SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for all
Boeing Model 707 airplanes, and all
Boeing Model 720 and 720B series
airplanes. This AD requires revising the
Limitations section of the airplane flight
manual (AFM). The AFM revisions
include instructions for monitoring the
low pressure lights for the center tank
fuel pumps, and a statement prohibiting
the resetting of a tripped circuit breaker
for a fuel pump in any tank. This AD
results from fuel system reviews
conducted by the manufacturer. We are
issuing this AD to prevent dry operation
of the fuel pumps in the center fuel
tank, which could result in high
temperatures or sparks inside the fuel
tank, ignition of fuel vapors, and
consequent fire or explosion. We are
also issuing this AD to prohibit the
resetting of a tripped circuit breaker for
a fuel pump in any tank, which could
allow an electrical fault to override the
protective features of the circuit breaker,
and result in sparks inside the fuel tank,
ignition of fuel vapors, and consequent
fire or explosion.
DATES: This AD becomes effective
November 1, 2005.

Examining the Docket
You may examine the airworthiness
directive (AD) docket on the Internet at

the plaza level of the Nassif Building at
the street address stated in the
ADDRESSES section.
Discussion
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would
apply to all Boeing Model 707 airplanes,
and all Boeing Model 720 and 720B
series airplanes. That NPRM was
published in the Federal Register on
April 1, 2005 (70 FR 16767). That NPRM
proposed to require revising the
Limitations section of the airplane flight
manual (AFM). The AFM revisions
include instructions for monitoring the
low pressure lights for the center tank
fuel pumps, and a statement prohibiting
the resetting of a tripped circuit breaker
for a fuel pump in any tank.
Comments
We provided the public the
opportunity to participate in the
development of this AD. We have
considered the comments received.
Support for the AD
One commenter supports the AD.
Request to Change Airplane Flight
Manual (AFM) Wording to be Similar to
Other AFMs
The commenter, the airplane
manufacturer, requests that we revise
the wording for the AFM revision that
is specified in paragraph (f) of the
NPRM. The commenter states that the
wording should be changed to agree
with the wording in an FAA-approved
AFM, and to be similar to the AFM
wording for other Boeing airplane
models.
We agree with the commenter. The
wording in the AFM revision should
agree with the previously approved
AFM and be similar to the AFM
wording for other Boeing airplane
models. These changes will reduce
confusion and provide the greatest
clarity for the AFM revision. We have
revised paragraph (f) of the final rule to
include the commenter’s requested
changes. However, operators that have
previously incorporated the information
in Approval Reference Number 045151
of the Boeing Model 707 AFM, dated
December 6, 2004, are not required to
change the AFM. That exclusion is
noted in revised wording in paragraph
(g) of the final rule that emphasizes
previous accomplishment of this
revision.
Request to Include Sentences for
Ground Operations and Flight
Operations in AFM Revision
The same commenter requests that we
revise the first paragraph of the AFM
revision specified in paragraph (f) of the
NPRM to include two sentences
regarding resetting the circuit breaker:
one for the flight case and one for the
ground case. The commenter states that
the proposed change in wording would
allow the circuit breaker to be reset
during ground operations after
maintenance has determined it is safe to
do so. The commenter states that the
proposed change is currently provided
in most flightcrew operations manuals
(FCOMs).
We do not agree with the commenter.
We met with the commenter on June 30,
2005, to discuss this comment and our
response to it. During the meeting we
discussed the fact that the AFM
provides limitations for flightcrews to
follow during flight operations. The
proposed change to the AFM would put
the flightcrew in the role of
maintenance by allowing the flightcrew
to reset a tripped circuit breaker during
ground operations. It is more
appropriate to incorporate ground
limitations (and warnings) in the
airplane maintenance manual (AMM)
rather than the AFM, to ensure that
these procedures are done by
maintenance personnel. We also
discussed that the procedures in the
FAA-approved AFM take priority over
the FCOM, which is not FAA-approved.
During the meeting, the commenter
stated that, if the proposed changes are
not made, it would revise the FCOM to
prohibit resetting the fuel pump circuit
breakers both in-flight and on the
ground. We are considering additional
rulemaking to revise the Airworthiness
Limitations section of the AMM to
ensure that maintenance does not reset
the circuit breaker until it is safe to do
so. We have not changed the final rule
in this regard.
Explanation of Change in Applicability
We have revised the applicability of
the AD to identify the model
designations as published in the most
recent type certificate data sheet for the
affected models.
Clarification of Alternative Method of
Compliance (AMOC) Paragraph
We have revised this action to clarify
the appropriate procedure for notifying
the principal inspector before using any
approved AMOC on any airplane to
which the AMOC applies.
Conclusion
We have carefully reviewed the
available data, including the comments
received, and determined that air safety
and the public interest require adopting
the AD with the changes described
previously. We have determined that
these changes will neither increase the
economic burden on any operator nor
increase the scope of the AD.
Costs of Compliance
There are about 225 airplanes of the
affected design in the worldwide fleet.

estimated costs for U.S. operators to
comply with this AD.

