Airworthiness Directives; DORNIER LUFTFAHRT GmbH Airplanes

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

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for DORNIER 
LUFTFAHRT GmbH Model 228-212 airplanes. This AD results from mandatory 
continuing airworthiness information (MCAI) issued by an aviation 
authority of another country to identify and correct an unsafe 
condition on an aviation product. The MCAI describes the unsafe 
condition as main landing gear axle failure caused by initial fatigue 
cracking and small pre-damage by corrosion. We are issuing this AD to 
require actions to address the unsafe condition on these products.

DATES: This AD is effective April 1, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of April 1, 
2014.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to add an AD that would apply to DORNIER LUFTFAHRT GmbH Model 
228-212 airplanes. That NPRM was published in the Federal Register on 
November 19, 2013 (78 FR 69320). That NPRM proposed to correct an 
unsafe condition for the specified products and was based on mandatory 
continuing airworthiness information (MCAI) originated by an aviation 
authority of another country. The MCAI states:

    An event of a main landing gear (MLG) axle break during 
touchdown has been reported. The results of the subsequent technical 
investigation indicated that improper restoration of corrosion 
protection was the likely cause of the initial fatigue cracking.
    This condition, if not detected and corrected, could lead to 
failure of the main landing gear axle, possibly resulting in a 
runway excursion with consequent damage to the aeroplane and injury 
to the occupants.
    To address this potential unsafe condition, RUAG Aerospace 
Services GmbH issued Service Bulletin (SB) SB-228-300, Rev. 1.
    For the reason described above, this AD requires a one-time 
inspection of the MLG axle and, depending on findings, 
accomplishment of applicable corrective actions.

The MCAI can be found in the AD docket on the Internet at: http://www.regulations.gov/#!documentDetail;D=FAA-2013-0962-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (78 FR 69320, November 19, 
2013) 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 the 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 (78 FR 69320, November 19, 2013) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (78 FR 69320, November 19, 2013).

Costs of Compliance

    We estimate that this AD would affect 2 products of U.S. registry. 
We also estimate that it would take about 160 work-hours 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 $27,200, or $13,600 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 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.
