Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 787–8 

airplanes. This proposed AD was 

prompted by reports of missing bonded 

plugs found prior to airplane delivery, 

during manufacturing inspections, at 

various locations in certain stringers of 

the forward electrical equipment (EE) 

bay of the lower lobe cargo 

compartments. This proposed AD 

would require drilling a hole and 

installing and bonding plugs in certain 

stringers of the forward EE bay of the 

lower lobe cargo compartments. We are 

proposing this AD to detect and correct 

missing or misaligned bonded plugs 

which, in the event of a fire, could cause 

an increased rate of loss of Halon in the 

lower cargo compartments, and result in 

the inability to extinguish a fire and 

consequent loss of control of the 

airplane. 

DATES: We must receive comments on 

this proposed AD by November 7, 2014. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

Discussion 

We have received reports of missing 

bonded plugs found prior to airplane 

delivery, during manufacturing 

inspections, at various locations in 

certain stringers of the forward electrical 

equipment (EE) bay of the lower lobe 

cargo compartments. The cause was 

determined to be miscalculated pressure 

exposures during design. This 

condition, if not corrected, could result 

in missing or misaligned bonded plugs 

which, in the event of a fire, could cause 

an increased rate of loss of Halon in the 

lower cargo compartments, and result in 

the inability to extinguish a fire and 

consequent loss of control of the 

airplane. 

Relevant Service Information 

We reviewed Boeing Alert Service 

Bulletin B787–81205–SB530024–00, 

Issue 001, dated May 15, 2014. For 

information on the procedures and 

compliance times, see this service 

information at http://

www.regulations.gov by searching for 

Docket No. FAA–2014–0649. 

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 

accomplishing the actions specified in 

the service information described 

previously, except as discussed under 

‘‘Differences Between this Proposed AD 

and the Service Information.’’ 

Explanation of ‘‘RC’’ Steps in Service 

Information 

The FAA worked in conjunction with 

industry, under the Airworthiness 

Directives Implementation Aviation 

Rulemaking Committee, to enhance the 

AD system. One enhancement was a 

mstockstill on DSK4VPTVN1PROD with PROPOSALS

Federal Register / Vol. 79, No. 184 / Tuesday, September 23, 2014 / Proposed Rules 56683 

new process for annotating which steps 

in the service information are required 

for compliance with an AD. 

Differentiating these steps from other 

tasks in the service information is 

expected to improve an owner’s/

operator’s understanding of crucial AD 

requirements and help provide 

consistent judgment in AD compliance. 

The actions specified in the service 

information described previously 

include steps that are labeled as RC 

(required for compliance) because these 

steps have a direct effect on detecting, 

preventing, resolving, or eliminating an 

identified unsafe condition. 

As noted in the specified service 

information, steps labeled as RC must be 

done to comply with the proposed AD. 

However, steps that are not labeled as 

RC are recommended. Those steps that 

are not labeled as RC may be deviated 

from, done as part of other actions, or 

done using accepted methods different 

from those identified in the service 

information without obtaining approval 

of an alternative method of compliance 

(AMOC), provided the steps labeled as 

RC can be done and the airplane can be 

put back in a serviceable condition. Any 

substitutions or changes to steps labeled 

as RC will require approval of an 

AMOC. 

Difference Between This Proposed AD 

and the Service Information 

Although Boeing Alert Service 

Bulletin B787–81205–SB530024–00, 

Issue 001, dated May 15, 2014, 

recommends installing and bonding the 

plugs within 24 months, we and Boeing 

have determined a 12-month 

compliance time is appropriate. We 

have advised Boeing to correct the 

compliance time statement in the next 

revision of the service information to 

specify a 12-month compliance time. In 

developing an appropriate compliance 

time for this AD, we considered the 

degree of urgency associated with the 

subject unsafe condition, and the 

average utilization of the affected fleet 

and time necessary to perform the 

installation. In light of these factors, we 

find that a 12-month compliance time 

represents an appropriate interval of 

time for affected airplanes to continue to 

operate without compromising safety. 

Costs of Compliance 

We estimate that this proposed AD 

affects 3 airplanes of U.S. registry. 

We estimate the following costs to 

comply with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product Cost on U.S. operators 

Bonded plug installations ............... 100 work-hours × $85 per hour = $8,500 $3,466 $11,966 Up to $35,898. 

According to the manufacturer, all of 

the costs of this proposed AD may be 

covered under warranty, thereby 

reducing the cost impact on affected 

individuals. We do not control warranty 

coverage for affected individuals. As a 

result, we have included all costs in our 

cost estimate. 

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. 

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.

at various locations in certain stringers of the 

forward electrical equipment (EE) bay of the 

lower lobe cargo compartments. We are 

issuing this AD to detect and correct missing 

or misaligned bonded plugs which, in the 

event of a fire, could cause an increased rate 

of loss of Halon in the lower cargo 

compartments, and result in the inability to 

extinguish a fire and consequent loss of

Revisions to the Arizona State 

Implementation Plan; State Stationary 

Source Rules 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Proposed rule. 

SUMMARY: The Environmental Protection 

Agency (EPA) is proposing to approve 

revisions to the Arizona State 

Implementation Plan (SIP). These 

revisions include two State statutes and 

certain State rules that govern stationary 

sources under the jurisdiction of the 

Arizona Department of Environmental 

Quality and that establish definitions 

and other general provisions; ambient 

air quality standards and area 

designations; and emissions limitations 

and other requirements for certain type 

of stationary sources. Generally, 

approval of these revisions updates and 

replaces previously approved provisions 

in the Arizona SIP, but EPA is also 

approving a few rules that are new to 

the Arizona SIP and a few rescissions 

that remove certain other rules from the 

Arizona SIP without replacement. The 

EPA is approving these revisions 

because they meet all applicable 

requirements of the Clean Air Act (CAA 

or the Act).
