AGENCY: Federal Aviation
Administration (FAA), Department of

ACTION: Final rule.
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:
Due to their position on the aeroplane, fuel
fire shut-off valve actuators P/N [part
number] 9409122 are susceptible to freezing,
which has an adverse effect on the operation
of the valve. Also, due to various causes, the
failure rate of [fuel fire shut-off valve]
actuator P/N 9409122 is higher than
expected. Failure or freezing of the actuator
may prevent the flight crew to close the fuel
fire shut-off valve in case of an engine fire.

Due to their position on the aeroplane, fuel
crossfeed valve actuators P/N 9409122 are
susceptible to freezing, which has an adverse

condition, if not corrected, may generate fuel
asymmetry alerts when a valve remains in
the open position after being selected closed.
It may also prevent the flight crew from
correcting a fuel asymmetry when a valve
remains in the closed position after being
selected open. One event was reported
where, due to such problems, the flight crew

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 March 9, 2010 (75 FR
10696). That NPRM proposed to correct
an unsafe condition for the specified
products. The MCAI states:
In-service experience revealed that, due to
their position on the aircraft, ice may form
on actuators P/N 9409122 installed on fuel
crossfeed valves and fuel fire shut-off valves.
Tests revealed that the ice can prevent the
actuator and thus the valve from operating in
flight (frozen stuck). A new actuator is being
developed by Fokker Services. However, an
airworthiness assessment revealed that
interim actions are required for actuators p/
n 9409122 installed on fuel crossfeed valves
and fuel fire shut-off valves until the new
actuators are installed. Fokker Services have
issued Service Bulletin (SB) SBF100–28–049
to introduce interim actions that will reduce
the probability that fuel crossfeed and fuel
PO 00000
Frm 00001
Fmt 4700
Sfmt 4700
fire shut-off valves equipped with actuators
p/n 9409122 do not operate due to ice. The
interim actions consist of an operational
check of the actuators and the application of
a grease layer on the actuators, followed by
a weekly visual check of the applied grease
layer and a 4-weekly operational check of the
actuators.
For the reasons stated above, this
Airworthiness Directive (AD) requires
compliance with instructions contained in
the referenced SB. This AD has been republished to correct typographical errors in
the ‘Remarks’ section, where the word
‘Proposed’ should have been deleted.
EASA AD 2009–0116 states:
Due to their position on the aeroplane, fuel
crossfeed valve actuators P/N 9409122 are
susceptible to freezing, which has an adverse
effect on the operation of the valve. This
condition, if not corrected, may generate fuel
asymmetry alerts when a valve remains in
the open position after being selected closed.
It may also prevent the flight crew from
correcting a fuel asymmetry when a valve
remains in the closed position after being
selected open. One event was reported
where, due to such problems, the flight crew
shut down an engine in-flight and diverted
the aircraft.
Aeroplanes with serial numbers 11244
through 11441 were delivered from the
production line with actuators P/N 9401037
(‘‘chimney type’’) installed. However, on
some aeroplanes, these actuators have
subsequently been replaced in service with
actuators P/N 9409122 (using mounting
blocks P/N 7923505) on one or both fuel
crossfeed valves. As a result, those
aeroplanes are also affected by this unsafe
condition.
To address and correct this unsafe
condition, EASA issued AD 2008–0126 that
required the replacement of all P/N 9409122
fuel crossfeed valve actuators in accordance
with Fokker Services SBF100–28–046 with
new actuators developed by the manufacturer
Eaton Aerospace, P/N 53–0013, which have
improved reliability and are less susceptible
to freezing.
Following the introduction of actuator P/N
53–0013 in service, Eaton Aerospace reported
manufacturing and design errors on actuators
with P/N 53–0013. As a result of these errors,
the top-cap of the actuator may become loose,
possibly leading to actuator failure. Eaton
Aerospace has eliminated these problems by
introducing a new actuator P/N 53–0027 and
Fokker Services have published SBF100–28–
061 to introduce these improved actuators on
aeroplanes.
As the compliance time of EASA AD 2008–
0126 has not yet expired, both P/N 9409122
and P/N 53–0013 fuel crossfeed valve
actuators can currently be installed on
aeroplanes affected by this AD.
For the reasons described above, this EASA
AD retains the requirements of AD 2008–

