111/a, dated September 20, 2005, for related
information.
Note: This AD differs from the MCAI and/
or service information as follows:
(1) The MCAI and service bulletin require
the insertion of Diamond Aircraft Airplane
Flight Manual Temporary Revision
¨
Performance Data DA 42 AFM TR–MAM–42–
111/a, dated September 20, 2005, Revision 3
to the Airplane Flight Manual, or any future
revision that incorporates the same
information into the Diamond Aircraft
Industries GmbH Aircraft Airplane Flight
Manual DA 42, Doc. 7.01.05–E, immediately
upon receipt. We consider immediately upon
receipt as 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. The time of
60 days after the effective date of this AD is
an adequate compliance for this AD action
and met the FAA requirements of an NPRM
followed by a final rule.
(2) Paragraphs A)i) and B)i) of the MCAI,
state to assure that AFM TR–MAM–42–103,
distributed with DAI MSB42–005, is inserted
into AFM Doc. 7.01.05–E, rev. 2 or earlier
revision. This AFM requirement was for an
MCAI that the United States did not take AD
action on. The action is no longer necessary
when the actions proposed in this NPRM are
done. Therefore, the action is not being
mandated in the U.S. AD action.
(3) The MCAI references revision 2 of the
AFM. However, the current revision level of
the AFM is revision 3. The FAA AD
references revision 3.
Other FAA AD Provisions

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

AGENCY:
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 unsafe condition on an aviation
product. The MCAI describes the unsafe
condition as:
EASA EAD 2006–0072–E was issued on
31st March 2006 following a further failure
of the forward support of the Main Wing
Outboard Flap (MWOF), caused by corrosion.
This condition, if not corrected, may cause
surface twisting during deployment at
landing. The analysis of that event
highlighted the need for the reduction of the
previous inspection interval which was
mandated by ENAC through AD 2004–523,
approved by EASA with reference 2004–
12521.
The proposed AD would require
actions that are intended to address the
unsafe condition described in the MCAI.

SUPPLEMENTARY INFORMATION:
Streamlined Issuance of AD
The FAA is implementing a new
process for streamlining the issuance of
ADs related to MCAI. This streamlined
process will allow us to adopt MCAI
safety requirements in a more efficient
manner and will reduce safety risks to
the public. This process continues to
follow all FAA AD issuance processes to
meet legal, economic, Administrative
Procedure Act, and Federal Register
requirements. We also continue to meet
our technical decision-making
responsibilities to identify and correct
unsafe conditions on U.S.-certificated
products.
This proposed AD references the
MCAI and related service information
that we considered in forming the
engineering basis to correct the unsafe
condition. The proposed AD contains
text copied from the MCAI and for this
reason might not follow our plain
language principles.

Discussion
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Community, has issued AD No. 2006–
0305, dated October 9, 2006 (referred to
after this as ‘‘the MCAI’’), to correct an
unsafe condition for the specified
products. The MCAI states:
EASA EAD 2006–0072–E was issued on
31st March 2006 following a further failure
of the forward support of the Main Wing
Outboard Flap (MWOF), caused by corrosion.
This condition, if not corrected, may cause
surface twisting during deployment at
landing. The analysis of that event
highlighted the need for the reduction of the
previous inspection interval which was
mandated by ENAC through AD 2004–523,
approved by EASA with reference 2004–
12521.
Now the TC holder has developed a new
type of forward support for the Main Wing
Outboard Flap with characteristics that
improve the resistance to corrosion. When
the new support is installed, the repetitive
Eddy current inspection that was introduced
by EASA EAD 2006–0072–E is no longer
required.
You may obtain further information
by examining the MCAI in the AD
docket.
Relevant Service Information
Piaggio Aero Industries S.p.A. has
issued Mandatory Service Bulletin No.
80–0210, Rev. 4, dated July 19, 2006.
The actions described in this service
information are intended to correct the
unsafe condition identified in the
MCAI.
FAA’s Determination and Requirements
of the Proposed AD
This product has been approved by
the aviation authority of another
PO 00000
Frm 00011
Fmt 4702
Sfmt 4702
20299
country, and is approved for operation
in the United States. Pursuant to our
bilateral agreement with this State of
Design Authority, they have notified us
of the unsafe condition described in the
MCAI and service information
referenced above. We are proposing this
AD because we evaluated all
information and determined the unsafe
condition exists and is likely to exist or
develop on other products of the same
type design.
Differences Between This Proposed 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
Based on the service information, we
estimate that this proposed AD would
affect about 7 products of U.S. registry.
We also estimate that it would take
about 16 work-hours per product to
comply with the basic requirements of
this proposed AD. The average labor
rate is $80 per work-hour.
Based on these figures, we estimate
the cost of the proposed AD on U.S.
operators to be $8,960, or $1,280 per
product.
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
E:\FR\FM\24APP1.SGM
24APP1

Federal Register / Vol. 72, No. 78 / Tuesday April 24, 2007 / Proposed Rules
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); 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 proposed AD and placed it in the
AD docket.

