Federal Register / Vol. 83, No. 11 / Wednesday, January 17, 2018 / Proposed Rules 2375 

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 proposed 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 to the Director of the 

System Oversight Division. 

Regulatory Findings 

We determined that this proposed AD 

would not have federalism implications 

under Executive Order 13132. This 

proposed AD would 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 this proposed regulation: 

1. Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866; 

2. Is not a ‘‘significant rule’’ under the 

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. 

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 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): 

Bombardier, Inc.: Docket No. FAA–2017– 

1247; Product Identifier 2017–NM–085– 

AD. 

(a) Comments Due Date 

We must receive comments by March 5, 

2018. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Bombardier, Inc., 

Model BD–100–1A10 airplanes, certificated 

in any category, serial numbers 20003 

through 20424 inclusive and 20426 through 

20500 inclusive. 

(d) Subject 

Air Transport Association (ATA) of 

America Code 35, Oxygen. 

(e) Reason 

This AD was prompted by a report 

indicating that certain lanyards for the 

passenger oxygen masks located in the 

airplane’s entry area are too long. The length 

of the oxygen mask lanyard might cause the 

safety pin tethered to the opposite end of the 

lanyard to remain engaged in the oxygen flow 

mechanism when the mask is pulled to the 

passenger’s face. We are issuing this AD to 

detect and correct lanyards that are too long, 

which might result in difficulties starting the 

flow of oxygen in an emergency. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Lanyard Replacement 

Within 36 months after the effective date 

of this AD: For any entry area passenger 

oxygen mask dispensing unit (POMDU) 

having part number (P/N) 833–830–01, 

replace the lanyards in the POMDU with new 

lanyards having P/N 289–65–10, in 

accordance with the Accomplishment 

Instructions of Bombardier Service Bulletin 

100–35–08, dated April 11, 2017. 

(h) Other FAA AD Provisions 

The following provisions also apply to this 

AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, New York ACO 

Branch, FAA, has the authority to approve 

AMOCs for this AD, if requested using the

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. 

(2) Contacting the Manufacturer: For any 

requirement in this AD to obtain corrective 

actions from a manufacturer, the action must 

be accomplished using a method approved 

by the Manager, New York ACO Branch,

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all The 

Boeing Company Model 737–100, –200, 

–200C, –300, –400, and –500 series 

airplanes. This proposed AD was 

prompted by reports of cracks found in 

the main landing gear (MLG) beam 

forward support fitting. This proposed 

AD would require repetitive inspections 

for cracking of the MLG beam forward 

support fitting, and applicable oncondition actions. We are proposing this 

AD to address the unsafe condition on 

these products. 

DATES: We must receive comments on 

this proposed AD by March 5, 2018.

SUPPLEMENTARY INFORMATION: 

Comments Invited 

We invite you to send any written 

relevant data, views, or arguments about 

this proposal. Send your comments to 

an address listed under the ADDRESSES

section. Include ‘‘Docket No. FAA– 

2017–1248; Product Identifier 2017– 

NM–162–AD’’ at the beginning of your 

comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this NPRM. We will consider 

all comments received by the closing 

date and may amend this NPRM 

because of those comments. 

We will post all comments we 

receive, without change, to http://

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact we receive 

about this proposed AD. 

Discussion 

We have received reports indicating 

that a crack was found in the MLG beam 

forward support fitting around the 

fastener locations common to the rear 

spar web, below the upper chord on the 

inboard side of the wing buttock line 

(WBL) 157 rib. Cracks were found on 

airplanes having 62,706 to 65,827 total 

flight hours and 50,152 to 53,039 total 

flight cycles. Because cracks in the MLG 

beam forward support fitting at this 

location are entirely hidden—the 

forward side of the fitting (inside fuel 

tanks) by sealant, and the aft side by the 

rear spar web and MLG beam—they 

cannot be detected reliably during 

normal maintenance and therefore 

require additional inspections. This 

cracking of the MLG beam forward 

support fitting, if not corrected, could 

lead to a fuel leak, the inability of a 

principal structural element to carry 

limit load, or an MLG collapse that 

could prevent continued safe flight and 

landing. 

Related Service Information Under 1 

CFR Part 51 

We reviewed Boeing Alert Service 

Bulletin 737–57A1334, dated September 

26, 2017. The service information 

describes procedures for repetitive high 

frequency eddy current (HFEC) 

inspections for cracking of the MLG 

beam forward support fitting around the 

fastener locations common to the rear 

spar web, below the upper chord on the 

inboard side of the WBL 157 rib, and 

applicable on-condition actions (e.g., 

repair). 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. 

FAA’s Determination 

We are proposing this AD because we 

evaluated all the relevant information 

and determined the unsafe condition 

described previously is likely to exist or 

develop in other products of the same 

type design. 

Proposed AD Requirements 

This proposed AD would require 

accomplishment of the actions 

identified as ‘‘RC’’ (required for 

compliance) in the Accomplishment 

Instructions of Boeing Alert Service 

Bulletin 737–57A1334, dated September 

26, 2017, described previously, except 

for any differences identified as 

exceptions in the regulatory text of this 

proposed AD. 

For information on the procedures 

and compliance times, see this service 

information at http://

www.regulations.gov by searching for 

and locating Docket No. FAA–2017– 

1248. 

