Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
We propose to adopt a new
airworthiness directive (AD) for Bell
Model 204B helicopters. This proposed
AD would require inspecting the tail
rotor (T/R) cable assembly for an
incorrectly machined body. This
proposed AD is prompted by a report
from Bell that a defective body on the
cable prevents the barrel assembly from
fully engaging in the body cavity. The
proposed actions are intended to
prevent disengagement of the cable from
the barrel, failure of the T/R pitch
control, and subsequent loss of control
of the helicopter.
DATES: We must receive comments on
this proposed AD by October 21, 2013.
ADDRESSES: You may send comments by

We received a report from Bell that a
number of cable assemblies, part
number (P/N) 205–001–720–001, were
manufactured with a defective body, P/
N 205–001–742–001. Bell states the
bodies were incorrectly machined with
a ‘‘false cut,’’ preventing the barrel
assembly, P/N 0301245, from fully
engaging with the body cavity. This
condition, combined with a failure of
the lockwire securing the barrel and the
cable, could result in disengagement of
the cable, T/R pitch control failure in a
fixed position, and subsequent loss of
control of the helicopter.
FAA’s Determination
We are proposing this AD because we
evaluated all known relevant
information and determined that an
unsafe condition exists and is likely to
exist or develop on other helicopters of
the same type design.
Related Service Information
We reviewed Bell Alert Service
Bulletin (ASB) No. 204B–12–68, dated
October 10, 2012, which describes
procedures for inspecting the barrel
assembly to determine if an incorrectly
machined body is installed. If an
incorrectly machined body is installed,
the ASB specifies replacing the cable
assembly. The ASB further specifies
inspecting the barrel assembly and cable
connection daily until the cable
assembly is replaced.
Proposed AD Requirements
This proposed AD would require
inspecting each cable assembly, within
25 hours time-in-service (TIS), to
determine if an incorrectly machined
body is installed. If an incorrectly
machined body is installed, the
proposed AD would require replacing
the cable assembly within 100 hours
TIS. Until the cable assembly is
replaced, this proposed AD would
require inspecting the assembly for
separation daily.

20AUP1
Federal Register / Vol. 78, No. 161 / Tuesday, August 20, 2013 / Proposed Rules
Differences Between This Proposed AD
and the Service Information
The ASB specifies replacing any
defective cable assembly within 100
hours TIS or by January 31, 2013; the
proposed AD specifies replacing the
cable assembly within 100 hours TIS.
Costs of Compliance
We estimate that this proposed AD
would affect 9 helicopters of U.S.
Registry. We estimate that operators
may incur the following costs in order
to comply with this AD. At an average
labor rate of $85 per hour, inspecting
the barrel assembly would require about
1 work-hour, for a cost per helicopter of
$85 and a total cost of $765 for the fleet.
If required, replacing a defective cable
assembly would require about 8 workhours, and required parts would cost
about $625, for a cost per helicopter of
$1,305.
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.
sroberts on DSK5SPTVN1PROD with PROPOSALS
Regulatory Findings
We 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, I certify
this 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);
VerDate Mar<15>2010
17:51 Aug 19, 2013

3. Will not affect intrastate aviation in
Alaska to the extent that it justifies
making a regulatory distinction; and
4. 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 an economic evaluation
of the estimated costs to comply with
this proposed AD and placed it in the
AD docket.

Discussion
We received a report from Bell that a number of cable assemblies,
part number (P/N) 205-001-720-001, were manufactured with a defective
body, P/N 205-001-742-001. Bell states the bodies were incorrectly
machined with a ``false cut,'' preventing the barrel assembly, P/N
0301245, from fully engaging with the body cavity. This condition,
combined with a failure of the lockwire securing the barrel and the
cable, could result in disengagement of the cable, T/R pitch control
failure in a fixed position, and subsequent loss of control of the
helicopter.
FAA's Determination
We are proposing this AD because we evaluated all known relevant
information and determined that an unsafe condition exists and is

assembly to determine if an incorrectly machined body is installed. If
an incorrectly machined body is installed, the ASB specifies replacing
the cable assembly. The ASB further specifies inspecting the barrel

Proposed AD Requirements
This proposed AD would require inspecting each cable assembly,
within 25 hours time-in-service (TIS), to determine if an incorrectly

installed, the proposed AD would require replacing the cable assembly
within 100 hours TIS. Until the cable assembly is replaced, this
proposed AD would require inspecting the assembly for separation daily.
[[Page 51127]]
Differences Between This Proposed AD and the Service Information
The ASB specifies replacing any defective cable assembly within 100
hours TIS or by January 31, 2013; the proposed AD specifies replacing
the cable assembly within 100 hours TIS.
Costs of Compliance
We estimate that this proposed AD would affect 9 helicopters of
U.S. Registry. We estimate that operators may incur the following costs
in order to comply with this AD. At an average labor rate of $85 per
hour, inspecting the barrel assembly would require about 1 work-hour,
for a cost per helicopter of $85 and a total cost of $765 for the
fleet. If required, replacing a defective cable assembly would require
about 8 work-hours, and required parts would cost about $625, for a
cost per helicopter of $1,305.
