Federal Aviation
Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
AGENCY:
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:
SUMMARY:
When preparing for landing, the flight crew
of a F28 Mark 0100 (Fokker 100) aeroplane
observed a main landing gear (MLG) unsafe
indication after landing gear down selection.
* * * [T]he right (RH) MLG was partly
extended and the left (LH) MLG door was
open but without the MLG being extended.
* * *
Subsequent investigation revealed that the
cause of the MLG extension problem was the
(partially) blocked hydraulic return line from
the MLG selector valve by pieces of hard
plastic. These were identified as parts of the
poppet seat of PBSOV [parking brake shut-off
valve] Part Number (P/N) 70379. * * *
This condition, if not detected and
corrected, could lead to further events where
the MLG fails to extend, possibly resulting in
loss of control of the aeroplane during
landing.
*
*
*
*
*
We are issuing this AD to require
actions to correct the unsafe condition
on these products.
DATES: This AD becomes effective
December 3, 2010.
The Director of the Federal Register
approved the incorporation by reference
of certain publications listed in this AD
as of December 3, 2010.

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 May 18, 2010 (75 FR 27668).
That NPRM proposed to correct an
unsafe condition for the specified
products. The MCAI states:
When preparing for landing, the flight crew
of a F28 Mark 0100 (Fokker 100) aeroplane
observed a main landing gear (MLG) unsafe
indication after landing gear down selection.
The approach was aborted and the landing
gear unsafe procedure was accomplished. As
this did not produce the desired effect, a low
pass was performed and the control tower
confirmed that the right (RH) MLG was partly
extended and the left (LH) MLG door was
open but without the MLG being extended.
Eventually the aeroplane landed with partly
extended landing gear, without resulting in
serious injuries to the occupants.
Subsequent investigation revealed that the
cause of the MLG extension problem was the
(partially) blocked hydraulic return line from
the MLG selector valve by pieces of hard
plastic. These were identified as parts of the
poppet seat of PBSOV [parking brake shut-off
valve] Part Number (P/N) 70379. The PBSOV
installed on the incident aeroplane was a
modified version of P/N 70379, identified by
suffix ‘‘A’’ behind the serial number on the
identification plate. This modification was
introduced by Eaton, the valve manufacturer,
with Eaton Service Bulletin (SB) 70379–32–
01 and includes replacement of the original
poppet with clamped hard plastic seat by an
improved poppet assembly with screwed-on
seat. When the affected valve was opened, it
was confirmed that it contained the
improved poppet assembly. The poppet seat
fragments found in the return system
therefore originated from a previously
installed (pre SB 70379–32–01) P/N 70379
PBSOV and must have been present in the
return/pressure line prior to installation of
the modified PBSOV.
This condition, if not detected and
corrected, could lead to further events where
the MLG fails to extend, possibly resulting in
loss of control of the aeroplane during
landing.
For the reasons described above, this
[EASA] AD requires the [detailed] inspection
of the associated hydraulic lines, irrespective
what type PBSOV is installed, removal of
E:\FR\FM\29OCR1.SGM
29OCR1
66650
Federal Register / Vol. 75, No. 209 / Friday, October 29, 2010 / Rules and Regulations
contamination in the system, if any, and
replacement of each unmodified PBSOV with
a modified unit. This [EASA] AD also
prohibits, after installation of a modified
PBSOV on an aeroplane, re-installation of an
unmodified PBSOV on that aeroplane.
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 6
products of U.S. registry. We also
estimate that it will take about 4 workhours per product to comply with the
basic requirements of this AD. The
average labor rate is $85 per work-hour.
Based on these figures, we estimate the
cost of this AD to the U.S. operators to
be $2,040, or $340 per product.
WReier-Aviles on DSKGBLS3C1PROD with RULES
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
VerDate Mar<15>2010
13:56 Oct 28, 2010
Jkt 223001
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.

this did not produce the desired effect, a low pass was performed
and the control tower confirmed that the right (RH) MLG was partly
extended and the left (LH) MLG door was open but without the MLG
being extended. Eventually the aeroplane landed with partly extended
landing gear, without resulting in serious injuries to the
occupants.
Subsequent investigation revealed that the cause of the MLG
extension problem was the (partially) blocked hydraulic return line
from the MLG selector valve by pieces of hard plastic. These were
identified as parts of the poppet seat of PBSOV [parking brake shut-
off valve] Part Number (P/N) 70379. The PBSOV installed on the
incident aeroplane was a modified version of P/N 70379, identified
by suffix ``A'' behind the serial number on the identification
plate. This modification was introduced by Eaton, the valve
manufacturer, with Eaton Service Bulletin (SB) 70379-32-01 and
includes replacement of the original poppet with clamped hard
plastic seat by an improved poppet assembly with screwed-on seat.
When the affected valve was opened, it was confirmed that it
contained the improved poppet assembly. The poppet seat fragments
found in the return system therefore originated from a previously
installed (pre SB 70379-32-01) P/N 70379 PBSOV and must have been
present in the return/pressure line prior to installation of the
modified PBSOV.
This condition, if not detected and corrected, could lead to
further events where the MLG fails to extend, possibly resulting in
loss of control of the aeroplane during landing.
For the reasons described above, this [EASA] AD requires the
[detailed] inspection of the associated hydraulic lines,
irrespective what type PBSOV is installed, removal of
[[Page 66650]]
contamination in the system, if any, and replacement of each
unmodified PBSOV with a modified unit. This [EASA] AD also
prohibits, after installation of a modified PBSOV on an aeroplane,
re-installation of an unmodified PBSOV on that aeroplane.
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 6 products of U.S. registry.
We also estimate that it will take about 4 work-hours per product to
comply with the basic requirements of this AD. The average labor rate
is $85 per work-hour. Based on these figures, we estimate the cost of
this AD to the U.S. operators to be $2,040, or $340 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.

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:
2010-22-05 Fokker Services B.V.: Amendment 39-16484. Docket No. FAA-
2010-0516; Directorate Identifier 2009-NM-251-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective December
3, 2010.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Fokker Services B.V. Model F.28 Mark 0070
and 0100 airplanes, certificated in any category, all serial

MLG was partly extended and the left (LH) MLG door was open but
without the MLG being extended. * * *
Subsequent investigation revealed that the cause of the MLG
extension problem was the (partially) blocked hydraulic return line
from the MLG selector valve by pieces of hard plastic. These were
identified as parts of the poppet seat of PBSOV [parking brake shut-
off valve] Part Number (P/N) 70379. * * *
This condition, if not detected and corrected, could lead to
further events where the MLG fails to extend, possibly resulting in
loss of control of the aeroplane during landing.
* * * * *
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.
Actions
