Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for Piaggio Aero Industries S.p.A. Model P–180 airplanes. 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: pmangrum on DSK3VPTVN1PROD with RULES SUMMARY: Some lock sleeves (part number (P/N) 114146681), which were installed in some Main Landing Gear (MLG) actuators, had been incorrectly manufactured. If left uncorrected, this condition could lead to failure to lock the MLG actuator or to its unlock from the correct position, with subsequent possible damage to the aeroplane and injuries to occupants during landing. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD is effective December 22, 2011. The Director of the Federal Register approved the incorporation by reference VerDate Mar<15>2010 14:30 Nov 16, 2011 Jkt 226001 of a certain publication listed in the AD as of December 22, 2011.

SUPPLEMENTARY INFORMATION: 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 September 1, 2011 (76 FR 54403). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: Some lock sleeves (part number (P/N) 114146681), which were installed in some Main Landing Gear (MLG) actuators, had been incorrectly manufactured. If left uncorrected, this condition could lead to failure to lock the MLG actuator or to its unlock from the correct position, with subsequent possible damage to the aeroplane and injuries to occupants during landing. This AD requires replacing defective MLG actuators with serviceable ones. Defective actuators can be repaired by the manufacturer and identified with the ‘‘P180– 32–29’’ marking on the name plate. Comments We gave the public the opportunity to participate in developing this AD. We considered the comments received. Comment Issue: MLG Actuator Compliance Time Carlo Cardu, Piaggio Aero Industries, stated the MLG actuator has a life-limit based on landings and most operators note the landings accrued on the actuator. Mr. Cardu reasoned that for PO 00000 Frm 00006 Fmt 4700 Sfmt 4700 operators with a higher hours time-inservice (TIS)/landing ratio (more than 1), the AD compliance limit presented in hours TIS would be more stringent than required. As for operators with a lower hours TIS/landing ratio, the AD compliance limit presented in hours TIS would be relaxed with reference to the compliance time of the service information. Mr. Cardu recommended changing the actuator replacement compliances times to read: before affected MLG actuators reach 3000 landings, replace * * *; only if landings data are not available, replace the affected actuator before 3000 FH TIS * * * or similar statement The FAA agrees with the commenter and we changed paragraph (f)(3) of the AD. Conclusion We reviewed the available data, including the comments received, and determined that air safety and the public interest require adopting the AD with the changes described previously. We determined that these changes will not increase the economic burden on any operator or increase the scope of the AD. 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 AD will affect 102 products of U.S. registry. We also estimate that it will take about 0.5 workhour per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts will cost about $0 per product. Based on these figures, we estimate the cost of the AD on U.S. operators to be $4,335, or $43 per product. In addition, we estimate that any necessary follow-on actions will take about 7 work-hours and require parts costing $64,822, for a cost of $65,417 per product. There are a maximum of 17 actuators that are identified by the E:\FR\FM\17NOR1.SGM 17NOR1 Federal Register / Vol. 76, No. 222 / Thursday, November 17, 2011 / Rules and Regulations manufacturer that will be required to be replaced. We have no way of determining the number of affected airplanes on the U.S. registry that may have these actuators that may have to be replaced by these actions. According to the manufacturer, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. There is a warranty expiration date for the replacement of the actuators. The FAA recommends owners/operators that have affected main landing gear actuators contact the manufacturer immediately and replace the actuators under warranty. pmangrum on DSK3VPTVN1PROD with RULES 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 under the criteria of the Regulatory Flexibility Act. VerDate Mar<15>2010 14:30 Nov 16, 2011 Jkt 226001 71247 We prepared a regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD Docket. (d) Subject Air Transport Association of America (ATA) Code 32: Landing Gear. Examining the AD Docket (e) Reason The mandatory continuing airworthiness information (MCAI) states: Some lock sleeves (part number (P/N) 114146681), which were installed in some Main Landing Gear (MLG) actuators, had been incorrectly manufactured. If left uncorrected, this condition could lead to failure to lock the MLG actuator or to its unlock from the correct position, with subsequent possible damage to the aeroplane and injuries to occupants during landing. This AD requires replacing defective MLG actuators with serviceable ones. Defective actuators can be repaired by the manufacturer and identified with the ‘‘P180– 32–29’’ marking on the name plate.

