ACTION: Final rule; request for 

comments. 

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: 

Seven cases of on-ground hydraulic 

accumulator screw cap/end cap failure have 

been experienced on CL–600–2B19 

aeroplanes, resulting in the loss of the 

associated hydraulic system and high-energy 

impact damage to adjacent systems and 

structure. * * * 

* * * * * 

A detailed analysis of the calculated line 

of trajectory of a failed screw cap/end cap for 

each of the accumulators has been 

conducted, resulting in the identification of 

several areas where systems and/or structural 

components could potentially be damaged. 

Although all of the failures to date have 

occurred on the ground, an in-flight failure 

affecting such components could potentially 

have an adverse effect on the controllability 

of the aeroplane. 

* * * * * 

This AD requires actions that are 

intended to address the unsafe 

condition described in the MCAI. 

DATES: This AD becomes effective 

November 4, 2010. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of November 4, 2010.

SUPPLEMENTARY INFORMATION: 

Discussion 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian 

Airworthiness Directive CF–2010–24, 

dated August 3, 2010 (referred to after 

this as ‘‘the MCAI’’), to correct an unsafe 

condition for the specified products. 

The MCAI states: 

Seven cases of on-ground hydraulic 

accumulator screw cap/end cap failure have 

been experienced on CL–600–2B19 

aeroplanes, resulting in the loss of the 

associated hydraulic system and high-energy 

impact damage to adjacent systems and 

structure. The lowest number of flight cycles 

accumulated at the time of failure, to date, 

has been 6,991 flight cycles. 

The part numbers (P/N) of the 

accumulators currently installed on CL–600– 

2B19 aeroplanes are 601R75138–1 (08– 

60163–001 or 08–60163–002) [Hydraulic 

System No. 1, Hydraulic System No. 2, 

Inboard Brake and Outboard Brake 

accumulators] and 601R75138–3 (08–60164– 

001 or 08–60164–002) [Hydraulic System No. 

3 accumulator]. 

A detailed analysis of the calculated line 

of trajectory of a failed screw cap/end cap for 

each of the accumulators has been 

conducted, resulting in the identification of 

several areas where systems and/or structural 

components could potentially be damaged. 

Although all of the failures to date have 

occurred on the ground, an in-flight failure 

affecting such components could potentially 

have an adverse effect on the controllability 

of the aeroplane. 

This directive gives instructions to amend 

the Airplane Flight Manual (AFM), remove 

two accumulators (Hydraulic System No. 2 

and No. 3) from the aeroplane and conduct 

repetitive ultrasonic inspections [for cracks] 

of the Hydraulic System No. 1, Inboard Brake 

and Outboard Brake accumulators that are 

not identified by the letter ‘‘T’’ after the serial 

number (S/N) on the identification plate for 

cracks until they are replaced by new 

accumulators P/N 601R75139–1 (11093–4). 

Required actions also include 

deactivating the hydraulic system No. 3 

accumulator. You may obtain further 

information by examining the MCAI in 

the AD docket.

The actions described in this service 

information as outlined in the 

‘‘Discussion’’ section above, are intended 

to correct the unsafe condition 

identified in the MCAI. 

FAA’s Determination and Requirements 

of This 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 issuing this 

AD because we evaluated all pertinent 

information and determined the unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Differences Between the 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 FAA policies. 

Any such differences are highlighted in 

a NOTE within the AD. 

Explanation of Affected Accumulators 

The actions specified in the MCAI 

apply only to Tactair accumulators. 

Certain actions in this AD apply to all 

accumulators. This is a result of the 

unsafe condition, which is due to the 

location of the accumulators and 

potential damage resulting from the 

release of the accumulator screw cap/ 

end cap. This is the reason for the 

deactivation of the hydraulic system No. 

3 accumulator and removal of the 

hydraulic system No. 2 accumulator. 

Interim Action 

This AD does not require the removal 

of the hydraulic system No. 3 

accumulator, or replacement of the 

hydraulic system No. 1, inboard brake, 

and outboard brake accumulators, in 

Part IV and Part VII of the Canadian 

Airworthiness Directive CF–2010–24, 

dated August 3, 2010. The planned 

compliance time for the removal of the 

hydraulic system No. 3 accumulator, or 

replacement of the hydraulic system No. 

