37152 Federal Register / Vol. 78, No. 119 / Thursday, June 20, 2013 / Proposed Rules 

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.

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for Bell 

Model 206L, L–1, L–3, and L–4 

helicopters. This proposed AD would 

require measuring each main rotor (M/ 

R) blade spar space to determine 

whether it is oversized and reidentifying 

the blade and reducing the life limit of 

the blade if the spar spacer is oversized. 

This proposed AD is prompted by the 

manufacture of certain main rotor 

blades with an oversized spar spacer 

and the determination to reduce the life 

limits of those main rotor blades. The 

proposed actions are intended to 

prevent failure of a M/R blade and 

subsequent loss of control of the 

helicopter. 

DATES: We must receive comments on 

this proposed AD by August 19, 2013.

Discussion 

Transport Canada Civil Aviation 

(TCAA), which is the aviation authority 

for Canada, has issued AD No. CF– 

2011–43, dated November 10, 2011, to 

correct an unsafe condition for Bell 

Model 206L, L–1, L–3, and L–4 

helicopters. TCAA advises that, during 

manufacturing, some M/R blades were 

inadvertently fitted with oversized spar 

spacers, which reduces the life of the 

blades from 3600 to 2300 hours ‘‘air 

time.’’ As a result, TCCA has mandated 

procedures to reidentify blades that 

have oversized spar spacers with new 

part numbers and reduce the life 

limitation for such blades. 

FAA’s Determination 

These helicopters have been approved 

by TCAA and are approved for 

operation in the United States. Pursuant 

to our bilateral agreement with Canada, 

TCAA, 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 issued Alert Service Bulletin No. 

206L–09–163, dated November 13, 

2009, which specifies inspecting certain 

M/R blades for oversized spar spacers 

and reidentifying and reducing the life 

limit of any blade with an oversized 

spar spacer from 3600 to 2300 flight 

hours. 

Proposed AD Requirements 

This proposed AD would require, 

within a specified time, measuring the 

M/R blade spar spacer. If a blade is 

fitted with an oversized spacer, this AD 

would require reidentifying the blade, 

reducing the life limit for the blade from 

3,600 hours time-in-service (TIS) to 

2,300 hours TIS, and making an entry 

on the component history card or 

equivalent record. 

Differences between This Proposed AD 

and the EASA AD 

TCAA requires compliance time 

within 100 hours air time or 30 days; 

this proposed AD would require 

compliance within 100 hours TIS. 

Costs of Compliance 

We estimate that this proposed AD 

would affect 688 helicopters of U.S. 

Registry. 

We estimate that operators may incur 

the following costs in order to comply 

with this AD. It would take about 2.5 

work hours to measure the spar spacer 

and reidentify the blade at $85 per work 

hour for a total of $213 per helicopter. 

According to Bell’s service 

information some of the costs of this 

proposed AD may be covered under 

warranty, thereby reducing the cost 

impact on affected individuals. We do 

not control warranty coverage by Bell. 

Accordingly, we have included all costs 

in our cost estimate. 

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);

4. Will not have a significant 

economic impact, positive or negative,

We prepared an economic evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the
