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 certain The Boeing Company 

Model 777–200, –200LR, –300, and 

–300ER series airplanes. The NPRM 

published in the Federal Register on 

February 26, 2018 (83 FR 8199). The 

NPRM was prompted by reports that 

additional areas of BMS 8–39 flexible 

urethane foam were found during a 

routine inspection. The NPRM proposed 

to require an inspection for foam 

insulation on the dripshield above the 

overhead panel support structure and 

replacement if necessary. For certain 

airplanes, the NPRM also proposed to 

require replacement of foam insulation 

on the overhead panel support 

structure. 

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. Boeing and 

United Airlines stated that they 

supported the NPRM. 

Request To Correct a Typo in the 

Service Information 

Delta Airlines (DAL) requested that 

we correct a typo in Boeing Special 

Attention Service Bulletin 777–25– 

0621, Revision 1, dated August 4, 2017. 

DAL stated that during its review of 

Boeing Special Attention Service 

Bulletin 777–25–0621, Revision 1, dated 

August 4, 2017, it found a typo in the 

instructions in step 4 of figures 1 and 3 

in the ‘‘More Data’’ column. DAL stated 

that the instructions refer to Aircraft 

Maintenance Manual (AMM) chapter 

‘‘777 AMM 23–92–02,’’ but the correct 

chapter should be ‘‘777 AMM 23–93– 

02.’’ 

We agree with the commenter that 

there is a typo in Boeing Special 

Attention Service Bulletin 777–25– 

0621, Revision 1, dated August 4, 2017. 

The correct reference should be ‘‘777 

AMM 23–93–02.’’ However, the typo is 

not in an ‘‘RC’’ (required for 

compliance) step in Boeing Special 

Attention Service Bulletin 777–25– 

0621, Revision 1, dated August 4, 2017, 

and the AMM is provided only as a 

reference in Boeing Special Attention 

Service Bulletin 777–25–0621, Revision 

1, dated August 4, 2017. Therefore, we 

have not changed this AD in this regard. 

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting this 

final rule as proposed, 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. 

Related Service Information Under 1 

CFR Part 51 

We reviewed Boeing Special 

Attention Service Bulletin 777–25– 

0621, Revision 1, dated August 4, 2017. 

This service information describes 

procedures for a general visual 

inspection for foam insulation on the 

dripshield above the overhead panel 

support structure and replacement if 

necessary. This service information also 

describes procedures for replacement of 

foam insulation on the overhead panel 

support structure. 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 132 

airplanes of U.S. registry. We estimate 

the following costs to comply with this 

AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Inspection and replacement of foam insulation.Up to 32 work-hours × $85 per hour = 

$2,720.

$5,611 Up to $8,331 .......... Up to $1,099,692 

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 


sradovich on DSK3GMQ082PROD with RULES
31652 Federal Register / Vol. 83, No. 131 / Monday, July 9, 2018 / Rules and Regulations 

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): 

2018–14–02 The Boeing Company: 

Amendment 39–19322; Docket No. 

FAA–2018–0115; Product Identifier 

2017–NM–110–AD. 

(a) Effective Date 

This AD is effective August 13, 2018. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to The Boeing Company 

Model 777–200, –200LR, –300, and –300ER 

series airplanes, certificated in any category, 

as identified in Boeing Special Attention 

Service Bulletin 777–25–0621, Revision 1, 

dated August 4, 2017. 

(d) Subject 

Air Transport Association (ATA) of 

America Code 25, Equipment/furnishings. 

(e) Unsafe Condition 

This AD was prompted by reports that 

additional areas of Boeing Material 

Specification (BMS) 8–39 flexible urethane 

foam were found during a routine inspection 

pursuant to a previously issued AD. The 

degradation of the foam over time increases 

the potential for an uncontrolled fire below 

the passenger compartment floor and other 

locations outside the areas covered by smoke 

detection and fire protection systems. We are 

issuing this AD to address BMS 8–39 flexible 

urethane foam found in certain areas of an 

airplane, which, if exposed to an ignition 

source, could cause loss of control of the 

airplane during a fire. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Inspection and Replacement of Foam 

Installation 

Except as required by paragraph (h) of this 

AD: At the applicable times specified in 

paragraph 1.E., ‘‘Compliance,’’ of Boeing 

Special Attention Service Bulletin 777–25– 

0621, Revision 1, dated August 4, 2017, do 

all applicable actions identified as ‘‘RC’’ 

(required for compliance) in, and in 

accordance with, the Accomplishment 

Instructions of Boeing Special Attention 

Service Bulletin 777–25–0621, Revision 1, 

dated August 4, 2017. 

(h) Exception to Service Information 

Specifications 

For purposes of determining compliance 

with the requirements of this AD: Where 

Boeing Special Attention Service Bulletin 

777–25–0621, Revision 1, dated August 4, 

2017, uses the phrase ‘‘the original issue date 

of this service bulletin,’’ this AD requires 

using ‘‘the effective date of this AD.’’ 

(i) Credit for Previous Actions 

This paragraph provides credit for the 

corresponding actions specified in paragraph 

(g) of this AD, if those actions were 

performed before the effective date of this AD 

using Boeing Special Attention Service 

Bulletin 777–25–0621, dated December 10, 

2014. 

(j) Alternative Methods of Compliance 

(AMOCs) 

(1) The Manager, Seattle 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 (k)(1) of 

this AD. Information may be emailed to: 9- 

ANM-Seattle-ACO-AMOC-Requests@faa.gov.

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 

Commercial Airplanes Organization 

Designation Authorization (ODA) that has 

been authorized by the Manager, Seattle 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) For service information that contains 

steps that are labeled as RC, the provisions 

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

describes in more detail the scope of the 

agency’s authority. This rulemaking is 

promulgated under the authority 

described in Subtitle VII, Part A, 

Subpart I, Section 40103. Under that 

section, the FAA is charged with 

prescribing regulations to assign the use 

of airspace necessary to ensure the 

safety of aircraft and the efficient use of 

airspace. This regulation is within the 

scope of that authority as it amends 

Class E airspace designated as a surface 

area at Iowa County Airport, Mineral 

Point, WI, to support instrument flight 

rules (IFR) operations. 

History 

The FAA published a notice of 

proposed rulemaking in the Federal 

Register (83 FR 9451; March 6, 2018) for 

Docket No. FAA–2018–0087 to amend 

Class E airspace designated as a surface 

area at Iowa County Airport, Mineral 

Point, WI, by changing the airspace to 

full-time and removing the part-time 

status and language from the airspace 

description. Interested parties were 

invited to participate in this rulemaking 

effort by submitting written comments 

on the proposal to the FAA. One 

comment was received supporting the 

proposal with the understanding that 

the change would assist aircraft in the 

terminal environment with obstacle 

avoidance, separation services, and 

noise abatement. The FAA appreciates 

the support for this proposal and 

provides the following for clarification: 

The development of the Class E 

airspace designated as a surface area at 

Iowa County airport takes into 

consideration and provides for terrain 

clearance within the airspace and 

provides for the protection of 

instrument procedures, taking other 

obstacles, such as wind turbines, into 

consideration; however, obstacle 

avoidance is ultimately the 

responsibility of the pilot in command. 

The air traffic services currently 

provided by Chicago ARTCC will be the 

same as previously provided; however, 

those services will now be provided on 

a full-time basis. 

Airspace is not designed nor meant to 

support noise abatement policies. 

Airspace is designed to support air 

traffic services, provide protection for 

and improve the safety of IFR 

operations. Therefore, noise abatement 

policies were not taken into 

consideration in this airspace 

amendment. 

Class E airspace designations are 

published in paragraph 6002 of FAA 

Order 7400.11B, dated August 3, 2017, 

and effective September 15, 2017, which 

is incorporated by reference in 14 CFR 

71.1. The Class E airspace designations 

listed in this document will be 

published subsequently in the Order. 

Availability and Summary of 

Documents for Incorporation by 

Reference 

This document amends FAA Order 

7400.11B, Airspace Designations and 

Reporting Points, dated August 3, 2017, 

and effective September 15, 2017. FAA 

Order 7400.11B is publicly available as 

listed in the ADDRESSES section of this 

document. FAA Order 7400.11B lists 

Class A, B, C, D, and E airspace areas, 

air traffic service routes, and reporting 

points. 

The Rule 

This amendment to Title 14 Code of 

Federal Regulations (14 CFR) part 71 

modifies Class E airspace designated as 

a surface area at Iowa County Airport, 

Mineral Point, WI, by making the 

airspace full-time and removing the 

part-time status language from the 

airspace legal description. This 

amendment is made at the request of 

Chicago ARTCC. 

This action also makes an editorial 

change by removing the name of the city 

associated with the airport in the 

airspace legal description to comply 

with a change to FAA Order 7400.2L, 

Procedures for Handling Airspace 

Matters.
