspections ....... Up to 14 work-hours × $85 per hour = 

$1,190 per inspection cycle.

$0 Up to $1,190 per inspection cycle.Up to $74,970 per inspection cycle. 

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 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

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. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new airworthiness 

directive (AD): 

2018–16–09 The Boeing Company 

Airplanes Amendment 39–19349; Docket 

No. FAA–2018–0392; Product Identifier 

2018–NM–044–AD. 

(a) Effective Date 

This AD is effective September 10, 2018. 

(b) Affected ADs 

None. 

(c) Applicability 

(1) This AD applies to all The Boeing 

Company Model 737–100, –200, –200C, 

–300, –400, and –500 series airplanes, 

certificated in any category.

Library/rgstc.nsf/0/EBD1CEC7B301293

E86257CB30045557A?OpenDocument&

Highlight=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 a report 

indicating that cracks were found on the 

fuselage frame webs at stations forward and 

aft of the overwing emergency exits between 

stringer-7 (S–7) and S–8. We are issuing this 

AD to address fuselage frame web cracking, 

which may lead to subsequent failure of the 

surrounding structure, and ultimately result 

in rapid 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

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 

DC–9–81 (MD–81), DC–9–82 (MD–82), 

DC–9–83 (MD–83), and DC–9–87 (MD– 

87) airplanes, Model MD–88 airplanes, 

and Model MD–90–30 airplanes. The 

NPRM published in the Federal 

Register on August 25, 2017 (82 FR 

40505). The NPRM was prompted by a 

report of loss of airspeed indication due 

to icing. The NPRM proposed to require 

modifying the ADH system. We are 

issuing this AD to prevent operation of 

unheated air data sensors in icing 

conditions. Failure to activate the ADH 

system in icing conditions could result 

in irregular airspeed or altitude 

indications, which could possibly result 

in a runway overrun during a high 

speed rejected takeoff (RTO) due to 

failure to rotate before the end of the 

runway, or a stall/overspeed during 

flight. 

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.
