[Docket No. FAA-2010-1160; Directorate Identifier 2010-NM-148-AD]
RIN 2120-AA64


Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Supplemental notice of proposed rulemaking (SNPRM); reopening 
of comment period.

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

SUMMARY: We are revising an earlier proposed airworthiness directive 
(AD) to supersede an existing AD for certain The Boeing Company Model 
767 airplanes. The existing AD currently requires repetitive 
inspections to detect discrepancies of the wiring and surrounding 
Teflon sleeves of the fuel tank boost pumps and override/jettison 
pumps; replacement of the sleeves with new sleeves, for certain 
airplanes; and repair or replacement of the wiring and sleeves with new 
parts, as necessary. The first SNPRM proposed to reduce the initial 
compliance time and repetitive inspection interval in the existing AD. 
The first SNPRM also proposed to mandate a terminating action for the 
repetitive inspections, to eliminate wire damage. In addition, the 
first SNPRM proposed to remove certain airplanes from the applicability 
of the existing AD. The first SNPRM was prompted by fleet information 
indicating that the repetitive inspection interval in the existing AD 
is too long, because excessive chafing of the sleeving continues to 
occur much earlier than expected between scheduled inspections. This 
action revises the first SNPRM by also proposing to require revising 
the maintenance program to incorporate changes to the airworthiness 
limitations section. We are proposing this second SNPRM to detect and 
correct chafing of the fuel pump wire insulation and consequent 
exposure of the electrical conductor, which could result in electrical 
arcing between the wires and conduit and consequent fire or explosion 
of the fuel tank. Since these actions impose an additional burden over 
that proposed in the first SNPRM, we are reopening the comment period 
to allow the public the chance to comment on these proposed changes.

DATES: We must receive comments on this proposed AD by April 22, 2013.

Discussion

    We issued a supplemental notice of proposed rulemaking (SNPRM) to 
amend 14 CFR part 39 to supersede airworthiness directive (AD) 2000-11-
06, Amendment 39-11754 (65 FR 34928, June 1, 2000; corrected August 1, 
2000 (65 FR 46862)). That first SNPRM would apply to certain Model 767-
200, -300, -300F, and -400ER series airplanes. The first SNPRM 
published in the Federal Register on July 2, 2012 (77 FR 39188). The 
first SNPRM proposed to continue to require repetitive inspections to 
detect discrepancies of the wiring and surrounding Teflon sleeves of 
the fuel tank boost pumps and override/jettison pumps; replacement of 
the sleeves with new sleeves, for certain airplanes; and repair or 
replacement of the wiring and sleeves with new parts, as necessary. The 
first SNPRM also proposed to reduce the initial compliance time and 
repetitive inspection interval in the existing AD, and remove certain 
airplanes from the applicability of the existing AD. In addition, the 
first SNPRM proposed to include a terminating action for the

[[Page 14935]]

repetitive inspections, to eliminate wire damage.

Actions Since First SNPRM Was Issued

    Since we issued the first SNPRM (77 FR 39188, July 2, 2012), we 
have reviewed the information specified in Airworthiness Limitation 
Instruction, Critical Design Configuration Control Limitations (CDCCL) 
Task 28-AWL-29, ``In-Tank AC Fuel Pump Wire Bundles with Protective 
Liner;'' and CDCCL Task 28-AWL-30, ``Fuel Boost Pump Wires in Conduit 
Installation--In Fuel Tank;'' of Section 9 of Boeing 767 Airworthiness 
Limitations (AWLs) and Certification Maintenance Requirements (CMRs), 
D622T001-9, Revision October 2012. We have determined it is necessary 
to revise the maintenance program to include these tasks in order to 
address the identified unsafe condition.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the proposal 
(77 FR 39188, July 2, 2012), and the FAA's response to each comment.

