Airworthiness Directives; The Boeing Company Model 767 Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of
comment period.
-----------------------------------------------------------------------
SUMMARY: We are revising an earlier proposed airworthiness directive
(AD) for the products listed above. That NPRM proposed to require
installing new panel assemblies in the main equipment center or on the
forward cargo compartment sidewall and removing certain relays from
some panels in the main equipment center. That NPRM also proposed to
require revising the maintenance program to incorporate Airworthiness
Limitations (AWLs) No. 28-AWL-27 and No. 28-AWL-28. That NPRM was
prompted by fuel system reviews conducted by the manufacturer. For
certain airplanes, this action revises that NPRM by proposing to
require prior or concurrent installation of a second fuel crossfeed
valve. This action also revises that NPRM by proposing an alternative
location for the installation of the new panel assemblies for airplanes
that have the optional water system drain plumbing and changing the
interconnecting wiring between the P141 panel and the P36 and P37
panels. For airplanes with a deactivated center fuel tank, this action
revises that NPRM by proposing an alternative functional test for the
left and right override/jettison pumps. We are proposing this
supplemental NPRM to prevent possible sources of ignition in a fuel
tank caused by electrical fault or uncommanded dry operation of the
main tank boost pumps and center auxiliary tank override and jettison
pumps. An ignition source in the fuel tank could result in a fire or an
explosion and consequent loss of the airplane. Since these actions
impose an additional burden over that proposed in the NPRM, 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 supplemental NPRM by May 2,
2011.

Discussion
We issued an NPRM to amend 14 CFR part 39 to include an
airworthiness directive (AD) that would apply to The Boeing Company
Model 767-200, -300, -300F, and -400ER series airplanes. That NPRM
published in the Federal Register on December 29, 2009 (74 FR 68743).
That NPRM proposed to require installing new panel assemblies in the
main equipment center or on the forward cargo compartment sidewall and
removing certain relays from some panels in the main equipment center.
That NPRM also proposed to require revising the maintenance program to
incorporate Airworthiness Limitations (AWLs) No. 28-AWL-27 and No. 28-
AWL-28.
Actions Since Original NPRM Was Issued
Since we issued the original NPRM, the manufacturer has notified us
that certain airplanes affected by the original NPRM have the optional
water system drain plumbing. This optional system was not addressed in
Boeing Alert Service Bulletin 767-28A0085, dated
[[Page 18665]]
January 10, 2008; or Boeing Service Bulletin 767-28A0085, Revision 1,
dated June 25, 2009; which we referred to as appropriate sources of
service information for accomplishing the proposed actions. Several
operators attempted to accomplish the actions and encountered equipment
installation interference. Specifically, the installation of the new
P141 panel at the location specified in either revision of the service
bulletin interferes with the optional water system drain plumbing.
We have revised the supplemental NPRM to refer to Boeing Service
Bulletin 767-28A0085, Revision 2, dated August 19, 2010.
Boeing Service Bulletin 767-28A0085, Revision 2, dated August 19,
2010, specifies the following changes:
For airplanes equipped with the optional water system
drain plumbing: An alternate location is specified for the installation
of the P141 panel. The interconnecting wiring between the P141 panel
and the P36 and P37 panels is also changed due to the relocation of the
P141 panel.
For airplanes with a deactivated center fuel tank
(alternately referred to as the center auxiliary fuel tank): An
alternative functional test is added for the left and right override/
jettison pumps.
For airplanes having line positions 1 through 430:
Installation of a second fuel crossfeed valve is added as a prior or
concurrent action. This installation is specified to be done in
accordance with Boeing Service Bulletin 767-28-0034, Revision 3, dated
March 14, 1996.
Additional error corrections and clarifications, including
clarifications of wiring configurations and routing, and increased
work-hours for airplanes with the optional water system drain plumbing.
