AGENCY:
SUMMARY: The FAA proposes to adopt a
new airworthiness directive (AD) for
General Machine—Diecron, Inc. (GMD)
actuator nut assembly, part number
(P/N) GMD115–810029–17 and P/N
GMD115–810029–23, that are installed
on certain airplanes. This proposed AD
would require you to determine by
maintenance records check and/or
inspection whether any actuator nut
assembly, P/N GMD115–810029–17 or
P/N GMD115–810029–23, is installed
on the right main landing gear (MLG)
actuator, and, if installed, would require
you to replace it with a new actuator nut
assembly, P/N GMD115–810029–23B or
FAA-approved equivalent P/N. This
proposed AD results from several
reports of failures of the actuator nut
assembly, P/N GMD115–810029–17 and
P/N GMD115–810029–23. We are
issuing this proposed AD to prevent
failure of the actuator nut assembly for
the right MLG actuator, which could
result in failure of the MLG. This failure
could prevent the extension or
retraction of the MLG.
DATES: We must receive comments on
this proposed AD by April 3, 2006.

Discussion
What events have caused this proposed
AD?
The FAA has received several reports
of failure of the actuator nut assembly,
part numbers (P/N) GMD115–810029–
17 and P/N GMD115–810029–23, for the
right main landing gear (MLG) actuator
in airplanes not equipped with a
hydraulic MLG or modified to a
hydraulic MLG. One failure resulted in
the MLG not extending and a ‘‘gear-up’’
landing.
Investigation found the separation of
the threaded nut insert in the P/N
GMD115–810029–17 and P/N GMD115–
810029–23 MLG actuator nut assembly.
The insert has internal and external
threads. The external threads of the
insert screw into a threaded steel tube
to complete the actuator nut assembly.
The internal threads of the insert
interface with the Actuator Screw in the
Raytheon MLG Actuator. Rotation of the
MLG Actuator Screw in the right MLG
Actuator transmits load to the insert
which tends to unscrew the insert from
the GMD Actuator Nut Assembly during
the extension cycle of the MLG. If the
insert separates (unscrews) from the
threaded steel tube, it can prevent the

actuator from extending or retracting the
MLG to the locked position. The
separation of the insert only occurs in
the right MLG actuator.
with a new P/N GMD115–810029–23B
actuator nut assembly.
What is the potential impact if FAA took
no action?
Why have we determined AD action is
necessary and what would this
proposed AD require?
We are proposing this AD to address
an unsafe condition that we determined
is likely to exist or develop on other
products of this same type design. The
proposed AD would require you to
determine by maintenance records
check and/or inspection whether any
actuator nut assembly, P/N GMD115–
810029–17 or P/N GMD115–810029–23,
is installed on the right MLG actuator,
and, if installed, would require you to
replace it with a new actuator nut
assembly, P/N GMD115–810029–23B or
FAA-approved equivalent P/N. The
proposed AD would require you to use
the service information described
previously to perform these actions.
This condition, if not corrected, could
prevent the extension or retraction of
the MLG.
Relevant Service Information
Is there service information that applies
to this subject?
We have reviewed General Machine
Diecron, Inc. Service Bulletin GM–D
32–30–01/102505, dated November 21,
2005.
What are the provisions of this service
information?
The service information describes
procedures for:
• Determining by maintenance
records check and/or inspection
whether any actuator nut assembly,
P/N GMD115–810029–17 or P/N
GMD115–810029–23, is installed on the
right MLG actuator; and
• If any actuator nut assembly, P/N
GMD115–810029–17 or P/N GMD115–
810029–23, is installed, replacing it
FAA’s Determination and Requirements
of the Proposed AD
Differences Between the Proposed AD
and Service Information
810029–23, is installed on the right
MLG actuator, this AD would require
you to replace it with a new actuator nut
assembly, P/N GMD115–810029–23B or
FAA-equivalent P/N. The requirements
of the proposed AD, if adopted as a final
rule, would take precedence over the
provisions in the service information.
Costs of Compliance
How many airplanes would this
proposed AD impact?
We estimate that this proposed AD
affects 1,629 airplanes in the U.S.
registry.
What would be the cost impact of this
proposed AD on owners/operators of the
affected airplanes?
We estimate the following costs to do
this proposed maintenance records
check and/or inspection to determine
whether any actuator nut assembly,
P/N GMD115–810029–17 or P/N
GMD115–810029–23, is installed on the
right MLG actuator:

Authority for This Rulemaking
cprice-sewell on PROD1PC71 with PROPOSALS
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 rulemaking
action.
Regulatory Findings
Would this proposed AD impact various
entities?
We have determined that this
proposed AD would not have federalism
implications under Executive Order
13132. This proposed AD would 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 the proposed regulation:
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.