Federal Register / Vol. 75, No. 120 / Wednesday, June 23, 2010 / Rules and Regulations
0126, which is superseded, and adds the
requirement to install the new P/N 53–0027
actuators. This AD also allows direct
installation of P/N 53–0027 on aeroplanes
that are still in pre-SBF100–28–046
configuration, provided this is done within
the compliance time as established for that
SB in AD 2008–0126 and retained by this
new AD.
EASA AD 2009–0168 states:
Due to their position on the aeroplane, fuel
fire shut-off valve actuators P/N 9409122 are
susceptible to freezing, which has an adverse
effect on the operation of the valve. Also, due
to various causes, the failure rate of actuator
P/N 9409122 is higher than expected. Failure
or freezing of the actuator may prevent the
flight crew to close the fuel fire shut-off valve
in case of an engine fire.
Aeroplanes serial numbers 11244 through
11441 were delivered from the production
line with actuators P/N 9401037 (‘‘chimney
type’’) installed. However, on some
aeroplanes, these actuators have
subsequently been replaced in service with
actuators P/N 9409122 (using mounting
blocks P/N 7923505) on one or both fuel fire
shut-off valves. As a result, those aeroplanes
are also affected by this unsafe condition.
To address and correct this unsafe
condition, EASA issued AD 2008–0193,
requiring the replacement of all P/N 9409122
fuel fire shut-off valve actuators with new
actuators developed by the manufacturer
Eaton Aerospace, P/N 53–0013, which have
improved reliability and are less susceptible
to freezing.
Following the introduction of actuator P/N
53–0013 in service, Eaton Aerospace reported
manufacturing and design errors on actuators
with P/N 53–0013. As a result of these errors,
the top-cap of the actuator may become loose,
possibly leading to actuator failure. Eaton
Aerospace has eliminated these problems by
introducing a new actuator P/N 53–0027 and
Fokker Services have published SBF100–76–
020 to introduce these improved actuators on
aeroplanes.
As a consequence of EASA AD 2008–0193,
both P/N 9409122 and P/N 53–0013 fuel fire
shut-off valve actuators are currently
installed on aeroplanes affected by this AD.
For the reasons described above, this EASA
AD supersedes AD 2008–0193 and requires
the installation of new P/N 53–0027
actuators. This AD also prohibits the
installation of P/N 53–0013 actuators in
accordance with SBF100–76–018 (which has
been cancelled), as previously required by
EASA AD 2008–0193.

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
VerDate Mar<15>2010

Jkt 220001
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 2
products of U.S. registry. We also
estimate that it will take about 23 workhours per product to comply with the
basic requirements of this AD. The
average labor rate is $85 per work-hour.
Required parts will cost about $29,800
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 parts. 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
this AD to the U.S. operators to be
$63,510, or $31,755 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

Reason
(e) The mandatory continuing

three EASA ADs: 2007–0122, dated May 3,
2007 (corrected May 7, 2007); 2009–0116,
dated May 29, 2009; and MCAI 2009–0168,

Airworthiness Directives; The Boeing
Company Model 777–200LR and
–300ER Series Airplanes
AGENCY: Federal Aviation
Administration (FAA), DOT.
ACTION: Final rule.
SUMMARY: We are adopting a new
airworthiness directive (AD) for certain
Model 777–200LR and –300ER series
airplanes. This AD requires doing a high
frequency eddy current inspection for
cracking of the keyway of the fuel tank
access door cutout on the left and right
wings between wing rib numbers 8
(wing station 387) and 9 (wing station
414.5), and related investigative and
corrective actions if necessary. This AD
results from reports of cracks emanating
from the keyway of the fuel tank access
door cutout of the lower wing skin
between wing rib numbers 8 and 9. We
are issuing this AD to prevent loss of the
lower wing skin load path, which could
cause catastrophic structural failure of
the wing.
DATES: This AD is effective July 28,
2010.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in the AD
as of July 28, 2010.

