ACTION: Proposed rule; corrections.
Administration (GIPSA) in the Federal
Register of April 11, 2012, regarding a
proposal to revise the U.S. Standards for
Wheat under the U.S. Grain Standards

the definition of Contrasting classes in
Hard White wheat and change the grade
limits for shrunken and broken kernels.
GIPSA believes that these proposed
changes will help to facilitate the
marketing of wheat.

AD currently requires revising certain
sections of a certain airplane flight
manual, deactivating certain hydraulic
accumulators, removing certain
hydraulic accumulators, ultrasonic
inspections for cracks on accumulators
and screw caps and replacement if
necessary, and replacing certain
accumulators. Since we issued that AD,
we have determined that, for certain
airplanes, reducing the compliance time
for a certain replacement is necessary to
ensure that the identified unsafe
condition is addressed. This proposed
AD would continue to require the
existing actions from the existing AD.
We are proposing this AD to detect and

FAA’s Determination and Requirements
of This Proposed AD
Discussion
On October 20, 2011, we issued AD
2011–23–08, Amendment 39–16859 (76
FR 71241, November 17, 2011). That AD
required actions intended to address an
unsafe condition on certain Bombardier,
Inc. Model CL–600–2B19 (Regional Jet
Series 100 & 440) Airplanes.
Since we issued AD 2011–23–08,
Amendment 39–16859 (76 FR 71241,
November 17, 2011), we have
determined that the compliance time
specified in paragraph (n) of this
proposed AD (referred to as paragraph
(q) in AD 2011–23–08) must be clarified.
We are including the phrase,
‘‘whichever occurs first,’’ in paragraph
(n)(1) of this AD, which requires
operators to perform the action at the
earlier of the times. We have determined
that the proposed reduced compliance
time is necessary to address the
identified unsafe condition in a timely
manner. This compliance time also
matches the compliance time given in
Canadian Airworthiness Directive CF–
2010–24, dated August 3, 2010.
We have also determined that certain
phrases need to be added and certain
phrases need to be removed from certain
credit paragraphs of this AD. We have
revised paragraphs (o)(4) and (o)(5) of
this proposed AD to specify ‘‘before
December 22, 2011 (the effective date of
AD 2011–23–08, Amendment 39–16859
(76 FR 71241, November 17, 2011)),’’
instead of ‘‘before November 4, 2010.’’
We have revised paragraph (o)(2) of this
AD by removing ‘‘hydraulic system No.
1’’ because the service information in
paragraph (o)(2) does not specify to
remove the hydraulic system No. 1
accumulator. We have also revised
paragraph (o)(2) of this proposed AD by
removing Bombardier Service Bulletin
601R–32–107, Revision A, dated June
17, 2010, because credit for that service
bulletin is already given in paragraph
(m) of this proposed AD. You may
obtain further information by examining
the MCAI in the AD docket.
Changes to Existing AD
PO 00000
Frm 00002
Fmt 4702
Sfmt 4702
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.
This proposed AD would retain all
requirements of AD 2011–23–08,
Amendment 39–16859 (76 FR 71241,
November 17, 2011). Since AD 2011–
23–08 was issued, the AD format has
been revised, and certain paragraphs
have been rearranged. As a result, the
corresponding paragraph identifiers
have changed in this proposed AD, as
listed in the following table:

We have also revised paragraph (j)
(paragraph (j) of AD 2011–23–08,
Amendment 39–16859 (76 FR 71241,
November 17, 2011)) of this proposed
AD to refer to paragraph (k) of this AD
instead of paragraph (l)(1) (paragraph (l)
of AD 2011–23–08) for the applicable
compliance times.
Differences Between This AD and the
MCAI or Service Information
The actions specified in Canadian
Airworthiness Directive CF–2010–24,
dated August 3, 2010, apply only to
Tactair accumulators. The actions
required by paragraphs (h), (i), and (m)
of this proposed AD apply to all
accumulators in the positions specified
in paragraphs (h), (i), and (l) of this
proposed AD.
While Canadian Airworthiness
Directive CF–2010–24, dated August 3,
2010, does not require replacement of
the reducer of the hydraulic system No.

