AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Bombardier, Inc. Model DHC–8–400 

series airplanes. This AD was prompted 

by fuel system reviews conducted by the 

manufacturer. This AD requires 

replacing a fitting that is part of the 

refuel control solenoid valve assembly. 

We are issuing this AD to prevent 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. 

DATES: This AD becomes effective 

March 17, 2015. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD

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 Bombardier, Inc. Model 

DHC–8–400 series airplanes. The NPRM 

published in the Federal Register on 

March 28, 2014 (79 FR 17459). The 

NPRM was prompted by fuel system 

reviews conducted by the manufacturer. 

The NPRM proposed to require 

replacing a fitting that is part of the 

refuel control solenoid valve assembly. 

We are issuing this AD to prevent 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. 

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 

certain Bombardier, Inc. Model DHC–8– 

400 series airplanes. The MCAI states: 

During the incorporation of Modsum 4– 

126630, mandated by [Canadian] AD CF– 

2010–31 [http://wwwapps3.tc.gc.ca/Saf-SecSur/2/cawis-swimn/images/docacrobat16x16.gif; corresponding 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 [a certain] 

Notice of Proposed Amendment (NPA) 

* * *. 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://

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comment 

received on the NPRM (79 FR 17459, 

March 28, 2014) and the FAA’s response 

to each comment. 

Request To Mandate Only Certain 

Sections of the Service Information 

Horizon Air requested that we revise 

the NPRM (79 FR 17459, March 28, 

2014), to mandate only the section of 

the Accomplishment Instructions that 

corrects the unsafe condition (i.e., 

paragraph 3.B., ‘‘Procedure’’). Horizon 

Air reasoned that paragraph (g) of the 

NPRM mandates the entire 

Accomplishment Instructions of 

Bombardier Service Bulletin 84–28–12, 

Revision A, dated June 20, 2013, and 

that the ‘‘Job Set-Up’’ and ‘‘Close Out’’ 

sections of the Accomplishment 

Instructions do not directly correct the 

unsafe condition. Horizon Air explained 

that requiring the ‘‘Job Set-Up’’ and 

‘‘Close Out’’ sections restricts an 

operator’s ability to perform other 

maintenance in conjunction with the 

incorporation of the service bulletin. As 

an example, Horizon Air suggested that 

an operator might need or want to have 

the gear pins out, but that would not be 

allowed because the NPRM mandates 

the installation of the gear pins through 

the work steps in the ‘‘Job Set-Up’’ 

section, and they cannot be removed 

until the ‘‘Job Close Out’’ section is 

accomplished. 

For the reasons stated by Horizon Air, 

we agree to mandate only the section of 

the Accomplishment Instructions of 

Bombardier Service Bulletin 84–28–12, 


rljohnson on DSK3VPTVN1PROD with RULES
7286 Federal Register / Vol. 80, No. 27 / Tuesday, February 10, 2015 / Rules and Regulations 

Revision A, dated June 20, 2013, that 

corrects the unsafe condition in this AD. 

We have revised paragraph (g) of this 

AD accordingly. 

‘‘Contacting the Manufacturer’’ 

Paragraph in This AD 

Since late 2006, we have included a 

standard paragraph titled ‘‘Airworthy 

Product’’ in all MCAI ADs in which the 

FAA develops an AD based on a foreign 

authority’s AD. 

The MCAI or referenced service 

information in an FAA AD often directs 

the owner/operator to contact the 

manufacturer for corrective actions, 

such as a repair. Briefly, the Airworthy 

Product paragraph allowed owners/

operators to use corrective actions 

provided by the manufacturer if those 

actions were FAA-approved. In 

addition, the paragraph stated that any 

actions approved by the State of Design 

Authority (or its delegated agent) are 

considered to be FAA-approved. 

In the NPRM (79 FR 17459, March 28, 

2014), we proposed to prevent the use 

of repairs that were not specifically 

developed to correct the unsafe 

condition, by requiring that the repair 

approval provided by the State of 

Design Authority or its delegated agent 

specifically refer to this FAA AD. This 

change was intended to clarify the 

method of compliance and to provide 

operators with better visibility of repairs 

that are specifically developed and 

approved to correct the unsafe 

condition. In addition, we proposed to 

change the phrase ‘‘its delegated agent’’ 

to include a design approval holder 

(DAH) with State of Design Authority 

design organization approval (DOA), as 

applicable, to refer to a DAH authorized 

to approve required repairs for the 

proposed AD. 

