Federal Aviation Administration (FAA), Department of Transportation (DOT).
We are adopting a new airworthiness directive (AD) for DG Flugzeugbau GmbH Model DG-1000T gliders equipped with Solo Kleinmotoren Model 2350 C engines. 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 a material defect of the propeller shaft, most likely caused by a manufacturing error. We are issuing this AD to require actions to address the unsafe condition on these products.
This AD is effective March 19, 2013.
The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of March 19, 2013.

FOR FURTHER INFORMATION CONTACT:
Jim Rutherford, Aerospace Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329-4165; fax: (816) 329-4090; email: email@example.com.End Further Info End Preamble Start Supplemental Information
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. That NPRM was published in the Federal Register on November 30, 2012 (77 FR 71359). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states:
Two reports have been received of a broken P/N 20 31 211 propeller shaft on a Solo 2350 C engine. The results of the investigation showed that the failures were due to a material defect, most likely caused by a manufacturing error.
This condition, if not detected and corrected, could lead to failure of the shaft and detachment of the propeller from the aeroplane, which, depending on the flight conditions, could result in reduced control of the aeroplane, or injury to persons on the ground.
For the reasons described above, this AD requires a one-time inspection (magnetic particle or dye penetrant) of the affected propeller shafts to detect cracks and, depending on findings, replacement of the propeller pulley assembly (module) with a serviceable module.
We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public.
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 (77 FR 71359, November 30, 2012) for correcting the unsafe condition; and
- Do not add any additional burden upon the public than was already proposed in the NPRM (77 FR 71359, November 30, 2012).
Costs of Compliance
We estimate that this AD will affect 2 products of U.S. registry. We also estimate that it would take about 1 work-hour per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts would cost about $0 per product.
Based on these figures, we estimate the cost of the AD on U.S. operators to be $170, or $85 per product.
In addition, we estimate that any necessary follow-on actions would take about 1 work-hour and require parts costing $197, for a cost of $282 per product. We have no way of determining the number of products that may need these actions.
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.
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.
