### Airworthiness Directives; Embraer S.A. **Airplanes**

**AGENCY** 

### : Federal Aviation Administration (FAA), Department of Transportation (DOT).

**ACTION** 

### : Final rule.

**SUMMARY** 

### : We are superseding an existing airworthiness directive (AD) for all Embraer S.A. Model ERJ 190–100 STD, –100 LR, –100 IGW, –200 STD, –200 LR, and –200 IGW airplanes. That AD currently requires revising the maintenance program to incorporate modifications in the Airworthiness Limitation Section (ALS) of the EMBRAER ERJ 190 Maintenance Review Board Report (MRBR). This new AD requires revising the maintenance program to incorporate modifications in the ALS of the EMBRAER ERJ 190 MRBR to include new inspection tasks and their respective thresholds and intervals. This AD was prompted by issuance of new inspection tasks and their respective thresholds and intervals. We are issuing this AD since failure to inspect these structural components according to the new ALS tasks, thresholds, and intervals could prevent a timely detection of fatigue cracking, which if not properly addressed, could result in reduced structural integrity of the airplane.

**DATES** 

### : This AD becomes effective January 14, 2013.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of January 14, 2013.

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 June 6, 2012 (77 FR 33334), and proposed to supersede AD 2010– 11–14, Amendment 39–16319 (75 FR 30277, June 1, 2010). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI

states:

During the airplane full scale fatigue test, cracks were found in some structural components of the airplane. Analysis of these cracks resulted in modifications on the Airworthiness Limitation Section (ALS) of Embraer ERJ 190 Maintenance Review Board Report (MRBR), to include new inspections tasks and its respective thresholds and intervals.

Failure to inspect these structural components, according to the new tasks, thresholds and intervals, could prevent a timely detection of fatigue cracking. These cracks, if not properly addressed, could adversely affect the structural integrity of the airplane.

Since this condition may occur in other airplanes of the same type and affects flight safety, a corrective action is required. Thus, sufficient reason exists to request compliance with this [Age ˆ ncia Nacional de Aviac

 ̧ a  ̃ o Civil (ANAC)] AD in the indicated time limit.



### 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 have considered the comments received.
Request To Incorporate New and Revised Structural Airworthiness Limitations

Embraer requested that we include EMBRAER Temporary Revision (TR) 5– 5, dated May 24, 2012; and EMBRAER TR 5–7, dated August 12, 2012; to Appendix A, Part 2, Airworthiness Limitation Inspections (ALI)— Structures, of the EMBRAER 190 MRBR, MRB–1928, in the operators’


## 73271 Federal Register / Vol. 77, No. 237 / Monday, December 10, 2012 / Rules and Regulations

maintenance programs. Embraer points out that those TRs include additional maintenance tasks that were approved in recent design changes, which identify and mitigate potential premature structural cracks.

We disagree. There have been numerous changes to the structural inspection requirements intended to identify potential premature cracks since the last structural airworthiness limitations (EMBRAER TR 2–5, dated December 6, 2007; and EMBRAER TR 2– 6, dated February 12, 2008; to Appendix A, Part 2, Airworthiness Limitation Inspections (ALI) –Structures, of the EMBRAER 190 MRBR, MRB–1928 were mandated in FAA AD 2010–11–14, Amendment 39–16319 (75 FR 30277, June 1, 2010).

The requested changes would alter the actions currently required by this AD, so additional rulemaking would be required. We find that delaying this action would be inappropriate in light of the identified unsafe condition.

In addition, we have contacted the ANAC, the aviation authority for Brazil. ANAC has indicated it intends to mandate the maintenance actions in Appendix A, Parts I, II, and IV of EMBRAER 190 MRBR, MRB–1928, Revision 5, dated November 11, 2010; including EMBRAER TR 5–3, dated November 11, 2010; and EMBRAER TR 5–6, dated November 11, 2010, in addition to the TRs referred to by the commenter. These new maintenance actions include certification maintenance requirements (CMRs) and life-limited parts, in addition to the structural inspections from the TRs referred to by the commenter. As we stated previously, we consider that to delay this AD action would be inappropriate, since we have determined that an unsafe condition exists. When ANAC issues mandatory continued airworthiness instructions that encompass all appropriate airworthiness limitations, including the commenter’s recommended action, we might consider additional rulemaking. We have not changed the AD in this regard.
Explanation of Changes Made to This
AD

We have deleted Note 1 to paragraph (g)(1) of the NPRM (77 FR 33334, June 6, 2012). Instead, we have added the same information in paragraph (g)(2) of this AD.

