SUPPLEMENTARY INFORMATION:
BILLING CODE 4910–13–P
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 July 16, 2007 (72 FR 38800).
That NPRM proposed to correct an
unsafe condition for the specified
products. The MCAI states:

ACTION: Final rule.
AGENCY:
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:
Several aircraft, at the factory, presented
some debris in the hydraulic fluid of the
steering system. Investigations revealed that
some components of the steering system can
be responsible for the fluid contamination
because of an initial pollution on their
manufacturing.
If not corrected, a contaminated fluid could
cause malfunction and a possible jamming of
the steering system.
We are issuing this AD to require
actions to correct the unsafe condition
on these products.
DATES: This AD becomes effective
October 11, 2007.
On October 11, 2007, the Director of
the Federal Register approved the
incorporation by reference of certain
publications listed in this AD.

Discussion
Several aircraft, at the factory, presented
some debris in the hydraulic fluid of the
steering system. Investigations revealed that
some components of the steering system can
be responsible for the fluid contamination
because of an initial pollution on their
manufacturing.
If not corrected, a contaminated fluid could
cause malfunction and a possible jamming of
the steering system.
The superseded Airworthiness Directive
(AD) 2007–0088–E was previously issued to
address the unsafe condition.
The present Airworthiness Directive
expands applicability of this AD to all P.180
‘Avanti’ series aircraft and the list of
defective components as listed in revision 1
of Piaggio Aero Industries Mandatory Service
Bulletin No 80–0236. This AD also requires
Temporary Changes to the respective
Airplane Flight Manual (AFM) and Aircraft
Maintenance Manual (AMM) and introduces
procedures to recondition defective units.
Comments
We gave the public the opportunity to
participate in developing this AD. We
considered the comment received.
Comment Issue: Replacement of Nose
Landing Gear
One commenter suggests that the nose
landing gear (NLG) does not need to be
replaced as required in paragraph
(f)(2)(ii) of this AD, but rather the
steering actuator and manifold mounted
to the NLG need to be replaced.
We agree with the commenter that it
is the steering actuator and the manifold
that need to be replaced and not the
entire NLG. However, the service
bulletin requires removing and sending
the original NLG to a Messier-Dowty
engineer to do the actuator and
manifold replacement. The service
bulletin then requires installing a
serviceable NLG. The replacement NLG
could be the original, which has been
rebuilt according to Annex 8 of Piaggio
Aero Industries S.p.A. Service Bulletin
(Mandatory) N.: 80–0236 Rev. 1, dated
May 15, 2007 (Messier-Dowty Service
Bulletin No. P180–32–24, dated May 15,
2007), or it could be an exchanged NLG
that complies with this AD. We have
E:\FR\FM\06SER1.SGM
06SER1
51168
Federal Register / Vol. 72, No. 172 / Thursday, September 6, 2007 / Rules and Regulations
added a note to clarify that the NLG can
be the same one that was removed if it
has been serviced to comply with this
AD.
Conclusion
We reviewed the available data,
including the comment 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
Regulatory Findings
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
63 products of U.S. registry. We also
estimate that it will take about 1 workhour per product to comply with basic
requirements of this AD. The average
labor rate is $80 per work-hour.
Based on these figures, we estimate
the cost of this AD to the U.S. operators
to be $5,040, or $80 per product.
In addition, we estimate that any
necessary follow-on actions would take
about 14 work-hours, for a cost of
$1,120 per product. Where the service
information lists required parts costs
that are covered under warranty, we
have assumed that there will be no
charge for these costs. As we do not
control warranty coverage for affected
parties, some parties may incur costs
higher than estimated here. We have no
way of determining the number of
products that may need these actions.
pwalker on PROD1PC71 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.
VerDate Aug<31>2005
18:26 Sep 05, 2007
Jkt 211001
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.
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.
Examining the AD Docket
You may examine the AD docket on
the Internet at https://dms.dot.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 the
Docket Office (telephone (800) 647–
5527) is in the ADDRESSES section.
Comments will be available in the AD
docket shortly after receipt.

Amendment 39–15187; Docket No.
FAA–2007–27975; Directorate Identifier
2007–CE–041–AD.
Effective Date
(a) This airworthiness directive (AD)
becomes effective October 11, 2007.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Model P–180
airplanes, all serial numbers, certificated in
any category.
Subject
(d) Air Transport Association of America
(ATA) Code 32: Landing Gear.
Reason
(e) The mandatory continuing
airworthiness information (MCAI) states:
Several aircraft, at the factory, presented
some debris in the hydraulic fluid of the
steering system. Investigations revealed that
some components of the steering system can
be responsible for the fluid contamination
because of an initial pollution on their
manufacturing.
If not corrected, a contaminated fluid could
cause malfunction and a possible jamming of
the steering system.
The superseded Airworthiness Directive
(AD) 2007–0088–E was previously issued to
address the unsafe condition.
The present Airworthiness Directive
expands applicability of this AD to all P.180
‘Avanti’ series aircraft and the list of
defective components as listed in revision 1
of Piaggio Aero Industries Mandatory Service
Bulletin No 80–0236. This AD also requires
Temporary Changes to the respective
Airplane Flight Manual (AFM) and Aircraft
Maintenance Manual (AMM) and introduces
procedures to recondition defective units.
Actions and Compliance
(f) Unless already done, do the following
actions:
(1) Within the next 30 hours time-inservice (TIS) after October 11, 2007 (the
effective date of this AD) or 30 days after
October 11, 2007 (the effective date of this
AD), whichever occurs first, inspect the
identification of the steering actuator and the
steering manifold installed on the airplane
following Piaggio Aero Industries S.p.A.

effective date of this AD), whichever occurs
first, replace the nose landing gear (NLG)
following Piaggio Aero Industries S.p.A.
Service Bulletin (Mandatory) N.: 80–0236
Rev. 1, dated May 15, 2007.
Note 1: The replacement NLG could be the
same unit that was removed from the aircraft
and serviced in accordance with Annex 8 of
Piaggio Aero Industries S.p.A. Service
Bulletin (Mandatory) N.: 80–0236 Rev. 1,
dated May 15, 2007 (Messier-Dowty Service
Bulletin No. P180–32–24, dated May 15,
2007), or it could be a different NLG that
complies with this AD.
(iii) After replacement of the NLG per
paragraph (f)(2)(ii) of this AD, remove the
steering system temporary limitations from
the LIMITATIONS section of the AFM.
(3) Before further flight after
accomplishment of the inspection specified
in paragraph (f)(1) of this AD, do not install
any steering actuator listed in annex 7.1 or
manifold listed in annex 7.2 of Piaggio Aero
Industries S.p.A. Service Bulletin
(Mandatory) N.: 80–0236 Rev. 1, dated May
15, 2007.
Note 2: We encourage you to incorporate
Temporary Revision 1 into the maintenance
program (aircraft maintenance manual
(AMM) P.180 Avanti report 9066) or
Temporary Revision 11 into the maintenance
program (AMM P.180 Avanti II report 180–
MAN–0200–01105). The temporary revisions
require confirmation that the steering
manifold and steering actuator are compliant
with Piaggio Aero Industries S.p.A. Service
Bulletin (Mandatory) N.: 80–0236 Rev. 1,
dated May 15, 2007.

FAA AD Differences
Note 3: This AD differs from the MCAI
and/or service information as follows: The
MCAI requires the initial inspection action
within 5 hours TIS. We consider 5 hours TIS
an urgent safety of flight compliance time,
and we do not consider this unsafe condition
to be an urgent safety of flight condition.
Because we do not consider this unsafe
condition to be an urgent safety of flight
condition, we issued this action through the
normal notice of proposed rulemaking
(NPRM) AD process followed by this final
rule. The initial compliance time of 30 hours
VerDate Aug<31>2005
18:26 Sep 05, 2007
Jkt 211001
51169
TIS after the effective date of this AD or 30
days after the effective date of this AD,
whichever occurs first, is an adequate
compliance time for this AD action and met
the FAA requirements for an NPRM followed
by a final rule.

