SUPPLEMENTARY INFORMATION: Airworthiness Directive 2016-25-02 (81 FR 
90955, December 16, 2016), 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 for certain The Boeing Company Model 787-8 
airplanes.

Need for the Correction

    As published, the amendment number specified in the preamble and 
regulatory text is incorrect. The incorrectly specified number was 
Amendment 39-18725; the correct number is Amendment 39-18728.

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.

Correction of Publication

    This document corrects an error and correctly adds the AD as an 
amendment to 14 CFR 39.13. Although no other part of the preamble or 
regulatory information has been corrected, we are publishing the entire 
rule in the Federal Register.
    The effective date of this AD remains January 20, 2017.
    Since this action only corrects an amendment number, it has no 
adverse economic impact and imposes no additional burden on any person. 
Therefore, we have determined that notice and public procedures are 
unnecessary.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

Adoption of the Correction

    Accordingly, pursuant to the authority delegated to me by the 
Administrator, the Federal Aviation Administration amends part 39 of 
the Federal Aviation Regulations (14 CFR part 39) as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13   [Corrected]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2016-25-02 The Boeing Company: Amendment 39-18728; Docket No. FAA-
2015-3142; Directorate Identifier 2015-NM-003-AD.

(a) Effective Date

    This AD is effective January 20, 2017.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to The Boeing Company Model 787-8 series 
airplanes, certificated in any category, as identified in Boeing 
Alert Service Bulletin B787-81205-SB270026-00, Issue 002, dated June 
13, 2016.

(d) Subject

    Air Transport Association (ATA) of America Code 27, Flight 
Control Systems.

(e) Unsafe Condition

    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). We are issuing this AD to prevent failure of flight 
control hydraulic PCUs, which could lead to reduced controllability 
of the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Marker Installation

    Within 36 months after the effective date of this AD, install 
markers to allow servicing

[[Page 96362]]

of hydraulic systems with only HyJet V hydraulic fluid, in 
accordance with the Accomplishment Instructions of Boeing Alert 
Service Bulletin B787-81205-SB270026-00, Issue 002, dated June 13, 
2016.

    Note 1 to paragraph (g) of this AD:  Boeing Alert Service 
Bulletin B787-81205-SB270026-00, Issue 002, dated June 13, 2016, 
refers 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.


    Note 2 to paragraph (g) of this AD: 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.

(h) Fluid Tests of the Left, Right, and Center Hydraulic Systems

    For airplanes identified in Boeing Alert Service Bulletin B787-
81205-SB270026-00, Issue 002, dated June 13, 2016, as Group 1, 
Configuration 2, Group 2: Within 36 months after the effective date 
of this AD, do hydraulic fluid tests of the left, right, and center 
hydraulic systems, replace the hydraulic system fluid, if necessary, 
and do all applicable related investigative and corrective actions, 
in accordance with the Accomplishment Instructions of Boeing Alert 
Service Bulletin B787-81205-SB270026-00, Issue 002, dated June 13, 
2016. Do all applicable related investigative and corrective actions 
within 36 months after the effective date of this AD.

(i) Credit for Previous Actions

    This paragraph provides credit for the actions required by 
paragraphs (g) and (h) of this AD, if those actions were performed 
before the effective date of this AD using Boeing Alert Service 
Bulletin B787-81205-SB270026-00, Issue 001, dated November 25, 2014.

(j) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Seattle Aircraft Certification Office (ACO), 
FAA, has the authority to approve AMOCs for this AD, if requested 
using the procedures found in 14 CFR 39.19. In accordance with 14 
CFR 39.19, send your request to your principal inspector or local 
Flight Standards District Office, as appropriate. If sending 
information directly to the manager of the ACO, send it to the 
attention of the person identified in paragraph (k)(1) of this AD. 
Information may be emailed to: <a href="/cdn-cgi/l/email-protection#764f5b37383b5b25131702021a135b3735395b373b39355b24130703130502053610171758111900"><span class="__cf_email__" data-cfemail="a49d89e5eae989f7c1c5d0d0c8c189e5e7eb89e5e9ebe789f6c1d5d1c1d7d0d7e4c2c5c58ac3cbd2">[email&#160;protected]</span></a>.
    (2) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the local flight standards district office/certificate holding 
district office.
    (3) For service information that contains steps that are labeled 
as Required for Compliance (RC), the provisions of paragraphs 
(j)(3)(i) and (j)(3)(ii) apply.
    (i) 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. If a step or sub-step is labeled ``RC Exempt,'' then 
the RC requirement is removed from that step or sub-step. An AMOC is 
required for any deviations to RC steps, including substeps and 
identified figures.
    (ii) 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.
    (4) An AMOC that provides an acceptable level of safety may be 
used for any repair required by this AD if it is approved by the 
Boeing Commercial Airplanes Organization Designation Authorization 
(ODA) that has been authorized by the Manager, Seattle ACO, to make 
those findings. For a repair method to be approved, the repair must 
meet the certification basis of the airplane, and the approval must 
specifically refer to this AD.
