SUMMARY: We are superseding 

Airworthiness Directive (AD) 2013–11– 

14 for certain The Boeing Company 

Model 777–200 and -300 series 

airplanes. AD 2013–11–14 required 

repetitive general visual inspections of 

the strut forward dry bay for the 

presence of hydraulic fluid, and related 

investigative and corrective actions 

(including checking drain lines for 

blockage due to hydraulic fluid coking, 

and cleaning or replacing drain lines to 

allow drainage) if necessary. This AD 

adds airplanes to the applicability. This 

AD was prompted by reports of 

hydraulic fluid contamination 

(including contamination caused by 

hydraulic fluid in its liquid, vapor, and/ 

or solid (coked) form) found in the strut 

forward dry bay. We are issuing this AD 

to detect and correct hydraulic fluid 

contamination of the strut forward dry 

bay, which could result in hydrogen 

embrittlement of the titanium forward 

engine mount bulkhead fittings, and 

consequent inability of the fittings to 

carry engine loads, resulting in engine 

separation. Hydrogen embrittlement 

also could cause a through-crack 

formation across the fittings through 

which an engine fire could breach into 

the strut, resulting in an uncontained 

strut fire. 

DATES: This AD is effective October 22, 

2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of October 22, 2014. 

We must receive any comments on 

this AD by November 21, 2014.

SUPPLEMENTARY INFORMATION: 

Discussion 

On May 24, 2013, we issued AD 

2013–11–14, Amendment 39–17474 (78 

FR 35749, June 14, 2013), for certain 

The Boeing Company Model 777–200 

and -300 series airplanes. AD 2013–11– 

14 required repetitive general visual 

inspections of the strut forward dry bay 

for the presence of hydraulic fluid, and 

related investigative and corrective 

actions (including checking drain lines 

for blockage due to hydraulic fluid 

coking, and cleaning or replacing drain 

lines to allow drainage) if necessary. AD 

2013–11–14 resulted from reports of 

hydraulic fluid contamination 

(including contamination caused by 

hydraulic fluid in its liquid, vapor, and/ 

or solid (coked) form) found in the strut 

forward dry bay. We issued AD 2013– 

11–14 to detect and correct hydraulic 

fluid contamination of the strut forward 

dry bay, which could result in hydrogen 

embrittlement of the titanium forward 

engine mount bulkhead fittings, and 

consequent inability of the fittings to 

carry engine loads, resulting in engine 

separation. Hydrogen embrittlement 

also could cause a through-crack 

formation across the fittings through 

which an engine fire could breach into 

the strut, resulting in an uncontained 

strut fire. 

Actions Since AD 2013–11–14, 

Amendment 39–17474 (78 FR 35749, 

June 14, 2013) was Issued 

Since we issued AD 2013–11–14, 

Amendment 39–17474 (78 FR 35749, 

June 14, 2013), we have received reports 

that a production change installed on 

certain airplanes that would have 

eliminated the need for the inspections 

required by AD 2013–11–14 could not 

be installed; therefore, the inspection of 

these airplanes is now necessary. We are 

issuing this AD to correct the unsafe 

condition on these products. 

Relevant Service Information 

We reviewed Boeing Special 

Attention Service Bulletin 777–54– 

0028, Revision 1, dated December 10, 

2013. For information on the procedures 

and compliance times, see this service 

information at http://

www.regulations.gov by searching for 

Docket No. FAA–2014–0654. 

FAA’s Determination 

We are issuing 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. 

AD Requirements 

Although this AD does not explicitly 

restate the requirements of AD 2013– 

11–14, Amendment 39–17474 (78 FR 

35749, June 14, 2013), this AD retains 

all of the requirements of AD 2013–11– 

14. Those requirements are referenced 

in the service information identified 

previously, which, in turn, is referenced 

in paragraph (g) of this AD. This AD 

continues to require repetitive general 

visual inspections of the strut forward 

dry bay for the presence of hydraulic 

fluid, and related investigative and 

corrective actions (including checking 

drain lines for blockage due to hydraulic 

fluid coking, and cleaning or replacing 

drain lines to allow drainage) if 

necessary, except as discussed under 

‘‘Differences Between this AD and the 

Service Information.’’ This AD also adds 

airplanes to the applicability. 

The phrase ‘‘related investigative 

actions’’ is used in this AD. ‘‘Related 

investigative actions’’ are follow-on 

actions that (1) are related to the 

primary actions, and (2) further 

investigate the nature of any condition 

found. Related investigative actions in 

an AD could include, for example, 

inspections. 

The phrase ‘‘corrective actions’’ is 

used in this AD. ‘‘Corrective actions’’ 

are actions that correct or address any 

condition found. Corrective actions in 

an AD could include, for example, 

repairs. 

