AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Bell Model 430 helicopters. This 

proposed AD would require installing a 

placard on the instrument panel and 

revising the limitations section of the 

rotorcraft flight manual (RFM). This 

proposed AD is prompted by several 

incidents of third stage engine turbine 

wheel failures, which were caused by 

excessive vibrations at certain engine 

speeds during steady-state operations. 

The proposed actions are intended to 

alert pilots to avoid certain engine 

speeds during steady-state operations, 

prevent failure of the third stage engine 

turbine, engine power loss, and 

subsequent loss of control of the 

helicopter. 

DATES: We must receive comments on 

this proposed AD by August 6, 2013. 

ADDRESSES: You may send comments by 

any of the following methods: 

• Federal eRulemaking Docket: Go to

Discussion 

Transport Canada (TC), which is the 

aviation authority for Canada, has 

issued TC AD No. CF–2005–25, dated 

July 5, 2005, to correct an unsafe 

condition for Model 430 helicopters. TC 

advises of several failures of third stage 

turbine wheels used in Rolls Royce 250– 

C30S and 250–C47B engines and that a 

similar turbine wheel is installed on the 

250–C40B engine used by Bell on Model 

430 helicopters. According to TC, Rolls 

Royce has determined that detrimental 

vibrations can occur within a particular 

range of turbine speeds, and may be a 

contributing factor to these failures. Bell 

has revised the operating limitations of 

the RFM and has provided a 

corresponding decal on the instrument 

panel to inform pilots to avoid steadystate operations between 71% and 91% 

turbine speeds. 

The TC AD requires amending the 

RFM, advising pilots of the change, and 

installing a decal as described in Bell 

Alert Service Bulletin (ASB) No. 430– 

05–34, dated June 10, 2005 (ASB 430– 

05–34). 

FAA’s Determination 

These helicopters have been approved 

by the aviation authority of Canada and 

are approved for operation in the United 

States. Pursuant to our bilateral 

agreement with Canada, TC, its 

technical representative, has notified us 

of the unsafe condition described in its 

AD. We are proposing this AD because 

we evaluated all known relevant 

information and determined that an 

unsafe condition is likely to exist or 

develop on other helicopters of the same 

type design. 

Related Service Information 

Bell has issued ASB 430–05–34, 

which contains procedures for installing 

a placard on the instrument panel and 

for inserting the RFM changes into the 

flight manual. 

Proposed AD Requirements 

This proposed AD would require 

installing a placard on the instrument 

panel and revising the Operating 

Limitations section of the Model 430 

RFM to limit steady-state operations 

between speeds of 71% and 91%. 

Differences Between This Proposed AD 

and the TC AD 

The TC AD requires compliance 

within 10 calendar days, the proposed 

AD requires compliance within 30 days. 

Costs of Compliance 

We estimate that this proposed AD 

would affect 37 helicopters of U.S. 

Registry. Based on an average labor rate 

of $85 per hour, we estimate that 

operators may incur the following costs 

in order to comply with this AD. 

Amending the RFM would require about 

0.5 work-hours, for a cost per helicopter 

of about $43 and a cost to U.S. operators 

of $1,591. Installing the decal would 

require about 0.2 work-hours and 

required parts would cost $20, for a cost 

per helicopter of $37 and a cost to U.S. 

operators of $1,369. Based on these 

estimates, the total cost of this proposed 

AD would be $80 per helicopter and 

$2,960 for the U.S. operator fleet. 

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.

Uniformed Services Members and 

Their Dependents 

AGENCY: Office of the Secretary, DoD. 

ACTION: Proposed rule. 

SUMMARY: This proposed rule would 

establish an exception to the usual rule 

that TRICARE Prime enrollment fees are 

uniform for the group of retirees and 

their dependents. Survivors and 

medically retired members are part of 

the retiree group under TRICARE rules. 

This exception would allow Survivors 

of Active Duty Deceased Sponsors and 

Medically Retired Uniformed Services 

Members and their Dependents enrolled 

in Prime to be exempt from future 

increases in TRICARE Prime enrollment 

fees. The Prime beneficiaries in these 

categories prior to 10/1/2013 would 

have their annual enrollment fee frozen 

at their current annual rate (FY 2011 

rate $230 per single or $460 per family, 

FY 2012 rate $260 or $520, or the FY 

2013 rate $269.38 or $538.56). The 

beneficiaries added to these categories 

on or after 10/1/2013 would have their 

fee frozen at the rate in effect at the time 

they are classified in either category and 

enroll in Prime or, if not enrolling, at 

the rate in effect at the time of 

enrollment. The fee remains frozen as 

long as at least one family member 

remains enrolled in Prime and there is 

not a break in enrollment. The fee 

charged for the dependent(s) of a 

Medically Retired Uniformed Services 

Member would not change if the 

dependent(s) was later re-classified a 

Survivor. 

DATES: Written comments received at 

the address indicated below by August 

6, 2013 will be considered and 

addressed in the final rule. 

ADDRESSES: You may submit comments, 

identified by docket number and or RIN
