AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding an existing airworthiness directive
(AD), which applies to certain McDonnell Douglas series airplanes. That
AD currently requires repetitive inspections of the electrical
connectors of the explosive cartridge wiring of the engine fire
extinguisher containers to verify if the identification number labels
are installed and legible; repetitive electrical tests of all explosive
cartridge wiring of the engine fire extinguisher containers to verify
proper installation and function; and corrective actions if necessary.
This new AD requires an inspection of the emergency shut off wire
assembly; installation of lanyards on the electrical connectors for the
engine fire extinguishing agent containers and for the auxiliary power
unit fire extinguishing agent containers if applicable; and related
investigative/corrective actions, as applicable. This AD is prompted by
reports of cross-wired electrical connectors of the engine fire
extinguishing agent containers. We are issuing this AD to detect and
correct cross-wired electrical connectors of the fire extinguishing
system, which could release fire extinguishing agent into the incorrect
engine nacelle in the event of an engine fire.
DATES: This AD becomes effective May 26, 2005.
The incorporation by reference of a certain publication listed in
the AD is approved by the Director of the Federal Register as of May
26, 2005.
On December 20, 2001 (66 FR 63157, December 5, 2001), the Director
of the Federal Register approved the incorporation by reference of a
certain other publication listed in the AD.

FOR FURTHER INFORMATION CONTACT: William S. Bond, Aerospace Engineer,
Propulsion Branch, ANM-140L, FAA, Los Angeles Aircraft Certification
Office, 3960 Paramount Boulevard, Lakewood, California 90712-4137;
telephone (562) 627-5253; fax (562) 627-5210.
SUPPLEMENTARY INFORMATION: The FAA proposed to amend part 39 of the
Federal Aviation Regulations (14 CFR part 39) with an AD to supersede
AD 2001-25-01, amendment 39-12553 (66 FR 63157, December 5, 2001). The
existing AD applies to certain McDonnell Douglas Model DC-8-33 and -43
airplanes; Model DC-8F-54 and DC-8F-55 airplanes; and Model DC-8-50, -
60, -60F, -70, and -70F series airplanes. The proposed AD was published
in the Federal Register on January 28, 2005 (70 FR 4055), to continue
to require repetitive inspections of the electrical connectors of the
explosive cartridge wiring of the engine fire extinguisher containers
to verify if the identification number labels are installed and
legible; repetitive electrical tests of all explosive cartridge wiring
of the engine fire extinguisher containers to verify proper
installation and function; and corrective actions if necessary. That
action also proposed to require an inspection of the emergency shut off
wire assembly; installation of lanyards on the electrical connectors
for the engine fire extinguishing agent containers and for the
auxiliary power unit (APU) fire extinguishing agent containers if
applicable; and related investigative/corrective actions, as
applicable.
Comments
We provided the public the opportunity to participate in the
development of this AD. No comments have been submitted on the proposed
AD or on the determination of the cost to the public.
Conclusion
We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD as proposed.
Costs of Compliance
There are about 233 airplanes of the affected design in the
worldwide fleet. The following table provides the estimated costs,
using an average labor rate of $65 per hour, 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. See the ADDRESSES section for a location to
examine the regulatory evaluation.
