AGENCY: Federal Aviation
Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
SUMMARY: We are adopting a new
airworthiness directive (AD) to
supersede AD 2008–12–16, which
applies to certain M7 Aerospace LP
SA226 and SA227 series airplanes. AD
2008–12–16 currently requires you to
inspect wires and tube assemblies for
chafing, arcing, or insufficient clearance
between components. If chafing, arcing,
or insufficient clearance between
components is found, AD 2008–12–16
requires you to clear, repair, and/or
replace all chafed wires, components,
and tube assemblies. AD 2008–12–16
also requires you to cover the four-gauge
wires leaving the battery box with
firesleeving and secure them with a
clamp. Since we issued AD 2008–12–16,
VerDate Nov<24>2008

Jkt 217001
M7 Aerospace LP has notified us that
Model SA227–BC (C–26A) was
inadvertently left out of the
Applicability section of the AD, and
they updated some of the service
information due to parts availability.
Operators have also identified issues
with model applicability that needed
clarification. Consequently, this AD
retains the actions of AD 2008–12–16,
adds Model SA227–BC (C–26A) to the
Applicability section, and regroups the
models for clarification. We are issuing
this AD to detect and correct chafing of
electrical wires, components, and tube
assemblies. This condition could result
in arcing of exposed wires with
consequent burning of a hole in a
hydraulic line or the bleed air line. This
failure could lead to a hydraulic fluid
leak and a possible fire in the engine
nacelle compartment.
DATES: This AD becomes effective on
July 2, 2009.
On July 2, 2009, the Director of the
Federal Register approved the
incorporation by reference of certain
publications listed in Table 2 of this AD.
As of July 23, 2008 (73 FR 34615, June
18, 2008), the Director of the Federal
Register approved the incorporation by
reference of certain publications listed
in Table 3 of this AD.

SUPPLEMENTARY INFORMATION:
certain M7 Aerospace LP SA226 and
SA227 series airplanes. This proposal
was published in the Federal Register
as a notice of proposed rulemaking
(NPRM) on February 12, 2009 (74 FR
7006). The NPRM proposed to
supersede AD 2008–12–16 with a new
AD that would retain the actions of AD
2008–12–16, add the Model SA227–BC
(C–26A) to the Applicability section,
and regroup the models for clarification.
Discussion
Costs of Compliance
On February 6, 2009, we issued a
proposal to amend part 39 of the Federal
Aviation Regulations (14 CFR part 39) to
include an AD that would apply to
We estimate that this AD affects 268
airplanes in the U.S. registry.
We estimate the following costs to do
the inspection:

Comments
We provided the public the
opportunity to participate in developing
this AD. The following presents the
comment received on the proposal and
FAA’s response:
Comment Issue: Inspection
Applicability
George L. Smith commented that it
was unclear if paragraph (e)(3) of the AD
applied to airplanes with batteries
mounted in the nose of the airplane or
if the AD only applied to airplanes with
the battery located in the wing leading
edge.
As specified in the Applicability
section, this AD applies to all serial
numbers regardless of where the battery
is located. Therefore the actions
required in paragraph (e)(3) of this AD
apply to all airplanes listed in the
Applicability section regardless of
where the battery is located. For added
clarity we are adding the applicable
serial numbers to the paragraph.
We are changing the final rule AD by
adding the applicable serial numbers to
each action based on this comment.
Conclusion
We have carefully reviewed the
available data and determined that air
safety and the public interest require
adopting the AD as proposed except for
the change previously discussed and
minor editorial corrections. We have
determined that these minor
corrections:
• Are consistent with the intent that
was proposed in the NPRM for
correcting the unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the NPRM.

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 AD.
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;

Adoption of the Amendment
Accordingly, under the authority
delegated to me by the Administrator,
the Federal Aviation Administration
amends part 39 of the Federal Aviation
Regulations (14 CFR part 39) as follows:
■
Regulatory Findings
VerDate Nov<24>2008
2. Is not a ‘‘significant rule’’ under the

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 summary of the costs
to comply with this AD (and other
information as included in the
Regulatory Evaluation) and placed it in
the AD Docket. You may get a copy of
this summary by sending a request to us

Unsafe Condition
(d) This AD results from five reports of
chafing between the bleed air tube assembly
and the electrical starter cables on M7
Aerospace LP SA226 and SA227 series
airplanes with one incident resulting in a
fire. We are issuing this AD to detect and
correct chafing of electrical wires and
components, hydraulic tube assemblies, and
bleed air tube assemblies. This condition
could result in arcing of the exposed wires
with consequent burning of a hole in a
hydraulic line or the bleed air line. This
failure could lead to a possible hydraulic

