[Federal Register Volume 81, Number 13 (Thursday, January 21, 2016)] [Rules and Regulations] [Pages 3310-3313] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2016-00664] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2014-0577; Directorate Identifier 2013-SW-042-AD; Amendment 39-18375; AD 2015-12-09 R1] RIN 2120-AA64 Airworthiness Directives; Airbus Helicopters Deutschland GmbH (Previously Eurocopter Deutschland GmbH) (Airbus Helicopters) AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are revising airworthiness directive (AD) 2015-12-09 for Airbus Helicopters Model EC135P1, EC135T1, EC135P2, EC135T2, EC135P2+, EC135T2+, and MBB-BK 117 C-2 helicopters. AD 2015-12-09 required inspecting certain washers for movement and making the appropriate repairs if the washers move. As published, AD 2015-12-09 referenced an incorrect date for the service information in the Credit for Previous Actions section. This AD corrects the error while retaining the requirements of AD 2015-12-09. These actions are intended to prevent loss of concerned control axis and subsequent loss of control of the helicopter. DATES: This AD is effective February 25, 2016. The Director of the Federal Register approved the incorporation by reference of certain documents listed in this AD as of July 23, 2015 (80 FR 34831, June 18, 2015).

SUPPLEMENTARY INFORMATION: Discussion On July 24, 2015, we issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to revise AD 2015-12-09, Amendment 39-18184 (80 FR 34831, June 18, 2015), which applied to Airbus Helicopters Model EC135P1, EC135T1, EC135P2, EC135T2, EC135P2+, EC135T2+, and MBB-BK 117 C-2 helicopters. The NPRM published in the Federal Register on August 3, 2015 (80 FR 45900). The NPRM was prompted by the discovery of an incorrectly dated Alert Service Bulletin (ASB) in the Credit for Previous Actions section of AD 2015-12-09. The NPRM proposed to retain the actions required by AD 2015-12-09 and correct the ASB date and revise other information throughout the AD. AD 2015-12-09 was prompted by AD No. 2013-0176, dated August 7, 2013, issued by EASA, which is the Technical Agent for the Member States of the European Union, to correct an unsafe condition for Eurocopter Deutschland GmbH Model EC 135 P1 (CDS), EC 135 P1 (CPDS), EC 135 P2+, EC 135 P2 (CPDS), EC 135 T1 (CDS), EC 135 T1 (CPDS), EC 135 T2+, EC 135 T2 (CPDS), EC 635 P2+, EC 635 T1 (CPDS), EC 635 T2+, and MBB-BK 117 C-2 helicopters. EASA advises that during installation work on a helicopter, it was discovered that it was not possible to install attachment hardware on a threaded blind borehole between the Smart Electro Mechanical Actuator (SEMA) and the control rod without play. EASA advises that this condition, if not detected and corrected, could lead to loss of the concerned control axis, possibly resulting in loss of helicopter control. For these reasons, EASA AD No. 2013-0176 requires a one-time inspection of the affected SEMA attachment hardware to detect improper connection and play and, depending on the findings, replacement of the affected hardware. After the issuance of EASA AD No. 2013-0176, Eurocopter Deutschland GmbH changed its name to Airbus Helicopters Deutschland GmbH. When AD 2015-12-09 was published, an incorrect reference to the date of Eurocopter ASB EC135-22A-015, Revision 0, dated May 13, 2008, appeared in the text of the rule. Specifically, AD 2015-12-09 includes the following under paragraph (f), Credit for Previous Actions: ``If you performed the actions in Eurocopter Alert Service Bulletin EC135- 22A-015, Revision 0, dated May 13, 2018, or Eurocopter Alert Service Bulletin MBB BK117 C-2-22A-009, Revision 0, May 13, 2008, before the effective date of this AD, you met the requirements of this AD.'' As published, the reference to May 13, 2018, is incorrect. The correct date for Eurocopter ASB EC135-22A-015, Revision 0, is May 13, 2008. Accordingly, we are revising AD 2015-12-09 to correct the date for Eurocopter ASB EC135-22A-015, Revision 0. Further, we updated the physical address of the FAA Southwest Regional Office throughout this AD and the email address for requesting an Alternative Method of Compliance (AMOC). We did not change any other part of the preamble or regulatory information. The final rule is reprinted in its entirety for the convenience of affected operators. Comments We gave the public the opportunity to participate in developing this AD, but we received no comments on the NPRM (80 FR 45900, August 3, 2015). FAA's Determination These helicopters have been approved by the aviation authority of Germany and are approved for operation in the United States. Pursuant to our bilateral agreement with Germany, EASA, its technical representative, has notified us of the unsafe condition described in the EASA AD. We are issuing this AD because we evaluated all information provided by EASA and determined the unsafe condition exists and is likely to exist or develop on other helicopters of these same type designs. Related Service Information Under 1 CFR Part 51 Eurocopter reported in ASBs EC135-22A-015, Revision 1, dated January 28, 2013, and MBB BK117 C-2-22A-009, Revision 1, dated August 3, 2009, that it was discovered during the installation work on a helicopter that it was not possible to establish attachment hardware on a threaded blind borehole between the SEMA and the control rod without play. The ASBs state that ``unfavourable adding of the tolerances'' of the individual attachment hardware elements caused the screw to push against the bottom of the threaded blind borehole on the SEMA, preventing any clamping force on the screw head. The ASBs call for inspecting the SEMA attachment hardware connected to their respective control rods for play and making the proper adjustments to eliminate any play. 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. Costs of Compliance We estimate that this AD affects 385 helicopters of U.S. Registry and that labor costs average $85 per work-hour. Based on these estimates, we expect the following costs:Inspecting for movement of the washers requires 1.5 work- hours for a labor cost of $128 per helicopter and $49,280 for the U.S. fleet. Replacing the screws and related work requires an additional 0.5 work-hours for a labor cost of $43. Screws cost $4 each while washers cost $10 each. We estimate the cost at $79 per repair. 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 have determined that this AD will not have federalism implications under Executive Order 13132. This AD will 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 [[Page 3312]] responsibilities among the various levels of government. For the reasons discussed above, I certify that this AD: (1) Is not a ``significant regulatory action'' under Executive Order 12866, (2) Is not a ``significant rule'' under 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.
