AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above. This proposed 

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: 

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 and/or 

uncommanded opening of the NLG doors. 

There have been six cases reported on 

CL600–2B19 aircraft, one of which resulted 

in the collapse of the NLG at the departure 

gate. 

* * * * * 

The proposed AD would require actions 

that are intended to address the unsafe 

condition described in the MCAI. 

DATES: We must receive comments on 

this proposed AD by February 19, 2010.

Discussion 

Transport Canada Civil Aviation, 

which is the aviation authority for 

Canada, has issued Canadian 

Airworthiness Directive CF–2009–19, 

dated April 29, 2009 (referred to after 

this as ‘‘the MCAI’’), 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 and/or 

uncommanded opening of the NLG doors. 

There have been six cases reported on 

CL600–2B19 aircraft, one of which resulted 

in the collapse of the NLG at the departure 

gate. 

This directive mandates [an inspection of 

the NLG and NLG selector valves to 


srobinson on DSKHWCL6B1PROD with PROPOSALS
Federal Register / Vol. 75, No. 2 / Tuesday, January 5, 2010 / Proposed Rules 259 

determine the serial number and marking of 

the part and] a check [to determine the torque 

value and correct lockwire installation] of the 

[affected] 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. 

You may obtain further information 

by examining the MCAI in the AD 

docket. 

Relevant Service Information 

Bombardier has issued Service 

Bulletin 601R–32–104, dated March 3, 

2009. The actions described in this 

service information are intended to 

correct the unsafe condition identified 

in the MCAI. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with the State of 

Design Authority, we have been notified 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all pertinent 

information and determined an unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

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 proposed 

different actions in this AD from those 

in the MCAI in order to follow FAA 

policies. Any such differences are 

highlighted in a Note within the 

proposed AD. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 652 products of U.S. 

registry. We also estimate that it would 

take about 1 work-hour per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $80 per work-hour. Required 

parts would cost about $40 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 costs. 

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 the proposed AD on U.S. 

operators to be $78,240, or $120 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 proposed AD 

would not have federalism implications 

under Executive Order 13132. This 

proposed AD would 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 proposed regulation: 

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 proposed AD and placed it in the 

AD docket.

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above. This proposed 

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: It has been found the 

possibility of missing points of sealant 

application on the vapor barrier 

assembly in the wing stub rear box. In 

the event of fuel tank leak in this region 

associated with an unsealed vapor 

barrier assembly, migration of 

flammable vapors and fluids to middle 

electronic bay may occur, which then 

could lead to an uncontained fire event 

if the flammable vapors finds an 

ignition source. The proposed AD 

would require actions that are intended 

to address the unsafe condition 

described in the MCAI. 

DATES: We must receive comments on 

this proposed AD by February 19, 2010.
