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 all The Boeing 
Company Model 777 airplanes. Paragraph (i)(4) of the regulatory text 
contains a reference to a nonexistent paragraph. This

document corrects that error. In all other respects, the original 
document remains the same.

DATES: This final rule is effective January 28, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of January 28, 
2016 (80 FR 80234, December 24, 2015).

ADDRESSES: For service information identified in this final rule,

SUPPLEMENTARY INFORMATION: Airworthiness Directive 2015-25-08, 
Amendment 39-18346 (80 FR 80234, December 24, 2015), currently requires 
repetitive inspections for any crack in the aft webs of the radial lap 
splices of the aft pressure bulkhead, and, if necessary, corrective 
actions, for all The Boeing Company Model 777 airplanes.

Need for the Correction

    As published, paragraph (i)(4) of the regulatory text contains a 
reference to a nonexistent paragraph. Paragraph (i)(4) of the AD 
incorrectly references paragraph ``(l)(4)(ii)''; however, the correct 
reference is paragraph ``(i)(4)(ii).''

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Alert Service Bulletin 777-53A0078, dated 
December 5, 2014. This service information describes procedures for 
inspections of the lap splices in the web of the aft pressure bulkhead 
for cracking, 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 section 39.13 of the Federal Aviation Regulations (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 28, 2016.
    Since this action only corrects a paragraph reference, 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

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):

2015-25-08 The Boeing Company: Amendment 39-18346; Docket No. FAA-
2015-1281; Directorate Identifier 2014-NM-241-AD.

(a) Effective Date

    This AD becomes effective on January 28, 2016.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to all The Boeing Company Model 777-200, -200LR, 
-300, -300ER, and 777F series airplanes, certificated in any 
category.

(d) Subject

    Air Transport Association (ATA) of America Code 53, Fuselage.

(e) Unsafe Condition

    This AD was prompted by an evaluation by the design approval 
holder indicating that the lap splices of the aft pressure bulkhead 
webs are subject to widespread fatigue damage on aging Model 777 
airplanes that have accumulated at least 38,000 total flight cycles. 
We are issuing this AD to detect and correct fatigue cracking in the 
aft webs of the radial lap splices of the aft pressure bulkhead; 
such cracking could result in reduced structural integrity of the 
airplane, decompression of the cabin, and collapse of the floor 
structure.

(f) Compliance

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

(g) Inspection of Lap Splice in the Web of the Aft Pressure Bulkhead

    Except as required by paragraph (h) of this AD: At the times 
specified in paragraph 1.E., ``Compliance,'' of Boeing Alert Service 
Bulletin 777-53A0078, dated December 5, 2014, do a medium frequency 
eddy current inspection for any cracking in the aft webs of the 
radial lap splices of the aft pressure bulkhead, in accordance with 
the Accomplishment Instructions of Boeing Alert Service Bulletin 
777-53A0078, dated December 5, 2014. Repeat the inspection 
thereafter at intervals not to exceed 8,400 flight cycles from the 
previous inspection. If any crack is found during any inspection 
required by this AD, do the applicable corrective actions, in 
accordance with the Accomplishment Instructions of Boeing Alert 
Service Bulletin 777-53A0078, dated December 5, 2014. If a 
corrective action described in Boeing Alert Service Bulletin 777-
53A0078, dated December 5, 2014, specifies to contact Boeing for 
appropriate action: Before further flight, repair using a method 
approved in accordance with the procedures specified in paragraph 
(i) of this AD.

(h) Exception to Service Information Specifications

    Where Boeing Alert Service Bulletin 777-53A0078, dated December 
5, 2014, specifies a compliance time ``after the original issue date 
of this service bulletin,'' this AD requires compliance within the 
specified compliance time after the effective date of this AD.

(i) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Seattle Aircraft Certification Office (ACO), 
FAA, has the authority to approve AMOCs for this AD, if

[[Page 4165]]

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 (j) 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, 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.
    (4) For service information that contains steps that are labeled 
as Required for Compliance (RC), the provisions of paragraphs 
(i)(4)(i) and (i)(4)(ii) of this AD 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. 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.
