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.

Adoption of the Amendment 

■ Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 14 CFR part 39 as 

follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new AD: 

2010–10–14 Eurocopter France: 

Amendment 39–16293. Docket No. 

FAA–2010–0491; Directorate Identifier 

2009–SW–64–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective June 7, 2010. 

Other Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Model AS332L2 

helicopters, with a main rotor mast assembly 

(mast) that has not been modified per MOD 

0743714, installed, certificated in any 

category. 

Note 1: MOD 0743714 includes replacing 

the plastic peel shim with a stainless steel 

peel shim, installing improved swashplate 

bearing attachment screws, and increasing 

the torque on those screws. 

Reason 

(d) The mandatory continued 

airworthiness information (MCAI) AD was 

issued after the discovery of broken 

swashplate bearing attaching screw heads. 

Failure of these screw heads could lead to the 

loss of the coupling between the non-rotating 

and the rotating swashplate. This AD is 

intended to prevent loss of power to the 

rotating swashplate and subsequent loss of 

control of the helicopter. 

Actions and Compliance 

(e) For each mast that has less than 750 

hours TIS since it was installed on any 

helicopter or since its last overhaul, within 

20 hours time-in-service (TIS), unless already 

done, and thereafter at intervals not to exceed 

25 hours TIS, and for each mast that has 750 

or more hours TIS since it was installed on 

any helicopter or since its last overhaul, 

within 25 hours TIS, unless already done, 

and thereafter at intervals not to exceed 25 

hours TIS: 

(1) Inspect for the presence of each mast 

swashplate bearing attachment screw head by 

either using a mirror or by feeling for the 

screw heads under the flange. Do the 

inspections by following the 

Accomplishment Instructions, Operational 

Procedure, paragraphs 2.B.1. through 2.B.2. 

and Figure 1, of Eurocopter Alert Service 

Bulletin (ASB) No. 62.00.66, dated 

September 13, 2006, except this AD does not 

require you to send the assembly to an 

‘‘approved repair center for investigation and 

reconditioning.’’ 

(2) If an attachment screw head is missing, 

before further flight, replace the unairworthy 

mast with an airworthy mast. 

Note 2: If you have complied with ASB No. 

62.00.66, dated September 13, 2006, you 

have met the intent of this AD. 

Differences Between the FAA AD and the 

MCAI AD 

(f) This AD differs from the MCAI AD as 

follows: 

(1) This AD does not require you to send 

the assembly to an ‘‘approved repair center 

for investigation and reconditioning.’’ 

(2) This AD uses ‘‘hours TIS’’ instead of 

‘‘flying hours.’’ 

(3) This AD does not apply to non-installed 

parts. 

(4) This AD does not include an inspection 

for masts that were inspected per a previous 

MCAI AD. 

Other Information 

(g) Alternative Methods of Compliance 

(AMOCs): The Manager, Safety Management 

Group, Rotorcraft Directorate, FAA, has the 

authority to approve AMOCs for this AD, if 

requested, using the procedures found in 14

ACTION: Final rule. 

SUMMARY: We are superseding an 

existing 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: 


cprice-sewell on DSK8KYBLC1PROD with RULES
28472 Federal Register / Vol. 75, No. 98 / Friday, May 21, 2010 / Rules and Regulations 

A specific batch of nose landing gear (NLG) 

and NLG door selector valves, part number 

(P/N) 601R75146–1 (Kaiser Fluid 

Technologies P/N 750006000), may have had 

their end caps incorrectly lock-wired and/or 

incorrectly torqued during assembly. This 

condition can lead to the end cap backing off, 

with consequent damage to a seal and 

internal leakage within the valve. 

Subsequently, if electrical power is 

transferred or removed from the aircraft 

before the NLG safety pin is installed, any 

pressure, including residual pressure, in the 

No. 3 hydraulic system can result in an 

uncommanded NLG retraction. 

* * * * * 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective June 

25, 2010. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of June 25, 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 February 25, 2010 (75 FR 

8559), and proposed to supersede AD 

2007–14–02, Amendment 39–15124 (72 

FR 38004, July 12, 2007). 

That NPRM proposed to correct an 

unsafe condition for the specified 

products. The MCAI states: 

A specific batch of nose landing gear (NLG) 

and NLG door selector valves, part number 

(P/N) 601R75146–1 (Kaiser Fluid 

Technologies P/N 750006000), may have had 

their end caps incorrectly lock-wired and/or 

incorrectly torqued during assembly. This 

condition can lead to the end cap backing off, 

with consequent damage to a seal and 

internal leakage within the valve. 

Subsequently, if electrical power is 

transferred or removed from the aircraft 

before the NLG safety pin is installed, any 

pressure, including residual pressure, in the 

No. 3 hydraulic system can result in an 

uncommanded NLG retraction. 

Although there have been no such cases 

reported on the Challenger models covered 

by this directive, there have been six cases 

reported on the CRJ (CL600–2B19) aircraft, 

one of which resulted in the collapse of the 

NLG at the departure gate. 

