ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for British 

Aerospace Regional Aircraft Jetstream 

Series 3101 and Jetstream Model 3201 

airplanes. This AD results from 

mandatory continuing airworthiness 

information (MCAI) issued 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 stress 

corrosion cracking of the main landing 

gear yoke pintle housing on a Jetstream 

series 3100 airplane. We are issuing this 

AD to require actions to address the 

unsafe condition on these products. 

DATES: This AD is effective May 2, 2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of May 2, 2014.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to add an AD that would apply 

to British Aerospace Regional Aircraft 

Jetstream Series 3101 and Jetstream 

Model 3201 airplanes. That NPRM was 

published in the Federal Register on 

December 3, 2013 (78 FR 72598). That 

NPRM proposed to correct an unsafe 

condition for the specified products. 

The MCAI states: 

An occurrence of Jetstream 3100 main 

landing gear (MLG) failure after landing was 

reported. The subsequent investigation 

revealed stress corrosion cracking of the MLG 

yoke pintle housing as a root cause of the 

MLG failure. Degradation of the surface 

protection by abrasion can occur when the 

forward face of the yoke pintle rotates against 

the pintle bearing, which introduces 

corrosion pits and, consequently, stress 

corrosion cracking. 

This condition, if not corrected, could lead 

to structural failure of the MLG possibly 

resulting in loss of control of the aeroplane 

during take-off or landing runs. 

To address this potential unsafe condition, 

BAE Systems (Operations) Ltd issued Service 

Bulletin (SB) 32–JM7862 to provide 

instruction for installation of a protective 

washer fitted at the forward spigot on both, 

left hand (LH) and right hand (RH), MLG. 

For the reasons described above, this 

AD requires installation of a washer to 

protect the MLG at the forward face of 

the yoke pintle. The MCAI can be found 

in the AD docket on the Internet at: 

http://www.regulations.gov/

#!documentDetail;D=FAA-2013-1012- 

0002. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (78 

FR 72598, December 3, 2013) or on the 

determination of the cost to the public. 

Conclusion 

We reviewed the relevant data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed except for minor editorial 

changes. We have determined that these 

minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (78 FR 

72598, December 3, 2013) for correcting 

the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (78 FR 72598, 

December 3, 2013). 


tkelley on DSK3SPTVN1PROD with RULES
17396 Federal Register / Vol. 79, No. 60 / Friday, March 28, 2014 / Rules and Regulations 

Costs of Compliance 

We estimate that this AD will affect 

66 products of U.S. registry. We also 

estimate that it would take about 15 

work-hours per product to comply with 

the basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Based on these figures, we estimate 

the cost of this AD on U.S. operators to 

be $84,150, or $1,275 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), 

(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. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http://www.

regulations.gov by searching for and 

locating it in Docket No. FAA–2013– 

1012; or in person at the Docket 

Management Facility 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 Office (telephone (800) 647– 

5527) is in the ADDRESSES section.

Safety. 

Adoption of the Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 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. The FAA amends § 39.13 by adding 

the following new AD: 

2014–06–03 British Aerospace Regional 

Aircraft: Amendment 39–17807; Docket 

No. FAA–2013–1012; Directorate 

Identifier 2013–CE–037–AD. 

(a) Effective Date 

This airworthiness directive (AD) becomes 

effective May 2, 2014. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to British Aerospace 

Regional Aircraft Jetstream Series 3101 and 

Jetstream Model 3201 airplanes, all serial 

numbers, certificated in any category. 

(d) Subject

(e) Reason 

This AD was prompted by 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 stress 

corrosion cracking of the main landing gear 

yoke pintle housing. We are issuing this AD 

to prevent abrasion and subsequent corrosion 

from building on the main landing gear 

(MLG) yoke pintle housing. This condition if 

not corrected could cause structural failure of 

the MLG resulting in loss of control during 

take-off or landing. 

