ACTION: Supplemental notice of 

proposed rulemaking (SNPRM); 

reopening of comment period. 

SUMMARY: We are revising and 

reopening the comment period for an 

earlier notice of proposed rulemaking 

(NPRM) for certain Bell Helicopter 

Textron Canada Limited (Bell) Model 

206L–3 and 206L–4 helicopters. The 

NPRM proposes to require installing a 

placard and revising the limitations 

section of the rotorcraft flight manual 

(RFM). The NPRM was prompted by 

several incidents of third stage engine 

turbine wheel failures caused by 

excessive vibrations at certain engine 

speeds during steady-state operations. 

This action proposes to revise the 

NPRM by adding certain Model 206L1 

helicopters to the applicability, 

excluding certain Model 206L3 and 

206L4 helicopters from the 

applicability, and changing the 

procedures for updating the RFM. Since 

these actions impose an additional 

burden over that proposed in the NPRM, 

we are reopening the comment period to 

allow the public the chance to comment 

on these proposed changes. 

DATES: We must receive comments on 

this SNPRM by December 2, 2014. 

ADDRESSES: You may send comments by 

any of the following methods:

Discussion 

We issued an NPRM to amend 14 CFR 

part 39 to add an airworthiness directive 

(AD) that would apply to certain Bell 

Model 206L–3 and 206L–4 helicopters. 

The NPRM was published in the 

Federal Register on June 7, 2013 (78 FR 

34282). The NPRM proposed to require 

installing a placard on the instrument 

panel below the dual tachometer and 

revising the Operating Limitations 

section of the Model 206L3 and 206L4 

RFMs by inserting pages that limit 

steady-state operations between speeds 

of 71.8% and 91.5%. 

The NPRM was prompted by 

Transport Canada Civil Aviation (TCCA) 

AD No. CF–2005–28R1, dated June 14, 

2007, to correct an unsafe condition for 

certain Model 206L–3 and 206L–4 

helicopters. TCCA, which is the aviation 

authority for Canada, advises of several 

failures of third stage turbine wheels 

used in Rolls-Royce 250–C30S and 250– 

C47B engines. According to TCCA, 

Rolls-Royce 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 RFM and provided a 

corresponding decal to inform pilots to 

avoid steady-state operations between 

71.8% and 91.5% turbine speeds. The 

TCCA AD requires amending the RFMs, 

advising pilots of the change, and 

installing a decal as described in Bell 

Alert Service Bulletin (ASB) No. 206L– 

05–134, dated June 8, 2005, or later 

revisions. 


rmajette on DSK2TPTVN1PROD with PROPOSALS
59696 Federal Register / Vol. 79, No. 192 / Friday, October 3, 2014 / Proposed Rules 

Actions Since Previous NPRM was 

Issued 

Since we issued the NPRM (78 FR 

34282, June 7, 2013), we determined 

that Bell Model 206L1 helicopters with 

Engine Upgrade Kit Part Number (P/N) 

206–706–520 installed should be 

included in the applicability. Engine 

Upgrade Kit P/N 206–706–520 replaces 

the Rolls-Royce 250–C28B engine with 

a Rolls-Royce 250–C30P engine. The 

condition causing the failures of third 

stage turbine wheels used in RollsRoyce 250–C30S and 250–C–47B 

engines could also exist in Rolls-Royce 

250–C30P engines. Lastly, we have 

determined that Bell Model 206L3 and 

206L4 helicopters having Rolls-Royce 

250–C20R engines installed under 

Supplemental Type Certificate (STC) 

number SR00036SE are exempt from the 

requirements of the proposed AD 

because that engine is not affected by 

the unsafe condition. This SNPRM also 

changes the procedures for modifying 

the RFM Limitations Section from 

inserting revised pages to making pen 

and ink changes. 

Comments 

We gave the public the opportunity to 

comment on the previous NPRM (78 FR 

34282, June 7, 2013), and we received 

a comment 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 

We are proposing this SNPRM 

because we evaluated all known 

relevant information and determined 

that an unsafe condition is likely to 

exist or develop on other products of 

these same type designs. Certain 

changes described above expand the 

scope of the original NPRM (78 FR 

34282, June 7, 2013). As a result, we 

have determined that it is necessary to 

reopen the comment period to provide 

additional opportunity for the public to 

comment on this SNPRM. 

Related Service Information 

Bell issued ASB No. 206L–05–134, 

Revision A, dated April 9, 2007, which 

describes procedures for installing a 

placard on the instrument panel below 

the main rotor RPM (Nr)/power turbine 

RPM (N2) dual tachometer and for 

inserting the RFM changes into the 

flight manual. Revision A of the ASB 

was issued to exclude Bell Model 206L– 

3 and 206L–4 helicopters with 250– 

C20R engines installed under STC No. 

SR00036SE from the requirements of the 

ASB. 

Proposed Requirements of the SNPRM 

This proposed AD would require 

installing a placard on the instrument 

panel below the NR/N2 dual tachometer 

and also requires revising the Operating 

Limitations section of the Model 206L3 

and 206L4 RFMs to limit steady-state 

operations between speeds of 71.8% 

and 91.5%. 

Differences Between This Supplemental 

NPRM and the TCCA AD 

The TCCA AD requires compliance 

within 10 calendar days; this proposed 

AD would require compliance within 30 

days. This proposed AD would be 

applicable to Model 206L–1 helicopters 

with Engine Upgrade Kit P/N 206–706– 

520 installed because the same unsafe 

condition exits on this model, and the 

TCCA AD is not. 

Costs of Compliance 

We estimate that this proposed AD 

would affect 616 helicopters of U.S. 

Registry. We estimate that operators 

may incur the following costs in order 

to comply with this AD. Based on an 

average labor rate of $85 per hour, 

amending the RFM would require about 

0.5 work-hour, for a cost per helicopter 

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

of $26,488. Installing the decal would 

require about 0.2 work-hour, and 

required parts would cost $20, for a cost 

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

operators of $22,792. Based on these 

estimates, the total cost of this proposed 

AD would be $80 per helicopter and 

$49,280 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 

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.