1, inboard brake, and outboard brake 

accumulators, in Part IV and Part VII of 

the Canadian Airworthiness Directive 

CF–2010–24, dated August 3, 2010, 

would allow enough time to provide 

notice and opportunity for prior public 

comment on the merits of those actions. 

Therefore, we are considering further 

rulemaking to address this issue. 

FAA’s Determination of the Effective 

Date 

An unsafe condition exists that 

requires the immediate adoption of this 

AD. The FAA has found that the risk to 

the flying public justifies waiving notice 

and comment prior to adoption of this 

rule because seven cases of on-ground 

hydraulic accumulator screw cap/end 

cap failure have been experienced on 

Model CL–600–2B19 airplanes, 

resulting in the loss of the associated 

hydraulic system and high-energy 

impact damage to adjacent systems and 

structure. The lowest number of flight 

cycles accumulated at the time of 

failure, to date, has been 6,991 flight 

cycles. 

A detailed analysis of the calculated 

line of trajectory of a failed screw cap/ 

end cap for each of the accumulators 

has been conducted, resulting in the 

identification of several areas where 

systems and/or structural components 

could potentially be damaged, fuel lines 

and wires included. Although all of the 

failures to date have occurred on the 

ground, an in-flight failure affecting 

such components could consequently 

reduce the controllability of the 

airplane. Therefore, we determined that 

notice and opportunity for public 

comment before issuing this AD are 

impracticable and that good cause exists 

for making this amendment effective in 

fewer than 30 days. 

Comments Invited 

This AD is a final rule that involves 

requirements affecting flight safety, and 

we did not precede it by notice and 

opportunity for public comment. We 

invite you to send any written relevant 

data, views, or arguments about this AD. 

Send your comments to an address 

listed under the ADDRESSES section. 

Include ‘‘Docket No. FAA–2010–1037; 

Directorate Identifier 2010–NM–202– 

AD’’ at the beginning of your comments. 

We specifically invite comments on the 

overall regulatory, economic, 

environmental, and energy aspects of 

this AD. We will consider all comments 

received by the closing date and may 

amend this AD because of those 

comments. 

We will post all comments we 

receive, without change, to http:// 

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact we receive 

about this AD. 

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

FAA AD Differences 

Note 3: This AD differs from the

follows: 

(1) This AD does not require the 

removal of the hydraulic system No. 3 

accumulator, or replacement of the 

hydraulic system No. 1, inboard brake, 

and outboard brake accumulators, in 

Part IV and Part VII of the Canadian 

Airworthiness Directive CF–2010–24, 

dated August 3, 2010. 

(2) The actions specified in Canadian 

Airworthiness Directive CF–2010–24, 

dated August 3, 2010, apply only to 

Tactair accumulators. The actions 

required by paragraphs (h) and (i) of this 

AD apply to all accumulators in the 

positions specified in paragraphs (h) 

and (i) of this AD. 

Other FAA AD Provisions 

(s) The following provisions also 

apply to this AD: 

(1) Alternative Methods of 

Compliance (AMOCs): The Manager, 

New York Aircraft Certification Office 

(ACO), ANE–170, FAA, has the 

authority to approve AMOCs for this 

AD, if requested using the procedures 

found in 14 CFR 39.19. Send 

information to ATTN: Program Manager,

on any airplane to which the AMOC 

applies, notify your principal 

maintenance inspector (PMI) or 

principal avionics inspector (PAI), as 

appropriate, or lacking a principal 

inspector, your local Flight Standards 

District Office. The AMOC approval 

letter must specifically reference this 

AD. 

(2) Airworthy Product: For any 

requirement in this AD to obtain 

corrective actions from a manufacturer 

or other source, use these actions if they 

are FAA-approved. Corrective actions 

are considered FAA-approved if they 

are approved by the State of Design 

Authority (or their delegated agent). You 

are required to assure the product is 

airworthy before it is returned to 

service. 

(3) Reporting Requirements: For any 

reporting requirement in this AD, under 

the provisions of the Paperwork 

Reduction Act (44 U.S.C. 3501 et seq.), 

the Office of Management and Budget
