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 

reports of the accumulation of very fine 

particle deposits in the power control 

unit (PCU) electro-hydraulic servo 

valves (EHSVs) used in the flight control 

system; this accumulation caused 

degraded performance due to reduced 

EHSV internal hydraulic supply 

pressures, resulting in the display of 

PCU fault status messages from the 

engine indication and crew alerting 

system (EICAS). This AD requires 

installing markers to limit the hydraulic 

system fluid used to a specific brand, 

doing hydraulic fluid tests of the 

hydraulic systems, replacing hydraulic 

system fluid if necessary, and doing all 

applicable related investigative and 

corrective actions. We are issuing this 

AD to address the unsafe condition on 

these products. 

DATES: This AD is effective January 20, 

2017. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of January 20, 2017.

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 

August 19, 2015 (80 FR 50233) (‘‘the 

NPRM’’). The NPRM was prompted by 

reports of the accumulation of very fine 

particle deposits in the PCU EHSVs 

used in the flight control system; this 

accumulation caused degraded 

performance due to reduced EHSV 

internal hydraulic supply pressures, 

resulting in the display of PCU fault 

status messages from the EICAS. The 

NPRM proposed to require installing 

markers to limit the hydraulic system 

fluid used to a specific brand, doing 

hydraulic fluid tests of the hydraulic 

systems, replacing hydraulic system 

fluid if necessary, and doing all 

applicable related investigative and 

corrective actions. We are issuing this 

AD to prevent the failure of flight 

control hydraulic PCUs, which could 

lead to reduced controllability of the 

airplane. 

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. 

Request To Refer to Revised Service 

Information 

United Airlines (UAL) stated that 

there are many errors, omissions, and 

inconsistencies in Boeing Alert Service 

Bulletin B787–81205–SB270026–00, 

Issue 001, dated November 25, 2014, 

and provided examples of those 

mistakes. UAL asked that this service 

information be revised to correct these 

problems. 

Boeing has issued Boeing Alert 

Service Bulletin B787–81205– 

SB270026–00, Issue 002, dated June 13, 

2016. The revised service information 

corrects typographical errors and makes 

clarifications to the Accomplishment 

Instructions in Boeing Alert Service 

Bulletin B787–81205–SB270026–00, 

Issue 001, dated November 25, 2014. We 

have included Boeing Alert Service 

Bulletin B787–81205–SB270026–00, 

Issue 002, dated June 13, 2016, in 

paragraphs (c) and (h) of this AD. We 

have also included a new paragraph (i) 

in this AD to provide credit for actions 

done prior to the effective date of this 

AD using Boeing Alert Service Bulletin 

B787–81205–SB270026–00, Issue 001, 

dated November 25, 2014. The 

subsequent paragraphs have been 

redesignated accordingly. 

Request To Clarify the Reason for the 

Unsafe Condition 

Boeing asked that we remove all 

references to hydraulic fluid 

contamination causing EHSV 

restriction, in the SUMMARY, the 

Discussion section of the NPRM, and 

paragraph (e) of the proposed AD. 

Boeing stated that the issue is not 

hydraulic fluid contamination causing 

EHSV restriction, but the accumulation 

of very fine particle deposits within the 

EHSV causing degraded performance 

due to reduced EHSV internal hydraulic 

supply pressures. Boeing added that the 

solution is to change the hydraulic fluid 

to a specific brand, considering that it 

has been verified to significantly reduce 

the rate of accumulation of particles in 

the EHSVs. Boeing concluded that this 

would clarify the cause of the EICAS 

messages. 

We agree that the reason for the 

unsafe condition should be clarified, for 

the reasons provided. Therefore, we 

have removed the references to 

hydraulic fluid contamination causing 

EHSV restriction and replaced that 

language with a more accurate reason 

for the unsafe condition in the SUMMARY, 

the Discussion section of the final rule, 

and paragraph (e) of this AD.

90956 Federal Register / Vol. 81, No. 242 / Friday, December 16, 2016 / Rules and Regulations 

Request To Issue Global Alternative 

Method of Compliance (AMOC) 

UAL asked that a fleet-wide AMOC be 

issued for Boeing Service Bulletin 

B787–81205–SB290022–00, Issue 001, 

dated September 4, 2014, to correct a 

part number (P/N) reference. Task 1, 

Figure 1, and Task 2, Figure 1, of Boeing 

Service Bulletin B787–81205– 

SB290022–00, Issue 001, dated 

September 4, 2014, identify P/N 

710Z7290–9##ALT1 for the left and 

right engine diagonal braces; however, 

the correct P/N is 710Z7290–9 with no 

##ALT suffix. UAL stated that the 

correct part number is identified in the 

Illustrated Parts Catalog (IPC). 

We acknowledge the commenter’s 

concern that an incorrect part number 

for the left and right engine diagonal 

braces is identified in Boeing Service 

Bulletin B787–81205–SB290022–00, 

Issue 001, dated September 4, 2014. We 

have discussed this error with Boeing, 

and it was confirmed that the part 

number in the IPC (as noted by UAL) is 

correct and should be used. In light of 

this information, we do not agree that a 

global AMOC should be issued. 

