Federal Register / Vol. 78, No. 161 / Tuesday, August 20, 2013 / Proposed Rules 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 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. 

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); 

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.

0735; Directorate Identifier 2013–SW– 

014–AD. 

(a) Applicability 

This AD applies to Bell Model 204B 

helicopters with a cable assembly, part 

number (P/N) 205–001–720–001 installed, 

certificated in any category. 

(b) Unsafe Condition 

This AD defines the unsafe condition as an 

incorrectly machined body on the cable 

assembly, which could prevent the barrel 

assembly from fully engaging in the body 

cavity. This condition could result in 

disengagement of the cable from the barrel, 

failure of the tail rotor pitch control, and 

subsequent loss of control of the helicopter. 

(c) Comments Due Date 

We must receive comments by October 21, 

2013. 

(d) Compliance 

You are responsible for performing each 

action required by this AD within the 

specified compliance time unless it has 

already been accomplished prior to that time. 

(e) Required Actions 

(1) Within 25 hours time in service (TIS), 

inspect each cable assembly to determine if 

there is a false cut on the body of the barrel 

assembly, as depicted in Figure 1 of Bell 

Alert Service Bulletin No. 204B–12–68, dated 

October 10, 2012. 

(2) If there is a false cut, before the first 

flight of each day, inspect the cable assembly 

for separation of the barrel assembly from the 

body. If there is any separation, before further 

flight, replace the cable assembly. 

(3) Within 100 hours TIS, replace the cable 

assembly with an airworthy cable assembly 

that does not have a false cut in the body. 

Replacing the cable assembly is terminating 

action for the inspections required by 

paragraph (e)(2) of this AD. 

(f) Alternative Methods of Compliance 

(AMOC) 

(1) The Manager, Rotorcraft Certification 

Office, FAA, may approve AMOCs for this 

AD. Send your proposal to: Helene Gandy,

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.

SUPPLEMENTARY INFORMATION: 

Comments Invited 

We invite you to participate in this 

rulemaking by submitting written 

comments, data, or views. We also 

invite comments relating to the 

economic, environmental, energy, or 

federalism impacts that might result 

from adopting the proposals in this 

document. The most helpful comments 

reference a specific portion of the 

proposal, explain the reason for any 

recommended change, and include 

supporting data. To ensure the docket 

does not contain duplicate comments, 

commenters should send only one copy 

of written comments, or if comments are 

filed electronically, commenters should 

submit only one time. 

We will file in the docket all 

comments that we receive, as well as a 

report summarizing each substantive 

public contact with FAA personnel 

concerning this proposed rulemaking. 

Before acting on this proposal, we will 

consider all comments we receive on or 

before the closing date for comments. 

We will consider comments filed after 

the comment period has closed if it is 

possible to do so without incurring 

expense or delay. We may change this 

proposal in light of the comments we 

receive. 

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 likely to 

exist or develop on other helicopters of 

the same type design. 

Related Service Information 

We reviewed Bell Alert Service 

Bulletin (ASB) No. UH–1H–12–08, 

dated August 28, 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, 

within 25 hours time in service (TIS), 

inspecting the cable assemblies 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 50 hours TIS. 

Until the cable assembly is replaced, 

this proposed AD would require 

inspecting the assembly for separation 

daily. 

Differences Between This Proposed AD 

and the Service Information 

The ASB specifies inspecting the 

barrel assembly at the next daily 

inspection; the proposed AD specifies 

inspecting within 25 hours TIS. The 

ASB also specifies replacing any 

defective cable assembly at the next 

phase inspection, within 50 hours TIS, 

or by December 31, 2012; the proposed 

AD specifies replacing the cable 

assembly within 50 hours TIS. 

Costs of Compliance 

We estimate that this proposed AD 

would affect 716 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 $60,860 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. 

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: 


sroberts on DSK5SPTVN1PROD with PROPOSALS
Federal Register / Vol. 78, No. 161 / Tuesday, August 20, 2013 / Proposed Rules 51129 

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 proposed 

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 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); 

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.