(f) Actions and Compliance 

Unless already done, do the following 

actions as applicable in paragraphs (f)(1) and 

(f)(2) of this AD: 

(1) At the next scheduled MLG removal 

after May 2, 2014 (the effective date of this 

AD), modify the left hand (LH) and right 

hand (RH) MLG installation at the forward 

spigot following the accomplishment 

instructions of British Aerospace Jetstream 

Series 3100 & 3200 Service Bulletin 32– 

JM7862, Revision 1, dated May 7, 2013. 

(2) As of May 2, 2014 (the effective date of 

this AD), do not install any LH or RH MLG 

on Jetstream Series 3101 airplanes and 

Jetstream Model 3201 airplanes unless it is 

found to be in compliance with the 

requirements of paragraph (f)(1) of this AD. 

(g) Credit for Actions Done in Accordance 

With Previous Service Information 

This AD allows credit for the requirements 

of paragraph (f)(1) of this AD if already done 

before May 2, 2014 (the effective date of this 

AD), following British Aerospace Jetstream 

Series 3100 & 3200 Service Bulletin SB 32– 

JM7862, original issue, dated April 8, 2013.

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 Rockwell Collins TPR– 

720 and TPR–900 Mode select (S) 

transponders that are installed on 

airplanes. The NPRM published in the 

Federal Register on November 19, 2013 

(78 FR 69318). The NPRM proposed to 

require testing and calibration of the 

alignment of the TPR–720 and TPR–900 

Mode S transponders. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the proposal and the FAA’s 

response to each comment. 

Request FAA Review Impact on AD 92– 

11–09 (57 FR 20744, May 15, 1992) 

Konstantinos Sideris of Airbus 

commented that AD 92–11–09 (57 FR 

20744, May 15, 1992) required 

converting part number (P/N) 622– 

7878–020 into P/N 622–7878–301. The 

commenter stated that the proposed AD 

would affect both of those P/Ns, and he 

requested the FAA review the impact of 

the proposed AD on AD 92–11–09 and 

consider cancelling AD 92–11–09. 

After review, we disagree with 

cancelling AD 92–11–09 (57 FR 20744, 

May 15, 1992). This AD requires a 

different task than that required in AD 

92–11–09 and assures timely test and 

calibration for all affected P/Ns, 

including those affected and referenced 

in AD 92–11–09. 

We did not change the final rule AD 

action based on this comment. 

Request FAA Add and Delete Specific 

Model Airplanes from Applicability 

The Boeing Company requested we 

add Models 737 classics, 737NG, 757, 

and 767 airplanes to the Applicability 

and exclude the Model 747–8. 

We agree that this AD may apply to 

Models 737, 757, and 767 airplanes; 

however, paragraph (c), Applicability, of 

this AD is not intended as all-inclusive. 

Paragraph (c) of this AD states, ‘‘. . . 

transponders that are installed on but 

not limited to the airplanes . . .’’ and 

gives a partial listing of airplanes known 

to have the affected transponders 

installed. In our discussions with 

Rockwell Collins, they discussed that 

the subject transponders may be 

installed by supplemental type 

certificate on models other than the 

models that are known to have the 

affected transponders installed. 

We added language to paragraph (c), 

Applicability, to clarify that the listing 

of airplanes is not all-inclusive. 

Request FAA Change the Cost of 

Compliance Estimate 

The Boeing Company requested we 

adjust the total estimated cost of 

compliance to account for the added 

airplane models the commenter 

requested we add. 

We disagree with this comment. We 

based the estimated cost of compliance 

on the number of transponder units 

produced by Rockwell Collins, not the 

estimated number of airplanes that may 

have the transponders installed. 

We did not change the final rule AD 

action based on this comment. 

Request FAA Change the Language of 

the Required Action 

Craig Amadeo of Delta Airlines 

requested we change the language in the 

AD to clarify that the operators do not 

have to return the transponders to 

Rockwell Collins for the testing and 

calibration. Delta has full capability to 

test and align the receiver of the affected 

transponders. The commenter also 

requested we add more specific
