Federal Register / Vol. 75, No. 107 / Friday, June 4, 2010 / Proposed Rules
Small agricultural service firms which
would include processors who are
covered under the Order, have been
defined by the Small Business
Administration (13 CFR 121.607) as
those having annual receipts of no more
than $7 million. Almost 50 percent of
the industry is exempt from paying
assessments. Based on information from
the Board there are currently a total of
40 processors in the industry. Of those,
21 processors pay mandatory
assessments into the program. Of the 21
processors, 11 would be classified as
small processors representing 7 percent
of the popcorn assessed. The top five
popcorn producing states are Nebraska,
Indiana, Illinois, Ohio and Iowa. In
2009, Indiana, Kansas, Michigan and
Ohio had decreases in acreage planted
and harvested while Kentucky, Illinois,
Iowa, Missouri and Nebraska had
increases in acreage planted and
harvested over the acreage planted and
harvested in 2008. Overall 2009 acreage
planted increased by 1 percent and
acreage harvested increased by 4
percent over 2008 numbers.
Most of the processors would be
classified as small businesses under the
criteria established by the Small
Business Administration. Processors
who process and distribute 4 million
pounds or less of popcorn annually are
exempt from this program. Persons that
operate under an approved National
Organics program (NOP) (7 CFR part
206) system plan; process only products
that are eligible to be labeled as 100
percent organic under the NOP and are
not split operations shall be exempt
from the payment of assessments.
The Board currently consists of 9
members which represent small,
medium and large processors in the
industry.
The Board voted during its October 5,
2009, conference call to request that the
Secretary reduce the number of
members from nine to five and to
appoint persons to reflect the
consolidation of the popcorn industry
and therefore, fewer popcorn processors
in the industry who will equitably make
up the board between large, medium
and small processors. The Board would
continue to strive for diversity within
the industry.
Nominations and appointments to the
Board are conducted pursuant to
sections 1215.22, 1215.23, and 1215.25
of the Order. Appointments to the Board
are made by the Secretary from a slate
of nominated candidates. Pursuant to
section 1215.22(3)(i) of the Order,
nominations for each position shall be
made by processors, and be submitted to
the Secretary for appointment to the
Board. The Order requires that two
VerDate Mar<15>2010

Jkt 220001
nominees be submitted for each vacant
position.
The Department has not identified
any relevant Federal rules that
duplicate, overlap, or conflict with this
rule.
Background
The Order became effective on July
22, 1997, and it is authorized under the
Act. The Board is composed of nine
processors. Nominations take into
consideration the geographical
distribution of popcorn production. The
States that currently have representation
on the Board are Nebraska, Indiana,
Iowa, Missouri and Colorado. Based on
information from the Board, in 2008, the
top five popcorn producing states were
Nebraska, Indiana, Illinois, Ohio and
Iowa.
Under the Order, the Board
administers a nationally coordinated
program of promotion, research,
consumer information and industry
information designed to strengthen the
position of popcorn in the marketplace,
and to maintain and expand domestic
and foreign markets and uses for
popcorn. This program is financed by
assessments on processors who process
and distribute 4 million pounds or more
of popcorn annually. The current rate of
assessment is 6 cents per
hundredweight of popcorn. The Order
specifies that processors are responsible
for submitting the assessment to the
Board and maintaining records
necessary to verify their reporting(s).
Processors who processes and
distributes less than 4 million pounds of
popcorn annually are exempt from this
assessment.
On October 5, 2009, the Board voted
to decrease its membership from nine to
five.
A 30-day comment period is provided
to allow interested persons to respond
to this proposal. Thirty days is deemed
appropriate so that the proposed
amendments, if adopted, may be
implemented before the 2010 term of
office expires on December 31, 2010. All
written comments received in response
to this rule by the date specified would
be considered prior to finalizing this
action.
Pursuant to 5 U.S.C. 553, it is also
found that good cause exists for not
postponing the effective date of this
action until thirty days after publication
in the Federal Register because (1) a
final rule needs to be in effect before the
Board makes a call for nominations for
the term of office beginning January 1,
2011.

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:

activated by a dual engine shutdown, could
also result in loss of hydraulic power for the
flight controls [and consequent reduced
ability of the flightcrew to maintain the safe
flight and landing of the airplane].

