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: 

During aircraft full scale fatigue test, it has 

been found the occurrence of cracks in the 

cockpit windshield post lower eyelet fitting 

at the attachment of the center post on the 

forward fuselage (SSI 53–10–19). Further 

analysis of this cracking resulted in 

modifications on the aircraft Airworthiness 

Limitation Items (ALI), to include new 

inspection tasks and its respective intervals. 

Undetected fatigue cracking in this area 

could adversely affect the structural integrity 

of these airplanes. 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective July 

6, 2010. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of July 6, 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 February 18, 2009 (74 FR 

7570). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

During aircraft full scale fatigue test, it has 

been found the occurrence of cracks in the 

cockpit windshield post lower eyelet fitting 

at the attachment of the center post on the 

forward fuselage (SSI 53–10–19). Further 

analysis of this cracking resulted in 

modifications on the aircraft Airworthiness 

Limitation Items (ALI), to include new 

inspection tasks and its respective intervals. 

Undetected fatigue cracking in this area 

could adversely affect the structural integrity 

of these airplanes. 

The corrective action is revising the 

Airworthiness Limitations Section 

(ALS) of the Instructions for Continued 

Airworthiness to incorporate new 

structural inspection requirements. You 

may obtain further information by 

examining the MCAI in the AD docket. 

Explanation of Revised Service 

Information 

Empresa Brasileira de Aeronautica 

S.A. (EMBRAER) has issued Revision 

12, dated September 19, 2008, of 

Appendix 2, ‘‘Airworthiness Limitation 

Requirements,’’ of EMBRAER EMB135/ 

EMB145 Maintenance Review Board 

Report (MRBR) MRB–145/1150. In the 

NPRM we referred to EMBRAER 

EMB135/EMB145 MRBR MRB–145/ 

1150, Revision 11, dated September 19, 

2007, as an appropriate source of service 

information. 

We have revised paragraph Table 1 of 

this AD to refer to Appendix 2, 

‘‘Airworthiness Limitation 

Requirements,’’ of EMBRAER EMB135/ 

EMB145 MRBR MRB–145/1150, 

Revision 12, dated September 19, 2008. 

We have also added a new paragraph 

(f)(3) to this AD to specify that actions 

done before the effective date of this AD 

in accordance with EMBRAER EMB135/ 

EMB145 MRBR MRB–145/1150, 

Revision 11, dated September 19, 2007, 

are acceptable for compliance with the 

corresponding requirements of this AD. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

considered the comments received. 

Request To Extend Grace Period 

EMBRAER requests that we consider 

extending the grace period for doing the 

tasks required by paragraph (f) of the 

NPRM from 200 flight cycles after 

revising the ALS to 500 flight cycles 

after revising the ALS. EMBRAER 

explains that the extension of the grace 

period would allow operators to better 

program their maintenance schedules, 

thereby avoiding grounding airplanes 

without affecting flight safety. 

We disagree with the request to 

extend the grace period to 500 flight 

cycles after revising the ALS. The 

commenter did not provide any 

technical information to substantiate the 

assertion that the extension would not 

adversely affect flight safety. However, 

under the provisions of paragraph (g)(1) 

of this AD, we will consider requests for 

adjustments to the grace period if data 

are submitted to substantiate that such 

an adjustment would provide an 

acceptable level of safety. We have not 

changed the AD in this regard. 

Request To Allow Later Revisions of 

Service Information 

EMBRAER recommends that we 

accept later revisions of Appendix 2, 

‘‘Airworthiness Limitation 

Requirements,’’ of EMBRAER EMB135/ 

EMB145 Maintenance Review Board 

Report (MRBR) MRB–145/1150, 

Revision 11, dated September 19, 2007. 

EMBRAER points out that AD 2008–13– 

14, Amendment 39–15577 (73 FR 

35904, June 25, 2008), accepts later 

revisions of the MRBR included in that 

AD. 

We disagree with adding a general 

statement to the AD that accepts any 

later revision of EMBRAER MRBR 

MRB–145/1150, Revision 11, dated 

September 19, 2007, that we have not 

reviewed and approved. We note that 

we approved use of later revisions of the 

MRBR referenced in AD 2008–13–14 

only if approved by the Manager, ANM– 

116, FAA, or Ageˆncia Nacional de 

Aviac ̧a ̃o Civil (or its delegated agent). 

