Ali Bahrami, Manager, Transport Airplane Directorate, Aircraft Certification Service. Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A300 B4–600, B4–600R, and F4–600R series airplanes, and Model A300 C4–605R Variant F airplanes (collectively called A300–600 series airplanes); and Model A310 series airplanes. This proposed AD was prompted by reports of cracking through the honeycomb core closed with phenolic resin. This condition could result in extended debonding and could adversely affect the structural integrity of the rudder. This proposed AD would require inspecting to determine the serial number of a certain rudder and replacing the rudder with a new or serviceable rudder if necessary.

We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2012–0006, dated January 12, 2012 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: Following in-service findings reported by an operator, rudder laboratory investigation revealed the existence of a crack through the honeycomb core closed with phenolic resin. This condition if not detected and corrected, could result in extended de-bonding, which would adversely affect the structural integrity of the rudder. The loss of the rudder could lead to degradation of the handling qualities and reduces the controllability of the aeroplane. Further investigations identified a batch of five affected rudders. For the reasons described above, this [EASA] AD requires [inspecting to determine the serial number (S/N) of a certain rudder and] the replacement of the five affected rudders with [new or] serviceable ones. You may obtain further information by examining the MCAI in the AD docket. 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 bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design. wreier-aviles on DSK5TPTVN1PROD with PROPOSALS Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 170 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 proposed AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $14,450, or $85 per product. In addition, we estimate that any necessary follow-on actions would take about 10 work-hours and require parts costing $714,100, for a cost of $714,950 per product. We have no way of VerDate Mar<15>2010 15:05 Sep 25, 2012 Jkt 226001 determining the number of products that may need these actions. PART 39—AIRWORTHINESS DIRECTIVES Authority for This Rulemaking 1. The authority citation for part 39 continues to read as follows: 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 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 States, 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); 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. 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 reference, 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: PO 00000 Frm 00014 Fmt 4702 Sfmt 4702 Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2.

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Airbus Model A300 B4-600, B4-600R, and F4-600R series 
airplanes, and Model A300 C4-605R Variant F airplanes (collectively 
called A300-600 series airplanes); and Model A310 series airplanes. 
This proposed AD was prompted by reports of cracking through the 
honeycomb core closed with phenolic resin. This condition could result 
in extended debonding and could adversely affect the structural 
integrity of the rudder. This proposed AD would require inspecting to 
determine the serial number of a certain rudder and replacing the 
rudder with a new or serviceable rudder if necessary. We are proposing 
this AD to prevent extended de-bonding, which could result in loss of 
the rudder and consequent reduced controllability of the airplane.

DATES: We must receive comments on this proposed AD by November 13, 
2012.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2012-0006, dated January 12, 2012 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    Following in-service findings reported by an operator, rudder 
laboratory investigation revealed the existence of a crack through 
the honeycomb core closed with phenolic resin. This condition if not 
detected and corrected, could result in extended de-bonding, which 
would adversely affect the structural integrity of the rudder. The 
loss of the rudder could lead to degradation of the handling 
qualities and reduces the controllability of the aeroplane.
    Further investigations identified a batch of five affected 
rudders.
    For the reasons described above, this [EASA] AD requires 
[inspecting to determine the serial number (S/N) of a certain rudder 
and] the replacement of the five affected rudders with [new or] 
serviceable ones.

You may obtain further information by examining the MCAI in the AD 
docket.

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 bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI referenced 
above. We are proposing this AD because we evaluated all pertinent 
information and determined an unsafe condition exists and is likely to 
exist or develop on other products of the same type design.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 170 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 proposed AD. The average labor rate is $85 per 
work-hour. Based on these figures, we estimate the cost of the proposed 
AD on U.S. operators to be $14,450, or $85 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 10 work-hours and require parts costing $714,100, for a cost 
of $714,950 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 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 States, 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);
    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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket.

622, B4-605R, B4-622R, F4-605R, F4-622R, and C4-605R Variant F 
airplanes; and Model A310-203, -204, -221, -222, -304, -322, -324, 
and -325 airplanes; certificated in any category; all serial 
numbers, except those airplanes on which Airbus modification 08827 
has been incorporated in production.

(d) Subject

    Air Transport Association (ATA) of America Code 55, Stabilizers.

(e) Reason

    This AD was prompted by reports of cracking through the 
honeycomb core closed with phenolic resin. This condition could 
result in extended debonding and could adversely affect the 
structural integrity of the rudder. We are issuing this AD to 
prevent extended de-bonding, which could result in loss of the 
rudder and consequent reduced controllability of the airplane.

(f) Compliance

    You are responsible for having the actions required by this AD 
performed within the compliance times specified, unless the actions 
have already been done.

(g) Inspection

    Within 3 months after the effective date of this AD, inspect the 
rudder having part number (P/N) A55471500, to determine if the 
rudder has serial number (S/N) HF1010, HF1036, HF1059, HF1061, or 
HF1064. A review of airplane maintenance records is acceptable in 
lieu of this inspection if the serial number of the rudder can be 
conclusively determined from that review.

(h) Rudder Replacement

    If, during the inspection required by paragraph (g) of this AD, 
any rudder having S/N HF1010, HF1036, HF1059, HF1061, or HF1064 is 
found, before further flight, replace the rudder with a new or 
serviceable rudder, using a method approved by either the Manager, 
International Branch, ANM-116, Transport Airplane Directorate, FAA; 
or the European Aviation Safety Agency (EASA) (or its delegated 
agent).
    Note 1 to Paragraph (h) of this AD: Rudders having S/N HF1010, 
HF1036, HF1059,

[[Page 59151]]

HF1061, and HF1064 were installed on airplanes having S/N 0295, 
0297, 0321, 0355, and 0500; however, each rudder may have been moved 
to another airplane.

(i) Parts Installation Prohibition

    As of the effective date of this AD, no person may install a 
rudder P/N A55471500, having S/N HF1010, HF1036, HF1059, HF1061, or 
HF1064, on any airplane.

(j) Other FAA AD Provisions
