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. This AD requires you to make pen and ink changes to the Limitations Section of the glider maintenance manual to eliminate contradictory information concerning the structural life limit. This AD results from a review by FAA of the Limitations Section of the CENTRAIR Model 101AP glider maintenance manual that revealed conflicting information concerning the structural life limit. We are issuing this AD to assure that the published life limit is adhered to and to prevent structural failure of the glider once this life limit is reached.
DATES: This AD becomes effective on January 3, 2006.
ADDRESSES: To get the service information identified in this AD, contact CENTRAIR, Aerodome B.P.N. 44, 36300 Le Blanc, France; telephone: 02.54.37.07.96; facsimile: 02.54.37.48.64.

Identifier 2005-CE-39-AD.

SUPPLEMENTARY INFORMATION:
Discussion
What events have caused this AD? A review by FAA of the Limitations Section of the CENTRAIR Model 101AP glider maintenance manual revealed conflicting information concerning the structural life limit. Page 5.1 of this manual specifies inspection criteria upon accumulating 3,000 hour time-in-service (TIS). However, page 5.01 of the manual identifies a structural life limit of 3,000-hour TIS. CENTRAIR has verified that all the 101 series gliders delivered to the United States have a 3,000- hour life limit with no current extension.
Cumulative fatigue damage and fatigue cracking damage would sufficiently reduce residual strength of the airframe and result in failure of the airframe.
What is the potential impact if FAA took no action? If this situation is not corrected, the published life limit may not be adhered to and the structural integrity of the glider could be compromised.
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. This proposal was published in the Federal Register as a notice of proposed rulemaking (NPRM) on August 22, 2005 (70 FR 48918). The NPRM proposed to require you to make pen and ink changes to the Limitations Section of the glider maintenance manual to eliminate contradictory information concerning the structural life limit.
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 51 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 this change of the maintenance manual:
Total cost per Total cost on Labor cost
Parts cost
glider U.S. operators
1 work hour x $65 = $65.................... Not Applicable.....................
$65
$3,315

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:
-
Is not a ``significant regulatory action'' under Executive Order 12866;
-
Is not a ``significant rule'' under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and
-
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-2005-21951; Directorate Identifier 2005-CE-39-AD'' in your request.
