ACTION: Final rule.
AGENCY:
SUMMARY: We are adopting a new
airworthiness directive (AD) for the
products listed above. This 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:
Reports have been received from Fokker
100 (F28 Mark 0100) operators where the
crew experienced difficulties with roll
control. Analysis suggests that these
phenomena are due to frozen water on the
aileron pulleys that are installed on the
Center Wing Spar and located in the Main
Landing Gear (MLG) wheel bays.
Investigation has confirmed that improper
closure of the aerodynamic seals of the wingto-fuselage fairings above the MLG wheel
bays can cause rainwater, wash-water or deicing fluid to leak onto the affected aileron
pulleys. This condition, if not corrected, can
lead to further incidents of frozen water on
aileron pulleys during operation of the
aircraft, resulting in restricted roll control
and/or higher control forces. * * *
We are issuing this AD to require
actions to correct the unsafe condition
on these products.
DATES: This AD becomes effective April
3, 2008.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in this AD
as of April 3, 2008.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would
apply to the specified products. That
NPRM was published in the Federal
Register on December 11, 2007 (72 FR
70249). That NPRM proposed to correct
an unsafe condition for the specified
products. The MCAI states:
yshivers on PROD1PC62 with RULES
Reports have been received from Fokker
100 (F28 Mark 0100) operators where the
crew experienced difficulties with roll
control. Analysis suggests that these
phenomena are due to frozen water on the
aileron pulleys that are installed on the
Center Wing Spar and located in the Main
Landing Gear (MLG) wheel bays.
Investigation has confirmed that improper
closure of the aerodynamic seals of the wingto-fuselage fairings above the MLG wheel
bays can cause rainwater, wash-water or deicing fluid to leak onto the affected aileron
pulleys. [The aileron pulleys on Model F.28
Mark 0070 airplanes are identical to those
installed on the Model F.28 Mark 0100
airplanes. Therefore, those Model F.28 Mark
0070 airplanes may be subject to the unsafe
condition revealed on the Model F.28 Mark
0100 airplanes.] This condition, if not
corrected, can lead to further incidents of
frozen water on aileron pulleys during
operation of the aircraft, resulting in
restricted roll control and/or higher control
forces. Since an unsafe condition has been
identified that is likely to exist or develop on
other aircraft of the same type design, this
Airworthiness Directive requires the
inspection of the wing-to-fuselage fairings
and, if necessary, the accomplishment of
appropriate corrective action(s).
The inspection is intended to find
indications of incorrect fit, damage, or
wear. Corrective actions include a
related investigative action (inspecting
for incorrect fit, damage, or wear of the
aerodynamic seal of the fairings, and
inspecting for damage or wear of the
abrasion resistant coating on the mating
surface of the fuselage skin), restoring
damaged abrasion-resistant coatings,
correcting fairing positions, and
replacing damaged fairing seals. You
may obtain further information by
examining the MCAI in the AD docket.

Comments
We gave the public the opportunity to
participate in developing this AD. We
received no comments on the NPRM or
on the determination of the cost to the
public.
Conclusion
We reviewed the available data and
determined that air safety and the
public interest require adopting the AD
as proposed.
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 required different
actions in this AD from those in the
MCAI in order to follow our FAA
policies. Any such differences are
highlighted in a NOTE within the AD.
Costs of Compliance
We estimate that this AD will affect
about 12 products of U.S. registry. We
also estimate that it will take about 1
work-hour per product to comply with
the basic requirements of this AD. The
average labor rate is $80 per work-hour.
Based on these figures, we estimate the
cost of this AD to the U.S. operators to
be $960, or $80 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 AD will not
have federalism implications under
Executive Order 13132. This AD will
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 AD:
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 AD and placed it in the AD docket.
Examining the AD Docket
You may examine the AD docket on
the Internet at https://
www.regulations.gov; or in person at the
Docket Operations office between 9 a.m.
and 5 p.m., Monday through Friday,
except Federal holidays. The AD docket
contains the NPRM, the regulatory
evaluation, any comments received, and
other information. The street address for
the Docket Operations office (telephone
(800) 647–5527) is in the ADDRESSES
section. Comments will be available in
the AD docket shortly after receipt.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM was published in the Federal Register on December 11, 2007
(72 FR 70249). That NPRM proposed to correct an unsafe condition for
the specified products. The MCAI states:
Reports have been received from Fokker 100 (F28 Mark 0100)
operators where the crew experienced difficulties with roll control.
Analysis suggests that these phenomena are due to frozen water on
the aileron pulleys that are installed on the Center Wing Spar and
located in the Main Landing Gear (MLG) wheel bays. Investigation has
confirmed that improper closure of the aerodynamic seals of the
wing-to-fuselage fairings above the MLG wheel bays can cause
rainwater, wash-water or de-icing fluid to leak onto the affected
aileron pulleys. [The aileron pulleys on Model F.28 Mark 0070
airplanes are identical to those installed on the Model F.28 Mark
0100 airplanes. Therefore, those Model F.28 Mark 0070 airplanes may
be subject to the unsafe condition revealed on the Model F.28 Mark
0100 airplanes.] This condition, if not corrected, can lead to
further incidents of frozen water on aileron pulleys during
operation of the aircraft, resulting in restricted roll control and/
or higher control forces. Since an unsafe condition has been
identified that is likely to exist or develop on other aircraft of
the same type design, this Airworthiness Directive requires the
inspection of the wing-to-fuselage fairings and, if necessary, the
accomplishment of appropriate corrective action(s).
