AGENCY: Federal Aviation Administration (FAA), DOT.
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:
The emergency water dump pulley support bracket assembly, Part
Number (P/N) 215-94711-2, has been found cracked or broken on a
number of aeroplanes. Failure of the emergency water dump pulley
support bracket assembly in combination with other system failures
such as an engine failure during take off or pitch control system
jam, may result in a loss of control of the aeroplane.
* * * * *
The proposed AD would require actions that are intended to address
the unsafe condition described in the MCAI.

Discussion
Transport Canada Civil Aviation, which is the aviation authority
for Canada, has issued Canadian Airworthiness Directive CF-2010-38R2,
dated March 17, 2011 (referred to after this as ``the MCAI''), to
correct an unsafe condition for the specified products. The MCAI
states:
The emergency water dump pulley support bracket assembly, Part
Number (P/N) 215-94711-2, has been found cracked or broken on a
number of aeroplanes. Failure of the emergency water dump pulley
support bracket assembly in combination with other system failures
such as an engine failure during take off or pitch control system
jam, may result in a loss of control of the aeroplane.
Revision 2 of this AD is issued to ensure that terminating
action for this AD is carried out prior to the 2011 fire season.
The required actions include a general visual inspection to
determine if either universal solid (round head) rivets or flush rivets
of the bracket assembly of the emergency water dump pulley are
installed; replacing the solid rivets with flush rivets and installing
new stiffeners on the bracket assembly of the emergency water dump
pulley, if necessary; a detailed inspection and a liquid penetrant
inspection of the stiffeners for cracks, deformations, or signs of
corrosion, and replacing the stiffeners with new stiffeners if
necessary; and re-installing the bracket assembly of the emergency
water dump pulley using radius packers. You may obtain further
information by examining the MCAI in the AD docket.
Relevant Service Information
Bombardier, Inc. has issued Service Bulletin 215-A543, Revision 1,
dated June 23, 2010; and Service Bulletin 215-A4424, Revision 2, dated
June 23, 2010. 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 affect about 6 products of U.S. registry. We also estimate that
it would take about 40 work-hours 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 $20,400, or $3,400 per product.
We have received no definitive data that would enable us to provide
a cost estimate for the on-condition actions specified in this AD.
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:
[[Page 34016]]
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.

FAA AD Differences
Note 1: This AD differs from the MCAI and/or service
information as follows:
(1) Although Canadian Airworthiness Directive CF-2010-38R2,
dated March 17, 2011, has a compliance time of ``No later than 01
June 2011,'' for Part II--Terminating Action, this AD has a
compliance time of ``Within 100 flight cycles or 60 days after the
effective date of this AD, whichever occurs first.'' We have
coordinated this difference with Transport Canada Civil Aviation
(TCCA).
(2) Although Canadian Airworthiness Directive CF-2010-38R2,
dated March 17, 2011, has an initial compliance time of ``within 50
flight cycles after the effective date of this AD'' for identifying
the type of rivet installed, this AD has a compliance time of
``within 50 flight cycles or 30 days after the effective date of
this AD, whichever occurs first.'' In addition, the follow-on
inspections in paragraph (i) of this AD for airplanes on which flush
rivets are determined to be installed, is ``within 100 flight cycles
or 60 days after the effective date of this AD, whichever occurs
first.'' We have coordinated this difference with TCCA.
Other FAA AD Provisions
(l) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, New
York Aircraft Certification Office, ANE-170, FAA, has the authority
to approve AMOCs for this AD, if requested using the procedures
found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your
request to your principal inspector or local Flight Standards
District Office, as appropriate. If sending information directly to
the ACO, send it 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, notify your appropriate principal
inspector, or lacking a principal inspector, the manager of the
local flight standards district office/certificate holding 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.
