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 787–8 airplanes. The NPRM 

published in the Federal Register on 

July 30, 2015 (80 FR 45460) (‘‘the 

NPRM’’). The NPRM was prompted by 

a report of fuel leaking onto the hot 

exhaust portion of an engine as a result 

of an unintended leak path from the 

leading edge through the pylon. The 

NPRM proposed to require installing 

new seal dams in the inboard and 

outboard corners of the aft pylon frame 

on the left and right engines, including 

an inspection for damage of the 

outboard blade seal and applicable 

corrective actions. We are issuing this 

AD to prevent fuel leaking from an 

unintended drain path from the leading 

edge through either the left or right 

pylon and onto the hot engine parts or 

brakes, which could lead to a major 

ground fire. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the NPRM and the FAA’s 

response to each comment. United 

Airlines concurred with the content of 

the NPRM. 

Request To Add Revised Service 

Information 

Boeing and All Nippon Airways 

(ANA) asked that we reference Boeing 

Alert Service Bulletin B787–81205– 

SB540004–00, Issue 002, dated 

December 3, 2015, for accomplishing 

the actions in the NPRM. ANA stated 

that there are several errors in the 

referenced service information. Boeing 

stated that a revision would be issued to 

incorporate minor clarifications, and to 

update the effectivity. 

We agree to reference Boeing Alert 

Service Bulletin B787–81205– 

SB540004–00, Issue 002, dated 

December 3, 2015, in this AD. Since we 

published the NPRM, Boeing issued 

Alert Service Bulletin B787–81205– 

SB540004–00, Issue 002, dated 

December 3, 2015. That revision 

removes three airplanes from the 

effectivity, and clarifies certain 

instructions as a result of feedback 

reported by operators after 

incorporation of Boeing Alert Service 

Bulletin B787–81205–SB540004–00, 

Issue 001, dated October 24, 2014. 

Boeing Alert Service Bulletin B787– 

81205–SB540004–00, Issue 001, dated 

October 24, 2014, was specified as the 

appropriate source of service 

information for accomplishing the 

actions in the NPRM. 

We have changed paragraphs (c) and 

(g) of this AD to specify Boeing Alert 

Service Bulletin B787–81205– 

SB540004–00, Issue 002, dated 

December 3, 2015. We have also added 

a new paragraph (h) of this AD to give 

credit for actions done before the 

effective date of this AD using Boeing 

Alert Service Bulletin B787–81205– 

SB540004–00, Issue 001, dated October 

24, 2014; and redesignated subsequent 

paragraphs accordingly. 

Request To Reduce the Compliance 

Time 

The Air Line Pilots Association 

(ALPA) International asked that we 

reduce the compliance time specified in 

the proposed AD (the proposed 

compliance time is within 60 months 

after the effective date of this AD). 

ALPA stated that the severity of a fuel 

leak from the leading edge through the 

pylon and onto the hot exhaust part of 

the engines warrants a shorter 

compliance time to correct this problem. 

We do not agree with the commenter’s 

request to reduce the compliance time. 

In developing an appropriate 

compliance time, we considered the 

safety implications and normal 

maintenance schedules for timely 

installation of inboard and outboard seal 

dams. In consideration of all of these 

factors, we determined that the 

compliance time, as proposed, 

represents an appropriate interval in 

which the inboard and outboard seal 

dams can be installed in a timely 

manner within the fleet, while still 

maintaining an adequate level of safety. 

Most ADs, including this one, permit 

operators to accomplish the 

requirements of an AD at a time earlier 

than the specified compliance time; 

therefore, an operator may choose to 

install the inboard and outboard seal 

dams before the 60-month compliance 

time specified in paragraph (g) of this 

AD. If additional data are presented that 

would justify a shorter compliance time, 

we may consider further rulemaking on 

this issue. 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 AD 

with the changes described previously 

and minor editorial changes. We have 

determined that these minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM for 

correcting 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 AD. 

Related Service Information Under 1 

CFR Part 51 

We reviewed Boeing Alert Service 

Bulletin B787–81205–SB540004–00, 

Issue 002, dated December 3, 2015. This 

service information describes 

procedures for installing new seal dams 

in the inboard and outboard corners of 

the aft pylon frame on the left and right 

engines, doing a general visual 

inspection to detect damage of the 

outboard blade seal, and doing 

corrective actions. 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 17 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this AD: 

mstockstill on DSK4VPTVN1PROD with RULES

Federal Register / Vol. 81, No. 60 / Tuesday, March 29, 2016 / Rules and Regulations 17371 

ESTIMATED COSTS

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

Installation of seal dams ... Up to 22 work-hours × $85 

per hour = $1,870.

Up to $14,611 ................... Up to $16,481 ................... Up to $280,177. 

According to the manufacturer, some 

of the costs of this 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 

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.

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 Airbus Model A330– 

200 and –300 series airplanes; and all 

Model A340–200, –300, –500, and –600 

series airplanes. The NPRM published 

in the Federal Register on November 27, 

2015 (80 FR 74042) (‘‘the NPRM’’). 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA Airworthiness 

Directive 2015–0028R1, dated May 29, 

2015, dated (referred to after this as the 

Mandatory Continuing Airworthiness 

Information, or ‘‘the MCAI’’), to correct 

an unsafe condition for certain Airbus 

Model A330–200 and –300 series 

airplanes; and all Model A340–200, 

–300, –500, and –600 series airplanes. 

The MCAI states: 

Several cases have been reported in which 

the potable water service panel access door 

was lost during flight, causing damage to the 

trimmable horizontal stabilizer. The results 

of subsequent investigations showed that 

these events were due to failure of the 

latching mechanism of the potable water 

service panel access door. 

This condition, if not corrected, could lead 

to further cases of in-flight loss of the potable 

water service panel access door, possibly 

resulting in injury to persons on ground and/ 

or damage to the aeroplane [(e.g., damage to 

the trimmable horizontal stabilizer)]. 

To address this condition, Airbus 

developed a modification and published 

Service Bulletin (SB) A330–52–3086, SB 

A340–52–4094 and SB A340–52–5019, to 

provide instructions for in-service 

accomplishment of that modification. 

Consequently, EASA issued [an] AD * * * 

to require modification of the potable water 

service panel access door 164AR for A330/

A340–200/-300 aeroplanes or 154BR for 

A340–500/-600 aeroplanes, which includes 

installation of reinforced hinge screws and 

more robust latches. 

Since that [EASA] AD was issued, it was 

determined that aeroplanes that have 

embodied Airbus Mod 201938 (Improvement 

of latching mechanism of potable water 

service panel) are also not affected by the 

requirements of this [EASA] AD. 

For the reason described above, this 

[EASA] AD is revised to exclude post-mod 

201938 aeroplanes from the Applicability. 

You may examine the MCAI in the 

AD docket on the Internet at http://

www.regulations.gov by searching for 

and locating Docket No. FAA–2015– 

5815. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM or 

on the determination of the cost to the 

public. 

Conclusion 

We reviewed the relevant data and 

determined that air safety and the 

public interest require adopting this AD 

as proposed except for minor editorial 

changes. We have determined that these 

minor changes:
