AGENCY: Federal Aviation
Administration (FAA), DOT.
ACTION: Final rule.
SUMMARY: We are adopting a new
airworthiness directive (AD) for certain
Model MD–11 and MD–11F airplanes.
This AD requires a one-time inspection
to determine if wires touch the upper
surface of the center upper auxiliary
fuel tank and marking the location, if
necessary; a one-time inspection of all
wire bundles above the center upper
auxiliary fuel tank for splices and
damage; a one-time inspection for
damage to the fuel vapor barrier seal
and upper surface of the center upper
auxiliary fuel tank; and corrective
actions, if necessary. This AD also
requires installation of nonmetallic
barrier/shield sleeving, new clamps,
new attaching hardware, and a new
extruded channel. This AD results from
fuel system reviews conducted by the
manufacturer. We are issuing this AD to
reduce the potential of ignition sources
inside fuel tanks, which, in combination
with flammable fuel vapors, could result

SUPPLEMENTARY INFORMATION:
Comments
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an airworthiness
directive (AD) that would apply to
certain McDonnell Douglas Corporation
Model MD–11 and MD–11F airplanes.
That NPRM was published in the
We gave the public the opportunity to
participate in developing this AD. We
considered the comments received from
the two commenters.
Request To Include Boeing Information
Notice MD11–28–126 IN 02 in the Final
Rule
FedEx requests that Boeing
Information Notice MD11–28–126 IN
02, dated July 1, 2009, be incorporated
into the final rule. FedEx states that
without including the information
notice, FedEx will not be able to comply
with the AD unless an Alternative
Method of Compliance (AMOC) is
granted. We partially agree. Boeing
issued Information Notice MD11–28–
126 IN 02 to clarify the group
applicability. The information notice is
not approved by the FAA; therefore, we
do not require the information notice for
accomplishment of work and it is not
incorporated into the requirements of
this final rule. Note 1 has been added to
this AD to explain that the information
notice provides clarification of the
airplane groups identified in the service
bulletin.
Request for Compliance Time Extension
KLM requests that we extend the
compliance time so that it will fall
during regularly scheduled maintenance
periods. KLM states that the 60-month
compliance time specified in the NPRM
does not take into consideration the
impact on operators of accessing the
area above the center upper auxiliary
fuel tank, which is only opened during
72-month intervals. KLM states the
work-hours and costs specified in the
NPRM are unrealistic because the
inspection is not done in the 72-month
period.
We do not agree with the commenter’s
request to extend the compliance time.
We have determined that the
compliance time, as proposed,
represents the maximum interval of
time allowable for the affected airplanes
to continue to safely operate before the
modification is done. Since
maintenance schedules vary among
operators, there would be no assurance
that the airplane would be modified
during that maximum interval.
However, operators may request an
AMOC in accordance with the
procedures specified in paragraph (j) of
this AD. We have not changed the AD
in this regard.
Explanation of Changes Made to This
AD
We have revised this AD to identify
the legal name of the manufacturer as
published in the most recent type
certificate data sheet for the affected
airplane models.
Conclusion
We reviewed the relevant data,
considered the comments received, and
determined that air safety and the
public interest require adopting the AD
with the changes described previously.
We also determined that these changes
will not increase the economic burden
on any operator or increase the scope of
the AD.
Costs of Compliance
We estimate that this AD affects 111
airplanes of U.S. registry. The following
table provides the estimated costs for
U.S. operators to comply with this AD.

Federal Register / Vol. 74, No. 250 / Thursday, December 31, 2009 / Rules and Regulations
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
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.

SUMMARY: The FAA is superseding an
existing airworthiness directive (AD) for
Lycoming Engines (formerly Textron
Lycoming) models 320, 360, and 540
series, ‘‘Parallel Valve’’ reciprocating
engines, with certain Engine
Components, Inc. (ECi) cylinder
assemblies, part number (P/N)
AEL65102 series ‘‘Titan,’’ installed.
That AD currently requires initial and
repetitive visual inspections and
compression tests to detect cracks at the
head-to-barrel interface, replacement of
cylinder assemblies found cracked, and
replacement of certain cylinder
assemblies at new, reduced times-inservice. This AD requires the same
actions, but for an expanded population
of cylinder assemblies. This AD results
from reports of 10 additional cylinder
head separations since issuing AD
2008–19–05, on cylinder serial numbers
not listed in that AD. We are issuing this
AD to prevent loss of engine power due
to cracks at the head-to-barrel interface
and possible engine failure caused by
separation of a cylinder head, which
could result in loss of control of the
aircraft.
DATES: This AD becomes effective
February 4, 2010.

SUPPLEMENTARY INFORMATION: The FAA
proposed to amend 14 CFR part 39 by
superseding AD 2008–19–05,
Amendment 39–15672 (73 FR 53105,
September 15, 2008), with a proposed
AD. The proposed AD applies to
Lycoming Engines (formerly Textron

series, ‘‘Parallel Valve’’ reciprocating
engines, with certain Engine
Components, Inc. (ECi) cylinder
assemblies, part number (P/N)
AEL65102 series ‘‘Titan,’’ installed. We
published the proposed AD in the
Federal Register on July 30, 2009 (74 FR

initial and repetitive visual inspections
and compression tests to detect cracks at
the head-to-barrel interface, replacement
of cylinder assemblies found cracked,
and replacement of certain cylinder
assemblies at new, reduced times-inservice, and for an expanded population

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 this AD, the regulatory
evaluation, any comments received, and
other information. The street address for
the Docket Operations office (telephone
(800) 647–5527) is provided in the
ADDRESSES section. Comments will be
available in the AD docket shortly after
receipt.
Comments
We provided the public the
opportunity to participate in the
development of this AD. We have
considered the comments received.
Two commenters state that proposed
AD paragraphs (m) and (n) are confusing
and contradictory. Paragraph (m) allows
repair or replacement of cylinders with
leakage provided that the cylinder is not
cracked, but paragraph (n) prohibits
removed cylinders from being reinstalled.
We agree. We changed paragraph (m)
to state ‘‘For Group ‘A’ cylinder
assemblies only, repair or replace the
engine cylinder assembly before further
flight if the cause of the low gauge
PO 00000
Frm 00010
Fmt 4700
Sfmt 4700
reading in paragraph (k) of this AD is
from leaking intake or exhaust valves, or
from leaking piston rings.’’ We also
changed paragraph (n) to state, ‘‘After
the effective date of this AD, do not
install any Group ‘B’ ECi cylinder
assembly, P/N AEL65102, onto any
engine and do not attempt to repair or
reuse Group ‘B’ cylinder assemblies.’’
Conclusion
We have carefully reviewed the
available data, including the comments
received, and determined that air safety
and the public interest require adopting
the AD with the changes described
previously. We have determined that
these changes will neither increase the
economic burden on any operator nor
increase the scope of the AD.
Costs of Compliance
We estimate that this AD will affect
about 18,000 ECi cylinder assemblies
installed in aircraft of U.S. registry. The
visual inspection and compression tests
will take about 4 work-hours for each
engine. An individual cylinder
replacement will require $1,100 for
parts and 6 work-hours. Lycoming
engines with a set of 4 ECi cylinders
will require 12 work-hours for the
cylinder replacement. Lycoming engines
with a set of 6 ECi cylinders will require
16 work-hours for the cylinder
replacement. We estimate 18 percent of
the affected population of cylinders will
be replaced. We estimate the total cost
of the AD to U.S. operators to be
$10,172,000. Our estimate is exclusive
of any possible warranty coverage.
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.

