Federal Register / Vol. 79, No. 60 / Friday, March 28, 2014 / Proposed Rules 17459 

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 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. Amend § 39.13 by adding the 

following new airworthiness directive 

(AD): 

The Boeing Company: Docket No. FAA– 

2014–0174; Directorate Identifier 2013– 

NM–212–AD. 

(a) Comments Due Date 

We must receive comments by May 12, 

2014. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to The Boeing Company 

Model 787–8 airplanes, certificated in any 

category, as identified in Boeing Alert 

Service Bulletin B787–81205–SB350001–00, 

Issue 001, dated August 22, 2013. 

(d) Subject 

Air Transport Association (ATA) of 

America Code 35, Oxygen. 

(e) Unsafe Condition 

This AD was prompted by a report that, on 

a different Boeing airplane model, there was 

an oxygen-fed fire, which caused extensive 

damage to the flight deck. We are issuing this 

AD to prevent inadvertent electrical current 

from passing through an internal, anticollapse spring of the low pressure oxygen 

hose, which can cause the low-pressure 

oxygen hose to melt or burn, leading to an 

oxygen-fed fire and/or smoke beneath the 

flight compartment in the forward electronics 

equipment bay. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Rework of Crew Oxygen Distribution 

Manifold Assembly 

For airplanes identified in Boeing Alert 

Service Bulletin B787–81205–SB350001–00, 

Issue 001, dated August 22, 2013: Within 60 

months after the effective date of this AD, 

rework the crew oxygen distribution 

manifold assembly from part number (P/N) 

4421086–101 to P/N 4421086–102, in 

accordance with the Accomplishment 

Instructions of Boeing Alert Service Bulletin 

B787–81205–SB350001–00, Issue 001, dated 

August 22, 2013; and B/E Aerospace Service 

Bulletin 4421086–35–001, Rev. 002, dated 

July 9, 2013; except as specified in paragraph 

(i) of this AD. 

(h) Replacement of Forward Crew Oxygen 

Supply Hose 

For airplanes identified as Group 2 in 

Boeing Alert Service Bulletin B787–81205– 

SB350001–00, Issue 001, dated August 22, 

2013: Within 60 months after the effective 

date of this AD, replace the forward crew 

oxygen supply hose with a new nonconductive forward oxygen supply hose, in 

accordance with the Accomplishment 

Instructions of Boeing Alert Service Bulletin 

B787–81205–SB350001–00, Issue 001, dated 

August 22, 2013. 

(i) Exception to Service Information 

Paragraph III.A., ‘‘Verification,’’ of B/E 

Aerospace Service Bulletin 4421086–35–001, 

Rev. 002, dated July 9, 2013, has a 

typographical error. The last sentence in that 

paragraph states, ‘‘If the decal shows PN 

4421086–101, continue with the retrofit steps 

in paragraph II.B.’’ The sentence should refer 

to paragraph III.B. of B/E Aerospace Service 

Bulletin 4421086–35–001, Rev. 002, dated 

July 9, 2013. 

(j) Parts Installation Prohibition 

As of the effective date of this AD, no 

person may install a distribution manifold 

having B/E Aerospace P/N 4421086–101; a 

flexible supply hose having B/E Aerospace P/ 

N 4421189–016; or a supply hose having 

Boeing P/N 4421189–023; on any airplane. 

(k) Alternative Methods of Compliance 

(AMOCs) 

(1) The Manager, Seattle Aircraft 

Certification Office (ACO), FAA, has the 

authority to approve AMOCs for this AD, if 

requested using the procedures found in 14 

CFR 39.19. In accordance with 14 CFR 39.19,

Discussion 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian 

Airworthiness Directive CF–2013–32, 

dated October 8, 2013 (referred to after 

this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for the specified products. The MCAI 

states: 

During the incorporation of Modsum 4– 

126630, mandated by [Canadian] AD CF– 

2010–31 [FAA AD 2011–13–06, Amendment 

39–16729 (76 FR 37258, June 27, 2011)], it 

has been reported that fitting part number (P/ 

N) 82822074–951 has been installed through 

the rear spar instead of fitting P/N 82822074– 

005 or 82822074–007. Fitting P/N 82822074– 

951 does not comply with the fuel tank safety 

standards introduced in Chapter 525 of the 

Airworthiness Manual through Notice of 

Proposed Amendment (NPA) 2002–043. 

