Airworthiness Directives; DG Flugzeugbau GmbH Gliders
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to adopt a new airworthiness directive (AD) for DG
Flugzeugbau GmbH Model DG-1000T gliders equipped with Solo Kleinmotoren
Model 2350 C engines. This proposed AD results from 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 of the propeller shaft, most likely
caused by a manufacturing error. We are issuing this proposed AD to
require actions to address the unsafe condition on these products.

Discussion
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued AD
No.: 2012-0197, dated September 25, 2012 (referred to after this as
``the MCAI''), 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.
You may obtain further information by examining the MCAI in the AD
docket.
Relevant Service Information
Solo Kleinmotoren GmbH has issued Service Bulletin Nr. 4603-13,
Issue 1, dated September 24, 2012. The actions described in this
service information are intended to correct the unsafe condition
identified in the MCAI.
FAA's Determination and Requirements of the Proposed AD
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with this State of Design Authority, they
have notified us of the unsafe condition described in the MCAI and
service information referenced above. We are proposing this AD because
we evaluated all information and determined the unsafe condition exists
and is likely to exist or develop on other products of the same type
design.
[[Page 71360]]
Costs of Compliance
We estimate that this proposed 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 proposed 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 proposed 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 proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 proposed
regulation:
(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.

The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
2. The FAA amends Sec. 39.13 by adding the following new AD:
DG Flugzeugbau GmbH: Docket No. FAA-2012-1250; Directorate
Identifier 2012-CE-043-AD.
(a) Comments Due Date
We must receive comments by January 14, 2013.
(b) Affected ADs
None.
(c) Applicability
This AD applies to DG Flugzeugbau GmbH Model DG-1000T gliders
equipped with Solo Kleinmotoren Model 2350 C engines, all serial
numbers, certificated in any category.
(d) Subject
Air Transport Association of America (ATA) Code 72: Engine.
(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 the effective
date of this AD or 6 months after 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 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
information to ATTN: 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:.
Before using any approved AMOC on any airplane to which the AMOC
applies, notify your appropriate principal inspector (PI) in the FAA
Flight Standards District Office (FSDO), or lacking a PI, your local
FSDO.
(2) Airworthy Product: For any requirement in this AD to obtain
corrective actions from a manufacturer or other source, use these
actions if they are FAA-approved. Corrective actions are considered
FAA-approved if they are approved by the State of Design Authority
(or their delegated agent). You are required to assure the product
is airworthy before it is returned to service.
(3) Reporting Requirements: For any reporting requirement in
this AD, a federal agency may not conduct or sponsor, and a person
is not required to respond to, nor shall a person be subject to a
penalty for failure to comply with a collection of information
subject to the requirements of the Paperwork Reduction Act unless
that collection of information displays a current valid OMB Control
Number. The OMB Control Number for this information collection is
2120-0056. 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. All responses to this collection of
information are mandatory. Comments concerning the accuracy of this
burden and suggestions for reducing the burden should be directed to
the FAA at: 800 Independence Ave. SW., Washington, DC 20591, Attn:
Information Collection Clearance Officer, AES-200.
