Airworthiness Directives; McDonnell Douglas Corporation Model DC- 8-31, DC-8-32, DC-8-33, DC-8-41, DC-8-42, and DC-8-43 Airplanes; Model
DC-8-50 Series Airplanes; Model DC-8F-54 and DC-8F-55 Airplanes; Model
DC-8-60 Series Airplanes; Model DC-8-60F Series Airplanes; Model DC-8- 70 Series Airplanes; and Model DC-8-70F Series Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
SUMMARY: The FAA is superseding an existing airworthiness directive
(AD) that applies to all of the McDonnell Douglas Corporation airplanes identified above. The existing AD currently requires revising the maintenance program to incorporate new airworthiness limitations for fuel tank systems to satisfy Special Federal Aviation Regulation No. 88 requirements. This new AD adds requirements to revise the maintenance program to incorporate specific Critical Design Configuration Control
Limitations (CDCCL) information and install fuel tank float switch in- line fuses. This new AD also adds two Airworthiness Limitations inspections (ALIs). This AD results from a design review of the fuel tank systems. We are issuing this AD to prevent the potential for ignition sources inside fuel tanks caused by latent failures, alterations, repairs, or maintenance actions, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.
DATES: This AD becomes effective November 12, 2010.
The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of November 12, 2010.
On May 27, 2008 (73 FR 21523, April 22, 2008), the Director of the
Federal Register approved the incorporation by reference of a certain other publication listed in the AD.

SUPPLEMENTARY INFORMATION:
Discussion
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to include an AD that supersedes AD 2008-09-04, Amendment 39-15484 (73 FR 21523, April 22, 2008). The existing AD applies to all
Model DC-8-31, DC-8-32, DC-8-33, DC-8-41, DC-8-42, and DC-8-43 airplanes; Model DC-8-50 series airplanes; Model DC-8F-54 and DC-8F-55 airplanes; Model DC-8-60 series airplanes; Model DC-8-60F series airplanes; Model DC-8-70 series airplanes; and Model DC-8-70F series airplanes. That NPRM was published in the Federal Register on June 25, 2010 (75 FR 36298). That NPRM proposed to continue to require revising the maintenance program. That NPRM also proposed to add requirements to revise the maintenance program to incorporate specific Critical Design
Configuration Control Limitations (CDCCL) information and install fuel tank float switch in-line fuses. That NPRM also proposed to add two
Airworthiness Limitations inspections (ALIs).
Relevant Service Information
We reviewed Boeing DC-8 Special Compliance Item Report, MDC- 02K9030, Revision D, dated June 9, 2010. This service information does not add any additional work. We have revised paragraphs (j), (m), and
(n) of this AD to refer to this report.
Comments
We provided the public the opportunity to participate in the development of this AD. No comments have been received on the NPRM or on the determination of the cost to the public.
Change to Paragraph Reference
We revised paragraph (l) of this AD to correct a typographical error that appeared in the NPRM. In paragraph (l) of the NPRM, we inadvertently referred to ``paragraph (k)'' instead of ``paragraph
(j)'' of the AD. Paragraph (l) of this final rule correctly references paragraph (j) of this AD.
Explanation of Additional Change to NPRM
We also clarified the airplanes affected by paragraph (k) of this
AD by referring to the airplanes identified in Boeing Service Bulletin
DC8-28-090, dated October 9, 2009. Airplanes not listed in the effectivity of Boeing Service Bulletin DC8-28-090, dated October 9, 2009, are not required to do the installation required by paragraph (k) of this AD.
Conclusion
We have carefully reviewed the available data and determined that air safety and the public interest require adopting the AD with the changes mentioned previously.
Costs of Compliance
There are about 125 airplanes of the affected design in the worldwide fleet. The following table provides the estimated costs for
U.S. operators to comply with this 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, 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.

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.
Page 61991
Sec. 39.13 [Amended] 0 2. The Federal Aviation Administration (FAA) amends Sec. 39.13 by removing Amendment 39-15484 (73 FR 21523, April 22, 2008) and by adding the following new airworthiness directive (AD): 2010-21-03 McDonnell Douglas Corporation: Amendment 39-16463. Docket
No. FAA-2010-0639; Directorate Identifier 2009-NM-232-AD.
Effective Date
(a) This AD becomes effective November 12, 2010.
Affected ADs
(b) This AD supersedes AD 2008-09-04, Amendment 39-15484.
Applicability
(c) This AD applies to all McDonnell Douglas Model DC-8-31, DC- 8-32, DC-8-33, DC-8-41, DC-8-42, and DC-8-43 airplanes; Model DC-8- 51, DC-8-52, DC-8-53, and DC-8-55 airplanes; Model DC-8F-54 and DC- 8F-55 airplanes; Model DC-8-61, DC-8-62, and DC-8-63 airplanes;
Model DC-8-61F, DC-8-62F, and DC-8-63F airplanes; Model DC-8-71, DC- 8-72, and DC-8-73 airplanes; and Model DC-8-71F, DC-8-72F, and DC-8- 73F airplanes; certificated in any category.
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) in accordance with 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.
Subject
(d) Air Transport Association (ATA) of America Code 28: Fuel.
Unsafe Condition
(e) This AD results from a design review of the fuel tank systems. The Federal Aviation Administration is issuing this AD to prevent the potential for ignition sources inside fuel tanks caused by latent failures, alterations, repairs, or maintenance actions, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.
Compliance
(f) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the actions have already been done.

No Reporting Requirement
(h) Although the Boeing DC-8 Special Compliance Item Report,
MDC-02K9030, Revision A, dated August 8, 2006, specifies to submit certain information to the manufacturer, this AD does not require that action.