However, we have added a new Note 2 

to paragraph (g) of this AD to clarify the 

correct part number. 

Request To Change Certain Instructions 

in the Service Information 

UAL stated that Boeing Service 

Bulletin B787–81205–SB290022–00, 

Issue 001, dated September 4, 2014, 

includes procedures for the HyJet V 

marker installation, which is a 

‘‘Required for Compliance (RC)’’ item in 

Boeing Alert Service Bulletin B787– 

81205–SB270026–00, Issue 001, dated 

November 25, 2014, and must be done 

before or concurrently with that service 

information. UAL noted that there is no 

RC language in Boeing Service Bulletin 

B787–81205–SB290022–00, Issue 001, 

dated September 4, 2014, which makes 

the entire service bulletin ‘‘RC.’’ UAL 

asked that the steps that specify access 

and close be marked as non-RC steps. 

We do not agree to change Boeing 

Service Bulletin B787–81205– 

SB290022–00, Issue 001, dated 

September 4, 2014, to mark the steps RC 

and non-RC. However, we do agree to 

clarify the steps that are required to 

accomplish the marker installation. 

Boeing Alert Service Bulletin B787– 

81205–SB270026–00, Issue 001, dated 

November 25, 2014, has an RC step that 

specifies to install markers. That RC 

step does not specify to perform access 

and close steps for the marker 

installation; therefore those access and 

close steps are not required by this AD. 

We have not changed this AD in this 

regard. 

UAL also asked we change the 

procedures in Part 4 of Boeing Alert 

Service Bulletin B787–81205– 

SB270026–00, Issue 001, dated 

November 25, 2014, which specify 

options for either replacing the 

hydraulic fluid again, or draining and 

filling the hydraulic reservoir. UAL 

stated that if either option is used, then 

Part 2 of the service information titled 

‘‘Cycle Hydraulic Fluid’’ must again be 

done, or the airplane must be flown at 

least one flight cycle, and then a sample 

drawn for testing. UAL added that this 

procedure, done in accordance with the 

instructions in the referenced service 

information, results in excessive cycling 

if the operator needs to only replace a 

small amount of fluid and chooses the 

reservoir drain-and-fill option. UAL 

asked to use a procedure that would 

specify draining and filling the 

reservoir, flight control cycling, and 

taking a fresh sample for testing, all at 

the same time. UAL noted that Option 

10 specifies ‘‘Drain and Fill Hydraulic 

Reservoir’’ and is acceptable to operate 

the flight controls six to eight times to 

let the fluid flow through all the 

systems. UAL stated that this is the 

procedure used by Boeing before taking 

fluid samples per the Boeing 787 

Airplane Maintenance Manual. 

We do not agree to change the 

procedure for servicing the hydraulic 

fluid. Although UAL’s proposal is an 

accepted procedure in the Boeing 787 

Airplane Maintenance Manual, this 

procedure does not include operating 

the other hydraulic-powered 

subsystems, such as the landing gear, 

thrust reverser, and brakes. 

Subsequently, it could result in stagnant 

fluid measurements not intermixing 

with other hydraulic system fluid 

following replacement of the hydraulic 

system fluid, and could generate fluid 

test samples that do not include the 

entire system. In light of these factors, 

we have not changed this AD in this 

regard. 

Clarification to Paragraph (g) of This 

AD 

We have added a new Note 1 to 

paragraph (g) of this AD to refer to 

Boeing Service Bulletin B787–81205– 

SB290022–00, Issue 001, dated 

September 4, 2014, as an additional 

source of guidance for installing 

markers to allow servicing of hydraulic 

systems with only HyJet V hydraulic 

fluid. 

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 for 

correcting the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM. 

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 have reviewed Boeing Alert 

Service Bulletin B787–81205– 

SB270026–00, Issue 002, dated June 13, 

2016. This service information describes 

procedures for installing markers to 

limit the hydraulic system fluid used to 

a specific brand; doing hydraulic fluid 

tests of the hydraulic systems, replacing 

the hydraulic system fluid if necessary, 

and related investigative 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. 

Costs of Compliance 

We estimate that this AD affects 11 

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 

Install markers ................................................. 2 work-hours × $85 per hour = $170 ............. $95 $265 $2,915 

Test and replace left, center, and right hydraulic system fluid.104 work-hours × $85 per hour = $8,840 ...... 1,020 9,860 108,460 


asabaliauskas on DSK3SPTVN1PROD with RULES
Federal Register / Vol. 81, No. 242 / Friday, December 16, 2016 / Rules and Regulations 90957 

We estimate the following costs to do 

any necessary replacements that may be 

required based on the results of the 

inspection. We have no way of 

determining the number of aircraft that 

might need these replacements: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

product 

Replace power control unit of elevator ........................ 9 × $85 per hour = $765 .............................................. $108,000 $108,765 

Replace power control unit of aileron .......................... 9 × $85 per hour = $765 .............................................. 118,000 118,765 

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 

(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.
