Airworthiness Directives; Schempp-Hirth 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
Schempp-Hirth Flugzeugbau GmbH Model Discus 2cT gliders. 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 small cracks which have been found on engine
pylons in the area of the lower engine support that have not been
detected during the standard daily inspection. This condition, if not
detected and corrected, could lead to an engine pylon failure resulting
in loss of control of the glider. We are issuing this AD to require
actions to address the unsafe condition on these products.
DATES: This AD is effective February 15, 2012.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of February 15,
2012.

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 October 21, 2011 (76
FR 65421). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
It has been reported that small cracks on engine pylons, in the
area of the lower engine support, were not detected through the
``standard'' inspection required by the daily inspection
instructions. The cracks were discovered only after having
significantly grown.
This condition, if not detected and corrected, could lead to an
engine pylon failure and consequent damage to the aeroplane or
injury to people on the ground.
For the reasons described above, this AD requires to replace the
daily inspections pages of the Aircraft Flight Manual (AFM) that are
describing the engine pylon inspection instructions, to inspect the
affected engine pylon area in accordance with those instructions,
and the replacement with a newly designed engine pylon in case of
findings.
[[Page 1625]]
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (76 FR 65421, October 21,
2011) or on the determination of the cost to the public.
Conclusion
We reviewed the available data and determined that air safety and
the public interest require adopting the AD as proposed.
Costs of Compliance
We estimate that this AD will affect 3 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.
Based on these figures, we estimate the cost of this AD on U.S.
operators to be $255, or $85 per product.
In addition, we estimate that any necessary follow-on actions would
take about 8 work-hours and require parts costing $1,697, for a cost of
$2,377 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 <a href="http://www.regulations.gov">http://www.regulations.gov</a>; 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 (76 FR 65421, October 21,
2011), the regulatory evaluation, any comments received, and other
information. The street address for the Docket Office (telephone (800)
647-5527) is in the ADDRESSES section. Comments will be available in
the AD docket shortly after receipt.
List of Subjects in 14 CFR Part 39

reference, Safety.
Adoption of the Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
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]
0
2. The FAA amends Sec. 39.13 by adding the following new AD:
2012-01-02 Schempp-Hirth Flugzeugbau: Amendment 39-16913; Docket No.
FAA-2011-1155; Directorate Identifier 2011-CE-032-AD.
(a) Effective Date
This airworthiness directive (AD) becomes effective February 15,
2012.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Schempp-Hirth Flugzeugbau Discus 2cT gliders,
serial numbers 1 through 35, certificated in any category, except
those on which a engine pylon, part number (P/N) M03RT841, is
installed.
(d) Subject
Air Transport Association of America (ATA) Code 54: Nacelles/
Pylons.
(e) Reason
This AD was prompted by small cracks which have been found on
engine pylons in the area of the lower engine support that have not
been detected during the standard daily inspection. This condition,
if not detected and corrected, could lead to an engine pylon failure
resulting in loss of control of the glider. We are issuing this AD
to require actions to address the unsafe condition on these
products.
(f) Actions and Compliance
Unless already done, do the following actions:
(1) Within 30 days after the effective date of this AD, replace
the daily inspection pages of the airplane flight manual following
Schempp-Hirth Flugzeugbau GmbH Technical Note No. 863-20 Revision 1,
dated July 27, 2011. The actions required by this paragraph may be
performed by the owner/operator (pilot) holding at least a private
pilot certificate and must be entered into the aircraft records
showing compliance with this AD in accordance with 14 CFR 43.9
(a)(1)-(4) and 14 CFR 91.417(a)(2)(v). The record must be maintained
as required by 14 CFR 91.417, 121.380, or 135.439. All other actions
in this AD must be done by a properly certificated aircraft
mechanic.
(2) Before further flight after doing the action in paragraph
(f)(1) of this AD and repetitively thereafter at intervals not to
exceed every 12 months, inspect the engine pylon for damage or
cracks, following the daily inspection instructions as amended by
Schempp-Hirth Flugzeugbau GmbH Technical Note No. 863-20 Revision 1,
dated July 27, 2011.
(3) If during the daily inspections in the instructions amended
by Schempp-Hirth Flugzeugbau GmbH Technical Note No. 863-20 Revision
1, dated July 27, 2011, in paragraph (f)(1) of this AD or the
inspections required in paragraph (f)(2) of this AD, any damage or
crack is found on the engine pylon, before further flight, replace
the engine pylon with an engine pylon part number M03RT841 following
Schempp-Hirth Flugzeugbau GmbH Technical Note No. 863-14, dated July
18, 2006.
(g) FAA AD Differences
Note: This AD differs from the MCAI and/or service information
as follows: In addition to the daily pilot inspections of the engine
pylon required by the foreign authority, the FAA also requires an
initial and annual repetitive inspection by a properly certificated
aircraft mechanic.
(h) 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,

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
