Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Embraer Model EMB –135ER, –135KE, –135KL, –135LR, –145, –145ER, –145MR, –145LR, –145XR, –145MP, and –145EP airplanes. The NPRM published in the Federal Register on September 4, 2014 (79 FR 52588).

The Age ˆ ncia Nacional de Aviac

 ̧ a  ̃ o Civil (ANAC), which is the aviation authority for Brazil, has issued Brazilian Airworthiness Directive 2014–01–01, dated January 20, 2014 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all Embraer Model EMB –135ER, –135KE, –135KL, –135LR, –145, –145ER, –145MR, –145LR, –145XR, –145MP, and –145EP airplanes. The MCAI states:

This [Brazilian] AD was prompted by a new revision to the airworthiness limitations requirements [related to the pylon yokes I and II, and the skin panel of the windshield pillar] of the Maintenance Review Board Report. We are issuing this [Brazilian] AD to ensure that fatigue cracking of various structural elements is detected and corrected.

You may examine the MCAI in the AD docket on the Internet at http:// www.regulations.gov/ #!documentDetail;D=FAA-2014-0622-
0002.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (79 FR 52588, September 4, 2014) 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 this 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 (79 FR 52588, September 4, 2014) for correcting the unsafe condition; and

• Do not add any additional burden upon the public than was already proposed in the NPRM (79 FR 52588, September 4, 2014).

Related Service Information

We reviewed EMBRAER EMB145 Temporary Revision 15–3, dated August 26, 2013, to the Airworthiness Limitation Requirements of the EMBRAER EMB145 Maintenance Review Board Report MRB 145/1150; and EMBRAER EMB145 Temporary Revision 15–4, dated August 26, 2013, to the Airworthiness Limitation Requirements of the EMBRAER EMB145 Maintenance Review Board Report MRB–145/1150. The service information describes airworthiness limitations related to inspections of certain fuselage or pylon components. You can find this information at http:// www.regulations.gov by searching for and locating Docket No. FAA–2014–
0622. Costs of Compliance

We estimate that this AD affects 688 airplanes of U.S. registry.

We also estimate that it will take about 1 work-hour per product to comply with the basic requirements of this AD. The average labor rate is $85


### 5024 Federal Register / Vol. 80, No. 20 / Friday, January 30, 2015 / Rules and Regulations

per work-hour. Based on these figures, we estimate the cost of this AD on U.S. operators to be $58,480, 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. Examining the AD Docket

You may examine the AD docket on the Internet at http:// www.regulations.gov/ #!docketDetail;D=FAA-2014-0622; 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 this AD, the regulatory evaluation, any comments received, and other information.

For the purposes of this AD, the initial compliance times (identified as ‘‘Threshold’’ or ‘‘T’’ in the service information) are expressed in ‘‘total flight cycles.’’
(h) No Alternative Actions and Intervals

After accomplishment of the revision required by paragraph (g) of this AD, no alternative actions ( e.g., inspections) or intervals may be used unless the actions or intervals are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (i)(1) of this AD.

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

**ACTION :**  Final rule.

**SUMMARY :**  We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC–8–400 series airplanes. This AD was prompted by reports of two in-service incidents where one side of the main landing gear (MLG) did not achieve down-lock. This AD requires doing a detailed inspection of the apex joints of the stabilizer brace lock link in the MLG for clearance; rectifying and repairing the clearance gap, if necessary; and lubricating the apex joints of the stabilizer brace lock link in the MLG. We are issuing this AD to detect and correct insufficiently greased stabilizer brace lock linkage of the MLG and over-torqued lock linkage attachment bolts, which could lead to the failure to extend and down-lock the MLG, and could affect the safe landing of the airplane.

**DATES :**  This AD becomes effective March 6, 2015.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of March 6, 2015.

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Bombardier, Inc. Model DHC–8–400 series airplanes. The NPRM published in the Federal Register on April 8, 2014 (79 FR 19299).

Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2013–19, dated July 18, 2013 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition certain Bombardier, Inc. Model DHC–8– 400 series airplanes. The MCAI states:

There have been two reported in-service incidents where one side of the main landing gear (MLG) did not achieve down-lock resulting in a gear unsafe indication. In both cases, the MLG was ultimately extended and down-lock was achieved through the use of the alternate extension system or by cycling the MLG. The investigation revealed that in both cases, the MLG stabilizer brace lock linkages were insufficiently greased and thelock linkage attachment bolts were overtorqued.

Failure to extend and down-lock the MLG could adversely affect the safe landing of the aeroplane.

This [TCCA] AD mandates the [detailed] inspection, rectification [and repair the clearance gap] as required, and lubrication of both MLG stabilizer brace lock link apex joints.

You may examine the MCAI in the AD docket on the Internet at http:// www.regulations.gov/ #!documentDetail;D=FAA-2014-0188-
0002.

Comments

We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM (79 FR 19299, April 8, 2014) and the FAA’s response to each comment. Request To Include Only Requirements That Affect the Unsafe Condition

Horizon Air requested that the NPRM (79 FR 19299, April 8, 2014) require only the section of the Accomplishment Instructions that corrects the unsafe condition. Horizon Air stated that the job set-up and close-out sections
