Airworthiness Directives; BAE 

Systems (Operations) Limited Model 

Avro 146–RJ and BAe 146 Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

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: 

A potential fleet wide problem has been 

identified regarding the interchanging of 

wing links on all BAe 146 & AVRO 146–RJ 

aircraft during scheduled maintenance. Some 

operators erroneously believed that these 

parts were interchangeable. The effects of 

changing winglinks has resulted in either a 

shorter or longer wing link being fitted, 

which introduces local stresses in the wing 

top and bottom surfaces local to rib 2, wing 

links and wing link fitting attachment and 

the fuselage local to Frames 26 and 29. This 

condition, if not corrected, could result in a 

reduction of structural integrity of the 

fuselage/wing attachment with possible 

catastrophic consequences. 

* * * * * 

The unsafe condition could result in 

loss of a wing or controllability of the 

airplane. We are issuing this AD to 

require actions to correct the unsafe 

condition on these products. 

DATES: This AD becomes effective 

September 17, 2010. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of September 17, 2010.

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 15, 2010 (75 FR 

12158). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

A potential fleet wide problem has been 

identified regarding the interchanging of 

wing links on all BAe 146 & AVRO 146–RJ 

aircraft during scheduled maintenance. Some 

operators erroneously believed that these 

parts were interchangeable. The effects of 

changing winglinks has resulted in either a 

shorter or longer wing link being fitted, 

which introduces local stresses in the wing 

top and bottom surfaces local to rib 2, wing 

links and wing link fitting attachment and 

the fuselage local to Frames 26 and 29. This 

condition, if not corrected, could result in a 

reduction of structural integrity of the 

fuselage/wing attachment with possible 

catastrophic consequences. 

For the reasons described above, the 

present Airworthiness Directive (AD) 

requires the accomplishment of inspections 

and rectification actions, as necessary. 

The unsafe condition could result in 

loss of a wing or controllability of the 

airplane. The inspections include 

inspecting wing links for incorrect part 

numbers (i.e., parts that are not 

original), inspecting to determine wing 

geometry measurements, and inspecting 

the wing link, bores, bolts, and nuts for 

corrosion. Corrective actions include 

installing wing-to-fuselage fairings and 

repairing. 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 

received no comments on the NPRM or 

on the determination of the cost to the 

public. 

Explanation of Change to Applicability 

We have revised the applicability in 

paragraph (c) of this final rule to 

identify model designations as 

published in the most recent type 

certificate data sheet for the affected 

models. 

Conclusion 

We reviewed the available data 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 


erowe on DSK5CLS3C1PROD with RULES
49378 Federal Register / Vol. 75, No. 156 / Friday, August 13, 2010 / Rules and Regulations 

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 1 

product of U.S. registry. We also 

estimate that it will take about 180 

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 $0 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 $15,300. 

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.

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: 

2010–16–10 BAE Systems (Operations) 

Limited: Amendment 39–16387. Docket 

No. FAA–2010–0222; Directorate 

Identifier 2008–NM–012–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective September 17, 2010. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to BAE Systems 

(Operations) Limited Model BAe 146–100A, 

–200A, and –300A airplanes, and Avro 146– 

RJ70A, 146–RJ85A, and 146–RJ100A 

airplanes; all serial numbers; certificated in 

any category; as identified in paragraph 

1.A.(1) of BAE Systems (Operations) Limited 

Inspection Service Bulletin ISB.53–175, 

Revision 1, dated April 2, 2007. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 57: Wings. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

A potential fleet wide problem has been 

identified regarding the interchanging of 

wing links on all BAe 146 & AVRO 146–RJ 

aircraft during scheduled maintenance. Some 

operators erroneously believed that these 

parts were interchangeable. The effects of 

changing wing links has resulted in either a 

shorter or longer wing link being fitted, 

which introduces local stresses in the wing 

top and bottom surfaces local to rib 2, wing 

links and wing link fitting attachment and 

the fuselage local to Frames 26 and 29. This 

condition, if not corrected, could result in a 

reduction of structural integrity of the 

fuselage/wing attachment with possible 

catastrophic consequences. 

