14 CFR Part 39
[Docket No. 2003-CE-43-AD; Amendment 39-13328; AD 2003-20-10]
RIN 2120-AA64
Airworthiness Directives; Raytheon Aircraft Company Beech Models
1900, 1900C, and 1900D Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) that
applies to all Raytheon Aircraft Company (Raytheon) Beech Models 1900,
1900C, and 1900D airplanes. This AD requires you to make a correction
to the elevator trim system maintenance procedures, incorporate a
temporary revision to the applicable maintenance manual, and
incorporate procedures that will enhance the existing elevator trim
operational check every time you have maintenance done on the elevator
trim system. This AD is the result of an analysis of the maintenance
procedures of the elevator trim system. We are issuing this AD to
detect and correct any maintenance-induced problems with the elevator
trim system installation before problems occur during operation. Such a
condition could lead to difficulties in controlling the airplane or a
total loss of pitch control.
DATES: This AD becomes effective on October 15, 2003.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the regulation as of
October 15, 2003.
We must receive any comments on this AD by December 7, 2003.
ADDRESSES: Use one of the following to submit comments on this AD:

SUPPLEMENTARY INFORMATION:
Discussion
What Events Have Caused This AD?
On August 26, 2003, a Raytheon Model Beech 1900D twin-turboprop
airplane was involved in an accident in the Nantucket Sound off
southeastern Massachusetts. The Raytheon Beech Model 1900D is designed
to carry 19 passengers. According to initial reports, the airplane took
off of Runway 24 at Barnstable Municipal Airport on Cape Cod. The pilot
immediately declared an emergency and, while en route to make an
emergency landing on Runway 33, crashed into the water.
While there is no determination of the cause of the accident and
the investigation is ongoing, FAA's review of the current maintenance
procedures of the elevator trim system reveals the following:
--The figures in the applicable maintenance manuals depict the elevator
trim cable drum at 180 degrees from the installed position and show the
open, keyed side of the drum instead of the flat side of the drum.
Following these figures when installing the control cables on the
forward control cable drum could reverse the action of the elevator
manual trim system; and
--The existing procedure can be enhanced by visually confirming the
trim wheel position and the trim tab position are consistent. Such a
check would detect and correct any problems with the elevator trim
system installation before problems occur during operation.
Although the figures (figure 9 for the 1900/1900C and figure 201
for the 1900D) in the existing maintenance manuals are incorrectly
depicted, following the step-by-step written instructions in the
existing procedure and referring to the orientation of the parts
removed would result in the correct installation and action of the
elevator trim system.
What Are the Consequences if the Condition Is Not Corrected?
An incorrectly installed elevator trim system component, if not
detected and corrected, could result in difficulties in controlling the
airplane or a total loss of pitch control.
Is There Service Information That Applies to This Subject?
Raytheon has issued Safety Communiqu[eacute] No. 234, dated
September 2003, to address this issue.
What Are the Provisions of This Service Information?
The safety communiqu[eacute] includes information about the
incorrect depictions of the figures in the applicable maintenance
manuals and also references the following temporary maintenance manual
revisions:
--Temporary Revision No. 27-5 to the Model 1900/1900C Airliner
Maintenance Manual: Revised ELEVATOR TRIM OPERATIONAL CHECK; and
--Temporary Revision No. 27-9 to the Model 1900D Airliner Maintenance
Manual: Added MANUAL ELEVATOR TRIM OPERATIONAL CHECK.
FAA's Determination and Requirements of the AD
What Has FAA Decided?
We have evaluated all pertinent information and identified an
unsafe condition that is likely to exist or develop on other products
of this same type design.
Since the unsafe condition described previously is likely to exist
or develop on other Raytheon Beech Models 1900, 1900C, and 1900D
airplanes of the same type design, this AD is being issued to detect
and correct any maintenance-induced problems with the elevator trim
system installation before problems occur during operation. Such a
condition could lead to difficulties in controlling the airplane or a
total loss of pitch control.
What Does This AD Require?
This AD requires you to:
--Make a correction to the elevator trim system maintenance procedures;
--Incorporate a temporary revision to the applicable maintenance
manual; and
--Incorporate procedures that will enhance the existing elevator trim
operational check every time you have maintenance done on the elevator
trim system.

How Does the Revision to 14 CFR Part 39 Affect This AD?
On July 10, 2002, we published a new version of 14 CFR part 39 (67
FR 47997, July 22, 2002), which governs FAA's AD system. This
regulation now includes material that relates to altered products,
special flight permits, and alternative methods of compliance. This
material previously was included in each individual AD. Since this
material is included in 14 CFR part 39, we will not include it in
future AD actions.
Comments Invited
Will I Have the Opportunity To Comment Prior to the Issuance of 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 ``AD Docket No. 2003-CE-43-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.
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
``AD Docket No. 2003-CE-43-AD'' in your request.