Comment Issue: Replacement of Nose Landing Gear
One commenter suggests that the nose landing gear (NLG) does not
need to be replaced as required in paragraph (f)(2)(ii) of this AD, but
rather the steering actuator and manifold mounted to the NLG need to be
replaced.
We agree with the commenter that it is the steering actuator and
the manifold that need to be replaced and not the entire NLG. However,
the service bulletin requires removing and sending the original NLG to
a Messier-Dowty engineer to do the actuator and manifold replacement.
The service bulletin then requires installing a serviceable NLG. The
replacement NLG could be the original, which has been rebuilt according
to Annex 8 of Piaggio Aero Industries S.p.A. Service Bulletin
(Mandatory) N.: 80-0236 Rev. 1, dated May 15, 2007 (Messier-Dowty
Service Bulletin No. P180-32-24, dated May 15, 2007), or it could be an
exchanged NLG that complies with this AD. We have
[[Page 51168]]
added a note to clarify that the NLG can be the same one that was
removed if it has been serviced to comply with this AD.
Conclusion
We reviewed the available data, including the comment 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 63 products of U.S. registry.
We also estimate that it will take about 1 work-hour per product to
comply with basic requirements of this AD. The average labor rate is
$80 per work-hour.
Based on these figures, we estimate the cost of this AD to the U.S.
operators to be $5,040, or $80 per product.
In addition, we estimate that any necessary follow-on actions would
take about 14 work-hours, for a cost of $1,120 per product. Where the
service information lists required parts costs that are covered under
warranty, we have assumed that there will be no charge for these costs.
As we do not control warranty coverage for affected parties, some
parties may incur costs higher than estimated here. 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 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://
dms.dot.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 the Docket
Office (telephone (800) 647-5527) is in the ADDRESSES section. Comments
will be available in the AD docket shortly after receipt.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
Adoption of the Amendment
0
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:
2007-18-07 Piaggio Aero Industries S.p.A.: Amendment 39-15187;
Docket No. FAA-2007-27975; Directorate Identifier 2007-CE-041-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective October
11, 2007.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Model P-180 airplanes, all serial
numbers, certificated in any category.
Subject
(d) Air Transport Association of America (ATA) Code 32: Landing
Gear.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
Several aircraft, at the factory, presented some debris in the
hydraulic fluid of the steering system. Investigations revealed that
some components of the steering system can be responsible for the
fluid contamination because of an initial pollution on their
manufacturing.
If not corrected, a contaminated fluid could cause malfunction
and a possible jamming of the steering system.
The superseded Airworthiness Directive (AD) 2007-0088-E was
previously issued to address the unsafe condition.
The present Airworthiness Directive expands applicability of
this AD to all P.180 `Avanti' series aircraft and the list of
defective components as listed in revision 1 of Piaggio Aero
Industries Mandatory Service Bulletin No 80-0236. This AD also
requires Temporary Changes to the respective Airplane Flight Manual
(AFM) and Aircraft Maintenance Manual (AMM) and introduces
procedures to recondition defective units.
Actions and Compliance
(f) Unless already done, do the following actions:
(1) Within the next 30 hours time-in-service (TIS) after October
11, 2007 (the effective date of this AD) or 30 days after October
11, 2007 (the effective date of this AD), whichever occurs first,
