We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 airplanes. This AD was prompted by numerous reports of failures of the proximity sensor within the slat skew detection mechanism assembly (DMA) leading to slats up landing events. This AD requires replacing the slat skew DMAs with new slat skew DMAs, and marking the existing identification plates on the slat with the new part number. We are issuing this AD to prevent failure of the proximity sensor, which could result in the slats being shut down and a slats up high speed landing. This condition, in combination with abnormal landing conditions such as a short runway or adverse weather conditions, could result in a runway excursion.

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
The Boeing Company Model 787-8 airplanes. This AD was prompted by 
numerous reports of failures of the proximity sensor within the slat 
skew detection mechanism assembly (DMA) leading to slats up landing 
events. This AD requires replacing the slat skew DMAs with new slat 
skew DMAs, and marking the existing identification plates on the slat 
with the new part number. We are issuing this AD to prevent failure of 
the proximity sensor, which could result in the slats being shut down 
and a slats up high speed landing. This condition, in combination with 
abnormal landing conditions such as a short runway or adverse weather 
conditions, could result in a runway excursion.

DATES: This AD is effective October 7, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of October 7, 
2015.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain The Boeing Company

[[Page 52940]]

Model 787-8 airplanes. The NPRM published in the Federal Register on 
November 28, 2014 (79 FR 70802). The NPRM was prompted by numerous 
reports of failures of the proximity sensor within the slat skew DMA 
leading to slats up landing events. The NPRM proposed to require 
replacing the slat skew DMAs with new slat skew DMAs, and marking the 
existing identification plates on the slat with the new part number. We 
are issuing this AD to prevent failure of the proximity sensor, which 
could result in the slats being shut down and a slats up high speed 
landing. This condition, in combination with abnormal landing 
conditions such as a short runway or adverse weather conditions, could 
result in a runway excursion.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM (79 
FR 70802, November 28, 2014) and the FAA's response to each comment.

Support for the NPRM (79 FR 70802, November 28, 2014)

    United Airlines (UAL) stated that it supports the NPRM (79 FR 
70802, November 28, 2014).

Requests To Correct the Location of the Part Numbers Affected

    Boeing and UAL requested a correction of the location of the 
identified part numbers affected in paragraphs (h)(2) and (h)(3) of the 
proposed AD (79 FR 70802, November 28, 2014). UAL stated that the part 
numbers affected in paragraphs (h)(2) and (h)(3) of the proposed AD are 
the wing leading edge slat assemblies, not the DMA. Boeing also 
commented that the part numbers are for a complete slat assembly 
(structure with DMA installed) and not just the DMA.
    We agree with the request. The intent of this AD is to prohibit 
installation of a defective slat skew DMA. Boeing Alert Service 
Bulletin B787-81205-SB270021-00, Issue 001, dated March 20, 2014, 
provides instructions to modify the existing slat assembly by replacing 
the defective slat skew DMA and then marking the existing slat assembly 
identification plate with a new part number. Therefore, we have revised 
paragraphs (h)(2) and (h)(3) of this AD to remove the text ``slat skew 
DMA in'' and just refer to the existing part numbers of the slat 
assembly, which contain the defective slat skew DMA.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this AD with the changes described previously and minor editorial 
changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (79 FR 70802, November 28, 2014) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (79 FR 70802, November 28, 2014).
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Alert Service Bulletin B787-81205-SB270021-00, 
Issue 001, dated March 20, 2014. The service information describes 
procedures for replacing the slat skew DMAs with new slat skew DMAs, 
and marking the existing identification plates on the slat with the new 
part number. 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 this 
AD.

Costs of Compliance

    We estimate that this AD affects 15 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

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.
