14 CFR Part 39
[Docket No. FAA-2005-20660; Directorate Identifier 2004-NM-242-AD;
Amendment 39-14166; AD 2005-13-29]
RIN 2120-AA64
Airworthiness Directives; Boeing Model 777-200 and -300 Series
Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Boeing Model 777-200 and -300 series airplanes. This AD
requires inspecting for the installation of the tie plate for the wire
bundles routed from lower section 41 into the center control stand in
the flight deck; inspecting for any wire chafing or damage and repair
if necessary; and installing a tie plate if necessary. This AD is
prompted by a report of missing tie plates for the wire bundles. We are
issuing this AD to prevent wire chafing, which could result in the loss
of flight control, communication, navigation, and engine fire control
systems. Loss of these systems could consequently result in a
significant reduction of safety margins, an increase in flight crew
workload, and in the case where loss of engine fire control is combined
with an engine fire, could result in an uncontrollable fire.
DATES: This AD becomes effective August 1, 2005.
The incorporation by reference of a certain publication listed in
the AD is approved by the Director of the Federal Register as of August
1, 2005.
ADDRESSES: For service information identified in this AD, contact
Boeing Commercial Airplanes, P.O. Box 3707, Seattle, Washington 98124-
2207.
Docket: The AD docket contains the proposed AD, comments, and any
final disposition. You can examine the AD docket on the Internet at
http://dms.dot.gov, or in person at the Docket Management Facility
office between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The Docket Management Facility office (telephone (800) 647-
5227) is located on the plaza level of the Nassif Building at the U.S.
Department of Transportation, 400 Seventh Street SW., room PL-401,
Washington, DC. This docket number is FAA-2005-20660; the directorate
identifier for this docket is 2004-NM-242-AD.
FOR FURTHER INFORMATION CONTACT: Georgios Roussos, Aerospace Engineer,
Systems and Equipment Branch, ANM-130S, FAA, Seattle Aircraft
Certification Office, 1601 Lind Avenue, SW., Renton, Washington 98055-
4056; telephone (425) 917-6482; fax (425) 917-6590.
SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39
with an AD for certain Boeing Model 777-200 and -300 series airplanes.
That action, published in the Federal Register on March 22, 2005 (70 FR
14430), proposed to require inspecting for the installation of the tie
plate for the wire bundles routed from lower section 41 into the center
control stand in the flight deck; inspecting for any wire chafing or
damage and repair if necessary; and installing a tie plate if
necessary.
Comment
We provided the public the opportunity to participate in the
development of this AD. We have considered the comment that has been
submitted on the proposed AD. The commenter supports the proposed AD.
Conclusion
We have carefully reviewed the available data, including the
comment that has been submitted, and determined that air safety and the
public interest require adopting the AD as proposed.
Costs of Compliance
There are about 289 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. 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.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive (AD):
2005-13-29 Boeing: Amendment 39-14166. Docket No. FAA-2005-20660;
Directorate Identifier 2004-NM-242-AD.
Effective Date
(a) This AD becomes effective August 1, 2005.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Boeing Model 777-200 and -300 series
airplanes, certificated in any category; as identified in Boeing
Alert Service Bulletin 777-27A0060, dated September 18, 2003.
Unsafe Condition
(d) This AD was prompted by a report of missing tie plates for
wire bundles that are routed from lower section 41 into the center
control stand in the flight deck. We are issuing this AD to prevent
wire chafing, which could result in the loss of flight control,
communication, navigation, and engine fire control systems. Loss of
these systems could consequently result in a significant reduction
of safety margins, an increase in flight crew workload, and in the
case where loss of engine fire control is combined with an engine
fire, could result in an uncontrollable fire.
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.
Inspection
(f) Within 18 months after the effective date of this AD,
inspect for installation of the tie plate for the wire bundles
routed from lower section 41 into the center control stand in the
flight deck, in accordance with the Accomplishment Instructions of
Boeing Alert Service Bulletin 777-27A0060, dated September 18, 2003.
(1) If the tie plate is found to be installed, no further action
is required by this AD.
(2) If the tie plate is missing, before further flight, do a
detailed inspection of the wire bundles for any chafing or damage
and repair if necessary, and install a tie plate in accordance with
the Accomplishment Instructions of the service bulletin.
Note 1: For the purposes of this AD, a detailed inspection is:
``An intensive examination of a specific item, installation, or
assembly to detect damage, failure, or irregularity. Available
lighting is normally supplemented with a direct source of good
lighting at an intensity deemed appropriate. Inspection aids such as
mirror, magnifying lenses, etc., may be necessary. Surface cleaning
and elaborate procedures may be required.''
Alternative Methods of Compliance (AMOCs)
(g) 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.
Material Incorporated by Reference
(h) You must use Boeing Alert Service Bulletin 777-27A0060,
dated September 18, 2003, to perform the actions that are required
by this AD, unless the AD specifies otherwise. The Director of the
Federal Register approves the incorporation by reference of this
document in accordance with 5 U.S.C. 552(a) and 1 CFR part 51. To
