Airworthiness Directives; Fokker
Services B.V. Airplanes
Federal Aviation
Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
AGENCY:
We are superseding two
existing airworthiness directives (ADs)
for certain Fokker Services B.V. Model
F.28 Mark 0100 airplanes. The first
existing AD currently requires removing
the actuator from the fuel-balance
transfer-valve (FBTV) and installing a
locking device on the FBTV. The second
existing AD currently requires
inspecting to verify that the position
indicator of the FBTV is in the closed
position and deactivating the fuelbalance transfer-system. This new AD
requires installing an FBTV locking
device. This AD was prompted by
reports that the FBTV was inadvertently
reactivated after required de-activation
measures were undone. We are issuing
this AD to prevent fuel starvation and a
consequent double-engine flameout,
possibly resulting in a forced landing,
damage to the airplane, and injury to
occupants.
DATES: This AD becomes effective
November 5, 2012.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in this AD
as of November 5, 2012.
The Director of the Federal Register
approved the incorporation by reference
of a certain other publication, listed in
this AD as of April 29, 1996 (61 FR

The Director of the Federal Register

of a certain other publication, listed in
this AD as of August 10, 1994 (59 FR

SUPPLEMENTARY INFORMATION:
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 June 6, 2012 (77 FR 33332),
and proposed to supersede AD 94–14–
05, Amendment 39–8957 (59 FR 35237,
July 11, 1994); and AD 96–07–06,
Amendment 39–9555 (61 FR 14014,
March 29, 1996). That NPRM proposed
to correct an unsafe condition for the
specified products. The MCAI states:
Some Fokker F28 Mark 0100 (Fokker 100)
aeroplanes were delivered from the
production line with a Fuel-Balance
Transfer-System (FBTS) installed. Other
Fokker 100 aeroplanes were delivered with
only FBTS provisions and for some of those,
an option existed for in-service activation of
the FBTS, through Fokker Service Bulletin
(SB) SBF100–28–021.
The FBTS was designed to be used during
maintenance activities to move the Centre of
Gravity (CG) forward by transferring fuel
from the main tanks to the centre tank
through the crossfeed system and a FuelBalance Transfer-Valve (FBTV).
In 1993, a dormant failure mode was
discovered, which could lead to fuel
starvation and consequently to a double
engine flame-out, possibly resulting in a
forced landing, damage to the aeroplane and
injury to occupants. To address and correct
this unsafe condition, CAA–NL [Civil
Aviation Authority—Netherlands] issued AD
BLA 93–160, which required modification of
the FBTV (Fokker SBF100–28–029) [which
corresponds to FAA AD 94–14–05,
Amendment 39–8957 (59 FR 35237, July 11,
1994)], and later BLA 94–146, which
required deactivation of the FBTS (Fokker
SBF100–28–030) [which corresponds to FAA
AD 96–07–06, Amendment 39–9555 (61 FR
14014, March 29, 1996)].
Recently, one operator reported that on two
aeroplanes, the FBTS had inadvertently been
reactivated. SBF100–28–030 had been
accomplished on both aeroplanes but
apparently, (some of) the de-activation
measures introduced with that SB were later
made undone. Subsequent investigation also
showed that Fokker SBF100–28–021,
containing instructions for activating the
FBTS, had inadvertently been left active
when SBF100–28–029 and SBF100–28–030
were published. To address this safety
concern, Fokker Services have issued
SBF100–28–066, which introduces a task to
deactivate the FBTS to a greater extent than
previously required. At the same time,
SBF100–28–021 has been cancelled by its
Revision 1.
For the reasons described above, this
[European Aviation Safety Agency (EASA)]
AD retains the requirements of CAA–NL

