SUMMARY: We are adopting a new 

airworthiness directive (AD) for 

Eurocopter Model AS350B, AS350BA, 

AS350B1, AS350B2, AS350B3, AS350C, 

AS350D, AS350D1, AS355E, AS355F, 

AS355F1, AS355F2, AS355N, and 

AS355NP helicopters. This AD requires 

certain inspections of each tail rotor 

pitch horn assembly (pitch horn) for a 

crack, and if there is a crack, before 

further flight, replacing the pitch horn 

with an airworthy pitch horn. This AD 

is prompted by a report of a crack in the 

yoke of a pitch horn. These actions are 

intended to detect a crack in the pitch 

horn to prevent failure of the pitch horn, 

loss of the anti-torque function, and 

subsequent loss of control of the 

helicopter.

rulemaking during the comment period. 

We will consider all the comments we 

receive and may conduct additional 

rulemaking based on those comments. 

Discussion 

We are adopting a new AD for the 

specified Eurocopter helicopters. This 

AD requires visually inspecting each 


emcdonald on DSK67QTVN1PROD with RULES
63854 Federal Register / Vol. 78, No. 207 / Friday, October 25, 2013 / Rules and Regulations 

pitch horn for a crack. This AD also 

requires, if there is a crack, before 

further flight, replacing the pitch horn 

with an airworthy pitch horn. This AD 

is prompted by a report of a crack in the 

yoke of a pitch horn. These actions are 

intended to detect a crack in the pitch 

horn to prevent failure of the pitch horn, 

loss of the anti-torque function, and 

subsequent loss of control of the 

helicopter. 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD No. 2013– 

0133, dated June 28, 2013, to correct an 

unsafe condition for the Model AS350B, 

AS350BA, AS350BB, AS350B1, 

AS350B2, AS350B3, AS350D, AS355E, 

AS355F, AS355F1, AS355F2, AS355N, 

and AS355NP helicopters. EASA 

advises of an ongoing investigation of a 

crack in the yoke of a pitch horn for 

which a cause has not been determined. 

The EASA AD requires repetitive visual 

inspections of each pitch horn for a 

crack and replacing the pitch horn with 

a serviceable assembly if a crack is 

found. EASA states that its AD is an 

interim action and further action may 

follow. 

FAA’s Determination 

These helicopters have been approved 

by the aviation authority of France and 

are approved for operation in the United 

States. Pursuant to our bilateral 

agreement with France, EASA, its 

technical representative, has notified us 

of the unsafe condition described in the 

EASA AD. We are issuing this AD 

because we evaluated all information 

provided by EASA and determined the 

unsafe condition exists and is likely to 

exist or develop on other helicopters of 

these same type designs. 

Related Service Information 

Eurocopter has issued one Emergency 

Alert Service Bulletin, Revision 1, dated 

June 25, 2013 (EASB), with four 

different numbers. EASB No.05.00.74 is 

for Models AS350B, B1, B2, B3, BA, and 

D; the non-FAA type certificated Model 

AS350BB; and the non-FAA type 

certificated military Model AS350L1 

helicopters. EASB No. 05.00.49 is for 

non-FAA type certificated military 

Models AS550A2, C2, C3, and U2 

helicopters. EASB No. 05.00.65 is for 

Models AS355E, F, F1, F2, N, and NP 

helicopters. EASB No. 05.00.44 is for 

non-FAA type certificated military 

Model AS555AF, AN, SN, UF, and UN 

helicopters. Eurocopter has been 

informed of a case of a crack on the yoke 

of a pitch horn, which may lead to 

failure of the pitch horn, resulting in 

loss of the anti-torque function. The 

EASB specifies a check for cracks on the 

yokes of the two pitch horns and 

specifies replacing any cracked pitch 

horn. The EASB states that it may be 

necessary to modify the log card of the 

tail rotor blade assembly due to some of 

the pitch horn part numbers being 

recorded incorrectly. 

AD Requirements 

This AD requires: 

• Based on the hours time-in-service, 

within a specified time, visually 

inspecting each pitch horn for a crack in 

the areas shown in Figure 1 of the 

EASB. 

• If there is a crack, before further 

flight, replacing the pitch horn with an 

airworthy pitch horn. 

• Before installing any pitch horn, P/ 

N 350A121368, dye penetrant 

inspecting it for a crack. 

Differences Between This AD and the 

EASA AD 

The EASA AD applies to Eurocopter 

Model AS350BB that does not have an 

FAA type certificate and therefore is not 

a part of this AD. The EASA AD does 

not apply to Eurocopter Model AS350C 

or the AS350D1, but this AD does 

because those models have an FAA type 

certificate and may have the applicable 

pitch horn installed. This AD requires a 

dye-penetrant inspection before 

installing a pitch horn; the EASA AD 

does not. The EASA AD applies to parts 

with less than 135 hours TIS, while this 

AD does not. The EASA AD requires the 

pitch horn inspection to be repeated 

every 165 flight hours, and this AD does 

not. 

Interim Action 

We consider this AD to be an interim 

action. If final action is later identified, 

we might consider further rulemaking 

then. 

Costs of Compliance 

We estimate that this AD will affect 

938 helicopters of U.S. Registry. We 

estimate that operators may incur the 

following costs to comply with this AD. 

Labor costs are estimated at $85 per 

work hour. We estimate .1 work hour to 

visually inspect a pitch horn for a total 

of $8.50 per helicopter and $7,973 for 

the fleet. We estimate 1 work hour to do 

a dye-penetrant inspection, for a total 

cost of $85 per helicopter. We estimate 

1 work hour to replace a part if 

necessary, and a cost for required parts 

of $1,946, for a total cost of $2,031 per 

helicopter. 

FAA’s Justification and Determination 

of the Effective Date 

Providing an opportunity for public 

comments before adopting these AD 

requirements would delay 

implementing the safety actions needed 

to correct this known unsafe condition. 

Therefore we find that the risk to the 

flying public justifies waiving notice 

and comment prior to adopting this rule 

because the corrective actions must be 

accomplished, for helicopters flying 

with parts with more than 155 hours 

TIS, within 10 hours TIS, a short time 

period based on the average flight-hour 

utilization rate of these helicopters. 

Since an unsafe condition exists that 

requires the immediate adoption of this 

AD, we determined that notice and 

opportunity for public comment before 

issuing this AD are impracticable and 

contrary to the public interest and that 

good cause exists for making this 

amendment effective in less than 30 

days. 

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 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, 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); 


emcdonald on DSK67QTVN1PROD with RULES
Federal Register / Vol. 78, No. 207 / Friday, October 25, 2013 / Rules and Regulations 63855 

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.

ACTION: Final rule; request for 

comments. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 747–8F 

and 747–8 series airplanes. This AD 

requires a detailed inspection of the 

power control actuator (PCA) 

installation to determine if a bushing is 

installed, a general visual inspection 

between the horizontal stabilizer rear 

spar and the elevator front spar and 

between certain stabilizer stations for 

defects and damage, and corrective 

actions if necessary. This AD was 

prompted by a report of unusual noise 

coming from the left inboard elevator 

during a functional check of the ram air 

turbine system, and a determination that 

a bushing was not installed. We are 

issuing this AD to detect and correct 

non-installation of bushings. If the