Discussion
Transport Canada Civil Aviation
(TCCA), which is the aviation authority
for Canada, has issued Canadian
Airworthiness Directive CF–2010–01,
dated January 18, 2010 (referred to after
this as ‘‘the MCAI’’), to correct an unsafe
condition for the specified products.
The MCAI states:
Following five reported cases of balance
washer screw failure on similar RATs [ram
air turbine]/air driven generators installed on
other aircraft types, an investigation by
Hamilton Sundstrand determined that a
specific batch of the screws had a
metallographic non-conformity that
increased their susceptibility to brittle
fracture. Subsequently, it was established
that 187 RATs [Part Number (P/N) GL456–
1101–7 and Hamilton Sundstrand P/Ns in the
762826 series] had non-conforming screws
installed either during production or possibly
PO 00000
Frm 00014

Sfmt 4702
during maintenance or repair at Hamilton
Sundstrand repair stations.
Failure of a balance washer screw can
result in loss of the related balance washer,
with consequent turbine imbalance. Such
imbalance could potentially result in RAT
structural failure (including blade failure),
loss of RAT electrical power and structural
damage to the aircraft and, if deployment was
activated by a dual engine shutdown, could
also result in loss of hydraulic power for the
flight controls [and consequent reduced
ability of the flightcrew to maintain the safe
flight and landing of the airplane].
This [Canadian] directive mandates
checking of the RAT and replacing the
balance washer screws, if required. It also
prohibits future installation of unmodified
RATs.
You may obtain further information by
examining the MCAI in the AD docket.
Relevant Service Information
Bombardier has issued Service
Bulletins 700–24–075 and 700–1A11–
24–014, both Revision 01, both dated
July 15, 2009. 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
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
E:\FR\FM\04JNP1.SGM
04JNP1
31733
Federal Register / Vol. 75, No. 107 / Friday, June 4, 2010 / Proposed Rules
affect about 115 products of U.S.
registry. We also estimate that it would
take about 1 work-hour per product to
comply with the basic requirements of
this proposed AD. The average labor
rate is $85 per work-hour. Based on
these figures, we estimate the cost of the
proposed AD on U.S. operators to be
$9,775, or $85 per product.
We prepared a regulatory evaluation
of the estimated costs to comply with
this proposed AD and placed it in the
AD docket.
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.
The Proposed Amendment
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.

041–AD.
Comments Due Date
(a) We must receive comments by July 19,
2010.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Bombardier, Inc.
Model BD–700–1A10 and BD–700–1A11
airplanes, serial numbers 9002 and
subsequent; certificated in any category.
Subject
(d) Air Transport Association (ATA) of
America Code 24: Electrical power.
Reason
(e) The mandatory continuing
airworthiness information (MCAI) states:
Following five reported cases of balance
washer screw failure on similar RATs [ram
air turbines]/air driven generators installed
on other aircraft types, an investigation by
Hamilton Sundstrand determined that a
specific batch of the screws had a
metallographic non-conformity that
increased their susceptibility to brittle
fracture. Subsequently, it was established
that 187 RATs [Part Number (P/N) GL456–
1101–7 and Hamilton Sundstrand P/Ns in the
762826 series] had non-conforming screws
installed either during production or possibly
during maintenance or repair at Hamilton
Sundstrand repair stations.
Failure of a balance washer screw can
result in loss of the related balance washer,
with consequent turbine imbalance. Such
imbalance could potentially result in RAT
structural failure (including blade failure),
loss of RAT electrical power and structural
damage to the aircraft and, if deployment was
activated by a dual engine shutdown, could
also result in loss of hydraulic power for the
flight controls [and consequent reduced
ability of the flightcrew to maintain the safe
flight and landing of the airplane].
This [Canadian] directive mandates
checking of the RAT and replacing the
balance washer screws, if required. It also
prohibits future installation of unmodified
RATs.
Compliance
(f) You are responsible for having the
actions required by this AD performed within
the compliance times specified, unless the
actions have already been done.
Inspection
(g) For airplanes having serial numbers
9002 through 9380 inclusive: At the earliest
of the times identified in paragraphs (g)(1),
(g)(2), (g)(3) and (g)(4) of this AD, inspect to
determine the serial number of the installed
ram air turbine (RAT), in accordance with the
Accomplishment Instructions of the
applicable service bulletin listed in Table 1
of this AD. This inspection may be
conducted visually, which requires lowering
the RAT. A review of airplane maintenance
records is acceptable in lieu of this
inspection if the serial number of the RAT
can be conclusively determined from that
review.
(1) Within 500 flight hours or 24 months
after the effective date of this AD, whichever
occurs first; or
(2) Prior to the next in-flight or on-ground
functional test of the RAT, whichever occurs
first after the effective date of this AD; or
(3) Prior to the next in-flight or on-ground
operational test of the RAT, whichever
occurs first after the effective date of this AD;
or
(4) Prior to the next scheduled RAT inflight deployment.
(h) If the RAT serial number, as determined
in paragraph (g) of this AD, is not listed in
paragraph 1.A of the applicable service
bulletin listed in Table 1 of this AD, no
further action is required by this AD, except
for paragraph (j) of this AD.

