E8-26911. Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) Airplanes

AGENCY:

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

ACTION:

Final rule; request for comments.

SUMMARY:

The FAA is superseding an existing airworthiness directive (AD) that applies to certain Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. The existing AD currently requires inspecting to identify the wing anti-ice ducts (piccolo tubes) in the wing leading edge. For airplanes with affected piccolo tubes, the existing AD requires revising the airplane flight manual (AFM) to introduce new procedures for operation in icing conditions. The existing AD provides an optional implementation of repetitive inspections for cracks of affected piccolo tubes, and corrective actions if necessary, which terminates the operational limitations. The existing AD also provides an optional installation of certain new piccolo tubes, which terminates both the AFM revision and the inspections. This AD adds airplanes to the applicability, requires revising the AFM to introduce new procedures for operation in icing conditions, and requires inspecting to determine if certain anti-ice piccolo ducts are installed, and replacing or repairing the piccolo duct if necessary. This AD also provides an optional terminating action of replacing all affected piccolo ducts. This AD results from reports of failed piccolo tubes. We are issuing this AD to prevent cracked piccolo tubes, which could result in air leakage, a possible adverse effect on the anti-ice air distribution pattern and anti-ice capability without annunciation to the flight crew, and consequent reduced controllability of the airplane.

DATES:

This AD becomes effective December 1, 2008.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of December 1, 2008.

On September 7, 2005 (70 FR 49164, August 23, 2005), the Director of the Federal Register approved the incorporation by reference of certain other publications listed in the AD.

We must receive any comments on this AD by December 15, 2008.

SUPPLEMENTARY INFORMATION:

Discussion

On August 11, 2005, the FAA issued AD 2005-17-12, amendment 39-14223 (70 FR 49164, August 23, 2005). That AD applies to certain Bombardier Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. That AD requires inspecting to identify the wing anti-ice ducts (piccolo tubes) in the wing leading edge. For airplanes with affected piccolo tubes, that AD requires revising the airplane flight manual (AFM) to introduce new procedures for operation in icing conditions. That AD provides an optional implementation of repetitive inspections for cracks of affected piccolo tubes, and corrective actions if necessary, which terminates the operational limitations. That AD also provides an optional installation of certain new piccolo tubes, which terminates both the AFM revision and the inspections. That AD resulted from reports of failed piccolo tubes. The actions specified in that AD are intended to prevent cracked piccolo tubes, which could result in air leakage, a possible adverse effect on the anti-ice air distribution pattern and anti-ice capability without annunciation to the flight crew, and consequent reduced controllability of the airplane.

Actions Since AD Was Issued

Since we issued AD 2005-17-12, we received a report that faulty piccolo tubes might have been installed in a number of leading edge assemblies built as spares, and whose current locations are not specifically known. These faulty parts may have been installed on airplanes affected by that AD. Faulty piccolo tubes could crack, which could result in air leakage, a possible adverse effect on the anti-ice air distribution pattern and anti-ice capability without annunciation to the flight crew, and consequent reduced controllability of the airplane.

Relevant Service Information

Bombardier has issued Canadair Temporary Revision RJ/155-6, dated September 17, 2008 (“the TR”), to the Canadair Regional Jet AFM, CSP A-012. The TR describes new procedures for operation in icing conditions and supersedes Canadair TR RJ/155, dated July 5, 2005 (which we referred to as the appropriate source of service information for doing the AFM revision required by AD 2005-17-12).

Bombardier has also issued Service Bulletin 601R-30-029, Revision B, dated August 29, 2005. We referred to Bombardier Service Bulletin 601R-30-029, Revision A, dated July 7, 2005, as the appropriate source of service information for doing certain actions required by AD 2005-17-12. Revision B contains the same procedures as Revision A but adds airplanes to the effectivity and removes certain other airplanes from the effectivity.

Bombardier has also issued Alert Service Bulletin A601R-30-032, dated September 18, 2008. This service bulletin supersedes Bombardier Service Bulletin 601R-30-029, Revision A, dated July 7, 2005. Bombardier Alert Service Bulletin A601R-30-032 describes procedures for inspecting to determine if certain anti-ice piccolo ducts are installed, and replacing or repairing the piccolo duct if necessary.

Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition. Transport Canada Civil Aviation (TCCA) mandated the service information and issued Canadian airworthiness directive CF-2008-30, dated October 7, 2008 (referred to after this as “the MCAI”), to ensure the continued airworthiness of these airplanes in Canada. Canadian airworthiness directive CF-2008-30 supersedes Canadian airworthiness directive CF-2005-26R1, dated September 21, 2005, and adds airplanes to the applicability. We referred to Canadian airworthiness directive CF-2005-26, dated July 11, 2005, in our AD 2005-17-12.

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 an unsafe condition exists and is likely to exist or develop on other products of the same type design.

Therefore, we are issuing this AD to supersede AD 2005-17-12. This new AD retains certain requirements of the existing AD. This AD also requires accomplishing the actions specified in the service information described previously, except as discussed under “Differences Between the AD and the Service Information.” This AD also adds airplanes to the applicability and removes certain other airplanes from the applicability.

Differences Between the AD and the Service Information

Where Bombardier Alert Service Bulletin A601R-30-032, dated September 18, 2008, specifies that Bombardier may be contacted for information regarding repair, this AD requires repair according to a method approved by either the Manager, New York ACO, or TCCA (or its delegated agent).

Interim Action

We consider this AD interim action. We are currently considering requiring the replacement of all piccolo ducts that have serial numbers identified in Part A, Paragraph 2.A., of the Accomplishment Instructions of Bombardier Alert Service Bulletin A601R-30-032, dated September 18, 2008, with piccolo ducts that do not have the affected serial numbers, which will constitute terminating action for the actions required by this AD. However, the planned compliance time for the replacement would allow enough time to provide notice and opportunity for prior public comment on the merits of the replacement.

FAA's Justification and Determination of the Effective Date

Because of our requirement to promote safe flight of civil aircraft and thus, the critical need to ensure proper functioning of the anti-ice systems during the upcoming winter season, and the short compliance time involved with this action, this AD must be issued immediately.

Because an unsafe condition exists that requires the immediate adoption of this AD, we find that notice and opportunity for prior public comment hereon are impracticable and that good cause exists for making this amendment effective in less than 30 days.

Comments Invited

This AD is a final rule that involves requirements affecting flight safety, and we did not provide you with notice and an opportunity to provide your comments before it becomes effective. However, we invite you to send any written data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include “Docket No. FAA-2008-1200; Directorate Identifier 2008-NM-178-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 have 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 the 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 AD and placed it in the AD docket. See the ADDRESSES section for a location to examine the regulatory evaluation.
