ACTION: Final rule. AGENCY: The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 737–300, –400, –500, –600, –700, –700C, –800, and –900 series airplanes. This AD requires modifying the wiring for the master dim and test system. For certain airplanes, this AD also requires related concurrent actions as necessary. This AD results from 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 in flight from simulating a test condition and showing test patterns instead of the selected radio frequencies on the communications panels, which could inhibit communication between the flightcrew and the control tower, SUMMARY: affecting the continued safe flight of the airplane. DATES: This AD becomes effective September 5, 2006. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of September 5, 2006.

That supplemental NPRM was published in the Federal Register on May 26, 2006 (71 FR 30346). That supplemental NPRM proposed to require modifying the wiring for the master dim and test system. For certain airplanes, the supplemental NPRM also proposed to require related concurrent actions as necessary. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the single comment received. The commenter, Boeing, supports the supplemental NPRM. Conclusion We have carefully reviewed the available data, including the comment received, and determined that air safety and the public interest require adopting the AD as proposed in the supplemental NPRM. Costs of Compliance There are about 2,868 airplanes of the affected design in the worldwide fleet. This AD will affect about 1,181 airplanes of U.S. registry.

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 737-300, -400, -500, -600, -700, -700C, -800, and
-900 series airplanes. This AD requires modifying the wiring for the
master dim and test system. For certain airplanes, this AD also
requires related concurrent actions as necessary. This AD results from
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 in flight from simulating a test condition and showing
test patterns instead of the selected radio frequencies on the
communications panels, which could inhibit communication between the
flightcrew and the control tower, affecting the continued safe flight
of the airplane.

DATES: This AD becomes effective September 5, 2006.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of September 5,
2006.

SUPPLEMENTARY INFORMATION:

Examining the Docket

You may examine the AD docket on the Internet at https://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 street address stated in the
ADDRESSES section.

Discussion

The FAA issued a supplemental notice of proposed rulemaking (NPRM)
to amend 14 CFR part 39 to include an AD that would apply to certain
Boeing Model 737-300, -400, -500, -600, -700, -700C, -800, and -900
series airplanes. That supplemental NPRM was published in the Federal
Register on May 26, 2006 (71 FR 30346). That supplemental NPRM proposed
to require modifying the wiring for the master dim and test system. For
certain airplanes, the supplemental NPRM also proposed to require
related concurrent actions as necessary.

Comments

We provided the public the opportunity to participate in the
development of this AD. We have considered the single comment received.
The commenter, Boeing, supports the supplemental NPRM.

Conclusion

We have carefully reviewed the available data, including the
comment received, and determined that air safety and the public
interest require adopting the AD as proposed in the supplemental NPRM.

Costs of Compliance

There are about 2,868 airplanes of the affected design in the
worldwide fleet. This AD will affect about 1,181 airplanes of U.S.
registry. 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.

Sec. 39.13 [Amended]

0
2. The Federal Aviation Administration (FAA) amends Sec. 39.13 by
adding the following new airworthiness directive (AD):

2006-15-18 Boeing: Amendment 39-14699. FAA-2004-19245; Directorate
Identifier 2004-NM-108-AD.

Effective Date

(a) This AD becomes effective September 5, 2006.

Affected ADs

(b) None.

Applicability

(c) This AD applies to Boeing Model 737-300, -400, and -500
series airplanes identified in Boeing Special Attention Service
Bulletin 737-33-1132, Revision 2, dated September 8, 2005; and Model
737-600, -700, -700C, -800, and -900 series airplanes identified in
Boeing Service Bulletin 737-33-1133, Revision 3, dated September 8,
2005; certificated in any category.

Unsafe Condition

(d) This AD results from 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 in flight from
simulating a test condition and showing test patterns instead of the
selected radio frequencies on the communications panels, which could
inhibit communication between the flightcrew and the control tower,
affecting the continued safe flight 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.

Modification

(f) Within 48 months after the effective date of this AD: Modify
the wiring for the master dim test system in accordance with the
Accomplishment Instructions of Boeing Special Attention Service
Bulletin 737-33-1132, Revision 2, dated September 8, 2005 (for Model
737-300, -400, and -500 series airplanes); and Boeing Service
Bulletin 737-33-1133, Revision 3, dated September 8, 2005 (for Model
737-600, -700, -700C, -800, and -900 series airplanes); as
applicable.

Actions Required To Be Accomplished Prior to or Concurrently With