This directive mandates a check of the 

NLG and NLG door selector valves installed 

on all aircraft in the Applicability section 

* * *. Depending on the results; 

replacement, rework and/or additional 

identification of the valves may be required. 

This [MCAI] revision corrects a Service 

Bulletin number in the Corrective Actions 

table. 

Notes: 1. The check is required whether or 

not an aircraft has previously been checked 

in accordance with AD CF–2006–16R1 (now 

superseded and cancelled by this AD). This 

is necessary since, following the issuance of 

AD CF–2006–16R1, it has been determined 

that the serial number (S/N) range of the 

affected valves requires expansion from the 

previous upper limit of S/N 0767 to S/N 2126 

and the exact location of each of these 

additional valves is unknown. 

2. Valves that have a S/N with suffix ‘‘T’’ 

have been manufactured by Tactair Fluid 

Controls Inc. and do not require any 

corrective action. 

3. Valves manufactured by Kaiser Fluid 

Technologies, P/N 750006000, with S/N 0001 

through 2126, and ink stamp ‘‘SB750006000– 

1’’, have already been checked and reworked 

as necessary and do not require any 

additional corrective action. 

4. The Illustrated Parts Catalog, for each of 

the models covered in the Applicability 

section * * *, gives instructions not to 

install a valve manufactured by Kaiser Fluid 

Technologies, P/N 750006000, with S/N 0001 

through 2126, if the marking ‘‘SB750006000– 

1’’ is not ink stamped on the valve. 

5. CL–600–2B16 (CL–605) aircraft, S/Ns 

5701 and subsequent, are not affected by this 

directive. They were delivered with valves, 

P/N 750006000, that have either a S/N with 

suffix ‘‘T’’ or have the ink stamp marking 

‘‘SB750006000–1’’. 

We have clarified the applicability of 

this AD by removing serial numbers 

5666 through 5699 that were included 

in AD 2007–14–02. Those serial 

numbers do not exist for the affected 

airplane models in this AD. 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 

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 

about 82 products of U.S. registry. 

The actions that are required by AD 

2007–14–02 and retained in this AD 

take about 1 work-hour per product, at 

an average labor rate of $85 per work 

hour. Based on these figures, the 

estimated cost of the currently required 

actions is $85 per product. 

We estimate that it will take about 1 

work-hour per product to comply with 

the new basic requirements of this AD. 

The average labor rate is $85 per workhour. Based on these figures, we 

estimate the cost of the new basic 

requirements of this AD to U.S. 

operators to be $6,970, or $85 per 

product. 

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 


cprice-sewell on DSK8KYBLC1PROD with RULES
Federal Register / Vol. 75, No. 98 / Friday, May 21, 2010 / Rules and Regulations 28473 

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

section. Comments will be available in 

the AD docket shortly after receipt.

RESTATEMENT OF REQUIREMENTS OF 

AD 2007–14–02 WITH NEW SERVICE 

INFORMATION BUT NO CHANGES TO 

ACTIONS: 

Inspection and Corrective Action 

(g) For airplanes having serial numbers (S/ 

Ns) as identified in the service bulletins 

specified in Table 1 of this AD, as applicable: 

Within 500 flight hours or 12 months after 

August 16, 2007 (the effective date AD 2007– 

14–02), whichever occurs first, inspect to 

determine the manufacturer part numbers (P/ 

Ns) and serial numbers of the selector valves 

of the nose landing gear (NLG) and nose gear 

door. A review of airplane maintenance 

records is acceptable in lieu of this 

inspection if the serial numbers of the 

selector valves can be conclusively 

determined from that review. For any subject 

selector valve having Tactair Fluid Controls 

P/N 750006000 and a S/N from 0001 through 

0767 inclusive, before further flight, do 

related investigative (including a general 

visual inspection for proper installation of 

the lock wire of the end cap) and corrective 

actions; in accordance with the applicable 

service bulletin identified in Table 1 of this 

AD. After the effective date of this AD, use

installation, or assembly to detect obvious 

damage, failure, or irregularity. This level of 

inspection is made from within touching 

distance unless otherwise specified. A mirror 

may be necessary to ensure visual access to 

all surfaces in the inspection area. This level 

of inspection is made under normally 

available lighting conditions such as 

daylight, hangar lighting, flashlight, or 

droplight and may require removal or 

opening of access panels or doors. Stands, 

ladders, or platforms may be required to gain 

proximity to the area being checked.’’ 

Note 3: The service bulletins identified in

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: 

In the door 2 area, the hat-racks are 

supplied with a basic wire harness which 

includes ‘‘Oxygen Masks’’ activation. 

In case of a monument installation, the 

respective non-used hat-rack connections 

between monument and outer skin are put on 

stow. It was noticed in production, that the 

distance between the stowed wire harness 

and the monument could be too small. This 

condition, if not corrected, could lead to the 

short circuit of wires dedicated to oxygen, 

which, in case of emergency, could result in 

a large number of passenger oxygen masks 

not being supplied with oxygen, possibly 

causing personal injuries. 

* * * * * 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective June 

25, 2010. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of June 25, 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 October 19, 2009 (74 FR 

53440). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states:
