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): 

2014–08–09 The Boeing Company:

tkelley on DSK3SPTVN1PROD with RULES
Federal Register / Vol. 79, No. 84 / Thursday, May 1, 2014 / Rules and Regulations 24549 

The Boeing Company Model 777F series 

airplanes. This AD was prompted by a 

report of a fire that originated near the 

first officer’s seat and caused extensive 

damage to the flight deck. This AD 

requires replacing the low-pressure 

oxygen hoses with non-conductive lowpressure oxygen hoses in the stowage 

box and supernumerary ceiling area. We 

are issuing this AD to prevent electrical 

current from passing through an 

internal, anti-collapse spring of the lowpressure oxygen hose, which can cause 

the low-pressure oxygen hose to melt or 

burn and lead to an oxygen-fed fire near 

the flight deck.

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 777F series airplanes. The NPRM 

published in the Federal Register on 

October 23, 2013 (78 FR 63130). The 

NPRM proposed to require replacing the 

low-pressure oxygen hoses with nonconductive low-pressure oxygen hoses 

in the stowage box and supernumerary 

ceiling area in order to prevent electrical 

current from passing through an 

internal, anti-collapse spring of the lowpressure oxygen hose, which can cause 

the low-pressure oxygen hose to melt or 

burn and lead to an oxygen-fed fire near 

the flight deck. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the proposal (78 FR 63130, 

October 23, 2013) and the FAA’s 

response to each comment. 

Support for the NPRM (78 FR 63130, 

October 23, 2013) 

The National Transportation Safety 

Board, The Air Line Pilots Association 

International (ALPA), and Alex Naife 

expressed support for the NPRM (78 FR 

63130, October 23, 2013). 

Request To Shorten Compliance Time 

ALPA recommended that we reduce 

the 36-month compliance time to 

replace the low-pressure oxygen hoses 

to 12 months because of the impact that 

an oxygen-fed fire on the flight deck 

would have on flight safety. 

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, parts availability, 

and normal maintenance schedules for 

timely accomplishment of replacing the 

low-pressure oxygen hoses with nonconductive low-pressure oxygen hoses. 

In consideration of all of these factors, 

we determined that the compliance 

time, as proposed, represents an 

appropriate interval in which the lowpressure oxygen hoses can be replaced 

in a timely manner within the fleet, 

while still maintaining an adequate 

level of safety. 

Also, reducing the compliance time of 

the NPRM (78 FR 63130, October 23, 

2013) would necessitate (under the 

provisions of the Administrative 

Procedure Act) reissuing the notice, 

reopening the period for public 

comment, considering additional 

comments subsequently received, and 

eventually issuing a final rule. In light 

of this, and in consideration of the 

amount of time that has already elapsed 

since issuance of the original notice, we 

have determined that further delay of 

this final rule is not appropriate. 

Operators are permitted to accomplish 

the requirements of an AD at a time 

earlier than the specified compliance 

time; therefore, an operator may choose 

to replace the low-pressure oxygen 

hoses before 36 months after the 

effective date of this final rule. 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 final 

rule in this regard. 

Request for Credit for Previous Actions 

FedEx requested that accomplishment 

of the actions described in Boeing Alert 

Service Bulletin 777–35A0029, dated 

June 6, 2012, be considered as an 

acceptable means of compliance with 

the final rule. (The NPRM (78 FR 63130, 

October 23, 2013) specifies using Boeing 

Alert Service Bulletin 777–35A0029, 

Revision 1, dated April 29, 2013.) FedEx 

commented that Boeing Alert Service 

Bulletin 777–35A0029, Revision 1, 

dated April 29, 2013, on page 12, 

indicates that no more work is required 

for airplanes on which the defective 

hoses were removed, as described in 

Boeing Alert Service Bulletin 777– 

35A0029, dated June 6, 2012. FedEx 

stated that it has already accomplished 

the modification on 5 of its 18 

applicable airplanes, as described in 

Boeing Alert Service Bulletin 777– 

35A0029, dated June 6, 2012. 

