AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for Agusta 

Model A109A, A109AII, and A109C 

helicopters with a certain third stage 

turbine wheel installed. 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 19, 2013. 

ADDRESSES: You may send comments by 

any of the following methods:

Discussion 

The European Aviation Safety Agency 

(EASA), which is the aviation authority 

for Italy, has issued EASA AD No. 

2009–0037–E, dated February 19, 2009, 

to correct an unsafe condition for 

Agusta Model A109A, A109AII, and 

A109C helicopters with a Rolls Royce 

Corporation (RRC) engine Model 250– 

C20B or 250–C20R/1 having a third 

stage turbine wheel part number (P/N) 

23065833 installed. EASA advises that 

following several third stage turbine 

wheel failures, the engine type 

certificate holder, RRC, issued 

Commercial Engine Bulletin (CEB) A– 

1400 Revision 3, dated January 19, 2009 

(CEB A–1400), to introduce an 

operational limitation on the power 

turbine (N2) speed range (95% to 97%) 

for more than 60 seconds in single or 

cumulative events for engines with the 

third stage turbine wheel P/N 23065833 

installed. 

The EASA AD requires amending the 

RFMs and installing a placard as 

described in Agusta Bollettino Tecnico 

No. 109–129, dated February 16, 2009 

(BT 109–129). The EASA AD also states 

to avoid steady-state operation in the 

95% to 97% N2 range for more than 60 

seconds, and requires the corrective 

actions of CEB A–1400 if that limitation 

is exceeded. 

FAA’s Determination 

These helicopters have been approved 

by the aviation authority of Italy and are 

approved for operation in the United 

States. Pursuant to our bilateral 

agreement with Italy, EASA, 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 

Agusta has issued BT 109–129, which 

contains procedures for installing a 

placard on the instrument panel below 

or near the engine and rotor RPM power 

turbine (N2) indicator 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 adjacent to the engine and rotor 

RPM power turbine (N2) indicator and 

revising the Operating Limitations 

sections of the Model A109A, A109AII, 

and A109C RFMs to limit steady-state 

operations between speeds of 95% and 

97%. 

Costs of Compliance 

We estimate that this proposed AD 

would affect 40 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 

0.25 work-hour, for a cost per helicopter 

of about $22 and a cost to U.S. operators 

of $880. Installing the decal would 

require about 0.2 work-hours, and 

required parts would cost about $5, for 

a cost per helicopter of $22 and a cost 

to U.S. operators of $880. Based on 

these estimates, the total cost of this 

proposed AD would be $44 per 

helicopter and $1,760 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.
