E:\FR\FM\22MYP1.SGM 22MYP1 23159 Federal Register / Vol. 82, No. 97 / Monday, May 22, 2017 / Proposed Rules Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2016–0234, dated November 24, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Saab AB, Saab Aeronautics Model 340A (SAAB/ SF340A) airplanes. The MCAI states: Circuit breakers of an unsuitable strength have been found installed on SAAB SF340A aeroplanes, failing in protecting the system from an overcurrent. This condition, if not corrected, could lead to the overheating of wires, possibly resulting in smoke or fire on the aeroplane. To address this potential unsafe condition, Saab issued [service bulletin] SB 340–33–058 (later revised) to provide instructions for replacement of circuit breakers. For the reason described above, this [EASA] AD requires replacement of circuit breakers of unsuitable strength in the passenger reading light system. FAA’s Determination and Requirements of This Proposed AD You may examine the MCAI in the AD docket on the Internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2017– 0479. This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design. Related Service Information Under 1 CFR Part 51 We reviewed Saab Service Bulletin 340–33–058, Revision 01, dated October 21, 2016. The service information describes procedures for replacing any circuit breaker having part number (P/ N) MS3320–10 installed at position 2LJ (L25) and position 4LJ (L26) with a circuit breaker having P/N MS3320–7– 5. 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. Costs of Compliance We estimate that this proposed AD affects 19 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost Replacement ................................................... 2 work-hours × $85 per hour = $170 ............. 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. nlaroche on DSK30NT082PROD with PROPOSALS Regulatory Findings We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 VerDate Sep<11>2014 12:41 May 19, 2017 Jkt 241001 Parts cost responsibilities among the various levels of government. For the reasons discussed above, I certify this proposed regulation: 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.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2016-0234, dated November 24, 2016 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for certain Saab AB, Saab 
Aeronautics Model 340A (SAAB/SF340A) airplanes. The MCAI states:

    Circuit breakers of an unsuitable strength have been found 
installed on SAAB SF340A aeroplanes, failing in protecting the 
system from an overcurrent.
    This condition, if not corrected, could lead to the overheating 
of wires, possibly resulting in smoke or fire on the aeroplane.
    To address this potential unsafe condition, Saab issued [service 
bulletin] SB 340-33-058 (later revised) to provide instructions for 
replacement of circuit breakers.
    For the reason described above, this [EASA] AD requires 
replacement of circuit breakers of unsuitable strength in the 
passenger reading light system.

    You may examine the MCAI in the AD docket on the Internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2017-
0479.

Related Service Information Under 1 CFR Part 51

    We reviewed Saab Service Bulletin 340-33-058, Revision 01, dated 
October 21, 2016. The service information describes procedures for 
replacing any circuit breaker having part number (P/N) MS3320-10 
installed at position 2LJ (L25) and position 4LJ (L26) with a circuit 
breaker having P/N MS3320-7-5. 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.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Costs of Compliance

    We estimate that this proposed AD affects 19 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 proposed 
regulation:
    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.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

Saab AB, Saab Aeronautics (Formerly Known as Saab AB, Saab 
Aerosystems): Docket No. FAA-2017-0479; Directorate Identifier 2016-
NM-202-AD.

(a) Comments Due Date

    We must receive comments by July 6, 2017.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Saab AB, Saab Aeronautics Model 340A (SAAB/
SF340A) airplanes, certificated in any category, serial numbers 004 
through 138 inclusive; except those on which Saab Service Bulletin 
340-33-053 (modification/removal for cargo/freighter configuration) 
has been embodied.

(d) Subject

    Air Transport Association (ATA) of America Code 33, Lights.

(e) Reason

    This AD was prompted by the discovery of circuit breakers of 
unsuitable strength that fail to protect the system from 
overcurrent. We are issuing this AD to prevent such conditions, 
which could lead to overheating of the wires and possibly result in 
smoke or fire in the airplane.
