Federal Register / Vol. 73, No. 49 / Wednesday, March 12, 2008 / Rules and Regulations
Applicability
(c) This AD applies to Models 42A, 56A,
60A, 69A, 77A, 90A, 105A, 120A, 150A,
180A, 210A, 240A, 260A, and 310A balloons
that are:
(i) Certificated in any category; and
(ii) Equipped with burners with serial
numbers BU502 through BU792, except
BU507, BU511, BU512, BU614, BU643,
BU655, BU656, BU719, BU723, BU746,
BU749, BU752, BU754, BU762, BU779,
BU781, BU785, BU787, and BU789.
Subject
(d) Air Transport Association of America
(ATA) Code 28: Fuel.
Reason
(e) The mandatory continuing
airworthiness information (MCAI) states:
Defective burner hoses have been
identified which might develop a leak. A
significant leak, if it was ignited, could
hazard the balloon and occupants.
Since the issue of AD G–2003–0010 there
have been occurrences of hose failure in
batches not identified in the earlier bulletins.
LHAB Service Bulletin (SB) No. 11
supersedes the earlier SBs and revises the
applicability as required.
The MCAI requires you inspect the hose
and to identify whether the hose is from the
affected batch of hoses and to inspect and
replace any defective hose and end fitting
from the affected batch.
Actions and Compliance
(f) Unless already done, do the following
actions:
(1) Before further flight as of April 1, 2008
(the effective date of this AD) inspect the
balloon burner to determine whether it has
a hose from the affected batch of hoses
following Lindstrand Hot Air Balloons Ltd.
Service Bulletin No. 11, Issue 1, dated
September 24, 2007.
(2) As a result of the inspection required
by (f)(1) of this AD, if you find a hose from
the affected batch, before further flight
inspect for leaks and conduct a pressure test
following Lindstrand Hot Air Balloons Ltd.
Service Bulletin No. 11, Issue 1, dated
September 24, 2007, and repetitively
thereafter inspect and conduct a pressure test
at intervals not to exceed 10 hours time-inservice.
(3) As a result of any inspection or test
required by (f)(2) of this AD, if you find a
defective hose, replace it and the end fitting
with a new hose and new end fitting before
further flight. This action terminates the
repetitive requirement in (f)(2) of this AD.
Note 1: You may replace the hose and end
fitting at any time to terminate the repetitive
inspection and testing requirements of this
AD.
(2) This AD is considered an interim action
because we are not including the mandatory
replacement terminating action in this AD
(replacement is only required by this AD if
a defective hose is found in an inspection or
test). The Administrative Procedure Act does
not permit the FAA to ‘‘bootstrap’’ a longterm requirement into an urgent safety of
flight action where the rule becomes effective
at the same time the public has the
opportunity to comment. The short-term
action and the long-term action are analyzed
separately for justification to bypass prior
public notice.
(3) After issuing this AD, we may initiate
further AD action (notice of proposed
rulemaking followed by a final rule) to
require a terminating action to the repetitive
inspection and test.
Other FAA AD Provisions
(g) The following provisions also apply to
this AD:
(1) Alternative Methods of Compliance
(AMOCs): The Manager, Standards Office,
FAA, has the authority to approve AMOCs
for this AD, if requested using the procedures
found in 14 CFR 39.19. Send information to
ATTN: Taylor Martin, Aerospace Engineer,

Room 301, Kansas City, Missouri 64106;
telephone: (816) 329–4138; fax: (816) 329–
4090. Before using any approved AMOC on
any airplane to which the AMOC applies,
notify your appropriate principal inspector
(PI) in the FAA Flight Standards District
Office (FSDO), or lacking a PI, your local
FSDO.
(2) Airworthy Product: For any requirement
in this AD to obtain corrective actions from
a manufacturer or other source, use these
actions if they are FAA-approved. Corrective
actions are considered FAA-approved if they
are approved by the State of Design Authority
(or their delegated agent). You are required
to assure the product is airworthy before it
is returned to service.
(3) Reporting Requirements: For any
reporting requirement in this AD, under the
provisions of the Paperwork Reduction Act
(44 U.S.C. 3501 et seq.), the Office of
Management and Budget (OMB) has
approved the information collection
requirements and has assigned OMB Control
Number 2120–0056.
Special Flight Permit
(h) We are not allowing any special flight
permits.

ACTION: Final rule.
AGENCY:
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:
Two incidents have been reported where
the normal hydraulic supplies were lost due
to failure/loss of the steering jack gland
housing. This has been attributed to preexisting thread damage on the steering jack
gland housing. Three previous failures may
also be due to this failure mechanism.
Failure of the steering jack gland housing
resulted in significant damage to the right
hand undercarriage bay door, and could
result in the nose landing gear jamming in a
fully or partially retracted position. Landing
in such a condition is considered as
potentially unsafe due to the degraded
control of the aircraft post touch down.

