14 CFR Part 39

39-19540; AD 2019-01-01]

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; correction.

-----------------------------------------------------------------------

SUMMARY: The FAA is correcting an airworthiness directive (AD) that 
published in the Federal Register. That AD applies to The Boeing 
Company Model 787-8 airplanes powered by Rolls-Royce plc (RR) Trent 
1000-A (including -A/01 and -A/01A), Trent 1000-AE (including -AE/01A), 
Trent 1000-C (including -C/01 and -C/01A), Trent 1000-CE (including -
CE/01A), Trent 1000-D (including -D/01 and -D/01A), Trent 1000-E 
(including -E/01 and -E/01A), Trent 1000-G (including -G/01 and -G/
01A), and Trent 1000-H (including -H/01 and H/01A) turbofan engines. As 
published, a document referenced in the regulatory text was incorrectly 
identified. This document corrects that error. In all other respects, 
the original document remains the same.

DATES: This correction is effective February 4, 2019.

ADDRESSES:

SUPPLEMENTARY INFORMATION: As published, Airworthiness Directive 2019-
01-01, Amendment 39-19540 (84 FR 129, January 18, 2019) (``AD 2019-01-
01''), requires revising the airplane flight manual (AFM) to limit 
extended operations (ETOPS) for The Boeing Company Model 787-8 
airplanes powered by RR Trent 1000-A (including -A/01 and -A/01A), 
Trent 1000-AE (including -AE/01A), Trent 1000-C (including -C/01 and -
C/01A), Trent 1000-CE (including -CE/01A), Trent 1000-D (including -D/
01 and -D/01A), Trent 1000-E (including -E/01 and -E/01A), Trent 1000-G 
(including -G/01 and -G/01A), and Trent 1000-H (including -H/01 and H/
01A) turbofan engines.

Need for the Correction

    As published, a document specified in the regulatory text is 
incorrect. Specifically, a service bulletin that is referenced in 
figure 1 to paragraph (g) of AD 2019-01-01 was incorrectly identified 
as Rolls Royce Non Modification Service Bulletin Trent 1000 ``72-
AK132.'' The correct number is ``72-K132.'' Service bulletin ``72-
AK132'' does not exist, and therefore, operators cannot directly comply 
with the AD requirement that refers to that service bulletin.

Correction of Publication

    The error appeared in figure 1 to paragraph (g) of AD 2019-01-01. 
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 February 4, 2019.

List of Subjects in 14 CFR Part 39

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):

2019-01-01 The Boeing Company: Amendment 39-19540; Docket No. FAA-
2018-1066; Product Identifier 2018-NM-176-AD.

(a) Effective Date

    This AD is effective February 4, 2019.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to The Boeing Company Model 787-8 airplanes, 
certificated in any category, powered by Rolls-Royce plc (RR) Trent 
1000-A (including -A/01 and -A/01A), Trent 1000-AE (including -AE/
01A), Trent 1000-C (including -C/01 and -C/01A), Trent 1000-CE 
(including -CE/01A), Trent 1000-D (including -D/01 and -D/01A), 
Trent 1000-E (including -E/01 and -E/01A), Trent 1000-G (including -
G/01 and -G/01A), and Trent 1000-H (including -H/01 and H/01A) 
turbofan engines.

(d) Subject

    Air Transport Association (ATA) of America Code 71, Power plant.

(e) Unsafe Condition

    This AD was prompted by a report from the engine manufacturer 
indicating that after an engine failure, prolonged operation at high 
thrust settings on the remaining engine during an extended-operation 
(ETOPS) diversion may result in failure of the remaining engine 
before the diversion can be safely completed. We are issuing this AD 
to address unrecoverable thrust loss on both engines, which could 
lead to a forced landing.

(f) Compliance

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

(g) Revision of Limitations Chapter in Airplane Flight Manual (AFM)

    Within 7 days after the effective date of this AD, revise the 
Certificate Limitations chapter of the applicable Boeing AFM Engine 
Appendix by incorporating the information in figure 1 to paragraph 
(g) of this AD. This may be accomplished by inserting a copy of this 
AD into the AFM. When information identical to that in figure 1 to 
paragraph (g) of this AD has been included in the Certificate 
Limitations chapter of the general revisions of the AFM, the general 
revisions may be inserted into the AFM, and the copy of this AD may 
be removed from the AFM.

    Note 1 to paragraph (g) of this AD: The Boeing AFM for the 
aircraft affected by this

[[Page 444]]

AD is required to be furnished with the aircraft, per 14 CFR 
25.1581. Further, operators of the aircraft affected by this AD must 
operate in accordance with the limitations specified in the AFM, per 
14 CFR 91.9.

(h) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Seattle ACO Branch, 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 certification office, send it to the attention of the 
person identified in paragraph (i) of this AD. Information may be 
emailed to: 9-ANM-Seattle-ACO-AMOC-Requests@faa.gov.
    (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) An AMOC that provides an acceptable level of safety may be 
used for any repair, modification, or alteration 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 Branch, to make those findings. To be approved, 
the repair method, modification deviation, or alteration deviation 
must meet the certification basis of the airplane, and the approval 
must specifically refer to this AD.