Request To Change Terminating Action Requirement

    Air Canada (ACN) asked that the terminating action mandated by the 
first SNPRM (77 FR 39188, July 2, 2012) be deemed optional. American 
Airlines (AAL) stated that after complying with the inspections in the 
first SNPRM, very little damage was found. AAL added that damage is 
confined to the outer sleeve beyond 44,400 flight hours, and the wiring 
damage does not occur until 17 years later when undisturbed. AAL 
concluded that, given its service experience, Boeing's service data and 
analysis and the proposed 15,000 flight-hour inspection interval, the 
terminating action should not be mandated. ACN provided no 
justification for its request.
    We do not agree with the commenters. Mandating the terminating 
action is based on our determination that, in this case, long term 
continued operational safety would be better ensured by a modification 
to remove the source of the problem, rather than by repetitive 
inspections. As a matter of policy, we have determined that long-term 
inspections might not provide the degree of safety necessary for the 
transport airplane fleet. This determination has led us to consider 
placing less emphasis on inspections and more emphasis on design 
improvements. The modification is consistent with these conditions. 
Therefore, we have not changed the second SNPRM in this regard.

Request To Justify Existing Repetitive Inspection Interval

    ACN stated that it would like the FAA to confirm that the new 
repetitive inspection interval proposed by Boeing is based on 
sufficient evidence and supported by proper risk analysis. ACN noted 
that the information should be specific to the Model 767 fleet and 
should justify such a drastic increase in the frequency of the 
repetitive inspection interval.
    We agree to provide justification. Operators have reported finding 
chafing of the fuel pump wire bundle before the accumulation of 30,000 
flight cycles or 60,000 flight hours. Wire bundle chafing could wear 
away the sleeving, jacket, and wire installation, in addition to 
exposing metal conductors and causing electrical arcing. Based on these 
reports, the design approval holder (DAH) recommended that the wiring 
inspection required by this proposed AD be done within 15,000 flight 
hours after doing the most recent inspection. The DAH also recommended 
not including flight cycles in the inspection interval. We analyzed 
their recommendations and agreed. The repetitive interval for the 
wiring inspection is within 15,000 flight hours after the most recent 
inspection until the terminating action has been done. We have not 
changed the second SNPRM in this regard.

Request To Correct Certain Paragraph Identifiers

    United Airlines (UAL), Japan Airlines (JAL), and UPS asked that the 
paragraph identifiers referenced within certain paragraphs in the first 
SNPRM (77 FR 39188, July 2, 2012) be corrected. UAL, JAL, and UPS 
stated that those paragraph identifiers are incorrect and suggested 
changes. The suggested changes to the first SNPRM are as follows:
     The reference within paragraph (i)(2)(i)(C) that 
identifies paragraph (h)(2)(i)(D) should identify paragraph 
(i)(2)(i)(D).
     The reference within paragraph (i)(2)(i)(D) that 
identifies paragraph (h)(2) should identify paragraph (i)(2).
     The reference within paragraph (k) that identifies 
paragraph (l)(1) or (l)(2) should identify paragraph (k)(1) or (k)(2).
    We agree with the commenters' requests for the reasons provided. We 
have changed those paragraphs identified above accordingly.

Request To Clarify Terminating Action

    JAL asked that paragraph (g) be added to paragraph (l) of the first 
SNPRM (77 FR 39188, July 2, 2012), so that accomplishing the 
terminating action specified in Boeing Alert Service Bulletin 767-
28A0104, Revision 1, dated March 2, 2012, applies to paragraphs (g) and 
(k) of the first SNPRM. JAL also asked that Boeing Alert Service 
Bulletin 767-28A0104, Revision 1, dated March 2, 2012, be added to 
paragraph (m) of the first SNPRM.
    We agree to clarify the terminating action. We have changed the 
last sentence of paragraph (l) of this second SNPRM to read: 
``Accomplishing the replacement specified in this paragraph ends the 
repetitive inspection requirements in paragraphs (g) and (k) of this 
AD.'' However, we have not changed paragraph (m) of this second SNPRM 
in this regard, because that paragraph gives credit for accomplishing 
the terminating action required by paragraph (l) of this second SNPRM, 
if the terminating action was done before the effective date of the AD 
using Boeing Alert Service Bulletin 767-28A0104, dated January 25, 
2011.

