Start Preamble

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:

There have been several Stick Pusher Capstan Shaft failures causing the dormant loss or severe degradation of the stick pusher function. * * *

Dormant loss or severe degradation of the stick pusher function could result in reduced controllability of the airplane. We are issuing this AD to require actions to correct the unsafe condition on these products.

DATES:

This AD becomes effective August 12, 2009.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of August 12, 2009.

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 23, 2009 (74 FR 8039). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states:

There have been several Stick Pusher Capstan Shaft failures causing the dormant loss or severe degradation of the stick pusher function. This directive is issued to revise the first flight of the day check [in the Airplane Flight Manual] of the stall protection system to detect a degradation of the stick pusher function. It also introduces a new periodic maintenance task [in the Airworthiness Limitations Section of the Instructions for Continuing Airworthiness] to check the structural integrity of the stick pusher capstan shaft.

Dormant loss or severe degradation of the stick pusher function could result in reduced controllability of the airplane. 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 707 products of U.S. registry. We also estimate that it will take about 1 work-hour per product to comply with the basic requirements of this AD. The average labor rate is $80 per work-hour. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $56,560, or $80 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 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://Start Printed Page 32412www.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.

Effective Date

(a) This airworthiness directive (AD) becomes effective August 12, 2009.

Affected ADs

(b) None.

Applicability

(c) This AD applies to the airplanes listed in Table 1 of this AD, certificated in any category.

Table 1—Applicability

Bombardier model—Serial Nos.—
CL-600-1A11 (CL-600) airplanes1004 through 1085 inclusive.
CL-600-2A12 (CL-601) airplanes3001 through 3066 inclusive.
CL-600-2B16 (CL-601-3A, CL-601-3R) airplanes5001 through 5194 inclusive.
CL-600-2B16 (CL-604) airplanes5301 thorough 5665 inclusive.

Note 1:

This AD requires revisions to certain operator maintenance documents to include new inspections. Compliance with these inspections is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by these inspections, the operator may not be able to accomplish the inspections described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (g)(1) of this AD. The request should include a description of changes to the required inspections that will ensure the continued operational safety of the airplane.

Subject

(d) Air Transport Association (ATA) of America Code 27: Flight Controls.

Reason

(e) The mandatory continuing airworthiness information (MCAI) states:

There have been several Stick Pusher Capstan Shaft failures causing the dormant loss or severe degradation of the stick pusher function. This directive is issued to revise the first flight of the day check [in the Airplane Flight Manual] of the stall protection system to detect a degradation of the stick pusher function. It also introduces a new periodic maintenance task [in the Airworthiness Limitations Section of the Instructions for Continuing Airworthiness] to check the structural integrity of the stick pusher capstan shaft.

Dormant loss or severe degradation of the stick pusher function could result in reduced controllability of the airplane.

Actions and Compliance

(f) Unless already done, do the following actions.

(1) Within 30 days after the effective date of this AD: Revise the Normal Procedures section of the applicable airplane flight manual (AFM) by inserting a copy of the applicable TR listed in Table 2 of this AD. Thereafter, operate the airplanes per the procedures specified in the applicable TR, except as provided by paragraph (g)(1) of this AD. If the operator has an AFM that is not listed in Table 2 of this AD, within 30 days after the effective date of this AD, revise the AFM using a method approved by the FAA or Transport Canada Civil Aviation (TCCA) (or its delegated agent).