Extension of Comment Period
Chemical Safety and Hazard
Investigation Board.
ACTION: Proposed rule; extension of
comment period.
AGENCY:
SUMMARY: The Chemical Safety and
Hazard Investigation Board (CSB) is
extending the period for comment on
the proposed rule entitled, ‘‘Accident
Investigation Initiation Notice and
Order to Preserve Evidence,’’ which was
published in the Federal Register on
January 4, 2006 (71 FR 309).
DATES: Written comments now must be
received on or before March 6, 2006.
ADDRESSES: You may submit written
comments concerning the proposed
rule, by the following method:
• Mail / Express delivery service:
Chemical Safety and Hazard
Investigation Board, Office of General
Counsel, Attn: Christopher Warner,
2175 K Street, NW., Suite 650,
Washington, DC 20037.
FOR FURTHER INFORMATION CONTACT:
Christopher Warner, 202–261–7600.
SUPPLEMENTARY INFORMATION: On
January 4, 2006, the CSB published in
the Federal Register (71 FR 309) a
proposed rule that would establish the
means by which the CSB will preserve
accident scenes/sites, and the evidence
within those sites. The proposed rule is
centered around a procedure by which
the CSB may issue a written ‘‘Notice of
Accident Investigation Initiation and
Order to Preserve Evidence.’’ The CSB
is proposing this rule to address critical
PO 00000
Frm 00004
Fmt 4702
Sfmt 4702
issues surrounding evidence
preservation, so that CSB investigators
have the fullest possible opportunity to
determine the causes of chemical
accidents to which they are deployed.
The proposed rule provided for a 30-day
comment period, to end on February 3,
2006.
After publication of the proposed
rule, the CSB received requests for a 60day extension of the comment period
from three trade associations—the
American Petroleum Institute, The
Fertilizer Institute, and the Synthetic
Organic Chemical Manufacturers
Association. Another private sector
firm, ORC Worldwide, requested a 30day extension. The reasons cited in
support of additional time for comments
included a need to more thoroughly
evaluate the proposed rule, a need to
obtain and review relevant background
materials, and a need for member
companies to review and discuss the
proposed rule. The CSB also received a
request for a 60-day comment period
extension from one government agency,
the U.S. Occupational Safety and Health
Administration, which cited the
complexity of the issues presented by
the proposed rule.
The CSB carefully reviewed these
requests and considered the reasons for
a comment period extension cited
therein. The CSB also considered the
importance of maintaining a timely
rulemaking process, in light of the direct
impact the proposed rule would have on
the agency’s core mission investigative
activities. The CSB has thus determined
that a 30-day extension of the comment
period is reasonable and sufficient.
Written comments on the proposed rule
must now be received by March 6, 2006.

Airworthiness Directives; General Machine--Diecron, Inc. Actuator
Nut Assembly for the Right Main Landing Gear
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for General Machine--Diecron, Inc. (GMD) actuator nut assembly, part
number (P/N) GMD115-810029-17 and P/N GMD115-810029-23, that are
installed on certain airplanes. This proposed AD would require you to
determine by maintenance records check and/or inspection whether any
actuator nut assembly, P/N GMD115-810029-17 or P/N GMD115-810029-23, is
installed on the right main landing gear (MLG) actuator, and, if
installed, would require you to replace it with a new actuator nut
assembly, P/N GMD115-810029-23B or FAA-approved equivalent P/N. This
proposed AD results from several reports of failures of the actuator
nut assembly, P/N GMD115-810029-17 and P/N GMD115-810029-23. We are
issuing this proposed AD to prevent failure of the actuator nut
assembly for the right MLG actuator, which could result in failure of
the MLG. This failure could prevent the extension or retraction of the
MLG.

