AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

originated by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

Three events have been reported where 

insulation material was found to be fouling 

pulleys in the aileron interconnect circuit in 

the cabin roof area. * * * 

Interference between the cable and the 

insulation bag causes the material to be 

drawn into the gap between the pulley and 

the pulley guard. This condition, if not 

detected and corrected, could lead to 

restricted aileron movement and 

consequently, reduced control of the 

aeroplane. 

* * * * * 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective 

October 7, 2010. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of October 7, 2010.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM was published in the Federal 

Register on May 19, 2010 (75 FR 27959). 

That NPRM proposed to correct an 

unsafe condition for the specified 

products. The MCAI states: 

Three events have been reported where 

insulation material was found to be fouling 

pulleys in the aileron interconnect circuit in 

the cabin roof area. The insulation material 

is contained in a bag, the material of which 

tends to become brittle with age. During the 

production life of the aeroplane type, several 

methods of bag retention were applied, all of 

which involved puncturing the bag. This 

puncture tends to result in a tear, which, if 

detected in time, can be repaired with tape; 

however, the affected cabin roof area is not 

frequently accessed for inspection. Over 

time, the weight of the bag also tends to 

cause tears in the material, making the 

insulation material sag, thereby causing 

interference with the cable and pulley. 

Interference between the cable and the 

insulation bag causes the material to be 

drawn into the gap between the pulley and 

the pulley guard. This condition, if not 

detected and corrected, could lead to 

restricted aileron movement and 

consequently, reduced control of the 

aeroplane. 

For the reasons described above, this 

[EASA] AD requires the installation of 

additional guards, bolts and nuts on the 

aileron interconnect cable pulleys at frame 29 

(left and right). 

This [EASA] AD has been revised to 

exclude aeroplanes from the Applicability 

that have been modified to freighter 

configuration in accordance with BAE 

Systems modification No. HCM50200B. As 

this modification includes the removal of the 

insulation bags, the unsafe condition that is 

addressed by this [EASA] AD cannot exist or 

develop on those aeroplanes. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM or 

on the determination of the cost to the 

public. 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed. 

Differences Between This AD and the 

MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 

general, agree with their substance. But 

we might have found it necessary to use 

different words from those in the MCAI 

to ensure the AD is clear for U.S. 

operators and is enforceable. In making 

these changes, we do not intend to differ 

substantively from the information 

provided in the MCAI and related 

service information. 

We might also have required different 

actions in this AD from those in the 


emcdonald on DSK2BSOYB1PROD with RULES
53856 Federal Register / Vol. 75, No. 170 / Thursday, September 2, 2010 / Rules and Regulations 

MCAI in order to follow our FAA 

policies. Any such differences are 

highlighted in a NOTE within the AD. 

Costs of Compliance 

We estimate that this AD will affect 

1 product of U.S. registry. We also 

estimate that it will take about 5 workhours per product to comply with the 

basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Required parts will cost about $340 per 

product. Where the service information 

lists required parts costs that are 

covered under warranty, we have 

assumed that there will be no charge for 

these parts. As we do not control 

warranty coverage for affected parties, 

some parties may incur costs higher 

than estimated here. Based on these 

figures, we estimate the cost of this AD 

to the U.S. operator to be $765. 

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 above, I 

certify this AD: 

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); and 

3. 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 a regulatory evaluation 

of the estimated costs to comply with 

this AD and placed it in the AD docket. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Operations office between 9 a.m. 

and 5 p.m., Monday through Friday, 

except Federal holidays. The AD docket 

contains the NPRM, the regulatory 

evaluation, any comments received, and 

other information. The street address for 

the Docket Operations office (telephone 

(800) 647–5527) is in the ADDRESSES

SUMMARY: This document publishes in 

the Federal Register an amendment 

adopting Airworthiness Directive (AD) 

2010–16–51, which was sent previously 

to all known U.S. owners and operators 

of Eurocopter France (Eurocopter) 

Model SA330J helicopters by individual 

letters. This AD requires, within 10 

hours time-in-service (TIS), inspecting 

for a gap between the main gearbox 

(MGB) oil cooling fan assembly (fan) 

rotor blade and the upper section of the 

guide vane bearing housing. This 

inspection must be accomplished by 

using a feeler gauge attached to a rigid 

rod. If the feeler gauge cannot be 

inserted between the blade and the 

housing, this AD requires replacing the 

two fan rotor shaft bearings with two 

airworthy bearings. This AD is 

prompted by the separation of a fan 

rotor blade that caused puncture holes 

in the transmission deck. This 

condition, if not corrected, could lead to 

damage to the hydraulic lines and flight 

controls, and subsequent loss of control 

of the helicopter. 

DATES: Effective September 17, 2010, to 

all persons except those persons to 

whom it was made immediately 

effective by Emergency AD 2010–16–51, 

issued on July 19, 2010, which 

contained the requirements of this 

amendment. 

The incorporation by reference of 

certain publications listed in the 

regulations is approved by the Director 

of the Federal Register as of September 

17, 2010. 

Comments for inclusion in the Rules

SUPPLEMENTARY INFORMATION: On July 

19, 2010, we issued Emergency AD 

2010–16–51 for Eurocopter Model 

SA330J helicopters, which requires, 

within 10 hours TIS, inspecting for a 

gap between the MGB fan rotor blade 

and the upper section of the guide vane 

bearing housing over the entire width of 

the blade. The inspection must be 

accomplished by using a 0.2 millimeter 

(mm) (0.008 inch) feeler gauge attached 

to a rigid rod. If the feeler gauge cannot 

be inserted between the upper blade and 

the upper housing, the Emergency AD 

requires replacing the two fan rotor 

shaft bearings with two airworthy 

bearings. That action was prompted by 

a rotor burst of MGB oil fan. 

Investigation of the incident has shown 

that some fan rotor blades struck the 

upper area of the guide vane bearing 

housing of the fan and separated from 

the rotor, striking the MGB 

compartment environment, and 

punctured holes in the transmission 

deck. This interference was due to 

internal degradation of the bearings of 

the fan rotor shaft. This condition, if not 

corrected, could lead to fan rotor burst, 

damage to the hydraulic lines and flight 

controls, 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 

Community, notified us that an unsafe 

condition may exist on these helicopter 

models. EASA advises of a case of rotor 

burst of a fan. Investigation has shown 

that some fan rotor blades interfered 

with the upper area of the guide vane 

bearing housing of the fan. The blades 

detached from the rotor, impacted the 

MGB compartment environment, and 

punctured holes in the transmission 

deck. This interference was due to 

internal degradation of the bearings of
