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 an in-service report of an 

uncommanded and unannunciated nose 

wheel steering during airplane 

pushback from the gate. This AD 

requires installing new cable assemblies 

with a pull-down resistor. We are 

issuing this AD to prevent an 

uncommanded nose wheel steering 

during takeoff or landing in the event of 

an open circuit in the steering system, 

and possible consequent runway 

excursion. 

DATES: This AD becomes effective 

September 29, 2015. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of September 29, 2015.

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 

January 23, 2015 (80 FR 3504). 

The Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian 

Airworthiness Directive CF–2013–38, 

dated November 28, 2013 (referred to 

after this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for certain Bombardier, Inc. Model 

DHC–8–400, –401, and –402 series 

airplanes. The MCAI states: 

There has been one in-service report of an 

un-commanded and un-annunciated nose 

wheel steering during aeroplane push-back 

from the gate. The investigation revealed that 

a design deficiency exists within the steering 

control unit (SCU) where an open circuit may 

not be adequately detected and annunciated 

to the flight crew. A sustained open circuit 

could result in an un-commanded and unannunciated nose wheel steering input. 

Un-commanded nose wheel steering 

during takeoff or landing may lead to a 

runway excursion. 

This [Canadian] AD mandates the 

installation of new cable assemblies, with a 

pull-down resistor, to ensure that the nose 

wheel steering system reverts to fail-safe free 

castor mode in the event of an open circuit 

in the steering system. 

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 (80 FR 3504, 

January 23, 2015) and the FAA’s 

response to each comment. 

Request To Remove Certain Service 

Information Procedures 

Horizon Air requested that we amend 

paragraph (g) of the proposed AD (80 FR 

3504, January 23, 2015) to exclude Part 

A, ‘‘Job Set-up,’’ and Part C ‘‘Close Out,’’ 

sections of the Accomplishment 

Instructions in Bombardier Service 


Lhorne on DSK5TPTVN1PROD with RULES
51460 Federal Register / Vol. 80, No. 164 / Tuesday, August 25, 2015 / Rules and Regulations 

Bulletin 84–32–122, Revision A, dated 

August 28, 2013 Horizon Air stated that 

Part A, ‘‘Job Set-up,’’ and Part C, ‘‘Close 

Out,’’ do not directly correct the unsafe 

condition. Horizon Air explained that 

requiring operators to perform the 

actions in these sections in a specific 

manner restricts the operator’s ability to 

perform other maintenance in 

conjunction with performing the 

corrective action. 

We agree with the commenter’s 

request to exclude the ‘‘Job Set-up’’ and 

‘‘Close Out’’ sections of the 

Accomplishment Instructions of 

Bombardier Service Bulletin 84–32–122, 

Revision A, dated August 28, 2013. We 

have revised paragraph (g) of this AD to 

require accomplishment of only 

paragraph B., ‘‘Procedure,’’ of the 

Accomplishment Instructions of 

Bombardier Service Bulletin 84–32–122, 

Revision A, dated October 4, 2013. 

Conclusion 

We reviewed the relevant data, 

considered the comment received, and 

determined that air safety and the 

public interest require adopting this AD 

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 (80 FR 3504, 

January 23, 2015) for correcting the 

unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (80 FR 3504, 

January 23, 2015). 

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, Inc. has issued Service 

Bulletin 84–32–122, Revision A, dated 

October 4, 2013. This service 

information describes procedures for 

incorporating Bombardier Modification 

Summary (Modsum) 4–126585 to install 

new cable assemblies with a pull-down 

resistor to the pilot hand control and 

rudder pedal potentiometer of the nose 

wheel steering control unit. This service 

information is reasonably available 

because the interested parties have 

access to it through their normal course 

of business or by the means identified 

in the ADDRESSES section of this AD. 

Costs of Compliance 

We estimate that this AD affects 81 

airplanes of U.S. registry. 

We also estimate that it will take 

about 6 work-hours 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 $2,541 per product. Based on 

these figures, we estimate the cost of 

this AD on U.S. operators to be 

$247,131, or $3,051 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. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Bombardier, Inc. Model BD–700–1A10 

and BD–700–1A11 airplanes. This AD 

was prompted by a report of several 

events where pilots experienced 

difficulty in lateral control of the 

airplane after doing a climb through 

heavy rain conditions and a 

determination that the cause was water 

ingress in the aileron control pulley 

assembly. This AD requires, for certain 

airplanes, inspecting for correct 

clearance and rework if necessary, and, 

for certain other airplanes, installing a 

cover for the aileron pulley assembly. 

We are issuing this AD to prevent water 

ingress in the aileron control pulley 

assembly, which could freeze in cold 

conditions and result in reduced control 

of the airplane. 

DATES: This AD becomes effective 

September 29, 2015. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of September 29, 2015.

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 

BD–700–1A10 and BD–700–1A11 

airplanes. The NPRM published in the 

Federal Register on March 30, 2015 (80 

FR 16608). 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian 

Airworthiness Directive CF–2014–23, 

dated July 18, 2014 (referred to after this 

as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for certain Bombardier, Inc. Model BD– 

700–1A10 and BD–700–1A11 airplanes. 

The MCAI states: 

There have been several reports whereby 

pilots have experienced difficulty in lateral 

control following climb through heavy rain 

conditions. In each event, the pilots were 

able to overcome this difficulty without 

disconnecting the aileron control. An 

investigation has determined that the root 

cause of the restricted movement of the 

aileron was due to water ingress into the 

wing root aileron control pulley assembly 

through a gap on the wing-to-fuselage fairing 

resulting in freezing of the aileron control 

system.
