[Federal Register Volume 82, Number 134 (Friday, July 14, 2017)] [Proposed Rules] [Pages 32496-32498] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2017-14591] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2015-8434; Directorate Identifier 2015-NM-082-AD] RIN 2120-AA64 Airworthiness Directives; Bombardier, Inc., Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Supplemental notice of proposed rulemaking (SNPRM); reopening of comment period. ----------------------------------------------------------------------- SUMMARY: We are revising an earlier proposal for certain Bombardier, Inc., Model DHC-8-401 and -402 airplanes. This action revises the notice of proposed rulemaking (NPRM) by adding certain airplanes to the applicability and adding specified actions. We are proposing this airworthiness directive (AD) to address the unsafe condition on these products. Since these changes increase the scope of the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes. DATES: The comment period for the NPRM published in the Federal Register on January 13, 2016 (81 FR 1586), is reopened. We must receive comments on this SNPRM by August 28, 2017.

SUPPLEMENTARY INFORMATION: Comments Invited We invite you to send any written relevant data, views, or arguments about this proposal. Send your comments to an address listed under the ADDRESSES section. Include ``Docket No. FAA-2015-8434; Directorate Identifier 2015-NM-082-AD'' at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this proposed AD. We will consider all comments received by the closing date and may amend this proposed AD based on 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 proposed AD. Discussion We issued an NPRM to amend 14 CFR part 39 by adding an AD that would apply to certain Bombardier, Inc. Model DHC-8-401 and -402 airplanes. The [[Page 32497]] NPRM published in the Federal Register on January 13, 2016 (81 FR 1586) (``the NPRM''). The NPRM was prompted by a discovery of cracking on two test spoiler power control units (PCUs) manifolds during testing by the manufacturer. The NPRM proposed to require replacement of affected spoiler PCUs. Actions Since the NPRM Was Issued Since we issued the NPRM, we have determined that certain airplanes were inadvertently omitted from the applicability of the NPRM; and additional actions were necessary. Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF- 2015-07R2, dated December 14, 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- 401 and -402 airplanes. The MCAI states: During endurance and impulse testing of the spoiler PCU, cracks were discovered on two test spoiler PCU manifolds. Investigation determined that the crack initiation was due to the heat treat process. A cracked spoiler PCU manifold could cause the loss of one of the two hydraulic systems, resulting in the loss of multiple flight controls and landing gear systems. This condition, if not corrected, could adversely affect the continued safe operation and landing of the aeroplane. This [Canadian] AD mandates the replacement of the affected spoiler PCUs. Revision 1 of this [Canadian] AD was issued to extend the applicability to include additional aeroplane serial numbers and also modify the Corrective Actions to specifically mandate section 3.B of the [Service Bulletin] SB 84-27-64, Revision A. Revision 2 of this [Canadian] AD was issued to correct the SB referenced in the Background section. SB 84-27-64, Revision A should have been referenced in lieu of SB 84-27-63, Revision A. 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- 8434. Related Service Information Under 1 CFR Part 51 Bombardier, Inc. has issued Bombardier Service Bulletin 84-27-64, Revision A, dated July 26, 2016. The service information describes procedures for replacement of affected spoiler PCU manifolds. Parker-Hannifin Corporation has issued Parker Service Bulletin 390700-27-002, Revision 1, dated April 13, 2016. This service bulletin identifies affected spoiler PCUs that need to be returned to Parker Customer Support for rework. 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. Comments We gave the public the opportunity to participate in developing this proposed AD. We considered the comment received. Request To Remove Requirement for Job Set-up and Close-out Horizon Air requested that paragraph (g) of the proposed AD (in the NPRM) be revised to remove the requirement for job set-up and close-out in the Accomplishment Instructions of Bombardier Service Bulletin 84- 27-64, dated July 15, 2014. Horizon Air stated that performing the job set-up and close-out sections specified in Bombardier Service Bulletin 84-27-64, dated July 15, 2014, as a requirement of the AD, restricts an operator's ability to perform other maintenance in conjunction with incorporating Bombardier Service Bulletin 84-27-64, dated July 15, 2014. We agree that job set-up and close-out may be done using approved procedures other than those provided in the Accomplishment Instructions of Bombardier Service Bulletin 84-27-64, dated July 15, 2014, or Revision A, dated July 26, 2016. Therefore, access and close would not be specifically required by this proposed AD. We have revised paragraph (g) of this proposed AD (in the SNPRM) to require only the actions specified in paragraph 3.B. in the Accomplishment Instructions of Bombardier Service Bulletin 84-27-64, Revision A, dated July 26, 2016. We find that this change adequately addresses the commenter's request. FAA's Determination and Requirements of This SNPRM 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. Certain changes described above expand the scope of the NPRM. As a result, we have determined that it is necessary to reopen the comment period to provide additional opportunity for the public to comment on this SNPRM. Costs of Compliance We estimate that this SNPRM affects 82 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: Estimated costs ---------------------------------------------------------------------------------------------------------------- Cost on Action Labor cost Parts cost Cost per product U.S. operators ---------------------------------------------------------------------------------------------------------------- Remove and replace affected PCUs 2 work-hours x $85 per $10,000 per $10,170 per $833,940 hour = $170 per airplane. airplane. airplane. ---------------------------------------------------------------------------------------------------------------- The new requirements of this proposed AD add no additional 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 [[Page 32498]] 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.
