ACTION: Final rule.
AGENCY:
We are superseding an
existing airworthiness directive (AD)
that applies to the products listed above.
This AD results from mandatory
continuing airworthiness information
(MCAI) originated by an aviation
authority of another country to identify
and correct an unsafe condition on an
aviation product. The MCAI describes
the unsafe condition as:
SUMMARY:
Two cases of main landing gear collapse
had been reported. Main landing gear
collapse may result in unsafe landing of the
aircraft.
*
*
*
*
*
We are issuing this AD to require
actions to correct the unsafe condition
on these products.
DATES: This AD becomes effective
October 18, 2011.
The Director of the Federal Register
approved the incorporation by reference
of certain publications listed in this AD
as of October 18, 2011.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would
apply to the specified products. That
NPRM was published in the Federal
Register on March 8, 2011 (76 FR
PO 00000
Frm 00014
Fmt 4700
Sfmt 4700
12629), and proposed to supersede AD
2007–22–09, Amendment 39–15245 (72
FR 61288, October 30, 2007). That
NPRM proposed to correct an unsafe
condition for the specified products.
The MCAI states:
Two cases of main landing gear collapse
had been reported. Main landing gear
collapse may result in unsafe landing of the
aircraft.
Revision 1 of this directive amended the
time compliance in paragraph C.2 (3 months
in addition to 500 hours air time), to add new
paragraph C.3 to cater for retract actuator
which has accumulated less than 4,000
landings or 2 years since new and to add new
paragraphs B.2 and C.4 to require that the
respective inspections be repetitively
performed until terminating action becomes
available.
Revision 2 of this directive amends the
detailed visual inspection requirement in
paragraph C.3 to include the main landing
gear retract actuator, part number 46550–11,
and to add new paragraph F to mandate the
incorporation of main landing gear retract
actuator part number, 46550–13 as the
terminating action and to add new paragraph
G for the maintenance requirement.
You may obtain further information by
examining the MCAI in the AD docket.
Comments
We gave the public the opportunity to
participate in developing this AD. We
received no comments on the NPRM (76
FR 12629, March 8, 2011) or on the
determination of the cost to the public.
Change Made to This AD
We have removed paragraph
(v)(3)(i)(D) of the NPRM (76 FR 12629,
March 8, 2011) from this AD, and
reidentified subsequent paragraphs
accordingly.
Conclusion
We reviewed the available data, and
determined that air safety and the
public interest require adopting the AD
with the change described previously.
We determined that this change will not
increase the economic burden on any
operator or increase the scope of the AD.
Differences Between This AD and the
MCAI or Service Information
We have reviewed the MCAI and
related service information and, in
general, agree with their substance. But
we might have found it necessary to use
different words from those in the MCAI
to ensure the AD is clear for U.S.
operators and is enforceable. In making
these changes, we do not intend to differ
substantively from the information
provided in the MCAI and related
service information.
We might also have required different
actions in this AD from those in the
MCAI in order to follow our FAA
E:\FR\FM\13SER1.SGM
13SER1
Federal Register / Vol. 76, No. 177 / Tuesday, September 13, 2011 / Rules and Regulations
policies. Any such differences are
highlighted in a Note within the AD.
Costs of Compliance
We estimate that this AD will affect
about 55 products of U.S. registry.
The actions that are required by AD
2007–22–09, Amendment 39–15245 (72
FR 61288, October 30, 2007), and
retained in this AD take about 5 workhours per product, at an average labor
rate of $85 per work-hour. Based on
these figures, the estimated cost of the
currently required actions is $425 per
product.
We estimate that it will take about 8
work-hours per product to comply with
the new basic requirements of this AD.
The average labor rate is $85 per workhour. Required parts will cost about
$27,511 per product. Where the service
information lists required parts costs
that are covered under warranty, we
have assumed that there will be no
charge for these parts. As we do not
control warranty coverage for affected
parties, some parties may incur costs
higher than estimated here. Based on
these figures, we estimate the cost of
this AD to the U.S. operators to be
$1,550,505, or $28,191 per product.
mstockstill on DSK4VPTVN1PROD with RULES
Authority for This Rulemaking
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
We 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.
For the reasons discussed above, I
certify this AD:
VerDate Mar<15>2010
15:54 Sep 12, 2011
Jkt 223001
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 regulatory evaluation
of the estimated costs to comply with
this AD and placed it in the AD docket.
Examining the AD Docket
You may examine the AD docket on
the Internet at https://
www.regulations.gov; or in person at the
Docket Operations office between 9 a.m.
and 5 p.m., Monday through Friday,

SUMMARY: We are superseding an existing airworthiness directive (AD)
that applies to the products listed above. This AD results from
mandatory continuing airworthiness information (MCAI) originated by an
aviation authority of another country to identify and correct an unsafe
condition on an aviation product. The MCAI describes the unsafe
condition as:
Two cases of main landing gear collapse had been reported. Main
landing gear collapse may result in unsafe landing of the aircraft.
* * * * *
We are issuing this AD to require actions to correct the unsafe
condition on these products.
DATES: This AD becomes effective October 18, 2011.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of October 18,
2011.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM was published in the Federal Register on March 8, 2011 (76 FR
12629), and proposed to supersede AD 2007-22-09, Amendment 39-15245 (72
FR 61288, October 30, 2007). That NPRM proposed to correct an unsafe
condition for the specified products. The MCAI states:
Two cases of main landing gear collapse had been reported. Main
landing gear collapse may result in unsafe landing of the aircraft.
