<![CDATA[
Federal Register / Vol. 73, No. 93 / Tuesday, May 13, 2008 / Proposed Rules
Regulatory Findings
Reason
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.
(e) The mandatory continuing
airworthiness information (MCAI) states:
Resulting from the assessment of fuel tank
wiring installations required by SFAR 88
(Special Federal Aviation Regulation 88) and
equivalent JAA/EASA (Joint Aviation
Authorities/European Aviation Safety
Agency) policy, BAE Systems identified two
features in the Jetstream 4100 where the need
for design changes was apparent. One of
these is addressed by Service Bulletin (SB)
J41–28–013 which introduces additional
bonding leads between pipes, structures and
various components to improve the electrical
bond paths within the fuel tank areas. This
design change is identified by modification
number JM41659. Additionally, SB J41–28–
013 provides instructions to inspect the
existing bonding leads, to replace any
defective leads and to examine all fuel
system pipe runs in the wings to ensure
appropriate clearances are maintained.
Insufficient or defective bonding in the fuel
tank area, if not corrected, could lead to
ignition of fuel vapours and subsequent fuel
tank explosion.
For the reason stated above, this EASA
Airworthiness Directive (AD) requires the
installation of additional bonding leads,
inspection [for defects] of existing bonding
leads and [for clearance of] all fuel system
pipe runs in the wings and follow-on
corrective actions, as necessary.
Corrective actions include replacing any
defective bonding leads and adjusting
clearances of the fuel system pipe runs.

Discussion
The Civil Aviation Authority of New
Zealand, which is the aviation authority
for New Zealand, has issued AD DCA/
FU24/176C, dated September 27, 2007
(referred to after this as ‘‘the MCAI’’), to
correct an unsafe condition for the
specified products. The MCAI states:
To prevent the possible in-flight failure of
the vertical fin, leading to loss of control of
the aircraft * * *
The MCAI requires inspections of the
vertical fin for cracking, corrosion,
scratches, dents, creases or buckling and
the repair of any damaged area. You
may obtain further information by
examining the MCAI in the AD docket.
Relevant Service Information
The Civil Aviation Authority of New
Zealand, which is the aviation authority
for New Zealand, makes reference to
Pacific Aerospace Limited Chapter 05,
page 25 of the FU–24–950 Series
Maintenance Manual, issued December
1978. The actions described in this
service information are intended to
correct the unsafe condition identified
in the MCAI.
FAA’s Determination and Requirements
of the 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 this State of
Design Authority, they have notified us
of the unsafe condition described in the
MCAI and service information
referenced above. We are proposing this
AD because we evaluated all
information and determined the unsafe
condition exists and is likely to exist or
develop on other products of the same
type design.
Differences Between This Proposed 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
PO 00000
Frm 00006
Fmt 4702
Sfmt 4702
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
We estimate that this proposed AD
will affect 2 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 $80 per work-hour.
Based on these figures, we estimate
the cost of the proposed AD on U.S.
operators to be $160, or $80 per product.
In addition, we estimate that any
necessary follow-on actions would take
about 24 work-hours and require parts
costing $1,000, for a cost of $2,920 per
product. We have no way of
determining the number of products
that may need these actions.
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.

U.S. operators to be $160, or $80 per product.
In addition, we estimate that any necessary follow-on actions would
take about 24 work-hours and require parts costing $1,000, for a cost
of $2,920 per product. We have no way of determining the number of
products that may need these actions.
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.
[[Page 27481]]
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:
Pacific Aerospace Limited: Docket No. FAA-2008-0543; Directorate
Identifier 2007-CE-092-AD.
Comments Due Date
(a) We must receive comments by June 12, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to FU-24 airplanes, all serial numbers,
certificated in any category.
Subject
(d) Air Transport Association of America (ATA) Code 53:
Fuselage.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
To prevent the possible in-flight failure of the vertical fin,
leading to loss of control of the aircraft * * *
The MCAI requires inspections of the vertical fin for cracking,
corrosion, scratches, dents, creases or buckling, and the repair of
any damaged area.
Actions and Compliance
(f) Unless already done, after the effective date of this AD, do
the following actions following Chapter 05, page 25 of the FU-24-950
Series Maintenance Manual:
(1) Before the first flight of the day, visually inspect the
vertical stabilizer leading edge skin and fin for any cracking,
corrosion, scratches, dents, creases or buckling, and repair as
necessary. All non-transparent protective coatings and their
adhesive must be removed for this inspection.
(2) Within 100 hours time-in-service (TIS) after the effective
date of this AD and repetitively thereafter at intervals not to
exceed 100 hours TIS, perform a detailed inspection of the vertical
stabilizer leading edge skin, leading edge, fin skin, and the fin
forward attachment point for any cracking, corrosion, scratches,
dents, creases, or buckling to include:
(i) Inspection of the entire leading edge down to the forward
attach fitting; and removal of dorsal fin extensions if installed in
order to inspect the obscured areas of the fin.
(ii) Inspection of the fin skin for corrosion and cracks, paying
particular attention to the center rib rivet holes and the skin
joint at the fin base.
(iii) Inspection of the fin forward attachment point for
corrosion, removal of the fin tip, and inspection of the top rib for
cracks at the skin stiffener cut outs.
(3) If any damage is found during any inspection required in
paragraph (f)(1) or (f)(2) of this AD, before further flight, obtain
an FAA-approved repair scheme from the manufacturer and incorporate
that repair.
(4) The following transparent polyurethane protective tapes have
been assessed as suitable for use to re-protect the leading edge and
may remain in situ for subsequent inspections, provided they are
sound and in a condition to permit visual inspection of the skin
beneath them:
------------------------------------------------------------------------
Manufacturer Product
------------------------------------------------------------------------
(i) 3M.................................... 8591, or 8671, 8672 and
8681HS (aeronautical
grade).
(ii) Scapa................................ Aeroshield P2604
(transparent).
------------------------------------------------------------------------
Note 1: You may apply for an alternative method of compliance
(AMOC) for an alternative to the transparent polyurethane protective
tapes listed above.
FAA AD Differences
Note 2: This AD differs from the MCAI and/or service information
as follows:
(1) The inspections required in this AD must be performed by a
person authorized under 14 CFR part 43 to perform inspections, as
opposed to the MCAI, which allows the holder of a pilot license to
perform the inspections.
(2) The 50-hour inspection required in the MCAI goes away
because the ``before each flight'' inspection captures the intent.
Other FAA AD Provisions
(g) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager,
Standards Office, 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: Karl Schletzbaum, Aerospace Engineer, FAA,
Small Airplane Directorate, 901 Locust, Room 301, Kansas City,
Missouri 64106; telephone: (816) 329-4146; fax: (816) 329-4090.
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 (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.
