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 N
r

### /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:


## 65208 Federal Register / Vol. 78, No. 211 / Thursday, October 31, 2013 / Rules and Regulations

(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. List of Subjects in 14 CFR Part 39
