SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for all
Short Brothers Model SD3 airplanes.
This AD requires installing additional
fuel tank bonding jumpers, performing
an in-place resistance check of the float
switches, inspecting certain internal
components of the fuel tanks, and
performing related corrective actions if
necessary. This AD also requires
revisions to the Airworthiness
Limitations section of the Instructions
for Continued Airworthiness, and to the
airplane flight manual procedures for
operation during icing conditions and
fuel system failures. This AD results

from fuel system reviews conducted by
the manufacturer. We are issuing this
AD to prevent ignition sources inside
the fuel tanks, which could lead to fire
or explosion.
DATES: This AD becomes effective July
21, 2006.
The Director of the Federal Register
approved the incorporation by reference
of certain publications listed in the AD
as of July 21, 2006.

ADDRESSES
Discussion
The FAA issued a supplemental
notice of proposed rulemaking (NPRM)
to amend 14 CFR part 39 to include an
AD that would apply to all Short
Brothers Model SD3 airplanes. That
supplemental NPRM was published in
the Federal Register on April 12, 2006
(71 FR 18686). That supplemental
NPRM proposed to require installing
additional fuel tank bonding jumpers,
performing an in-place resistance check
of the float switches, inspecting certain
internal components of the fuel tanks,
and performing related corrective
actions if necessary. That supplemental
NPRM also proposed to require
revisions to the Airworthiness
Limitations section of the Instructions
for Continued Airworthiness, and to the
airplane flight manual (AFM)
procedures for operation during icing
conditions and fuel system failures.
Comments
We provided the public the
opportunity to participate in the
development of this AD. We received no
comments on the supplemental NPRM
or on the determination of the cost to
the public.
Clarification of Service Information
We have revised the reference to the
advance amendment bulletin specified
in paragraph (f) of this AD. Rather than
one bulletin, there are four bulletins,
each applicable to a certain model
airplane. The information in each
E:\FR\FM\16JNR1.SGM
16JNR1
34802
Federal Register / Vol. 71, No. 116 / Friday, June 16, 2006 / Rules and Regulations
bulletin revises the applicable AFM for
that model airplane.
Conclusion
We have carefully reviewed the
available data and determined that air
safety and the public interest require
adopting the AD with the change
previously discussed. We have
determined that this change will neither
increase the economic burden on any
operator nor increase the scope of the
AD.
Costs of Compliance
This AD affects about 54 airplanes of
U.S. registry. The average labor rate is
estimated to be $80 per work hour.
The required revisions to the AFM
and airplane maintenance manual
(AMM) will take about 1 work hour per
airplane. Based on these figures, the
estimated cost of the required revisions
for U.S. operators is $4,320, or $80 per
airplane.
The required resistance check,
inspections, and jumper installations,
will take about 40 work hours per
airplane. Required parts will cost about
$10 per airplane. Based on these figures,
the estimated cost of these required
actions for U.S. operators is $173,340, or
$3,210 per airplane.
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 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.
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
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.
See the ADDRESSES section for a location
to examine the regulatory evaluation.

