[Federal Register Volume 80, Number 185 (Thursday, September 24, 2015)] [Proposed Rules] [Pages 57543-57545] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2015-24020] ======================================================================== Proposed Rules Federal Register ________________________________________________________________________ This section of the FEDERAL REGISTER contains notices to the public of the proposed issuance of rules and regulations. The purpose of these notices is to give interested persons an opportunity to participate in the rule making prior to the adoption of the final rules. ======================================================================== Federal Register / Vol. 80, No. 185 / Thursday, September 24, 2015 / Proposed Rules [[Page 57543]] DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2015-3634; Directorate Identifier 2014-NM-203-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) 2014-20- 01, for certain Bombardier, Inc. Model CL-600-2B16 (CL-601-3A, CL-601- 3R, and CL-604 Variants) airplanes. AD 2014-20-01 currently requires repetitive inspections for any fuel leak in the right-hand landing lights compartment, and related investigative and corrective actions if necessary. AD 2014-20-01 also provides for an optional replacement of the connector of the fuel boost pump canister of the auxiliary power unit (APU), which terminates the repetitive inspections. Since we issued AD 2014-20-01, we have determined that a terminating action for the repetitive inspections is necessary. This proposed AD would retain the repetitive inspections for any fuel leak in the right-hand landing lights compartment and the related investigative and corrective actions, and would require replacing the connector of the fuel boost pump canister of the APU. We are proposing this AD to detect and correct fuel leaks in the right-hand landing lights compartment, which, in combination with the heat generated by the taxi lights and landing lights on the ground reaching the auto-ignition temperature of the fuel, could result in ignition of any fuel or fumes present in the right-hand landing lights compartment. DATES: We must receive comments on this proposed AD by November 9, 2015. ADDRESSES: You may send comments by any of the following methods:Federal eRulemaking Portal: Go to http://www.regulations.gov.

Discussion On September 19, 2014, we issued AD 2014-20-01, Amendment 39-17974 (79 FR 59640, October 3, 2014). AD 2014-20-01 requires actions intended to address an unsafe condition on certain Bombardier, Inc. Model CL- 600-2B16 (CL-601-3A, CL-601-3R, and CL-604 Variants) airplanes. The preamble of AD 2014-20-01 specified that we considered the actions an interim action and that we were considering requiring ``a replacement of the connector of the fuel boost pump canister of the APU, and applicable corrective actions, which would constitute terminating action for the repetitive inspections required by this AD action.'' Since we issued AD 2014-20-01, Amendment 39-17974 (79 FR 59640, October 3, 2014), we have determined that further rulemaking is indeed necessary; this proposed AD follows from that determination. Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF- 2014-21, dated July 10, 2014 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for certain Bombardier, Inc. Model CL-600-2B16 (CL- 601-3A, CL-601-3R, and CL-604 Variants) airplanes. The MCAI states: Bombardier, Inc. has discovered fuel leakage in the auxiliary power unit (APU) fuel Boost Pump (BP) canister connector cavity. On some of those aeroplanes, leakage was also noticed at the APU fuel BP electrical conduit connection in the right hand landing light compartment. The root cause of the subject fuel leak is identified to be the [[Page 57544]] improper length of the female connector keyway located in the fuel BP canister, causing a shift of the electrical harness and its seals. Available data indicates that on a hot day, due to the heat generated by the taxi light and/or landing lights on the ground, temperature in the landing light compartment can reach the fuel auto ignition temperature. Therefore, presence of any fuel in the right hand landing light compartment is considered to be a safety hazard [fuel or fumes present in the right-side landing lights compartment might ignite] that warrants mitigating action. In order to help mitigate the potential safety hazard precipitated by any fuel leakage in the right hand landing light compartment, Bombardier, Inc., has revised the Aircraft Flight Manual (AFM) through Temporary Revisions (TRs) 604/38 and 605/20 dated 16 June 2014 to restrict the operation of Taxi and Landing lights on the ground. Transport Canada issued Emergency [Canadian] AD CF-2014-17 [(http://ad.easa.europa.eu/ad/CF-2014-17) which corresponds to FAA AD 2014-15-17, Amendment 39-17919 (79 FR 44268, July 31, 2014] to mandate incorporation of the above AFM TRs. To address the root cause of the subject fuel leakage from the APU fuel boost pump canister wiring conduit, Bombardier, Inc. issued Alert Service Bulletin (ASB) A605-28-008 that requires periodic [repetitive general visual] inspection[s] for fuel leaks and [applicable related investigative and corrective actions and] eventual the replacement of the discrepant fuel BP canister connectors [including related investigative and corrective actions] on affected aeroplanes. The ASB has been revised to include an additional inspection of the new connector wiring for damage and this [Canadian] AD is issued to mandate the compliance with ASB A605-28-008 Revision 2 requirements. We also included compliance times for the terminating action. 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- 3634. 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 92 airplanes of U.S. registry. The actions required by AD 2014-20-01, Amendment 39-17974 (79 FR 59640, October 3, 2014), and retained in this proposed AD take about 2 work-hours per product, at an average labor rate of $85 per work-hour. Required parts cost $0 per product. Based on these figures, the estimated cost of the actions that are required by AD 2014-20-01 is $170 per product. We also estimate that it would take about 22 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost $0 per product. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $172,040, or $1,870 per product. According to the manufacturer, some of the costs of this proposed 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. 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) 2014-20-01, Amendment 39-17974 (79 FR 59640, October 3, 2014), and adding the following new AD: Bombardier, Inc.: Docket No. FAA-2015-3634; Directorate Identifier 2014-NM-203-AD.
