65200 Federal Register / Vol. 78, No. 211 / Thursday, October 31, 2013 / Rules and Regulations 

(d) Subject 

Air Transport Association (ATA) of 

America Code 27: Flight Controls. 

(e) Reason 

This AD was prompted by reports of 

movement of the rudder pedals being 

impeded due to corrosion of the trunnion 

shaft of the RFTU. We are issuing this AD to 

detect and correct any sign of rough 

movement or seizure of the trunnion shaft 

and its bushing, which could cause a rudder 

control jam or a large and rapid alternating 

rudder input leading to a structural failure of 

the vertical fin. 

(f) Compliance 

You are responsible for having the actions 

required by this AD performed within the 

compliance times specified, unless the 

actions have already been done. 

(g) Inspection, Replacement, and Lubrication 

Within 200 flight hours or two months 

after the effective date of this AD, whichever 

occurs first: Inspect the RTFU to determine 

whether the serial number is in the range 

from S/N 0008 through 0509 inclusive 

without a suffix ‘B,’ in accordance with the 

Accomplishment Instructions of Bombardier 

Service Bulletin 84–27–60, dated July 12, 

2012. A review of airplane maintenance 

records is acceptable in lieu of this 

inspection if the serial number of the RFTU 

can be conclusively determined from that 

review. 

(1) If the RFTU’s serial number is not in 

the range from S/N 0008 through 0509 

inclusive, or if the serial number has a suffix 

‘B,’ no further action is required for this 

paragraph. 

(2) If the RFTU’s serial number is in the 

range from S/N 0008 through 0509 inclusive, 

including those with a suffix ‘A,’ but not 

including those with suffix ‘B’: Within 200 

flight hours or 2 months, whichever occurs 

first after the effective date of this AD, 

perform an operational check of the RFTU for 

any sign of rough movement or seizure of the 

trunnion or center shaft, in accordance with 

the Accomplishment Instructions of 

Bombardier Service Bulletin 84–27–60, dated 

July 12, 2012. 

(i) If rough movement or seizure of the 

RFTU trunnion or center shaft is found: 

Before further flight, replace the RFTU with 

a new or serviceable RFTU, in accordance 

with the Accomplishment Instructions of 

Bombardier Service Bulletin 84–27–60, dated 

July 12, 2012. 

(ii) If no rough movement or seizure of the 

RFTU trunnion or center shaft is found: 

Before further flight, lubricate the RFTU, in 

accordance with the Accomplishment 

Instructions of Bombardier Service Bulletin 

84–27–60, dated July 12, 2012. Repeat the 

lubrication of the RFTU at intervals not to 

exceed 600 flight hours or 3 months, 

whichever occurs first, until the RFTU is 

replaced with a unit that has a serial number 

outside the affected range or a serial number 

with a suffix ‘B.’ 

(h) Replacement 

For airplanes having an RFTU identified in 

paragraph (g)(2) of this AD: Except as 

required by paragraph (g)(2)(i) of this AD, 

within 5,000 flight hours or 3 years after the 

effective date of this AD, whichever occurs 

first, replace all affected RFTUs with units 

that have a serial number outside the range 

from S/Ns 0008 through 0509 inclusive, or 

that have a serial number with a suffix ‘B,’ 

in accordance with the Accomplishment 

Instructions of Bombardier Service Bulletin 

84–27–60, dated July 12, 2012. Installing 

replacement RFTUs having conformal 

bushings terminates the repetitive lubrication 

requirements of paragraph (g)(2)(ii) of this 

AD for the affected RTFU. 

(i) Parts Installation Limitation 

As of the effective date of this AD, no 

person may install an RFTU P/N 399500– 

1007 with a serial number from S/N 0008 

through 0509 inclusive, including serial 

numbers with suffix ‘A,’ on any airplane, 

except that RFTUs having a serial number 

with suffix ‘B’ may be installed.

SUPPLEMENTARY INFORMATION: 

Discussion 

On June 7, 2013, at 78 FR 34286, 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 407 helicopters, serial numbers 

53000 through 53644. The NPRM 

proposed to require installing a placard 

on the instrument panel below the NR/ 

NP dual tachometer and revising the 

Operating Limitations section of the 

Model 407 RFM to limit steady-state 

operation between speeds of 68.4% to 

87.1%. 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–2004–09R1, dated July 4, 2005, 

issued by Transport Canada Civil 

Aviation (TCCA), which is the aviation 

authority for Canada. TCCA issued AD 

No. CF–2004–09R1 to correct an unsafe 

condition for Model 407 helicopters. 

TCCA advises that several failures of 

third stage turbine wheels used in Rolls 

Royce 250–C30S and 250–C47B engines, 

and three of these failures have occurred 

to the 250–C47B engine used by Bell on 

the Model 407. 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 steadystate operations between 68.4% and 

87.1% 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. 407– 

05–67, dated June 8, 2005 (ASB 407–05– 

67). 

Comments 

After our NPRM (78 FR 34286, 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 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 

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 407–05–67, 

which contains procedures for installing 

a placard on the instrument panel below 

the main rotor RPM (Nr)/power turbine 

RPM (Np) dual tachometer and for 

inserting the RFM changes into the 

flight manual. 

Costs of Compliance 

We estimate that this AD will affect 

472 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 will 

require about 0.5 work-hour, for a cost 

per helicopter of about $43 and a cost 

to U.S. operators of $20,296. Installing 

the decal will require about 0.2 workhour and required parts cost $20, for a 

cost per helicopter of $37 and a cost to 

U.S. operators of $17,464. Based on 

these estimates, the total cost of this AD 

will be $80 per helicopter and $37,760 

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 

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); 


wreier-aviles on DSK5TPTVN1PROD with RULES
65202 Federal Register / Vol. 78, No. 211 / Thursday, October 31, 2013 / Rules and Regulations 

(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.