Airworthiness Directives; Piaggio Aero Industries S.p.A. 
Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for Piaggio 
Aero Industries S.p.A. Model P-180 airplanes. 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 lock sleeves (part number (P/N) 114146681), which were 
installed in some Main Landing Gear (MLG) actuators, had been 
incorrectly manufactured.
    If left uncorrected, this condition could lead to failure to 
lock the MLG actuator or to its unlock from the correct position, 
with subsequent possible damage to the aeroplane and injuries to 
occupants during landing.

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

DATES: This AD is effective December 22, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of December 22, 
2011.

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 September 1, 2011 
(76 FR 54403). That NPRM proposed to correct an unsafe condition for 
the specified products. The MCAI states:

    Some lock sleeves (part number (P/N) 114146681), which were 
installed in some Main Landing Gear (MLG) actuators, had been 
incorrectly manufactured.
    If left uncorrected, this condition could lead to failure to 
lock the MLG actuator or to its unlock from the correct position, 
with subsequent possible damage to the aeroplane and injuries to 
occupants during landing.
    This AD requires replacing defective MLG actuators with 
serviceable ones.
    Defective actuators can be repaired by the manufacturer and 
identified with the ``P180-32-29'' marking on the name plate.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the comments received.

Comment Issue: MLG Actuator Compliance Time

    Carlo Cardu, Piaggio Aero Industries, stated the MLG actuator has a 
life-limit based on landings and most operators note the landings 
accrued on the actuator. Mr. Cardu reasoned that for operators with a 
higher hours time-in-service (TIS)/landing ratio (more than 1), the AD 
compliance limit presented in hours TIS would be more stringent than 
required. As for operators with a lower hours TIS/landing ratio, the AD 
compliance limit presented in hours TIS would be relaxed with reference 
to the compliance time of the service information. Mr. Cardu 
recommended changing the actuator replacement compliances times to 
read:

before affected MLG actuators reach 3000 landings, replace * * *; 
only if landings data are not available, replace the affected 
actuator before 3000 FH TIS * * * or similar statement

    The FAA agrees with the commenter and we changed paragraph (f)(3) 
of the AD.

Conclusion

    We reviewed the available data, including the comments received, 
and determined that air safety and the public interest require adopting 
the AD with the changes described previously. We determined that these 
changes will not increase the economic burden on any operator or 
increase the scope of the AD.

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 AD will affect 102 products of U.S. registry. 
We also estimate that it will take about 0.5 work-hour per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour. Required parts will cost about $0 per product.
    Based on these figures, we estimate the cost of the AD on U.S. 
operators to be $4,335, or $43 per product.
    In addition, we estimate that any necessary follow-on actions will 
take about 7 work-hours and require parts costing $64,822, for a cost 
of $65,417 per product. There are a maximum of 17 actuators that are 
identified by the

[[Page 71247]]

manufacturer that will be required to be replaced. We have no way of 
determining the number of affected airplanes on the U.S. registry that 
may have these actuators that may have to be replaced by these actions.
    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.
    There is a warranty expiration date for the replacement of the 
actuators. The FAA recommends owners/operators that have affected main 
landing gear actuators contact the manufacturer immediately and replace 
the actuators under warranty.

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 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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
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]

0
2. The FAA amends Sec.  39.13 by adding the following new AD:

2011-24-01 Piaggio Aero Industries S.p.A.: Amendment 39-16865; 
Docket No. FAA-2011-0954; Directorate Identifier 2011-CE-028-AD.