Revision 1 of this directive amended the time compliance in
paragraph C.2 (3 months in addition to 500 hours air time), to add
new paragraph C.3 to cater for retract actuator which has
accumulated less than 4,000 landings or 2 years since new and to add
new paragraphs B.2 and C.4 to require that the respective
inspections be repetitively performed until terminating action
becomes available.
Revision 2 of this directive amends the detailed visual
inspection requirement in paragraph C.3 to include the main landing
gear retract actuator, part number 46550-11, and to add new
paragraph F to mandate the incorporation of main landing gear
retract actuator part number, 46550-13 as the terminating action and
to add new paragraph G for the maintenance requirement.
You may obtain further information by examining the MCAI in the AD
docket.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (76 FR 12629, March 8,
2011) or on the determination of the cost to the public.
Change Made to This AD
We have removed paragraph (v)(3)(i)(D) of the NPRM (76 FR 12629,
March 8, 2011) from this AD, and reidentified subsequent paragraphs
accordingly.
Conclusion
We reviewed the available data, and determined that air safety and
the public interest require adopting the AD with the change described
previously. We determined that this change will not increase the
economic burden on any operator or increase the scope of the AD.
Differences Between This AD and the MCAI or Service Information
We have reviewed the MCAI and related service information and, in
general, agree with their substance. But we might have found it
necessary to use different words from those in the MCAI to ensure the
AD is clear for U.S. operators and is enforceable. In making these
changes, we do not intend to differ substantively from the information
provided in the MCAI and related service information.
We might also have required different actions in this AD from those
in the MCAI in order to follow our FAA
[[Page 56291]]
policies. Any such differences are highlighted in a Note within the AD.
Costs of Compliance
We estimate that this AD will affect about 55 products of U.S.
registry.
The actions that are required by AD 2007-22-09, Amendment 39-15245
(72 FR 61288, October 30, 2007), and retained in this AD take about 5
work-hours per product, at an average labor rate of $85 per work-hour.
Based on these figures, the estimated cost of the currently required
actions is $425 per product.
We estimate that it will take about 8 work-hours per product to
comply with the new basic requirements of this AD. The average labor
rate is $85 per work-hour. Required parts will cost about $27,511 per
product. Where the service information lists required parts costs that
are covered under warranty, we have assumed that there will be no
charge for these parts. As we do not control warranty coverage for
affected parties, some parties may incur costs higher than estimated
here. Based on these figures, we estimate the cost of this AD to the
U.S. operators to be $1,550,505, or $28,191 per product.
Authority for This Rulemaking
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
We 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.
For the reasons discussed above, I certify 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 regulatory evaluation of the estimated costs to
comply with this AD and placed it in the AD docket.
Examining the AD Docket
You may examine the AD docket on the Internet at https://www.regulations.gov; or in person at the Docket Operations office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains the NPRM (76 FR 12629, March 8, 2011),
the regulatory evaluation, any comments received, and other
information. The street address for the Docket Operations office
(telephone (800) 647-5527) is in the ADDRESSES section. Comments will
be available in the AD docket shortly after receipt.

Restatement of Requirements of AD 2007-22-09, Amendment 39-15245 (72 FR
61288, October 30, 2007), With Updated Service Information, Limited
Affected Airplanes, and Revised Compliance Times
General Visual Inspection of Main Landing Gear (MLG) System, and
Corrective Actions
(g) For airplanes having S/Ns 003, 004, 006, and 008 through 182
inclusive (now referred to as S/Ns 4003, 4004, 4006, and 4008
through 4182 inclusive), before further flight, do a general visual
inspection to detect discrepancies of the left- and right-hand MLG
system and do all applicable corrective actions, in accordance with
a method approved by the Manager, New York Aircraft Certification
Office (ACO), FAA; or Transport Canada Civil Aviation (TCCA) (or its
delegated agent).
Note 1: For the purposes of this AD, a general visual inspection
is: ``A visual examination of an interior or exterior area,
installation, or assembly to detect obvious damage, failure, or
irregularity. This level of inspection is made from within touching
distance unless otherwise specified. A mirror may be necessary to
ensure visual access to all surfaces in the inspection area. This
level of inspection is made under normally available lighting
conditions such as daylight, hangar lighting, flashlight, or
droplight and may require removal or opening of access panels or
doors. Stands, ladders, or platforms may be required to gain
proximity to the area being checked.''
Note 2: Guidance on doing a general visual inspection to detect
discrepancies of the left- and right-hand MLG system can be found in
Tasks Z700-03E and Z700-04E of Part 1 (Maintenance Review Board
Report) of the Bombardier DHC-8 Series 400 Maintenance Requirements
Manual (PSM 1-84-7).
General Visual Inspection of the Jam Nut of the Retract Actuator of
the MLG and Corrective Actions
(h) For all airplanes except for the airplane having serial
number 4001: Before further flight, do a general visual inspection
of the jam nut of the retract actuator of the left- and right-hand
MLG to ensure the wire lock is in place and the nut is secured. If
the wire lock is not in place or if the jam nut is not
[[Page 56292]]
secured, before further flight, adjust the retracted length of the
rod end, torque the jam nut, install a wire lock, and lubricate the
piston, as applicable, in accordance with Bombardier Repair Drawing
(RD) 8/4-32-059, Issue 4, dated September 14, 2007; or Issue 7,
dated June 26, 2008. As of the effective date of this AD, use only
Bombardier RD 8/4-32-059, Issue 7, dated June 26, 2008. Doing the
revision required by paragraph (r) of this AD terminates the
