[Federal Register Volume 83, Number 190 (Monday, October 1, 2018)] [Proposed Rules] [Pages 49317-49322] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2018-20950] ======================================================================= ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2018-0801; Product Identifier 2017-NM-147-AD] RIN 2120-AA64 Airworthiness Directives; Bombardier, Inc., Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: We propose to supersede Airworthiness Directive (AD) 2008-24- 14, which applies to all Bombardier, Inc., Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. AD 2008-24-14 requires revising the instructions for continued airworthiness to incorporate certain airworthiness limitations for the main landing gear (MLG) trunnion fitting assembly. Since we issued AD 2008-24-14, new airworthiness limitation (AWL) tasks have been introduced with revised inspection, modification, and safe-life requirements. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate certain AWLs. It would also require reworking the trunnion fitting in order to meet new structural safe-life limits. We are proposing this AD to address the unsafe condition on these products. DATES: We must receive comments on this proposed AD by November 15, 2018.

We will also post a report summarizing each [[Page 49318]] substantive verbal contact we receive about this proposed AD. Discussion We issued AD 2008-24-14, Amendment 39-15758 (73 FR 73785, December 4, 2008) (``AD 2008-24-14''), for all Bombardier, Inc., Model CL-600- 2B19 (Regional Jet Series 100 & 440) airplanes. AD 2008-24-14 requires revising the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness to incorporate new structural inspection requirements. AD 2008-24-14 resulted from reports of the discovery of cracks on the MLG trunnion fitting web during fatigue testing. We issued AD 2008-24-14 to detect and correct fatigue cracking of the MLG trunnion fitting web. Actions Since AD 2008-24-14 Was Issued Since we issued AD 2008-24-14, new AWL tasks have been introduced with revised inspection, modification, and safe-life requirements, and we have determined that the trunnion fitting lower flange and both forward and aft bore holes are also subject to fatigue cracking. Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF- 2017-27, dated August 2, 2017 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for certain Bombardier, Inc., Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. The MCAI states: Cracks on the main landing gear (MLG) trunnion fitting web discovered during fatigue testing led to the issuance of [Canadian] AD CF-2008-21 [which corresponds to FAA AD 2008-24-14], which mandated new inspection requirements to ensure that fatigue cracking of the trunnion web would be detected and corrected. Additional fatigue test article findings and in-service findings have shown that the trunnion fitting lower flange and both forward and aft bore holes are also subject to fatigue cracking. Failure of the main landing gear trunnion fitting could result in the collapse of the main landing gear. Bombardier Inc. has decided to implement a series of design changes to improve the fatigue life of the trunnion fitting that is now a safe-life assembly. New and revised Airworthiness Limitation (AWL) tasks for the MLG trunnion fitting assembly have been introduced in order to require new inspection, modification, and safe-life requirements. This [Canadian] AD mandates the incorporation of these new and revised AWL tasks, and removal of the AWL tasks they replace, to ensure that fatigue cracking of the MLG trunnion fitting is detected and corrected. This [Canadian] AD also requires rework of the trunnion fitting in order to meet new structural safe-life limits. You may examine the MCAI in the AD docket on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2018- 0801. Related Service Information Under 1 CFR Part 51 Bombardier has issued the following service information. Bombardier Service Bulletin 601R-57-046, Revision C, dated December 20, 2012, describes the cold working of fastener holes in the MLG trunnion fitting, and related investigative and corrective actions. Bombardier Service Bulletin 601R-57-047, Revision B, dated October 2, 2012, describes the installation of forcemate bushings in the MLG trunnion, and related investigative and corrective actions. Bombardier Service Bulletin 601R-57-048, Revision C, dated June 6, 2013, describes the cold working of holes on the web of the MLG trunnion, and related investigative and corrective actions. These documents are distinct because they apply to different parts of the airplane. The following service information describes certain AWL tasks for the MLG trunnion fitting assembly. Bombardier Maintenance Requirements Manual Temporary Revision (TR) 2B-2237, dated June 19, 2014. Bombardier Maintenance Requirements Manual Temporary Revision (TR) 2B-2238, dated June 19, 2014. Bombardier Maintenance Requirements Manual Temporary Revision (TR) 2B-2239, dated June 19, 2014. Bombardier Maintenance Requirements Manual Temporary Revision (TR) 2B-2241, dated June 19, 2014. Bombardier Maintenance Requirements Manual Temporary Revision (TR) 2B-2242, dated June 19, 2014. Bombardier Maintenance Requirements Manual Temporary Revision (TR) 2B-2246, dated November 7, 2014. These documents are distinct because they describe different actions. