Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA AD 2016-0167, dated August 17, 2016 (referred to after this as “the MCAI”), to address the unsafe condition on these products. The MCAI states:

Cases of corrosion and cracks were found on Zodiac Seats France CAS 536 rear cabin attendant seats installed on some ATR 42 and ATR 72 aeroplanes. The detected damage was located on the lower parts of the attendant seat, at the level of the seat-to-floor interface. This condition, if not detected and corrected, could lead to failure of the seat Start Printed Page 46680occupied by the cabin attendant, possibly resulting in injury to the seat occupant. To address this potential unsafe condition, Zodiac Seats France issued Service Bulletin (SB) No. 536-25-002 to provide inspection instructions.

For the reason described above, this [EASA] AD requires repetitive inspections of the affected attendant seats, and, depending on findings, accomplishment of the temporary corrective action(s). This [EASA] AD is considered as interim action and further [EASA] AD action may follow. Zodiac Seats France is developing a solution preventing this kind of damage.

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-2017-0839.

Related Service Information Under 1 CFR Part 51

We reviewed Zodiac Seats France Service Bulletin (SB) No. 536-25-002, Revision 3, dated September 30, 2016. The SB describes procedures for inspection, repair, or replacement of the seat structure and clamps known to be installed on the main structure. 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.

FAA's Determination

This product has been approved by EASA, and is approved for operation in the United States. Pursuant to our bilateral agreement with the European Community, EASA has notified us of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all the relevant information provided by EASA and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design.

Proposed AD Requirements

This proposed AD would require inspection and modification of all Zodiac Seats France 536-Series Cabin Attendant Seats.

Costs of Compliance

We estimate that this proposed AD affects 55 seat structures installed on, but not limited to, ATR 42 and ATR 72 airplanes of U.S. registry.

We estimate the following costs to comply with this proposed AD:

Estimated costs

ActionLabor costParts costCost per productCost on U.S. operators
Seat inspection, visual (on-wing)0.2 work-hours × $85 per hour = $17$0$17$935
Seat inspection, (shop visit)0.5 work-hours × $85 per hour = $42.50042.502,337.50
Part replacement/repair2.0 work-hours × $85 per hour = $1702,0002,170119,350

According to the manufacturer, some of the costs of this proposed 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

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 above, 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, 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.