Explanations of Additional Changes to the Original NPRM
We have added a new paragraph (d) to this supplemental NPRM to
provide the Air Transport Association (ATA) of America subject code 28,
Fuel. This code is added to make this supplemental NPRM parallel with
other new AD actions. We have reidentified subsequent paragraphs
accordingly.
We have included the cost of the prior/concurrent installation of
the second crossfeed valve.
We have also removed Table 1 and fully cited the service
information that was specified in the table. We reidentified the
subsequent table.
As noted above, we have added certain paragraphs to the
supplemental NPRM and, since we issued the original NPRM, the format
has been revised, and certain other paragraphs have been rearranged. As
a result, the corresponding paragraph identifiers have changed from the
original NPRM in this supplemental NPRM, as listed in the table titled
``Revised Paragraph Identifiers.'' In the disposition of comments we
will refer to the relevant paragraph of the original NPRM or the
supplemental NPRM, depending on context.

Comments
We gave the public the opportunity to comment on the original NPRM.
The following presents the comments received on the NPRM and the FAA's
response to each comment.
Request To Add Service Information to Table 1 of the Original NPRM
Japan Airlines (JAL) requested that we revise Table 1 in paragraph
(g) of the original NPRM to include the original versions of two
service bulletins as sources of service information. JAL pointed out
that these two service bulletins are referred to in AD 2009-16-06,
amendment 39-15989, which is the subject of paragraph (g) of the
original NPRM.
We agree with JAL's request. We have included a new Table 2 in this
supplemental NPRM to include Boeing Alert Service Bulletin 767-28A0083,
dated May 3, 2006; and Boeing Alert Service Bulletin 767-28A0084, dated
May 3, 2006. Both of these service bulletins are acceptable for
compliance with the requirements of AD 2009-16-06. Although Boeing
Service Bulletin 767-28A0083, dated May 3, 2006, is identified in
Paragraph 1.B., ``Concurrent Requirements,'' of Boeing Service Bulletin
767-28A0085, Revision 2, dated August 19, 2010, Boeing Alert Service
Bulletin 767-28A0084, dated May 3, 2006, is not listed in Paragraph
1.B. of Boeing Service Bulletin 767-28A0085, Revision 2, dated August
19, 2010. We have coordinated this difference with Boeing.
Requests To Refer to R1 of AD 2008-11-01
JAL, Continental Airlines (CAL), United Airlines (UAL), and UPS
pointed out that although paragraph (i) of the original NPRM proposed
the option of incorporating paragraph (g)(2) of AD 2008-11-01,
amendment 39-15523 (73 FR 29414, May 21, 2008), that AD has since been
revised to AD 2008-11-01 R1, amendment 39-16145 (74 FR 68515, December
28, 2009).
We agree with the requests to refer to AD 2008-11-01 R1, amendment
39-16145. We issued the revision to AD 2008-11-01 to clarify the AD's
intended effect on spares and on-airplane fuel tank system components,
regarding the use of maintenance manuals and instructions for continued
airworthiness. The actions required by AD 2008-11-01 R1 are consistent
with paragraph (j) of the original NPRM, which states that ``after
accomplishing the actions specified in paragraph (i) of this AD, no
alternative inspections or inspection intervals may be used.'' We have
changed paragraph (l) of this supplemental NPRM to refer to AD 2008-11-
01, amendment 39-15523, and AD 2008-11-01 R1, amendment 39-16145.
Requests for Clarification of Date of Maintenance Planning Data (MPD)
Document
Several commenters requested clarification of the intent of the
``Revision March 2009'' date of Boeing 767 Maintenance Planning Data
(MPD) Document, Section 9, D622T001-9, Revision March 2009, referred to
in the original NPRM.
JAL stated that the revision should be Revision April 2009
or Revision August 2009 because it does not appear that Revision March
2009 was issued.
CAL believed that the date should be Revision May 2009.