[airworthiness directives] BLA 93–160 and
BLA 94–146, which are superseded, and
requires the accomplishment of additional
measures to deactivate the FBTS [modify the

device], in accordance with the instructions
of Fokker Services SBF100–28–066.
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 (77
FR 33332, June 6, 2012) 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—except for minor editorial
changes. We have determined that these
minor changes:
• Are consistent with the intent that
was proposed in the NPRM (77 FR
33332, June 6, 2012) for correcting the
unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the NPRM (77 FR 33332,
June 6, 2012).
Costs of Compliance
We estimate that this AD will affect 2
products of U.S. registry.
The actions that were required by AD
94–14–05, Amendment 39–8957 (59 FR
35237, July 11, 1994), and retained in
this AD take about 1 work-hour per
product, at an average labor rate of $85
per work hour. Required parts cost
about $250 per product. Based on these
figures, the estimated cost of the
currently required actions is $335 per
product.
The actions required by AD 96–07–06,
Amendment 39–9555 (61 FR 14014,
March 29, 1996), and retained in this
AD take about 1 work-hour per product,
at an average labor rate of $85 per work
hour. Required parts cost about $0 per
product. Based on these figures, the
estimated cost of the currently required
actions is $85 per product.
We also estimate that it will take
about 5 work-hours per product to
comply with the new basic
requirements of this AD. The average
labor rate is $85 per work-hour.
Required parts will cost about $650 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
E:\FR\FM\01OCR1.SGM
01OCR1
Federal Register / Vol. 77, No. 190 / Monday, October 1, 2012 / Rules and Regulations
figures, we estimate the cost of this AD
to the U.S. operators to be $2,150, or
$1,075 per product.

section. Comments will be available in
the AD docket shortly after receipt.
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 that 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);
3. Will not affect intrastate aviation in
Alaska; and
4. 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.

inadvertently reactivated after required deactivation measures were undone. We are
issuing this AD to prevent fuel starvation and
a consequent double-engine flameout,
possibly resulting in a forced landing,
damage to the airplane, and injury to
occupants.
(f) Compliance
You are responsible for having the actions
required by this AD performed within the
compliance times specified, unless the
actions have already been done.
(g) Retained Installation of a Locking Device
for the FBTV
This paragraph restates the requirements of
paragraph (a) of AD 94–14–05, Amendment
39–8957 (59 FR 35237, July 11, 1994). For
airplanes having serial numbers 11443,
11446 through 11449 inclusive, and 11456:
Within 30 days after August 10, 1994 (the
effective date of AD 94–14–05), remove the
actuator from the FBTV, part number (P/N)
7933141J and install a locking device on the
FBTV, in accordance with the
Accomplishment Instructions of Fokker
Service Bulletin SBF100–28–029, Revision 1,
dated November 30, 1993.
(h) Retained Inspection and Deactivation
(1) This paragraph restates the
requirements of paragraphs (a) and (b) of AD
96–07–06, Amendment 39–9555 (61 FR
14014, March 29, 1996). For airplanes
identified in Fokker Service Bulletin
SBF100–28–030, Revision 1, dated December
5, 1994: After April 29, 1996 (the effective
date of AD 96–07–06), whenever the fuel
balance transfer system (FBTS) is used
during maintenance, prior to further flight,
perform an inspection to verify that the
position indicator of the FBTV is in the
closed position, in accordance with Fokker
Service Bulletin SBF100–28–030, Revision 1,
dated December 5, 1994. The inspection
requirements of this paragraph must be
accomplished until the deactivation required
by paragraph (h)(2) of this AD is
accomplished.
(i) If the position indicator is in the closed
position, no further action is required by this
paragraph.
(ii) If the position indicator is in the open
position, close the FBTV, in accordance with
the Accomplishment Instructions of Fokker
Service Bulletin SBF100–28–030, Revision 1,
dated December 5, 1994.
(2) Within 90 days after April 29, 1996 (the
effective date of AD 96–07–06, Amendment
39–9555 (61 FR 14014, March 29, 1996)),
deactivate the FBTS in accordance with
either Part 2 or Part 3, as applicable, of the
Accomplishment Instructions of Fokker
Service Bulletin SBF100–28–030, Revision 1,
dated December 5, 1994. Accomplishment of
the deactivation constitutes terminating
action for the repetitive inspection
requirements of paragraph (h)(1) of this AD.
(i) New Requirements of This AD
Within 12 months after the effective date
of this AD, modify the airplane by installing
an FBTV locking device, in accordance with

