AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Bell Model 430 helicopters. This AD 

requires installing a placard on the 

instrument panel and revising the 

limitations section of the rotorcraft 

flight manual (RFM). This AD was 

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. These 

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: This AD is effective December 5, 

2013.

SUPPLEMENTARY INFORMATION: 

Discussion 

On June 7, 2013, at 78 FR 34290, the 

Federal Register published our notice of 

proposed rulemaking (NPRM), which 

proposed to amend 14 CFR part 39 by 

adding an AD that would apply to Bell 

Model 430 helicopters, serial number 

49001 through 49111. The NPRM 

proposed to require installing a placard 

on the instrument panel and revising 

the Operating Limitations section of the 

Model 430 RFM to limit steady-state 

operation between speeds of 71% and 

91%. The proposed requirements were 

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. 

The NPRM was prompted by AD No. 

CF–2005–25, dated July 5, 2005, issued 

by Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada. TCCA issued AD No. CF– 

2005–25 to correct an unsafe condition 

for Model 430 helicopters. TCCA 

advises that 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 TCCA, 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 provided a corresponding 

decal on the instrument panel to inform 

pilots to avoid steady-state operations 

between 71% and 91% turbine speeds. 

The TCCA 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). 

Comments 

After our NPRM (78 FR 34290, June 

7, 2013) was published, we received 

comments from one commenter. 

Request 

Rolls-Royce Corporation requested 

that in addition to requiring the placard 

on the instrument panel, we allow 

operators the option to temporarily 

mark the Nr/Np gauge with colored tape, 

to provide a more visual aide to the 

pilot for the speed avoidance zone. 

We disagree. Marking the glass 

surface of the gauge can create parallax 

issues when viewing the avoidance 

ranges on the gauge, resulting in 

erroneous readings. 

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, TCCA, its 

technical representative, has notified us 

of the unsafe condition described in the 

TCCA AD. We are issuing this AD 

because we evaluated all information 

provided by TCCA, reviewed the 

relevant information, considered the 

comment received, and determined the 

unsafe condition exists and is likely to 

exist or develop on other helicopters of 

the same type design and that air safety 

and the public interest require adopting 

the AD requirements as proposed. 

Differences Between This AD and the 

TCCA AD 

The TCCA AD requires compliance 

within 10 calendar days, while this AD 

requires compliance within 30 days. 

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. 

Costs of Compliance 

We estimate that this AD will affect 

37 helicopters of U.S. Registry. Based on 

an average labor rate of $85 per hour, we 

estimate that operators will incur the 

following costs in order to comply with 

this AD. Amending the RFM requires 

about 0.5 work-hour, for a cost per 

helicopter of about $43 and a cost to 

U.S. operators of $1,591. Installing the 

decal requires about 0.2 work-hour and 

required parts 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 AD will 

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 

helicopters identified in this rulemaking 

action. 

Regulatory Findings 

This AD will not have federalism 

implications under Executive Order 

13132. This AD will 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 this AD:
