ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
The FAA proposes to adopt a
new airworthiness directive (AD) for
certain DG Flugzeugbau GmbH Models
SUMMARY:
VerDate Aug<31>2005
17:08 Oct 04, 2005
Jkt 208001
DG–800B and DG–500MB sailplanes.
This proposed AD would require you to
modify the connection of the starter ring
gear to the lower drive belt pulley
adapter. This proposed AD results from
mandatory continuing airworthiness
information (MCAI) issued by the
airworthiness authority for Germany.
We are issuing this proposed AD to
prevent the bolts currently used to
connect the starter ring gear to the drive
belt pulley adapter from shearing off
and the bolt heads falling into the
engine compartment. Failure of this
connection could render the engine
inoperative. Consequently, this failure
could lead to loss of control of the
sailplane.
We must receive any comments
on this proposed AD by November 9,
2005.

Discussion
What events have caused this
proposed AD? The Luftfahrt-Bundesamt
(LBA), which is the airworthiness
authority for Germany, recently notified
FAA that an unsafe condition may exist
on certain DG Flugzeugbau GmbH
E:\FR\FM\05OCP1.SGM
05OCP1
58108
Federal Register / Vol. 70, No. 192 / Wednesday, October 5, 2005 / Proposed Rules
Models DG–800B and DG–500MB
sailplanes. The LBA reports that sheared
off bolt heads have been found in the
engine compartment of approximately
20 of the specified sailplanes. These
bolts connect the starter ring gear to the
lower drive belt pulley adapter. Failure
of this connection could render the
engine inoperative.
What is the potential impact if FAA
took no action? The bolts currently used
to connect the starter ring gear to the
drive belt pulley adapter may shear off
and the bolt heads could fall into the
engine compartment. Failure of this
connection could render the engine
inoperative. Consequently, this failure
could lead to loss of control of the
sailplane.
Is there service information that
applies to this subject? DG-Flugzeugbau
GmbH has issued Working Instruction
No. 1 for TN 873/30, dated June 9, 2004;
and Technical Note No. 873/30 and No.
843/22, approved by LBA on June 29,
2004, and approved by the European
Aviation Safety Agency on July 9, 2004.
What are the provisions of this service
information? The service information
includes procedures for:
—Removing the starter ring gear
assembly with adapter and lower
pulley;
—Modifying the connection area where
the bolts connect the starter ring gear
to the lower drive belt pulley adapter;
and
—Reinstalling the starter ring gear
assembly with the adapter and lower
pulley.
What action did the LBA take? The
LBA classified this service information
as mandatory and issued German AD
Number D–2004–347, dated July 2,
2004, to ensure the continued
airworthiness of these sailplanes in
Germany.
Did the LBA inform the United States
under the bilateral airworthiness
agreement? These DG Flugzeugbau
GmbH Models DG–800B and DG–
500MB sailplanes are manufactured in
Germany and are type-certificated for
operation in the United States under the
provisions of section 21.29 of the
Federal Aviation Regulations (14 CFR
21.29) and the applicable bilateral
airworthiness agreement.
Under this bilateral airworthiness
agreement, the LBA has kept us
informed of the situation described
above.
FAA’s Determination and Requirements
of This Proposed AD
What has FAA decided? We have
examined the LBA’s findings, reviewed
all available information, and
determined that AD action is necessary
for products of this type design that are
certificated for operation in the United
States.
Since the unsafe condition described
previously is likely to exist or develop
on other DG Flugzeugbau GmbH Models
DG–800B and DG–500MB sailplanes of
the same type design that are registered
in the United States, we are proposing
AD action to prevent the bolts currently
used to connect the starter ring gear to
the drive belt pulley adapter from
shearing off and the bolt heads falling
into the engine compartment. Failure of
this connection could render the engine
inoperative. Consequently, this failure
could lead to loss of control of the
sailplane.
What would this proposed AD
require? This proposed AD would
require you to incorporate the actions in
the previously-referenced service
information.
How does the revision to 14 CFR part
39 affect this proposed AD? On July 10,
2002, we published a new version of 14
CFR part 39 (67 FR 47997, July 22,
2002), which governs FAA’s AD system.
This regulation now includes material
that relates to altered products, special
flight permits, and alternative methods
of compliance. This material previously
was included in each individual AD.
Since this material is included in 14
CFR part 39, we will not include it in
future AD actions.
Costs of Compliance
How many sailplanes would this
proposed AD impact? We estimate that
this proposed AD affects 7 sailplanes in
the U.S. registry.
What would be the cost impact of this
proposed AD on owners/operators of the
affected sailplanes? We estimate the
following costs to do this proposed
modification:
Labor cost
Parts
cost
Total cost per
sailplane
Total cost on
U.S. operators
3 workhours × $65 = $195 ......................................................................................................................
$21
$216
$1,512
Authority for This Rulemaking
What authority does FAA have for
issuing this rulemaking action? 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
VerDate Aug<31>2005
17:08 Oct 04, 2005
Jkt 208001
that is likely to exist or develop on
products identified in this AD.
Regulatory Findings
Would this proposed AD impact
various entities? We have 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.
Would this proposed AD involve a
significant rule or regulatory action? For
the reasons discussed above, I certify
that this proposed AD:
1. Is not a ‘‘significant regulatory
action’’ under Executive Order 12866;
PO 00000
Frm 00025
Fmt 4702
Sfmt 4702
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 summary of the costs
to comply with this proposed AD (and
other information as included in the
Regulatory Evaluation) and placed it in
the AD Docket. You may get a copy of
this summary by sending a request to us
at the address listed under ADDRESSES.
Include ‘‘AD Docket FAA–2005–22206;
Directorate Identifier 2005–CE–45–AD’’
in your request.

certificated for operation in the United States under the provisions of
section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and
the applicable bilateral airworthiness agreement.
Under this bilateral airworthiness agreement, the LBA has kept us
informed of the situation described above.
FAA's Determination and Requirements of This Proposed AD
What has FAA decided? We have examined the LBA's findings, reviewed
all available information, and determined that AD action is necessary
for products of this type design that are certificated for operation in
the United States.
Since the unsafe condition described previously is likely to exist
or develop on other DG Flugzeugbau GmbH Models DG-800B and DG-500MB
sailplanes of the same type design that are registered in the United
States, we are proposing AD action to prevent the bolts currently used
to connect the starter ring gear to the drive belt pulley adapter from
shearing off and the bolt heads falling into the engine compartment.
Failure of this connection could render the engine inoperative.
Consequently, this failure could lead to loss of control of the
sailplane.
What would this proposed AD require? This proposed AD would require
you to incorporate the actions in the previously-referenced service
information.
How does the revision to 14 CFR part 39 affect this proposed AD? On
July 10, 2002, we published a new version of 14 CFR part 39 (67 FR
47997, July 22, 2002), which governs FAA's AD system. This regulation
now includes material that relates to altered products, special flight
permits, and alternative methods of compliance. This material
previously was included in each individual AD. Since this material is
included in 14 CFR part 39, we will not include it in future AD
actions.
Costs of Compliance
How many sailplanes would this proposed AD impact? We estimate that
this proposed AD affects 7 sailplanes in the U.S. registry.
What would be the cost impact of this proposed AD on owners/
operators of the affected sailplanes? We estimate the following costs
to do this proposed modification:
------------------------------------------------------------------------
Parts Total cost per Total cost on
Labor cost cost sailplane U.S. operators
------------------------------------------------------------------------
3 workhours x $65 = $195.... $21 $216 $1,512
------------------------------------------------------------------------
Authority for This Rulemaking
What authority does FAA have for issuing this rulemaking action?
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 AD.
Regulatory Findings
Would this proposed AD impact various entities? We have 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.
Would this proposed AD involve a significant rule or regulatory
action? For the reasons discussed above, I certify that this proposed
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); 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 summary of the costs to comply with this proposed AD
(and other information as included in the Regulatory Evaluation) and
placed it in the AD Docket. You may get a copy of this summary by
sending a request to us at the address listed under ADDRESSES. Include
``AD Docket FAA-2005-22206; Directorate Identifier 2005-CE-45-AD'' in
your request.

The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the Federal Aviation Administration 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
airworthiness directive (AD):
DG Flugzeugbau GmbH: Docket No. FAA-2005-22206; Directorate
Identifier 2005-CE-45-AD.
When Is the Last Date I Can Submit Comments on This Proposed AD?
(a) We must receive comments on this proposed airworthiness
directive (AD) by November 9, 2005.
What Other ADs Are Affected by This Action?
(b) None.
What Sailplanes Are Affected by This AD?
(c) This AD affects the following airplane models and serial
numbers that are certificated in any category:
------------------------------------------------------------------------
Model Serial numbers
------------------------------------------------------------------------
(1) DG-800B....................... All serial numbers up to and
including 8-260, with the exception
of 8-247 and 8-258; and
(2) DG-500MB...................... All serial numbers up to and
including 5E220B15, with the
exception of 5E190B5.
------------------------------------------------------------------------
What Is the Unsafe Condition Presented in This AD?
(d) This AD is the result of bolt failure in the connection of
the starter ring gear to the drive belt pulley adapter. The bolt
heads may shear off and the bolt heads could fall into the engine
compartment. The actions specified in this AD are intended to
prevent the bolts currently used to connect the starter ring gear to
the drive belt pulley adapter from shearing off and the bolt heads
falling into the engine compartment. Failure of this connection
could render the engine inoperative. Consequently, this failure
could lead to loss of control of the sailplane.
What Must I Do To Address This Problem?