UAL asked if the intent of the proposed rule is to
override the requirements of AD 2008-11-01 R1 in that only Revision May
2009 may be used for compliance. UAL stated that it believed that
operators should be allowed to use either Revision April 2008 or
Revision May 2009, and that paragraph (h) of the original NPRM should
be revised accordingly.
UPS pointed out that as an optional action in AD 2008-11-
01 R1, AWLs No.
[[Page 18666]]
28-AWL-27 and No. 28-AWL-28 may be incorporated into the maintenance
program as identified in Revision April 2008 or Revision May 2009 of
the MPD. UPS was unclear as to whether the original NPRM would
supersede the previous option by requiring that only Revision March
2009 be used. UPS further stated that AD 2008-11-01 R1 notes that the
changes in Revision May 2009 are for clarification only and that either
Revision April 2008 or Revision May 2009 are acceptable for use.
We agree that the date of the MPD document needs to be clarified.
AWLs No. 28-AWL-27 and No. 28-AWL-28 were added to Boeing 767
Maintenance Planning Data (MPD) Document, Section 9, D622T001-9, in
Revision October 2007. None of the revisions of this MPD document since
that time have changed the text of AWLs No. 28-AWL-27 and No. 28-AWL-
28. Therefore, either of the revisions mentioned in AD 2008-11-01 R1,
Revision April 2008 or Revision May 2009, may be used to update the
maintenance program to incorporate AWLs No. 28-AWL-27 and No. 28-AWL-
28. We have revised paragraph (k) of this supplemental NPRM to specify
that Revision April 2008, Revision March 2009, or Revision May 2009,
may be used.
Request To Extend Compliance Time
CAL had no technical objection to the original NPRM, but pointed
out that although the compliance time for accomplishing the actions
proposed in the original NPRM is 60 months, the concurrent requirements
from AD 2009-16-06, which is specified as terminating action for
paragraph (g) of the original NPRM, have a compliance time of 36
months. CAL stated that doing the actions in AD 2009-16-06 requires
extensive airplane modifications and material allocations that can only
be accomplished during a heavy check or special maintenance hold.
Therefore, CAL requested that we consider a minor extension to the
compliance time in AD 2009-16-06.
We disagree with approving an extension to the compliance time for
AD 2009-16-06 through this supplemental NPRM. However, we will consider
requests for an adjustment to the compliance time under the provisions
of paragraph (o) of AD 2009-16-06 if data are submitted to substantiate
that such an adjustment would provide an acceptable level of safety. We
have not changed the supplemental NPRM in this regard.
Request To Remove Paragraph (g) of the Original NPRM
Boeing requested that we consider removing paragraph (g) from the
original NPRM. Paragraph (g) of the original NPRM is the concurrent
installation of an automatic shutoff system for the auxiliary fuel tank
pump. Boeing explained that the safety conditions and fixes associated
with references to Boeing Service Bulletin 767-28A0083, Revision 2,
dated February 12, 2009; or Boeing Service Bulletin 767-28A0084,
Revision 1, dated April 26, 2007; are already mandated by AD 2009-16-
06, and by the instructions in paragraph (f) of the original NPRM with
implementation of Boeing Service Bulletin 767-28A0085, Revision 2,
dated August 19, 2010. Boeing stated that future changes to paragraph
(g) of the original NPRM would require alternative methods of
compliance (AMOCs) and create added paperwork for Boeing, the airlines,
and the FAA.
We disagree with the request to remove paragraph (g) of the
original NPRM. Accomplishing the actions proposed in the original NPRM
for the center fuel tank pump system depend on the configuration of the
center fuel tank pump system of the affected airplanes as modified by
the accomplishment of the actions specified in the service information
identified in paragraph (g) of the original NPRM. Therefore, airplanes
in the effectivity of the service bulletins identified in Table 1 of
this supplemental NPRM must have the actions done prior to or
concurrently with the actions proposed in paragraph (g) of this
supplemental NPRM. If we remove paragraph (i) of this supplemental
NPRM, there is no assurance that the center fuel tank pump system for
the affected airplanes would be in the correct configuration during the
accomplishment of the actions proposed in paragraph (g) of this
supplemental NPRM.
