2017-14546. Airworthiness Directives; GEVEN S.p.A., Seat Assemblies, Type D1-02 and D1-03

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

We propose to adopt a new airworthiness directive (AD) for certain Geven S.p.A., Type D1-02 and D1-03 seat assemblies. This proposed AD was prompted by a report that seat belt attachment bolts were found detached or partially detached from the seat. This proposed AD would require inspection, torque verification, and modification of certain model seats. We are proposing this AD to correct the unsafe condition on these products.

DATES:

We must receive comments on this NPRM by August 28, 2017.

Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA AD 2014-0187, dated August 20, 2014 (referred to hereinafter as “the MCAI”), to correct an unsafe condition for the specified products. The MCAI states:

An operator reported that seat belt attachment bolts were found detached or partially detached from the seat. A further check on several aeroplanes revealed that on a large number of seats of the same model, the seat belt attachment bolts were not properly torqued and secured as defined. This condition, if not detected and corrected, could lead to failure of the seats to perform their intended function, possibly resulting in injury to occupants in case of an emergency landing. To address this potential unsafe condition, Geven published SB No. D103-25-004 to provide inspection instructions to verify if the seat belt attachment bolts are properly torqued and secured, and correction of any deficiencies. In addition, for certain D1-03 seats, the SB provides instructions to modify the seat belt attachment assembly. For the reasons described above, this AD requires a one-time inspection of all safety belt attachment bolts and, depending on findings, accomplishment of the applicable corrective action(s). This AD also requires modification of the seat belt attachment assembly on certain D1-03 seats.

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-2017-0504.

Related Service Information Under 1 CFR Part 51

Geven S.p.A. has issued Service Bulletin (SB) No. D103-25-004, Revision 4, dated March 15, 2016. The SB describes procedures for inspection, torque verification, and modification of certain model seats known to be installed on ATR 42 and ATR 72 airplanes. 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 and Requirements of This Proposed AD

This product has been approved by the aviation authority of Italy, 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 information provided by EASA and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. This proposed AD would require inspection, torque verification and modification of certain model seats.

Costs of Compliance

We estimate that this proposed AD affects an unknown number of seat assemblies installed on, but not limited to, 38 ATR 42 and ATR 72 airplanes of U.S. registry.

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

Estimated Costs

Action	Labor cost	Parts cost	Cost per product	Cost on U.S. operators
Seat modification ATR 42	1.5 work-hours × $85 per hour = $127.50	$302	$429.50	$10,737.50
Torque check ATR 42	0.8 work-hours × $85 per hour = $68.00	0	68.00	1,700.00
Seat modification ATR 72	2.3 work-hours × $85 per hour = $195.50	368	563.50	7,325.50
Seat remove and replace ATR 72	1.2 work-hours × $85 per hour = $102.00	0	102.00	1,326.00

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.

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 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.
