14 CFR Part 39

[Docket No. FAA-2012-1250; Directorate Identifier 2012-CE-043-AD; 
Amendment 39-17344; AD 2013-03-09]

Airworthiness Directives; DG Flugzeugbau GmbH Gliders

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

ACTION: Final rule.

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

SUMMARY: 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.

DATES: 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.

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. 
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.

Comments

    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.

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 (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.

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.

Examining the AD Docket

    You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Management Facility 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The AD docket contains the NPRM, the regulatory evaluation, 
any comments received, and other information. The

(e) Reason

    This AD was prompted by mandatory continuing airworthiness 
information (MCAI) originated 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 within the propeller shaft, most likely caused by a 
manufacturing error. We are issuing this AD to prevent failure of 
the propeller shaft and detachment of the propeller, which could 
result in reduced control of the aircraft or injury to persons on 
the ground.

(f) Actions and Compliance

    Unless already done, do the following actions:
    (1) Within 25 hours time-in-service (TIS) after March 19, 2013 
(the effective date of this AD) or 6 months after March 19, 2013 
(the effective date of this AD), whichever occurs first, remove the 
propeller pulley assembly (module) from the engine and inspect the 
transition region of the part number (P/N) 20 31 211 shaft following 
the Actions section of Solo Kleinmotoren GmbH Service Bulletin Nr. 
4603-13, Issue 1, dated September 24, 2012.
    (2) If, during the inspection required by paragraph (f)(1) of 
this AD, cracks are detected in the P/N 20 31 211 shaft, before 
further flight, do the following:
    (i) Replace the P/N 20 31 211 shaft with an airworthy P/N 20 31 
211 shaft; or
    (ii) Replace the propeller pulley assembly (module) with an 
airworthy propeller pulley assembly (module).

(g) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
Standards Office, FAA, has the authority to approve AMOCs for this 
AD, if requested using the procedures found in 14 CFR 39.19. Send