SUMMARY: We are adopting a new
airworthiness directive (AD) for
Eurocopter Deutschland GmbH
(Eurocopter) Model EC135 helicopters.
This AD results from a report of
abnormal main rotor blade vibrations on
a Eurocopter Model EC135 helicopter.
This AD also results from mandatory
continuing airworthiness information
(MCAI) issued by the European Aviation
Safety Agency (EASA), which is the
Technical Agent for the Member States
of the European Community. The MCAI
states that an operator reported unusual
vibrations during the start phase of the
main rotor blade on one helicopter. The
vibrations stopped after the application
of torque. Subsequent maintenance
personnel found that six of the eight

attachment screws of the lower hubshaft bearing support were loose. This
condition was discovered in two
additional helicopters. Loose screws in
the bearing support, if not detected and
corrected, could result in abnormal
main rotor blade vibrations and
subsequent damage to the main
transmission.
DATES: This AD becomes effective on
June 12, 2009.
The incorporation by reference of
certain publications is approved by the
Director of the Federal Register as of
June 12, 2009.

SUPPLEMENTARY INFORMATION:
Discussion
We recently received a report of
abnormal main rotor blade vibration on
PO 00000
Frm 00008
Fmt 4700
Sfmt 4700
a Eurocopter Model EC135 helicopter.
This main rotor blade vibration
occurred after initial aircraft start, while
operating at flat pitch, between 8.5 and
25 percent torque and 98.6 percent NR/
N2 speed, and dissipated once the
FADEC switches were advanced to
FLIGHT. The main rotor transmission
chip light also illuminated with
minimal debris found on the chip
detectors. During troubleshooting, six of
the eight main transmission lower hubshaft bearing support bolts were found
lying in the bottom of the main
transmission case, atop of the lower
transmission access panel. Only two of
the eight bolts remained installed, loose
in their positions, and the outer race of
the roller bearing was rotated out of
position (cocked). Approximately three
weeks after that first incident, we
received a report that loose bolts were
discovered on two additional newer
helicopters that had not been inspected
at the time the loose bolts were
discovered on the first helicopter.
Subsequent investigations revealed that
screws were not properly torqued and
vibrations had caused the screws to
back-out. Loosened screws in the
bearing support, if not detected and
corrected, could result in abnormal
main rotor blade vibrations and
subsequent damage to the main
transmission.
EASA has issued EASA Emergency
AD 2008–0175–E, dated September 16,
2008, to correct an unsafe condition for
the Eurocopter Model EC135
helicopters. The MCAI explains that
‘‘The lower hub-shaft bearing consists of
a ball bearing and a roller bearing. The
outer race of the roller bearing is fixed
to the housing with screws. Should all
attachment screws become loose, the
outer race of the roller bearing might
separate, which would constitute an
unsafe condition. In such case, however,
the axial guidance of the rotor hub-shaft
would still be ensured.’’ The MCAI
requires inspecting the main
transmission attachment hardware and
installing locking washers. You may
obtain further information by examining
the MCAI and any related service
information in the AD docket.
Related Service Information
Eurocopter has issued Alert Service
Bulletin EC135–63A–013, Revision 2,
dated September 12, 2008 (ASB). The
ASB specifies checking the screws at the
lower hub-shaft bearing for correct
attachment and securing attachment
hardware by means of locking washers.
The actions described in the MCAI are
intended to correct the same unsafe
condition as that identified in the
service information.

-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) to
supersede AD 2008-12-16, which applies to certain M7 Aerospace LP SA226
and SA227 series airplanes. AD 2008-12-16 currently requires you to
inspect wires and tube assemblies for chafing, arcing, or insufficient
clearance between components. If chafing, arcing, or insufficient
clearance between components is found, AD 2008-12-16 requires you to
clear, repair, and/or replace all chafed wires, components, and tube
assemblies. AD 2008-12-16 also requires you to cover the four-gauge
wires leaving the battery box with firesleeving and secure them with a
clamp. Since we issued AD 2008-12-16, M7 Aerospace LP has notified us
that Model SA227-BC (C-26A) was inadvertently left out of the
Applicability section of the AD, and they updated some of the service
information due to parts availability. Operators have also identified
issues with model applicability that needed clarification.
Consequently, this AD retains the actions of AD 2008-12-16, adds Model
SA227-BC (C-26A) to the Applicability section, and regroups the models
for clarification. We are issuing this AD to detect and correct chafing
of electrical wires, components, and tube assemblies. This condition
could result in arcing of exposed wires with consequent burning of a
hole in a hydraulic line or the bleed air line. This failure could lead
to a hydraulic fluid leak and a possible fire in the engine nacelle
compartment.
DATES: This AD becomes effective on July 2, 2009.
On July 2, 2009, the Director of the Federal Register approved the
incorporation by reference of certain publications listed in Table 2 of
this AD.
As of July 23, 2008 (73 FR 34615, June 18, 2008), the Director of
the Federal Register approved the incorporation by reference of certain
publications listed in Table 3 of this AD.