Airworthiness Directives; Fokker Services B.V. Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are superseding two existing airworthiness directives (ADs)
for certain Fokker Services B.V. Model F.28 Mark 0100 airplanes. The
first existing AD currently requires removing the actuator from the
fuel-balance transfer-valve (FBTV) and installing a locking device on
the FBTV. The second existing AD currently requires inspecting to
verify that the position indicator of the FBTV is in the closed
position and deactivating the fuel-balance transfer-system. This new AD
requires installing an FBTV locking device. This AD was prompted by
reports that the FBTV was inadvertently reactivated after required de-
activation measures were undone. We are issuing this AD to prevent fuel
starvation and a consequent double-engine flameout, possibly resulting
in a forced landing, damage to the airplane, and injury to occupants.
DATES: This AD becomes effective November 5, 2012.
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 June 6, 2012 (77 FR
33332), and proposed to supersede AD 94-14-05, Amendment 39-8957 (59 FR
35237, July 11, 1994); and AD 96-07-06, Amendment 39-9555 (61 FR 14014,
March 29, 1996). That NPRM proposed to correct an unsafe condition for
the specified products. The MCAI states:
Some Fokker F28 Mark 0100 (Fokker 100) aeroplanes were delivered
from the production line with a Fuel-Balance Transfer-System (FBTS)
installed. Other Fokker 100 aeroplanes were delivered with only FBTS
provisions and for some of those, an option existed for in-service
activation of the FBTS, through Fokker Service Bulletin (SB) SBF100-
28-021.
The FBTS was designed to be used during maintenance activities
to move the Centre of Gravity (CG) forward by transferring fuel from
the main tanks to the centre tank through the crossfeed system and a
Fuel-Balance Transfer-Valve (FBTV).
In 1993, a dormant failure mode was discovered, which could lead
to fuel starvation and consequently to a double engine flame-out,
possibly resulting in a forced landing, damage to the aeroplane and
injury to occupants. To address and correct this unsafe condition,
CAA-NL [Civil Aviation Authority--Netherlands] issued AD BLA 93-160,
which required modification of the FBTV (Fokker SBF100-28-029)
[which corresponds to FAA AD 94-14-05, Amendment 39-8957 (59 FR
35237, July 11, 1994)], and later BLA 94-146, which required
deactivation of the FBTS (Fokker SBF100-28-030) [which corresponds
to FAA AD 96-07-06, Amendment 39-9555 (61 FR 14014, March 29,
1996)].
Recently, one operator reported that on two aeroplanes, the FBTS
had inadvertently been reactivated. SBF100-28-030 had been
accomplished on both aeroplanes but apparently, (some of) the de-
activation measures introduced with that SB were later made undone.
Subsequent investigation also showed that Fokker SBF100-28-021,
containing instructions for activating the FBTS, had inadvertently
been left active when SBF100-28-029 and SBF100-28-030 were
published. To address this safety concern, Fokker Services have
issued SBF100-28-066, which introduces a task to deactivate the FBTS
to a greater extent than previously required. At the same time,
SBF100-28-021 has been cancelled by its Revision 1.
For the reasons described above, this [European Aviation Safety
Agency (EASA)] AD retains the requirements of CAA-NL [airworthiness
directives] BLA 93-160 and BLA 94-146, which are superseded, and
requires the accomplishment of additional measures to deactivate the
FBTS [modify the airplane by installing an FBTV locking device], in
accordance with the instructions of Fokker Services SBF100-28-066.
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 (77 FR 33332, June 6,
2012) 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--except for
minor editorial changes. We have determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM (77 FR 33332, June 6, 2012) for correcting the unsafe condition;
and
Do not add any additional burden upon the public than was
already proposed in the NPRM (77 FR 33332, June 6, 2012).
Costs of Compliance
We estimate that this AD will affect 2 products of U.S. registry.
The actions that were required by AD 94-14-05, Amendment 39-8957
(59 FR 35237, July 11, 1994), and retained in this AD take about 1
work-hour per product, at an average labor rate of $85 per work hour.
Required parts cost about $250 per product. Based on these figures, the
estimated cost of the currently required actions is $335 per product.
The actions required by AD 96-07-06, Amendment 39-9555 (61 FR
14014, March 29, 1996), and retained in this AD take about 1 work-hour
per product, at an average labor rate of $85 per work hour. Required
parts cost about $0 per product. Based on these figures, the estimated
cost of the currently required actions is $85 per product.
We also estimate that it will take about 5 work-hours per product
to comply with the new basic requirements of this AD. The average labor
rate is $85 per work-hour. Required parts will cost about $650 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
[[Page 59727]]
figures, we estimate the cost of this AD to the U.S. operators to be
$2,150, or $1,075 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 that 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);
3. Will not affect intrastate aviation in Alaska; and
4. 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 (77 FR 33332, June 6, 2012),
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.

