AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are superseding an 

existing airworthiness directive (AD) 

that applies to 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: 

* * * BAE Systems (Operations) Ltd has 

issued Revision 33 of the AMM [airplane 

maintenance manual] to amend Chapter 05– 

10–10 by adding one new Structurally 

Significant Item (SSI) and increasing the 

repeat inspection period on another SSI. 

Failure to comply with this revision 

constitutes an unsafe condition. 

* * * * * 

The unsafe condition is failure of 

certain structurally significant items, 

including the main landing gear and the 

nose landing gear, which could result in 

reduced structural integrity of the 

airplane; and fuel vapor ignition 

sources, which could result in a fuel 

tank explosion and consequent loss of 

the airplane. We are issuing this AD to 

require actions to correct the unsafe 

condition on these products. 

DATES: This AD becomes effective 

November 23, 2011. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of November 23, 2011. 

The Director of the Federal Register 

previously approved the incorporation 

by reference of certain other 

publications listed in this AD as of June 

11, 2009 (74 FR 21246, May 7, 2009).

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 April 8, 2011 (76 FR 19716), 

and proposed to supersede AD 2009– 

10–02, Amendment 39–15897 (74 FR 

21246, May 7, 2009). That NPRM 

proposed to correct an unsafe condition 

for the specified products. The MCAI 

states: 

The Jetstream J41 Aircraft Maintenance 

Manual (AMM), includes the following 

chapters: 

—05–10–10 ‘‘Airworthiness Limitations’’, 

—05–10–20 ‘‘Certification Maintenance 

Requirements’’, and, 

—05–10–30 ‘‘Critical Design Configuration 

Control Limitations (CDCCL)—Fuel 

System.’’ 

Compliance with these chapters has been 

identified as mandatory actions for continued 

airworthiness and EASA AD 2009–0052 was 

issued to require operators to comply with 

those instructions. 

Since the issuance of that AD, BAE 

Systems (Operations) Ltd has issued Revision 

33 of the AMM to amend Chapter 05–10–10 

by adding one new Structurally Significant 

Item (SSI) and increasing the repeat 

inspection period on another SSI. Failure to 

comply with this revision constitutes an 

unsafe condition. 

For the reasons described above, this 

[EASA] AD, which supersedes EASA AD 

2009–0052, requires the implementation of 

the new or more restrictive maintenance 

requirements and/or airworthiness 

limitations as specified in the defined parts 

of Chapter 05 of the AMM at Revision 33. 

The unsafe condition is failure of 

certain structurally significant items, 

including the main landing gear and the 

nose landing gear, which could result in 

reduced structural integrity of the 

airplane; and fuel vapor ignition 

sources, which could result in a fuel 

tank explosion and consequent loss of 

the airplane. 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 (76 

FR 19716, April 8, 2011) or on the 

determination of the cost to the public. 

Revised Aircraft Maintenance Manual 

(AMM) 

Since issuance of the NPRM (76 FR 

19716, April 8, 2011), we have reviewed 

Subjects 05–10–10, ‘‘Airworthiness 

Limitations’’; 05–10–20, ‘‘Certification 

Maintenance Requirements’’; and 05– 

10–30, ‘‘Critical Design Configuration 

Control Limitations (CDCCL)—Fuel 

System’’; of Chapter 05, ‘‘Airworthiness 

Limitations’’, of the BAE Systems 

(Operations) Limited Jetstream Series 

4100 AMM, Revision 35, dated February 

15, 2011. We have revised paragraph (i) 

of this AD to reference this revision. 

We have also added paragraph (j) to 

this AD to give credit for Subjects 05– 

10–10, ‘‘Airworthiness Limitations’’; 

05–10–20, ‘‘Certification Maintenance 

Requirements’’; and 05–10–30, ‘‘Critical 

Design Configuration Control 

Limitations (CDCCL)—Fuel System’’; of 

Chapter 05 ‘‘Airworthiness 

Limitations,’’ of the BAE Systems 

(Operations) Limited Jetstream Series 

4100 AMM, Revision 33, dated February 

15, 2010. 