SUPPLEMENTARY INFORMATION:
Discussion
On February 6, 2009, we issued a proposal to amend part 39 of the
Federal Aviation Regulations (14 CFR part 39) to include an AD that
would apply to certain M7 Aerospace LP SA226 and SA227 series
airplanes. This proposal was published in the Federal Register as a
notice of proposed rulemaking (NPRM) on February 12, 2009 (74 FR 7006).
The NPRM proposed to supersede AD 2008-12-16 with a new AD that would
retain the actions of AD 2008-12-16, add the Model SA227-BC (C-26A) to
the Applicability section, and regroup the models for clarification.
Comments
We provided the public the opportunity to participate in developing
this AD. The following presents the comment received on the proposal
and FAA's response:
Comment Issue: Inspection Applicability
George L. Smith commented that it was unclear if paragraph (e)(3)
of the AD applied to airplanes with batteries mounted in the nose of
the airplane or if the AD only applied to airplanes with the battery
located in the wing leading edge.
As specified in the Applicability section, this AD applies to all
serial numbers regardless of where the battery is located. Therefore
the actions required in paragraph (e)(3) of this AD apply to all
airplanes listed in the Applicability section regardless of where the
battery is located. For added clarity we are adding the applicable
serial numbers to the paragraph.
We are changing the final rule AD by adding the applicable serial
numbers to each action based on this comment.
Conclusion
We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD as proposed
except for the change previously discussed and minor editorial
corrections. We have determined that these minor corrections:
Are consistent with the intent that was proposed in the
NPRM for correcting the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.
Costs of Compliance
We estimate that this AD affects 268 airplanes in the U.S.
registry.
We estimate the following costs to do the inspection:
[[Page 25391]]
----------------------------------------------------------------------------------------------------------------
Total cost per Total cost on
Labor cost Parts cost airplane U.S. operators
----------------------------------------------------------------------------------------------------------------
4 work-hours x $80 per hour = $320............ Not Applicable.................. $320 $85,760
----------------------------------------------------------------------------------------------------------------
We estimate the following costs to do any necessary modifications
for certain Models SA226-AT, SA226-T, SA226-TC, SA227-AC, and SA227-AT
airplanes referenced in M7 Aerospace SA226 Series Service Bulletin 226-
24-019, revised: November 21, 2008; or M7 Aerospace SA227 Series
Service Bulletin 227-24-001, revised: November 21, 2008. We estimate 88
airplanes may need this modification:
----------------------------------------------------------------------------------------------------------------
Total cost per Total cost on
Labor cost Parts cost airplane U.S. operators
----------------------------------------------------------------------------------------------------------------
13 work-hours x $80 per hour = $1,040........................... $7 $1,047 $92,136
----------------------------------------------------------------------------------------------------------------
We estimate the following costs to do any necessary repairs for
certain Models SA226-AT, SA226-TC, SA227-AC, and SA227-AT referenced in
M7 Aerospace SA226 Series Service Bulletin 226-24-020, revised: August
4, 2008; or M7 Aerospace SA227 Series Service Bulletin 227-24-002,
revised: November 21, 2008. We have no way of determining the number of
airplanes that may need this repair:
------------------------------------------------------------------------
Total cost per
Labor cost Parts cost airplane
------------------------------------------------------------------------
50 work-hours x $80 per hour = $4,000... $3,000 $7,000
------------------------------------------------------------------------
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 AD.
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 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 summary of the costs to comply with this AD (and
other information as included in the Regulatory Evaluation) and placed
it in the AD Docket. You may get a copy of this summary by sending a
request to us at the address listed under ADDRESSES. Include ``Docket
No. FAA-2009-0119; Directorate Identifier 2008-CE-068-AD'' in your
request.

(C-26B) airplanes, all serial numbers, that are certificated in any
category.
Unsafe Condition
(d) This AD results from five reports of chafing between the
bleed air tube assembly and the electrical starter cables on M7
Aerospace LP SA226 and SA227 series airplanes with one incident
resulting in a fire. We are issuing this AD to detect and correct
chafing of electrical wires and components, hydraulic tube
assemblies, and bleed air tube assemblies. This condition could
result in arcing of the exposed wires with consequent burning of a
hole in a hydraulic line or the bleed air line. This failure could
lead to a possible hydraulic fluid leak and fire in the engine
nacelle compartment.