Discussion
What events have caused this proposed AD?
The FAA has received several reports of failure of the actuator nut
assembly, part numbers (P/N) GMD115-810029-17 and P/N GMD115-810029-23,
for the right main landing gear (MLG) actuator in airplanes not
equipped with a hydraulic MLG or modified to a hydraulic MLG. One
failure resulted in the MLG not extending and a ``gear-up'' landing.
Investigation found the separation of the threaded nut insert in
the P/N GMD115-810029-17 and P/N GMD115-810029-23 MLG actuator nut
assembly. The insert has internal and external threads. The external
threads of the insert screw into a threaded steel tube to complete the
actuator nut assembly. The internal threads of the insert interface
with the Actuator Screw in the Raytheon MLG Actuator. Rotation of the
MLG Actuator Screw in the right MLG Actuator transmits load to the
insert which tends to unscrew the insert from the GMD Actuator Nut
Assembly during the extension cycle of the MLG. If the insert separates
(unscrews) from the threaded steel tube, it can prevent the
[[Page 5797]]
actuator from extending or retracting the MLG to the locked position.
The separation of the insert only occurs in the right MLG actuator.
What is the potential impact if FAA took no action?
This condition, if not corrected, could prevent the extension or
retraction of the MLG.
Relevant Service Information
Is there service information that applies to this subject?
We have reviewed General Machine Diecron, Inc. Service Bulletin GM-
D 32-30-01/102505, dated November 21, 2005.
What are the provisions of this service information?
The service information describes procedures for:
Determining by maintenance records check and/or inspection
whether any actuator nut assembly, P/N GMD115-810029-17 or P/N GMD115-
810029-23, is installed on the right MLG actuator; and
If any actuator nut assembly, P/N GMD115-810029-17 or P/N
GMD115-810029-23, is installed, replacing it with a new P/N GMD115-
810029-23B actuator nut assembly.
FAA's Determination and Requirements of the Proposed AD
Why have we determined AD action is necessary and what would this
proposed AD require?
We are proposing this AD to address an unsafe condition that we
determined is likely to exist or develop on other products of this same
type design. The proposed AD would require you to determine by
maintenance records check and/or inspection whether any actuator nut
assembly, P/N GMD115-810029-17 or P/N GMD115-810029-23, is installed on
the right MLG actuator, and, if installed, would require you to replace
it with a new actuator nut assembly, P/N GMD115-810029-23B or FAA-
approved equivalent P/N. The proposed AD would require you to use the
service information described previously to perform these actions.
Differences Between the Proposed AD and Service Information
Are there differences between the requirements of this AD and what is
contained in the service information?
If any actuator nut assembly, P/N GMD115-810029-17 or P/N GMD115-
810029-23, is installed on the right MLG actuator, this AD would
require you to replace it with a new actuator nut assembly, P/N GMD115-
810029-23B or FAA-equivalent P/N. The requirements of the proposed AD,
if adopted as a final rule, would take precedence over the provisions
in the service information.
Costs of Compliance
How many airplanes would this proposed AD impact?
We estimate that this proposed AD affects 1,629 airplanes in the
U.S. registry.
What would be the cost impact of this proposed AD on owners/operators
of the affected airplanes?
We estimate the following costs to do this proposed maintenance
records check and/or inspection to determine whether any actuator nut
assembly, P/N GMD115-810029-17 or P/N GMD115-810029-23, is installed on
the right MLG actuator:
----------------------------------------------------------------------------------------------------------------
Total cost Per Total cost on U.S.
Labor cost Parts cost airplane operators
----------------------------------------------------------------------------------------------------------------
1 work hour x $65 = $65................. Not Applicable............ $65 1,629 x $65 = $105,885
----------------------------------------------------------------------------------------------------------------
We estimate the following costs to do any necessary replacements of
the actuator nut assembly that would be required based on the results
of this proposed inspection. We have no way of determining the number
of airplanes that may need this replacement:
------------------------------------------------------------------------
Total cost
Labor cost Parts cost per airplane
------------------------------------------------------------------------
4 work hours x $65 = $260................... $1,700 $1,960
------------------------------------------------------------------------
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
rulemaking action.
Regulatory Findings
Would this proposed AD impact various entities?
We have determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 the proposed
regulation:
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.
[[Page 5798]]
We prepared a regulatory evaluation of the estimated costs to
comply with this proposed AD. See the ADDRESSES section for a location
to examine the regulatory evaluation.
