14 CFR Part 39
[Docket No. FAA-2004-19943; Directorate Identifier 2004-NM-76-AD;
Amendment 39-14010; AD 2005-06-02]
RIN 2120-AA64
Airworthiness Directives; Boeing Model 757-200 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 757-200 series airplanes. This AD requires
modifying the wiring of the test ground signal for the master dim and
test system circuit in the flight compartment. This AD is prompted by a
report that the master dim and test system circuit does not have wiring
separation of the test ground signal for redundant equipment in the
flight compartment. We are issuing this AD to prevent a single fault
failure during flight, which could result in test patterns instead of
the selected radio frequencies showing on the communications panel.
These conditions could adversely affect voice and transponder
communication capability between the flightcrew and air traffic
control, which could result in increased pilot workload.
DATES: This AD becomes effective April 20, 2005.
The incorporation by reference of a certain publication listed in
the AD is approved by the Director of the Federal Register as of April
20, 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-2004-19943; the directorate
identifier for this docket is 2004-NM-76-AD.

and Equipment Branch, ANM-130S, FAA, Seattle Aircraft Certification
Office, 1601 Lind Avenue, SW., Renton, Washington 98055-4056; telephone

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39
with an AD for certain Boeing Model 757-200 series airplanes. That
action, published in the Federal Register on December 28, 2004 (69 FR
77675), proposed to require modifying the wiring of the test ground
signal for the master dim and test system circuit in the flight
compartment.
Comments
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.
Clarification of Applicability
In paragraph (c) of the proposed AD we inadvertently specified
``certain Boeing Model 757-200 series airplanes'' without identifying
the affected group. These airplanes are identified in Boeing Service
Bulletin 757-33-0050, Revision 2, dated December 4, 2003. We have
revised the final rule to clarify that applicability.
Editorial Change
The FAA noted that in paragraph (g) of the proposed AD, reference
was made to Boeing Service Bulletin 757-33-0050. We have revised that
reference to read Boeing Special Attention Service Bulletin 757-33-
0050.
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 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 55 airplanes of the affected design worldwide, and
30 airplanes of U.S. registry. The required modification (including the
operational test) will take between 2 and 3 work hours, depending on
the airplane configuration, at an average labor rate of $65 per work
hour. Required parts cost will be minimal. Based on these figures, the
estimated cost of the required modification for U.S. operators is
between $130 and $195 per airplane.
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
[[Page 12791]]
(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

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):
2005-06-02 Boeing: Amendment 39-14010. Docket No. FAA-2004-19943;
Directorate Identifier 2004-NM-76-AD.
Effective Date
(a) This AD becomes effective April 20, 2005.
Affected ADs
(b) None.
Applicability

certificated in any category; as identified in Boeing Service
Bulletin 757-33-0050, Revision 2, dated December 4, 2003.
Unsafe Condition
(d) This AD was prompted by a report that the master dim and
test system circuit does not have wiring separation of the test
ground signal for redundant equipment in the flight compartment. We
are issuing this AD to prevent a single fault failure during flight
which could result in test patterns instead of the selected radio
frequencies showing on the communications panel. These conditions
could adversely affect voice and transponder communication
capability between the flightcrew and air traffic control, which
could result in increased pilot workload.

AD performed within the compliance times specified, unless the
actions have already been done.
Modification
(f) Within 60 months after the effective date of this AD: Modify

system circuit in the flight compartment by doing all the applicable
actions specified in Boeing Service Bulletin 757-33-0050, Revision
2, dated December 4, 2003.
Modifications Done Using Previous Issues of the Service Bulletin
(g) Modifications done before the effective date of this AD in
accordance with Boeing Special Attention Service Bulletin 757-33-
0050, dated August 15, 2002; or Revision 1, dated January 30, 2003;
are considered acceptable for compliance with paragraph (f) of this
AD.
Alternative Methods of Compliance (AMOCs)
(h) 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
(i) You must use Boeing Service Bulletin 757-33-0050, Revision
2, dated December 4, 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. For
