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 certain Saab AB, Saab 
Aeronautics Model 340A (SAAB/SF340A) and SAAB 340B airplanes. The NPRM 
published in the Federal Register on June 21, 2017 (82 FR 28271) (``the 
NPRM'').
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2017-0033, dated February 17, 2017 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for all Saab AB, Saab 
Aeronautics Model 340A (SAAB/SF340A) and SAAB 340B airplanes. The MCAI 
states:

    The airworthiness limitations and/or certification maintenance 
instructions for SAAB SF340A and 340B, which are approved by EASA, 
are currently defined and published in the SAAB SF340A and 340B 
Airworthiness Limitation Manual (ALM). These instructions have been 
identified as mandatory for continued airworthiness.
    Failure to accomplish these instructions could result in an 
unsafe condition [reduced structural integrity of the airplane].
    Recently, Saab AB, Aeronautics issued SAAB SF340A and 340B ALM 
Revision 1, mainly to add new inspection tasks for the Main Landing 
Gear drag brace support fitting, and to implement Corrosion 
Prevention and Control Program related tasks.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2017-
0563.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The

[[Page 48918]]

following presents the comment received on the NPRM and the FAA's 
response.

Request To Clarify the Reason for the NPRM

    Silver Airways requested clarification of the need for an AD. 
Silver Airways stated that the proposed requirements are already 
covered by the airworthiness limitation manual.
    We agree that clarification is necessary. Once an aircraft is 
produced under a type certificate, the type design of that particular 
aircraft is fixed in time. Under 14 CFR 21.31(c), the airworthiness 
limitation section (ALS) is part of a product's type design. In order 
to require a revision to an ALS for in-service aircraft, the FAA issues 
an AD under notice and comment rulemaking procedures in accordance with 
the Administrative Procedure Act (APA). Therefore, an AD is necessary 
to mandate the airworthiness limitations in SAAB 340 Airworthiness 
Limitation Manual, Revision 1, dated December 1, 2016, including 
inspection tasks for the drag brace support fitting of the MLG and CPCP 
related tasks. We have not changed this AD in this regard.

Conclusion

    We reviewed the relevant data, considered the comment received, and 
determined that air safety and the public interest require adopting 
this AD as proposed. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    Saab AB, Saab Aeronautics has issued SAAB 340 Airworthiness 
Limitation Manual, Revision 1, dated December 1, 2016. This service 
information describes airworthiness limitations, including inspection 
tasks for the drag brace support fitting of the MLG and CPCP related 
tasks. 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 AD affects 87 airplanes of U.S. registry.
    We estimate the following costs to comply with this 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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes to 
the Director of the System Oversight Division.

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.
