Airworthiness Directives; GROB–
WERKE Model G120A Airplanes
Federal Aviation
Administration (FAA), DOT.
ACTION: Final rule; request for
comments.
AGENCY:
SUMMARY: The FAA adopts a new
airworthiness directive (AD) for certain
GROB–WERKE Model G120A airplanes.
This AD requires you to replace the
main landing gear (MLG) up-lock hook
assembly. This AD results from
mandatory continuing airworthiness
information (MCAI) issued by the
airworthiness authority for Germany.
We are issuing this AD to prevent the
MLG from becoming jammed and not
extending, which could result in loss of
control of the airplane during landing.
During the comment period for the
notice of proposed rulemaking (NPRM)
regarding this action, we received a
comment recommending the
incorporation of service information to
install connecting bolts secured with
cotter pins instead of connecting bolts
secured with snap rings. All U.S.registered airplanes currently have these
actions incorporated so these actions do
not impose an additional burden over
that proposed in the NPRM and prior
public comment is not necessary.
However, we are reopening the
comment period to allow the public the
chance to comment on these additional
actions.
DATES: This AD becomes effective on
July 26, 2005.
As of July 26, 2005, the Director of the
Federal Register approved the
incorporation by reference of certain
publications listed in the regulation.

SUPPLEMENTARY INFORMATION:
Discussion
What events have caused this AD?
The Luftfahrt-Bundesamt (LBA), which
is the airworthiness authority for
Germany, recently notified FAA that an
unsafe condition may exist on certain
GROB–WERKE Model G120A airplanes.
The LBA reports that the up-lock/main
landing gear roller combination may
become jammed because of
contamination (i.e., dirt or dust) or
misalignment of the assembly.
What is the potential impact if FAA
took no action? This condition, if not
corrected, could cause the MLG to
become jammed and to not extend,
which could result in loss of control of
the airplane during landing.
Has FAA taken any action to this
point? We issued a proposal to amend
part 39 of the Federal Aviation
Regulations (14 CFR part 39) to include
an AD that would apply to certain
GROB–WERKE Model G120A airplanes.
This proposal was published in the
VerDate jul<14>2003
15:52 Jun 21, 2005
Jkt 205001
Federal Register as a notice of proposed
rulemaking (NPRM) on March 23, 2005
(70 FR 14599). The NPRM proposed the
requirement for you to replace the main
landing gear (MLG) up-lock hook
assembly.
Comments
Was the public invited to comment?
We provided the public the opportunity
to participate in developing this AD.
The following presents the comments
received on the proposal and FAA’s
response to each comment:
Comment Issue: Incorporate Additional
Actions Into the AD
What is the commenter’s concern?
The Director of Aircraft Maintenance of
the Airline Training Center Arizona,
Inc. ATCA requests that the provisions
of GROB–WERKE Service Bulletin MSB
1121–060, dated March 7, 2005, be
included in the FAA AD. MSB 1121–
060 incorporates a design change using
cotter pins in place of snap rings in the
landing gear assemblies. Snap ring
failure could cause landing gear up-lock
failure. MSB 1121–060 eliminates the
daily inspections of the landing gear.
The commenter represents the operator
of all 6 U.S.-registered airplanes.
What is FAA’s response to the
concern? The FAA agrees that
incorporation of MSB 1121–060 is a
reasonable action because of the
following reasons:
—Using snap rings in the landing gear
assemblies requires more rework than
using cotter pins in the landing gear
assemblies;
—Uncorporating the design change of
MSB 1121–060 eliminates daily
inspections;
—Additional provisions in the AD
would not increase the burden on
U.S. operators because ATCA has
already done the actions on their 6
airplanes, and they are the only
operator of the G120A in the United
States; and
—The additional actions will only affect
those airplanes imported to the
United States.
Conclusion
What is FAA’s final determination on
this issue? We have carefully reviewed
the available data and determined that
air safety and the public interest require
adopting the AD as proposed except for
the changes discussed above and minor
editorial corrections. We have
determined that these changes and
minor corrections:
—Are consistent with the intent that
was proposed in the NPRM for
correcting the unsafe condition; and
PO 00000
Frm 00010
Fmt 4700
Sfmt 4700
—Do not add any additional burden
upon the public than was already
proposed in the NPRM because all
U.S. registered airplanes already have
the additional actions incorporated.