For the reasons described above, the 

present Airworthiness Directive (AD) 

requires the accomplishment of inspections 

and rectification actions, as necessary. 

The unsafe condition could result in loss of 

a wing or controllability of the airplane. The 

inspections include inspecting wing links for 

incorrect part numbers (i.e., parts that are not 

original), inspecting to determine wing 

geometry measurements, and inspecting the 

wing link, bores, bolts, and nuts for 

corrosion. Corrective actions include 

installing wing-to-fuselage fairings and 

repairing. 

Compliance 

(f) You are responsible for having the 

actions required by this AD performed within 

the compliance times specified, unless the 

actions have already been done. 

Actions 

(g) Do the following actions. 

(1) For airplanes subject to maintenance 

review board report (MRBR) requirements: 

Within 30 days after the effective date of this 

AD, revise the supplemental structural 

inspection (SSI) portion of the airplane 

inspection schedule, in accordance with 

paragraph 1.D.(2) of BAE Systems 

(Operations) Limited Inspection Service 

Bulletin ISB.53–175, Revision 1, dated April

applicable time, and repeat at the applicable 

intervals, as specified in Appendix 3 of BAE 

Systems (Operations) Limited Inspection 

Service Bulletin ISB.53–175, Revision 1, 

dated April 2, 2007. Where Appendix 3 of 

BAE Systems (Operations) Limited 

Inspection Service Bulletin ISB.53–175, 

Revision 1, dated April 2, 2007, does not 


erowe on DSK5CLS3C1PROD with RULES
Federal Register / Vol. 75, No. 156 / Friday, August 13, 2010 / Rules and Regulations 49379 

specify a compliance time in either flight 

cycles or in flight hours, use flight cycles. 

(2) For airplanes subject to MRBR 

requirements: Accomplishing the inspections 

and all applicable corrective actions 

specified in paragraph 1.D.(3) of BAE 

Systems (Operations) Limited Inspection 

Service Bulletin ISB.53–175, Revision 1, 

dated April 2, 2007, terminates the revisions 

to the SSI portion of the airplane inspection 

schedule incorporated in accordance with 

paragraph (g)(1) of this AD, provided that if 

any corrosion is found during any inspection 

specified in ‘‘Part C’’ or ‘‘Part D’’ of paragraph 

2.C. of BAE Systems (Operations) Limited 

Inspection Service Bulletin ISB.53–175, 

Revision 1, dated April 2, 2007, repair is 

accomplished before further flight using a 

method approved by the Manager, 

International Branch, ANM 116, Transport 

Airplane Directorate, FAA, or EASA (or its 

delegated agent). 

(3) For operational airplanes subject to 

MRBR-to-supplemental-structuralinspection-document (SSID) transition 

requirements or to SSID requirements: 

Within 5,000 flight cycles after the effective 

date of this AD, do the inspections and all 

applicable corrective actions, in accordance 

with paragraph 2.C. of the Accomplishment 

Instructions of BAE Systems (Operations) 

Limited Inspection Service Bulletin ISB.53– 

175, Revision 1, dated April 2, 2007, except 

if any corrosion is found during any 

inspection specified in ‘‘Part C’’ or ‘‘Part D’’ 

of paragraph 2.C. of BAE Systems 

(Operations) Limited Inspection Service 

Bulletin ISB.53–175, Revision 1, dated April 

2, 2007, repair must be accomplished using 

a method approved by the Manager, 

International Branch, ANM 116, Transport 

Airplane Directorate, FAA, or EASA (or its 

delegated agent). Do all applicable corrective 

actions before further flight, except that 

replacements of all the wing links that are 

not within the specified tolerance must be 

done before the airplane reaches its MRBR 

airframe life limit. 

