SUPPLEMENTARY INFORMATION:
What events have caused this AD? On December 7, 2004, the left wing
of a Raytheon Beech Model A45 (T-34A), serial number G-13, separated
from the airplane in flight. The airplane, operated by Texas Air Aces,
crashed near Montgomery, Texas. The wing was found about a quarter mile
away from the crash site.
The left wing center section failed 4 inches inboard of the forward
wing attach fitting. In addition, FAA investigation revealed further
visual evidence of fatigue (found in other wing locations) not
previously addressed by AD 2001-13-18 R1, which FAA issued as a result
of an accident near Conroe, Texas.
A review of maintenance records shows that the accident airplane
was in compliance with AD 2001-13-18 R1.
AD 2001-13-18 R1 requires compliance with Raytheon Service Bulletin
SB57-3329 to inspect four locations per wing:
<bullet> Location (1)--9 fasteners at Wing Station (W.S.) 34
forward spar;
<bullet> Location (2)--the lower rear bathtub fitting;
<bullet> Location (3)--1 fastener at W.S. 64 forward spar; and
<bullet> Location (4)--2 fasteners at W.S. 66 rear spar.
The FAA approved four alternative methods of compliance (AMOCs) to
AD 2001-13-18 R1 based on front spar replacement or modification and
inspections of Location (2) and (4) of the rear spar.
On January 27, 2003, FAA issued emergency AD 2004-25-51 to require
you to perform an inspection and/or modification program approved
specifically for this AD by the FAA Wichita Aircraft Certification
Office (ACO).
Why is it important to publish this AD? The FAA found that
immediate corrective action was required, that notice and opportunity
for prior public comment were impracticable and contrary to the public
interest, and that good cause existed to make the AD effective
immediately by individual letters issued on December 10, 2004, to all
known U.S. operators of Raytheon Beech Models 45 (YT-34), A45 (T-34A,
B-45), and D45 (T-34B) airplanes. These conditions still exist, and the
AD is published in the Federal Register as an amendment to section
39.13 of the Federal Aviation Regulations (14 CFR 39.13) to make it
effective to all persons.
Comments Invited
Will I have the opportunity to comment before you issue the rule?
This AD is a final rule that involves requirements affecting flight
safety and was not preceded by notice and an opportunity for public
comment; however, we invite you to submit any written relevant data,
views, or arguments regarding this AD. Send your comments to an address
listed under ADDRESSES. Include ``Docket No. FAA-2004-19896;
Directorate Identifier 2004-CE-44-AD'' in the subject line of your
comments. If you want us to acknowledge receipt of your mailed
comments, send us a self-addressed, stamped postcard with the docket
number written on it; we will date-stamp your postcard and mail it back
to you. We specifically invite comments on the overall regulatory,
economic, environmental, and energy aspects of the rule that might
suggest a need to modify it. If a person contacts us through a
nonwritten communication, and that contact relates to a substantive
part of this AD, we will summarize the contact and place the summary in
the docket. We will consider all comments received by the closing date
and may amend the AD in light of those comments.
Authority For This Rulemaking
What authority does FAA have for issuing this rulemaking action?
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 AD.
Regulatory Findings
Will this AD impact various entities? 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.
Will this AD involve a significant rule or regulatory action? 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 the 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 summary of the costs to comply with this AD and
placed it in the AD Docket. You may get a copy of this summary by
sending a request to us at the address listed under ADDRESSES. Include
``Docket No. FAA-2004-19896; Directorate Identifier 2004-CE-44-AD'' in
your request.

directive (AD):
2004-25-51 Raytheon Aircraft Company: Amendment 39-13913; Docket No.
FAA-2004-19896; Directorate Identifier 2004-CE-44-AD.
When Does This AD Become Effective?
(a) This AD becomes effective on December 21, 2004, to all
