Airworthiness Directives; Bell

Helicopters 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for Bell 

Model 430 helicopters, which requires 

replacing certain components of the air 

data system. This AD was prompted by 

the discovery of incorrect indicated 

airspeed when the helicopter was tested 

to the cold temperature limits (¥40 

degrees centigrade) required for 

Category A operations. The actions of 

this AD are intended to correct the 

published Vne and to correct the 

indicated airspeed. 

DATES: This AD is effective May 23, 

2013. 

ADDRESSES: For service information 

identified in this AD, contact Bell 

Helicopter Textron Canada Limited,

SUPPLEMENTARY INFORMATION:

Discussion 

On October 22, 2012, at 77 FR 64439, 

the Federal Register published our 

notice of proposed rulemaking (NPRM), 

which proposed to amend 14 CFR part 

39 to include an AD that would apply 

to Bell Model 430 helicopters. That 

NPRM proposed to require replacing 

certain components of the air data 

system. The proposed requirements 

were intended to correct the published 

Vne and to correct the indicated 

airspeed. 

The Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian AD No. 

CF–2005–30, dated August 3, 2005, to 

correct an unsafe condition for the Bell 

Model 430 helicopters. Discrepancies in 

the processing and display of air data 

were revealed when testing at low 

temperatures to minus 40 degrees 

Centigrade (¥40°C). The TCCA advises 

that modification to the instrumentation 

is required to reflect the Vne airspeed 

values tested at temperatures to ¥40°C. 

The TCCA states ‘‘This modification 

affects the software in the Vne 

Overspeed Warning computer (required 

for Category A operations) and in the 

AFCS [Automatic Flight Control 

System] Air Data Computer.’’ TCAA 

issued AD CF–2005–30 to require the 

procedures in Bell Alert Service 

Bulletin (ASB) No. 430–05–35, dated 

June 21, 2005, for replacing the affected 

instruments. Bell also issued ASB No. 

430–01–22, dated April 30, 2001 (ASB 

430–01–22), which provided a 

temporary Rotorcraft Flight Manual 

Supplement and placards with 

information on airspeed corrections. 

TCCA did not issue an AD to mandate 

the provisions of ASB 430–01–22. 

Comments 

We gave the public the opportunity to 

participate in developing this AD, but 

we did not receive any comments on the 

NPRM (77 FR 64439, October 22, 2012). 

FAA’s Determination 

These helicopters have been approved 

by the TCCA and are approved for 

operation in the United States. Pursuant 

to our bilateral agreement with Canada, 

TCCA has notified us of the unsafe 

condition described in the Canadian 

AD. 

We are issuing this AD because we 

evaluated all information provided by 

TCCA and determined the unsafe 

condition exists and is likely to exist or 

develop on other helicopters of the same 

type designs and that air safety and the 

public interest require adopting the AD 

requirements as proposed. 

Differences Between This AD and the 

TCCA AD 

We do not use the compliance date of 

July 31, 2007. 

Costs of Compliance 

We estimate that this AD will affect 

52 helicopters of U.S. registry. We 

estimate that operators may incur the 

following costs in order to comply with 

this AD: 

• $680 to replace the overspeed 

warning computer, pilot and copilot 

airspeed indicators, Vne converter, and 

AFCS air data computer adapter module 

for each helicopter, assuming 8 work 

hours for each helicopter at an average 

labor rate of $85 per work hour, and 

• $46,074 per helicopter for the 

required parts. 


TKELLEY on DSK3SPTVN1PROD with RULES
Federal Register / Vol. 78, No. 75 / Thursday, April 18, 2013 / Rules and Regulations 23115 

Based on these figures, we estimate 

the total cost impact of the AD on U.S. 

operators to be $2,431,208 for the 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: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866; 

(2) Is not a ‘‘significant rule’’ under 

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 AD and placed it in the AD docket.
