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: 

During maintenance at the vendor’s 

facility, some HSTAs [horizontal stabilizer 

trim actuators] were assembled with the 

incorrect load bearing balls. The material of 

these discrepant balls has lower wear 

characteristics and as such, has a shorter 

expected life. If not corrected, this condition 

can result in the HSTA jam leading to 

difficulties in controlling the aircraft. 

* * * * * 

The unsafe condition is possible loss of 

controllability of the airplane. This AD 

requires actions that are intended to 

address the unsafe condition described 

in the MCAI. 

DATES: This AD becomes effective 

September 17, 2010. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of September 17, 2010. 

We must receive comments on this 

AD by October 18, 2010.

SUPPLEMENTARY INFORMATION: 

Discussion 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian 

Airworthiness Directive CF–2010–20, 

dated July 19, 2010 (referred to after this 

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

condition for the specified products. 

The MCAI states: 

During maintenance at the vendor’s 

facility, some HSTAs were assembled with 

the incorrect load bearing balls. The material 

of these discrepant balls has lower wear 

characteristics and as such, has a shorter 

expected life. If not corrected, this condition 

can result in the HSTA jam leading to 

difficulties in controlling the aircraft. 

This directive mandates incorporation of 

the HSTA with the correct load bearing balls. 

The unsafe condition is possible loss of 

controllability of the airplane. The 

corrective action requires inspecting to 

determine the serial number of the 

HSTAs. You may obtain further 

information by examining the MCAI in 

the AD docket. 


emcdonald on DSK2BSOYB1PROD with RULES
53850 Federal Register / Vol. 75, No. 170 / Thursday, September 2, 2010 / Rules and Regulations 

Relevant Service Information 

Bombardier has issued Service 

Bulletin 670BA–27–057, dated June 14, 

2010. 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 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. 

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 some HSTAs were 

assembled with load bearing balls that 

have lower wear characteristics and a 

shorter life expectancy. If not corrected, 

this condition can result in the HSTA 

jam leading to difficulties in controlling 

the airplane. The unsafe condition is 

possible loss of 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–2010–0851; 

Directorate Identifier 2010–NM–171– 

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 

Flexibility Act. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this AD and placed it in the AD docket.

Actions 

(g) Within 500 flight cycles after the 

effective date of this AD: Inspect HSTAs 

having P/Ns 8489–7 and 8489–7R to 

determine if the serial numbers (S/Ns) 

identified in paragraph 1.A., ‘‘Effectivity,’’ of 

Bombardier Service Bulletin 670BA–27–057, 

dated June 14, 2010, are installed. A review 

of airplane maintenance records is acceptable 

in lieu of this inspection if the serial number 

of the HSTA can be conclusively determined 

from that review. 

(1) For any HSTA with a serial number that 

is not identified in paragraph 1.A., 

‘‘Effectivity,’’ of Bombardier Service Bulletin 

670BA–27–057, dated June 14, 2010: No 

further action is required by paragraph (g) of 

this AD. 

(2) For any HSTA with a serial number that 

is identified in paragraph 1.A., ‘‘Effectivity,’’ 

of Bombardier Service Bulletin 670BA–27– 

057, dated June 14, 2010: Replace the HSTA 

with a serviceable HSTA, in accordance with 

the Accomplishment Instructions of 

Bombardier Service Bulletin 670BA–27–057, 

dated June 14, 2010, at the applicable time 

specified by paragraph (g)(2)(i), (g)(2)(ii), 

(g)(2)(iii), or (g)(2)(iv) of this AD. 

Note 1: Bombardier Service Bulletin 

670BA–27–057, dated June 14, 2010, 

references Sagem SA Service Bulletin 8489– 

27–006, dated December 8, 2009, as an 

additional source of guidance for modifying 

the HSTA. Sagem SA Service Bulletin 8489– 

27–006, dated December 8, 2009, references 

Ratier-Figeac Service Bulletin RF–DSC–075– 

07, Version 03, dated November 10, 2009, as 

an additional source of guidance for 

modifying the HSTA. The suffix ‘‘A’’ after the 

serial number indicates serviceable HSTAs 

that have been modified. 

(i) For any HSTA that has accumulated less 

than or equal to 8,000 flight cycles as of the 

effective date of this AD: Before the HSTA 

accumulates 10,000 flight cycles. 

(ii) For any HSTA that has accumulated 

more than 8,000 flight cycles but less than or 

equal to 10,000 flight cycles as of the 

effective date of this AD: Before the HSTA 

accumulates an additional 2,000 flight cycles, 

but no later than 11,000 flight cycles on the 

HSTA. 

(iii) For any HSTA that has accumulated 

more than 10,000 flight cycles but less than 

or equal to 12,000 flight cycles as of the 

effective date of this AD: Before the HSTA 

accumulates an additional 1,000 flight cycles, 

but no later than 12,500 flight cycles on the 

HSTA. 

(iv) For any HSTAs that has accumulated 

more than 12,000 flight cycles as of the 

effective date of this AD: Before the HSTA 

accumulates an additional 500 flight cycles. 

(h) As of the effective date of this AD, no 

person may install an HSTA, having P/N 

8489–7 or 8489–7R, with a serial number 

identified in paragraph 1.A., ‘‘Effectivity,’’ of 

Bombardier Service Bulletin 670BA–27–057, 

dated June 14, 2010, on any airplane. 

FAA AD Differences 

Note 2: This AD differs from the MCAI 

and/or service information as follows: 

Canadian Airworthiness Directive CF–2010– 

20, dated July 19, 2010, refers to an incorrect 

date of April 28, 2010, for Bombardier 

Service Bulletin 670BA–27–057. The correct 

date for Bombardier Service Bulletin 670BA– 

27–057 is June 14, 2010.

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: 

During testing, it was discovered that when 

the outflow valve (OFV) manual mode 

connector is not connected, the manual mode 

motor and altitude limitation are not 

properly tested. Consequently, a disconnect 

of the OFV manual mode and/or a related 

wiring failure could potentially result in a 

dormant loss of several CPC [cabin pressure 

control] backup/safety functions, including 

OFV manual control, altitude limitation, 

emergency depressurization and smoke 

clearance. * * * 

* * * * * 

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.
