Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 787–8 

airplanes. This proposed AD was 

prompted by reports of hydraulic 

contamination of the power control unit 

(PCU) electro-hydraulic servo valves 

(EHSVs) used in the flight control 

system; this contamination caused a 

restriction in the EHSVs resulting in the 

display of status messages from the 

engine indication and crew alerting 

system (EICAS). This proposed AD 

would 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 

proposing this AD to prevent the failure 

of flight control hydraulic PCUs, which 

could lead to reduced controllability of 

the airplane. 

DATES: We must receive comments on 

this proposed AD by October 5, 2015. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

about this proposed AD. 

Discussion 

We received reports of the display of 

status messages from the engine 

indication and crew alerting system 

(EICAS). Boeing and the actuation 

system supplier determined these 

messages are displayed when electrohydraulic servo valves (EHSVs) of the 

power control units (PCUs) of the 

primary flight control system are 

restricted due to the accumulation of 

particle deposits. Failures have only 

occurred on airplanes operated with 

Skydrol LD–4 hydraulic fluid. Changing 

the hydraulic fluid to HyJet V would 

reduce the rate of particle deposit 

accumulation. This condition, if not 

corrected, could result in the eventual 

failure of flight control hydraulic PCUs, 

which could lead to reduced 

controllability of the airplane. 

Related Service Information Under 1 

CFR Part 51 

We reviewed Boeing Alert Service 

Bulletin B787–81205–SB270026–00, 

Issue 001, dated November 25, 2014. 

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 of this NPRM. 

FAA’s Determination 

We are proposing 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. 

Proposed AD Requirements 

This proposed AD would require 

accomplishing the actions specified in 

the service information described 

previously. Refer to this service 

information for details on the 

procedures and compliance times. 

The phrase ‘‘related investigative 

actions’’ is used in this proposed AD. 

‘‘Related investigative actions’’ are 

follow-on actions that (1) are related to 

the primary actions, and (2) further 

investigate the nature of any condition 

found. Related investigative actions in 

an AD could include, for example, 

inspections. 

The phrase ‘‘corrective actions’’ is 

used in this proposed AD. ‘‘Corrective 

actions’’ are actions that correct or 

address any condition found. Corrective 


rmajette on DSK2VPTVN1PROD with PROPOSALS
50234 Federal Register / Vol. 80, No. 160 / Wednesday, August 19, 2015 / Proposed Rules 

actions in an AD could include, for 

example, repairs. 

Explanation of ‘‘RC’’ Steps in Service 

Information 

The FAA worked in conjunction with 

industry, under the Airworthiness 

Directive Implementation Aviation 

Rulemaking Committee (ARC), to 

enhance the AD system. One 

enhancement was a new process for 

annotating which steps in the service 

information are required for compliance 

with an AD. Differentiating these steps 

from other tasks in the service 

information is expected to improve an 

owner’s/operator’s understanding of 

crucial AD requirements and help 

provide consistent judgment in AD 

compliance. The steps identified as RC 

(required for compliance) in any service 

information identified previously have a 

direct effect on detecting, preventing, 

resolving, or eliminating an identified 

unsafe condition. 

For service information that contains 

steps that are labeled as Required for 

Compliance (RC), the following 

provisions apply: (1) The steps labeled 

as RC, including substeps under an RC 

step and any figures identified in an RC 

step, must be done to comply with the 

AD, and an AMOC is required for any 

deviations to RC steps, including 

substeps and identified figures; and (2) 

steps not labeled as RC may be deviated 

from using accepted methods in 

accordance with the operator’s 

maintenance or inspection program 

without obtaining approval of an 

AMOC, provided the RC steps, 

including substeps and identified 

figures, can still be done as specified, 

and the airplane can be put back in an 

airworthy condition. 

Costs of Compliance 

We estimate that this proposed AD 

affects 11 airplanes of U.S. registry. 

We estimate the following costs to 

comply with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Installing 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 

We estimate the following costs to do 

any necessary replacements that would 

be required based on the results of the 

proposed 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 proposed 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 

We determined that this proposed AD 

would not have federalism implications 

under Executive Order 13132. This 

proposed AD would 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 this proposed regulation: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Is not a ‘‘significant rule’’ under 

the 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.
