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 16, 2011 (76 FR
14349). That NPRM proposed to correct
an unsafe condition for the specified
products. The MCAI states:
wwoods2 on DSK1DXX6B1PROD with RULES_PART 1
As a result of fatigue-testing programme on
Jetstream aeroplanes, cracks have been found
on the main landing gear (MLG) fittings that
embody modifications JM5218 or JM8003.
This condition, if not detected and
corrected, could lead to a MLG collapse on
the ground or during landing, possibly
resulting in a fuel tank rupture, consequent
damage to the aeroplane or injury to the
occupants.
We are issuing this AD to require
actions to correct the unsafe condition
on these products.
DATES: This AD becomes effective June
22, 2011.
On June 22, 2011, the Director of the
Federal Register approved the
incorporation by reference of a certain
publication listed in this AD.
ADDRESSES: You may examine the AD
docket on the Internet at https://
www.regulations.gov or in person at
Document Management Facility, U.S.

order to ensure the safe operation of the MLG
beyond the accumulation of 41,000 Flight
Cycles (FC).
For the reasons described above, this AD
requires initial and repetitive eddy current
inspections, and depending on findings,
accomplishment of corrective actions.
The MCAI requires replacing or
repairing any cracked MLG fitting found
during the initial and repetitive
inspections. You may obtain further

Comments
We gave the public the opportunity to
participate in developing this AD. We
PO 00000
Frm 00011
Fmt 4700
Sfmt 4700

received no comments on the NPRM or
on the determination of the cost to the
public.
Conclusion
We reviewed the available data and
determined that air safety and the
public interest require adopting the AD
as proposed.
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 FAA policies.
Any such differences are highlighted in
a Note within the AD.
Costs of Compliance
We estimate that this AD will affect
190 products of U.S. registry. We also
estimate that it will take about 20 workhours per product to comply with the
basic requirements of this AD. The
average labor rate is $85 per work-hour.
Based on these figures, we estimate
the cost of this AD on U.S. operators to
be $323,000 or $1,700 per product.
In addition, we estimate that any
necessary follow-on actions will take
about 4 work-hours and require parts
costing $8,000, for a cost of $8,340 per
product. We have no way of
determining the number of products
that may need these actions.
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

Federal Register / Vol. 76, No. 96 / Wednesday, May 18, 2011 / Rules and Regulations
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
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 Management Facility between 9
a.m. and 5 p.m., Monday through
Friday, except Federal holidays. The AD
docket contains the NPRM, the
regulatory evaluation, any comments
received, and other information. The

(b) None.
Applicability
(c) This AD applies to British Aerospace
Regional Aircraft Model HP.137 Jetstream
Mk.1, Jetstream Series 200, Jetstream Series
3101, and Jetstream Model 3201 airplanes, all
serial numbers, that are:
(1) Equipped with main landing gear
(MLG) fittings, part number (P/N)
1379133B1/B2/B3/B4 that incorporate
Modifications JM5218 or JM8003; and
(2) Certificated in any category.
Subject
(d) Air Transport Association of America
(ATA) Code 32: Landing Gear.
Reason
(e) The mandatory continuing
airworthiness information (MCAI) states:
As a result of fatigue-testing programme on
Jetstream aeroplanes, cracks have been found
on the main landing gear (MLG) fittings that
embody modifications JM5218 or JM8003.
This condition, if not detected and
corrected, could lead to a MLG collapse on
the ground or during landing, possibly
resulting in a fuel tank rupture, consequent
damage to the aeroplane or injury to the
occupants.
Analysis of this failure indicates that an
inspection regime has to be implemented in
order to ensure the safe operation of the MLG
beyond the accumulation of 41 000 Flight
Cycles (FC).
For the reasons described above, this AD
requires initial and repetitive eddy current
inspections, and depending on findings,
accomplishment of corrective actions.
The MCAI requires replacing or repairing any
cracked MLG fitting found during the initial
and repetitive inspections. You may obtain
further information by examining the MCAI
in the AD docket.