We also revised the compliance times specified in table 1 to paragraph (g)(1) of this AD to correctly identify the effective date of AD 2010–11–14, Amendment 39–16319 (75 FR 30277, June 1, 2010). Conclusion
We reviewed the available data, including the comment received, and determined that air safety and the public interest require adopting the AD with the changes described previously and minor editorial changes. We have determined that these minor changes:

• Are consistent with the intent that was proposed in the NPRM (77 FR 33334, June 6, 2012) for correcting the unsafe condition; and

• Do not add any additional burden upon the public than was already proposed in the NPRM (77 FR 33334, June 6, 2012).
Costs of Compliance

We estimate that this AD will affect about 88 products of U.S. registry.

The actions that are required by AD 2010–11–14, Amendment 39–16319 (75 FR 30277, June 1, 2010), and retained in this AD take about 1 work-hour per product, at an average labor rate of $85 per work-hour. Based on these figures, the estimated cost of the currently required actions is $85 per product.

We estimate that it will take about 1 work-hour per product to comply with the new basic requirements of this AD.The average labor rate is $85 per workhour. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $7,480, 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 that 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.

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 (77 FR 33334, June 6, 2012), 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**

List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Incorporation by reference, 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 removing airworthiness directive (AD) 2010–11–14, Amendment 39–16319 (75 FR 30277, June 1, 2010), and adding the following new AD:

2012–23–09 Embraer S.A.: Amendment 39– 17265. Docket No. FAA–2012–0590; Directorate Identifier 2011–NM–112–AD.

(a) Effective Date

This airworthiness directive (AD) becomes effective January 14, 2013.


## 73272 Federal Register / Vol. 77, No. 237 / Monday, December 10, 2012 / Rules and Regulations

(b) Affected ADs

This AD supersedes AD 2010–11–14, Amendment 39–16319 (75 FR 30277, June 1, 2010).
(c) Applicability

(1) This AD applies to Embraer S.A. Model ERJ 190–100 STD, –100 LR, and –100 IGW airplanes; and Model ERJ 190–200 STD, –200 LR, and –200 IGW airplanes; certificated in any category; all serial numbers.

(2) This AD requires revisions to certain operator maintenance documents to include new actions (e.g., inspections). Compliance with these actions 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) according to paragraph (j)(1) 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.
(d) Subject

Air Transport Association (ATA) of America Code 52, Doors; 53, Fuselage; 54, Nacelles/Pylons; 55, Stabilizers; 57, Wings; 71, Powerplant; and 78, Engine Exhaust.

(e) Reason

This AD was prompted by reports of cracks in some of the structural components of the airplane. We are issuing this AD since failure to inspect these structural components according to the new airworthiness limitation section (ALS) tasks, thresholds, and intervals could prevent a timely detection of fatigue cracking, which if not properly addressed, could result in reduced structural integrity of the airplane.
(f) Compliance

You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.

(g) Restated Actions: Revision and Compliance Times

This paragraph restates the actions required by paragraph (f) of AD 2010–11–14, Amendment 39–16319 (75 FR 30277, June 1, 2010).

(1) Within 90 days after July 6, 2010 (the effective date of AD 2010–11–14, Amendment 39–16319 (75 FR 30277, June 1, 2010)), revise the ALS of the Instructions for Continued Airworthiness (ICA) to include the tasks specified in table 1 to paragraph (g)(1) of this AD. These tasks are identified in EMBRAER Temporary Revision (TR) 2–5, dated December 6, 2007; and EMBRAER TR 2–6, dated February 12, 2008; to Appendix A, Part 2, Airworthiness Limitation Inspections (ALI) –Structures, of the EMBRAER 190 Maintenance Review Board Report (MRBR),

### : Federal Aviation Administration (FAA), Department of Transportation (DOT).

**ACTION** 

### : Final rule; request for

comments.

**SUMMARY** 

### : We are publishing a new airworthiness directive (AD) for Agusta Model AW139 helicopters, which was sent previously to all known U.S. owners and operators of these helicopters. This AD requires inspecting the pilot’s and co-pilot’s collective and cyclic control sticks for correctly installed attaching hardware. This AD is prompted by a report of an incorrectly installed pilot’s collective stick, pilot’s cyclic stick, and co-pilot’s cyclic stick. These actions are intended to prevent detachment of the cyclic or collective control stick, and subsequent loss of control of the helicopter.

**DATES** 

### : This AD becomes effective December 26, 2012 to all persons except those persons to whom it was made immediately effective by Emergency AD 2012–21–52, issued on October 23, 2012, which contained the requirements of this AD.

We must receive comments on this AD by February 8, 2013.