The inspection is intended to find indications of incorrect fit,
damage, or wear. Corrective actions include a related investigative
action (inspecting for incorrect fit, damage, or wear of the
aerodynamic seal of the fairings, and inspecting for damage or wear of
the abrasion resistant coating on the mating surface of the fuselage
skin), restoring damaged abrasion-resistant coatings, correcting
fairing positions, and replacing damaged fairing seals. You may obtain
further information by examining the MCAI in the AD docket.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM or on the determination of
the cost to the public.
Conclusion
We reviewed the available data and determined that air safety and
the public interest require adopting the AD as proposed.
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 required different actions in this AD from those
in the MCAI in order to follow our FAA policies. Any such differences
are highlighted in a NOTE within the AD.
Costs of Compliance
We estimate that this AD will affect about 12 products of U.S.
registry. We also estimate that it will take about 1 work-hour per
product to comply with the basic requirements of this AD. The average
labor rate is $80 per work-hour. Based on these figures, we estimate
the cost of this AD to the U.S. operators to be $960, or $80 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 AD will not have federalism implications
under Executive Order 13132. This AD will 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 AD:
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 AD and placed it in the AD docket.
Examining the AD Docket
You may examine the AD docket on the Internet at https://
www.regulations.gov; or in person at the Docket Operations office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains the NPRM, the regulatory evaluation,
any comments received, and other information. The street address for
the Docket Operations office (telephone (800) 647-5527) is in the
ADDRESSES section. Comments will be available in the AD docket shortly
after receipt.

Adoption of the Amendment
0
Accordingly, under the authority delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
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]
0
2. The FAA amends Sec. 39.13 by adding the following new AD:
2008-04-22 Fokker Services B.V.: Amendment 39-15394. Docket No. FAA-
2007-0300; Directorate Identifier 2007-NM-191-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective April 3,
2008.
[[Page 10652]]
Affected ADs
(b) None.
Applicability
(c) This AD applies to Fokker Model F.28 Mark 0070 and 0100
airplanes, certificated in any category, all serial numbers.
Subject
(d) Air Transport Association (ATA) of America Code 53:
Fuselage.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
Reports have been received from Fokker 100 (F28 Mark 0100)
operators where the crew experienced difficulties with roll control.
Analysis suggests that these phenomena are due to frozen water on
the aileron pulleys that are installed on the Center Wing Spar and
located in the Main Landing Gear (MLG) wheel bays. Investigation has
confirmed that improper closure of the aerodynamic seals of the
wing-to-fuselage fairings above the MLG wheel bays can cause
rainwater, wash-water or de-icing fluid to leak onto the affected
aileron pulleys. [The aileron pulleys on Model F.28 Mark 0070
airplanes are identical to those installed on the Model F.28 Mark
0100 airplanes. Therefore, those Model F.28 Mark 0070 airplanes may
be subject to the unsafe condition revealed on the Model F.28 Mark
0100 airplanes.] This condition, if not corrected, can lead to
further incidents of frozen water on aileron pulleys during
operation of the aircraft, resulting in restricted roll control and/
or higher control forces. Since an unsafe condition has been
identified that is likely to exist or develop on other aircraft of
the same type design, this Airworthiness Directive requires the
inspection of the wing-to-fuselage fairings and, if necessary, the
accomplishment of appropriate corrective action(s).
The inspection is intended to find indications of incorrect fit,
damage, or wear. Corrective actions include a related investigative
action (inspecting for incorrect fit, damage, or wear of the
aerodynamic seal of the fairings, and inspecting for damage or wear
of the abrasion resistant coating on the mating surface of the
fuselage skin), restoring damaged abrasion-resistant coatings,
correcting fairing positions, and replacing damaged fairing seals,
as applicable.
Actions and Compliance
(f) Unless already done, do the following actions.
(1) Within 12 months after the effective date of this AD,
inspect the wing-to-fuselage fairings for indications of incorrect
fit, damage or wear, in accordance with the Accomplishment
Instructions of Fokker Service Bulletin SBF100-53-101, dated
September 30, 2005.
(i) If no indications of incorrect fit, damage or wear are
found, no further action is required by this AD.
(ii) If any incorrect fit, damage or wear is found, before next
flight, do related investigative actions and applicable corrective
actions in accordance with the Accomplishment Instructions of the
service bulletin.
(2) When incorrect fit, damage or wear is found, within 30 days
after the inspection or within 30 days after the effective date of
the AD, whichever occurs later, report the findings to Fokker
Services B.V., Technical Services Dept., P.O. Box 231, 2150 AE
Nieuw-Vennep, The Netherlands.