Adoption of the Amendment
Accordingly, under the authority
delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as
follows:
I
PART 39—AIRWORTHINESS
DIRECTIVES
1. The authority citation for part 39
continues to read as follows:
I
Authority: 49 U.S.C. 106(g), 40113, 44701.
§ 39.13
[Amended]
2. The Federal Aviation
Administration (FAA) amends § 39.13
by adding the following new
airworthiness directive (AD):
I
2006–12–18 Short Brothers PLC:
Amendment 39–14644. Docket No.
FAA–2005–23173; Directorate Identifier
2005–NM–190–AD.
Effective Date
(a) This AD becomes effective July 21,
2006.
Affected ADs
(b) None.
Applicability
(c) This AD applies to all Shorts Model
SD3–60 SHERPA, SD3-SHERPA, SD3–30,
and SD3–60 airplanes, certificated in any
category.
Note 1: This AD requires revisions to
certain operator maintenance documents to
include new inspections. Compliance with
these inspections is required by 14 CFR
91.403(c). For airplanes that have been
previously modified, altered, or repaired in
the areas addressed by these inspections, the
operator may not be able to accomplish the
inspections described in the revisions. In this
situation, to comply with 14 CFR 91.403(c),
the operator must request approval for an
alternative method of compliance according
to paragraph (i) of this AD. The request
should include a description of changes to
the required inspections that will ensure the
continued damage tolerance of the affected
structure. The FAA has provided guidance
for this determination in Advisory Circular
(AC) 25–1529.
Unsafe Condition
(d) This AD results from fuel system
reviews conducted by the manufacturer. We
are issuing this AD to prevent ignition
sources inside the fuel tanks, which could
lead to fire or explosion.
Compliance
(e) You are responsible for having the
actions required by this AD performed within
the compliance times specified, unless the
actions have already been done.
Revision of Airplane Flight Manual (AFM)
(f) Within 30 days after the effective date
of this AD, revise the Limitations and Normal
Procedures sections of the AFMs as specified
in Table 1 of this AD to include the
information in the applicable Shorts advance
amendment bulletins as specified in Table 1
of this AD. The advance amendment
bulletins address operation during icing
conditions and fuel system failures.
Thereafter, operate the airplane according to
the limitations and procedures in the
applicable advance amendment bulletin.
Note 2: The requirements of paragraph (f)
of this AD may be done by inserting a copy
of the applicable advance amendment
bulletin into the AFM. When the applicable
advance amendment bulletin has been
included in general revisions of the AFM, the
general revisions may be inserted into the
AFM and the advance amendment bulletin
may be removed, provided the relevant
information in the general revision is
identical to that in the advance amendment
bulletin.

SUPPLEMENTARY INFORMATION:
Discussion
On January 30, 2006, 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 the
GMD actuator nut assembly, P/N
GMD115–810029–17 or P/N GMD115–
810029–23, that is installed on certain
airplanes. This proposal was published
in the Federal Register as a notice of
proposed rulemaking (NPRM) on
February 3, 2006 (71 FR 5796). The
NPRM proposed to 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,

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 No. 1: Include the
Raytheon (Military) Models A200 (C–
12A) and A200 (C–12C) Airplanes in the
List of ‘‘Airplanes Affected’’
One commenter writes that the
applicability of the proposed AD needs
to be expanded. The commenter
explains that the Raytheon military
Models A200 (C–12A) and A200 (C–
12C) airplanes with standard landing
gear have the same actuator assemblies
as the airplanes listed in the NPRM, and
could have the affected P/N nut
installed.
We disagree with the commenter that
the applicability of the proposed AD
needs to be expanded. Although a
limited number of the affected actuator
assemblies were installed on Models
A200 (C–12A) and A200 (C–12C)
airplanes, the military operates these
airplanes and removed the affected parts
from service before the issuance of the
NPRM. Paragraph (e)(4) of this AD
prohibits the subject actuator nut
assembly from being installed on these
airplanes in the future. The AD specifies
that it applies to the subject actuator nut
assembly ‘‘installed on, but not limited
to’’ specific models listed.
We are not changing the final rule AD
based on this comment.
Comment Issue No. 2: Clarify
Applicability of AD by Identifying
Raytheon as the Manufacturer of the
Affected Airplane Models
Two commenters recommend that it
should be stated at the beginning of the
document that these defective parts are
installed on Raytheon airplanes. The
commenter explains that stating this
early in the AD action would be better
form and result in a more easily
comprehended document.
The FAA agrees with the commenters.
We will change the final rule to clearly
identify that the affected actuator

Airworthiness Directives; Short Brothers Model SD3 Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all
Short Brothers Model SD3 airplanes. This AD requires installing
additional fuel tank bonding jumpers, performing an in-place resistance
check of the float switches, inspecting certain internal components of
the fuel tanks, and performing related corrective actions if necessary.
This AD also requires revisions to the Airworthiness Limitations
section of the Instructions for Continued Airworthiness, and to the
airplane flight manual procedures for operation during icing conditions
and fuel system failures. This AD results from fuel system reviews
conducted by the manufacturer. We are issuing this AD to prevent
ignition sources inside the fuel tanks, which could lead to fire or
explosion.
DATES: This AD becomes effective July 21, 2006.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of July 21, 2006.
ADDRESSES: You may examine the AD docket on the Internet at https://
dms.dot.gov or in person at the Docket Management Facility, U.S.