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section. FAA's Determination and Requirements of This Proposed 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 proposing 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. This proposed AD would require 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 proposed 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 (p)(1) of this proposed AD. The request should include a description of changes to the required actions that will ensure the continued operational safety of the airplane. Differences Between This Proposed AD and the Service Information The MCAI includes the following statement: ``If it is not possible to complete all of the instructions in the SBs . . . due to the configuration of the aircraft, contact Bombardier Inc. for approved instructions.'' This issue is addressed in 14 CFR 39.17, which states that ``If a change in a product affects your ability to accomplish the actions required by the AD in any way, you must request FAA approval of an AMOC [alternative method of compliance]. . . .'' Since we do not currently have the authority to delegate AMOC approvals to foreign civil aviation authorities, the FAA is responsible for these approvals. Costs of Compliance We estimate that this proposed AD affects 460 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: [[Page 49319]] Estimated Costs ---------------------------------------------------------------------------------------------------------------- Action Labor cost Parts cost Cost per product Cost on U.S. operators ---------------------------------------------------------------------------------------------------------------- Retained actions.............. 1 work-hour x $0 >$85 $39,100. $85 per hour = $85. Rework trunnion bearings (new Up to 178 work- 38,928 Up to $54,058... Up to $24,866,680. proposed actions). hours x $85 per hour = Up to $15,130. ---------------------------------------------------------------------------------------------------------------- We have determined that revising the maintenance or inspection program takes an average of 90 work-hours per operator, although we recognize that this number may vary from operator to operator. In the past, we have estimated that this action takes 1 work-hour per airplane. Since operators incorporate maintenance or inspection program changes for their affected fleet(s), we have determined that a per- operator estimate is more accurate than a per-airplane estimate. Therefore, we estimate the total cost per operator to be $7,650 (90 work-hours x $85 per work-hour). We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this proposed AD. According to the manufacturer, some or all of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. 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. This proposed AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes to the Director of the System Oversight Division. Regulatory Findings We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 proposed 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), 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39--AIRWORTHINESS DIRECTIVES 0 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. Sec. 39.13 [Amended] 0 2. The FAA amends Sec. 39.13 by removing Airworthiness Directive (AD) 2008-24-14, Amendment 39-15758 (73 FR 73785, December 4, 2008), and adding the following new AD: Bombardier, Inc.: Docket No. FAA-2018-0801; Product Identifier 2017- NM-147-AD. (a) Comments Due Date We must receive comments by November 15, 2018. (b) Affected ADs This AD replaces AD 2008-24-14, Amendment 39-15758 (73 FR 73785, December 4, 2008) (``AD 2008-24-14''). (c) Applicability This AD applies to Bombardier, Inc., Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes, certificated in any category, serial numbers 7002 and subsequent. (d) Subject Air Transport Association (ATA) of America Code 57, Wings. (e) Reason This AD was prompted by reports of cracks on the main landing gear trunnion (MLG) fitting during fatigue testing, the introduction of new airworthiness limitation (AWL) tasks with revised inspection, modification, and safe-life requirements, and a determination that the trunnion fitting lower flange and both forward and aft bore holes are also subject to fatigue cracking. We are issuing this AD to detect and correct fatigue cracking of the MLG trunnion fitting. Failure of the MLG trunnion fitting web could compromise the structural integrity of the trunnion fitting and result in MLG collapse. (f) Compliance Comply with this AD within the compliance times specified, unless already done.
