ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

originated by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

* * * The pylon internal shear pin was 

found cracked during a regular check. 

Further investigation revealed that the failure 

occurred due to hydrogen embrittlement. The 

ANAC [Ageˆncia Nacional de Aviac ̧a ̃o Civil] 

is issuing this [Brazilian] AD to prevent 

insufficient strength of the pylon to wing 

attachment, which in combination with an 

engine imbalance caused by a fan blade out 

could cause pylon to wing attachment failure 

and consequent engine separation. 

* * * * * 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective 

October 14, 2011. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of October 14, 2011.

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 March 14, 2011 (76 FR 

13539). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

* * * The pylon internal shear pin was 

found cracked during a regular check. 

Further investigation revealed that the failure 

occurred due to hydrogen embrittlement. The 

ANAC is issuing this [Brazilian] AD to 

prevent insufficient strength of the pylon to 

wing attachment, which in combination with 

an engine imbalance caused by a fan blade 

out could cause pylon to wing attachment 

failure and consequent engine separation. 

* * * * * 

Required actions include replacing 

pylon shear pins in the rear outboard 

and inboard shear pin assembly in the 

right- and left-hand pylons with new 

parts. 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 for Further Inspection 

JetBlue requested that, in addition to 

replacement of the pylon rear inboard 

and outboard internal shear pins, a 

detailed visual inspection of the pylon 

rear outboard and inboard external 

shear pins should be done to ensure that 

mstockstill on DSK4VPTVN1PROD with RULES

55784 Federal Register / Vol. 76, No. 175 / Friday, September 9, 2011 / Rules and Regulations 

the external shear pins have no 

evidence of corrosion and corrosion 

products, or corrosion pitting. JetBlue 

found external shear pins with surface 

corrosion and pitting. 

We disagree with the request. Embraer 

inspected the suspect external shear 

pins from JetBlue and found particles of 

sealant and other contaminants 

embedded in the inner surface, but there 

was no sign of corrosion or damage. The 

material of the external shear pin is 

corrosion-resistant stainless steel. No 

change has been made to the AD in this 

regard. 

Request To Clarify Service Bulletin 

Reference 

Embraer requested that paragraph (j) 

of the NPRM refer to EMBRAER Service 

Bulletin 190LIN–54–0001, dated June 

21, 2010, rather than 190LIN–54–001. 

We agree with the request and have 

made the change in paragraph (j) of this 

AD. 

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 change described previously. 

We determined that this change will not 

increase the economic burden on any 

operator or increase the scope of the AD. 

Differences Between This AD and the 

MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 

general, agree with their substance. But 

we might have found it necessary to use 

different words from those in the MCAI 

to ensure the AD is clear for U.S. 

operators and is enforceable. In making 

these changes, we do not intend to differ 

substantively from the information 

provided in the MCAI and related 

service information. 

We might also have required different 

actions in this AD from those in the 

MCAI in order to follow our FAA 

policies. Any such differences are 

highlighted in a NOTE within the AD. 

Costs of Compliance 

We estimate that this AD will affect 

73 products of U.S. registry. We also 

estimate that it will take about 10 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 $2,360 

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 

$234,330, or $3,210 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 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); and 

3. 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. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Operations office between 9 a.m. 

and 5 p.m., Monday through Friday, 

except Federal holidays. The AD docket 

contains the NPRM, the regulatory 

evaluation, any comments received, and 

other information. The street address for 

the Docket Operations office (telephone 

(800) 647–5527) is in the ADDRESSES

section. Comments will be available in 

the AD docket shortly after receipt.

products listed above. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

originated by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

Several operators have reported pitch 

oscillations and/or elevator asymmetry

the autopilot engaged. Investigations revealed 

that loose rivets in the torque tube assemblies 

caused relative motion between the crank 

arms and torque tubes. 

Loose rivets could result in excessive wear 

and subsequent significant backlash in the 

driving crank arms. This condition, if left 

uncorrected, will progressively get worse and 

degrade the controllability of the aeroplane. 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products.