Request To Reference Certain AD Paragraph

    UAL stated that it reviewed Boeing Service Bulletin 767-28A0053, 
Revision 3, dated November 11, 2011, which contains a note that refers 
to paragraph (c)(2)(ii) of AD 2000-11-06, Amendment 39-11754 (65 FR 
34928, June 1, 2000; corrected August 1, 2000 (65 FR 46862)). UAL 
suggested that the first SNPRM (77 FR 39188, July 2, 2012), provide 
information regarding the applicable equivalent paragraph in the 
superseding AD.
    We acknowledge that Boeing Service Bulletin 767-28A0053, Revision 
3, dated November 11, 2011, refers to paragraph (c)(2)(ii) of AD 2000-
11-06, Amendment 39-11754 (65 FR 34928, June 1, 2000; corrected August 
1, 2000 (65 FR 46862)). Paragraph (c)(2)(ii) of AD 2000-11-06 
corresponds to paragraph (i)(2)(ii) of this second SNPRM. However, we 
do not agree with requiring a service information update, because the 
note which refers to paragraph (c)(2)(ii) of that service information 
will not adversely affect accomplishment of the required actions. We 
have not changed the second SNPRM in this regard.

Request To Clarify Certain Language in the ``Comments'' Section of the 
First SNPRM (77 FR 39188, July 2, 2012)

    Boeing asked that the language in the ``Comments'' section of the 
preamble of

[[Page 14936]]

the first SNPRM (77 FR 39188, July 2, 2012), which refers to Boeing 
Alert Service Bulletin 767-28A0104, Revision 1, dated March 2, 2012, 
including procedures for a wiring change, be clarified. Boeing stated 
that the language should emphasize that the procedures include the 
addition of a conduit liner and new wire bundle.
    We acknowledge and agree with the commenter's request for 
clarification; however, the content of that section of the preamble of 
the first SNPRM (77 FR 39188, July 2, 2012) does not reappear in this 
second SNPRM. However, we have added the words ``with a conduit liner'' 
to paragraph (l) of this second SNPRM for clarification.

Request To Clarify Service Information

    UAL requested that we reference new service information to address 
minor corrections for Boeing Alert Service Bulletin 767-28A0104, 
Revision 1, dated March 2, 2012. UAL noted that certain figure callouts 
should be revised.
    We do not agree. Boeing has not yet issued a revised service 
bulletin. Accomplishing Boeing Alert Service Bulletin 767-28A0104, 
Revision 1, dated March 2, 2012, addresses the identified unsafe 
condition. If a new service bulletin is issued later, operators may 
request an alternative method of compliance (AMOC) in accordance with 
the procedures specified in paragraph (p) of this AD. We have not 
changed the second SNPRM in this regard.

Request to Increase Work-Hours

    UAL asked that the work-hours specified in the ``Costs of 
Compliance'' section of the first SNPRM (77 FR 39188, July 2, 2012) be 
increased. UAL stated that the new proposed action in the first SNPRM 
specifies that it will take 33 work-hours per airplane; however, Boeing 
Alert Service Bulletin 767-28A0104, Revision 1, dated March 2, 2012, 
specifies 41.5 work-hours per airplane. UAL suggested increasing the 
work-hours to be consistent with the service information.
    We agree with the commenter. The cost data that was included in the 
first SNPRM (77 FR 39188, July 2, 2012) has been updated. We have 
changed the total number of work-hours for the ``new proposed action'' 
in the ``Costs of Compliance'' section of this second SNPRM 
accordingly.

FAA's Determination

    We are proposing this second supplemental NPRM 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. Certain changes described above expand the scope 
of the first SNPRM (77 FR 39188, July 2, 2012). As a result, we have 
determined that it is necessary to reopen the comment period to provide 
additional opportunity for the public to comment on this second SNPRM.

Proposed Requirements of the Second SNPRM

    This second SNPRM would require repetitive inspections to detect 
discrepancies of the wiring and surrounding Teflon sleeves of the fuel 
tank boost pumps and override/jettison pumps; replacement of the 
sleeves with new sleeves, for certain airplanes; and repair or 
replacement of the wiring and sleeves with new parts, as necessary; a 
terminating action for the repetitive inspections, to eliminate wire 
damage. This second SNPRM also would require revising the maintenance 
program to incorporate changes to the airworthiness limitations 
section.

