[Docket No. 95-CE-15-AD; Amendment 39-9184; AD 95-02-17]
Airworthiness Directives; Beech Aircraft Corporation Model 1900D
Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: This document publishes in the Federal Register an amendment
adopting Airworthiness Directive (AD) 95-02-17, which was sent
previously to known U.S. owners and operators of certain Beech Aircraft
Corporation Model 1900D airplanes. This AD requires inspecting (one-
time) the elevator trim tab control cables at the top of the vertical
stabilizer to ensure that cables (at the left, right, and crossover
pulleys) are correctly routed around the pulleys, within the cable
guide pins, and are not contacting any structure; and replacing any
cable that is incorrectly routed or chafed. The actions specified by
this AD are intended to prevent in-flight separation of the elevator
trim tab control cable caused by misrouting, which could result in loss
of control of the airplane.
DATES: Effective April 17, 1995, to all persons except those to whom it
was made immediately effective by priority letter AD 95-02-17, issued
January 25, 1995, which contained the requirements of this amendment.
Comments for inclusion in the Rules Docket must be received on or
before June 16, 1995.
ADDRESSES: Submit comments in triplicate to the Federal Aviation
Administration (FAA), Central Region, Office of the Assistant Chief
Counsel, Attention: Rules Docket 95-CE-15-AD, Room 1558, 601 E. 12th
Street, Kansas City, Missouri 64106.
Information that relates to this AD may be examined at the Rules
Docket at the address above.
FOR FURTHER INFORMATION CONTACT: Mr. Steven E. Potter, Wichita Aircraft
Certification Office, FAA, 1801 Airport Road, Mid-Continent Airport,
Wichita, Kansas 67209; telephone (316) 946-4124; facsimile (316) 946-
4407.
SUPPLEMENTARY INFORMATION: The FAA has received a report of an in-
flight separation of the elevator trim tab control (``nose up'' and
``nose down'') cable on a Beech Model 1900D airplane. The reported
cable separation prevented the airplane flight crew from using manual
and electrical nose up trim, and the flight crew experienced high
elevator ``nose down'' control forces. The flight crew was then able to
land the airplane without further incident.
Investigation of this incident showed that the elevator trim tab
control cable had separated in the vicinity of its guide pulley, which
is located at the top of the vertical stabilizer. The cable had been
routed outside the lower cable pulley guard pin instead of under the
guard pin. The routing configuration caused the cable to rub against
the stabilizer rib, resulting in cable separation.
Since an unsafe condition has been identified that is likely to
exist or develop in other Beech Model 1900D airplanes of the same type
design, the FAA issued priority letter AD 95-02-17 on January 25, 1995,
to prevent in-flight separation of the elevator trim tab control cable
caused by misrouting, which could result in loss of control of the
airplane. The AD requires inspecting (one-time) the elevator trim tab
control cables at the top of the vertical stabilizer to ensure that
cables (at the left, right, and crossover pulleys) are correctly routed
around the pulleys, within the cable guide pins, and are not contacting
any structure; and replacing any cable that is incorrectly routed or
chafed. Accomplishment of the required actions is in accordance with
the Beech 1900D Maintenance Manual, part number 129-590000-15A11,
Chapters 5-20-07, page 203; 6-40-00, page 3; 6-50-00, page 16; and 27-
30-04, pages 202 and 203.
Since it was found that immediate corrective action was required,
notice and opportunity for prior public comment thereon were
impracticable and contrary to the public interest, and good cause
existed to make AD 95-02-17 effective immediately by individual letters
issued on January 25, 1995, to known U.S. operators of certain Beech
Model 1900D airplanes. These conditions still exist, and the AD is
hereby 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 as to all persons.
Comments Invited
Although this action is in the form of a final rule that involves
requirements affecting immediate flight safety and, thus, was not
preceded by notice and opportunity to comment, comments are invited on
this rule. Interested persons are invited to comment on this rule by
submitting such written data, views, or arguments as they may desire.
Communications should identify the Rules Docket number and be submitted
in triplicate to the address specified above. All communications
received on or before the closing date for comments will be considered,
and this rule may be amended in light of the comments received. Factual
information that supports the commenter's ideas and suggestions is
extremely helpful in evaluating the effectiveness of the AD action and
determining whether additional rulemaking action would be needed.
Comments are specifically invited on the overall regulatory,
economic, environmental, and energy aspects of the rule that might
suggest a need to modify the rule. All comments submitted will be
available, both before and after the closing date for comments, in the
Rules Docket for examination by interested persons. A report that
summarizes each FAA-public contact concerned with the substance of this
AD will be filed in the Rules Docket.
Commenters wishing the FAA to acknowledge receipt of their comments
submitted in response to this notice must submit a self-addressed,
stamped postcard on which the following statement is made: ``Comments
to Docket No. 95-CE-15-AD.'' The postcard will be date stamped and
returned to the commenter.