(a) Effective Date

    This airworthiness directive (AD) becomes effective December 22, 
2011.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to PIAGGIO AERO INDUSTRIES S.p.A Model PIAGGIO 
P-180 airplanes, all serial numbers, that are:
    (1) Certificated in any category; and
    (2) Have any of the following main landing gear (MLG) actuators 
installed:
    (i) Messier-Dowty Part Number (P/N) 114346003 (left hand side): 
with serial number (S/N) SA0706275, SA0706276, SA0706726, SA0706727, 
SA0706728, SA0706729, SA0706738, SA0706739,SA0707243, SA0707864, or 
SA0708072; or
    (ii) Messier-Dowty P/N 114346004 (right hand side): with S/N 
SA0703800, SA0703801, SA0705520, SA0706219, SA0706960, or SA0706961.

(d) Subject

    Air Transport Association of America (ATA) Code 32: Landing 
Gear.

(e) Reason

    The mandatory continuing airworthiness information (MCAI) 
states:
    Some lock sleeves (part number (P/N) 114146681), which were 
installed in some Main Landing Gear (MLG) actuators, had been 
incorrectly manufactured.
    If left uncorrected, this condition could lead to failure to 
lock the MLG actuator or to its unlock from the correct position, 
with subsequent possible damage to the aeroplane and injuries to 
occupants during landing.
    This AD requires replacing defective MLG actuators with 
serviceable ones.
    Defective actuators can be repaired by the manufacturer and 
identified with the ``P180-32-29'' marking on the name plate.

(f) Actions and Compliance

    Unless already done, do the following actions:
    (1) Within 25 hours time-in-service (TIS) after December 22, 
2011 (the effective date of this AD), inspect both installed MLG 
actuators to determine if an affected P/N and S/N actuator is 
installed.
    (2) If any affected P/N and S/N actuator is identified with the 
``P180-32-29'' marking on the name plate, no further action is 
required by this AD on that actuator.
    (3) If one or both affected MLG actuators are not identified 
with the ``P180-32-29'' marking on the name plate, before reaching a 
total of 3,000 landings on the actuator or within the next 150 
landings after December 22, 2011 (the effective date of this AD), 
whichever occurs later, replace the affected actuator(s) with 
serviceable parts following Part B of the Accomplishments 
Instructions of Piaggio Aero Industries S.p.A. Mandatory Service 
Bulletin No. 80-0304, dated July 9, 2010. If landing data is not 
available, the use of a one-to-one landing to flight hour conversion 
must be applied (example: 3,000 landings equal 3,000 hours TIS).
    (4) After December 22, 2011 (the effective date of this AD), do 
not install any MLG actuator having an affected P/N and S/N, unless 
it is identified with the ``P180-32-29'' marking on the name plate.

    Note 1: There is a warranty expiration date for the replacement 
of the actuators. The FAA recommends owners/operators that have 
affected main landing gear actuators contact the manufacturer 
immediately and replace the actuators under warranty.

FAA AD Differences

    Note 2: This AD differs from the MCAI and/or service information 
as follows: None.

(g) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
Standards Office, FAA, has the authority to approve AMOCs for this 
AD, if requested using the procedures found in 14 CFR 39.19. Send 
information to ATTN: Mike Kiesov, Aerospace Engineer, FAA, Small

approved AMOC on any airplane to which the AMOC applies, notify your 
appropriate principal inspector (PI) in the FAA Flight Standards 
District Office (FSDO), or lacking a PI, your local FSDO.
    (2) Airworthy Product: For any requirement in this AD to obtain 
corrective actions from a manufacturer or other source, use these 
actions if they are FAA-approved. Corrective actions are considered 
FAA-approved if they are approved by the State of Design Authority 
(or their delegated agent). You are required to assure the product 
is airworthy before it is returned to service.
    (3) Reporting Requirements: For any reporting requirement in 
this AD, a federal agency may not conduct or sponsor, and a person 
is not required to respond to, nor shall a person be subject to a 
penalty for failure to comply with a collection of information 
subject to the requirements of the Paperwork Reduction Act unless 
that collection of information displays a current valid OMB Control 
Number. The OMB Control Number for this information collection is 
2120-0056. Public reporting for this collection of information is 
estimated to be approximately 5 minutes per response, including the 
time for reviewing instructions, completing and reviewing the 
collection of information. All responses to this collection of 
information are mandatory. Comments concerning the accuracy of this 
burden and suggestions for reducing the burden should be directed to
