39–17445; AD 2013–09–04] 

RIN 2120–AA64 

Airworthiness Directives; Bombardier, 

Inc. Airplanes 

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 reports of chafing found on the main 

landing gear (MLG) yoke. The chafing 

was attributed to contact between the 

nacelle fire detection wires and the 

MLG yoke. This AD requires inspections 

of the nacelle fire detection wires and 

the MLG yoke for damage; replacing 

nacelle fire detection wires, if necessary; 

repairing the MLG yoke, if necessary; 

and installing brackets and associated 

hardware to secure the fire detection 

wires. We are issuing this AD to prevent 

chafing between the nacelle fire 

detection wires and the MLG yoke. 

Chafing could lead to cracking and 

subsequent failure of the MLG yoke, 

which could adversely affect the safe 

landing of the airplane. In addition, 

chafing of the nacelle fire detection 

wires could cause them to fail and 

prevent the detection of a fire in the 

nacelle assembly.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM was published in the Federal 

Register on November 5, 2012 (77 FR 

66413). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The Mandatory Continuing 

Airworthiness Information (MCAI) 

states: 

There have been two (2) in-service reports of 

chafing found on the main landing gear 

(MLG) yoke. The chafing was attributed to 

contact between the nacelle fire detection 

wire and the MLG yoke. This chafing may 

lead to cracking and subsequent failure of the 

MLG yoke. 

Failure of the MLG yoke could adversely 

affect the safe landing of the aeroplane. In 

addition, failure of the fire detection wire 

could prevent the detection of a fire in the 

nacelle assembly. 

This [Canadian] Airworthiness Directive 

(AD) mandates the [detailed] inspection of 

the nacelle fire detection wires and [detailed 

inspection of the] MLG yoke for damage 

[chafing, nicks, cracking] and the installation 

of new brackets to secure the fire detection 

wire to prevent chafing against the MLG yoke 

[and corrective actions if necessary]. 

Corrective actions include replacing 

damaged wires with new wires and 

repairing the MLG yoke. You may 

obtain further information by examining 

the MCAI in the AD docket. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

considered the comments received. 

Request To Allow Reference to 

Canadian AD 

Horizon Air requested that the last 

sentence in paragraph (g)(2)(ii) of the 

NPRM (77 FR 66413, November 5, 2012) 

be deleted. That sentence states, ‘‘The 

approved repair must specifically 

reference this AD.’’ Horizon Air stated 

that Bombardier references Transport 

Canada Civil Aviation ADs on repair 

drawings and the requirement to 

reference an FAA AD has not been 

included in previous ADs issued by the 

FAA. Horizon noted that a reference to 

the Canadian AD should be sufficient 

and the final rule should be changed to 

allow a reference to the Canadian AD. 

For the reasons presented by the 

commenter we agree to delete the last 

sentence of paragraph (g)(2)(ii) in this 

AD. That sentence was inadvertently 

included in the NPRM (77 FR 66413, 

November 5, 2012). 

Request To Change Certain Reference to 

Brackets 

Horizon Air requested that paragraph 

(g)(3) of the NPRM (77 FR 66413, 

November 5, 2012) be revised to delete 

the word ‘‘new’’ from the sentence, 

‘‘Install new brackets and associated 

hardware . . . .’’ Horizon acknowledged 

that this sentence was included in 

Canadian AD CF–2012–15, dated April 

30, 2012, which is referenced in the 

NPRM, but based on the FAA’s policy 

of strict interpretation of the word 

‘‘new’’ as a zero-time part, this sentence 

places an additional requirement on 

U.S. operators to ensure that only zerotime brackets are installed. 

We agree to revise paragraph (g)(3) in 

this final rule to delete the word ‘‘new.’’ 

This will remove the requirement that 

operators only install ‘‘new’’ brackets. 

We also deleted the word ‘‘new’’ in the 

SUMMARY section of this final rule. 

Conclusion 

We reviewed the available data, 

including the comments received, and 

determined that air safety and the 

public interest require adopting the AD 

with the changes described previously 

and minor editorial changes. We have 

determined that these changes: 

• Are consistent with the intent that 

was proposed in the NPRM (77 FR 

66413, November 5, 2012) for correcting 

the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (77 FR 66413, 

November 5, 2012). 

Costs of Compliance 

We estimate that this AD will affect 

80 products of U.S. registry. We also 

estimate that it will take about 3 workhours per product to comply with the 

basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Required parts will cost about $332 per 

product. Where the service information 

lists required parts costs that are 

covered under warranty, we have 

assumed that there will be no charge for 

these parts. As we do not control 

warranty coverage for affected parties, 

some parties may incur costs higher 

than estimated here. Based on these 

figures, we estimate the cost of this AD 

to the U.S. operators to be $46,960, or 

$587 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this AD and placed it in the AD docket.
