SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on August 9, 2010 (75 FR 47734). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: Some cases of corrosion were detected in the interface between the elevator hinges fittings (metallic) and the horizontal stabilizer (carbon fibre); investigation identified the cause in galvanic corrosion between dissimilar materials. If left uncorrected, this situation could lead to a structural failure of the elevator, which could result in possible loss of control of the aeroplane. This AD requires: (1) Inspection of the hinges fittings for corrosion and of the stabilizer for delamination; (2) Repair of the stabilizer, if necessary; (3) Replacement of the fittings, if corroded; (4) Improvement of fittings installation; (5) Installation of aluminum strips in the stabilizer to improve bonding, in accordance with Piaggio Aero Industries (PAI) Service Bulletin (SB) 80–0262 Revision 2. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public. Conclusion We reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed. 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 required different actions in this AD from those in the PO 00000 Frm 00004 Fmt 4700 Sfmt 4700 MCAI in order to follow FAA policies. Any such differences are highlighted in a NOTE within the AD. Costs of Compliance We estimate that this proposed AD will affect 96 products of U.S. registry. We also estimate that it would take about 9 work-hours 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 $73,440, or $765 per product. In addition, we estimate that any necessary follow-on actions would take about 32 work-hours and require parts costing $11,000, for a cost of $13,720 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 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 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 E:\FR\FM\05NOR1.SGM 05NOR1 Federal Register / Vol. 75, No. 214 / Friday, November 5, 2010 / Rules and Regulations under the criteria of the Regulatory Flexibility Act. We prepared a regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD Docket. Examining the AD Docket You may examine the AD docket on the Internet at https:// www.regulations.gov; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains the NPRM, the regulatory evaluation, any comments received, and other information.

SUPPLEMENTARY INFORMATION: Discussion Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2010–30R1, dated September 21, 2010 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: Several reports have been received of cracked nacelle attachment fittings. The preliminary investigation determined the cause to be stress corrosion. Stress corrosion cracking could compromise the structural integrity of the nacelle attachment fitting and could adversely affect the safe landing of the aeroplane. This [Canadian] directive, as an interim, mandates a detailed visual inspection [for cracking] and conductivity check of each of the four (4) nacelle attachment fittings. Revision 1 of this [Canadian] directive is issued to update the aircraft serial number (S/N) applicability based on the latest crack findings and also to revise the acceptable conductivity values in Part I.A. In addition, Part II. has been added to provide instructions for newly affected aircraft and aircraft that have replaced nacelle attachment fittings. Failure of the fitting could result in collapse of the landing gear. Required actions include repetitive detailed inspections and replacement of the fittings, depending on inspection PO 00000 Frm 00006 Fmt 4700 Sfmt 4700 findings. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Bombardier has issued Service Bulletin 84–54–14, Revision J, dated September 17, 2010. For certain airplanes, this service bulletin describes procedures for a conductivity inspection and a repetitive detailed inspection for cracking of the nacelle attachment fittings. If the inspections find cracking, this service bulletin specifies replacement of the fitting, or if the inspection finds certain conductivity results, a daily repetitive detailed inspection until replacement of the fitting is accomplished. For certain other airplanes, this service bulletin describes repetitive detailed inspections for cracking of the nacelle attachment fittings and replacement of the fitting if any cracking is found. For all airplanes, this service bulletin specifies that replacement of the fitting extends the compliance time for the first repetitive detailed inspection on that fitting. 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 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 and service information referenced above. We are issuing this AD because we evaluated all pertinent information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. Differences Between the 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 required 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 AD.

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above. 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:

    Some cases of corrosion were detected in the interface between 
the elevator hinges fittings (metallic) and the horizontal 
stabilizer (carbon fibre); investigation identified the cause in 
galvanic corrosion between dissimilar materials.
    If left uncorrected, this situation could lead to a structural 
failure of the elevator, which could result in possible loss of 
control of the aeroplane.