Should the service information specified in paragraph (i) of this
supplemental NPRM change in a way that affects the ground fault
interrupt (GFI) relays and uncommanded-on protective feature, under the
provisions of paragraph (o) of this supplemental NPRM, we will consider
requests for approval of an AMOC if sufficient data are submitted to
substantiate that the design change would provide an acceptable level
of safety. We have not changed this supplemental NPRM in this regard.
Request To Remove Paragraphs (h), (i), and (j) of the Original NPRM
All Nippon Airways (ANA) requested that we remove the proposed
requirements of paragraphs (h), (i), and (j) of the original NPRM,
which specify incorporating AWLs No. 28-AWL-27 and No. 28-AWL-28 into
the maintenance program. ANA stated that these AWLs have already been
introduced in the airline maintenance program as required by AD 2008-
11-01 R1.
We disagree with the request to remove paragraphs (k), (l), and (m)
of the supplemental NPRM (paragraphs (h), (i), and (j) of the original
NPRM). Incorporating AWLs No. 28-AWL-27 and No. 28-AWL-28 into the
maintenance program in accordance with AD 2008-11-01 R1 is an option,
not a requirement. Operators may or may not decide to exercise this
option. The actions proposed in paragraph (k) of this supplemental NPRM
remain applicable. However, paragraph (l) of this supplemental NPRM
gives credit to operators of the affected airplanes that chose the
optional action; doing the optional action terminates the actions
proposed in paragraph (k) of this supplemental NPRM. We have not
changed this supplemental NPRM in this regard.
Request To Define Unsafe Condition and Corrective Actions Clearly
TDG Aerospace (TDG) requested that we revise the text of the
original NPRM to reflect the construction of a typical NPRM. TDG stated
that in that construction, the FAA typically discusses the unsafe
condition, describes the desired corrective action, and then refers to
the manufacturer's service information for approved instructions for
doing the corrective action. TDG pointed out that the intent of the
original NPRM is effectively masked by focusing on the ``Installation
of Panel Assemblies and Removal of Relays.'' TDG said this suggests
that the FAA intends to mandate ``Installation of Panel Assemblies and
Removal of Relays'' as a desired corrective action for the unsafe
condition identified in paragraph (d) of the original NPRM. TDG argued
that the corrective action is the installation of an uncommanded-on
protection system and installation of GFI relays. TDG stated that
installing new panels and removing relays is simply one method of
achieving the corrective action. TDG further stated that the language
of the rule is important with respect to the application for AMOCs and
said it would be more straightforward for
[[Page 18667]]
AMOC applicants to show an equivalent level of safety to installing
uncommanded-on protection and GFI relays as opposed to showing an
equivalent level of safety to installation of panel assemblies and
removal of relays.
We partially agree with TDG's request for clarification. We
disagree that the order of the supplemental NPRM should be revised. The
unsafe condition and the intent of the proposed rule are described in
the Summary and Discussion sections and paragraph (d) of the original
NPRM. The heading ``Installation of Panel Assemblies and Removal of
Relays'' is a descriptive title only and not the enforceable language
of paragraph (f) of the original NPRM. However, we agree that some
clarification of the P140 and P141 assemblies is necessary. These panel
assemblies are preassembled modules that contain the GFI relays and the
center fuel tank override/jettison pumps un-commanded ON protective
features. We have included in the Summary and Discussion sections of
the supplemental NPRM the words ``* * * main equipment center or on the
forward cargo compartment sidewall and removing certain relays from
some panels in the main equipment center.'' We have also revised the
wording in paragraph (g) of this supplemental NPRM to reflect a similar
wording.