(d) Subject
Air Transport Association (ATA) of America Code 28: Fuel.
(e) Reason
This AD was prompted by reports that the fuel-balance transfer-
valve (FBTV) was inadvertently reactivated after required de-
activation measures were undone. We are issuing this AD to prevent
fuel starvation and a consequent double-engine flameout, possibly
resulting in a forced landing, damage to the airplane, and injury to
occupants.
(f) Compliance
You are responsible for having the actions required by this AD
performed within the compliance times specified, unless the actions
have already been done.
(g) Retained Installation of a Locking Device for the FBTV
This paragraph restates the requirements of paragraph (a) of AD
94-14-05, Amendment 39-8957 (59 FR 35237, July 11, 1994). For
airplanes having serial numbers 11443, 11446 through 11449
inclusive, and 11456: Within 30 days after August 10, 1994 (the
effective date of AD 94-14-05), remove the actuator from the FBTV,
part number (P/N) 7933141J and install a locking device on the FBTV,
in accordance with the Accomplishment Instructions of Fokker Service
Bulletin SBF100-28-029, Revision 1, dated November 30, 1993.
(h) Retained Inspection and Deactivation
(1) This paragraph restates the requirements of paragraphs (a)
and (b) of AD 96-07-06, Amendment 39-9555 (61 FR 14014, March 29,
1996). For airplanes identified in Fokker Service Bulletin SBF100-
28-030, Revision 1, dated December 5, 1994: After April 29, 1996
(the effective date of AD 96-07-06), whenever the fuel balance
transfer system (FBTS) is used during maintenance, prior to further
flight, perform an inspection to verify that the position indicator
of the FBTV is in the closed position, in accordance with Fokker
Service Bulletin SBF100-28-030, Revision 1, dated December 5, 1994.
The inspection requirements of this paragraph must be accomplished
until the deactivation required by paragraph (h)(2) of this AD is
accomplished.
(i) If the position indicator is in the closed position, no
further action is required by this paragraph.
(ii) If the position indicator is in the open position, close
the FBTV, in accordance with the Accomplishment Instructions of
Fokker Service Bulletin SBF100-28-030, Revision 1, dated December 5,
1994.
(2) Within 90 days after April 29, 1996 (the effective date of
AD 96-07-06, Amendment 39-9555 (61 FR 14014, March 29, 1996)),
deactivate the FBTS in accordance with either Part 2 or Part 3, as
applicable, of the Accomplishment Instructions of Fokker Service
Bulletin SBF100-28-030, Revision 1, dated December 5, 1994.
Accomplishment of the deactivation constitutes terminating action
for the repetitive inspection requirements of paragraph (h)(1) of
this AD.
(i) New Requirements of This AD
Within 12 months after the effective date of this AD, modify the
airplane by installing an FBTV locking device, in accordance with
the Accomplishment Instructions of Fokker Service Bulletin SBF100-
28-066, dated June 30, 2011, which includes the attachments