No comments were provided to the 

NPRM (79 FR 17459, March 28, 2014) 

about these proposed changes. However, 

a comment was provided for an NPRM 

having Directorate Identifier 2012–NM– 

101 AD (78 FR 78285, December 26, 

2013). The commenter stated the 

following: ‘‘The proposed wording, 

being specific to repairs, eliminates the 

interpretation that Airbus messages are 

acceptable for approving minor 

deviations (corrective actions) needed 

during accomplishment of an AD 

mandated Airbus service bulletin.’’ 

This comment has made the FAA 

aware that some operators have 

misunderstood or misinterpreted the 

Airworthy Product paragraph to allow 

the owner/operator to use messages 

provided by the manufacturer as 

approval of deviations during the 

accomplishment of an AD-mandated 

action. The Airworthy Product 

paragraph does not approve messages or 

other information provided by the 

manufacturer for deviations to the 

requirements of the AD-mandated 

actions. The Airworthy Product 

paragraph only addresses the 

requirement to contact the manufacturer 

for corrective actions for the identified 

unsafe condition and does not cover 

deviations from other AD requirements. 

However, deviations to AD-required 

actions are addressed in 14 CFR 39.17, 

and anyone may request the approval 

for an alternative method of compliance 

to the AD-required actions using the 

procedures found in 14 CFR 39.19. 

To address this misunderstanding and 

misinterpretation of the Airworthy 

Product paragraph, we have changed the 

paragraph and retitled it ‘‘Contacting the 

Manufacturer.’’ This paragraph now 

clarifies that for any requirement in this 

AD to obtain corrective actions from a 

manufacturer, the actions must be 

accomplished using a method approved 

by the FAA, the TCCA, or Bombardier, 

Inc.’s TCCA Design Approval 

Organization (DAO). 

The Contacting the Manufacturer 

paragraph also clarifies that, if approved 

by the DAO, the approval must include 

the DAO-authorized signature. The DAO 

Designee signature indicates that the 

data and information contained in the 

document are TCCA-approved, which is 

also FAA-approved. Messages and other 

information provided by the 

manufacturer that do not contain the 

DAO-authorized signature approval are 

not TCCA-approved, unless TCCA 

directly approves the manufacturer’s 

message or other information. 

This clarification does not remove 

flexibility previously afforded by the 

Airworthy Product paragraph. 

Consistent with long-standing FAA 

policy, such flexibility was never 

intended for required actions. This is 

also consistent with the 

recommendation of the Airworthiness 

Directive Implementation Aviation 

Rulemaking Committee to increase 

flexibility in complying with ADs by 

identifying those actions in 

manufacturers’ service instructions that 

are ‘‘Required for Compliance’’ with 

ADs. We continue to work with 

manufacturers to implement this 

recommendation. But once we 

determine that an action is required, any 

deviation from the requirement must be 

approved as an alternative method of 

compliance. 

Other commenters to the NPRM 

having Directorate Identifier 2012–NM– 

101 AD (78 FR 78285, December 26, 

2013) pointed out that in many cases the 

foreign manufacturer’s service bulletin 

and the foreign authority’s MCAI might 

have been issued some time before the 

FAA AD. Therefore, the DOA might 

have provided U.S. operators with an 

approved repair, developed with full 

awareness of the unsafe condition, 

before the FAA AD is issued. Under 

these circumstances, to comply with the 

FAA AD, the operator would be 

required to go back to the 

manufacturer’s DOA and obtain a new 

approval document, adding time and 

expense to the compliance process with 

no safety benefit. 

Based on these comments, we 

removed the requirement that the DAHprovided repair specifically refer to this 

AD. Before adopting such a 

requirement, the FAA will coordinate 

with affected DAHs and verify they are 

prepared to implement means to ensure 

that their repair approvals consider the 

unsafe condition addressed in this AD. 

Any such requirements will be adopted 

through the normal AD rulemaking 

process, including notice-and-comment 

procedures, when appropriate. 

