SUPPLEMENTARY INFORMATION: 

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. 
The NPRM published in the Federal Register on August 12, 2013 (78 FR 
48828). The NPRM proposed to require initial and repetitive 
inspections, replacement of cracked cylinders, and replacement of 
cylinder assemblies at reduced times-in-service. The NPRM also proposed 
to prohibit the installation of affected cylinder assemblies into any 
engine.

Regulatory Flexibility Determination

    The Regulatory Flexibility Act of 1980 (Pub. L. 96-354) (RFA) 
establishes as a principle of regulatory issuance that agencies shall 
endeavor, consistent with the objective of the rule and of applicable 
statutes, to fit regulatory and informational requirements to the scale 
of the businesses, organizations, and governmental jurisdictions 
subject to regulation.
    To achieve that principle, the RFA requires agencies to solicit and 
consider flexible regulatory proposals and to explain the rationale for 
their actions. The RFA covers a wide-range of small entities, including 
small businesses, not-for-profit organizations, and small governmental 
jurisdictions.
    Agencies must perform a review to determine whether a proposed or 
final rule will have a significant economic impact on a substantial 
number of small entities. If the agency determines that it will, the 
agency must prepare a regulatory flexibility analysis as described in 
the Act. Based on the comments received following publication of the 
NPRM, we have completed an IRFA and request comments from affected 
small entities. The purpose of this analysis is to identify the number 
of small entities affected, assess the economic impact of the proposed 
regulation on them, and consider less burdensome alternatives and still 
meet the agency's statutory objectives.

Part 135 Operators

    The U.S. Small Business Administration (SBA) classifies businesses 
as small based on size standards, typically expressed as number of 
employees. The FAA identified 609 part 135 operators that meet the SBA 
definition of a small entity (entities with 1,500 or fewer employees) 
out of the 610 part 135 operators affected by this proposed rule. We 
consider this a substantial number of small entities.
    For the 609 part 135 small operators, we estimate costs that range 
between $14 thousand and $1.2 million for adopting this AD. We also 
estimated the value of their aircraft, which ranges between $22 
thousand and $21 million. Using the preceding information, the FAA 
estimates that the ratio of annualized cost to asset value are higher 
than 5 percent for 432 part 135 operators.

Smaller Air Services Businesses

    We estimate that more than 5,000 smaller air services businesses 
would be affected by this proposed rule. We consider this a substantial 
number of small entities. For each of these entities, we estimated 
costs of about $14 thousand although we were unable to estimate their 
asset value.

Initial Regulatory Flexibility Analysis

    Under Section 603(b) of the RFA, the initial analysis must address:
    (1) Description of reasons the agency is considering the action;
    (2) Statement of the legal basis and objectives for the proposed 
rule;
    (3) Description of the record keeping and other compliance 
requirements of the proposed rule;
    (4) All federal rules that may duplicate, overlap, or conflict with 
the proposed rule;
    (5) Description and an estimated number of small entities to which 
the proposed rule will apply; and
    (6) Describe alternatives considered.
    A brief description of each of these criteria is discussed below. 
The complete IRFA can be found in the AD docket on the Internet at 
http://www.regulations.gov/#!searchResults;rpp=25;po=0;s=FAA-2012-0002.

1. A Description of the Reasons Action by the Agency Is Being 
Considered

    This proposed AD was prompted by failure reports of multiple 
cylinder head-to-barrel separations and cracked and leaking aluminum 
cylinder heads.

2. Objectives of, and Legal Basis for, the Proposed Rule

    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.

3. A Description of and an Estimate of the Number of Small Entities to 
Which the Proposed Rule Will Apply

    The FAA identified 432 small part 135 operators on which the rule 
will have a significant economic impact. We estimate that these small 
part 135 operators have assets valued between $22 thousand and $21 
million.

4. Reporting, Record Keeping, and Other Compliance Requirements of the 
Proposed Rule

    Public reporting for this collection of information is estimated to 
be approximately 5 minutes per response, including the time for 
reviewing instructions, completing and reviewing the collection of 
information. Total paperwork costs range between $7 and $623 per small 
entity.

5. Duplicative, Overlapping, or Conflicting Federal Rules

    The FAA is unaware of any Federal rules that duplicate, overlap, or 
conflict with this rule.

6. Significant Alternatives to the Proposed Rule

    We have considered the following alternatives:
    (1) Do nothing--This option is not acceptable due to the number of 
failures of ECi cylinder head assemblies and the consequences of the 
failures.
    (2) Periodic inspections only (no forced removals)--Though the 
National Transportation Safety Board recommends this option, we do not 
find it acceptable. The rate of crack growth to failure is unknown, but 
has shown that it can be more rapid than the intervals of part 43 
mandated inspections. Further, failure events tend to group in both low 
time (<500 hr) failure events and high time (>1000 hr) failure events.
    (3) Forced removals only (no periodic inspections)--We do not find 
that this option is acceptable. Failure events may still occur at times 
other than the low and high times groups described above, and periodic 
inspections may find impending failures.

Comments Invited

    We invite you to send any written relevant data, views, or 
arguments about this rulemaking. Send your comments to an address 
listed under the ADDRESSES section. Include ``Docket No. FAA-2012-0002; 
Directorate Identifier 2011-NE-42-AD'' at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of this rulemaking action. 
The most helpful comments will reference a specific portion of the IRFA 
or related rulemaking document, explain the reason for any recommended 
change, and include supporting data.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will address all comments in the final rule including those already in 
the AD docket from the NPRM. We will also post a report summarizing 
each substantive verbal contact we receive about the proposed AD.