Therefore, this fitting shall be replaced to 

mitigate unsafe conditions that could result 

in a potential ignition source within the fuel 

system. 

This [Canadian] AD mandates the 

replacement of the above-mentioned fittings 

with compliant fittings P/N 82822074–009. 

You may examine the MCAI in the 

AD docket on the Internet at http://

www.regulations.gov by searching for 

and locating it in Docket No. FAA– 

2014–0146. 

The FAA has examined the 

underlying safety issues involved in fuel 

tank explosions on several large 

transport airplanes, including the 

adequacy of existing regulations, the 

service history of airplanes subject to 

those regulations, and existing 

maintenance practices for fuel tank 

systems. As a result of those findings, 

we issued a regulation titled ‘‘Transport 

Airplane Fuel Tank System Design 

Review, Flammability Reduction and 

Maintenance and Inspection 

Requirements’’ (66 FR 23086, May 7, 

2001). In addition to new airworthiness 

standards for transport airplanes and 

new maintenance requirements, this 

rule included Special Federal Aviation 

Regulation No. 88 (‘‘SFAR 88,’’ 

Amendment 21–78, and subsequent 

Amendments 21–82 and 21–83). 

Among other actions, SFAR 88 (66 FR 

23086, May 7, 2001) requires certain 

type design (i.e., type certificate (TC) 

and supplemental type certificate (STC)) 

holders to substantiate that their fuel 

tank systems can prevent ignition 

sources in the fuel tanks. This 

requirement applies to type design 

holders for large turbine-powered 

transport airplanes and for subsequent 

modifications to those airplanes. It 

requires them to perform design reviews 

and to develop design changes and 

maintenance procedures if their designs 

do not meet the new fuel tank safety 

standards. As explained in the preamble 

to the rule, we intended to adopt 

airworthiness directives to mandate any 

changes found necessary to address 

unsafe conditions identified as a result 

of these reviews. 

In evaluating these design reviews, we 

have established four criteria intended 

to define the unsafe conditions 

associated with fuel tank systems that 

require corrective actions. The 

percentage of operating time during 

which fuel tanks are exposed to 

flammable conditions is one of these 

criteria. The other three criteria address 

the failure types under evaluation: 

Single failures, single failures in 

combination with a latent condition(s), 

and in-service failure experience. For all 

four criteria, the evaluations included 

consideration of previous actions taken 

that may mitigate the need for further 

action. 

We have determined that the actions 

identified in this AD are necessary to 

reduce the potential of ignition sources 

inside fuel tanks, which, in combination 

with flammable fuel vapors, could result 

in fuel tank explosions and consequent 

loss of the airplane. 

Relevant Service Information 

Bombardier has issued Service 

Bulletin 84–28–12, Revision A, dated 

June 20, 2013. The actions described in 

this service information are intended to 

correct the unsafe condition identified 

in the MCAI. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with the State of 

Design Authority, we have been notified 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all pertinent 

information and determined an unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Costs of Compliance 

We estimate that this proposed AD 

affects 55 airplanes of U.S. registry. 

We also estimate that it would take 

about 9 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. The cost of 

required parts would be negligible. 

Based on these figures, we estimate the 

cost of this proposed AD on U.S. 


emcdonald on DSK67QTVN1PROD with PROPOSALS
Federal Register / Vol. 79, No. 60 / Friday, March 28, 2014 / Proposed Rules 17461 

operators to be $42,075, or $765 per 

product. 

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.