inspect the identification of the steering actuator and the steering
manifold installed on the airplane following Piaggio Aero Industries
S.p.A. Service Bulletin (Mandatory) N.: 80-0236 Rev. 1, dated May
15, 2007.
(2) If any steering actuator listed in annex 7.1 or manifold
listed in annex 7.2 of Piaggio Aero Industries S.p.A. Service
Bulletin (Mandatory) N.: 80-0236 Rev. 1, dated May
[[Page 51169]]
15, 2007, is found in the inspection per paragraph (f)(1) of this
AD:
(i) Before further flight after the inspection per paragraph
(f)(1) of this AD, insert Temporary Change 3, issued March 15, 2007,
into the LIMITATIONS section of Report 6591 (the airplane flight
manual (AFM)) for P-180 Avanti Aircraft or Temporary Change 2,
issued March 15, 2007, into the LIMITATIONS section of Report 180-
MAN-0010-01100 (the AFM) for P-180 Avanti II aircraft. The owner/
operator holding at least a private pilot certificate as authorized
by section 43.7 of the Federal Aviation Regulations (14 CFR 43.7)
may do this action. Make an entry in the aircraft records showing
compliance with this portion of the AD following section 43.9 of the
Federal Aviation Regulations (14 CFR 43.9).
(ii) Within the next 600 hours TIS after October 11, 2007 (the
effective date of this AD) or 12 months after October 11, 2007 (the
effective date of this AD), whichever occurs first, replace the nose
landing gear (NLG) following Piaggio Aero Industries S.p.A. Service
Bulletin (Mandatory) N.: 80-0236 Rev. 1, dated May 15, 2007.
Note 1: The replacement NLG could be the same unit that was
removed from the aircraft and serviced in accordance with Annex 8 of
Piaggio Aero Industries S.p.A. Service Bulletin (Mandatory) N.: 80-
0236 Rev. 1, dated May 15, 2007 (Messier-Dowty Service Bulletin No.
P180-32-24, dated May 15, 2007), or it could be a different NLG that
complies with this AD.
(iii) After replacement of the NLG per paragraph (f)(2)(ii) of
this AD, remove the steering system temporary limitations from the
LIMITATIONS section of the AFM.
(3) Before further flight after accomplishment of the inspection
specified in paragraph (f)(1) of this AD, do not install any
steering actuator listed in annex 7.1 or manifold listed in annex
7.2 of Piaggio Aero Industries S.p.A. Service Bulletin (Mandatory)
N.: 80-0236 Rev. 1, dated May 15, 2007.
Note 2: We encourage you to incorporate Temporary Revision 1
into the maintenance program (aircraft maintenance manual (AMM)
P.180 Avanti report 9066) or Temporary Revision 11 into the
maintenance program (AMM P.180 Avanti II report 180-MAN-0200-01105).
The temporary revisions require confirmation that the steering
manifold and steering actuator are compliant with Piaggio Aero
Industries S.p.A. Service Bulletin (Mandatory) N.: 80-0236 Rev. 1,
dated May 15, 2007.
FAA AD Differences
Note 3: This AD differs from the MCAI and/or service information
as follows: The MCAI requires the initial inspection action within 5
hours TIS. We consider 5 hours TIS an urgent safety of flight
compliance time, and we do not consider this unsafe condition to be
an urgent safety of flight condition. Because we do not consider
this unsafe condition to be an urgent safety of flight condition, we
issued this action through the normal notice of proposed rulemaking
(NPRM) AD process followed by this final rule. The initial
compliance time of 30 hours TIS after the effective date of this AD
or 30 days after the effective date of this AD, whichever occurs
first, is an adequate compliance time for this AD action and met the
FAA requirements for an NPRM followed by a final rule.
Other FAA AD Provisions
(g) 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

Missouri 64106; telephone: (816) 329-4145; fax: (816) 329-4090.
Before using any 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, under the provisions of the Paperwork Reduction Act (44
U.S.C. 3501 et. seq.), the Office of Management and Budget (OMB) has
approved the information collection requirements and has assigned
OMB Control Number 2120 0056.