inspection required in paragraph (f)(1),
(f)(2)(i), or (f)(2)(ii) of this AD, repetitively
thereafter upon accumulating 27,000 flight
cycles (landings) after the last inspection,
eddy current inspect all the MLG leg pivot
beam fastener bores for cracks.
(4) As of June 22, 2011 (the effective date
of this AD), only install a MLG fitting
specified in paragraph (c)(1) of this AD that
has been eddy current inspected and found
free of cracks following British Aerospace
Jetstream Series 3100 & 3200 Service Bulletin
32–JA090240, Revision 1, dated January 18,
2010.
(5) Some of the compliance times of this
AD are presented in flight cycles (landings).
If the total flight cycles have not been kept,
multiply the total number of airplane hours
time-in-service by 0.75. For the purposes of
this AD:
(i) 75 cycles equals 100 hours TIS; and
(ii) 750 cycles equals 1,000 hours TIS.
Note 1: Credit will be given for the
inspection required in paragraph (f)(1) of this
AD and the corrective action required in
paragraph (f)(2) of this AD if already done
before June 22, 2011 (the effective date of this

ACTION: Final rule.
AGENCY:
We are adopting a new
airworthiness directive (AD) for the
specified Eurocopter France (ECF)
helicopters. This AD results from a
mandatory continuing airworthiness
information (MCAI) AD issued by the
aviation authority of the European
Aviation Safety Agency (EASA), which
is the Technical Agent for the Member
States of the European Community. The
superseding MCAI AD states that
several engine flameouts have involved
failure of the 41-tooth pinion in the
engine accessory gearbox. Each affected
helicopter had a starter-generator
manufactured by one company.
Investigation revealed the torque
damping system of the starter-generator
was inoperative due to incorrect
adjustment that caused bending stresses
on the 41-tooth pinion. Failure of the
pinion causes the engine fuel pump to
stop operating, resulting in an engine
flameout. The EASA AD requires a new
adjustment procedure to optimize the
performance of the specified startergenerator damping assembly. This AD is
intended to prevent failure of a pinion
and a fuel pump, engine flameout, and
subsequent loss of control of the
helicopter.

SUMMARY: We are adopting a new airworthiness directive (AD) for the
products listed above. This AD results from mandatory continuing
airworthiness information (MCAI) issued 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:
As a result of fatigue-testing programme on Jetstream
aeroplanes, cracks have been found on the main landing gear (MLG)
fittings that embody modifications JM5218 or JM8003.
This condition, if not detected and corrected, could lead to a
MLG collapse on the ground or during landing, possibly resulting in
a fuel tank rupture, consequent damage to the aeroplane or injury to
the occupants.
We are issuing this AD to require actions to correct the unsafe
condition on these products.