Explanation of Applicability 

Model 737 airplanes having line 

numbers 1 through 291 have a limit of 

validity (LOV) of 34,000 total flight 

cycles, and the actions proposed in this 

NPRM, as specified in Boeing Alert 

Service Bulletin 737–57A1334, dated 

September 26, 2017, would be required 

at a compliance time occurring after that 

LOV. Although operation of an airplane 

beyond its LOV is prohibited by 14 CFR 

121.1115 and 129.115, this NPRM 

would include those airplanes in the 

applicability so that these airplanes are 

tracked in the event the LOV is 

extended in the future. 

Costs of Compliance 

We estimate that this proposed AD 

affects 160 airplanes of U.S. registry. We 

estimate the following costs to comply 

with this proposed AD: 


ethrower on DSK3G9T082PROD with PROPOSALS
Federal Register / Vol. 83, No. 11 / Wednesday, January 17, 2018 / Proposed Rules 2377 

ESTIMATED COSTS

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

HFEC inspections ......... Up to 81 work-hours × $85 per hour = Up to 

$6,885 per inspection cycle.

$0 Up to $6,885 per inspection cycle.Up to $1,101,600 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 proposed AD. Because 

the number of work-hours can vary 

widely, depending on the inspection 

findings, these figures were not 

included in the service information. 

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 proposed 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 to the Director of the 

System Oversight Division. 

Regulatory Findings 

We determined that this proposed AD 

would not have federalism implications 

under Executive Order 13132. This 

proposed AD would 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 this proposed regulation: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Is not a ‘‘significant rule’’ under 

the 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. 

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 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): 

The Boeing Company: Docket No. FAA– 

2017–1248; Product Identifier 2017– 

NM–162–AD. 

(a) Comments Due Date 

We must receive comments by March 5, 

2018. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to all The Boeing 

Company Model –100, –200, –200C, –300, 

–400, and –500 series airplanes, certificated 

in any category. 

(d) Subject 

Air Transport Association (ATA) of 

America Code 57, Wings. 

(e) Unsafe Condition 

This AD was prompted by the report of a 

crack indication in the main landing gear 

(MLG) beam forward support fitting on the 

inboard side of the wing buttock line (WBL) 

157 rib, and multiple reports of similar crack 

findings on other airplanes. We are issuing 

this AD to detect and correct cracking of the 

MLG beam forward support fitting on the 

inboard side of the WBL 157 rib. Undetected 

cracks could lead to a fuel leak, the inability 

of a principal structural element to carry 

limit load, or an MLG collapse that could 

prevent continued safe flight and landing. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Required Actions 

(1) For Group 1 airplanes identified in 

Boeing Alert Service Bulletin 737–57A1334, 

dated September 26, 2017: Within 120 days 

after the effective date of this AD, inspect the 

airplane and do all applicable corrective 

actions using a method approved in 

accordance with the procedures specified in 

paragraph (i) of this AD. 

(2) For Group 2 airplanes identified in 

Boeing Alert Service Bulletin 737–57A1334, 

dated September 26, 2017: Except as required 

by paragraph (h) of this AD, at the applicable 

times specified in paragraph 1.E., 

‘‘Compliance,’’ of Boeing Alert Service 

Bulletin 737–57A1334, dated September 26, 

2017, do all applicable actions identified as 

‘‘RC’’ (required for compliance) in, and in 

accordance with, the Accomplishment 

Instructions of Boeing Alert Service Bulletin 

737–57A1334, dated September 26, 2017. 

(h) Exceptions to Service Information 

Specifications 

(1) Where Boeing Alert Service Bulletin 

737–57A1334, dated September 26, 2017, 

uses the phrase ‘‘after the original issue date 

of this service bulletin,’’ for purposes of 

determining compliance with the 

requirements of this AD, the phrase ‘‘after the 

effective date of this AD’’ must be used. 

(2) Where Boeing Alert Service Bulletin 

737–57A1334, dated September 26, 2017, 

specifies contacting Boeing, and specifies 

that action as RC: This AD requires using a 

method approved in accordance with the 

procedures specified in paragraph (i) of this 

AD. 

(i) 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 (j)(1) of 

this AD. Information may be emailed to: 9- 

ANM-LAACO-AMOC-Requests@faa.gov.

notify your appropriate principal inspector, 


ethrower on DSK3G9T082PROD with PROPOSALS
2378 Federal Register / Vol. 83, No. 11 / Wednesday, January 17, 2018 / Proposed Rules 

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 

Commercial Airplanes Organization 

Designation Authorization (ODA) that has 

been authorized by the Manager, Los Angeles 

ACO Branch, 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 (h)(2) 

of this AD: For service information that 

contains steps that are labeled as RC, the 

provisions of paragraphs (i)(4)(i) and (i)(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.

ACTION: Supplemental notice of 

proposed rulemaking (SNPRM); 

reopening of comment period. 

SUMMARY: We are revising an earlier 

proposal to supersede Airworthiness 

Directive (AD) 2014–12–13, which 

applies to all The Boeing Company 

Model 737–100, –200, –200C, –300, 

–400, and –500 series airplanes. The 

first SNPRM proposed to revise the 

proposal by expanding the inspection 

area, and terminating, rather than 

superseding, the requirements of AD 

2014–12–13, after accomplishment of 

the initial inspections. This action 

proposes to again revise the proposal by 

requiring the installation of standardsize fasteners for a certain configuration. 

We are proposing this AD to address the 

unsafe condition on these products. 

Since these actions impose an 

additional burden over that proposed in 

the first SNPRM, we are reopening the 

comment period to allow the public the 

chance to comment on these proposed 

changes. 

DATES: The comment period for the 

SNPRM published in the Federal 

Register on August 11, 2017 (82 FR 

37549), is reopened. 

We must receive comments on this 

SNPRM by March 5, 2018.