SUPPLEMENTARY INFORMATION:
Streamlined Issuance of AD
The FAA is implementing a new process for streamlining the issuance
of ADs related to MCAI. This streamlined process will allow us to adopt
MCAI safety requirements in a more efficient manner and will reduce
safety risks to the public. This process continues to follow all FAA AD
issuance processes to meet legal, economic, Administrative Procedure
Act, and Federal Register requirements. We also continue to meet our
technical decision-making responsibilities to identify and correct
unsafe conditions on U.S.-certificated products.
This proposed AD references the MCAI and related service
information that we considered in forming the engineering basis to
correct the unsafe condition. The proposed AD contains text copied from
the MCAI and for this reason might not follow our plain language
principles.

Discussion
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued AD
No. 2006-0305, dated October 9, 2006 (referred to after this as ``the
MCAI''), to correct an unsafe condition for the specified products. The
MCAI states:
EASA EAD 2006-0072-E was issued on 31st March 2006 following a
further failure of the forward support of the Main Wing Outboard
Flap (MWOF), caused by corrosion. This condition, if not corrected,
may cause surface twisting during deployment at landing. The
analysis of that event highlighted the need for the reduction of the
previous inspection interval which was mandated by ENAC through AD
2004-523, approved by EASA with reference 2004-12521.
Now the TC holder has developed a new type of forward support
for the Main Wing Outboard Flap with characteristics that improve
the resistance to corrosion. When the new support is installed, the
repetitive Eddy current inspection that was introduced by EASA EAD
2006-0072-E is no longer required.
You may obtain further information by examining the MCAI in the AD
docket.
Relevant Service Information
Piaggio Aero Industries S.p.A. has issued Mandatory Service
Bulletin No. 80-0210, Rev. 4, dated July 19, 2006. The actions
described in this service information are intended to correct the
unsafe condition identified in the MCAI.
FAA's Determination and Requirements of the 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 this State of Design Authority, they
have notified us of the unsafe condition described in the MCAI and
service information referenced above. We are proposing this AD because
we evaluated all information and determined the unsafe condition exists
and is likely to exist or develop on other products of the same type
design.
Differences Between This Proposed 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
Based on the service information, we estimate that this proposed AD
would affect about 7 products of U.S. registry. We also estimate that
it would take about 16 work-hours per product to comply with the basic
requirements of this proposed AD. The average labor rate is $80 per
work-hour.
Based on these figures, we estimate the cost of the proposed AD on
U.S. operators to be $8,960, or $1,280 per product.
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
[[Page 20300]]
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); 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 proposed AD and placed it in the AD docket.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, 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:
Piaggio Aero Industries S.p.A.: Docket No. FAA-2007-27723;
Directorate Identifier 2007-CE-029-AD.
Comments Due Date
(a) We must receive comments by May 24, 2007.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Model P-180 airplanes, serial numbers
1002, 1004 through 1107, 1109, and 1110, certificated in any
category.
Subject
(d) Air Transport Association of America (ATA) Code 57: Wings.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
EASA EAD 2006-0072-E was issued on 31st March 2006 following a
further failure of the forward support of the Main Wing Outboard
Flap (MWOF), caused by corrosion. This condition, if not corrected,
may cause surface twisting during deployment at landing. The
analysis of that event highlighted the need for the reduction of the
previous inspection interval which was mandated by ENAC through AD
2004-523, approved by EASA with reference 2004-12521.
Now the TC holder has developed a new type of forward support
for the Main Wing Outboard Flap with characteristics that improve
the resistance to corrosion. When the new support is installed, the
repetitive Eddy current inspection that was introduced by EASA EAD
2006-0072-E is no longer required.
Actions and Compliance
(f) Unless already done, do the following actions:
(1) Within the next 200 hours time-in-service (TIS) or 60 days
after the effective date of this AD, whichever occurs first, replace
the outboard flap track forward bushing and the outboard flap track
forward support. Do the replacements using the Accomplishment
Instructions detailed in Part A of Piaggio Aero Industries S.p.A.
Mandatory Service Bulletin (SB) No. 80-0210, Rev 4, dated July 19,
2006.
(2) At intervals not to exceed 1,500 hours TIS after doing the
replacements required in paragraph (f)(1) of this AD, visually
inspect the outboard flap track forward support for traces of any
kind of corrosion and/or protective coat/finishing wear damage. Do
the inspections using the Accomplishment Instructions detailed in
Part B of Piaggio Aero Industries S.p.A. Mandatory SB No. 80-0210,
Rev 4, dated July 19, 2006.
(3) Before further flight after each inspection required in
paragraph (f)(2) of this AD in which any kind of corrosion or wear
damage is found, contact the manufacturer for a repair scheme and
incorporate the repair.
