AD 2018-16-13

We are adopting a new airworthiness directive (AD) for certain Zodiac Seats France, 537-Series Cabin Attendant Seats. This AD was prompted by operator reports that safety belt wear was found at the attachment to the cabin attendant seat. This AD requires inspecting the safety belt webbing, and modifying and re-marking each affected cabin attendant seat. We are issuing this AD to address the unsafe condition on these products.

Final rule.

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Zodiac Seats France, 537-Series Cabin Attendant Seats. The NPRM published in the Federal Register on December 11, 2017 (82 FR 58137). The NPRM was prompted by operator reports that safety belt wear was found at the attachment to the cabin attendant seat. The NPRM proposed to require inspecting the safety belt webbing, and modifying and re-marking each affected cabin attendant seat. We are issuing this AD to address the unsafe condition on these products.
The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA AD 2016-0163, dated August 10, 2016 (referred to after this as ``the MCAI''), to address the unsafe condition on these products. The MCAI states:

Cases were reported by operators of finding safety belt worn out at the attachment to the cabin attendant seat. This kind of belt damage is due to chafing between the belt and the surrounding metal lap belt fitting of the cabin attendant seat. This condition, if not detected and corrected, could lead to failure of the attendant seat to perform its intended function, possibly resulting in injury to the seat occupant. Prompted by these occurrences, Zodiac Seats France issued Service Bulletin (SB) No. 537-25-003, providing instructions to modify the affected seats. For the reason described above, this [EASA] AD requires a modification of the seat pan shaft by installing new seat pan spacers, and subsequent re-identification with a new P/N.

You may obtain further information by examining the MCAI in the AD docket on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2017-0688.

Comments

We gave the public the opportunity to participate in developing this final rule. We received no comments on the NPRM or on the determination of the cost to the public.

Conclusion

We reviewed the relevant data and determined that air safety and the public interest require adopting this final rule as proposed except for minor editorial changes. We have determined that these minor changes:
Are consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and
Do not add any additional burden upon the public than was already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

We reviewed Zodiac Seats France Service Bulletin (SB) No. 537-25- 003, Revision 1, dated August 29, 2016. The SB describes procedures for installing an anti-rotation device on the seat pan shaft to limit the rotation of the safety belt. We also reviewed Zodiac Seats France Service Information Letter (SIL) 537-01, dated July 31, 2015. The SIL provides details to identify if the safety belt must be removed and replaced and provides instructions on safetybelt storage to avoid this premature wear. 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 55 seat assemblies installed on, but not limited to, Avions de transport regional (ATR) 42 and ATR 72 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:

Estimated Costs ----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- Seat inspection and modification...... 0.5 work-hours x $85 per $300 $342.50 $18,837.50
hour = $42.50. ----------------------------------------------------------------------------------------------------------------

According to the manufacturer, 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 for affected individuals. As a result, we have included all costs in our cost estimate.

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.
This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to engines, propellers, and associated appliances to the Manager, Engine and Propeller Standards Branch, Policy and Innovation Division.

Regulatory Findings

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 above, I certify this AD:
(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.