Airworthiness Directives; McDonnell Douglas Corporation Model MD-
11 and MD-11F Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Model MD-11 and MD-11F airplanes. This AD requires a one-time
inspection to determine if wires touch the upper surface of the center
upper auxiliary fuel tank and marking the location, if necessary; a
one-time inspection of all wire bundles above the center upper
auxiliary fuel tank for splices and damage; a one-time inspection for
damage to the fuel vapor barrier seal and upper surface of the center
upper auxiliary fuel tank; and corrective actions, if necessary. This
AD also requires installation of nonmetallic barrier/shield sleeving,
new clamps, new attaching hardware, and a new extruded channel. This AD
results from fuel system reviews conducted by the manufacturer. We are
issuing this AD to reduce the potential of ignition sources inside fuel
tanks, which, in combination with flammable fuel vapors, could result
[[Page 69250]]
in fuel tank explosions and consequent loss of the airplane.
DATES: This AD is effective February 4, 2010.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of February 4,
2010.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an airworthiness directive (AD) that would apply to
certain McDonnell Douglas Corporation Model MD-11 and MD-11F airplanes.
That NPRM was published in the Federal Register on August 19, 2009 (74
FR 41813). That NPRM proposed to require a one-time inspection to
determine if wires touch the upper surface of the center upper
auxiliary fuel tank and marking the location, if necessary; a one-time
inspection of all wire bundles above the center upper auxiliary fuel
tank for splices and damage; a one-time inspection for damage to the
fuel vapor barrier seal and upper surface of the center upper auxiliary
fuel tank; and corrective actions, if necessary. That NPRM also
proposed to require installation of nonmetallic barrier/shield
sleeving, new clamps, new attaching hardware, and a new extruded
channel.
Comments
We gave the public the opportunity to participate in developing
this AD. We considered the comments received from the two commenters.
Request To Include Boeing Information Notice MD11-28-126 IN 02 in the
Final Rule
FedEx requests that Boeing Information Notice MD11-28-126 IN 02,
dated July 1, 2009, be incorporated into the final rule. FedEx states
that without including the information notice, FedEx will not be able
to comply with the AD unless an Alternative Method of Compliance (AMOC)
is granted. We partially agree. Boeing issued Information Notice MD11-
28-126 IN 02 to clarify the group applicability. The information notice
is not approved by the FAA; therefore, we do not require the
information notice for accomplishment of work and it is not
incorporated into the requirements of this final rule. Note 1 has been
added to this AD to explain that the information notice provides
clarification of the airplane groups identified in the service
bulletin.
Request for Compliance Time Extension
KLM requests that we extend the compliance time so that it will
fall during regularly scheduled maintenance periods. KLM states that
the 60-month compliance time specified in the NPRM does not take into
consideration the impact on operators of accessing the area above the
center upper auxiliary fuel tank, which is only opened during 72-month
intervals. KLM states the work-hours and costs specified in the NPRM
are unrealistic because the inspection is not done in the 72-month
period.
We do not agree with the commenter's request to extend the
compliance time. We have determined that the compliance time, as
proposed, represents the maximum interval of time allowable for the
affected airplanes to continue to safely operate before the
modification is done. Since maintenance schedules vary among operators,
there would be no assurance that the airplane would be modified during
that maximum interval. However, operators may request an AMOC in
accordance with the procedures specified in paragraph (j) of this AD.
We have not changed the AD in this regard.
Explanation of Changes Made to This AD
We have revised this AD to identify the legal name of the
manufacturer as published in the most recent type certificate data
sheet for the affected airplane models.
Conclusion
We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
the AD with the changes described previously. We also determined that
these changes will not increase the economic burden on any operator or
increase the scope of the AD.
Costs of Compliance
We estimate that this AD affects 111 airplanes of U.S. registry.
The following table provides the estimated costs for U.S. operators to
comply with this AD.

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.
[[Page 69251]]
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
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.
You can find our regulatory evaluation and the estimated costs of
compliance in the AD Docket.
