AD 2017-16-04

We are adopting a new airworthiness directive (AD) for Romtex torso restraint systems (restraint systems) installed on but not limited to Airbus Helicopters Model AS350B2, AS350B3, EC130B4, EC130T2, and AS355NP helicopters. This AD requires replacing certain restraint system buckles. This AD was prompted by a report of several restraint system buckle knobs breaking. The actions of this AD are intended to correct an unsafe condition on these products.

Final rule.

Adoption of the Amendment \n\n\n\tAccordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: \n\nPART 39--AIRWORTHINESS DIRECTIVES \n\n0 1. The authority citation for part 39 continues to read as follows: \n\n\n\tAuthority: 49 U.S.C. 106(g), 40113, 44701. \n\n\n\nSec. 39.13 (Amended) \n\n0 2. The FAA amends Sec. 39.13 by adding the following new airworthiness directive (AD): \n\n2017-16-04 Romtex Anjou Aeronautique (Romtex) Torso Restraint Systems: Amendment 39-18981; Docket No. FAA-2017-0068; Product Identifier 2014-SW-076-AD. \n\n(a) Applicability \n\n\n\tThis AD applies to Romtex torso restraint systems (restraint systems) with a rotary buckle sub-assembly (buckle assembly) with a part number and serial number as listed in the Effectivity, paragraph 1.2, of Anjou Aero Service Bulletin No. 358SB-14-101, Revision 1, dated December 12, 2014.

Discussion \n\n\n\tOn February 17, 2017, at 82 FR 10971, the Federal Register published our notice of proposed rulemaking (NPRM), which proposed to amend 14 CFR part 39 by adding an AD that would apply to Romtex restraint systems with a rotary buckle sub-assembly (buckle assembly) with a part number and serial number listed in Romtex Service Bulletin No. 358SB-14-101, Revision 1, dated December 12, 2014. These restraint systems are installed on, but not limited to, Airbus Helicopters Model AS350B2, AS350B3, EC130B4, EC130T2, and AS355NP helicopters. The NPRM proposed to require inspecting the buckle assembly to determine whether the straps release, marking the seat as inoperative if the buckle fails to release the straps, and replacing the buckle assembly within 180 hours time-in-service (TIS). The NPRM also proposed to prohibit installing the affected buckle assemblies on any helicopter. The proposed requirements were intended to prevent a restraint system strap from failing to release from the buckle, preventing occupants from exiting the helicopter during an emergency. \n\tThe NPRM was prompted by AD No. 2014-0279, dated December 19, 2014, issued by EASA, which is the Technical Agent for the Member States of the European Union, to correct an unsafe condition for Romtex Model 358 torso restraint systems installed on Airbus Helicopters Model EC130T2, AS350B2, and AS350B3 helicopters. EASA advises that ruptures have occurred on the upper side (knob) of several rotary buckles installed on these restraint systems. EASA states the material used in two batches of the buckle assembly were altered by a supplier, resulting in a specification different from the approved design data. The EASA AD states that this condition could prevent the release of the restraint system straps as intended after an emergency landing. To address this unsafe condition, the EASA AD requires inspecting the buckle \n\n((Page 39356)) \n\nassembly for proper operation,replacing or marking as inoperative any buckle assembly that fails to release the straps before further flight, and replacing all buckle assemblies within 6 months. The EASA AD also prohibits installing these buckle assemblies on any aircraft. \n\nComments \n\n\n\tWe gave the public the opportunity to participate in developing this AD, but we did not receive any comments on the NPRM. \n\nFAA's Determination \n\n\n\tThese products have been approved by the aviation authority of Romania and are approved for operation in the United States. Pursuant to our bilateral agreement with Romania, 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 and that air safety and the public interest require adopting the AD requirements as proposed except we are correcting the name in the related service bulletin from Romtex to Anjou Aero. This change is consistent with the intent of the proposals in the NPRM and will not increase the economic burden on any operator nor increase the scope of this AD. \n\nDifferences Between This AD and the EASA AD \n\n\n\tThe EASA AD requires compliance within 30 days for the buckle inspection and 6 months for replacement; this AD requires the inspection within 30 hours TIS and replacement within 180 hours TIS. The EASA AD does not apply to Model EC130B4 and AS355NP helicopters, and this AD does. \n\nRelated Service Information Under 1 CFR Part 51 \n\n\n\tWe reviewed Anjou Aero Service Bulletin No. 358SB-14-101, Revision 1, dated December 12, 2014 (SB 358SB-14-101), which specifies removing from service certain part-numbered and serial-numbered buckle assemblies, consisting of the rotary buckle, belt, and attachment. \n\tThis service information is reasonably available because the interested parties have accessto it through their normal course of business or by the means identified in the ADDRESSES section. \n\nCosts of Compliance \n\n\n\tWe estimate that this AD affects 893 helicopters of U.S. Registry. \n\tWe estimate that operators will incur the following costs in order to comply with this AD. At an average labor rate of $85 per hour, inspecting the buckle assembly requires about .5 work-hour, for a cost per helicopter of $43 and a total cost of $38,399 for the fleet. Replacing each buckle assembly requires about .5 work-hour, and required parts will cost $42,000, for a cost per helicopter of $42,043 and a total cost to U.S. operators of $37,544,399. \n\tAccording to the Anjou Aero service information, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage by Anjou Aero. Accordingly, we have included all costs in our cost estimate. \n\nAuthority for This Rulemaking \n\n\n\tTitle 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. \n\tWe 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 helicopters identified in this rulemaking action. \n\nRegulatory Findings \n\n\n\tThis AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationshipbetween the national government and the States, or on the distribution of power and responsibilities among the various levels of government. \n\tFor the reasons discussed above, I certify that this AD: \n\t(1) Is not a ''significant regulatory action'' under Executive Order 12866; \n\t(2) Is not a ''significant rule'' under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); \n\t(3) Will not affect intrastate aviation in Alaska to the extent that it justifies making a regulatory distinction; and \n\t(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. \n\tWe prepared an economic evaluation of the estimated costs to comply with this AD and placed it in the AD docket. \n\nList of Subjects in 14 CFR Part 39 \n\n\n\tAir transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.