We also have decided not to include 

a generic reference to either the 

‘‘delegated agent’’ or ‘‘DAH with State of 

Design Authority design organization 

approval,’’ but instead we have 

provided the specific delegation 

approval granted by the State of Design 

Authority for the DAH. 

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 (79 FR 

17459, March 28, 2014) for correcting 

the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (79 FR 17459, 

March 28, 2014). 

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 

Bombardier has issued Bombardier 

Service Bulletin 84–28–12, Revision A, 

dated June 20, 2013. The service 

information describes procedures for 

replacing a fitting that is part of the 

refuel control solenoid valve assembly.

Federal Register / Vol. 80, No. 27 / Tuesday, February 10, 2015 / Rules and Regulations 7287 

Costs of Compliance 

We estimate that this AD affects 55 

airplanes of U.S. registry. 

We also estimate that it will take 

about 9 work-hours per product to 

comply with the basic requirements of 

this AD. The average labor rate is $85 

per work-hour. Required parts costs are 

negligible. Based on these figures, we 

estimate the cost of this AD on U.S. 

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 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 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.

ACTION: Final rule; request for 

comments. 

SUMMARY: We are publishing a new 

airworthiness directive (AD) for Airbus 

Helicopters (formerly Eurocopter 

France) Model EC130T2 helicopters, 

which was sent previously to all known 

U.S. owners and operators of these 

helicopters. This AD requires 

repetitively inspecting the attachment 

points where the fan attaches to the 

main gearbox (MGB) oil cooler hopper 

(hopper) and replacing any cracked 

hopper with an airworthy hopper. This 

AD is prompted by several cases of a 

cracked hopper. The cracks were found 

on the hopper at the fan attachment 

points. These actions are intended to 

detect a crack in the hopper at a fan 

attachment point to prevent failure of 

the fan attachment, interference of the 

fan with the control rod of the front 

servo-control or with the flight control 

bellcrank, and subsequent loss of 

control of the helicopter. 

DATES: This AD becomes effective 

February 25, 2015 to all persons except 

those persons to whom it was made 

immediately effective by Emergency AD 

(EAD) 2014–22–51, issued on October 

29, 2014, which contained the 

requirements of this AD. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain document listed in this AD 

as of February 25, 2015. 

We must receive comments on this 

AD by April 13, 2015.

SUPPLEMENTARY INFORMATION: 

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 prior to it becoming effective. 

However, we invite you to participate in 

this rulemaking by submitting written 

comments, data, or views. We also 

invite comments relating to the 

economic, environmental, energy, or 

federalism impacts that resulted from 

adopting this AD. The most helpful 

comments reference a specific portion of 

the AD, explain the reason for any 

recommended change, and include 

supporting data. To ensure the docket 

does not contain duplicate comments, 

commenters should send only one copy 

of written comments, or if comments are 

filed electronically, commenters should 

submit them only one time. We will file 

in the docket all comments that we 

receive, as well as a report summarizing 

each substantive public contact with 

FAA personnel concerning this 

rulemaking during the comment period. 

We will consider all the comments we 

receive and may conduct additional 

rulemaking based on those comments. 

Discussion 

On October 29, 2014, we issued EAD 

2014–22–51, which requires, before 

further flight and thereafter at intervals 

not to exceed 10 hours time-in-service 

(TIS), visually inspecting the hopper for 

a crack at the four attachment points. If 

there is a crack, EAD 2014–22–51 

requires replacing the hopper with an 

airworthy hopper, which is not 

terminating action for the repetitive 

visual inspections. EAD 2014–22–51 

was sent previously to all known U.S. 

owners and operators of these 

helicopters and resulted from several 

cases of a cracked MGB oil cooler 

hopper. 

EAD 2014–22–51 was prompted by 

EAD No. 2014–0229–E, dated October 

20, 2014, issued by EASA, which is the 

Technical Agent for the Member States 

of the European Union, to correct an 

unsafe condition for the Airbus 

Helicopters Model EC130T2 helicopters. 

EASA advises of several cases of 

cracked MGB oil cooler fan attachments 

to the hopper. EASA EAD No. 2014– 

0229–E requires repetitive visual 

inspections of the MGB oil cooler fan 

attachment to the hopper and, 

depending on findings, replacement of 

cracked parts.
