Discussion
pwalker on PROD1PC71 with PROPOSALS
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Community, has issued EASA AD No.
2008–0095, dated May 16, 2008
(referred to after this as ‘‘the MCAI’’), to
correct an unsafe condition for the
specified products. The MCAI states:
A DG–500MB experienced, after the engine
shutdown, an uncommanded retraction of its
powerplant.
Investigations revealed that some bolts of
the extension retraction mechanism had
fractured because of fatigue stress due to
increasing push-pull loads acting on
incorrectly tightened screws.
This condition, if not corrected, could lead
to damage of the propeller and the fuselage,
thereby reducing the structural integrity of
the sailplane.
VerDate Aug<31>2005
16:17 Jun 12, 2008
Jkt 214001
To address this unsafe condition, this
Airworthiness Directive mandates the
replacement of eight bolts, the four
connecting the fork 5M203 to the 5M204
adapter and those connecting the adapter
5M204 to the spindle drive, by new ones of
higher strength and a rework of the coupling
of the 5M203 fork to the 5M204 adapter as
well as the coupling of the 5M204 adapter to
the spindle drive, by glueing the parts
together, in addition to the pre-existing bolts.
You may obtain further information
by examining the MCAI in the AD
docket.
Relevant Service Information
DG Flugzeugbau GmbH has issued
Technical Note No. 843/27, dated April
14, 2008. 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.
Based on these figures, we estimate
the cost of the proposed AD on U.S.
operators to be $1,212, or $303 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 have reviewed the MCAI and
related service information and, in
general, agree with their substance. But
we might have found it necessary to use
different words from those in the MCAI
to ensure the AD is clear for U.S.
operators and is enforceable. In making
these changes, we do not intend to differ
substantively from the information
provided in the MCAI and related
service information.
We might also have proposed
different actions in this AD from those
in the MCAI in order to follow FAA
policies. Any such differences are
highlighted in a NOTE within the
proposed AD.
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); and
3. 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.
We prepared a regulatory evaluation
of the estimated costs to comply with
this proposed AD and placed it in the
AD docket.
Costs of Compliance
List of Subjects in 14 CFR Part 39
We estimate that this proposed AD
would affect 4 products of U.S. registry.
We also estimate that it would take
about 3 work-hours per product to
comply with the basic requirements of
this proposed AD. The average labor
rate is $80 per work-hour. Required
parts would cost about $63 per product.

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the
products listed above. 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 DG-500MB experienced, after the engine shutdown, an
uncommanded retraction of its powerplant.
Investigations revealed that some bolts of the extension
retraction mechanism had fractured because of fatigue stress due to
increasing push-pull loads acting on incorrectly tightened screws.
This condition, if not corrected, could lead to damage of the
propeller and the fuselage, thereby reducing the structural
integrity of the sailplane.
The proposed AD would require actions that are intended to address
the unsafe condition described in the MCAI.

Discussion
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued EASA
AD No. 2008-0095, dated May 16, 2008 (referred to after this as ``the
MCAI''), to correct an unsafe condition for the specified products. The
MCAI states:
A DG-500MB experienced, after the engine shutdown, an
uncommanded retraction of its powerplant.
Investigations revealed that some bolts of the extension
retraction mechanism had fractured because of fatigue stress due to
increasing push-pull loads acting on incorrectly tightened screws.
This condition, if not corrected, could lead to damage of the
propeller and the fuselage, thereby reducing the structural
integrity of the sailplane.
To address this unsafe condition, this Airworthiness Directive
mandates the replacement of eight bolts, the four connecting the
fork 5M203 to the 5M204 adapter and those connecting the adapter
5M204 to the spindle drive, by new ones of higher strength and a
rework of the coupling of the 5M203 fork to the 5M204 adapter as
well as the coupling of the 5M204 adapter to the spindle drive, by
glueing the parts together, in addition to the pre-existing bolts.
You may obtain further information by examining the MCAI in the AD
docket.
Relevant Service Information
DG Flugzeugbau GmbH has issued Technical Note No. 843/27, dated
April 14, 2008. 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.
Differences Between This Proposed AD and the MCAI or Service
Information
We have reviewed the MCAI and related service information and, in
general, agree with their substance. But we might have found it
necessary to use different words from those in the MCAI to ensure the
AD is clear for U.S. operators and is enforceable. In making these
changes, we do not intend to differ substantively from the information
provided in the MCAI and related service information.
We might also have proposed different actions in this AD from those
in the MCAI in order to follow FAA policies. Any such differences are
highlighted in a NOTE within the proposed AD.
Costs of Compliance
We estimate that this proposed AD would affect 4 products of U.S.
registry. We also estimate that it would take about 3 work-hours per
product to comply with the basic requirements of this proposed AD. The
average labor rate is $80 per work-hour. Required parts would cost
about $63 per product.
Based on these figures, we estimate the cost of the proposed AD on
U.S. operators to be $1,212, or $303 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 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); and
3. 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.
We prepared a regulatory evaluation of the estimated costs to
comply with this proposed AD and placed it in the AD docket.

The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
[[Page 33745]]
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-2008-0649; Directorate
Identifier 2008-CE-038-AD.
Comments Due Date
(a) We must receive comments by July 14, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to DG-500MB powered sailplanes, all serial
numbers, certificated in any category.
Subject
(d) Air Transport Association of America (ATA) Code 71: Power
Plant.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
A DG-500MB experienced, after the engine shutdown, an
uncommanded retraction of its powerplant.
Investigations revealed that some bolts of the extension
retraction mechanism had fractured because of fatigue stress due to
increasing push-pull loads acting on incorrectly tightened screws.
This condition, if not corrected, could lead to damage of the
propeller and the fuselage, thereby reducing the structural
integrity of the sailplane.
To address this unsafe condition, this Airworthiness Directive
mandates the replacement of eight bolts, the four connecting the
fork 5M203 to the 5M204 adapter and those connecting the adapter
5M204 to the spindle drive, by new ones of higher strength and, a
rework of the coupling of the 5M203 fork to the 5M204 adapter as
well as the coupling of the 5M204 adapter to the spindle drive, by
glueing the parts together, in addition to the pre-existing bolts.
Actions and Compliance
(f) Unless already done, within the next 30 days after the
effective date of this AD, modify the spindle drive assembly in
accordance with DG Flugzeugbau GmbH Technical Note No. 843/27, dated
April 14, 2008.
FAA AD Differences
Note: This AD differs from the MCAI and/or service information
as follows: No differences.
Other FAA AD Provisions
(g) 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: Greg Davison, Aerospace Engineer, FAA, Small
Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri
64106; telephone: (816) 329-4130; fax: (816) 329-4090. Before using
any approved AMOC on any powered sailplane 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, under the provisions of the Paperwork Reduction Act (44
U.S.C. 3501 et seq.), the Office of Management and Budget (OMB) has
approved the information collection requirements and has assigned
OMB Control Number 2120-0056.