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 16, 2011 (76
FR 14349). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
As a result of fatigue-testing programme on Jetstream
aeroplanes, cracks have been found on the main landing gear (MLG)
fittings that embody modifications JM5218 or JM8003.
This condition, if not detected and corrected, could lead to a
MLG collapse on the ground or during landing, possibly resulting in
a fuel tank rupture, consequent damage to the aeroplane or injury to
the occupants.
Analysis of this failure indicates that an inspection regime has
to be implemented in order to ensure the safe operation of the MLG
beyond the accumulation of 41,000 Flight Cycles (FC).
For the reasons described above, this AD requires initial and
repetitive eddy current inspections, and depending on findings,
accomplishment of corrective actions.
The MCAI requires replacing or repairing any cracked MLG fitting found
during the initial and repetitive inspections. 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 or on the determination of
the cost to the public.
Conclusion
We reviewed the available data and determined that air safety and
the public interest require adopting the AD as proposed.
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 FAA policies. Any such differences are
highlighted in a Note within the AD.
Costs of Compliance
We estimate that this AD will affect 190 products of U.S. registry.
We also estimate that it will take about 20 work-hours per product to
comply with the basic requirements of this AD. The average labor rate
is $85 per work-hour.
Based on these figures, we estimate the cost of this AD on U.S.
operators to be $323,000 or $1,700 per product.
In addition, we estimate that any necessary follow-on actions will
take about 4 work-hours and require parts costing $8,000, for a cost of
$8,340 per product. We have no way of determining the number of
products that may need these actions.
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
[[Page 28636]]
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 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 Management Facility
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains the NPRM, the regulatory evaluation,
any comments received, and other information. The street address for
the Docket Office (telephone (800) 647-5527) is in the ADDRESSES
section. Comments will be available in the AD docket shortly after
receipt.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
Adoption of the Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new AD:
2011-11-01 British Aerospace Regional Aircraft: Amendment 39-16699;
Docket No. FAA-2011-0230; Directorate Identifier 2011-CE-004-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective June 22,
2011.
Affected ADs
(b) None.
Applicability
(c) This AD applies to British Aerospace Regional Aircraft Model
HP.137 Jetstream Mk.1, Jetstream Series 200, Jetstream Series 3101,
and Jetstream Model 3201 airplanes, all serial numbers, that are:
(1) Equipped with main landing gear (MLG) fittings, part number
(P/N) 1379133B1/B2/B3/B4 that incorporate Modifications JM5218 or
JM8003; and
(2) Certificated in any category.
Subject
(d) Air Transport Association of America (ATA) Code 32: Landing
Gear.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
As a result of fatigue-testing programme on Jetstream
aeroplanes, cracks have been found on the main landing gear (MLG)
fittings that embody modifications JM5218 or JM8003.
This condition, if not detected and corrected, could lead to a
MLG collapse on the ground or during landing, possibly resulting in
a fuel tank rupture, consequent damage to the aeroplane or injury to
the occupants.
Analysis of this failure indicates that an inspection regime has
to be implemented in order to ensure the safe operation of the MLG
beyond the accumulation of 41 000 Flight Cycles (FC).
For the reasons described above, this AD requires initial and
repetitive eddy current inspections, and depending on findings,
accomplishment of corrective actions.
The MCAI requires replacing or repairing any cracked MLG fitting
found during the initial and repetitive inspections. You may obtain
further information by examining the MCAI in the AD docket.
Actions and Compliance
(f) Unless already done, do the following actions:
(1) Upon accumulating 41,000 flight cycles (landings) on the MLG
since first installation or within the next 2,000 flight cycles
(landings) on the MLG after June 22, 2011 (the effective date of
this AD), whichever occurs later, eddy current inspect all the MLG
leg pivot beam fastener bores for cracks. Do the inspections
following British Aerospace Jetstream Series 3100 & 3200 Service
Bulletin 32-JA090240, Revision 1, dated January 18, 2010.
(2) Before further flight after any inspection required in
paragraphs (f)(1), (f)(2)(i), (f)(2)(ii), and (f)(3) of this AD in
which cracks are found, replace the MLG fitting or repair any
cracks. Cracks are defined in paragraph 2.D.(4) of British Aerospace
Jetstream Series 3100 & 3200 Service Bulletin 32-JA090240, Revision
1, dated January 18, 2010. Replace or repair the MLG fitting
following British Aerospace Jetstream Series 3100 & 3200 Service
Bulletin 32-JA090240, Revision 1, dated January 18, 2010. Any time
the MLG fitting is repaired or replaced, do the following actions as
applicable:
(i) MLG fitting is replaced with a new MLG fitting as specified
in paragraph (f)(2) of this AD: Upon accumulating 41,000 flight
cycles (landings) after replacement, eddy current inspect all the
MLG leg pivot beam fastener bores for cracks. Do the inspections
following British Aerospace Jetstream Series 3100 & 3200 Service
Bulletin 32-JA090240, Revision 1, dated January 18, 2010.
(ii) MGL fitting is repaired as specified in paragraph (f)(2) of
this AD: Upon accumulating 27,000 flight cycles (landings) after the
last repair and repetitively thereafter at intervals not to exceed
27,000 flight cycles (landings), eddy current inspect all the MLG
leg pivot beam fastener bores for cracks. Do the inspections
following British Aerospace Jetstream Series 3100 & 3200 Service
Bulletin 32-JA090240, Revision 1, dated January 18, 2010.
(3) If no cracks are found during any inspection required in
paragraph (f)(1), (f)(2)(i), or (f)(2)(ii) of this AD, repetitively
thereafter upon accumulating 27,000 flight cycles (landings) after
the last inspection, eddy current inspect all the MLG leg pivot beam
fastener bores for cracks.
(4) As of June 22, 2011 (the effective date of this AD), only
install a MLG fitting specified in paragraph (c)(1) of this AD that
has been eddy current inspected and found free of cracks following
British Aerospace Jetstream Series 3100 & 3200 Service Bulletin 32-
JA090240, Revision 1, dated January 18, 2010.
(5) Some of the compliance times of this AD are presented in
flight cycles (landings). If the total flight cycles have not been
kept, multiply the total number of airplane hours time-in-service by
0.75. For the purposes of this AD:
(i) 75 cycles equals 100 hours TIS; and
(ii) 750 cycles equals 1,000 hours TIS.
Note 1: Credit will be given for the inspection required in
paragraph (f)(1) of this AD and the corrective action required in
paragraph (f)(2) of this AD if already done before June 22, 2011
(the effective date of this AD) following British Aerospace
Jetstream Series 3100 & 3200 Service Bulletin 32-JA090240, original
issue dated April 29, 2009; and BEA Systems All Operator Message:
Ref 09-014J-1, issue 1, dated July 31, 2009.