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:
Due to their position on the aeroplane, fuel fire shut-off valve
actuators P/N [part number] 9409122 are susceptible to freezing,
which has an adverse effect on the operation of the valve. Also, due
to various causes, the failure rate of [fuel fire shut-off valve]
actuator P/N 9409122 is higher than expected. Failure or freezing of
the actuator may prevent the flight crew to close the fuel fire
shut-off valve in case of an engine fire.
* * * * *
Due to their position on the aeroplane, fuel crossfeed valve
actuators P/N 9409122 are susceptible to freezing, which has an
adverse effect on the operation of the valve. This condition, if not
corrected, may generate fuel asymmetry alerts when a valve remains
in the open position after being selected closed. It may also
prevent the flight crew from correcting a fuel asymmetry when a
valve remains in the closed position after being selected open. One
event was reported where, due to such problems, the flight crew shut
down an engine in-flight and diverted the aircraft.
* * * * *
* * * [D]ue to their position on the aircraft, ice may form on
actuators P/N 9409122 installed on fuel crossfeed valves and fuel
fire shut-off valves. Tests revealed that the ice can prevent the
actuator and thus the valve from operating in flight (frozen stuck).
* * *
* * * * *
We are issuing this AD to require actions to correct the unsafe
condition on these products.
DATES: This AD becomes effective July 28, 2010.
The Director of the Federal Register approved the incorporation by

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 March 9, 2010 (75 FR
10696). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
In-service experience revealed that, due to their position on
the aircraft, ice may form on actuators P/N 9409122 installed on
fuel crossfeed valves and fuel fire shut-off valves. Tests revealed
that the ice can prevent the actuator and thus the valve from
operating in flight (frozen stuck). A new actuator is being
developed by Fokker Services. However, an airworthiness assessment
revealed that interim actions are required for actuators p/n 9409122
installed on fuel crossfeed valves and fuel fire shut-off valves
until the new actuators are installed. Fokker Services have issued
Service Bulletin (SB) SBF100-28-049 to introduce interim actions
that will reduce the probability that fuel crossfeed and fuel fire
shut-off valves equipped with actuators p/n 9409122 do not operate
due to ice. The interim actions consist of an operational check of
the actuators and the application of a grease layer on the
actuators, followed by a weekly visual check of the applied grease
layer and a 4-weekly operational check of the actuators.
For the reasons stated above, this Airworthiness Directive (AD)
requires compliance with instructions contained in the referenced
SB. This AD has been re-published to correct typographical errors in
the `Remarks' section, where the word `Proposed' should have been
deleted.
EASA AD 2009-0116 states:
Due to their position on the aeroplane, fuel crossfeed valve
actuators P/N 9409122 are susceptible to freezing, which has an
adverse effect on the operation of the valve. This condition, if not
corrected, may generate fuel asymmetry alerts when a valve remains
in the open position after being selected closed. It may also
prevent the flight crew from correcting a fuel asymmetry when a
valve remains in the closed position after being selected open. One
event was reported where, due to such problems, the flight crew shut
down an engine in-flight and diverted the aircraft.
Aeroplanes with serial numbers 11244 through 11441 were
delivered from the production line with actuators P/N 9401037
(``chimney type'') installed. However, on some aeroplanes, these
actuators have subsequently been replaced in service with actuators
P/N 9409122 (using mounting blocks P/N 7923505) on one or both fuel
crossfeed valves. As a result, those aeroplanes are also affected by