Differences Between this AD and the 

Service Information 

Boeing Special Attention Service 

Bulletin 777–54–0028, Revision 1, dated 

December 10, 2013, specifies to contact 

the manufacturer for instructions on 

how to repair certain conditions, but 

this AD would require repairing those 

conditions in one of the following ways: 

• In accordance with a method that 

we approve; or 

• Using data that meet the 

certification basis of the airplane, and 

that have been approved by the Boeing 

Commercial Airplanes Organization 

Designation Authorization (ODA) whom 

we have authorized to make those 

findings. 

FAA’s Justification and Determination 

of the Effective Date 

Since the airplanes added to the 

applicability are not on the U.S. 

Register, notice and opportunity for 

public comment before issuing this AD 

are unnecessary. Therefore, we find that 

notice and opportunity for prior public 

comment are unnecessary and that good 

cause exists for making this amendment 

effective in less than 30 days. 

Comments Invited 

This AD is a final rule that involves 

requirements affecting flight safety, and 

we did not provide you with notice and 

an opportunity to provide your 

comments before it becomes effective. 

However, we invite you to send any 

written data, views, or arguments about 

this AD. Send your comments to an 

address listed under the ADDRESSES

section. Include the docket number 

FAA–2014–0654 and directorate 

identifier 2014–NM–071–AD at the 

beginning of your comments. We 

specifically invite comments on the 

overall regulatory, economic, 

environmental, and energy aspects of 

this AD. We will consider all comments 

received by the closing date and may 

amend this AD 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 AD. 

Costs of Compliance 

We estimate that this AD affects 54 

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 per inspection cycle 5 work-hours × $85 per hour = 

$425 per inspection cycle.

$0 $425 per inspection cycle ....... $22,950 per inspection cycle. 


asabaliauskas on DSK5VPTVN1PROD with RULES
Federal Register / Vol. 79, No. 194 / Tuesday, October 7, 2014 / Rules and Regulations 60333 

Since none of the newly added 

airplanes is on the U.S. Register, the 

requirements of this AD add no 

additional economic burden. 

We estimate the following costs to do 

any necessary actions that would be 

required based on the results of the 

inspection. We have no way of 

determining the number of aircraft that 

might need these actions: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

product 

Detailed inspection ....................................................... 16 work-hours × $85 per hour = $1,360 ...................... $0 $1,360 

Check drain lines (including cleaning or replacing) ..... 5 work-hours × $85 per hour = $425 ........................... $0 $425 

Detailed inspection and high frequency eddy current 

inspection.

16 work-hours × $85 per hour = $1,360 ...................... $0 $1,360 

Clean and restore sealant, primer, and leveling compound.5 work-hours × $85 per hour = $425 ........................... $0 $425 

We have received no definitive data 

that would enable us to provide a cost 

estimate for the on-condition repair 

specified in this AD. 

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. 

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 part 39 of the Federal 

Aviation Regulations (14 CFR part 39) as

■ 2. The FAA amends § 39.13 by 

removing Airworthiness Directive (AD) 

2013–11–14, Amendment 39–17474 (78 

FR 35749, June 14, 2013), and adding 

the following new AD: 

2014–20–10 The Boeing Company: 

Amendment 39–17983; Docket No. 

FAA–2014–0654; Directorate Identifier 

2014–NM–071–AD. 

(a) Effective Date 

This AD is effective October 22, 2014. 

(b) Affected ADs 

This AD replaces AD 2013–11–14, 

Amendment 39–17474 (78 FR 35749, June 

14, 2013). 

(c) Applicability 

This AD applies to The Boeing Company 

Model 777–200 and –300 series airplanes,

hydraulic fluid contamination of the strut 

forward dry bay, which could result in 

hydrogen embrittlement of the titanium 

forward engine mount bulkhead fittings, and 

consequent inability of the fittings to carry 

engine loads, resulting in engine separation. 

Hydrogen embrittlement also could cause a 

through-crack formation across the fittings 

through which an engine fire could breach 

into the strut, resulting in an uncontained 

strut fire. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Inspection 

At the applicable times specified in 

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

ACTION: Final rule; request for 

comments. 

SUMMARY: We are superseding 

airworthiness directive (AD) 2012–02– 

13 for certain Airbus Helicopters, Inc. 

(Airbus Helicopters) Model EC130B4 

helicopters. AD 2012–02–13 required 

inspecting certain areas of the tailboom/ 

Fenestron junction frame (junction 

frame) for a crack. This AD retains the 

requirements of AD 2012–02–13, 

expands the inspection area of the 

junction frame, and reduces the 

repetitive inspection interval. These 

actions are intended to detect a crack in 

the junction frame, which could result 

in detachment of the Fenestron and 

subsequent loss of control of the 

helicopter. 

DATES: This AD becomes effective 

October 22, 2014.
