Federal Aviation
Administration (FAA), Department of
Transportation (DOT).
ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
We propose to adopt a new
airworthiness directive (AD) for
Diamond Aircraft Industries Model H–
36 ‘‘DIMONA’’ powered sailplanes. 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:
SUMMARY:
A report has been received of a failed air
brake control system torsion tube on a
Diamond (formerly Hoffman) H 36 powered
sailplane. The results of the subsequent
investigation show that the failure was due
to corrosion damage.
This condition, if not detected and
corrected, may lead to failure of the air brake
control system in flight, resulting in reduced
control of the aeroplane.
The proposed AD would require actions
that are intended to address the unsafe
condition described in the MCAI.
DATES: We must receive comments on
this proposed AD by September 22,
2011.
You may send comments by
any of the following methods:

Discussion
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Community, has issued AD No. 2011–
0110, dated June 16, 2011 (referred to
after this as ‘‘the MCAI’’), to correct an
unsafe condition for the specified
products. The MCAI states:
E:\FR\FM\08AUP1.SGM
08AUP1
48048
Federal Register / Vol. 76, No. 152 / Monday, August 8, 2011 / Proposed Rules
A report has been received of a failed air
brake control system torsion tube on a
Diamond (formerly Hoffman) H 36 powered
sailplane. The results of the subsequent
investigation show that the failure was due
to corrosion damage.
This condition, if not detected and
corrected, may lead to failure of the air brake
control system in flight, resulting in reduced
control of the aeroplane.
To address this unsafe condition, Diamond
published Mandatory Service Bulletin (MSB)
36–105, containing instructions to test and
inspect the air brake control system torsion
tube for corrosion damage and, depending on
findings, the application of anticorrosive
agent to the inside of the torsion tube, or
replacement of the torsion tube with a
serviceable part.
For the reasons described above, this new
AD requires repetitive tests and inspections
of the air brake control system torsion tube
and applicable corrective actions, depending
on findings.
You may obtain further information by
examining the MCAI in the AD docket.
Relevant Service Information
Diamond Aircraft Industries GmbH
has issued Service Bulletin No. MSB
36–105/1, dated May 2, 2011, and Work
Instruction WI–MSB 36–105, dated
April 21, 2011. The actions described in
this service information are intended to
correct the unsafe condition identified
in the MCAI.
emcdonald on DSK2BSOYB1PROD with PROPOSALS
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
VerDate Mar<15>2010
18:42 Aug 05, 2011
Jkt 223001
highlighted in a NOTE within the
proposed AD.
Costs of Compliance
We estimate that this proposed AD
will affect 9 products of U.S. registry.
We also estimate that it would take
about 4.5 work-hours 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 $172 per
product.
Based on these figures, we estimate
the cost of the proposed AD on U.S.
operators to be $4,990.50, or $554.50 per
product.
In addition, we estimate that any
necessary follow-on actions would take
about 5 work-hours and require parts
costing $275, for a cost of $700 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); and
PO 00000
Frm 00004
Fmt 4702
Sfmt 4702
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.

that applies to Model L–1011–385–1, L–
1011–385–1–14, and L–1011–385–1–15
airplanes. The existing AD currently
requires implementation of a
Supplemental Inspection Document
(SID) program of structural inspections
to detect fatigue cracking, and repair, if
necessary, to ensure continued
airworthiness of these airplanes as they
approach the manufacturer’s original
fatigue design life goal. Since we issued
that AD, an evaluation by the
manufacturer of usage and flight data
provided additional information about
certain Structurally Significant Details
(SSDs) where fatigue damage is likely to
occur. This proposed AD would add
airplanes to the applicability, change
certain inspection thresholds, add three
new SSDs, and remove an SSD that has
been addressed by a different AD. We
are proposing this AD to prevent fatigue
cracking that could compromise the
structural integrity of these airplanes.
DATES: We must receive comments on
this proposed AD by September 22,

will also post a report summarizing each substantive verbal contact we
receive about this proposed AD.
Discussion
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued AD
No. 2011-0110, dated June 16, 2011 (referred to after this as ``the
MCAI''), to correct an unsafe condition for the specified products. The
MCAI states:
[[Page 48048]]
A report has been received of a failed air brake control system
torsion tube on a Diamond (formerly Hoffman) H 36 powered sailplane.
The results of the subsequent investigation show that the failure
was due to corrosion damage.
This condition, if not detected and corrected, may lead to
failure of the air brake control system in flight, resulting in
reduced control of the aeroplane.
To address this unsafe condition, Diamond published Mandatory
Service Bulletin (MSB) 36-105, containing instructions to test and
inspect the air brake control system torsion tube for corrosion
damage and, depending on findings, the application of anticorrosive
agent to the inside of the torsion tube, or replacement of the
torsion tube with a serviceable part.
For the reasons described above, this new AD requires repetitive
tests and inspections of the air brake control system torsion tube
and applicable corrective actions, depending on findings.
You may obtain further information by examining the MCAI in the AD
docket.
Relevant Service Information
Diamond Aircraft Industries GmbH has issued Service Bulletin No.
MSB 36-105/1, dated May 2, 2011, and Work Instruction WI-MSB 36-105,
dated April 21, 2011. 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 will affect 9 products of U.S.
registry. We also estimate that it would take about 4.5 work-hours 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 $172 per product.
Based on these figures, we estimate the cost of the proposed AD on
U.S. operators to be $4,990.50, or $554.50 per product.
In addition, we estimate that any necessary follow-on actions would
take about 5 work-hours and require parts costing $275, for a cost of
$700 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); 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:
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:
Diamond Aircraft Industries: Docket No. FAA-2011-0811; Directorate
Identifier 2011-CE-026-AD.
Comments Due Date
(a) We must receive comments by September 22, 2011.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Diamond Aircraft Industries Model H-36
``DIMONA'' powered sailplanes, all serial numbers, certificated in
any category.
Subject
(d) Air Transport Association of America (ATA) Code 27: Flight

Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
A report has been received of a failed air brake control system
torsion tube on a Diamond (formerly Hoffman) H 36 powered sailplane.
The results of the subsequent investigation show that the failure
was due to corrosion damage.
This condition, if not detected and corrected, may lead to
failure of the air brake control system in flight, resulting in
reduced control of the aeroplane.
To address this unsafe condition, Diamond published Mandatory
Service Bulletin (MSB) 36-105, containing instructions to test and
inspect the air brake control system torsion tube for corrosion
damage and, depending on findings, the application of anticorrosive
agent to the inside of the torsion tube, or replacement of the
torsion tube with a serviceable part.
[[Page 48049]]
For the reasons described above, this new AD requires repetitive
tests and inspections of the air brake control system torsion tube
and applicable corrective actions, depending on findings.
