We have received reports of missing right and left outboard partition tie rods at station 337 (door number 1) on Model 787-8 airplanes as a result of a manufacturing escape ( i.e., insufficient documentation to show engineering details). We are issuing this AD to detect and correct partitions with missing tie rods or release pins or with supports that are not engaged in the structural bracket. These partitions could come loose during a high-acceleration event and strike the flight attendant seats in the door 1 location, causing serious injury to the seat occupants, or could affect safe egress from the airplane.

We reviewed Boeing Service Bulletin B787-81205-SB250081-00, Issue 001, dated December 9, 2014. The service bulletin describes procedures for an inspection of the station 337 outboard partitions for a tie rod and quick release pins, and also to determine that both partition supports are engaged in the structural bracket, and corrective actions. 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.

We are issuing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design.

This AD requires accomplishing the actions specified in the service information described previously, except as discussed under “Differences Between the AD and the Service Information.”

The phrase “corrective actions” is used in this AD. “Corrective actions” are actions that correct or address any condition found. Corrective actions in an AD could include, for example, repairs.

Boeing Service Bulletin B787-81205-SB250081-00, Issue 001, dated December 9, 2014, specifies to do the general visual inspection “in accordance with the Tasks in Table 6” of the service information. However “Table 6” does not exist. The tasks are identified in Table 4 of the service information. Therefore, this AD requires that the inspection be done in accordance with the tasks in Table 4 of the Accomplishment Instructions of Boeing Service Bulletin B787-81205-SB250081-00, Issue 001, dated December 9, 2014.

Since there are currently no domestic operators of this product, we find that notice and opportunity for prior public comment are unnecessary and that good cause exists for making this amendment effective in less than 30 days.

This AD is a final rule that involves requirements affecting flight safety and was not preceded by notice and an opportunity for public comment. However, we invite you to send any written data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include “Docket Number FAA-2016-3981; Directorate Identifier 2015-NM-053-AD” at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those comments.

We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD.

We estimate that this AD affects 0 airplanes of U.S. registry.

We estimate the following costs to comply with this AD:

We estimate the following costs to do any necessary repairs that would be required based on the results of the inspection. We have no way of determining the number of aircraft that might need these repairs:

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.

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 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 that this AD:

(1) Is not a “significant regulatory action” under Executive Order 12866,

(2) Is not a “significant rule” under 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.

Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:

1. The authority citation for part 39 continues to read as follows:

2. The FAA amends § 39.13 by adding the following new airworthiness directive (AD):
