### AD Notice of Proposed Rulemaking

Feder al Register Information [Federal Register: April 2, 2010 (Volume 75, Number 63)] [Page 16685 - 16689] Header Information DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA - 2010 - 0281; Directorate Identifier 2009 - NM - 184 - AD] RIN 2120 - AA64 Airwor thiness Directives; Airbus Model A300 - 600 and A310 Airplanes Pream ble Information AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM).

----------------------------------------------------------------------- SUMMARY: We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsa fe condition on an aviation product. The MCAI describes the unsafe condition as: Surface defects were visually detected on the rudder of one Airbus A319 and one A321 in - service aeroplane. Investigation has determined that the defects reported on both rudde rs corresponded to areas that had been reworked in production. The investigation confirmed that the defects were the result of de - bonding between the skin and honeycomb core. Such reworks were also performed on some rudders fitted on A310 and A300 - 600 aero planes. An extended de - bonding, if not detected and corrected, may degrade the structural integrity of the rudder. The loss of the rudder leads to degradation of the handling qualities and reduces the controllability of the aeroplane. The proposed AD wou ld require actions that are intended to address the unsafe condition described in the MCAI. DATES: We must receive comments on this proposed AD by May 17, 2010. ADDRESSES: You may send comments by any of the following methods: Federal eRulemaking Portal: Go to http:// www.regulations.gov. Follow the instructions for submitting comments.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member St ates of the European Community, has issued EASA Airworthiness Directive 2010 - 0002, dated January 5, 2010 (referred to after this as "the MCAI''), to correct an unsafe condition for the specified products. The MCAI states: Surface defects were visually de tected on the rudder of one Airbus A319 and one A321 in service aeroplane. Investigation has determined that the defects reported on both rudders corresponded to areas that had been reworked in production. The investigation confirmed that the defects were the result of de - bonding between the skin and honeycomb core. Such reworks were also performed on some rudders fitted on A310 and A300 - 600 aeroplanes. An extended de - bonding, if not detected and corrected, may degrade the structural integrity of the rudd er. The loss of the rudder leads to degradation of the handling qualities and reduces the controllability of the aeroplane. To address this unsafe condition [this EASA AD] requires inspections of specific areas and, depending on findings, the application of corrective actions for those rudders where production reworks have been identified. This * * * [EASA] AD * * * also requires for the vacuum loss hole restoration:

-- A local ultrasonic inspection for reinforced area instead of the local thermographi c inspection, which is maintained for non - reinforced areas, and -- Additional work performance for rudders on which this thermographic inspection has been performed in the reinforced area. The inspections include vacuum loss inspections and elasticity la minate checker inspections for defects including de - bonding between the skin and honeycomb core of the rudder, and ultrasonic inspections for rudders on which temporary restoration with resin or permanent vacuum loss hole restoration has been performed. Th e corrective action is contacting the manufacturer for repair instructions and doing the repair. We are considering similar rulemaking action on Models A319 and A321 airplanes. You may obtain further information by examining the MCAI in the AD docket. Re levant Service Information Airbus has issued All Operators Telex (AOT) A300 - 55A6047, Revision 02, dated October 12, 2009; and AOT A310 - 55A2048, Revision 02, dated October 12, 2009. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. FAA's Determination and Requirements of This 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 bila teral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and serviceinformation referenced above. We are proposing this AD because we evaluated all pertinent

information and determined an unsa fe condition exists and is likely to exist or develop on other products of the same type design. Differences Between This 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 B ased on the service information, we estimate that this proposed AD would affect about 194 products of U.S. registry. We also estimate that it would take about 4 work - hours per product to comply with the basic requirements of this proposed AD. The average l abor rate is $85 per work hour. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $65,960, or $340 per product. Authority for This Rulemaking Title 49 of the United States Code specifies the FAA's authority to issu e 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 de scribed 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 procedure s 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 State s, 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 Regulato ry Flexibility Act. We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by referenc e, Safety. 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: Regulatory Information Airbus: Docket No. FAA - 2010 - 0281; Directorate Identifier 2009 - NM - 184 - AD. Comments Due Date (a) We must receive comments by May 17, 2010. Affected ADs (b) None.

Reason (e) The mandatory continuing airworthiness information (MCAI) states: Surface defects were visually detected on the rudder of one Airbus A319 and one A321 in service aeroplane. Investigation has determined that the defects reported on both rudders corresponded to areas that had been reworked in production. The investigation confirmed that the defects were the result of de - bonding between the skin and honeycomb core. Such reworks were also performed on some rudders fitted on A310 and A300 - 600 aeroplanes. An extended de - bonding, if not detected and corrected, may degrade the structural integrity of the rudder. The loss o f the rudder leads to degradation of the handling qualities and reduces the controllability of the aeroplane. To address this unsafe condition [this EASA AD] requires inspections of specific areas and, depending on findings, the application of corrective actions for those rudders where productionreworks have been identified.

This * * * [EASA] AD * * * also requires for the vacuum loss hole restoration:

-- A local ultrasonic inspection for reinforced area instead of the local thermographic inspection, which is maintained for non - reinforced areas, and -- Additional work performance for rudders on which this thermographic inspection has been performed in the reinforced area. The inspections include vacuum loss inspections and elasticity laminate checker i nspections for defects including de - bonding between the skin and honeycomb core of the rudder, and ultrasonic inspections for rudders on which temporary restoration with resin or permanent vacuum loss hole restoration has been performed. The corrective act ion is contacting the manufacturer for repair instructions and doing the repair. We are considering similar rulemaking action on Models A319 and A321 airplanes. Compliance (f) You are responsible for having the actions required by this AD performed wit hin the compliance times specified, unless the actions have already been done.