Costs of Compliance

    We estimate that this proposed AD affects 414 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

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,

[[Page 14937]]

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.

List of Subjects in 14 CFR Part 39

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

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 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  [Amended]

0
2. The FAA amends Sec.  39.13 by removing airworthiness directive (AD) 
2000-11-06, Amendment 39-11754 (65 FR 34928, June 1, 2000; corrected 
August 1, 2000 (65 FR 46862)), and adding the following new AD:

The Boeing Company: Docket No. FAA-2010-1160; Directorate Identifier 
2010-NM-148-AD.

(a) Comments Due Date

    The FAA must receive comments on this AD action by April 22, 
2013.

(b) Affected ADs

    This AD supersedes AD 2000-11-06, Amendment 39-11754 (65 FR 
34928, June 1, 2000; corrected August 1, 2000 (65 FR 46862)).

(c) Applicability

    (1) This AD applies to The Boeing Company Model 767-200, -300, -
300F, and -400ER series airplanes, certificated in any category, as 
identified in Boeing Service Bulletin 767-28A0053, Revision 3, dated 
November 11, 2011.
    (2) This AD requires revisions to certain operator maintenance 
documents to include new actions (e.g., inspections) and/or Critical 
Design Configuration Control Limitations (CDCCLs). Compliance with 
these actions and/or CDCCLs is required by 14 CFR 91.403(c). For 
airplanes that have been previously modified, altered, or repaired 
in the areas addressed by this AD, the operator may not be able to 
accomplish the actions described in the revisions. In this 
situation, to comply with 14 CFR 91.403(c), the operator must 
request approval for an alternative method of compliance according 
to paragraph (p) of this AD. The request should include a 
description of changes to the required actions that will ensure the 
continued operational safety of the airplane.

(d) Subject

    Air Transport Association (ATA) of America Code 28: Fuel.

(e) Unsafe Condition

    This AD was prompted by fleet information indicating that the 
repetitive inspection interval in the existing AD is too long 
because excessive chafing of the sleeving continues to occur much 
earlier than expected between scheduled inspections. We are issuing 
this AD to detect and correct chafing of the fuel pump wire 
insulation and consequent exposure of the electrical conductor, 
which could result in electrical arcing between the wires and 
conduit and consequent fire or explosion of the fuel tank.

(f) Compliance

    You are responsible for having the actions required by this AD 
performed within the compliance times specified, unless the actions 
have already been done.

(g) Retained Repetitive Inspections

    This paragraph restates the requirements of paragraph (a) of AD 
2000-11-06, Amendment 39-11754 (65 FR 34928, June 1, 2000; corrected 
August 1, 2000 (65 FR 46862)), with revised service information. 
Perform a detailed visual inspection to detect discrepancies--
including the presence of cuts, splits, holes, worn areas, and 
lacing ties installed on the outside of the sleeves (except at the 
sleeve ends)--of the Teflon sleeves surrounding the wiring of the 
fuel tank boost pumps and override/jettison pumps, at the earlier of 
the times specified in paragraphs (g)(1) and (g)(2) of this AD, in 
accordance with Boeing Service Bulletin 767-28A0053, Revision 1, 
dated August 5, 1999; Boeing Alert Service Bulletin 767-28A0053, 
Revision 2, dated June 24, 2010; or Boeing Service Bulletin 767-
28A0053, Revision 3, dated November 11, 2011. Repeat the inspection 
thereafter at intervals not to exceed 60,000 flight hours or 30,000 
flight cycles, whichever occurs first. As of the effective date of 
this AD, only Boeing Service Bulletin 767-28A0053, Revision 3, dated 
November 11, 2011, may be used to do the actions required by this 
paragraph.
    (1) Prior to the accumulation of 50,000 total flight hours, or 
within 90 days after July 6, 2000 (the effective date of AD 2000-11-
06, Amendment 39-11754 (65 FR 34928, June 1, 2000; corrected August
