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:

SUMMARY:
Incomplete accomplishment instructions
in SB [service bulletin] ATR72–27–1059
original issue and Revision 1, failed to
mention installation of cotter pins to secure
the self locking nuts after re-installation of
the modified Pitch Uncoupling Mechanism
(PUM), when connecting the elevator control
linkage rods to the PUM input levers and the
PUM output rods to the elevator bellcranks
(on both sides).
Because of the non-installation of these
four cotter pins, the fail-safe criteria of the
design requirements on the pitch control are
no longer met. Such a failure could cause the
loss of one self locking nut and would result
in the loss of pitch control on one side—
Captain or First Officer—or the loss of
control of one elevator surface. The
symmetrical loss of two concerned selflocking nuts could lead to a complete loss of
the pitch control.

Discussion
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Community, has issued EASA
Emergency Airworthiness Directive
2008–0137–E, dated July 23, 2008
(referred to after this as ‘‘the MCAI’’), to
correct an unsafe condition for the
specified products. The MCAI states:
Incomplete accomplishment instructions
in SB [service bulletin] ATR72–27–1059
original issue and Revision 1, failed to
mention installation of cotter pins to secure
the self locking nuts after re-installation of
the modified Pitch Uncoupling Mechanism
(PUM), when connecting the elevator control
linkage rods to the PUM input levers and the
PUM output rods to the elevator bellcranks
(on both sides).
Because of the non-installation of these
four cotter pins, the fail-safe criteria of the
design requirements on the pitch control are
no longer met. Such a failure could cause the
loss of one self locking nut and would result
in the loss of pitch control on one side—
Captain or First Officer—or the loss of
control of one elevator surface. The
symmetrical loss of two concerned selflocking nuts could lead to a complete loss of
the pitch control.
For the reasons stated above, this AD
requires you to check [for] the presence of the
four cotter pins and [perform] their
installation if they are found to be missing.
You may obtain further information
by examining the MCAI in the AD
docket.
Relevant Service Information
ATR has issued Avions de Transport
Regional Service Bulletin ATR72–27–
1059, Revision 02, dated May 19, 2008.
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 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 and service information
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.
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
E:\FR\FM\09OCP1.SGM
09OCP1
59574
Federal Register / Vol. 73, No. 197 / Thursday, October 9, 2008 / Proposed Rules
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 20 products of U.S. registry.
We also estimate that it would take
about 2 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
$3,200, or $160 per product.
Authority for This Rulemaking
jlentini on PROD1PC65 with PROPOSALS
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;
16:07 Oct 08, 2008
Jkt 217001
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.
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.
VerDate Aug<31>2005
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.
§ 39.13
[Amended]
2. The FAA amends § 39.13 by adding
the following new AD:

ATR–GIE Avions De Transport Regional
(Formerly Aerospatiale): Docket No.
FAA–2008–1081; Directorate Identifier
2008–NM–143–AD.
Comments Due Date
(a) We must receive comments by
November 10, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to ATR Model ATR72–
101, –102, –201, –202, –211, –212, and
–212A airplanes, all serial numbers,
certificated in any category; as identified in
paragraphs (c)(1) and (c)(2) of this AD, as
applicable.
(1) This AD applies to airplanes on which
ATR Service Bulletin ATR72–27–1059 was
done in service at original issue, dated
October 3, 2006, or Revision 01, dated March
14, 2007, except as provided by paragraph
(c)(2) of this AD.
(2) This AD does not apply to airplanes on
which Revision 02 of ATR Service Bulletin
ATR72–27–1059 was done in service, or ATR
Modification 05572 was done in production.
Modification 05572 is factory-incorporated
on ATR72–212A airplanes from
manufacturer’s serial number (MSN) 730.

(d) Air Transport Association (ATA) of
America Code 27: Flight controls.
Reason
(e) The mandatory continuing
airworthiness information (MCAI) states:

Incomplete accomplishment instructions
in SB [service bulletin] ATR72–27–1059
original issue and Revision 1, failed to
mention installation of cotter pins to secure
the self locking nuts after re-installation of
the modified Pitch Uncoupling Mechanism
(PUM), when connecting the elevator control
linkage rods to the PUM input levers and the
PUM output rods to the elevator bellcranks
(on both sides).
Because of the non-installation of these
four cotter pins, the fail-safe criteria of the
design requirements on the pitch control are
no longer met. Such a failure could cause the
loss of one self locking nut and would result
in the loss of pitch control on one side—
Captain or First Officer—or the loss of
control of one elevator surface. The
symmetrical loss of two concerned selflocking nuts could lead to a complete loss of
the pitch control.
For the reasons stated above, this AD
requires you to check [for] the presence of the
four cotter pins and [perform] their
installation if they are found to be missing.
Actions and Compliance
(f) Unless already done, do the following
actions.
(1) Within 10 days after the effective date
of this AD: Verify installation of the four
cotter pins securing the nuts of the fastener
assemblies connecting the elevator control
rods to the elevator bellcranks as shown in
Figure 1 of the Accomplishment Instructions
of Avions de Transport Regional Service
Bulletin ATR72–27–1059, Revision 02, dated
May 19, 2008.
(2) If any cotter pin is found missing,
before further flight, install a new cotter pin
with part number MS24665–164 by doing all
the applicable actions in accordance with the
Accomplishment Instructions of Avions de
Transport Regional Service Bulletin ATR72–
27–1059, Revision 02, dated May 19, 2008.
Note 1: For accessing the zone to be
inspected, panels 325BL, 325BR, 327HL,
327KL, 327KR, 327JR, 327JL, 333BB, and
334BB may need to be removed. AMM
(airplane maintenance manual) 06–41–30
contains removal procedures.
(3) Before further flight after
accomplishment of paragraph (f)(2) of this
AD, perform an operational test of the
elevator control as specified in paragraph
3.D., ‘‘Tests,’’ of the Accomplishment
Instructions of Avions de Transport Regional
Service Bulletin ATR72–27–1059, Revision
02, dated May 19, 2008. If any elevator
control rod fails the operational test, before
further flight, repair using a method
approved by the Manager, International
Branch, ANM–116, Transport Airplane
Directorate, FAA; or the European Aviation
Safety Agency (EASA) (or its delegated
agent).
FAA AD Differences
Note 2: This AD differs from the MCAI
and/or service information as follows:
The MCAI does not specify corrective
action for failure of the operational test
(binding or friction) specified in paragraph
(f)(3) of this AD. This AD requires using a
method approved by the Manager,
International Branch, ANM–116 or the EASA
E:\FR\FM\09OCP1.SGM
09OCP1
Federal Register / Vol. 73, No. 197 / Thursday, October 9, 2008 / Proposed Rules
(or its delegated agent) and performing
corrective action before further flight.
§1.336–3
Other FAA AD Provisions
(g) The following provisions also apply to
this AD:
(1) Alternative Methods of Compliance
(AMOCs): The Manager, International
Branch, ANM–116, 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: Tom Rodriguez,
Aerospace Engineer, International Branch,
ANM–116, Transport Airplane Directorate,
FAA, 1601 Lind Avenue, SW., Renton,
Washington 98057–3356; telephone (425)
227–1137; fax (425) 227–1149. 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,
the Office of Management and Budget (OMB)
has approved the information collection
requirements and has assigned OMB Control

SUMMARY: This document contains
proposed regulations under sections
402(f), 411(a)(11), and 417 of the
Internal Revenue Code (Code). The
proposed regulations would provide
that the notice required under section
411(a)(11) to be provided to a
participant of his or her right, if any, to
defer receipt of an immediately
distributable benefit must also describe
the consequences of failing to defer
receipt of the distribution. The proposed
regulations would also provide that the
applicable election period for waiving
the qualified joint and survivor annuity
form of benefit under section 417 is the
180-day period ending on the annuity
starting date, and that a notice required
to be provided under section 402(f),
section 411(a)(11), or section 417 may
be provided to a participant as much as
180 days before the annuity starting date
(or, for a notice under section 402(f), the
distribution date). These regulations
would affect administrators of,
employers maintaining, participants in,
and beneficiaries of tax-favored
retirement plans.

locking nut and would result in the loss of pitch control on one
side--Captain or First Officer--or the loss of control of one
elevator surface. The symmetrical loss of two concerned self-locking
nuts could lead to a complete loss of the pitch control.
For the reasons stated above, this AD requires you to check
[for] the presence of the four cotter pins and [perform] their
installation if they are found to be missing.
You may obtain further information by examining the MCAI in the AD
docket.
Relevant Service Information
ATR has issued Avions de Transport Regional Service Bulletin ATR72-
27-1059, Revision 02, dated May 19, 2008. 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 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 and service
information 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.
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
[[Page 59574]]
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 20 products of U.S. registry. We also estimate that
it would take about 2 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 $3,200, or $160 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 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:
ATR-GIE Avions De Transport R[eacute]gional (Formerly Aerospatiale):
Docket No. FAA-2008-1081; Directorate Identifier 2008-NM-143-AD.
Comments Due Date
(a) We must receive comments by November 10, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to ATR Model ATR72-101, -102, -201, -202, -
211, -212, and -212A airplanes, all serial numbers, certificated in
any category; as identified in paragraphs (c)(1) and (c)(2) of this
AD, as applicable.
(1) This AD applies to airplanes on which ATR Service Bulletin
ATR72-27-1059 was done in service at original issue, dated October
3, 2006, or Revision 01, dated March 14, 2007, except as provided by
paragraph (c)(2) of this AD.
(2) This AD does not apply to airplanes on which Revision 02 of
ATR Service Bulletin ATR72-27-1059 was done in service, or ATR
Modification 05572 was done in production. Modification 05572 is
factory-incorporated on ATR72-212A airplanes from manufacturer's
serial number (MSN) 730.
Subject
(d) Air Transport Association (ATA) of America Code 27: Flight
controls.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
Incomplete accomplishment instructions in SB [service bulletin]
ATR72-27-1059 original issue and Revision 1, failed to mention
installation of cotter pins to secure the self locking nuts after
re-installation of the modified Pitch Uncoupling Mechanism (PUM),
when connecting the elevator control linkage rods to the PUM input
levers and the PUM output rods to the elevator bellcranks (on both
sides).
Because of the non-installation of these four cotter pins, the
fail-safe criteria of the design requirements on the pitch control
are no longer met. Such a failure could cause the loss of one self
locking nut and would result in the loss of pitch control on one
side--Captain or First Officer--or the loss of control of one
elevator surface. The symmetrical loss of two concerned self-locking
nuts could lead to a complete loss of the pitch control.
For the reasons stated above, this AD requires you to check
[for] the presence of the four cotter pins and [perform] their
installation if they are found to be missing.
Actions and Compliance
(f) Unless already done, do the following actions.
(1) Within 10 days after the effective date of this AD: Verify
installation of the four cotter pins securing the nuts of the
fastener assemblies connecting the elevator control rods to the
elevator bellcranks as shown in Figure 1 of the Accomplishment
Instructions of Avions de Transport Regional Service Bulletin ATR72-
27-1059, Revision 02, dated May 19, 2008.
(2) If any cotter pin is found missing, before further flight,
install a new cotter pin with part number MS24665-164 by doing all
the applicable actions in accordance with the Accomplishment
Instructions of Avions de Transport Regional Service Bulletin ATR72-
27-1059, Revision 02, dated May 19, 2008.
Note 1: For accessing the zone to be inspected, panels 325BL,
325BR, 327HL, 327KL, 327KR, 327JR, 327JL, 333BB, and 334BB may need
to be removed. AMM (airplane maintenance manual) 06-41-30 contains
removal procedures.
(3) Before further flight after accomplishment of paragraph
(f)(2) of this AD, perform an operational test of the elevator
control as specified in paragraph 3.D., ``Tests,'' of the
Accomplishment Instructions of Avions de Transport Regional Service
Bulletin ATR72-27-1059, Revision 02, dated May 19, 2008. If any
elevator control rod fails the operational test, before further
flight, repair using a method approved by the Manager, International
Branch, ANM-116, Transport Airplane Directorate, FAA; or the
European Aviation Safety Agency (EASA) (or its delegated agent).
FAA AD Differences
Note 2: This AD differs from the MCAI and/or service information
as follows:
The MCAI does not specify corrective action for failure of the
operational test (binding or friction) specified in paragraph (f)(3)
of this AD. This AD requires using a method approved by the Manager,
International Branch, ANM-116 or the EASA
[[Page 59575]]
(or its delegated agent) and performing corrective action before
further flight.
Other FAA AD Provisions
(g) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager,
International Branch, ANM-116, 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: Tom Rodriguez, Aerospace Engineer,
International Branch, ANM-116, Transport Airplane Directorate, FAA,
1601 Lind Avenue, SW., Renton, Washington 98057-3356; telephone
(425) 227-1137; fax (425) 227-1149. 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, the
Office of Management and Budget (OMB) has approved the information
collection requirements and has assigned OMB Control Number 2120-
0056.