Note 1: This AD differs from the MCAI
and/or service information as follows:
Although Canadian Airworthiness
Directive CF–2010–01, dated January 18,
2010, recommends accomplishing the visual
inspection prior to the next scheduled inflight operational test of the RAT, we have
determined that interval would not address
the identified unsafe condition soon enough
to ensure an adequate level of safety for the
affected fleet in light of the degree of urgency
associated with the subject unsafe condition.
This difference has been coordinated with
Transport Canada Civil Aviation (TCCA).
Other FAA AD Provisions
(k) The following provisions also apply to
this AD:
(1) Alternative Methods of Compliance
(AMOCs): The Manager, New York Aircraft
Certification Office (ACO), ANE–170, 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:

Avenue, Suite 410, Westbury, New York
11590; telephone 516–228–7300; fax 516–
794–5531. Before using any approved AMOC
on any airplane to which the AMOC applies,
notify your principal maintenance inspector
(PMI) or principal avionics inspector (PAI),
as appropriate, or lacking a principal
inspector, your local Flight Standards District
Office. The AMOC approval letter must
specifically reference this AD.
(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

ACTION: Supplemental notice of
proposed rulemaking (NPRM);
reopening of the comment period.
SUMMARY: We are revising an earlier
NPRM 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:
The manufacturer has received a report of
a failed canopy jettison test, during a regular
maintenance check. The investigation
revealed that a cable shroud of the jettison
system protruded the canopy structure,
which probably caused the malfunction.
Inability to jettison the canopy in flight
would prevent evacuation of the aeroplane in
case of need.
The proposed AD would require actions
that are intended to address the unsafe
condition described in the MCAI.
DATES: We must receive comments on
this proposed AD by July 19, 2010.

ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
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:
[[Page 31732]]
Following five reported cases of balance washer screw failure on
similar RATs [ram air turbines]/air driven generators installed on
other aircraft types, an investigation * * * determined that a
specific batch of the screws had a metallographic non-conformity
that increased their susceptibility to brittle fracture. * * *
Failure of a balance washer screw can result in loss of the
related balance washer, with consequent turbine imbalance. Such
imbalance could potentially result in RAT structural failure
(including blade failure), loss of RAT electrical power and
structural damage to the aircraft and, if deployment was activated
by a dual engine shutdown, could also result in loss of hydraulic
power for the flight controls [and consequent reduced ability of the
flightcrew to maintain the safe flight and landing of the airplane].
* * * * *
The proposed AD would require actions that are intended to address the
unsafe condition described in the MCAI.
DATES: We must receive comments on this proposed AD by July 19, 2010.

Discussion
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian Airworthiness Directive CF-
2010-01, dated January 18, 2010 (referred to after this as ``the
MCAI''), to correct an unsafe condition for the specified products. The
MCAI states:
Following five reported cases of balance washer screw failure on
similar RATs [ram air turbine]/air driven generators installed on
other aircraft types, an investigation by Hamilton Sundstrand
determined that a specific batch of the screws had a metallographic
non-conformity that increased their susceptibility to brittle
fracture. Subsequently, it was established that 187 RATs [Part
Number (P/N) GL456-1101-7 and Hamilton Sundstrand P/Ns in the 762826
series] had non-conforming screws installed either during production
or possibly during maintenance or repair at Hamilton Sundstrand
repair stations.
Failure of a balance washer screw can result in loss of the
related balance washer, with consequent turbine imbalance. Such
imbalance could potentially result in RAT structural failure
(including blade failure), loss of RAT electrical power and
structural damage to the aircraft and, if deployment was activated
by a dual engine shutdown, could also result in loss of hydraulic
power for the flight controls [and consequent reduced ability of the
flightcrew to maintain the safe flight and landing of the airplane].
This [Canadian] directive mandates checking of the RAT and
replacing the balance washer screws, if required. It also prohibits
future installation of unmodified RATs.
You may obtain further information by examining the MCAI in the AD
docket.
Relevant Service Information
Bombardier has issued Service Bulletins 700-24-075 and 700-1A11-24-
014, both Revision 01, both dated July 15, 2009. 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 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
[[Page 31733]]
affect about 115 products of U.S. registry. We also estimate that it
would take about 1 work-hour per product to comply with the basic
requirements of this proposed AD. The average labor rate is $85 per
work-hour. Based on these figures, we estimate the cost of the proposed
AD on U.S. operators to be $9,775, or $85 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, 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 adding the following new AD:
Bombardier, Inc.: Docket No. FAA-2010-0548; Directorate Identifier
2010-NM-041-AD.
Comments Due Date
(a) We must receive comments by July 19, 2010.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Bombardier, Inc. Model BD-700-1A10 and
BD-700-1A11 airplanes, serial numbers 9002 and subsequent;
certificated in any category.
Subject
(d) Air Transport Association (ATA) of America Code 24:
Electrical power.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
Following five reported cases of balance washer screw failure on
similar RATs [ram air turbines]/air driven generators installed on
other aircraft types, an investigation by Hamilton Sundstrand
determined that a specific batch of the screws had a metallographic
non-conformity that increased their susceptibility to brittle
fracture. Subsequently, it was established that 187 RATs [Part
Number (P/N) GL456-1101-7 and Hamilton Sundstrand P/Ns in the 762826
series] had non-conforming screws installed either during production
or possibly during maintenance or repair at Hamilton Sundstrand
repair stations.
Failure of a balance washer screw can result in loss of the
related balance washer, with consequent turbine imbalance. Such
imbalance could potentially result in RAT structural failure
(including blade failure), loss of RAT electrical power and
structural damage to the aircraft and, if deployment was activated
by a dual engine shutdown, could also result in loss of hydraulic
power for the flight controls [and consequent reduced ability of the
flightcrew to maintain the safe flight and landing of the airplane].
This [Canadian] directive mandates checking of the RAT and
replacing the balance washer screws, if required. It also prohibits
future installation of unmodified RATs.
Compliance
(f) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Inspection
(g) For airplanes having serial numbers 9002 through 9380
inclusive: At the earliest of the times identified in paragraphs
(g)(1), (g)(2), (g)(3) and (g)(4) of this AD, inspect to determine
the serial number of the installed ram air turbine (RAT), in
accordance with the Accomplishment Instructions of the applicable
service bulletin listed in Table 1 of this AD. This inspection may
be conducted visually, which requires lowering the RAT. A review of
airplane maintenance records is acceptable in lieu of this
inspection if the serial number of the RAT can be conclusively
determined from that review.
(1) Within 500 flight hours or 24 months after the effective
date of this AD, whichever occurs first; or
(2) Prior to the next in-flight or on-ground functional test of
the RAT, whichever occurs first after the effective date of this AD;
or
(3) Prior to the next in-flight or on-ground operational test of
the RAT, whichever occurs first after the effective date of this AD;
or
(4) Prior to the next scheduled RAT in-flight deployment.
(h) If the RAT serial number, as determined in paragraph (g) of
this AD, is not listed in paragraph 1.A of the applicable service
bulletin listed in Table 1 of this AD, no further action is required
by this AD, except for paragraph (j) of this AD.