Comments Invited
Will I have the opportunity to
comment before you issue the rule?
Since all 6 airplanes that are currently
on the U.S. register have the additional
actions incorporated, it has no adverse
economic impact and imposes no
additional burden on any person.
Therefore, prior notice and public
procedures are unnecessary.
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–
05–19473; Directorate Identifier 2004–
CE–35–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 datestamp 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.
Docket Information
Where can I go to view the docket
information? You may view the AD
docket that contains information
relating to this subject in person at the
DMS Docket Offices between 9 a.m. and
5 p.m. (eastern standard time), Monday
through Friday, except Federal holidays.
The Docket Office (telephone 1–800–
647–5227) is located on the plaza level
of the Department of Transportation
NASSIF Building at the street address
stated in ADDRESSES. You may also view
the AD docket on the Internet at
https://dms.dot.gov.
Changes to 14 CFR Part 39—Effect on
the AD
How does the revision to 14 CFR part
39 affect this AD? On July 10, 2002, the
FAA published a new version of 14 CFR
part 39 (67 FR 47997, July 22, 2002),
which governs the FAA’s AD system.
This regulation now includes material
that relates to altered products, special
flight permits, and alternative methods
E:\FR\FM\22JNR1.SGM
22JNR1
Federal Register / Vol. 70, No. 119 / Wednesday, June 22, 2005 / Rules and Regulations
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.
Costs of Compliance
How many airplanes does this AD
impact? We estimate that this AD affects
6 airplanes in the U.S. registry.
What is the cost impact of this AD on
owners/operators of the affected
airplanes? GROB–WERKE will provide
warranty credit for labor and parts.
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 other
information as included in the
Regulatory Evaluation) 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–05–19473;
Directorate Identifier 2004–CE–35–AD’’
in your request.

ACTION: Final rule.
AGENCY:
SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for all BAE
Systems (Operations) Limited
(Jetstream) Model 4101 airplanes. This
AD requires the overhaul of certain
auxiliary components installed on the
main landing gear (MLG) and nose
landing gear (NLG). This AD is
prompted by manufacturer
determination that overhaul limits need
to be imposed for certain auxiliary
components of the MLG and NLG.
Components that exceed the established
overhaul limits could fail due to fatigue,
wear, and age. We are issuing this AD
to prevent failure of the MLG or NLG,
and consequent damage to the airplane
and injury to flightcrew and passengers.
DATES: This AD becomes effective July
27, 2005.
The incorporation by reference of a
certain publication listed in the AD is
approved by the Director of the Federal
Register as of July 27, 2005.

Airworthiness Directives; GROB-WERKE Model G120A Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: The FAA adopts a new airworthiness directive (AD) for certain
GROB-WERKE Model G120A airplanes. This AD requires you to replace the
main landing gear (MLG) up-lock hook assembly. This AD results from
mandatory continuing airworthiness information (MCAI) issued by the
airworthiness authority for Germany. We are issuing this AD to prevent
the MLG from becoming jammed and not extending, which could result in
loss of control of the airplane during landing. During the comment
period for the notice of proposed rulemaking (NPRM) regarding this
action, we received a comment recommending the incorporation of service
information to install connecting bolts secured with cotter pins
instead of connecting bolts secured with snap rings. All U.S.-
registered airplanes currently have these actions incorporated so these
actions do not impose an additional burden over that proposed in the
NPRM and prior public comment is not necessary. However, we are
reopening the comment period to allow the public the chance to comment
on these additional actions.
DATES: This AD becomes effective on July 26, 2005.
As of July 26, 2005, the Director of the Federal Register approved
the incorporation by reference of certain publications listed in the
regulation.

