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 proposed AD would
retain the actions of AD 2008–12–16,
add Model SA227–BC (C–26A) to the
Applicability section, and regroup the
models for clarification. We are
proposing 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.

this proposed AD by April 13, 2009.

Discussion
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, caused us to issue AD 2008–12–
16, Amendment 39–15560 (73 FR
34615, June 18, 2008). AD 2008–12–16
currently requires the following on M7
Aerospace LP SA226 and SA227 series
airplanes:
• Inspect electrical wires and
components, hydraulic tube assemblies,
and bleed air tube assemblies, for
sufficient clearance between
components or any evidence of chafing
or arcing;
E:\FR\FM\12FEP1.SGM
12FEP1
7007
Federal Register / Vol. 74, No. 28 / Thursday, February 12, 2009 / Proposed Rules
• Clear, repair, and/or replace all
chafed electrical wires and components,
chafed hydraulic tube assemblies, and
chafed bleed air tube assemblies; and
• 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 the model
applicability that needed clarification.
Consequently, this proposed AD 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. We are
proposing this AD to detect and correct
chafing of electrical wires, components,
and 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 hydraulic fluid leak and a
possible fire in the engine nacelle
compartment.

Examining the AD Docket
Comments Due Date
You may examine the AD docket that
contains the proposed AD, the
regulatory evaluation, any comments
received, and other information on the
Internet at https://www.regulations.gov;
or in person at the Docket Management
Facility between 9 a.m. and 5 p.m.,

holidays. The Docket Office (telephone
(800) 647–5527) is located at the street
address stated in the ADDRESSES section.
Comments will be available in the AD
docket shortly after receipt.
(a) We must receive comments on this
airworthiness directive (AD) action by April
13, 2009.
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.
mstockstill on PROD1PC66 with PROPOSALS
Regulatory Findings
We have determined that this
proposed AD would not have federalism
implications under Executive Order
13132. This proposed AD would 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 the proposed regulation:
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

The Proposed Amendment
Accordingly, under the authority
delegated to me by the Administrator,
the FAA proposes to amend 14 CFR part
39 as follows:
PART 39—AIRWORTHINESS

2. The FAA amends § 39.13 by
removing Airworthiness Directive (AD)
2008–12–16, Amendment 39–15560 (73
FR 34615, June 18, 2008), and adding
the following new AD:
M7 Aerospace LP: Docket No. FAA–2009–
0119; Directorate Identifier 2008–CE–
068–AD.
Affected ADs
(b) This AD supersedes AD 2008–12–16,
Amendment 39–15560.
Applicability
(c) This AD applies to Models SA226–AT,
SA226–T, SA226–TC, SA227–AC (C–26A),
SA227–AT, SA227–BC (C–26A), SA227–CC,
and SA227–DC (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 proposing 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.
Compliance

Transportation (DOT).
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to supersede Airworthiness Directive (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 proposed AD
would retain the actions of AD 2008-12-16, add Model SA227-BC (C-26A)
to the Applicability section, and regroup the models for clarification.
We are proposing 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: We must receive comments on this proposed AD by April 13, 2009.
ADDRESSES: Use one of the following addresses to comment on this
proposed AD:

Discussion
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, caused us to issue AD
2008-12-16, Amendment 39-15560 (73 FR 34615, June 18, 2008). AD 2008-
12-16 currently requires the following on M7 Aerospace LP SA226 and
SA227 series airplanes:
Inspect electrical wires and components, hydraulic tube
assemblies, and bleed air tube assemblies, for sufficient clearance
between components or any evidence of chafing or arcing;
[[Page 7007]]
Clear, repair, and/or replace all chafed electrical wires
and components, chafed hydraulic tube assemblies, and chafed bleed air
tube assemblies; and
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 the
model applicability that needed clarification. Consequently, this
proposed AD 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. We are proposing this AD to detect and correct
chafing of electrical wires, components, and 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 hydraulic fluid leak and a possible fire
in the engine nacelle compartment.

FAA's Determination and Requirements of the Proposed AD
We are proposing this AD because we evaluated all information and
determined the unsafe condition described previously is likely to exist
or develop on other products of the same type design. This proposed AD
would supersede AD 2008-12-16 with a new AD that would retain the
actions of AD 2008-12-16, add Model SA227-BC (C26A) to the
Applicability section, and regroup the models for clarification. We are
proposing this AD to detect and correct chafing of electrical wires,
components, and tube assemblies. This proposed AD would require you to
use the service information described previously to perform these
actions.
Costs of Compliance
We estimate that this proposed AD would affect 268 airplanes in the
U.S. registry.
We estimate the following costs to do the proposed inspection:
----------------------------------------------------------------------------------------------------------------
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,

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 proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 the proposed
regulation:
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 proposed AD and placed it in the AD docket.
Examining the AD Docket
You may examine the AD docket that contains the proposed AD, the
regulatory evaluation, any comments received, and other information on
the Internet at https://www.regulations.gov; or in person at the Docket
Management Facility between 9 a.m. and 5 p.m., Monday through Friday,
except Federal holidays. The Docket Office (telephone (800) 647-5527)
is located at the street address stated in the ADDRESSES section.
Comments will be available in the AD docket shortly after receipt.

The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
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]
2. The FAA amends Sec. 39.13 by removing Airworthiness Directive
(AD) 2008-12-16, Amendment 39-15560 (73 FR 34615, June 18, 2008), and
adding the following new AD:
M7 Aerospace LP: Docket No. FAA-2009-0119; Directorate Identifier
2008-CE-068-AD.
Comments Due Date
(a) We must receive comments on this airworthiness directive
(AD) action by April 13, 2009.
Affected ADs
(b) This AD supersedes AD 2008-12-16, Amendment 39-15560.
Applicability
(c) This AD applies to Models SA226-AT, SA226-T, SA226-TC,
SA227-AC (C-26A), SA227-AT, SA227-BC (C-26A), SA227-CC, and SA227-DC
(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 proposing 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.