Note 1: For the purposes of this AD, a 

detailed inspection is: ‘‘An intensive 

examination of a specific item, installation, 

or assembly to detect damage, failure, or 

irregularity. Available lighting is normally 

supplemented with a direct source of good 

lighting at an intensity deemed appropriate. 

Inspection aids such as mirror, magnifying 

lenses, etc., may be necessary. Surface 

cleaning and elaborate procedures may be 

required.’’ 

(4) For any inspection done in accordance 

with paragraph (g)(2) or (g)(3) of this AD: 

Send reports to BAE Systems, Customer 

Liaison, Customer Support (Building 37), 

BAE Systems (Operations) Limited, 

Prestwick International Airport, Ayrshire, 

KA9 2RW, Scotland; fax +44 (0) 1292 675432; 

e-mail raengliason@baesystems.com; at the 

applicable time specified in paragraph 

(g)(4)(i) or (g)(4)(ii) of this AD. The report 

must include the inspection results, a 

description of any discrepancies found, the 

airplane serial number, and the number of 

landings and flight hours on the airplane. 

(i) If the inspection was done on or after 

the effective date of this AD: Submit the 

report within 30 days after the inspection. 

(ii) If the inspection was done before the 

effective date of this AD: Submit the report 

within 30 days after the effective date of this 

AD. 

(5) For airplanes that are non-operational 

as of the effective date of this AD and that 

are subject to MRBR-to-SSID transition 

requirements or to SSID requirements: Before 

returning any airplane to service, do the 

inspections and all applicable corrective 

actions, in accordance with paragraph 2.C. of 

the Accomplishment Instructions of BAE 

Systems (Operations) Limited Inspection 

Service Bulletin ISB.53–175, Revision 1, 

dated April 2, 2007, except if any corrosion 

is found during any inspection specified in 

‘‘Part C’’ or ‘‘Part D’’ of paragraph 2.C. of BAE 

Systems (Operations) Limited Inspection 

Service Bulletin ISB.53–175, Revision 1, 

dated April 2, 2007, repair must be 

accomplished using a method approved by 

the Manager, International Branch, ANM– 

116, Transport Airplane Directorate, FAA, or 

EASA (or its delegated agent). 

(6) Actions accomplished before the 

effective date of this AD in accordance with 

BAE Systems (Operations) Limited 

Inspection Service Bulletin ISB.53–175, 

dated December 21, 2006, are considered 

acceptable for compliance with the 

corresponding action specified in this AD. 

FAA AD Differences 

Note 2: This AD differs from the MCAI 

and/or service information as follows: The 

MCAI does not specify a corrective action if 

corrosion is found during accomplishment of 

the actions specified in ‘‘Part C’’ and ‘‘Part D’’ 

of paragraph 2.C. of BAE Systems 

(Operations) Limited Inspection Service 

Bulletin ISB.53–175, Revision 1, dated April 

2, 2007. This AD requires that if any 

corrosion is found, a repair must be done in 

accordance with a method approved by the 

FAA or EASA (or its delegated agent). 

Other FAA AD Provisions 

(h) The following provisions also apply to 

this AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, International 

Branch, ANM–116, FAA, has the authority to 

approve AMOCs for this AD, if requested

principal avionics inspector (PAI), as 

appropriate, or lacking a principal inspector, 

your local Flight Standards District Office. 

The AMOC approval letter must specifically 

reference this AD. 

(2) Airworthy Product: For any requirement 

in this AD to obtain corrective actions from 

a manufacturer or other source, use these 

actions if they are FAA-approved. Corrective 

actions are considered FAA-approved if they 

are approved by the State of Design Authority 

(or their delegated agent). You are required 

to assure the product is airworthy before it 

is returned to service. 

(3) Reporting Requirements: For any 

reporting requirement in this AD, under the 

provisions of the Paperwork Reduction Act
