AGENCY:
SUMMARY: We propose to adopt a new
airworthiness directive (AD) for certain
Raytheon Aircraft Company (RAC)
Models 58 and G58 airplanes with
optional propeller unfeathering
accumulators installed. This proposed
AD would require you to inspect the left
propeller accumulator oil tube assembly
for any chafing; replace the propeller
accumulator oil tube assembly if any
chafing is found; and reposition and
secure with clamps both the left engine
manifold pressure hose and its metal
identification tags to avoid contact with
other tubes, hoses, electrical wires,
parts, components, and structure. This
proposed AD results from several
reports on the affected airplanes of
chafing damage on the left propeller
accumulator oil tube assembly. This
includes an in-flight oil leak from the
left engine on an RAC Model G58
airplane. We are proposing this AD to
detect, correct, and prevent any chafing
damage of the left propeller accumulator
oil tube assembly, which could result in
loss of engine oil. Loss of engine oil may
lead to fire or smoke in the engine
compartment, inability to unfeather the
propeller, engine damage, or loss of
engine power.
DATES: We must receive comments on
this proposed AD by December 18,
2006.

Discussion
We received several reports of chafing
damage to the propeller accumulator oil

tube assembly on RAC Models 58 and
G58 airplanes. The damage occurs when
the left engine manifold pressure hose
and its metal identification tags rubs
against the tube assembly. Included in
these reports was an in-flight oil leak on
an RAC Model G58 airplane.
´
The RAC issued Safety Communique
No. 271, dated May 2006, that
recommended an inspection for possible
chafing between the left engine
manifold pressure hose and its metal
identification tags and the left propeller
accumulator oil tube assembly.
This condition, if not corrected, could
result in loss of engine oil. Loss of
engine oil may lead to fire or smoke in
the engine compartment, inability to
unfeather the propeller, engine damage,
or loss of engine power.
Relevant Service Information
We have reviewed RAC Mandatory
Service Bulletin No. SB 61–3806,
issued: August 2006.
The service information describes
procedures for:
• Inspecting the left engine manifold
pressure hose and its metal
identification tags for proper clearance
to avoid any chafing with the propeller
accumulator oil tube assembly;
• Inspecting the left propeller
accumulator oil tube assembly for
chafing damage and replacing if any
chafing damage is found; and
• Relocating and securing with
clamps the manifold pressure hose and
its metal identification tags to ensure
clearance between it and all tubes,
hoses, electrical wires, parts,
components, and structure.
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
require you to inspect the left propeller
accumulator oil tube assembly for any
chafing; replace the propeller
accumulator oil tube assembly if any
chafing is found; and reposition and
secure with clamps the left manifold
pressure hose and its metal
identification tags to ensure clearance
between it and all tubes, hoses,
electrical wires, parts, components, and
structure.

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:
VerDate Aug<31>2005
06:09 Oct 17, 2006
Jkt 211001
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://dms.dot.gov; or in

the proposed AD, we have determined
that no unsafe condition exists with
respect to the STC installed energy
attenuating wire. Accordingly, the
proposed AD is withdrawn.

STC No. SH8435SW or SH8419SW.
That NPRM was published in the
Federal Register on October 28, 2005
(70 FR 62085). The NPRM would have
required replacing energy attenuating
wire manufactured or invoiced during a
specified time frame. The NPRM
resulted from the disclosure that certain
energy attenuating wire may not have
the yield strength necessary to allow
seats to attenuate energy during an
emergency landing. The proposed
actions were intended to prevent failure
of a seat to attenuate energy during an
emergency landing and resulting in
injury to an occupant.
Actions Since NPRM Was Issued
Since issuing the NPRM, we have
determined that the seat with the
affected energy attenuating wire will
support the occupant adequately during
an emergency landing and therefore no
unsafe condition exists for Bell Model
206B helicopters modified with the two
STCs.
FAA’s Conclusions
Upon further consideration, we have
determined that the actions proposed in
the NPRM are not needed for Bell Model
206B helicopters. Accordingly, the
NPRM is withdrawn.
Withdrawal of the NPRM does not
preclude the FAA from issuing another
related action or commit the FAA to any
course of action in the future.
Regulatory Impact
Since this action only withdraws an
NPRM, it is neither a proposed nor a
final rule and therefore is not covered
under Executive Order 12866, the
Regulatory Flexibility Act, or DOT
Regulatory Policies and Procedures (44
FR 11034, February 26, 1979).

Discussion
We received several reports of chafing damage to the propeller
accumulator oil tube assembly on RAC Models 58 and G58 airplanes. The
damage occurs when the left engine manifold pressure hose and its metal
identification tags rubs against the tube assembly. Included in these
reports was an in-flight oil leak on an RAC Model G58 airplane.
The RAC issued Safety Communique No. 271, dated May 2006, that
recommended an inspection for possible chafing between the left engine
manifold pressure hose and its metal identification tags and the left
propeller accumulator oil tube assembly.
This condition, if not corrected, could result in loss of engine
oil. Loss of engine oil may lead to fire or smoke in the engine
compartment, inability to unfeather the propeller, engine damage, or
loss of engine power.
Relevant Service Information
We have reviewed RAC Mandatory Service Bulletin No. SB 61-3806,
issued: August 2006.
The service information describes procedures for:
Inspecting the left engine manifold pressure hose and its
metal identification tags for proper clearance to avoid any chafing
with the propeller accumulator oil tube assembly;
Inspecting the left propeller accumulator oil tube
assembly for chafing damage and replacing if any chafing damage is
found; and
Relocating and securing with clamps the manifold pressure
hose and its metal identification tags to ensure clearance between it
and all tubes, hoses, electrical wires, parts, components, and
structure.
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 require you to inspect the left propeller accumulator oil tube
assembly for any chafing; replace the propeller accumulator oil tube
assembly if any chafing is found; and reposition and secure with clamps
the left manifold pressure hose and its metal identification tags to
ensure clearance between it and all tubes, hoses, electrical wires,
parts, components, and structure.
[[Page 60925]]
Costs of Compliance
We estimate that this proposed AD would affect 49 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
----------------------------------------------------------------------------------------------------------------
1 work-hour x $80 per hour = $80........... N/A.......................... $119 $5,831
----------------------------------------------------------------------------------------------------------------
We estimate the following costs to do any necessary replacements
that would be required based on the results of the proposed inspection.
We have no way of determining the number of airplanes that may need
this replacement:
------------------------------------------------------------------------
Total cost per
Labor cost Parts cost airplane
------------------------------------------------------------------------
1 work-hour x $80 per hour = $80.......... $39 $119
------------------------------------------------------------------------
RAC will provide warranty credit as specified in RAC Mandatory
Service Bulletin No. SB 61-3806, issued: August 2006.
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://dms.dot.gov; or in person at the Docket
