2007–23–06 CTRM Aviation Sdn. Bhd.
(Formerly Eagle Aircraft (Malaysia)
Sdn. Bhd.): Amendment 39–15252;
Docket No. FAA–2007–28957;
Directorate Identifier 2007–CE–069–AD.
Effective Date
(a) This airworthiness directive (AD)
becomes effective December 11, 2007.
Affected ADs
(b) None.
Applicability
(c) This AD affects Model Eagle 150B
airplanes, all serial numbers, that are
certificated in any category.
Subject
(d) Air Transport Association of America
(ATA) Code 57: Wings.
Reason
(e) The mandatory continuing
airworthiness information (MCAI) states:
An operator has reported severe exfoliation
corrosion on Wing/Canard Flap Hinges, P/N
5731D01–16 (middle and outboard hinges)
on his Eagle 150B. The corrosion has been
detected during 100-hour inspection. The
aircraft has accumulated more than 1000
flight hours. The corrosion is so severe that
one of the Flap Hinges thickness has been
reduced by 50%. The corrosion is not easily
detected because the Flap Hinge is
sandwiched between the Flap Hinge Support
Bracket P/N 5731D01–01.
The failure of the hinge bracket may result
in disintegration of flap/canard wing thus
leading to loss of control, with catastrophic
consequences.
mstockstill on PROD1PC66 with RULES
The MCAI requires you to visually inspect
the flap hinges and flap hinge support
brackets for any corrosion. You are to take
corrective action if you find any corrosion.
Actions and Compliance
(f) Unless already done, do the following
actions:
(1) Within the next 25 hours time-inservice (TIS) after December 11, 2007 (the
effective date of this AD), inspect the flap
hinges and flap hinge support brackets for
any corrosion, following CTRM Aviation
Mandatory Service Bulletin SB 1126, dated
July 19, 2007.
(2) Before further flight, if you find any
corrosion as a result of any inspection
required by paragraph (f)(1) of this AD, take
corrective action following CTRM Aviation
Mandatory Service Bulletin SB 1126, dated
July 19, 2007.

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:
One Fokker 100 (F28 Mark 0100) operator
reported that during maintenance in the APU
(auxiliary power unit) compartment, a
disconnected nut was discovered on one of
the shuttle valves in the deployment lines of
the engine fire-extinguishing system. An
additional check by the operator revealed
that on more aircraft in its fleet, the nuts of
the shuttle valves were incorrectly tightened.
This condition, if not corrected, could result
in failure or deteriorated functioning of the
engine fire-extinguishing system in case of an
engine fire.
We are issuing this AD to require
actions to correct the unsafe condition
on these products.
DATES: This AD becomes effective
December 11, 2007.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in this AD
as of December 11, 2007.

SUPPLEMENTARY INFORMATION:
FOR FURTHER INFORMATION CONTACT:
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 August 31, 2007 (72 FR
50274). That NPRM proposed to correct
an unsafe condition for the specified
products. The MCAI states:
One Fokker 100 (F28 Mark 0100) operator
reported that during maintenance in the APU
(auxiliary power unit) compartment, a
disconnected nut was discovered on one of
the shuttle valves in the deployment lines of
the engine fire-extinguishing system. An
additional check by the operator revealed
that on more aircraft in its fleet, the nuts of
the shuttle valves were incorrectly tightened.
This condition, if not corrected, could result
in failure or deteriorated functioning of the
engine fire-extinguishing system in case of an
engine fire. Since a potentially unsafe
condition has been identified that is likely to
exist or develop on other aircraft of this type
design, this Airworthiness Directive requires
a one-time inspection of the nuts and shuttle
valves in the deployment lines of the engine
fire-extinguishing system in the APU
compartment and corrective actions, as
necessary.
The one-time inspection is intended to
find discrepancies, including
incorrectly installed or tightened nuts,
and signs of leakage, damage, or
corrosion. Corrective actions include
tightening or replacing discrepant nuts
or shuttle valves, as applicable. 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.
mstockstill on PROD1PC66 with RULES
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
VerDate Aug<31>2005
16:30 Nov 05, 2007
Jkt 214001
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 13 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 $1,040, 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