Conclusion 

We reviewed the available data, and 

determined that air safety and the 

public interest require adopting the AD 

with the changes described previously. 

We determined that these changes 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 

about 3 products of U.S. registry. 

The actions that are required by AD 

2009–10–02 (74 FR 21246, May 7, 2009) 

and retained in this AD take about 1 

work-hour per product, at an average 

labor rate of $85 per work-hour. 

Required parts cost about $85 per 

product. Based on these figures, the 

estimated cost of the currently required 

actions is $85 per product. 

We estimate that it will take about 1 

additional work-hour per product to 

comply with the new 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 to the U.S. operators to be $255, 

or $85 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 (76 FR 19716, April 

8, 2011), 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 

removing Amendment 39–15897 (74 FR 

21246, May 7, 2009) and adding the 

following new AD: 

2011–21–06 BAE SYSTEMS (Operations) 

Limited: Amendment 39–16829. Docket 

No. FAA–2011–0306; Directorate 

Identifier 2010–NM–176–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective November 23, 2011. 

Affected ADs 

(b) This AD supersedes AD 2009–10–02, 

Amendment 39–15897 (74 FR 21246, May 7, 

2009). 

Applicability 

(c) This AD applies to all BAE SYSTEMS 

(Operations) Limited Model 4101 airplanes, 

certificated in any category. 

Note 1: This AD requires revisions to 

certain operator maintenance documents to 

include new actions (e.g., inspections) and/ 

or Critical Design Configuration Control 

Limitations (CDCCLs). Compliance with 

these actions and/or CDCCLs is required by 

14 CFR 91.403(c). For airplanes that have 

been previously modified, altered, or 

repaired in the areas addressed by this AD, 

the operator may not be able to accomplish 

the actions described in the revisions. In this 

situation, to comply with 14 CFR 91.403(c), 

the operator must request approval of an 

alternative method of compliance (AMOC) 


sroberts on DSK5SPTVN1PROD with RULES
64790 Federal Register / Vol. 76, No. 202 / Wednesday, October 19, 2011 / Rules and Regulations 

according to paragraph (l) of this AD. The 

request should include a description of 

changes to the required actions that will 

ensure the continued operational safety of 

the airplane. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 05. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

* * * BAE Systems (Operations) Ltd has 

issued Revision 33 of the AMM [airplane 

maintenance manual] to amend Chapter 05– 

10–10 by adding one new Structurally 

Significant Item (SSI) and increasing the 

repeat inspection period on another SSI. 

Failure to comply with this revision 

constitutes an unsafe condition. 

* * * * * 

The unsafe condition is failure of certain 

structurally significant items, including the 

main landing gear and the nose landing gear, 

which could result in reduced structural 

integrity of the airplane; and fuel vapor 

ignition sources, which could result in a fuel 

tank explosion and consequent loss of the 

airplane. 

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. 

Restatement of Requirements of AD 2009– 

10–02, Amendment 39–15897 (74 FR 21246, 

May 7, 2009) 

Revise Airworthiness Limitations Section 

(AWL) of Instructions for Continued 

Airworthiness 

(g) Within 90 days after June 11, 2009 (the 

effective date of AD 2009–10–02, 

Amendment 39–15897 (74 FR 21246, May 7, 

2009)): Revise the AWL section of the 

Instructions for Continued Airworthiness by 

incorporating the instructions of Subjects 05– 

10–10, ‘‘Airworthiness Limitations,’’ 05–10– 

20, ‘‘Certification Maintenance 

Requirements,’’ and 05–10–30, ‘‘Critical 

Design Configuration Control Limitations 

(CDCCL)—Fuel System,’’ of Chapter 05, 

‘‘Airworthiness Limitations,’’ of the BAE 

Systems (Operations) Limited Jetstream 

Series 4100 Airplane Maintenance Manual 

(AMM), Revision 31, dated February 15, 

2009. Thereafter, except as provided in 

paragraph (l) of this AD, no alternative 

replacement times or inspection intervals 

may be approved for any affected component. 