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 January 18, 2008 (73 FR
3428). That NPRM proposed to correct
an unsafe condition for the specified
products. The MCAI states:
Two incidents have been reported where
the normal hydraulic supplies were lost due
to failure/loss of the steering jack gland
housing. This has been attributed to preexisting thread damage on the steering jack
gland housing. Three previous failures may
also be due to this failure mechanism.
Failure of the steering jack gland housing
resulted in significant damage to the right
hand undercarriage bay door, and could
result in the nose landing gear jamming in a
fully or partially retracted position. Landing
in such a condition is considered as
potentially unsafe due to the degraded
control of the aircraft post touch down.
Changes to the gland have been introduced
in order to prevent further recurrence.
This AD requires you to install a
serviceable steering jack.
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
VerDate Aug<31>2005
17:40 Mar 11, 2008
Jkt 214001
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
Based on the service information, we
estimate that this AD affects about 149
products of U.S. registry. We also
estimate that it will take about 10 workhours per product to comply with the
basic requirements of this AD. The
average labor rate is $80 per work-hour.
Required parts will cost about $100 per
product.
Based on these figures, we estimate
the cost of this AD on U.S. operators to
be $134,100, or $900 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
PO 00000
Frm 00046
Fmt 4700
Sfmt 4700
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

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:
Two incidents have been reported where the normal hydraulic
supplies were lost due to failure/loss of the steering jack gland
housing. This has been attributed to pre-existing thread damage on
the steering jack gland housing. Three previous failures may also be
due to this failure mechanism.
Failure of the steering jack gland housing resulted in
significant damage to the right hand undercarriage bay door, and
could result in the nose landing gear jamming in a fully or
partially retracted position. Landing in such a condition is
considered as potentially unsafe due to the degraded control of the
aircraft post touch down.
[[Page 13116]]
We are issuing this AD to require actions to correct the unsafe
condition on these products.
DATES: This AD becomes effective April 16, 2008.
On April 16, 2008, the Director of the Federal Register approved
the incorporation by reference of certain publications listed in this
AD.

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 January 18, 2008 (73
FR 3428). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
Two incidents have been reported where the normal hydraulic
supplies were lost due to failure/loss of the steering jack gland
housing. This has been attributed to pre-existing thread damage on
the steering jack gland housing. Three previous failures may also be
due to this failure mechanism.
Failure of the steering jack gland housing resulted in
significant damage to the right hand undercarriage bay door, and
could result in the nose landing gear jamming in a fully or
partially retracted position. Landing in such a condition is
considered as potentially unsafe due to the degraded control of the
aircraft post touch down.
Changes to the gland have been introduced in order to prevent
further recurrence.
This AD requires you to install a serviceable steering jack.
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
Based on the service information, we estimate that this AD affects
about 149 products of U.S. registry. We also estimate that it will take
about 10 work-hours per product to comply with the basic requirements
of this AD. The average labor rate is $80 per work-hour. Required parts
will cost about $100 per product.
Based on these figures, we estimate the cost of this AD on U.S.
operators to be $134,100, or $900 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 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

reference, Safety.
Adoption of the Amendment
0
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:
2008-06-12 British Aerospace Regional Aircraft: Amendment 39-15424;
Docket No. FAA-2008-0035; Directorate Identifier 2007-CE-103-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective April
16, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Model HP.137 Jetstream Mk.1, Jetstream
Series 200,
[[Page 13117]]
Jetstream Series 3101, and Jetstream Model 3201 airplanes, all
serial numbers, certificated in any category.
Subject
(d) Air Transport Association of America (ATA) Code 32: Landing
Gear.
(e) The mandatory continuing airworthiness information (MCAI)
states:
Two incidents have been reported where the normal hydraulic
supplies were lost due to failure/loss of the steering jack gland
housing. This has been attributed to pre-existing thread damage on
the steering jack gland housing. Three previous failures may also be
due to this failure mechanism.
Failure of the steering jack gland housing resulted in
significant damage to the right hand undercarriage bay door, and
could result in the nose landing gear jamming in a fully or
partially retracted position. Landing in such a condition is
considered as potentially unsafe due to the degraded control of the
aircraft post touch down.
Changes to the gland have been introduced in order to prevent
further recurrence.
This AD requires you to install a serviceable steering jack.
Actions and Compliance
(f) Unless already done, within the next 12 months after April
16, 2008 (the effective date of this AD), install a serviceable
steering jack that has been modified following APPH Ltd. Service
Bulletin 32-78, dated February 2005, as specified in British
Aerospace Jetstream Series 3100 and 3200 Service Bulletin 32-JM5417,
Original Issue: March 22, 2005.