additional check by the operator revealed
that on more aircraft in its fleet, the nuts of
the shuttle valves were incorrectly tightened.
This condition, if not corrected, could result
in failure or deteriorated functioning of the
engine fire-extinguishing system in case of an
engine fire. Since a potentially unsafe
condition has been identified that is likely to
exist or develop on other aircraft of this type
design, this Airworthiness Directive requires
a one-time inspection of the nuts and shuttle
valves in the deployment lines of the engine
fire-extinguishing system in the APU
compartment and corrective actions, as
necessary.
The one-time inspection is intended to find
discrepancies, including incorrectly installed
or tightened nuts, and signs of leakage,
damage or corrosion. Corrective actions
include tightening or replacing discrepant
nuts or shuttle valves, as applicable.
Actions and Compliance
(f) Unless already done, do the following
actions.
(1) Within 6 months after the effective date
of this AD, inspect the nuts on the affected
shuttle valves in accordance with Section 3.,
‘‘Accomplishment Instructions,’’ of Fokker

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 August 31, 2007 (72
FR 50274). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
One Fokker 100 (F28 Mark 0100) operator reported that during
maintenance in the APU (auxiliary power unit) compartment, a
disconnected nut was discovered on one of the shuttle valves in the
deployment lines of the engine fire-extinguishing system. An
additional check by the operator revealed that on more aircraft in
its fleet, the nuts of the shuttle valves were incorrectly
tightened. This condition, if not corrected, could result in failure
or deteriorated functioning of the engine fire-extinguishing system
in case of an engine fire. Since a potentially unsafe condition has
been identified that is likely to exist or develop on other aircraft
of this type design, this Airworthiness Directive requires a one-
time inspection of the nuts and shuttle valves in the deployment
lines of the engine fire-extinguishing system in the APU compartment
and corrective actions, as necessary.
The one-time inspection is intended to find discrepancies, including
incorrectly installed or tightened nuts, and signs of leakage, damage,
or corrosion. Corrective actions include tightening or replacing
discrepant nuts or shuttle valves, as applicable. 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 13 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 $1,040, 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:
2007-23-03 Fokker Services B.V.: Amendment 39-15249. Docket No. FAA-
2007-29064; Directorate Identifier 2007-NM-128-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective December
11, 2007.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Fokker Model F.28 Mark 0070 and 0100
airplanes, all serial numbers; certificated in any category.
Subject
(d) Air Transport Association (ATA) of America Code 26: Fire
protection.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
One Fokker 100 (F28 Mark 0100) operator reported that during
maintenance in the APU (auxiliary power unit) compartment, a
disconnected nut was discovered on one of the shuttle valves in the
deployment lines of the engine fire-extinguishing system. An
[[Page 62564]]
additional check by the operator revealed that on more aircraft in
its fleet, the nuts of the shuttle valves were incorrectly
tightened. This condition, if not corrected, could result in failure
or deteriorated functioning of the engine fire-extinguishing system
in case of an engine fire. Since a potentially unsafe condition has
been identified that is likely to exist or develop on other aircraft
of this type design, this Airworthiness Directive requires a one-
time inspection of the nuts and shuttle valves in the deployment
lines of the engine fire-extinguishing system in the APU compartment
and corrective actions, as necessary.
The one-time inspection is intended to find discrepancies, including
incorrectly installed or tightened nuts, and signs of leakage,
damage or corrosion. Corrective actions include tightening or
replacing discrepant nuts or shuttle valves, as applicable.
Actions and Compliance
(f) Unless already done, do the following actions.
(1) Within 6 months after the effective date of this AD, inspect
the nuts on the affected shuttle valves in accordance with Section
3., ``Accomplishment Instructions,'' of Fokker Service Bulletin
SBF100-26-019, dated January 6, 2006.
(2) When discrepancies are found during the inspection as
required by paragraph (f)(1) of this AD, before next flight, tighten
or replace the affected nuts, or replace the shuttle valves; as
applicable; in accordance with Section 3., ``Accomplishment
Instructions,'' of Fokker Service Bulletin SBF100-26-019, dated
January 6, 2006.
Note 1: Fokker 70/100 Aircraft Maintenance Manual Task 26-21-03-
400-814-A also pertains to this subject.
FAA AD Differences
Note 2: This AD differs from the MCAI and/or service information
as follows: No difference.