Federal Register / Vol. 70, No. 186 / Tuesday, September 27, 2005 / Rules and Regulations
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.
Regulatory Findings
We have determined that this AD will
not have federalism implications under
Executive Order 13132. This AD will
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 that this AD:
(1) Is not a ‘‘significant regulatory
action’’ under Executive Order 12866;
(2) Is not a ‘‘significant rule’’ under
DOT Regulatory Policies and Procedures
(44 FR 11034, February 26, 1979); and
(3) 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.
We prepared a regulatory evaluation
of the estimated costs to comply with
this AD and placed it in the AD docket.
See the ADDRESSES section for a location
to examine the regulatory evaluation.
Effective Date
(a) This AD becomes effective November 1,
2005.
Affected ADs
(b) None.
Applicability
(c) This AD applies to all Boeing Model
707–100 long body, –200, –100B long body,
and –100B short body series airplanes; Model
707–300, –300B, –300C, and –400 series
airplanes; and Model 720 and 720B series
airplanes; certificated in any category.
Unsafe Condition
(d) This AD results from fuel system
reviews conducted by the manufacturer. We
are issuing this AD to prevent dry operation
of the fuel pumps in the center fuel tank,
which could result in high temperatures or
sparks inside the fuel tank, ignition of fuel
vapors, and consequent fire or explosion. We
are also issuing this AD to prohibit the
resetting of a tripped circuit breaker for a fuel
pump in any tank, which could allow an
electrical fault to override the protective
features of the circuit breaker, and result in
sparks inside the fuel tank, ignition of fuel
vapors, and consequent fire or explosion.
(e) You are responsible for having the
actions required by this AD performed within
the compliance times specified, unless the
actions have already been done.
Airplane Flight Manual (AFM) Revisions
(f) Within 30 days after the effective date
of this AD: Revise the Limitations section of
the Boeing 707 AFM to include the following
information. This may be done by inserting
a copy of this AD into the AFM. Thereafter,
operate the airplane in accordance with the
limitations specified in these AFM revisions.
‘‘Fuel Pumps
For ground and flight operations, a fuel
pump circuit breaker which has tripped must
not be reset.

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.
[[Page 56351]]
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.
Regulatory Findings
We have determined that this AD will not have federalism
implications under Executive Order 13132. This AD will 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 that this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866;
(2) Is not a ``significant rule'' under DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979); and
(3) 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.
We prepared a regulatory evaluation of the estimated costs to
comply with this AD and placed it in the AD docket. See the ADDRESSES
section for a location to examine the regulatory evaluation.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Safety.
Adoption of the Amendment
0
Accordingly, under the authority delegated to me by the Administrator,
the FAA amends 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 Federal Aviation Administration (FAA) amends Sec. 39.13 by
adding the following new airworthiness directive (AD):
2005-20-02 Boeing: Amendment 39-14295. Docket No. FAA-2005-20785;
Directorate Identifier 2005-M-002-AD.
Effective Date
(a) This AD becomes effective November 1, 2005.
Affected ADs
(b) None.
Applicability
(c) This AD applies to all Boeing Model 707-100 long body, -200,
-100B long body, and -100B short body series airplanes; Model 707-
300, -300B, -300C, and -400 series airplanes; and Model 720 and 720B
series airplanes; certificated in any category.
Unsafe Condition
(d) This AD results from fuel system reviews conducted by the
manufacturer. We are issuing this AD to prevent dry operation of the
fuel pumps in the center fuel tank, which could result in high
temperatures or sparks inside the fuel tank, ignition of fuel
vapors, and consequent fire or explosion. We are also issuing this
AD to prohibit the resetting of a tripped circuit breaker for a fuel
pump in any tank, which could allow an electrical fault to override
the protective features of the circuit breaker, and result in sparks
inside the fuel tank, ignition of fuel vapors, and consequent fire
or explosion.
Compliance
(e) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Airplane Flight Manual (AFM) Revisions
(f) Within 30 days after the effective date of this AD: Revise
the Limitations section of the Boeing 707 AFM to include the
following information. This may be done by inserting a copy of this
AD into the AFM. Thereafter, operate the airplane in accordance with
the limitations specified in these AFM revisions.
``Fuel Pumps
For ground and flight operations, a fuel pump circuit breaker
which has tripped must not be reset.
Center Tank Fuel Pumps
Center tank fuel pumps must be `OFF' unless personnel are
available in the flight deck to monitor low pressure lights.
Each center tank fuel pump switch must be positioned to `OFF'
without delay when the respective center tank fuel pump low pressure
light illuminates.''
Note 1: When information identical to that in paragraph (f) of
this AD has been included in the general revision of the AFM, the
general revision may be inserted into the AFM, and the copy of this
AD may be removed from the AFM.
Actions Accomplished Previously
(g) Incorporation of the information in Approval Reference
Number 045151 of the Boeing Model 707 Airplane Flight Manual before
the effective date of this AD is considered acceptable for
compliance with the corresponding action specified in this AD.
Alternative Methods of Compliance (AMOCs)
(h)(1) The Manager, Seattle Aircraft Certification Office, FAA,
has the authority to approve AMOCs for this AD, if requested in
accordance with the procedures found in 14 CFR 39.19.
(2) Before using any AMOC approved in accordance with 14 CFR
39.19 on any airplane to which the AMOC applies, notify the
appropriate principal inspector in the FAA Flight Standards
Certificate Holding District Office.
(3) Before using any AMOC approved in accordance with Sec.
39.19 on any airplane to which the AMOC applies, notify the
appropriate principal inspector in the FAA Flight Standards
Certificate Holding District Office.
Material Incorporated by Reference