Doing the actions required by paragraph (i) 

of this AD terminates the requirements of this 

paragraph. 

(h) Where paragraph 2.A.(2) of Subject 05– 

10–10, ‘‘Airworthiness Limitations,’’ of 

Chapter 05, ‘‘Airworthiness Limitations,’’ of 

the BAE Systems (Operations) Limited 

Jetstream Series 4100 AMM, Revision 31, 

dated February 15, 2009, specifies that 

certain landing gear units ‘‘must be removed 

before 31st March 2008,’’ this AD requires 

compliance within 60 days after June 11, 

2009. 

New Requirements of This AD With Revised 

Service Information 

Maintenance Program Revision 

(i) Within 90 days after the effective date 

of this AD: Revise the maintenance program 

by incorporating Subjects 05–10–10, 

‘‘Airworthiness Limitations’’; 05–10–20,

and 05–10–30, ‘‘Critical Design Configuration 

Control Limitations (CDCCL)—Fuel System’’; 

of Chapter 05, ‘‘Airworthiness Limitations,’’ 

of the BAE Systems (Operations) Limited 

Jetstream Series 4100 AMM, Revision 35, 

dated February 15, 2011. Doing the actions 

required by this paragraph terminates the 

requirements of paragraph (g) of this AD. The 

initial compliance times for the tasks are at 

the applicable times specified in paragraphs 

(i)(1), (i)(2), and (i)(3) of this AD. 

(1) For replacement tasks of life limited 

parts specified in Subject 05–10–10, 

‘‘Airworthiness Limitations,’’ of Chapter 05, 

‘‘Airworthiness Limitations,’’ of the BAE 

Systems (Operations) Limited Jetstream 

Series 4100 AMM, Revision 35, dated 

February 15, 2011: Prior to the applicable 

flight cycles (landings) or flight hours (flying 

hours) on the part specified in the 

‘‘Mandatory Life Limits’’ column in Subject 

05–10–10, or within 90 days after the 

effective date of this AD, whichever occurs 

later. 

(2) For structurally significant item tasks 

specified in Subject 05–10–10, 

‘‘Airworthiness Limitations,’’ of Chapter 05, 

‘‘Airworthiness Limitations,’’ of the BAE 

Systems (Operations) Limited Jetstream 

Series 4100 AMM, Revision 35, dated 

February 15, 2011: Prior to the accumulation 

of the applicable flight cycles specified in the 

‘‘Initial Inspection’’ column in Subject 05– 

10–10, or within 90 days after the effective 

date of this AD, whichever occurs later. 

(3) For certification maintenance

‘‘Airworthiness Limitations,’’ of the BAE 

Systems (Operations) Limited Jetstream 

Series 4100 AMM, Revision 35, dated 

February 15, 2011: Prior to the accumulation 

of the applicable flight hours specified in the 

‘‘Time Between Checks’’ column in Subject 

05–10–20, or within 90 days after the 

effective date of this AD, whichever occurs 

later; except for tasks that specify ‘‘first flight 

of the day’’ in the ‘‘Time Between Checks’’ 

column in Subject 05–10–20, the initial 

compliance time is the first flight of the next 

day after doing the revision required by 

paragraph (i) of this AD, or within 90 days 

after the effective date of this AD, whichever 

occurs later. 

Credit for Actions Accomplished in 

Accordance With Previous Service 

Information 

(j) Actions done before the effective date of 

this AD in accordance with Subjects 05–10– 

10, ‘‘Airworthiness Limitations’’; 05–10–20, 

‘‘Certification Maintenance Requirements’’; 

and 05–10–30, ‘‘Critical Design Configuration 

Control Limitations (CDCCL)—Fuel System’’; 

of Chapter 05, ‘‘Airworthiness Limitations,’’ 

of the BAE Systems (Operations) Limited 

Jetstream Series 4100 AMM, Revision 33, 

dated February 15, 2010; are acceptable for 

compliance with the requirements of 

paragraph (i) of this AD. 

