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 


asabaliauskas on DSK5VPTVN1PROD with RULES
52940 Federal Register / Vol. 80, No. 170 / Wednesday, September 2, 2015 / Rules and Regulations 

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: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Replacement ........................... 11 work-hours X $85 per hour = $935 ................................... $0 $935 $14,025 

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.

ACTION: Final rule; request for

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all 

Lockheed Martin Corporation/Lockheed 

Martin Aeronautics Company Model 

382, 382B, 382E, 382F, and 382G 

airplanes. This AD requires replacing 

the center wing box (CWB) and certain 

outer wings. This AD was prompted by 

an evaluation by the design approval 

holder (DAH) indicating that the CWB 

and outer wings are subject to 

widespread fatigue damage (WFD). We 

are issuing this AD to prevent fatigue 

cracking of the outer wings and the 

lower surface of the CWB, which could 

result in reduced structural integrity of 

the airplane. 

DATES: This AD is effective September 

17, 2015. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of September 17, 2015. 

We must receive comments on this 

AD by October 19, 2015. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following
