ACTION:
Final rule.
SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for certain
McDonnell Douglas Model DC–10–30
and DC–10–30F (KC–10A and KDC–10)
airplanes, Model DC–10–40 and DC–10–
40F airplanes, and Model MD–10–30F
airplanes. This AD requires installing
bracket assemblies and jumper wires in
the center main wheel well to improve
the bonding path between the structure
(wall) of the lower auxiliary fuel tank
and its internal fuel pumps; measuring
the electrical resistance between the fuel
pump housings and the fuel tank
structure; and doing corrective actions if
necessary. This AD results from fuel
system reviews conducted by the
manufacturer. We are issuing this AD to
detect and correct an inadequate bond
between the internal fuel pump
housings and the structure of the lower
auxiliary fuel tank. This condition, if
not corrected, could fail to meet fault
current requirements and result in a
potential ignition source that, in
combination with flammable fuel
vapors, could cause a fuel tank
explosion and consequent loss of the
airplane.
DATES: This AD becomes effective July
5, 2007.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in the AD
as of July 5, 2007.

Discussion
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would
apply to certain McDonnell Douglas
Model DC–10–30 and DC–10–30F (KC–
10A and KDC–10) airplanes, Model DC–
10–40 and DC–10–40F airplanes, and
Model MD–10–30F airplanes. That
NPRM was published in the Federal
Register on February 26, 2007 (72 FR
8305). That NPRM proposed to require
installing bracket assemblies and
jumper wires in the center main wheel
well to improve the bonding path
between the structure (wall) of the lower
auxiliary fuel tank and its internal fuel
pumps; measuring the electrical
resistance between the fuel pump
housings and the fuel tank structure;
and doing corrective actions if
necessary.
Comments
We provided the public the
opportunity to participate in the
development of this AD. We received no
comments on the NPRM or on the
determination of the cost to the public.
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 and determined that air
safety and the public interest require
adopting the AD with the change
described previously. We have
determined that this change will neither
increase the economic burden on any
operator nor increase the scope of the
AD.
Costs of Compliance
There are about 242 airplanes of the
affected design in the worldwide fleet.
This AD affects about 178 airplanes of
U.S. registry. The following table
provides the estimated costs for U.S.
operators to comply with this AD, at an
average labor rate of $80 per work hour.

Adoption of the Amendment
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.

Regulatory Findings

Authority for This Rulemaking

1
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.

to examine the regulatory evaluation.

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):
2007-11-15 McDonnell Douglas: Amendment 39-15072. Docket No. FAA-
2007-27340; Directorate Identifier 2006-NM-271-AD.
Effective Date
(a) This AD becomes effective July 5, 2007.
Affected ADs
(b) None.
Applicability
(c) This AD applies to McDonnell Douglas Model DC-10-30 and DC-
10-30F (KC-10A and KDC-10) airplanes, Model DC-10-40 and DC-10-40F
airplanes, and Model MD-10-30F airplanes; certificated in any
category; as identified in Boeing Service Bulletin DC10-28-245,
dated September 19, 2006.
Unsafe Condition
(d) This AD results from fuel system reviews conducted by the
manufacturer. We are issuing this AD to detect and correct an
inadequate bond between the internal fuel pump housings and the
structure of the lower auxiliary fuel tank. This condition, if not
corrected, could fail to meet fault current requirements and result
in a potential ignition source that, in combination with flammable
fuel vapors, could cause a fuel tank explosion and consequent loss
of the airplane.
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.
Installation of Brackets and Jumpers, and Resistance Measurement
(f) Within 60 months after the effective date of this AD, do the
actions described in paragraphs (f)(1) and (f)(2) of this AD, in
accordance with the Accomplishment Instructions of Boeing Service
Bulletin DC10-28-245, dated September 19, 2006.
(1) Install bracket assemblies and jumper wires between the
structure of the lower auxiliary fuel tank and its internal fuel
pumps.
(2) Do an electrical resistance measurement between the fuel
pump housings and the structure of the lower auxiliary fuel tank.
Corrective Action
(g) If any resistance measurement done in accordance with
paragraph (f)(2) of this AD is greater than 2.5 milliohms on either
fuel pump housing: Before further flight, rework the electrical
bonding between the fuel pump housings and the structure of the
lower auxiliary fuel tank as needed to achieve a resistance
measurement of 2.5 milliohms or less on both fuel pump housings, in
accordance with the Accomplishment Instructions of Boeing Service
Bulletin DC10-28-245, dated September 19, 2006.
Alternative Methods of Compliance (AMOCs)
(h)(1) The Manager, Los Angeles 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) To request a different method of compliance or a different
compliance time for this AD, follow the procedures in 14 CFR 39.19.
Before using any approved AMOC on any airplane to which the AMOC
applies, notify your appropriate principal inspector (PI) in the FAA
Flight Standards District Office (FSDO), or lacking a PI, your local
FSDO.
Material Incorporated by Reference
(i) You must use Boeing Service Bulletin DC10-28-245, dated

AD, unless the AD specifies otherwise. The Director of the Federal
Register approved the incorporation by reference of this document in
accordance with 5 U.S.C. 552(a) and 1 CFR part 51. Contact Boeing
