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
(MLG) bays to determine the clearance
between the fuel and hydraulic lines. If
necessary, this AD also requires an
PO 00000

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.

Discussion
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would
apply to all Fokker Model F.28 Mark
0070 and 0100 airplanes. That NPRM
was published in the Federal Register
on November 20, 2006 (71 FR 67077).
That NPRM proposed to require a onetime inspection of the fuel lines located
in the left and right main landing gear
bays to determine the clearance between
the fuel and hydraulic lines. If
necessary, that NPRM proposed to
require an 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.
Comments
We provided the public the
opportunity to participate in the
development of this AD. We received no
comments on the 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.
cprice-sewell on PROD1PC66 with RULES
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
Jkt 211001
Accordingly, under the authority
delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as
follows:
I
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.

Adoption of the Amendment
Costs of Compliance
This AD affects about 9 airplanes of
U.S. registry. The required inspection
takes about 1 work hour per airplane, at
an average labor rate of $80 per work
hour. Based on these figures, the
estimated cost of this AD for U.S.
operators is $720, or $80 per airplane.
VerDate Aug<31>2005
(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.

bulletin.
Note 1: For the purposes of this AD, a
general visual inspection is: ‘‘A visual
examination of an interior or exterior area,
installation, or assembly to detect obvious
damage, failure, or irregularity. This level of
inspection is made from within touching
distance unless otherwise specified. A mirror
may be necessary to ensure visual access to
all surfaces in the inspection area. This level
of inspection is made under normally
available lighting conditions such as
daylight, hangar lighting, flashlight, or
droplight and may require removal or
opening of access panels or doors. Stands,
ladders, or platforms may be required to gain
proximity to the area being checked.’’
Corrective Actions
(g) If the fuel line is found chafed during
the inspection for chafing specified in
paragraph (f) of this AD, before further flight
after that inspection, do the actions in
paragraphs (g)(1) and (g)(2) of this AD. If the
fuel line is not found chafed, within 6
months after the inspection for chafing, do
the actions in paragraph (g)(2) of this AD.
(1) Replace the chafed fuel line with a new

SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for certain
Bombardier Model DHC–8–100 (as
described above), DHC–8–200, and
DHC–8–300 series airplanes. This AD
requires doing a one-time inspection for
damage of the electrical cable harness
assembly located on the left and right
wing root-to-fuselage aft seal, and repair
if necessary; and reworking the fuselage
aft seal assembly (left and right) to
create a clearance between the electrical
cable assemblies and the edge of the
fairing panel. This AD results from a
report that an airplane encountered an
uncommanded propeller feathering
during climb, which resulted in an
emergency landing. We are issuing this
AD to prevent chafing or grounding of
the wiring against the aft seal
assemblies, which, if not corrected,
could interrupt the operation of various
systems, including the propeller feather
control, alternating current (AC)
electrical power, and standby hydraulic

Conclusion
We have carefully reviewed the
available data and determined that air
safety and the public interest require
adopting the AD as proposed.
Costs of Compliance
This AD affects about 136 airplanes of
U.S. registry. The required actions take
about 4 work hours per airplane, at an
average labor rate of $80 per work hour.
Required parts cost about $75 per
airplane. Based on these figures, the
estimated cost of this AD for U.S.
operators is $53,720, or $395 per
airplane.
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.

of this AD for U.S. operators is $720, or $80 per airplane.
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
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 Federal Aviation Administration (FAA) amends Sec. 39.13 by
adding the following new airworthiness directive (AD):
2007-04-21 Fokker Services B.V.: Amendment 39-14953. Docket No. FAA-
2006-26355; Directorate Identifier 2006-NM-198-AD.
Effective Date
(a) This AD becomes effective April 3, 2007.
Affected ADs
(b) None.
Applicability
(c) This AD applies to all Fokker Model F.28 Mark 0070 and 0100
airplanes, certificated in any category.
Unsafe Condition
(d) This AD results from a fuel leak found in the left main
landing gear (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.
Compliance
(e) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Inspections for Clearance and Chafing
(f) Within 6 months after the effective date of this AD, do a
general visual inspection of the fuel lines located in the left and
right MLG bays to determine the clearance between the fuel and
hydraulic lines, in accordance with Part 1 of the Accomplishment
Instructions of Fokker Service Bulletin SBF100-28-041, dated July
20, 2005. If the clearance of a fuel line is 3 mm (millimeters) or
more, no further action is required by this AD for that fuel line
only. If the clearance of a fuel line is less than 3 mm, before
further flight, do a general visual inspection of the fuel line for
chafing in accordance with Part 1 of the Accomplishment Instructions
of the service bulletin.
Note 1: For the purposes of this AD, a general visual inspection
is: ``A visual examination of an interior or exterior area,
installation, or assembly to detect obvious damage, failure, or
irregularity. This level of inspection is made from within touching
distance unless otherwise specified. A mirror may be necessary to
ensure visual access to all surfaces in the inspection area. This
level of inspection is made under normally available lighting
conditions such as daylight, hangar lighting, flashlight, or
droplight and may require removal or opening of access panels or
doors. Stands, ladders, or platforms may be required to gain
proximity to the area being checked.''
Corrective Actions
(g) If the fuel line is found chafed during the inspection for
chafing specified in paragraph (f) of this AD, before further flight
after that inspection, do the actions in paragraphs (g)(1) and
(g)(2) of this AD. If the fuel line is not found chafed, within 6
months after the inspection for chafing, do the actions in paragraph
(g)(2) of this AD.
(1) Replace the chafed fuel line with a new fuel line in
accordance with Part 1 of the Accomplishment Instructions of Fokker
Service Bulletin SBF100-28-041, dated July 20, 2005.
(2) Reposition the existing clamps and install additional clamps
to obtain a minimum clearance of 3 mm between the fuel and hydraulic
lines, as applicable, in accordance with Part 2 of the
Accomplishment Instructions of Fokker Service Bulletin SBF100-28-
041, dated July 20, 2005.
Alternative Methods of Compliance (AMOCs)
(h)(1) The Manager, International Branch, ANM-116, Transport
Airplane Directorate, FAA, has the authority to approve AMOCs for
this AD, if requested in accordance with the procedures found in 14
CFR 39.19.
(2) Before using any AMOC approved in accordance with Sec.
39.19 on any airplane to which the AMOC applies, notify the
appropriate principal inspector in the FAA Flight Standards
Certificate Holding District Office.
