Discussion

On June 13, 2014, we issued AD 2014–12–12, Amendment 39–17873 (79 FR 36638, June 30, 2014) for Airbus Helicopters Model EC120B helicopters with serial numbers up to and including 1367 and with a sliding door part number (P/N) C526A2370101 installed and Model EC130B4 helicopters with sliding door P/N C526S1101051 installed. AD 2014–12–12 does not apply to helicopters with modification (MOD) 07 3796 or 07 2921 installed. AD 2014–12–12 requires inspecting the upper and lower locking pin control rod fittings and the star support pin for a crack and reinforcing the sliding door star support stringer by installing three carbon fabric plies.

AD 2014–12–12 was prompted by AD No. 2013–0093, dated April 15, 2013, and corrected on April 17, 2013, issued by EASA, which is the Technical Agent for the Member States of the European Union. EASA AD No. 2013–0093 was issued to correct an unsafe condition for Model EC120B and EC130B4 helicopters after a case was reported where passengers could not open a helicopter’s sliding door after landing. EASA advises that an investigation revealed a failure of the sliding door star axle support.

Actions Since AD 2014–12–12 Was Issued

Since we issued AD 2014–12–12, EASA has issued EASA AD No. 2015– 0020, dated February 11, 2015, to correct an unsafe condition for Model EC120B helicopters with sliding door P/ N C526A2370101 and Model EC130B4 helicopters sliding door P/N C526S1101051. EASA AD No. 2015– 0020 does not apply to helicopters with MOD A00565, 07 3796, or 07 2921. EASA AD No. 2015–0020 supersedes EASA AD No. 2013–0093. EASA advises that after it issued AD No. 2013– 0093, it discovered that the doors could be installed on all serial-numbered EC120B helicopters. Also, Eurocopter (now Airbus Helicopters) learned of difficulties with installing the angle bracket and plate used to reinforce the sliding door star support. Because of the distance between the star support pin and the bottom of the stringer on composite sliding doors, installation of the angle bracket and plate is not possible in a small number of sliding doors. Eurocopter subsequently revised its repair procedures to provide an alternate method for reinforcing the sliding door star support.

EASA advises that it consequently issued AD No. 2015–0020 to extend the applicability to all serial-numbered EC120B helicopters with the affected sliding doors. EASA AD No. 2015–0020 also requires compliance with the revised service information.

FAA’s Determination

These helicopters have been approved by the aviation authority of France and are approved for operation in the United States. Pursuant to our bilateral agreement with France, EASA, its technical representative, has notified us of the unsafe condition described in its AD. We are proposing this AD because we evaluated all known relevant information and determined that an unsafe condition is likely to exist or develop on other products of the same type design.

Related Service Information Under 1 CFR Part 51

We reviewed Eurocopter (now Airbus Helicopters) Alert Service Bulletin (ASB) No. EC120–52A014, Revision 2, dated October 28, 2013, for Model EC120B helicopters and ASB No. 130– 52A009, Revision 1, dated January 25, 2013, for Model EC130B4 helicopters. This service information specifies visual and dye penetrant inspections of sections of the sliding door attachment assembly and reinforcement of the sliding door star support. ASB EC120– 52A014 was changed at Revision 2 toexpand the applicability for all serialnumbered Model 120B helicopters and provides an alternative procedure for reinforcing the sliding door star support.

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. Proposed AD Requirements This proposed AD would require, within 165 hours time-in-service (TIS):

• Visually inspecting each upper and lower locking pin control rod end fitting (control end fitting) and replacing it before further flight if it is bent, twisted, or broken.

• Cleaning and dye-penetrant inspecting the star support pin for a crack and replacing it before further flight if it is cracked.

• Reinforcing the sliding door star support stringer by installing three carbon fabric plies.

This proposed AD would also prohibit installing a sliding door P/N C526A2370101 on a Model EC120B helicopter, or a sliding door P/N C526S1101051 on a Model EC130B4 helicopter, unless the sliding door star support stringer is reinforced as required by this proposed AD. Costs of Compliance

We estimate that this proposed AD would affect 261 helicopters of U.S. Registry and that labor costs average $85 a work hour. Based on these estimates, we expect the following costs:

• Visually inspecting the control rod end fittings would require 1 work-hour and a minimal amount for consumable materials for an estimated cost of $85 per helicopter, or $22,185 for the U.S. fleet.

• Replacing the control rod end fittings with airworthy fittings would require 5 work-hours for a labor cost of $425. Parts would cost about $242 for an estimated total cost of $667 per helicopter.

• Dye-penetrant inspecting the star support pin for a crack would require 2 work-hours and no parts for an estimated cost of $170 per helicopter and $44,370 for the U.S. fleet.

• Replacing the star support pin would require 5 work-hours. Parts would cost about $200 for an estimated total cost of $625 per helicopter.

• Installing three carbon fabric plies to reinforce the sliding door star support would require 5 work-hours. Parts would cost $200 for an estimated total cost of $625 per helicopter and $163,125 for the U.S. fleet. 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,


### 74364 Federal Register / Vol. 81, No. 207 / Wednesday, October 26, 2016 / Proposed Rules

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, 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 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 proposed 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. The Proposed Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
