2014-07-08 CENTRAIR: Amendment 39-17822; Docket No. FAA-2014-0018; Directorate Identifier 2013-CE-049-AD. 
(a) EFFECTIVE DATE

    This airworthiness directive (AD) becomes effective May 27, 2014.

(b) AFFECTED ADS

    None.

(c) APPLICABILITY

    This AD applies to CENTRAIR Models 101, 101A, 101P, and 101AP gliders,
    all serial numbers, certificated in any category.

(d) SUBJECT

    Air Transport Association of America (ATA) Code 53: Fuselage.

(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  structural  damage to  the
    fuselage. We  are issuing  this AD  to detect  and correct  structural
    damage not  identified during  routine maintenance  inspections, which
    could lead to reduced structural integrity of the glider.

(f) ACTIONS AND COMPLIANCE

    Unless already  done, do  the following  actions in  paragraphs (f)(1)
    through (f)(3) of this AD:

(1) Within 25 days after May 27, 2014 (the effective date of this AD)  and
    repetitively thereafter at  intervals not to  exceed every 12  months,
    inspect all  fuselage frames  and ribs  following the  instructions in
    Societe Nouvelle CENTRAIR Mandatory Service Bulletin 101-06,  Revision
    1, dated August 5, 2013.

(2) If  structural  damage  is  detected during any inspection required by
    paragraph (f)(1) of  this AD, before  further flight, contact  Societe
    Nouvelle CENTRAIR at the address specified in paragraph (i) of this AD
    to obtain FAA-approved  repair instructions approved  specifically for
    this AD,  and before  further flight,  repair the  glider using  these
    repair instructions.

(3) Accomplishment of  a  repair,  as required by paragraph (f)(2) of this
    AD, does not constitute terminating action for the inspection required
    by paragraph (f)(1) of this AD.

Note 1 to paragraph  (f) of this AD: We recommend that  you  also  inspect
the fuselage frames and ribs after the occurrence of any of the  following
events following the instructions  in Societe Nouvelle CENTRAIR  Mandatory
Service Bulletin 101-06,  Revision 1, dated  August 5, 2013:  Landing with
retracted gear, landing gear retraction during landing run, ground looping
during take-off or landing, hard landing, or damage of internal  structure
of the  fuselage. If  structural damage  is detected  during any  of these
inspections, we  recommend you  contact Societe  Nouvelle CENTRAIR  at the
address specified  in paragraph  (i) of  this AD  for FAA-approved  repair
instructions.

(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 re-
    quested 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;  tele-
    phone: (816) 329-4165; fax: (816) 329-4090; email: jim.rutherford@faa.
    gov.  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.

PREAMBLE 

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).

ACTION: Final rule.

SUMMARY: We are adopting a new airworthiness directive (AD) for
Centrair Model 101, 101A, 101AP, and 101P 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 structural damage to the fuselage. We are issuing this AD
to require actions to address the unsafe condition on these products.

DATES: This AD is effective May 27, 2014.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of May 27, 2014.

SUPPLEMENTARY INFORMATION:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would apply to Centrair Model 101, 101A,
101AP, and 101P airplanes. The NPRM was published in the Federal
Register on January 15, 2014 (79 FR 2593). The NPRM proposed to correct
an unsafe condition for the specified products and was based on
mandatory continuing airworthiness information (MCAI) originated by an
aviation authority of another country. The MCAI states:

Occurrences of structural damage were reported on several
Centrair 101 sailplane fuselage. The results of the subsequent
investigations identified that these findings were accidental damage
related and not identified in time during routine maintenance, due
to inadequate maintenance instructions.
This condition, if not detected and corrected, could reduce the
structural integrity of the sailplane.
To address this potential unsafe condition,
Societe Nouvelle (SN) Centrair issued Service Bulletin
(SB) 101-06 to provide instructions for structural inspections and
Direction Generale de l'Aviation Civile (DGAC) of
France issued AD 85-21-(A) to mandate the fuselage inspections
described in that SB.
Since that AD was issued, SN Centrair issued SB 101-06 at
revision (rev.) 1 to provide improved instructions to identify
accidental structural damages.
For the reasons described above, this AD retains the
requirements of DGAC France AD 85-21-(A), which is superseded, but
requires accomplishment of those fuselage structural inspections in
accordance with improved instructions.

The MCAI can be found in the AD docket on the Internet at: http://www.regulations.gov/#!documentDetail;D=FAA-2014-0018-0002.

Comments

We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (79 FR 2593, January 15,
2014) or on the determination of the cost to the public.

Conclusion

We reviewed the relevant data and determined that air safety and
the public interest require adopting the AD as proposed except for
minor editorial changes. We have determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM (79 FR 2593, January 15, 2014) for correcting the unsafe
condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.

Costs of Compliance

We estimate that this AD will affect 43 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 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 $10,965, or $255 per product.
Since there are currently no repair instructions available if
discrepancies are found during the required inspections, we have no way
of determining the number of products that may need follow-on actions
or what the cost per product would be.

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.
