Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

SUMMARY: We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 and 787-9 airplanes. This AD requires repetitive inspections of the bilge barriers located in the forward and aft cargo compartments for disengaged decompression panels, and reinstalling any disengaged panels. This AD was prompted by several reports of disengaged decompression panels found on in-service airplanes. We are issuing this AD to detect and correct disengaged decompression panels from the bilge barriers located in the forward and aft cargo compartments. In the event of a cargo compartment fire, this condition would provide a path for smoke and Halon to enter the flight compartment and passenger cabin, which could result in the inability to contain and extinguish a fire.

DATES: This AD is effective May 23, 2016.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of May 23, 2016.

We must receive comments on this AD by June 20, 2016.

SUPPLEMENTARY INFORMATION:

Discussion

We have received several reports of disengaged decompression panels found on in-service airplanes. It appears these decompression panels disengaged prior to delivery, during test flights. Tests done by the airplane manufacturer revealed some decompression panels disengage at a pressure differential below the design/intended value. This condition, if not corrected, would provide a path for smoke and Halon to enter the flight compartment and passenger cabin in the event of a cargo compartment fire, which could result in the inability to contain and extinguish a fire.

Related Service Information Under 1 CFR Part 51

We reviewed Boeing Alert Service Bulletin B787-81205-SB500009-00, Issue 001, dated November 16, 2015. The service information describes procedures for repetitive inspections of the bilge barriers located in the forward and aft cargo compartments for disengaged decompression panels, and reinstalling any disengaged panels. 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

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.

AD Requirements

This AD requires accomplishing the actions specified in the service information described previously.

For information on the procedures and compliance times, see this service information at http://www.regulations.gov by searching for and locating Docket No. FAA-2016-6149.

Interim Action

We consider this AD interim action. The airplane manufacturer is currently developing a modification that will address the unsafe condition identified in this AD. Once this modification is developed, approved, and available, we might consider additional rulemaking.

FAA's Justification and Determination of the Effective Date

An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because if any decompression panel is disengaged from the bilge barriers located in the forward and aft cargo compartments and a cargo compartment fire were to occur, the fire could not be contained or extinguished. Therefore, we find that notice and opportunity for prior public comment are impracticable and that good cause exists for making this amendment effective in less than 30 days.

Comments Invited

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 the docket number FAA-2016-6149 and Directorate Identifier 2016-NM-047-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.

Costs of Compliance

We estimate that this AD affects 42 airplanes of U.S. registry. We estimate the following costs to comply with this AD:

Estimated Costs

--------------------------------------------------------------------------------------------------------------------------------------------------------

Action Labor cost Parts cost Cost per product Cost on U.S. operators

--------------------------------------------------------------------------------------------------------------------------------------------------------

Inspection............................ 3 work-hours x $85 per $0 $255 per inspection $10,710 per inspection cycle.

----------------------------------------------------------------------------------------------------------------

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

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.
