[Federal Register Volume 82, Number 34 (Wednesday, February 22, 2017)] [Proposed Rules] [Pages 11325-11327] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2017-03262] ======================================================================= ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2016-9575; Directorate Identifier 2016-NM-168-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- 09 for certain Bombardier, Inc. Model DHC-8-400 series airplanes. AD 2014-20-09 currently requires an inspection for missing clamps that are required to provide positive separation between the alternating current (AC) feeder cables and the hydraulic line of the landing gear alternate extension, and related investigative and corrective actions if necessary. Since we issued AD 2014-20-09, it was determined that certain airplane serial numbers are not subject to the identified unsafe condition. This proposed AD would remove airplanes from the AD applicability. We are proposing this AD to address the unsafe condition on these products. DATES: We must receive comments on this proposed AD by April 10, 2017. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods:Federal eRulemaking Portal: Go to http://www.regulations.gov.

We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion On September 23, 2014, we issued AD 2014-20-09, Amendment 39-17982 (79 FR 59630, October 3, 2014) (``AD 2014-20-09''), for certain Bombardier, Inc. Model DHC-8-400 series airplanes. AD 2014-20-09 was prompted by reports of missing clamps that are required to provide positive separation between the AC feeder cables and the hydraulic line of the landing gear alternate extension. AD 2014-20-09 requires an inspection for missing clamps that are required to provide positive separation between the AC feeder cables and the hydraulic line of the landing gear alternate extension, and related investigative and corrective actions if necessary. We issued AD 2014-20-09 to detect and correct chafing of the AC feeder cable. A chafed and arcing AC feeder cable could puncture the adjacent hydraulic line, which, in combination with the use of the alternate extension system, could result in an in- flight fire. Since we issued AD 2014-20-09, it was determined that certain airplane serial numbers are in a Pre-modification MS 4M153025 configuration, which allows sufficient space between the AC feeder cables and the landing gear alternate extension hydraulic line do not pose an in-flight fire risk. Therefore, these airplanes are not subject to the identified unsafe condition. Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF- 2013-16R1, effective July 26, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for certain Bombardier, Inc. Model DHC-8- 400 series airplanes. The MCAI states: During production checks, it was found that the appropriate clamps required to provide positive separation between the AC feeder cables and the hydraulic line of the landing gear alternate extension were omitted. The AC feeder cable could sag and be in direct contact with the swage fitting of the landing gear alternate extension hydraulic line, resulting in chafing of the AC feeder cable. The chafed and arcing AC feeder cable could puncture the adjacent hydraulic line. In combination with the use of the alternate extension system, this could result in an in-flight fire. The original issue of this [Canadian] AD was issued to mandate the incorporation of [Bombardier] service bulletin (SB) 84-24-53 to * * * [do a general visual inspection for the presence of correctly installed clamps] and rectify, as necessary, for proper clamp installation. Bombardier, Inc. has revised SB 84-24-53 to remove serial numbers 4001 through 4034 from the Effectivity section, as it was determined that these serial numbers are Pre-Mod MS 4M153025, which allowed sufficient space between the AC feeder cables and the landing gear alternate extension hydraulic line to not pose an in- flight fire risk. Accordingly, revision 1 of this [Canadian] AD is issued to revise the [[Page 11326]] Applicability section to reflect the Effectivity changes in [Bombardier Service Bulletin] SB 84-24-53 Revision B, dated 10 September 2015. The related investigative action is a general visual inspection of the AC power feeder cables and the hydraulic line for damage due to chafing. The corrective actions include repair of chafed parts and replacement of missing clamps. 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-2016-9575. Related Service Information Under 1 CFR Part 51 We reviewed Bombardier Service Bulletin 84-24-53, Revision B, dated September 10, 2015. The service information describes procedures for a general visual inspection for installation of clamps between the AC feeder cables and hydraulic line, and related investigative and corrective 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. Costs of Compliance We estimate that this proposed AD affects 52 airplanes of U.S. registry. The actions required by AD 2014-20-09, 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 about $170 per product. Based on these figures, the estimated cost of the actions that are required by AD 2014-20-09 is $17,680 per product. This proposed AD merely removes certain airplanes and, therefore, adds no new actions or economic burden. 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) 2014-20-09, Amendment 39-17982 (79 FR 59630, October 3, 2014), and adding the following new AD: Bombardier, Inc.: Docket No. FAA-2016-9575; Directorate Identifier 2016-NM-168-AD. (a) Comments Due Date We must receive comments by April 10, 2017. (b) Affected ADs This AD replaces AD 2014-20-09, Amendment 39-17982 (79 FR 59630, October 3, 2014) (``AD 2014-20-09''). (c) Applicability This AD applies to Bombardier, Inc. Model DHC-400, -401, and - 402 airplanes, certificated in any category, serial numbers 4035 through 4347 inclusive. (d) Subject Air Transport Association (ATA) of America Code 24, Electrical power. (e) Reason This AD was prompted by reports of missing clamps that are required to provide positive separation between the alternating current (AC) feeder cables and the hydraulic line of the landing gear alternate extension. We are issuing this AD to detect and correct chafing of the AC feeder cable. A chafed and arcing AC feeder cable could puncture the adjacent hydraulic line, which, in combination with the use of the alternate extension system, could result in an in-flight fire. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Retained Clamp Inspection, Related Investigative Actions, and Corrective Actions, With Revised Service Information Having Reduced Effectivity This paragraph restates the requirements of paragraph (g) of AD 2014-20-09, with revised service information having reduced Effectivity. Within 6,000 flight hours or 36 months after November 7, 2014 (the effective date of AD 2014-20-09), whichever occurs earlier: Do a general visual inspection for correctly installed clamps between the AC feeder cables and hydraulic line, and do all applicable related investigative and corrective actions; in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 84-24-53, Revision B, dated September 10, 2015. Do all applicable related investigative and corrective actions before further flight. After the effective date of this AD, only Bombardier Service Bulletin 84-24-53, Revision B, dated September 10, 2015, may be used. (h) Credit for Previous Actions This paragraph provides credit for actions required by paragraph (g) of this AD, if those actions were performed before November 7, 2014 (the effective date of AD 2014-20-09), using Bombardier Service Bulletin 84-24-53, dated May 11, 2012; or Bombardier Service Bulletin 84-24-53, Revision A, dated May 16, 2013.
