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 water leakage 

from the potable water system due to 

improperly installed waterline 

couplings, and water leaking into the 

electronics equipment (EE) bays from 

above the floor in the main cabin, 

resulting in water on the equipment in 

the EE bays. This proposed AD would 

require replacing the potable waterline 

couplings above the forward and aft EE 

bays with new, improved couplings. 

This proposed AD would also require 

sealing the main cabin floor areas above 

the aft EE bay, installing drip shields 

and foam blocks, and rerouting the wire 

bundles near the drip shields above the 

equipment in the aft EE bay. We are 

proposing this AD to prevent a water 

leak from an improperly installed 

potable water system coupling, or main 

cabin water source, which could cause 

the equipment in the EE bays to become 

wet, resulting in an electrical short and 

potential loss of system functions 

essential for safe flight. 

DATES: We must receive comments on 

this proposed AD by January 4, 2016. 

ADDRESSES: You may send comments,

Discussion 

We received reports of water leakage 

from the potable water system due to 

improperly installed waterline 

couplings, and water leaking into the EE 

bays from above the floor in the main 

cabin, resulting in water on the 

equipment in the EE bays. Such leakage 

could result in an electrical short and 

potential loss of system functions 

essential for safe flight.

this NPRM. 

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 

‘‘Difference Between this Proposed AD 

and the Service Information.’’ Refer to 

this service information for details on 

the procedures and compliance times. 

Difference Between This Proposed AD 

and the Service Information 

Although Boeing Alert Service 

Bulletin B787–81205–SB530029–00, 

Issue 001, dated March 26, 2015; and 

Boeing Alert Service Bulletin B787– 

81205–SB530031–00, Issue 001, dated 

March 26, 2015, recommend 

accomplishing the sealing of the floors 

and seat tracks, installing drip shields, 

and rerouting adjacent wiring within 24 

months; this proposed AD would 

require accomplishing those actions 

within 60 months. We have determined 

that a 60-month compliance time for 

accomplishing these actions would 

address the unsafe condition in a timely 

manner. 

This compliance time has been 

coordinated with Boeing. 

Explanation of ‘‘RC’’ Steps in Service 

Information 

The FAA worked in conjunction with 

industry, under the Airworthiness 

Directive Implementation Aviation 

Rulemaking Committee (ARC), to 

enhance the AD system. One 

enhancement was a 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 steps identified as RC 

(required for compliance) in any service 

information identified previously have a 

direct effect on detecting, preventing, 

resolving, or eliminating an identified 

unsafe condition. 

For service information that contains 

steps that are labeled as Required for 

Compliance (RC), the following 

provisions apply: (1) 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, and an alternative method of 

compliance (AMOC) is required for any 

deviations to RC steps, including 

substeps and identified figures; and (2) 

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. 

Costs of Compliance 

We estimate that this proposed AD 

affects 17 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 

Replace waterline couplings ............................... Up to 24 work-hours × $85 per hour = up to 

$2,040.

Seal floors and seat tracks ................................. Up to 108 work-hours × $85 per hour = up to 

$9,180.

137 Up to 9,317 Up to 158,389 

Install drip shields and reroute wiring ................. Up to 42 work-hours × $85 per hour = up to 

$3,570.

34,594 Up to 38,164 Up to 648,788 

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.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede 

Airworthiness Directive (AD) 95–18–08, 

for all Airbus Model A300–600 series 

airplanes. AD 95–18–08 currently 

requires repetitive inspections to detect 

cracks in the bottom skin of the wing in 

the area of the cut out for the pylon rear 

attachment fitting, and repair if 

necessary. Since we issued AD 95–18– 

08, we received a report that updated 

fatigue and damage tolerance analyses 

and a fleet survey found that certain 

inspection thresholds and intervals 

must be reduced to allow more timely 

findings of cracking. This proposed AD 

would, for certain airplanes, reduce the 

compliance times for the inspections. 

We are proposing this AD to detect and 

correct such fatigue-related cracking, 

which could result in reduced structural 

integrity of the wing. 

DATES: We must receive comments on 

this proposed AD by January 4, 2016. 

ADDRESSES: You may send comments by 

any of the following methods:
