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 777–200 

and –300 series airplanes equipped with 

Pratt and Whitney engines. This AD was 

prompted by reports of blocked drain 

lines at the engine forward strut that 

caused flammable fluid to accumulate 

in a flammable leakage zone. This AD 

requires doing the following actions on 

the left strut and right strut: A one-time 

cleaning of certain forward strut drain 

lines; installing new forward strut drain 

lines and insulation blankets; a leak 

check of the forward strut drain lines; 

and repair if any leak is found. This AD 

also requires revising the maintenance 

or inspection program, as applicable, to 

incorporate a certain airworthiness 

limitation. We are issuing this AD to 

prevent blockage of forward strut drain 

lines. This condition could cause 

flammable fluids to collect in the 

forward strut area and potentially cause 

an uncontrolled fire or cause failure of 

engine attachment structure and 

consequent airplane loss. 

DATES: This AD is effective July 12, 

2016. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of July 12, 2016.

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 

Model 777–200 and –300 series 

airplanes equipped with Pratt and 

Whitney engines. The NPRM published 

in the Federal Register on December 31, 

2015 (80 FR 81788) (‘‘the NPRM’’). The 

NPRM was prompted by reports of 

blocked drain lines at the engine 

forward strut that caused flammable 

fluid to accumulate in a flammable 

leakage zone. The NPRM proposed to 

require doing the following actions on 

the left strut and right strut: A one-time 

cleaning of certain forward strut drain 

lines; installing new forward strut drain 

lines and insulation blankets; a leak 

check of the forward strut drain lines; 

and repair if any leak is found. The 

NPRM also proposed to require revising 

the maintenance or inspection program, 

as applicable, to incorporate a certain 

airworthiness limitation. We are issuing 

this AD to prevent blockage of forward 

strut drain lines. This condition could 

cause flammable fluids to collect in the 

forward strut area and potentially cause 

an uncontrolled fire or cause failure of 

engine attachment structure and 

consequent airplane loss. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the NPRM. 

Support for the NPRM 

Boeing, United Airlines, and Airline 

Pilots Association International have no 

objections to the NPRM. 

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting this AD 

as proposed, except for 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. 

Related Service Information Under 1 

CFR Part 51 

We reviewed the following service 

information: 

• Boeing Special Attention Service 

Bulletin 777–54–0028, Revision 1, dated 

December 10, 2013. This service 

information describes procedures for a 

general visual inspection for hydraulic 

fluid contamination of the interior of the 

strut forward dry bay and corrective 

actions. 

• Boeing Special Attention Service 

Bulletin 777–71–0055, Revision 1, dated 

April 15, 2015. The service information 

describes procedures for installing new 

forward strut drain lines and insulation 

blankets on the left and right engines. 

• Airworthiness Limitation 54–AWL– 

01, ‘‘Forward Strut Drain Line,’’ as 

specified in Section D.4, Pratt and 

Whitney Forward Strut Drain Line, 

dated March 2014, of the Boeing 777 

Maintenance Planning Data (MPD) 

Document Section 9, Airworthiness 

Limitations (AWLs) and Certification 

Maintenance Requirements (CMRs), 

D622W001–9, dated October 2014. This 

service information describes an 

airworthiness limitation task for the 

functional check of the forward strut 

drain line. 

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. 

Costs of Compliance 

We estimate that this AD affects 54 

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 

Cleaning strut drain lines, installing new drain lines and insulation blankets, doing a leak check, and revising the maintenance or inspection program.16 work-hours × $85 per hour 

= $1,360.

$17,080 $18,440 $995,760 

We have received no definitive data 

that will enable us to provide cost 

estimates for the on-condition actions 

specified in this AD. 

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. 

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 


jstallworth on DSK7TPTVN1PROD with RULES
Federal Register / Vol. 81, No. 109 / Tuesday, June 7, 2016 / Rules and Regulations 36451 

(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.

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 a 

report of wire chafing caused by a left 

wing spoiler actuator wire not having 

enough separation from a certain 

bracket when the spoiler is in the 

deployed position. This AD requires 

measuring the separation between a 

certain electro-mechanical actuator wire 

of the left wing, spoiler 4, and the 

support bracket of the flap variable 

camber trim unit; and related 

investigative and corrective actions if 

necessary. We are issuing this AD to 

detect and correct wire chafing. Such 

chafing could result in an electrical 

short and potential fire in a flammable 

fluid leakage zone and possible loss of 

several functions essential for safe 

flight. 

DATES: This AD is effective July 12, 

2016. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of July 12, 2016.

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 

Model 787–8 airplanes. The NPRM 

published in the Federal Register on 

October 19, 2015 (80 FR 63132) (‘‘the 

NPRM’’). The NPRM was prompted by 

a report of insufficient clearance and 

wire chafing between the wiring to the 

number 4 spoiler electro-mechanical 

actuator and a bracket of the flap 

variable camber trim unit with the 

spoiler fully deployed. The NPRM 

proposed to require measuring the 

separation between a certain electromechanical actuator wire of the left 

wing, spoiler 4, and the support bracket 

of the flap variable camber trim unit, 

and related investigative and corrective 

actions if necessary. We are issuing this 

AD to detect and correct wire chafing. 

Such chafing could result in an 

electrical short and potential fire in a 

flammable fluid leakage zone and 

possible loss of several functions 

essential for safe flight. 

Comments 

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. 

Support for the NPRM 

United Airlines stated that it agrees 

with the NPRM, has completed the 

actions specified in Boeing Alert Service 

Bulletin B787–81205–SB270024–00, 

Issue 001, dated September 24, 2014, 

and has no technical findings/issues to 

report.
