AGENCY:
SUMMARY: The FAA is superseding an
existing airworthiness directive (AD),
which applies to certain Fokker Model
F.28 Mark 0070 and 0100 airplanes.
That AD currently requires a one-time
inspection of the sliding members in the
main landing gear (MLG) for cracking
and replacement of the sliding members
with serviceable parts if necessary. This
new AD adds repetitive magnetic
particle inspections of the sliding
members of the MLG for cracking and

corrective actions as necessary. This AD
results from inspection findings that
have shown repetitive inspections are
needed to establish fleet safety. We are
issuing this AD to detect and correct
fatigue cracking of the sliding member,
which could result in possible
separation of the MLG from the airplane
and consequent reduced controllability
of the airplane upon landing and
possible injury to passengers.
DATES: This AD becomes effective April
3, 2007.
The Director of the Federal Register
approved the incorporation by reference
of certain publications listed in the AD
as of April 3, 2007.
On May 19, 2004 (69 FR 19759, April
14, 2004), the Director of the Federal
Register approved the incorporation by
reference of Fokker Service Bulletin

Discussion
The FAA issued a supplemental
notice of proposed rulemaking (NPRM)
to amend 14 CFR part 39 to include an
AD that supersedes AD 2004–08–01,
amendment 39–13570 (69 FR 19759,
April 14, 2004). The existing AD applies
to certain Fokker Model F.28 Mark 0070
and 0100 airplanes. That supplemental
NPRM was published in the Federal
Register on December 28, 2006 (71 FR
78107). That supplemental NPRM
E:\FR\FM\27FER1.SGM
27FER1
8616
Federal Register / Vol. 72, No. 38 / Tuesday, February 27, 2007 / Rules and Regulations
proposed to continue to require a onetime inspection of the sliding members
in the main landing gear (MLG) for
cracking, and replacement of the sliding
members with serviceable parts if
necessary. That supplemental NPRM
also proposed to require repetitive
magnetic particle inspections of the
sliding members of the MLG for
cracking and corrective actions as
necessary. That supplemental NPRM
also revised the original NPRM by
correcting a certain part number in the
applicability.
Comments
We provided the public the
opportunity to participate in the
development of this AD. No comments
have been received on the supplemental
NPRM or on the determination of the
cost to the public.
Conclusion
We have carefully reviewed the
available data and determined that air
safety and the public interest require
adopting the AD as proposed by the
supplemental NPRM.
Costs of Compliance
This AD affects about 37 airplanes of
U.S. registry.
The inspection that is required by AD
2004–08–01 and retained in this AD
takes either about 4 or 12 work hours
per airplane, depending on airplane
configuration, at an average labor rate of
$80 per work hour. Based on these
figures, the estimated cost of the
currently required actions for U.S.
operators is $11,840 or $35,520, or $320
or $960 per airplane, depending on
airplane configuration.
The new required inspections take
about 2 work hours per airplane, at an
average labor rate of $80 per work hour.
Based on these figures, the estimated
cost of the new inspections specified in
this AD for U.S. operators is $5,920, or
$160 per airplane, per inspection cycle.
cprice-sewell on PROD1PC66 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
for practices, methods, and procedures
VerDate Aug<31>2005
14:03 Feb 26, 2007
Jkt 211001
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 have 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
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.
See the ADDRESSES section for a location
to examine the regulatory evaluation.

SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for all
Fokker Model F.28 Mark 0070 and 0100
airplanes. This AD requires a one-time
inspection of the fuel lines located in
the left and right main landing gear

inspection of fuel lines for chafing, the
replacement of a chafed fuel line with
a new fuel line, and the repositioning of
existing clamps and installation of
additional clamps between the fuel and
hydraulic lines. This AD results from a
fuel leak found in the left MLG bay. We
are issuing this AD to detect and correct
inadequate clearance between fuel and
hydraulic lines in the MLG bay, which
could lead to chafing of a fuel line and
fuel leakage. A fuel leak near hot brakes
could result in a fire in the MLG bay.
DATES: This AD becomes effective April
3, 2007.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in the AD
as of April 3, 2007.

SUPPLEMENTARY INFORMATION:
Examining the Docket
You may examine the airworthiness directive (AD) docket on the
Internet at https://dms.dot.gov or in person at the Docket Management
Facility office between 9 a.m. and 5 p.m., Monday through Friday,
except Federal holidays. The Docket Management Facility office
(telephone (800) 647-5227) is located on the plaza level of the Nassif
Building at the street address stated in the ADDRESSES section.
Discussion
The FAA issued a supplemental notice of proposed rulemaking (NPRM)
to amend 14 CFR part 39 to include an AD that supersedes AD 2004-08-01,
amendment 39-13570 (69 FR 19759, April 14, 2004). The existing AD
applies to certain Fokker Model F.28 Mark 0070 and 0100 airplanes. That
supplemental NPRM was published in the Federal Register on December 28,
2006 (71 FR 78107). That supplemental NPRM
[[Page 8616]]
proposed to continue to require a one-time inspection of the sliding
members in the main landing gear (MLG) for cracking, and replacement of
the sliding members with serviceable parts if necessary. That
supplemental NPRM also proposed to require repetitive magnetic particle
inspections of the sliding members of the MLG for cracking and
corrective actions as necessary. That supplemental NPRM also revised
the original NPRM by correcting a certain part number in the
applicability.
Comments
We provided the public the opportunity to participate in the
development of this AD. No comments have been received on the
supplemental NPRM or on the determination of the cost to the public.
Conclusion
We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD as proposed
by the supplemental NPRM.
Costs of Compliance
This AD affects about 37 airplanes of U.S. registry.
The inspection that is required by AD 2004-08-01 and retained in
this AD takes either about 4 or 12 work hours per airplane, depending
on airplane configuration, at an average labor rate of $80 per work
hour. Based on these figures, the estimated cost of the currently
required actions for U.S. operators is $11,840 or $35,520, or $320 or
$960 per airplane, depending on airplane configuration.
The new required inspections take about 2 work hours per airplane,
at an average labor rate of $80 per work hour. Based on these figures,
the estimated cost of the new inspections specified in this AD for U.S.
operators is $5,920, or $160 per airplane, per inspection cycle.
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 have 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 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. See the ADDRESSES
section for a location to examine the regulatory evaluation.

Adoption of the Amendment
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 Federal Aviation Administration (FAA) amends Sec. 39.13 by
removing amendment 39-13570 (69 FR 19759, April 14, 2004) and by adding
the following new airworthiness directive (AD):
2007-04-23 Fokker Services B.V.: Amendment 39-14956. Docket No. FAA-
2006-25391; Directorate Identifier 2006-NM-097-AD.
Effective Date
(a) This AD becomes effective April 3, 2007.
Affected ADs
(b) This AD supersedes AD 2004-08-01.
Applicability
(c) This AD applies to Fokker Model F.28 Mark 0070 and 0100
airplanes, certificated in any category; equipped with any Dowty or
Messier-Dowty main landing gear (MLG) listed in Table 1 of this AD.

Unsafe Condition
(d) This AD results from inspection findings that have shown
repetitive inspections are needed to establish fleet safety. We are
issuing this AD to detect and correct fatigue cracking of the
sliding member, which could result in possible separation of the MLG
from the airplane and consequent reduced controllability of the
airplane upon landing and possible injury to passengers.