SUPPLEMENTARY INFORMATION:
Examining the Docket
You may examine the airworthiness directive (AD) docket on the
Internet at https://dms.dot.gov or in person at the Docket Management
Facility office between 9 a.m. and 5 p.m., Monday through Friday,
except Federal holidays. The Docket Management Facility office
(telephone (800) 647-5227) is located on the plaza level of the Nassif
Building at the street address stated in the ADDRESSES section.
Discussion
The FAA issued a supplemental notice of proposed rulemaking (NPRM)
to amend 14 CFR part 39 to include an AD that would apply to all Short
Brothers Model SD3 airplanes. That supplemental NPRM was published in
the Federal Register on April 12, 2006 (71 FR 18686). That supplemental
NPRM proposed to require installing additional fuel tank bonding
jumpers, performing an in-place resistance check of the float switches,
inspecting certain internal components of the fuel tanks, and
performing related corrective actions if necessary. That supplemental
NPRM also proposed to require revisions to the Airworthiness
Limitations section of the Instructions for Continued Airworthiness,
and to the airplane flight manual (AFM) procedures for operation during
icing conditions and fuel system failures.
Comments
We provided the public the opportunity to participate in the
development of this AD. We received no comments on the supplemental
NPRM or on the determination of the cost to the public.
Clarification of Service Information
We have revised the reference to the advance amendment bulletin
specified in paragraph (f) of this AD. Rather than one bulletin, there
are four bulletins, each applicable to a certain model airplane. The
information in each
[[Page 34802]]
bulletin revises the applicable AFM for that model airplane.
Conclusion
We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD with the
change previously discussed. We have determined that this change will
neither increase the economic burden on any operator nor increase the
scope of the AD.
Costs of Compliance
This AD affects about 54 airplanes of U.S. registry. The average
labor rate is estimated to be $80 per work hour.
The required revisions to the AFM and airplane maintenance manual
(AMM) will take about 1 work hour per airplane. Based on these figures,
the estimated cost of the required revisions for U.S. operators is
$4,320, or $80 per airplane.
The required resistance check, inspections, and jumper
installations, will take about 40 work hours per airplane. Required
parts will cost about $10 per airplane. Based on these figures, the
estimated cost of these required actions for U.S. operators is
$173,340, or $3,210 per airplane.
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 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.
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 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. See the ADDRESSES
section for a location to examine the regulatory evaluation.

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 Federal Aviation Administration (FAA) amends Sec. 39.13 by
adding the following new airworthiness directive (AD):
2006-12-18 Short Brothers PLC: Amendment 39-14644. Docket No. FAA-
2005-23173; Directorate Identifier 2005-NM-190-AD.
Effective Date
(a) This AD becomes effective July 21, 2006.
Affected ADs
(b) None.
Applicability
(c) This AD applies to all Shorts Model SD3-60 SHERPA, SD3-
SHERPA, SD3-30, and SD3-60 airplanes, certificated in any category.
Note 1: This AD requires revisions to certain operator
maintenance documents to include new inspections. Compliance with
these inspections is required by 14 CFR 91.403(c). For airplanes
that have been previously modified, altered, or repaired in the
areas addressed by these inspections, the operator may not be able
to accomplish the inspections described in the revisions. In this
situation, to comply with 14 CFR 91.403(c), the operator must
request approval for an alternative method of compliance according
to paragraph (i) of this AD. The request should include a
description of changes to the required inspections that will ensure
the continued damage tolerance of the affected structure. The FAA
has provided guidance for this determination in Advisory Circular
(AC) 25-1529.
Unsafe Condition
(d) This AD results from fuel system reviews conducted by the
manufacturer. We are issuing this AD to prevent ignition sources
inside the fuel tanks, which could lead to fire or explosion.
Compliance
(e) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Revision of Airplane Flight Manual (AFM)
(f) Within 30 days after the effective date of this AD, revise
the Limitations and Normal Procedures sections of the AFMs as
specified in Table 1 of this AD to include the information in the
applicable Shorts advance amendment bulletins as specified in Table
1 of this AD. The advance amendment bulletins address operation
during icing conditions and fuel system failures. Thereafter,
operate the airplane according to the limitations and procedures in
the applicable advance amendment bulletin.
Note 2: The requirements of paragraph (f) of this AD may be done
by inserting a copy of the applicable advance amendment bulletin
into the AFM. When the applicable advance amendment bulletin has
been included in general revisions of the AFM, the general revisions
may be inserted into the AFM and the advance amendment bulletin may
be removed, provided the relevant information in the general
revision is identical to that in the advance amendment bulletin.