Federal Register / Vol. 77, No. 76 / Thursday, April 19, 2012 / Proposed Rules
1 with a new reducer, paragraph (n) of
this proposed AD does.
Costs of Compliance
Based on the service information, we
estimate that this proposed AD would
affect about 605 products of U.S.
registry.
The actions that are required by AD
2011–23–08, Amendment 39–16859 (76
FR 71241, November 17, 2011), and
retained in this proposed AD take about
33 work-hours per product, at an
average labor rate of $85 per work hour.
Required parts cost about $3,054 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 parts. As we do not control
warranty coverage for affected parties,
some parties may incur costs higher
than estimated here. Based on these
figures, the estimated cost of the
currently required actions is $5,859 per
product.
The new requirements of this
proposed AD add no additional
economic burden.
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.
tkelley on DSK3SPTVN1PROD 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:
VerDate Mar<15>2010
16:50 Apr 18, 2012
Jkt 226001
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);
3. Will not affect intrastate aviation in
Alaska; and
4. 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.

Airworthiness Directives; Bombardier, Inc. Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to supersede an existing airworthiness directive
(AD) that applies to certain Bombardier, Inc. Model CL-600-2B19
(Regional Jet Series 100 & 440) airplanes. The existing AD currently
requires revising certain sections of a certain airplane flight manual,
deactivating certain hydraulic accumulators, removing certain hydraulic
accumulators, ultrasonic inspections for cracks on accumulators and
screw caps and replacement if necessary, and replacing certain
accumulators. Since we issued that AD, we have determined that, for
certain airplanes, reducing the compliance time for a certain
replacement is necessary to ensure that the identified unsafe condition
is addressed. This proposed AD would continue to require the existing
actions from the existing AD. We are proposing this AD to detect and
correct hydraulic accumulator screw cap/end cap failure, which could
result in the loss of the associated hydraulic
[[Page 23421]]
system and high-energy impact damage to adjacent systems and structure,
and consequent loss of control of the airplane.
DATES: We must receive comments on this proposed AD by June 4, 2012.
ADDRESSES: You may send comments by any of the following methods:

SUPPLEMENTARY INFORMATION:
Comments Invited
We invite you to send any written relevant data, views, or
arguments about this proposed AD. Send your comments to an address
listed under the ADDRESSES section. Include ``Docket No. FAA-2012-0420;
Directorate Identifier 2011-NM-284-AD'' at the beginning of your
comments. We specifically invite comments on the overall regulatory,
economic, environmental, and energy aspects of this proposed AD. We
will consider all comments received by the closing date and may amend
this proposed AD based on those comments.
We will post all comments we receive, without change, to https://www.regulations.gov, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we
receive about this proposed AD.
Discussion
On October 20, 2011, we issued AD 2011-23-08, Amendment 39-16859
(76 FR 71241, November 17, 2011). That AD required actions intended to
address an unsafe condition on certain Bombardier, Inc. Model CL-600-
2B19 (Regional Jet Series 100 & 440) Airplanes.
Since we issued AD 2011-23-08, Amendment 39-16859 (76 FR 71241,
November 17, 2011), we have determined that the compliance time
specified in paragraph (n) of this proposed AD (referred to as
paragraph (q) in AD 2011-23-08) must be clarified. We are including the
phrase, ``whichever occurs first,'' in paragraph (n)(1) of this AD,
which requires operators to perform the action at the earlier of the
times. We have determined that the proposed reduced compliance time is
necessary to address the identified unsafe condition in a timely
manner. This compliance time also matches the compliance time given in
Canadian Airworthiness Directive CF-2010-24, dated August 3, 2010.
We have also determined that certain phrases need to be added and
certain phrases need to be removed from certain credit paragraphs of
this AD. We have revised paragraphs (o)(4) and (o)(5) of this proposed
AD to specify ``before December 22, 2011 (the effective date of AD
2011-23-08, Amendment 39-16859 (76 FR 71241, November 17, 2011)),''
instead of ``before November 4, 2010.'' We have revised paragraph
(o)(2) of this AD by removing ``hydraulic system No. 1'' because the
service information in paragraph (o)(2) does not specify to remove the
hydraulic system No. 1 accumulator. We have also revised paragraph
(o)(2) of this proposed AD by removing Bombardier Service Bulletin
601R-32-107, Revision A, dated June 17, 2010, because credit for that
service bulletin is already given in paragraph (m) of this proposed AD.
You may obtain further information by examining the MCAI in the AD
docket.
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.
Changes to Existing AD
This proposed AD would retain all requirements of AD 2011-23-08,
Amendment 39-16859 (76 FR 71241, November 17, 2011). Since AD 2011-23-
08 was issued, the AD format has been revised, and certain paragraphs
have been rearranged. As a result, the corresponding paragraph
identifiers have changed in this proposed AD, as listed in the
following table:

We have also revised paragraph (j) (paragraph (j) of AD 2011-23-08,
Amendment 39-16859 (76 FR 71241, November 17, 2011)) of this proposed
AD to refer to paragraph (k) of this AD instead of paragraph (l)(1)
(paragraph (l) of AD 2011-23-08) for the applicable compliance times.
Differences Between This AD and the MCAI or Service Information
The actions specified in Canadian Airworthiness Directive CF-2010-
24, dated August 3, 2010, apply only to Tactair accumulators. The
actions required by paragraphs (h), (i), and (m) of this proposed AD
apply to all accumulators in the positions specified in paragraphs (h),
(i), and (l) of this proposed AD.
While Canadian Airworthiness Directive CF-2010-24, dated August 3,
2010, does not require replacement of the reducer of the hydraulic
system No.
[[Page 23422]]
1 with a new reducer, paragraph (n) of this proposed AD does.
Costs of Compliance
Based on the service information, we estimate that this proposed AD
would affect about 605 products of U.S. registry.
The actions that are required by AD 2011-23-08, Amendment 39-16859
(76 FR 71241, November 17, 2011), and retained in this proposed AD take
about 33 work-hours per product, at an average labor rate of $85 per
work hour. Required parts cost about $3,054 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 parts.
As we do not control warranty coverage for affected parties, some
parties may incur costs higher than estimated here. Based on these
figures, the estimated cost of the currently required actions is $5,859
per product.
The new requirements of this proposed AD add no additional economic
burden.
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);
3. Will not affect intrastate aviation in Alaska; and
4. 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, Incorporation by
reference, 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 removing airworthiness directive
(AD) 2011-23-08, Amendment 39-16859 (76 FR 71241, November 17, 2011),
and adding the following new AD:
Bombardier, Inc.: Docket No. FAA-2012-0420; Directorate Identifier
2011-NM-284-AD.
(a) Comments Due Date
We must receive comments by June 4, 2012.
(b) Affected ADs
This AD supersedes AD 2011-23-08, Amendment 39-16859 (76 FR
71241, November 17, 2011).
(c) Applicability
This AD applies to Bombardier, Inc. Model CL-600-2B19 (Regional

serial numbers 7003 and subsequent.
(d) Subject
Air Transport Association (ATA) of America Code 29, Hydraulic
Power; 32, Landing Gear.
(e) Reason
This AD was prompted by reports of on-ground hydraulic
accumulator screw cap/end cap failure. We are issuing this AD to
detect and correct hydraulic accumulator screw cap/end cap failure,
which could result in the loss of the associated hydraulic system
and high-energy impact damage to adjacent systems and structure, and
consequent loss of control of the airplane.