SUPPLEMENTARY INFORMATION:
Discussion
What events have caused this AD? The Luftfahrt-Bundesamt (LBA),
which is the airworthiness authority for Germany, recently notified FAA
that an unsafe condition may exist on certain GROB-WERKE Model G120A
airplanes. The LBA reports that the up-lock/main landing gear roller
combination may become jammed because of contamination (i.e., dirt or
dust) or misalignment of the assembly.
What is the potential impact if FAA took no action? This condition,
if not corrected, could cause the MLG to become jammed and to not
extend, which could result in loss of control of the airplane during
landing.
Has FAA taken any action to this point? We issued a proposal to
amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to
include an AD that would apply to certain GROB-WERKE Model G120A
airplanes. This proposal was published in the Federal Register as a
notice of proposed rulemaking (NPRM) on March 23, 2005 (70 FR 14599).
The NPRM proposed the requirement for you to replace the main landing
gear (MLG) up-lock hook assembly.
Comments
Was the public invited to comment? We provided the public the
opportunity to participate in developing this AD. The following
presents the comments received on the proposal and FAA's response to
each comment:
Comment Issue: Incorporate Additional Actions Into the AD
What is the commenter's concern? The Director of Aircraft
Maintenance of the Airline Training Center Arizona, Inc. ATCA requests
that the provisions of GROB-WERKE Service Bulletin MSB 1121-060, dated
March 7, 2005, be included in the FAA AD. MSB 1121-060 incorporates a
design change using cotter pins in place of snap rings in the landing
gear assemblies. Snap ring failure could cause landing gear up-lock
failure. MSB 1121-060 eliminates the daily inspections of the landing
gear. The commenter represents the operator of all 6 U.S.-registered
airplanes.
What is FAA's response to the concern? The FAA agrees that
incorporation of MSB 1121-060 is a reasonable action because of the
following reasons:
--Using snap rings in the landing gear assemblies requires more rework
than using cotter pins in the landing gear assemblies;
--Uncorporating the design change of MSB 1121-060 eliminates daily
inspections;
--Additional provisions in the AD would not increase the burden on U.S.
operators because ATCA has already done the actions on their 6
airplanes, and they are the only operator of the G120A in the United
States; and
--The additional actions will only affect those airplanes imported to
the United States.
Conclusion
What is FAA's final determination on this issue? We have carefully
reviewed the available data and determined that air safety and the
public interest require adopting the AD as proposed except for the
changes discussed above and minor editorial corrections. We have
determined that these changes and minor corrections:
--Are consistent with the intent that was proposed in the NPRM for
correcting the unsafe condition; and
--Do not add any additional burden upon the public than was already
proposed in the NPRM because all U.S. registered airplanes already have
the additional actions incorporated.
Comments Invited
Will I have the opportunity to comment before you issue the rule?
Since all 6 airplanes that are currently on the U.S. register have the
additional actions incorporated, it has no adverse economic impact and
imposes no additional burden on any person. Therefore, prior notice and
public procedures are unnecessary.
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-05-19473; Directorate
Identifier 2004-CE-35-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.
Docket Information
Where can I go to view the docket information? You may view the AD
docket that contains information relating to this subject in person at
the DMS Docket Offices between 9 a.m. and 5 p.m. (eastern standard
time), Monday through Friday, except Federal holidays. The Docket
Office (telephone 1-800-647-5227) is located on the plaza level of the
Department of Transportation NASSIF Building at the street address
stated in ADDRESSES. You may also view the AD docket on the Internet at
https://dms.dot.gov.
Changes to 14 CFR Part 39--Effect on the AD
How does the revision to 14 CFR part 39 affect this AD? On July 10,
2002, the FAA published a new version of 14 CFR part 39 (67 FR 47997,
July 22, 2002), which governs the FAA's AD system. This regulation now
includes material that relates to altered products, special flight
permits, and alternative methods
[[Page 35995]]
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.
Costs of Compliance
How many airplanes does this AD impact? We estimate that this AD
affects 6 airplanes in the U.S. registry.
What is the cost impact of this AD on owners/operators of the
affected airplanes? GROB-WERKE will provide warranty credit for labor
and parts.
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
other information as included in the Regulatory Evaluation) 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-05-19473; Directorate Identifier 2004-CE-35-AD'' in your
request.