The regulations adopted herein will not have substantial direct
effects 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. Therefore, in
accordance with Executive Order 12612, it is determined that this final
rule does not have sufficient federalism implications to warrant the
preparation of a Federalism Assessment.
The FAA has determined that this regulation is an emergency
regulation that must be issued immediately to correct an unsafe
condition in aircraft, and is not a ``significant regulatory action''
under Executive Order 12866. It has been determined further that this
action involves an emergency regulation under DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979). If it is determined
that this emergency regulation otherwise would be significant under DOT
Regulatory Policies and Procedures, a final regulatory evaluation will
be prepared [[Page 16367]] and placed in the Rules Docket. A copy of
it, if filed, may be obtained from the Rules Docket at the location
provided under the caption ADDRESSES.

Adoption of the Amendment
Accordingly, pursuant to the authority delegated to me by the
Administrator, the Federal Aviation Administration amends part 39 of
the Federal Aviation Regulations (14 CFR part 39) as follows:
PART 39--AIRWORTHINESS DIRECTIVES
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. App. 1354(a), 1421 and 1423; 49 U.S.C.
106(g); and 14 CFR 11.89.
Sec. 39.13 [Amended]
2. Section 39.13 is amended by adding a new airworthiness directive
to read as follows:
95-02-17 Beech Aircraft Corporation: Amendment 39-9184; Docket No.
95-CE-15-AD.
Applicability: Model 1900D airplanes, serial numbers UE-1
through UE-131, certificated in any category.
Note 1: This AD applies to each airplane identified in the
preceding applicability provision, regardless of whether it has been
modified, altered, or repaired in the area subject to the
requirements of this AD. For airplanes that have been modified,
altered, or repaired so that the performance of the requirements of
this AD is affected, the owner/operator must use the authority
provided in paragraph (c) of this AD to request approval from the
FAA. This approval may address either no action, if the current
configuration eliminates the unsafe condition, or different actions
necessary to address the unsafe condition described in this AD. Such
a request should include an assessment of the effect of the changed
configuration on the unsafe condition addressed by this AD. In no
case does the presence of any modification, alteration, or repair
remove any aircraft from the applicability of this AD.
Compliance: Required prior to further flight after the effective
date of this AD, unless already accomplished.
To prevent in-flight separation of the elevator trim tab control
cable, which could lead to loss of control of the airplane,
accomplish the following:
(a) In accordance with Beech 1900D Maintenance Manual, part
number 129-590000-15A11, Chapters 5-20-07, page 203; 6-40-00, page
3; 6-50-00, page 16; and 27-30-04, pages 202 and 203:
(1) Remove access panel Number 333ATC, which is located on the
top surface of the horizontal stabilizer, to gain access to the
elevator trim tab cable, guides, and pulleys;
(2) Inspect the cable routing to ensure that cables (at the
left, right, and crossover pulleys) are correctly routed around the
pulleys, within the cable guide pins, and are not contacting any
structure; and
(3) Replace any cable that is incorrectly routed (cable that
does not meet the criteria above in paragraph (a)(2) of this AD) or
is chafed.
Note 2: The procedures listed in Beech Communique 1900D-112,
dated January 1995, ``Inspection of Elevator Trim Tab Control
Cables'', are similar to those included in this priority letter AD.
Complying with all procedures in Beech Communique 1900D-112 is
considered equivalent to the requirements of paragraphs (a)(1),
(a)(2), and (a)(3) of this AD, and is considered ``unless already
accomplished'' for this portion of the AD.
Note 3: The compliance time specified in this AD takes
precedence over that specified in Beech Communique 1900D-112, dated
January 1995, ``Inspection of Elevator Trim Tab Control Cables''.
(b) Special flight permits may be issued in accordance with
sections 21.197 and 21.199 of the Federal Aviation Regulations (14
CFR 21.197 and 21.199) to operate the airplane to a location where
the requirements of this AD can be accomplished.
(c) An alternative method of compliance or adjustment of the
compliance time that provides an equivalent level of safety may be
approved by the Manager, Wichita Aircraft Certification Office
(ACO), FAA, 1801 Airport Road, Mid-Continent Airport, Wichita,
Kansas 67209. The request shall be forwarded through an appropriate
FAA Maintenance Inspector, who may add comments and then send it to
the Manager, Wichita ACO.
Note 4: Information concerning the existence of approved
alternative methods of compliance with this AD, if any, may be
obtained from the Wichita ACO.
(d) Information that relates to this AD may be examined at the
FAA, Central Region, Office of the Assistant Chief Counsel, Room
1558, 601 E. 12th Street, Kansas City, Missouri 64106.
(e) This amendment (39-9184) becomes effective on April 17,
1995, to all persons except those persons to whom it was made
immediately effective by priority letter AD 95-02-17, issued January
25, 1995, which contained the requirements of this amendment.
Issued in Kansas City, Missouri, on March 24, 1995.