We partially agree with the 

commenter. We agree because the 

commenter indicated that the unsafe 

condition has already been removed on 

several of its airplanes. However, 

paragraph (i) of the NPRM (78 FR 63130, 

October 23, 2013), and this final rule 

specifies credit for replacing the 

defective hoses before the effective date 

of this final rule using Boeing Alert 

Service Bulletin 777–35A0029, dated 

June 6, 2012. Therefore, no changes are 

necessary to this final rule in this 

regard. 

Change Made to This Final Rule 

We have revised the unsafe condition 

statement in the SUMMARY, the 

Discussion, and paragraph (e) of this 

final rule to clarify that the unsafe 

condition is near the flight deck, rather 

than on the flight deck. 

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting this AD 


tkelley on DSK3SPTVN1PROD with RULES
24550 Federal Register / Vol. 79, No. 84 / Thursday, May 1, 2014 / Rules and Regulations 

with the change described previously 

and minor editorial changes. We have 

determined that these minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (78 FR 

63130, October 23, 2013) for correcting 

the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (78 FR 63130, 

October 23, 2013). 

Costs of Compliance 

We estimate that this AD affects 18 

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 

Replace oxygen hoses .................................. 7 work-hours × $85 per hour = $595 ............ $1,450 $2,045 $36,810 

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.

for a crack, corrosion, damage, or 

missing cadmium plating in the central 

part of the bolt and, depending on 

findings, a liquid penetrant inspection. 

This AD also requires replacing a 

cracked or damaged bolt. This AD was 

prompted by two reported incidents of 

cracked bolts. The actions of this AD are 

intended to detect an unairworthy bolt 

and prevent failure of a bolt, release of 

a T/R blade, and subsequent loss of 

control of the helicopter. 

DATES: This AD is effective June 5, 2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain documents listed in this AD 

as of June 5, 2014.

SUPPLEMENTARY INFORMATION: 

Discussion 

On November 20, 2013, at 78 FR 

69595, the Federal Register published 

our notice of proposed rulemaking 

(NPRM), which proposed to amend 14 

CFR part 39 by adding an AD that 

would apply to certain Agusta Model 

A109C, A109E, A109K2, and A119 

helicopters. The NPRM proposed to 

require a recurring visual inspection of 

each bolt, part number (P/N) 109–8131– 

09–1, for a crack, corrosion, a nick, 

other damage, or missing cadmium 

plating in the central part of the bolt. If 

a crack is not detected by the visual 

inspection, the NPRM proposed to 

require a liquid penetrant inspection. If 

there is a crack, corrosion, damage, or 

missing cadmium plating in the central 

part of the bolt, the NPRM proposed to 

require replacing the bolt before further 

flight. The NPRM also proposed to 

prohibit installing certain bolts on any 

helicopter unless it has passed the 

proposed inspections. The proposed 

requirements were intended to detect an 

unairworthy bolt and prevent failure of 

a bolt, release of a T/R blade, and 

subsequent loss of control of the 

helicopter. 

The NPRM was prompted by AD No. 

2013–0009, dated January 11, 2013, 

issued by EASA, which is the Technical 

Agent for the Member States of the 

European Union, to correct an unsafe 

condition for Agusta Model A109C, 

A109K2, A109E, and A119 helicopters, 

all serial numbers. EASA advises that 

cracks were reported in bolts, P/N 109– 

8131–09–1, installed on a Model 

A109K2 and a Model A109E helicopter. 

EASA further states that investigations 

conducted by Agusta revealed the 

cracks were in the same area of the bolts 

and corresponded with corrosion pits. 

EASA specified that this condition, if 

not detected and corrected, could cause 

damage to, or loss of, a T/R blade, 

possibly resulting in loss of control of 

the helicopter.
