ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
We propose to adopt a new
airworthiness directive (AD) for the
products listed above. This proposed
AD results from mandatory continuing
airworthiness information (MCAI)
issued 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:
pwalker on PROD1PC71 with PROPOSALS
SUMMARY:
There are four ECS (environmental control
system) grilles located in the flight deck side
consoles. There have been occurrences where
a grille has become detached during flight.
There is a risk that a loose grille could foul
the rudder pedals and interfere with rudder/
brake control resulting in an unsafe
condition.
The unsafe condition is a rudder pedal
restriction or jam, which could result in
reduced controllability of the airplane.
The proposed AD would require actions

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

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.

Discussion
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Community, has issued EASA
Airworthiness Directive 2006–0342,
dated November 9, 2006 (referred to
after this as ‘‘the MCAI’’), to correct an
unsafe condition for the specified
products. The MCAI states:
There are four ECS (environmental control
system) grilles located in the flight deck side
consoles. There have been occurrences where
a grille has become detached during flight.
There is a risk that a loose grille could foul
the rudder pedals and interfere with rudder/
brake control resulting in an unsafe
condition.
The unsafe condition is a rudder pedal
restriction or jam, which could result in
reduced controllability of the airplane.
The MCAI requires modifying the
grilles. You may obtain further
information by examining the MCAI in
the AD docket.
Relevant Service Information
BAE Systems (Operations) Limited
has issued Modification Service
Bulletins SB.25–495–60730A, dated
March 14, 2006; and Revision 1, dated
May 9, 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 This Proposed AD
This product has been approved by
the aviation authority of another
country, and is approved for operation

Applicability
(c) This AD applies to BAE Systems
(Operations) Limited Model BAe 146–100A,
–200A, and –300A series airplanes, and
Model Avro 146–RJ70A, 146–RJ85A, and
146–RJ100A airplanes; certificated in any
category; which have modification

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.
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.
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.
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.
There are four ECS (environmental control
system) grilles located in the flight deck side
consoles. There have been occurrences where
a grille has become detached during flight.
There is a risk that a loose grille could foul
the rudder pedals and interfere with rudder/
brake control resulting in an unsafe
condition.
List of Subjects in 14 CFR Part 39
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: Todd Thompson,
Aerospace Engineer, International Branch,
ANM–116, FAA, Transport Airplane
Directorate, 1601 Lind Avenue, SW., Renton,
Washington 98057–3356; telephone (425)
227–1175; (425) 227–1149. Before using any
AMOC approved in accordance with § 39.19
on any airplane to which the AMOC applies,
notify the appropriate principal inspector in
the FAA Flight Standards Certificate Holding
District Office.
(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
pwalker on PROD1PC71 with PROPOSALS
Costs of Compliance
Based on the service information, we
estimate that this proposed AD would
affect about 10 products of U.S. registry.
We also estimate that it would take
about 3 work-hours per product to
comply with the basic requirements of
this proposed AD. The average labor
rate is $80 per work-hour. Required
parts would cost about $6,893 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 costs. As we do not control
warranty coverage for affected parties,
some parties may incur costs higher
than estimated here. Based on these
figures, we estimate the cost of the
proposed AD on U.S. operators to be
$71,330, or $7,133 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

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) issued 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:
There are four ECS (environmental control system) grilles
located in the flight deck side consoles. There have been
occurrences where a grille has become detached during flight. There
is a risk that a loose grille could foul the rudder pedals and
interfere with rudder/brake control resulting in an unsafe
condition.
The unsafe condition is a rudder pedal restriction or jam, which could
result in reduced controllability of the airplane. The proposed AD
would require actions that are intended to address the unsafe condition
described in the MCAI.

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 10 products of U.S. registry. We also estimate that
it would take about 3 work-hours per product to comply with the basic
requirements of this proposed AD. The average labor rate is $80 per
work-hour. Required parts would cost about $6,893 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
costs. As we do not control warranty coverage for affected parties,
some parties may incur costs higher than estimated here. Based on these
figures, we estimate the cost of the proposed AD on U.S. operators to
be $71,330, or $7,133 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:
BAE Systems (Operations) Limited (Formerly British Aerospace
Regional Aircraft): Docket No. FAA-2007-27714; Directorate
Identifier 2006-NM-277-AD.
Comments Due Date
(a) We must receive comments by April 27, 2007.
Affected ADs
(b) None.
Applicability
(c) This AD applies to BAE Systems (Operations) Limited Model
BAe 146-100A, -200A, and -300A series airplanes, and Model Avro 146-
RJ70A, 146-RJ85A, and 146-RJ100A airplanes; certificated in any
category; which have modification HCM00674A embodied.
Reason
(d) The mandatory continuing airworthiness information (MCAI)
states:
There are four ECS (environmental control system) grilles
located in the flight deck side consoles. There have been
occurrences where a grille has become detached during flight. There
is a risk that a loose grille could foul the rudder pedals and
interfere with rudder/brake control resulting in an unsafe
condition.
The unsafe condition is a rudder pedal restriction or jam, which
could result in reduced controllability of the airplane. The MCAI
requires modifying the grilles.
Subject
(e) Equipment/Furnishings.
Actions and Compliance
(f) Within 6 months after the effective date of this AD, unless
already done, carry out the modification of the ECS grilles as
described in BAE Systems (Operations) Limited Modification Service
Bulletin SB.25-495-60730A, dated March 14, 2006; or Revision 1,
dated May 9, 2006.
FAA AD Differences
Note: This AD differs from the MCAI and/or service information
as follows: No Differences.
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: Todd Thompson, Aerospace Engineer,
International Branch, ANM-116, FAA, Transport Airplane Directorate,
1601 Lind Avenue, SW., Renton, Washington 98057-3356; telephone
(425) 227-1175; (425) 227-1149. Before using any AMOC approved in
accordance with Sec. 39.19 on any airplane to which the AMOC
applies, notify the appropriate principal inspector in the FAA
Flight Standards Certificate Holding District Office.
(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
[[Page 14502]]