We are issuing this AD to require actions to correct the unsafe 
condition on these products.

DATES: This AD becomes effective December 10, 2010.
    On December 10, 2010, the Director of the Federal Register approved 
the incorporation by reference of certain publications listed in this 
AD.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM was published in the Federal Register on August 9, 2010 (75 
FR 47734). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    Some cases of corrosion were detected in the interface between 
the elevator hinges fittings (metallic) and the horizontal 
stabilizer (carbon fibre); investigation identified the cause in 
galvanic corrosion between dissimilar materials.
    If left uncorrected, this situation could lead to a structural 
failure of the elevator, which could result in possible loss of 
control of the aeroplane.
    This AD requires:
    (1) Inspection of the hinges fittings for corrosion and of the 
stabilizer for delamination;
    (2) Repair of the stabilizer, if necessary;
    (3) Replacement of the fittings, if corroded;
    (4) Improvement of fittings installation;
    (5) Installation of aluminum strips in the stabilizer to improve 
bonding, in accordance with Piaggio Aero Industries (PAI) Service 
Bulletin (SB) 80-0262 Revision 2.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting the AD as proposed.

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 required 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 AD.

Costs of Compliance

    We estimate that this proposed AD will affect 96 products of U.S. 
registry. We also estimate that it would take about 9 work-hours 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 $73,440, or $765 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 32 work-hours and require parts costing $11,000, for a cost 
of $13,720 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 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 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

[[Page 68173]]

under the criteria of the Regulatory Flexibility Act.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD Docket.

Examining the AD Docket

    You may examine the AD docket on the Internet at https://www.regulations.gov; or in person at the Docket Management Facility 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The AD docket contains the NPRM, the regulatory evaluation, 
any comments received, and other information. The street address for

    (a) This airworthiness directive (AD) becomes effective December 
10, 2010.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Model PIAGGIO P-180 airplanes, serial 
numbers 1002 and 1004 through 1191, certificated in any category.

Subject

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

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    Some cases of corrosion were detected in the interface between 
the elevator hinges fittings (metallic) and the horizontal 
stabilizer (carbon fibre); investigation identified the cause in 
galvanic corrosion between dissimilar materials.
    If left uncorrected, this situation could lead to a structural 
failure of the elevator, which could result in possible loss of 
control of the aeroplane.
    This AD requires:
    (1) Inspection of the hinges fittings for corrosion and of the 
stabilizer for delamination;
    (2) Repair of the stabilizer, if necessary;
    (3) Replacement of the fittings, if corroded;
    (4) Improvement of fittings installation;
    (5) Installation of aluminum strips in the stabilizer to improve 
bonding, in accordance with Piaggio Aero Industries (PAI) Service 
Bulletin (SB) 80-0262 Revision 2.

    (f) Unless already done, do the following actions:
    (1) Within the next 1,500 hours time-in-service (TIS) after 
December 10, 2010 (the effective date of this AD) or within 4 years 
after December 10, 2010 (the effective date of this AD), whichever 
occurs first, do the following:
    (i) Remove the left-hand (LH) and the right-hand (RH) elevators 
and do all of the inspections and corrective actions following the 
Accomplishment Instructions in Parts A, B, C, D, and E of PIAGGIO 
AERO INDUSTRIES S.p.A. Service Bulletin (MANDATORY) N.: SB-80-0262, 
Revision 2, dated March 17, 2010.

following the Accomplishment Instructions, Part F, of PIAGGIO AERO 
INDUSTRIES S.p.A. Service Bulletin (MANDATORY) N.: SB-80-0262 
Revision 2, dated March 17, 2010.
    (2) We will allow ``unless already done'' credit for inspections 
and corrective actions already done, before the effective date of 
this AD, following PIAGGIO AERO INDUSTRIES S.p.A. Service Bulletins 
(MANDATORY) N.: SB-80-0262, original issue dated September 24, 2009;
