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.
