14 CFR Part 39
[Docket No. FAA-2004-19616; Directorate Identifier 2004-CE-38-AD;
Amendment 39-14058; AD 2005-08-06]
RIN 2120-AA64
Airworthiness Directives; CENTRAIR 101 Series Gliders
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA adopts a new airworthiness directive (AD) for all
CENTRAIR 101 series gliders with other than elevator or aileron part
number (P/N) SY991A hinge pins installed. This AD requires you to
replace any installed elevator or aileron hinge pins that are not P/N
SY991A hinge pins with P/N SY991A pins. This AD results from mandatory
continuing airworthiness information (MCAI) issued by the airworthiness
authority for France. We are issuing this AD to replace incorrectly
heat-treated elevator or aileron hinge pins, which could result in
failure of the elevator or ailerons. Such failure during takeoff,
landing, or flight operations could lead to loss of glider control.
DATES: This AD becomes effective on June 2, 2005.
As of June 2, 2005, the Director of the Federal Register approved
the incorporation by reference of certain publications listed in the
regulation.

SUPPLEMENTARY INFORMATION:
Discussion
What events have caused this proposed AD? The Direction
G[eacute]n[eacute]rale de l'Aviation Civile (DGAC), which is the
airworthiness authority for France, recently notified FAA that an
unsafe condition may exist on all CENTRAIR 101 series gliders. The DGAC
reports occurrences of improperly heat-treated aileron and elevator
hinge pins installed on the CENTRAIR 101 series gliders. Incorrectly
heat-treated elevator or aileron hinge pins could result in
longitudinal cracks that cause failure of the elevator or ailerons.
CENTRAIR has made available new hinge pins (part number (P/N) SY991A)
to replace any incorrectly heat-treated elevator or aileron hinge pins
or hinge pins with longitudinal cracks.
What is the potential impact if FAA took no action? Failure of the
elevator or ailerons during takeoff, landing, or flight operations
could lead to loss of glider control.
Has FAA taken any action to this point? We issued a proposal to
amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to
include an AD that would apply to all CENTRAIR 101 series gliders with
other than elevator or aileron part number (P/N) SY991A hinge pins
installed. This proposal was published in the Federal Register as a
notice of proposed rulemaking (NPRM) on December 13, 2004 (69 FR
72136). The NPRM proposed to require you to replace any installed
elevator or aileron hinge pins that are not P/N SY991A hinge pins with
P/N SY991A pins.
Comments
Was the public invited to comment? We provided the public the
opportunity to participate in developing this AD. We received no
comments on the proposal or on the determination of the cost to the
public.
Conclusion
What is FAA's final determination on this issue? We have carefully
reviewed the available data and determined that air safety and the
public interest require adopting the AD as proposed except for minor
editorial corrections. We have determined that these minor corrections:
--Are consistent with the intent that was proposed in the NPRM for
correcting the unsafe condition; and
--Do not add any additional burden upon the public than was already
proposed in the NPRM.
Changes to 14 CFR Part 39--Effect on the AD
How does the revision to 14 CFR part 39 affect this AD? On July 10,
2002, the FAA published a new version of 14 CFR part 39 (67 FR 47997,
July 22, 2002), which governs the 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 gliders does this AD impact? We estimate that this AD
affects 57 gliders in the U.S. registry.
What is the cost impact of this AD on owners/operators of the
affected gliders? We estimate the following costs to do the elevator
and aileron hinge pin replacement. We have no way of determining the
number of gliders that may need this hinge pin replacement. However, we
have presented the costs to reflect all 57 gliders needing the
mandatory replacement:
----------------------------------------------------------------------------------------------------------------
Total cost per
Labor cost Parts cost glider Total cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
4 workhours x $65 per hour = $260... $1 $261 $261 x 57 = $14,877
----------------------------------------------------------------------------------------------------------------
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
Will this AD impact various entities? We have 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.
Will this AD involve a significant rule or regulatory action? For
the reasons discussed above, I certify that 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); 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 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 ``Docket
No. FAA-2004-19616; Directorate Identifier 2004-CE-38-AD'' in your
request.