No Alternative Actions, Intervals, and/or 

CDCCLs 

(k) After accomplishing the revision 

required by paragraph (i) of this AD, no 

alternative actions (e.g., inspections), 

intervals, and/or CDCCLs may be used unless 

the actions, intervals, and/or CDCCLs are 

approved as an alternative method of 

compliance (AMOC) in accordance with the 

procedures specified in paragraph (l) of this 

AD. 

FAA AD Differences 

Note 2: This AD differs from the MCAI 

and/or service information as follows: 

Although EASA Airworthiness Directive 

2010–0098, dated May 27, 2010, specifies 

both revising the maintenance program to 

include limitations, and doing certain 

repetitive actions (e.g., inspections) and/or 

maintaining CDCCLs, this AD only requires 

the revision. Requiring a revision of the 

maintenance program, rather than requiring 

individual repetitive actions and/or 

maintaining CDCCLs, requires operators to 

record AD compliance only at the time the 

revision is made. Repetitive actions and/or 

maintaining CDCCLs specified in the 

airworthiness limitations must be complied 

with in accordance with 14 CFR 91.403(c). 

Other FAA AD Provisions 

(l) 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 

using the procedures found in 14 CFR 39.19. 

In accordance with 14 CFR 39.19, send your 

request to your principal inspector or local 

Flight Standards District Office, as 

appropriate. If sending information directly 

to the International Branch, send it to ATTN: 

Todd Thompson, Aerospace Engineer, 

International Branch, ANM–116, Transport 

Airplane Directorate, FAA, 1601 Lind 

Avenue, SW., Renton, Washington 98057– 

3356; telephone (425) 227–1175; fax (425) 

227–1149. Before using any approved AMOC, 

notify your appropriate principal inspector, 

or lacking a principal inspector, the manager 

of the local flight standards district office/ 

certificate holding 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.

AGENCY: Federal Aviation 

Administration (FAA), 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) 

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: 

Analysis of service data carried out by 

Rolls-Royce Deutschland has shown that the 

effect of touch-and-go and overshoot on life 

cycle counting is higher than anticipated. 

Therefore, the life cycle counting method for 

touch-and-go and overshoot as defined by the 

Time Limits Manual needs to be changed to 

reflect this higher effect on life. 

We are issuing this AD to prevent 

failure of high-energy, life-limited parts, 

uncontained engine failure, and damage 

to the airplane. 

DATES: This AD becomes effective 

November 23, 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 July 5, 2011 (76 FR 39033). 

That NPRM proposed to correct an 

unsafe condition for the specified 

products. The MCAI states that: 

Analysis of service data carried out by 

Rolls-Royce Deutschland has shown that the 

effect of touch-and-go and overshoot on life 

cycle counting is higher than anticipated. 

Therefore, the life cycle counting method for 

touch-and-go and overshoot as defined by the 

Time Limits Manual needs to be changed to 

reflect this higher effect on life. 

This AD requires a change of the life cycle 

counting method for touch-and-go and 

overshoot for all critical parts and the Low 

Pressure (LP) compressor blades as specified 

in the Rolls-Royce Deutschland Alert NMSB– 

BR700–72–A900504 Revision 1. The chapter 

05–00–01 and 05–00–02 of the applicable 

Time Limits Manuals will be revised 

accordingly. 

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. 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed. 

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 

described in a separate paragraph of the 

AD, and take precedence over the 

actions copied from the MCAI. 

Costs of Compliance 

Based on the service information, we 

estimate that this AD would affect about 

1,052 products of U.S. registry. We also 

estimate that it would take about 1 

work-hour per product to comply with 

this AD. The average labor rate is $85