We cannot use the phrase, ‘‘or later 

FAA-approved revisions,’’ in an AD 

when referring to the service document 

because doing so violates Office of the 

Federal Register (OFR) regulations for 

approval of materials ‘‘incorporated by 

reference’’ in rules. To allow operators 

to use later revisions of the referenced 

document (issued after publication of 

the AD), either we must revise the AD 

to reference specific later revisions, or 


srobinson on DSKHWCL6B1PROD with RULES
30288 Federal Register / Vol. 75, No. 104 / Tuesday, June 1, 2010 / Rules and Regulations 

operators must request approval to use 

later revisions as an alternative method 

of compliance with this AD under the 

provisions of paragraph (g)(1) of this 

AD. 

However, as stated previously, we 

have reviewed and approved Appendix 

2, ‘‘Airworthiness Limitation 

Requirements,’’ of EMBRAER EMB135/ 

EMB145 MRBR MRB–145/1150, 

Revision 12, dated September 19, 2008, 

which is now referenced as the 

appropriate source of service 

information for this AD. We have made 

no further change to this AD in this 

regard. 

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting the AD 

with the changes described previously. 

We also 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. 

Explanation of Change to Costs of 

Compliance 

Since issuance of the NPRM, we have 

increased the labor rate used in the 

Costs of Compliance from $80 per workhour to $85 per work-hour. The Costs of 

Compliance information, below, reflects 

this increase in the specified hourly 

labor rate. 

Costs of Compliance 

We estimate that this AD will affect 

709 products of U.S. registry. We also 

estimate that it will take about 1 workhour 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 to the U.S. operators to 

be $60,265, 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, 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: 

2010–11–01 Empresa Brasileira de 

Aeronautica S.A. (EMBRAER): 

Amendment 39–16306. Docket No. 

FAA–2009–0132; Directorate Identifier 

2008–NM–081–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective July 6, 2010. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to all Empresa 

Brasileira de Aeronautica S.A. (EMBRAER) 

Model EMB–135BJ, –135ER, –135KE, 

–135KL, –135LR, –145, –145ER, –145MR, 

–145LR, –145XR, –145MP, and –145EP 

airplanes, certificated in any category, all 

serial numbers, except Model EMB–145LR 

airplanes that have been modified in 

accordance with Brazilian Supplemental 

Type Certificates 2002S06–09, 2002S06–10, 

and 2003S08–01. 

Note 1: This AD requires revisions to 

certain operator maintenance documents to 

include new inspections. Compliance with 

these inspections is required by 14 CFR 

91.403(c). For airplanes that have been 

previously modified, altered, or repaired in 

the areas addressed by these inspections, the 

operator may not be able to accomplish the 

inspections described in the revisions. In this 

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

the operator must request approval for an 

alternative method of compliance according 

to paragraph (g) of this AD. The request 

should include a description of changes to 

the required inspections that will ensure the 

continued operational safety of the airplane. 

The FAA has provided guidance for this 

determination in Advisory Circular (AC) 25– 

1529–1. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 53: Fuselage. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 


srobinson on DSKHWCL6B1PROD with RULES
Federal Register / Vol. 75, No. 104 / Tuesday, June 1, 2010 / Rules and Regulations 30289 

During aircraft full scale fatigue test, it has 

been found the occurrence of cracks in the 

cockpit windshield post lower eyelet fitting 

at the attachment of the center post on the 

forward fuselage (SSI 53–10–19). Further 

analysis of this cracking resulted in 

modifications on the aircraft Airworthiness 

Limitation Items (ALI), to include new 

inspection tasks and its respective intervals. 

Undetected fatigue cracking in this area 

could adversely affect the structural integrity 

of these airplanes. 

The corrective action is revising the 

Airworthiness Limitations Section (ALS) of 

the Instructions for Continued Airworthiness 

to incorporate new structural inspection 

requirements. 

Actions and Compliance 

(f) Unless already done, do the following 

actions. 