this unsafe condition.
To address and correct this unsafe condition, EASA issued AD
2008-0126 that required the replacement of all P/N 9409122 fuel
crossfeed valve actuators in accordance with Fokker Services SBF100-
28-046 with new actuators developed by the manufacturer Eaton
Aerospace, P/N 53-0013, which have improved reliability and are less
susceptible to freezing.
Following the introduction of actuator P/N 53-0013 in service,
Eaton Aerospace reported manufacturing and design errors on
actuators with P/N 53-0013. As a result of these errors, the top-cap
of the actuator may become loose, possibly leading to actuator
failure. Eaton Aerospace has eliminated these problems by
introducing a new actuator P/N 53-0027 and Fokker Services have
published SBF100-28-061 to introduce these improved actuators on
aeroplanes.
As the compliance time of EASA AD 2008-0126 has not yet expired,
both P/N 9409122 and P/N 53-0013 fuel crossfeed valve actuators can
currently be installed on aeroplanes affected by this AD.
For the reasons described above, this EASA AD retains the
requirements of AD 2008-
[[Page 35606]]
0126, which is superseded, and adds the requirement to install the
new P/N 53-0027 actuators. This AD also allows direct installation
of P/N 53-0027 on aeroplanes that are still in pre-SBF100-28-046
configuration, provided this is done within the compliance time as
established for that SB in AD 2008-0126 and retained by this new AD.
EASA AD 2009-0168 states:
Due to their position on the aeroplane, fuel fire shut-off valve
actuators P/N 9409122 are susceptible to freezing, which has an
adverse effect on the operation of the valve. Also, due to various
causes, the failure rate of actuator P/N 9409122 is higher than
expected. Failure or freezing of the actuator may prevent the flight
crew to close the fuel fire shut-off valve in case of an engine
fire.
Aeroplanes serial numbers 11244 through 11441 were delivered
from the production line with actuators P/N 9401037 (``chimney
type'') installed. However, on some aeroplanes, these actuators have
subsequently been replaced in service with actuators P/N 9409122
(using mounting blocks P/N 7923505) on one or both fuel fire shut-
off valves. As a result, those aeroplanes are also affected by this
unsafe condition.
To address and correct this unsafe condition, EASA issued AD
2008-0193, requiring the replacement of all P/N 9409122 fuel fire
shut-off valve actuators with new actuators developed by the
manufacturer Eaton Aerospace, P/N 53-0013, which have improved
reliability and are less susceptible to freezing.
Following the introduction of actuator P/N 53-0013 in service,
Eaton Aerospace reported manufacturing and design errors on
actuators with P/N 53-0013. As a result of these errors, the top-cap
of the actuator may become loose, possibly leading to actuator
failure. Eaton Aerospace has eliminated these problems by
introducing a new actuator P/N 53-0027 and Fokker Services have
published SBF100-76-020 to introduce these improved actuators on
aeroplanes.
As a consequence of EASA AD 2008-0193, both P/N 9409122 and P/N
53-0013 fuel fire shut-off valve actuators are currently installed
on aeroplanes affected by this AD.
For the reasons described above, this EASA AD supersedes AD
2008-0193 and requires the installation of new P/N 53-0027
actuators. This AD also prohibits the installation of P/N 53-0013
actuators in accordance with SBF100-76-018 (which has been
cancelled), as previously required by EASA AD 2008-0193.
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 2 products of U.S. registry.
We also estimate that it will take about 23 work-hours per product to
comply with the basic requirements of this AD. The average labor rate
is $85 per work-hour. Required parts will cost about $29,800 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 parts. 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 this AD to the
U.S. operators to be $63,510, or $31,755 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.

