[Docket No. FAA-2006-25739; Directorate Identifier 2006-CE-46-AD]
RIN 2120-AA64
Airworthiness Directives; Raytheon Aircraft Company Models 58 and
G58 Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
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.
[[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 http://dms.dot.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) 647-5227)
is located at the street address stated in the ADDRESSES section.
Comments will be available in the AD docket shortly after receipt.
