SUPPLEMENTARY INFORMATION: Comments Invited This AD is a final rule that involves requirements affecting flight safety, and we did not provide you with notice and an opportunity to provide your comments prior to it becoming effective. However, we invite you to participate in this rulemaking by submitting written comments, data, or views. We also invite comments relating to the economic, environmental, energy, or federalism impacts that resulted from adopting this AD. The most helpful comments reference a specific portion of the AD, explain the reason for any [[Page 12294]] recommended change, and include supporting data. To ensure the docket does not contain duplicate comments, commenters should send only one copy of written comments, or if comments are filed electronically, commenters should submit them only one time. We will file in the docket all comments that we receive, as well as a report summarizing each substantive public contact with FAA personnel concerning this rulemaking during the comment period. We will consider all the comments we receive and may conduct additional rulemaking based on those comments. Discussion EASA, which is the Technical Agent for the Member States of the European Union, has issued Emergency AD No. 2016-0118-E, dated June 17, 2016, to correct an unsafe condition for Airbus Helicopters Model BO105 C, BO105 D, BO105 LS A-3, and BO105 S helicopters, all variants except CB-5, D, DS, DBS-5, and CBS-5. According to EASA, during an inspection on a Model BO105 S helicopter, debonding was found on the erosion protective shell (shell) of an MRB, caused by incorrect preparation of the shell prior to the bonding process. EASA further states that this condition, if not detected and corrected, could result in loss of the shell in-flight, which could strike the tailboom or the tail rotor, causing an imbalance in the main rotor and high vibrations. EASA also advises that these high vibrations could damage the helicopter, resulting in loss of tail rotor control and subsequent loss of control of the helicopter. To address this unsafe condition, EASA AD 2016-0118-E requires repetitive inspections of the shells for debonding within 10 hours time-in-service (TIS) and thereafter at 50-hour TIS intervals. After the shells have completed 200 hours TIS since the shell was installed and completed an inspection of the shell, the EASA AD no longer requires the repetitive 50 hour TIS inspections. The EASA AD applies to certain part-numbered MRBs on which the shell was last replaced between December 1, 2010, and February 28, 2015, inclusive, or for which there is no maintenance record available to determine the date the shell was last replaced. 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 We reviewed Airbus Helicopters Emergency Alert Service Bulletin (EASB) BO105-10A-128, Revision 0, dated June 16, 2016, for Model BO105C, D, and S helicopters and EASB No. BO105 LS-10A-016, Revision 0, dated June 16, 2016, for Model BO105 LS A-3 helicopters. This service information specifies repetitively inspecting the MRB shell for delamination in accordance with the helicopter's maintenance manual procedures. Differences Between This AD and the EASA AD The EASA AD is applicable to the Model BO105D helicopter; this AD is not because it does not have a type certificate in the U.S. The EASA AD prohibits installing an affected MRB on any helicopter until its AD actions have been complied with. This AD does not. AD Requirements This AD applies to helicopters with certain part-numbered MRBs with shells that were last replaced between December 1, 2010, and February 28, 2015, inclusive or where the most recent date of replacement of the shell cannot be determined from the helicopter maintenance records. This AD requires inspecting each MRB shell for debonding within 10 hours TIS and thereafter at intervals not to exceed 50 hours TIS until the MRB reaches 200 hours TIS. After the blade has accumulated 200 hours TIS since the last shell replacement, the 50 hours TIS inspections are terminated. If there is any debonding, this AD requires repairing or replacing the MRB before further flight. Costs of Compliance We estimate that this AD affects 73 helicopters of U.S. Registry. At an average labor rate of $85, we estimate that operators may incur the following costs in order to comply with this AD. Inspecting the MRB shells will require 1 work-hour, for a total cost of $85 per helicopter and $6,205 for the fleet, per inspection cycle. If required, replacing an MRB will require 2 work-hours and required parts will cost $114,000, for a cost per helicopter of $114,170. FAA's Justification and Determination of the Effective Date Providing an opportunity for public comments prior to adopting these AD requirements would delay implementing the safety actions needed to correct this known unsafe condition. Therefore, we find that the risk to the flying public justifies waiving notice and comment prior to the adoption of this rule because the inspections required by this AD must be accomplished within 10 hours TIS and 50 hours TIS, a very short interval for helicopters used in helicopter air ambulance operations. Since an unsafe condition exists that requires the immediate adoption of this AD, we determined that notice and opportunity for public comment before issuing this AD are impracticable and that good cause exists for making this amendment effective in less than 30 days. 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 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 responsibilities among the various levels of government. For the reasons discussed, 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); [[Page 12295]] 3. Will not affect intrastate aviation in Alaska to the extent that it justifies making a regulatory distinction; 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. We prepared an economic evaluation of the estimated costs to comply with this AD and placed it in the AD docket. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39--AIRWORTHINESS DIRECTIVES 0 1.