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:
2010-13-11 Fokker Services B.V.: Amendment 39-16342. Docket No. FAA-
2010-0220; Directorate Identifier 2008-NM-166-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective July 28,
2010.
[[Page 35607]]
Affected ADs
(b) None.
Applicability
(c) This AD applies to Fokker Services B.V. Model F.28 Mark 0070
and Mark 0100 airplanes, certificated in any category, all serial
numbers, if an actuator having part number (P/N) 9409122 or P/N 53-
0013 is installed on one or both fuel crossfeed valves or one or
both fuel fire shut-off valves.
Subject
(d) Air Transport Association (ATA) of America Code 28 and 76:
Fuel and Engine Controls, respectively.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
consists of three EASA ADs: 2007-0122, dated May 3, 2007 (corrected
May 7, 2007); 2009-0116, dated May 29, 2009; and MCAI 2009-0168,
dated August 3, 2009. EASA AD 2007-0122 states:
In-service experience revealed that, due to their position on
the aircraft, ice may form on actuators P/N 9409122 installed on
fuel crossfeed valves and fuel fire shut-off valves. Tests revealed
that the ice can prevent the actuator and thus the valve from
operating in flight (frozen stuck). A new actuator is being
developed by Fokker Services. However, an airworthiness assessment
revealed that interim actions are required for actuators p/n 9409122
installed on fuel crossfeed valves and fuel fire shut-off valves
until the new actuators are installed. Fokker Services have issued
Service Bulletin (SB) SBF100-28-049 to introduce interim actions
that will reduce the probability that fuel crossfeed and fuel fire
shut-off valves equipped with actuators p/n 9409122 do not operate
due to ice. The interim actions consist of an operational check of
the actuators and the application of a grease layer on the
actuators, followed by a weekly visual check of the applied grease
layer and a 4-weekly operational check of the actuators.
For the reasons stated above, this Airworthiness Directive (AD)
requires compliance with instructions contained in the referenced
SB. This AD has been re-published to correct typographical errors in
the `Remarks' section, where the word `Proposed' should have been
deleted.
EASA AD 2009-0116 states:
Due to their position on the aeroplane, fuel crossfeed valve
actuators P/N 9409122 are susceptible to freezing, which has an
adverse effect on the operation of the valve. This condition, if not
corrected, may generate fuel asymmetry alerts when a valve remains
in the open position after being selected closed. It may also
prevent the flight crew from correcting a fuel asymmetry when a
valve remains in the closed position after being selected open. One
event was reported where, due to such problems, the flight crew shut
down an engine in-flight and diverted the aircraft.
Aeroplanes with serial numbers 11244 through 11441 were
delivered from the production line with actuators P/N 9401037
(``chimney type'') installed. However, on some aeroplanes, these
actuators have subsequently been replaced in service with actuators
P/N 9409122 (using mounting blocks P/N 7923505) on one or both fuel
crossfeed valves. As a result, those aeroplanes are also affected by
this unsafe condition.
To address and correct this unsafe condition, EASA issued AD
2008-0126 that required the replacement of all P/N 9409122 fuel
crossfeed valve actuators in accordance with Fokker Services SBF100-
28-046 with new actuators developed by the manufacturer Eaton
Aerospace, P/N 53-0013, which have improved reliability and are less
susceptible to freezing.
Following the introduction of actuator P/N 53-0013 in service,
Eaton Aerospace reported manufacturing and design errors on
actuators with P/N 53-0013. As a result of these errors, the top-cap
of the actuator may become loose, possibly leading to actuator
failure. Eaton Aerospace has eliminated these problems by
introducing a new actuator P/N 53-0027 and Fokker Services have
published SBF100-28-061 to introduce these improved actuators on
aeroplanes.
As the compliance time of EASA AD 2008-0126 has not yet expired,
both P/N 9409122 and P/N 53-0013 fuel crossfeed valve actuators can
currently be installed on aeroplanes affected by this AD.
For the reasons described above, this EASA AD retains the
requirements of AD 2008-0126, which is superseded, and adds the
requirement to install the new P/N 53-0027 actuators. This AD also
allows direct installation of P/N 53-0027 on aeroplanes that are
still in pre-SBF100-28-046 configuration, provided this is done
within the compliance time as established for that SB in AD 2008-
0126 and retained by this new AD.
EASA AD 2009-0168 states:
Due to their position on the aeroplane, fuel fire shut-off valve
actuators P/N 9409122 are susceptible to freezing, which has an
adverse effect on the operation of the valve. Also, due to various
causes, the failure rate of actuator P/N 9409122 is higher than
expected. Failure or freezing of the actuator may prevent the flight
crew to close the fuel fire shut-off valve in case of an engine
fire.
Aeroplanes serial numbers 11244 through 11441 were delivered
from the production line with actuators P/N 9401037 (``chimney
type'') installed. However, on some aeroplanes, these actuators have
subsequently been replaced in service with actuators P/N 9409122
(using mounting blocks P/N 7923505) on one or both fuel fire shut-
off valves. As a result, those aeroplanes are also affected by this
unsafe condition.
To address and correct this unsafe condition, EASA issued AD
2008-0193, requiring the replacement of all P/N 9409122 fuel fire
shut-off valve actuators with new actuators developed by the
manufacturer Eaton Aerospace, P/N 53-0013, which have improved
reliability and are less susceptible to freezing.
Following the introduction of actuator P/N 53-0013 in service,
Eaton Aerospace reported manufacturing and design errors on
actuators with P/N 53-0013. As a result of these errors, the top-cap
of the actuator may become loose, possibly leading to actuator
failure. Eaton Aerospace has eliminated these problems by
introducing a new actuator P/N 53-0027 and Fokker Services have
published SBF100-76-020 to introduce these improved actuators on
aeroplanes.
As a consequence of EASA AD 2008-0193, both P/N 9409122 and P/N
53-0013 fuel fire shut-off valve actuators are currently installed
on aeroplanes affected by this AD.
For the reasons described above, this EASA AD supersedes AD
2008-0193 and requires the installation of new P/N 53-0027
actuators. This AD also prohibits the installation of P/N 53-0013
actuators in accordance with SBF100-76-018 (which has been
cancelled), as previously required by EASA AD 2008-0193.
Compliance
(f) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
