**SUPPLEMENTARY INFORMATION :** 

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Empresa Brasileira de Aeronautica S.A. (Embraer) Model EMB–135BJ airplanes. The NPRM published in the Federal Register on August 26, 2014 (79 FR 50857). The NPRM was prompted by a determination that more restrictive fuel limitations are needed. The NPRM proposed to require revising the maintenance or inspection program to incorporate new compliance times and fuel limitations. We are issuing this AD to detect and correct fatigue cracking of various structural elements and prevent ignition sources in the fuel system.

The Age ˆ ncia Nacional De Aviac

 ̧ a  ̃ o Civil (ANAC), which is the aviation authority for Brazil, has issued Brazilian Airworthiness Directive 2013–12–02, effective December 27, 2013 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all Empresa Brasileira de Aeronautica S.A. (Embraer) Model EMB–135BJ airplanes. The MCAI states:

This [Brazilian] AD was prompted by a new revision to the Airworthiness Limitations Requirements of the Maintenance Planning Guide (MPG–1483). We are issuing this [Brazilian] AD to allow timely detection and correction of fatigue cracking of various structural elements, and to allow the necessary preclusion of ignition sources in the fuel system.

Required actions include revising the maintenance or inspection program, as applicable, to incorporate new compliance times and fuel limitations. You may examine the MCAI in the AD docket on the internet at http:// www.regulations.gov/#!docketDetail; D=FAA-2014-0586.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (79 FR 50857, August 26, 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 50857, dated August 16, 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 50857, dated August 16, 2014).

Related Service Information Under 1 CFR Part 51

Embraer has issued the following service information.

• Temporary Revision (TR) 8–1, dated October 26, 2012, to the Embraer Legacy BJ Maintenance Planning Guide (MPG), MPG–1483.


### 52954 Federal Register / Vol. 80, No. 170 / Wednesday, September 2, 2015 / Rules and Regulations

• TR 8–2, dated December 5, 2012, to the Embraer Legacy BJ MPG, MPG–
1483.

• TR 8–3, dated April 8, 2013, to the Embraer Legacy BJ MPG, MPG–1483.

The service information describes revisions to the maintenance or inspection program to incorporate new compliance times and fuel limitations. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the **ADDRESSES** section of this AD. Costs of Compliance

We estimate that this AD affects 53 airplanes of U.S. registry.

We also estimate that it would take about 1 work-hour 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 on U.S. operators to be $4,505, 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-2014-0586; 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. The street address for the Docket Operations office (telephone 800–647–5527) is in the **ADDRESSES** section. List of Subjects in 14 CFR Part 39

**Airworthiness Directives; Bombardier, Inc. Airplanes** 

**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 chafing of the fuel lines due to contact with the surrounding structures in the fuel tank. This AD requires replacing and modifying fuel lines, revising the maintenance or inspection program, as applicable, to include critical design configuration control limitations (CDCCL) and airworthiness limitation (AWL) items, and, for certain airplanes, removing certain clamps and mounting hardware. We are issuing this AD to prevent chafing of the fuel lines in the fuel tank, which could result in potential ignition sources in the fuel tank in the event of a lightning strike and consequent fire or explosion.

**DATES :**  This AD becomes effective October 7, 2015.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of October 7, 2015.

**ADDRESSES :**  You may examine the AD docket on the Internet at http:// www.regulations.gov/ #!docketDetail;D=FAA-2014-0583 or in person at the Docket Management Facility, U.S. Department of Transportation, Docket Operations, M– 30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue SE., Washington, DC.
