AGENCY:

Federal Aviation Administration (FAA), Department of Transportation (DOT).

ACTION:

Final rule.

SUMMARY:

We are superseding Airworthiness Directive (AD) 2005-15-04 for certain Bombardier, Inc. Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 Variants) airplanes. AD 2005-15-04 required operators to assign serial numbers or part numbers to certain landing gear parts; establish the number of landings on the parts, if necessary; and revise the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness (ICA) to reflect the new life limits of the landing gear parts. This new AD adds airplanes to the applicability, requires operators to assign serial numbers or part numbers to certain additional landing gear parts to establish the number of landings on the parts if necessary, and requires operators to record in all required airplane technical records and manuals the new part numbers, serial numbers, and landings assigned to these parts. This AD was prompted by reports that landing gear parts that have safe-life limits but do not have serial numbers or part numbers can be removed from one landing gear and re-installed on another, making tracking difficult. We are issuing this AD to prevent life-limited landing gear parts from being used beyond their safe-life limits, which could lead to collapse of the landing gear.

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2005-15-04, Amendment 39-14193 (70 FR 43032, July 26, 2005). AD 2005-15-04 applied to certain Bombardier, Inc. Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 Variants) airplanes. The NPRM published in the Federal Register on December 30, 2013 (78 FR 79329). The NPRM was prompted by reports that landing gear parts that have safe-life limits but do not have serial numbers or part numbers can be removed from one landing gear and re-installed on another, making tracking difficult. The NPRM proposed to add airplanes to the applicability, require operators to assign serial numbers or part numbers to certain additional landing gear parts to establish the number of landings on the parts if necessary, and requires operators to record in all required airplane technical records and manuals the new part numbers, serial numbers, and landings assigned to these parts. We are issuing this AD to prevent life-limited landing gear parts from being used beyond their safe-life limits, which could lead to collapse of the landing gear.

Transport Canada Civil Aviation (TCCA), which is the airworthiness authority for Canada, has issued Canadian Airworthiness Directives CF-2003-18R2, dated September 28, 2011; CF-2003-20R1, dated September 28, 2011; and CF-2003-21R2, dated September 28, 2011 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”); to correct an unsafe condition for certain Bombardier, Inc. Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 Variants) airplanes. The MCAI states:

Certain landing gear parts that are listed in the aeroplane model Airworthiness Limitations Section, as safe life items with structural life limits, could be rotable and may not have been serialized, making tracking difficult. This [Canadian airworthiness] directive mandates that such parts be serialized. This [Canadian airworthiness] directive also provides the procedure to determine the number of landings for those parts where the service history cannot be established.

* * * * *

[T]his [Canadian Airworthiness] directive * * * mandate[s] serialization of * * * additional landing gear parts.

This AD also adds airplanes to the applicability. The unsafe condition is using life-limited landing gear parts beyond their safe-life limits, which could lead to collapse of the landing gear. You may examine the MCAI in the Start Printed Page 49435AD docket on the Internet at http://www.regulations.gov/​#!documentDetail;​D=​FAA-2013-1065-0002.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (78 FR 79329, December 30, 2013) or on the determination of the cost to the public.

“Contacting the Manufacturer” Paragraph in This AD

Since late 2006, we have included a standard paragraph titled “Airworthy Product” in all MCAI ADs in which the FAA develops an AD based on a foreign authority's AD.

We have become aware that some operators have misunderstood or misinterpreted the Airworthy Product paragraph to allow the owner/operator to use messages provided by the manufacturer as approval of deviations during the accomplishment of an AD-mandated action. The Airworthy Product paragraph does not approve messages or other information provided by the manufacturer for deviations to the requirements of the AD-mandated actions. The Airworthy Product paragraph only addresses the requirement to contact the manufacturer for corrective actions for the identified unsafe condition and does not cover deviations from other AD requirements. However, deviations to AD-required actions are addressed in 14 CFR 39.17, and anyone may request the approval for an alternative method of compliance to the AD-required actions using the procedures found in 14 CFR 39.19.

To address this misunderstanding and misinterpretation of the Airworthy Product paragraph, we have changed the paragraph and retitled it “Contacting the Manufacturer.” This paragraph now clarifies that for any requirement in this AD to obtain corrective actions from a manufacturer, the actions must be accomplished using a method approved by the FAA, Transport Canada Civil Aviation (TCCA), or Bombardier's TCCA Design Approval Organization (DAO).

The Contacting the Manufacturer paragraph also clarifies that, if approved by the DAO, the approval must include the DAO-authorized signature. The DAO signature indicates that the data and information contained in the document are TCCA-approved, which is also FAA-approved. Messages and other information provided by the manufacturer that do not contain the DAO-authorized signature approval are not TCCA-approved, unless TCCA directly approves the manufacturer's message or other information.

