[Federal Register Volume 81, Number 12 (Wednesday, January 20, 2016)] [Proposed Rules] [Pages 3038-3042] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2016-00698] ======================================================================= ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2015-8471; Directorate Identifier 2013-NM-153-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) 2010-23- 19, that applies to certain Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701, and 702) airplanes, Model CL-600-2D15 (Regional Jet Series 705) airplanes, and Model CL-600-2D24 (Regional Jet Series 900) airplanes. AD 2010-23-19 requires repetitive inspections for damage of the main landing gear (MLG) inboard doors and fairing, and corrective actions if necessary. Since we issued AD 2010- 23-19, we have received reports of the MLG failing to fully extend. This proposed AD would require repetitive inspections for damage of the MLG inboard doors, MLG fairing, and adjacent structures of the MLG inboard doors, and corrective actions if necessary; replacement of the MLG fairing seal; and a terminating action involving increasing the clearances between the MLG fairing and MLG door. This proposed AD would also add one airplane and remove others from the applicability. We are proposing this AD to prevent loss of controllability of the airplane during landing. DATES: We must receive comments on this proposed AD by March 7, 2016. ADDRESSES: You may send comments by any of the following methods:Federal eRulemaking Portal: Go to http://www.regulations.gov.

Discussion On November 1, 2010, we issued AD 2010-23-19, Amendment 39-16508 (75 FR 68695, November 9, 2010). AD 2010-23-19 requires actions intended to address an unsafe condition on certain Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701, and 702) airplanes, Model CL-600-2D15 (Regional Jet Series 705) airplanes, and Model CL- 600-2D24 (Regional Jet Series 900) airplanes. Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Airworthiness Directive CF-2010-36R1, dated July 18, 2013 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for the specified products. The MCAI states: Two cases of main landing gear (MLG) failure to fully extend have been reported. An MLG failing to extend may result in an unsafe asymmetric landing configuration. Preliminary investigation has shown that interference between the MLG door and the MLG fairing seal prevented the MLG door from opening. This [Canadian] AD mandates the [detailed] inspection [for damage] and rectification [corrective action], as required, of the MLG fairing and seal, MLG door, and adjacent structures. Data collected from the Original Issue of this [Canadian] AD shows potential deficiencies with the inspection. This [Canadian] AD is revised to update the applicability section and to introduce additional mitigating actions and the terminating action [a modification that includes related investigative actions, and corrective action if necessary]. The unsafe condition is the loss of controllability of the airplane during landing. Damage includes the following: For the MLG fairing seal: Cracks, cuts, or tears in the material of the MLG fairing seal, and cuts in the material base. For the MLG inboard doors: Missing or broken rollers on the MLG inboard door, missing stops, loose or missing fasteners from the stops, and damage (including, but not limited to, corrosion, cracking, and dents) along the edge of the MLG inboard door adjacent to the MLG fairing. For the MLG fairing: Missing forward and aft stops, loose or missing fasteners from the forward and aft stops, and damage (including, but not limited to, corrosion, cracking, and dents) along the edge of the MLG fairing adjacent to the MLG inboard door. For the stops and wedges on the forward and aft spars: Missing stops, loose or missing fasteners from the stops, missing wedges, and loose or missing fasteners from the wedges. Corrective actions include replacement of MLG fairing seals, and increasing the clearances between the MLG fairing and MLG door. The terminating modification involves increasing the clearance between the left and right MLG fairings and the left and right MLG doors. Related investigative actions for the terminating modification include the following inspections: A detailed inspection of the MLG fairing for missing forward and aft stops, loose or missing fasteners from the forward and aft stops, and damage along the edge of the MLG fairing adjacent to the MLG inboard door. A detailed visual inspection of the MLG inboard door for missing or broken rollers on the MLG inboard door, missing stops, loose or missing fasteners from the stops, and damage along the edge of the MLG inboard door adjacent to the MLG fairing. A detailed visual inspection on the stops and wedge on the forward and aft spars for missing stops, loose or missing fasteners from the stops, missing wedges, and loose or missing fasteners from the wedges. A liquid penetrant inspection or an eddy current inspection for cracks in the aft stop-fitting and stiffener of the forward member of the MLG inboard door. 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-2015- 8471. Related Service Information Under 1 CFR Part 51 Bombardier, Inc. has issued Alert Service Bulletin A670BA-32-030, Revision D, dated August 6, 2013, which describes procedures for an inspection of the MLG inboard doors, MLG fairing, and adjacent structure of the MLG inboard doors. This service bulletin also describes procedures for replacement of damaged MLG fairing seal(s) and for a clearance check of the MLG door or, if necessary, for removing and/or installing a MLG door. Bombardier, Inc. has also issued Bombardier Service Bulletin 670BA- 32-040, Revision E, dated November 13, 2014, which describes procedures for increasing the clearances between the fairing and the MLG inboard doors, and between the MLG fairing and adjacent structure of the MLG doors. This service bulletin also describes procedures for adjusting the MLG doors. 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 of this NPRM. 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. Costs of Compliance We estimate that this proposed AD affects 416 airplanes of U.S. registry. The actions that are required by AD 2010-23-19, Amendment 39-16508 (75 FR 68695, November 9, 2010), and retained in this proposed AD take about 1 work-hour per product, at an average labor rate of $85 per work-hour. Based on these figures, the estimated cost of the actions that are required by AD 2010-23-19 is $85 per inspection cycle for each product. We also estimate that it would take about 50 work-hours for each product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to [[Page 3040]] be $1,768,000, or $4,250 for each product. In addition, we estimate that any necessary follow-on replacement actions would take about 24 work-hours and require parts costing $2,626, for a cost of $4,666 per product. We have no way of determining the number of aircraft that might need these actions. 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 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) 2010-23-19, Amendment 39-16508 (75 FR 68695, November 9, 2010), and adding the following new AD: Bombardier, Inc.: Docket No. FAA-2015-8471; Directorate Identifier 2013-NM-153-AD.