BD-700-1A10........................... 700-24-075.............. 01 July 15, 2009.
----------------------------------------------------------------------------------------------------------------
(i) If the RAT serial number, determined in paragraph (g) of
this AD, is listed in paragraph 1.A. of the applicable service
bulletin listed in Table 1 of this AD, before further flight,
inspect to determine if the symbol ``24-7'' is marked on the RAT
identification plate, in accordance with the Accomplishment
Instructions of the applicable service bulletin listed in Table 1
[[Page 31734]]
of this AD. A review of airplane maintenance records is acceptable
in lieu of this inspection if the symbol ``24-7'' mark can be
conclusively determined from that review.
(1) If the symbol ``24-7'' is marked on the RAT identification
plate, the balance washer screws have already been replaced and no
further action is required by this AD, except for paragraph (j) of
this AD.
(2) If the symbol ``24-7'' is not marked on the RAT
identification plate, before further flight, replace all balance
washer screws with new balance washer screws, part number MS24667-
14, and mark the RAT identification plate with the symbol ``24-7,''
in accordance with the Accomplishment Instructions of the applicable
service bulletin listed in Table 1 of this AD.
(j) For all airplanes: As of the effective date of this AD, no
person may install on any airplane a replacement or spare RAT (P/N
GL456-1101-7; Hamilton Sundstrand P/Ns in the 762826 series) having
one of the S/Ns listed in paragraph 1.A. of the applicable service
bulletin listed in Table 1 of this AD unless the balance washer
screws have already been replaced and the symbol ``24-7'' is marked
on the RAT identification plate.
FAA AD Differences
Note 1: This AD differs from the MCAI and/or service information
as follows:
Although Canadian Airworthiness Directive CF-2010-01, dated
January 18, 2010, recommends accomplishing the visual inspection
prior to the next scheduled in-flight operational test of the RAT,
we have determined that interval would not address the identified
unsafe condition soon enough to ensure an adequate level of safety
for the affected fleet in light of the degree of urgency associated
with the subject unsafe condition. This difference has been
coordinated with Transport Canada Civil Aviation (TCCA).
Other FAA AD Provisions
(k) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, New
York Aircraft Certification Office (ACO), ANE-170, 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: Program
Manager, Continuing Operational Safety, FAA, New York ACO, 1600
Stewart Avenue, Suite 410, Westbury, New York 11590; telephone 516-
228-7300; fax 516-794-5531. Before using any approved AMOC on any
airplane to which the AMOC applies, notify your principal
maintenance inspector (PMI) or principal avionics inspector (PAI),
as appropriate, or lacking a principal inspector, your local Flight
Standards District Office. The AMOC approval letter must
specifically reference this AD.
(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.