This clarification does not remove flexibility previously afforded by the Airworthy Product paragraph. Consistent with long-standing FAA policy, such flexibility was never intended for required actions. This is also consistent with the recommendation of the Airworthiness Directive Implementation Aviation Rulemaking Committee to increase flexibility in complying with ADs by identifying those actions in manufacturers' service instructions that are “Required for Compliance” with ADs. We continue to work with manufacturers to implement this recommendation. But once we determine that an action is required, any deviation from the requirement must be approved as an alternative method of compliance.

We also have decided not to include a generic reference to either the “delegated agent” or “design approval holder (DAH) with State of Design Authority design organization approval,” but instead we have provided the specific delegation approval granted by the State of Design Authority for the DAH throughout this AD.

Conclusion

We reviewed the available data and determined that air safety and the public interest require adopting this AD with the changes described previously and minor editorial changes. We have determined that these minor changes:

  • Are consistent with the intent that was proposed in the NPRM (78 FR 79329, December 30, 2013) for correcting the unsafe condition; and
  • Do not add any additional burden upon the public than was already proposed in the NPRM (78 FR 79329, December 30, 2013).

We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD.

Costs of Compliance

We estimate that this AD affects 419 airplanes of U.S. registry.

The actions that were required by AD 2005-15-04, Amendment 39-14193 (70 FR 43032, July 26, 2005), that are retained in this AD take up to 13 work-hours 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 up to $1,105 per product.

We estimate that it would take about 9 work-hours per product to comply with the new basic requirements of this AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this AD on U.S. operators to be $320,535, or $765 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 that 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);

3. Will not affect intrastate aviation in Alaska; and

4. 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.

End Amendment Part

2014-15-13 Bombardier, Inc.: Amendment 39-17915. Docket No. FAA-2013-1065; Directorate Identifier 2011-NM-230-AD.

(a) Effective Date

This AD becomes effective September 25, 2014.

(b) Affected ADs

This AD replaces AD 2005-15-04, Amendment 39-14193 (70 FR 43032, July 26, 2005).

(c) Applicability

This AD applies to Bombardier, Inc. airplanes, certificated in any category, as identified in paragraphs (c)(1) through (c)(4) of this AD.

(1) Model CL-600-1A11 (CL-600) airplanes, serial numbers 1004 through 1085 inclusive.

(2) Model CL-600-2A12 (CL-601) airplanes, serial numbers 3001 through 3066 inclusive;

(3) Model CL-600-2B16 (CL-601-3A and CL-601-3R Variants) airplanes, serial numbers 5001 through 5194 inclusive.

(4) Model CL-600-2B16 (CL-604 Variant) airplanes, serial numbers 5301 through 5573 inclusive, 5579, and 5595.

(5) This AD requires revisions to certain operator maintenance documents to include new actions (e.g., inspections). Compliance with these actions is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by this AD, the operator may not be able to accomplish the actions 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 (r) of this AD. The request should include a description of changes to the required actions that will ensure the continued damage tolerance of the affected structure.

(d) Subject

Air Transport Association (ATA) of America Code 32, Landing Gear.

(e) Reason

This AD was prompted by reports that landing gear parts that have safe-life limits but do not have serial numbers (S/Ns) or part numbers (P/Ns) can be removed from one landing gear and re-installed on another, making tracking difficult. We are issuing this AD to prevent life-limited landing gear parts from being used beyond their safe-life limits, which could lead to collapse of the landing gear.

(f) Compliance

Comply with this AD within the compliance times specified, unless already done.

(g) Retained Requirement To Add S/Ns orP/Ns

This paragraph restates the actions required by paragraph (f) of AD 2005-15-04, Amendment 39-14193 (70 FR 43032, July 26, 2005), with revised affected airplanes. Except for Model CL-600-2B16 airplanes having S/Ns 5514 through 5595 inclusive: At the applicable compliance time specified in paragraph (g)(1), (g)(2), or (g)(3) of this AD, add serial numbers and part numbers, as applicable, to the parts identified in the applicable service bulletin specified in paragraph (g)(1), (g)(2), or (g)(3) of this AD. Do all actions in accordance with the applicable service bulletin specified in paragraph (g)(1), (g)(2), or (g)(3) of this AD.

(j) Retained Parts Installation Limitation

This paragraph restates the limitations specified in paragraph (i) of AD 2005-15-04, Amendment 39-14193 (70 FR 43032, July 26, 2005), with revised affected airplanes. Except for Model CL-600-2B16 airplanes having serial numbers 5514 through 5595 inclusive: As of August 30, 2005 (the effective date of AD 2005-15-04), no person may install on any airplane a landing gear part, unless it has had the applicable part number or serial number added in accordance with paragraph (g) of this AD; and has had the number of landings established in accordance with paragraph (h) of this AD.

(k) Retained Stipulation of Information of No Reporting

This paragraph restates the stipulation specified in paragraph (j) of AD 2005-15-04, Amendment 39-14193 (70 FR 43032, July 26, 2005). Although the service bulletins identified in paragraph (g) of this AD specify that operators should submit incorporation notices to Bombardier after each new part number or serial number and landings assigned to these parts is added, this AD does not include that action.
