Federal Aviation Administration (FAA), Department of Transportation (DOT).
We are adopting a new airworthiness directive (AD) for Embraer S.A. Models EMB-500 and EMB-505 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as incorrect installation of passenger seat attachment fittings. We are issuing this AD to correct the unsafe condition on these products.
This AD is effective December 1, 2016.
The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of December 1, 2016.

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to Embraer S.A. Models EMB-500 and EMB-505 airplanes. The NPRM was published in the Federal Register on July 7, 2016 (81 FR 44238). The NPRM proposed to correct an unsafe condition for the specified products and was based on mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country. The MCAI states:
There is the possibility that certain attachment fittings of passenger seats have been incorrectly installed. This AD results from a determination that the passenger seat on which the attachment fittings were improperly installed may not meet certain static strength, and dynamic strength criteria. Failure to meet static and dynamic strength criteria could result in injuries to the occupants during an emergency landing condition.
This AD requires the inspection of each passenger seat for the correct installation of the attachment fittings and correction, if necessary.
The MCAI can be found in the AD docket on the Internet at: https://www.regulations.gov/document?D=FAA-2016-8160-0001.
We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM and the FAA's response to each comment.
Request To Withdraw the Proposed AD and Replace With SAIB
Embraer S.A requested that the FAA withdraw this AD stating there is no data available considering the real seat dynamic strength if the fittings were not assembled in the correct way, as this wrong configuration was never tested during the seat certification process. The commenter stated that assuming the possible uncorrected seat fittings were installed, the unsafe condition would require a survivable crash landing to exist. Due to lack of better data and considering a total of six (6) hull losses in the fleet as being survivable crash landings, then the current fleet probability of a crash landing would be 1,15 X 10-5. Based on this consideration, Embraer understood that the probability of an unsafe condition would be extremely remote, therefore not justifying the issuance of an AD as per 14 CFR part 39 requirements.
The commenter suggested that the issuance of a special airworthiness information bulletin (SAIB) would be more appropriate for a possible improper installation because, per FAA definition, the “Special Airworthiness Information Bulletin (SAIB) is an information tool that alerts, educates, and makes recommendations to the aviation community. SAIBs contain non-regulatory information and guidance that does not meet the criteria for an AD.”
We don't agree because as part of the investigation into the Embraer request, the FAA contacted the Brazilian Airworthiness Authority, ANAC, to get their input as the certifying authority and originator of the original mandatory continuing airworthiness information (MCAI). ANAC reported that they had received similar comments from Embraer and had decided to go ahead and issue their AD. They justified this decision because there is no data indicating that a seat installation on which the aluminum and steel fittings have been switched would meet the static and dynamic criteria. They also reasoned that the seat assembly criteria for the current requirements are to provide a specific level of safety to the occupants in case of impact. Therefore, they disagreed with removing these safety features just because they would only be used in a crash landing event. After review of the Embraer request and the related comments from ANAC, the FAA has decided that we agree with ANAC and will not withdraw our proposed AD for this unsafe condition.
Request To Change Wording for Passenger Seat
Justin Collins requested that the FAA make changes to the wording of the proposed AD Applicability, paragraph (c)(2), which excludes “any passenger seat replaced during routine maintenance.” The commenter believes that a more appropriate phrase would be “any passenger seat removed and reinstalled” or “any passenger seat that has been installed.”
The commenter states that the word ‘replaced’ in the proposed AD infers a different part has been installed.
We don't agree with adding the concept of `reinstallation' to the final rule. If the unsafe condition exists on the aircraft, it is possible that this seat could be removed and reinstalled without the fitting installation being corrected and thus still have the unsafe Start Printed Page 74670condition. The Embraer S.A. Service Bulletin (SB) No. 500-25-0016, dated December 8, 2015, states in paragraph 1.A., that “This effectivity list includes the aircraft originally equipped with the affected component. Since this component is a “Line Replaceable Unit” (LRU), it may be necessary to refer to the fleet maintenance control record and verify whether the unit has been replaced with another one during routine maintenance.” The other referenced Embraer SB for the Model EMB-505 has a similar note. The point is that the unsafe condition originated during the manufacturing process of the seat assembly. If an affected seat is replaced with a different seat during subsequent maintenance, then the unsafe condition is no longer a factor as the new seat should be assembled according to correct instructions. For this reason, the FAA will not add the word `reinstall' to the final rule based on this comment. However, in order to better reflect the wording in the service information, we will add the words “with another one” after the word “replaced” and before the phrase “during routine maintenance.”
We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting the AD with the change described previously and minor editorial changes. We have determined that these minor changes:
- Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and
- Do not add any additional burden upon the public than was already proposed in the NPRM.
We also determined that these changes will not increase the economic burden on any operator or increase the scope of the AD.
Related Service Information Under 1 CFR Part 51
We reviewed Embraer S.A. Service Bulletin (SB) No.: 500-25-0016, dated December 8, 2015; and Embraer S.A. SB No.: 505-25-0020, dated December 8, 2015. The service information describes procedures for inspection of the passenger seat attachment fittings and correction to the fittings if necessary on the applicable airplane models. 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 of the AD.
Costs of Compliance
We estimate that this AD will affect 203 products of U.S. registry. We also estimate that it would take about 4 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour.
Based on these figures, we estimate the cost of this AD on U.S. operators to be $69,020, or $340 per product.
In addition, we estimate that any necessary follow-on actions would take about 6 work-hours for a cost of $510 per product. We have no way of determining the number of products that may need these actions.
According to the manufacturer, all 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.
We determined that 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.

(2) The airplanes identified in paragraph (c)(1) of this AD had passenger seats installed at manufacturer as listed in Embraer S.A. Service Bulletin (SB) No.: 500-25-0016, dated December 8, 2015; or Embraer S.A. SB No.: 505-25-0020, dated December 8, 2015. Since these are line replaceable units and the unsafe condition of this AD was originated during manufacturing, any passenger seat replaced with another one during routine maintenance is not affected by the actions of this AD.
Air Transport Association of America (ATA) Code 25: Equipment/Furnishing.
This AD was prompted by mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as incorrect installation of passenger seat attachment fittings. We are issuing this proposed AD to detect and correct improperly installed seat attachment fittings, which could result in seat damage causing injury to occupants during an emergency landing condition.