Request for Clarification of Prior or Concurrent Actions for Airplanes
With Deactivated Center Fuel Tank
TDG pointed out that paragraph (j) of AD 2009-16-06 provides for
optional terminating action for paragraphs (f), (h), and (i) of that AD
via deactivation of the center fuel tank. TDG expressed concern that
operators that deactivate the center tank will not be able to do the
modifications proposed in the original NPRM without prior or concurrent
installation of the automatic shutoff system in accordance with the
actions in proposed paragraph (g) of the original NPRM. TDG stated that
requiring operators to install an automatic shutoff system on an
airplane with a deactivated center tank effectively eliminates the
center tank deactivation as an optional terminating action for AD 2009-
16-06.
We infer from TDG's comments that it sees a conflict between the
original NPRM and AD 2009-16-06, amendment 39-15989, that would
invalidate certain provisions of that AD. We disagree. We note that
paragraph (g) of the original NPRM proposed to require changes to all
affected airplanes, whether the airplanes have an active center fuel
tank (with changes made per paragraphs (f), (h), and (i) of AD 2009-16-
06), or a deactivated center fuel tank (as allowed by paragraph (j) of
AD 2009-16-06). Changes made per Boeing Service Bulletin 767-28A0085,
Revision 2, dated August 19, 2010, can be made on airplanes in either
configuration, and this service bulletin includes instructions for
testing of an airplane with a deactivated center fuel tank (reference
Step 3.B.29.e. of the Accomplishment Instructions of this service
bulletin). If a deactivated center fuel tank is later reactivated, the
requirements in paragraph (i) of AD 2009-16-06 must be done. We have
not changed the supplemental NPRM in this regard.
FAA's Determination
We are proposing this 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
original NPRM. 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 supplemental NPRM.
Proposed Requirements of the Supplemental NPRM
This supplemental NPRM would require accomplishing the actions
specified in the service information described previously.
Costs of Compliance
We estimate that this proposed AD will affect 416 airplanes of U.S.
registry.
We estimate the following costs to comply with this proposed AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost on U.S.
Action Labor cost Parts cost Cost per product operators

----------------------------------------------------------------------------------------------------------------
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.
[[Page 18668]]
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.

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
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]
2. The FAA amends Sec. 39.13 by adding the following new
airworthiness directive (AD):
The Boeing Company: Docket No. FAA-2009-1221; Directorate Identifier
2008-NM-097-AD.
Comments Due Date
(a) We must receive comments by May 2, 2011.
Affected ADs
(b) None.
Applicability
(c) 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 767-28A0085, Revision 2, dated
August 19, 2010.
Note 1: This AD requires revisions to certain operator
maintenance documents to include new inspections. Compliance with
these inspections is required by 14 CFR 91.403(c). For airplanes
that have been previously modified, altered, or repaired in the
areas addressed by these inspections, the operator may not be able
to accomplish the inspections 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 (AMOC)
according to paragraph (o) of this AD. The request should include a
description of changes to the required inspections that will ensure
the continued operational safety of the airplane.

(e) This AD results from fuel system reviews conducted by the
manufacturer. We are issuing this AD to prevent possible sources of
ignition in a fuel tank caused by electrical fault or uncommanded
dry operation of the main tank boost pumps and center auxiliary tank
override and jettison pumps. An ignition source in the fuel tank
could result in a fire or an explosion, and consequent loss of the
airplane.

(f) Comply with this AD within the compliance times specified,
unless already done.
Installation of Panel Assemblies and Removal of Relays
(g) Within 60 months after the effective date of this AD,
install ground fault interrupt relays (P140 and P141 panel
assemblies) and all applicable parts and components in the main
equipment center or in the forward cargo compartment sidewall, as

P33, P36, and P37 panels, in accordance with the Accomplishment
Instructions of Boeing Service Bulletin 767-28A0085, Revision 2,

(h) Although paragraph 3.B.29.e. of the Accomplishment
Instructions of Boeing Service Bulletin 767-28A0085, Revision 2,
dated August 19, 2010, specifies an alternative functional test of
the left and right center override pumps as an option, this AD