(1) Within 90 days after the effective date 

of this AD revise the ALS of the Instructions 

for Continued Airworthiness to incorporate 

the structural inspection item (SSI) 53–10– 

19’s applicable tasks identified in Appendix 

2, ‘‘Airworthiness Limitation Requirements,’’ 

of the applicable document listed in Table 1 

of this AD. The initial compliance times for 

the task start from the applicable time 

specified in SSI 53–10–19 or within 200 

flight cycles after revising the ALS, 

whichever occurs later. Repeat the applicable 

inspection thereafter at the interval specified 

in Appendix 2 of the applicable document 

listed in Table 1 of this AD, except as 

provided by paragraphs (f)(2) and (g) of this 

AD.

in the MCAI as an applicable document to 

incorporate into the maintenance program. 

(2) After accomplishing the actions 

specified in paragraph (f)(1) of this AD, no 

alternative inspections or inspection 

intervals may be used unless the inspection 

or inspection interval is approved by the 

Manager, International Branch, ANM–116, 

Transport Airplane Directorate, FAA, or the 

Ageˆncia Nacional de Aviac ̧a ̃o Civil (ANAC) 

(or its delegated agent); or unless the 

inspection or interval is approved as an 

alternative method of compliance (AMOC) in 

accordance with the procedures specified in 

paragraph (g)(1) of this AD. 

(3) Actions done before the effective date 

of this AD in accordance with EMBRAER 

EMB135/EMB145 MRBR MRB–145/1150, 

Revision 11, dated September 19, 2007, are 

acceptable for compliance with the 

corresponding requirements of this AD. 

FAA AD Differences 

Note 3: This AD differs from the MCAI 

and/or service information as follows: 

(1) We have removed the requirement to 

mandate the SSI tasks in Section 4— 

‘‘Structural Inspection Requirements,’’ 

of the applicable document listed in 

Table 1 of this AD which are 

referred to in the MCAI. Those SSI tasks are 

included in Appendix 2, ‘‘Airworthiness 

Limitation Requirements,’’ of the applicable 

document listed in Table 1 of this AD. 

(2) We have not included the 21,336-flightcycle threshold specified in the MCAI 

because the airplanes in the U.S.-registered 

fleet have surpassed that threshold. Instead, 

we included a 200-flight-cycle grace period 

for accomplishing the SSI 53–10–19 tasks. 

Other FAA AD Provisions 

(g) The following provisions also apply to 

this AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, International 

Branch, ANM–116, Transport Airplane 

Directorate, FAA, has the authority to 

approve AMOCs for this AD, if requested 

using the procedures found in 14 CFR 39.19. 

Send information to ATTN: Todd Thompson, 

Aerospace Engineer, 1601 Lind Avenue, SW., 

Renton, Washington 98057–3356; telephone 

(425) 227–1175; fax (425) 227–1149. Before 

using any approved AMOC on any airplane 

to which the AMOC applies, notify your 

principal maintenance inspector (PMI) or 

principal avionics inspector (PAI), as 

appropriate, or lacking a principal inspector, 

your local Flight Standards District Office. 

(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 

(44 U.S.C. 3501 et seq.), the Office of 

Management and Budget (OMB) has 

approved the information collection 

requirements and has assigned OMB Control 

Number 2120–0056.

ACTION: Final rule; request for 

comments. 

SUMMARY: The FAA is superseding an 

existing emergency airworthiness 

directive (AD) 2009–24–52 that was sent 

previously to all known U.S. owners 

and operators of TCM 240, 360, 470, 

520, and 550 series reciprocating 

engines. That AD requires before further 

flight, replacing certain part number 

(P/N) hydraulic lifters. This AD results 

from TCM reporting another occurrence 

of rapid wear on the face of hydraulic 

lifters, P/Ns 657913, 657915, and 

657916, and from the need to expand 

the applicability of this AD to include 

the TCM 346 series reciprocating 

engines and the R–RM IO–240–A 

reciprocating engines. We are issuing 

this AD to prevent excessive hydraulic 

lifter wear, which can result in loss of 

engine power and loss of control of the 

airplane.
