(g) Flight Demonstration.
(1) Before approval of the SAR
system, an acceptable flight
demonstration of all coupled SAR
modes is required.
(2) The AFCS must provide fail-safe
operations during coupled maneuvers.
The demonstration of fail-safe
operations must include a pilot
workload assessment associated with
manually flying the aircraft to an
altitude greater than 200 feet above the
surface and an airspeed of at least the
best rate of climb airspeed (Vy).
(3) For any failure condition of the
SAR system shown to not be extremely
improbable, the pilot must be able to
make a smooth transition from one
flight mode to another without
exceptional piloting skill, alertness, or
strength.
(4) Failure conditions that are shown
to not be extremely improbable must be
demonstrated by analysis, ground
testing, or flight testing. For failures
demonstrated in flight, the following
normal pilot recovery times are
acceptable:
(i) Transition modes (Cruise-to-Hover/
Hover-to-Cruise) and Hover modes:
Normal pilot recognition plus 1 second.
(ii) Cruise modes: Normal pilot
recognition plus 3 seconds.
(5) All AFCS malfunctions must
include evaluation at the low-speed and
high-power flight conditions typical of
SAR operations. Additionally, AFCS
hard-over, slow-over, and oscillatory
malfunctions, particularly in yaw,
require evaluation. AFCS malfunction
testing must include a single or a
combination of failures (such as,
erroneous data from and loss of the
radio altimeter, attitude, heading, and
altitude sensors) that are shown to not
be extremely improbable.
(6) The flight demonstration must
include the following environmental
conditions:
(i) Swell into wind.
(ii) Swell and wind from different
directions.
(iii) Cross swell.
(iv) Swell of different lengths (short
and long swell).

SUPPLEMENTARY INFORMATION:
Discussion
On April 7, 2017, we issued AD 2017–
08–07, Amendment 39–18856 (82 FR
18084, April 17, 2017) (‘‘AD 2017–08–
07’’), for Learjet, Inc., Model 60
airplanes, serial numbers 60–002
through 60–430 inclusive. AD 2017–08–
07 required a one-time inspection of the
fuselage skin for corrosion, and related
investigative and corrective actions if
necessary. AD 2017–08–07 resulted
from an evaluation by the design
approval holder (DAH) indicating that
the upper fuselage skin under the aft
oxygen line fairing is subject to multisite damage (MSD). We issued AD
2017–08–07 to detect and correct
corrosion of the fuselage skin, which
could result in reduced structural
integrity of the airplane.
Actions Since AD 2017–08–07 Was
Issued
Since we issued AD 2017–08–07, we
determined that only certain airplanes
identified in the applicability of AD
2017–08–07 are affected by the unsafe
condition. For Learjet, Inc., Model 60
airplanes, serial numbers 60–002
through 60–430 inclusive, the unsafe
condition affects only airplanes with a
dorsal-mounted oxygen bottle and
E:\FR\FM\30MYR1.SGM
30MYR1
Federal Register / Vol. 82, No. 102 / Tuesday, May 30, 2017 / Rules and Regulations
airplanes that have had the dorsalmounted oxygen bottle removed but
have retained the oxygen line fairing
installed on top of the fuselage. These
airplanes are identified in the effectivity
of Learjet 60 Service Bulletin 60–53–19,
Revision 3, dated August 29, 2016,
which is the appropriate source of
service information for accomplishing
the actions required by AD 2017–08–07.
Therefore, we have revised paragraph
(c) of this AD to identify only those
airplanes affected by the unsafe
condition.
Related Service Information Under 1
CFR Part 51
We reviewed Learjet 60 Service
Bulletin 60–53–19, Revision 3, dated
August 29, 2016. The service
information describes procedures for
inspections of the fuselage crown skin
for corrosion, and related investigative
and corrective actions if necessary. This
service information is reasonably
available because the interested parties
have access to it through their normal
course of business or by the means
identified in the ADDRESSES section.
FAA’s Determination
We are issuing this AD because we
evaluated all the relevant information
and determined the unsafe condition
described previously is likely to exist or
develop in other products of the same
type design.
AD Requirements
This AD requires a one-time
inspection of the fuselage skin for
corrosion, and related investigative and
corrective actions if necessary. This AD
also requires sending the inspection
results to the FAA.
Differences Between This AD and the
Service Information
Learjet 60 Service Bulletin 60–53–19,
Revision 3, dated August 29, 2016,
specifies to contact the manufacturer for
instructions on how to repair certain
conditions, but this AD requires
repairing those conditions in one of the
following ways:
• In accordance with a method that
we approve; or
• Using data that meet the
certification basis of the airplane, and
that have been approved by a Delegated
Engineering Representative (DER) for
Learjet Inc., or a Unit Member (UM) of
the Learjet Organization Designation
Authorization (ODA), whom we have
authorized to make those findings.
Interim Action
We consider this AD interim action.
Because the cause of the corrosion is not
known, the inspection reports will help
determine the extent of the corrosion in
the affected fleet. Based on the results
of these reports, we might determine
that further corrective action is
warranted. Once further corrective
action has been identified, we might
consider further rulemaking.
FAA’s Justification and Determination
of the Effective Date
We determined that unaffected
airplanes were inadvertently included
in the applicability of AD 2017–08–07,
which applied to Learjet, Inc., Model 60
airplanes, serial numbers 60–002
through 60–430 inclusive. However,
only airplanes identified in Learjet 60
Service Bulletin 60–53–19, Revision 3,
dated August 29, 2016, are subject to the
identified unsafe condition. The actions
required by this AD are not required to
24463
be done on airplanes that are not
identified in Learjet 60 Service Bulletin
60–53–19, Revision 3, dated August 29,
2016. Therefore, we are superseding AD
2017–08–07 to correct the applicability.
We find that notice and opportunity for
prior public comment are unnecessary
and that good cause exists for making
this amendment effective in less than 30
days.
Comments Invited
This AD is a final rule that involves
requirements affecting flight safety and
was not preceded by notice and an
opportunity for public comment.
However, we invite you to send any
written data, views, or arguments about
this AD. Send your comments to an
address listed under the ADDRESSES
section. Include the docket number
FAA–2017–0501 and Directorate
Identifier 2017–NM–053–AD at the
beginning of your comments. We
specifically invite comments on the
overall regulatory, economic,
environmental, and energy aspects of
this AD. We will consider all comments
received by the closing date and may
amend this AD because of those
comments.
We will post all comments we
receive, without change, to https://
www.regulations.gov, including any
personal information you provide. We
will also post a report summarizing each
substantive verbal contact we receive
about this AD.
Costs of Compliance
We estimate that this AD affects 284
airplanes of U.S. registry. We estimate
the following costs to comply with this
AD:

According to the manufacturer, some
of the costs of this AD may be covered
under warranty, thereby reducing the
cost impact on affected individuals. We
do not control warranty coverage for
affected individuals. As a result, we
have included all known costs in our
cost estimate.

PART 39—AIRWORTHINESS
DIRECTIVES
1. The authority citation for part 39
continues to read as follows:
■
Authority: 49 U.S.C. 106(g), 40113, 44701.
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
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),
(3) Will not affect intrastate aviation
in Alaska, and
(4) 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.

ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: We are superseding Airworthiness Directive (AD) 2017-08-07 for
certain Learjet, Inc., Model 60 airplanes. AD 2017-08-07 required a
one-time inspection of the fuselage skin for corrosion, and related
investigative and corrective actions if necessary. This new AD retains
the actions of AD 2017-08-07 and removes certain airplanes from the
applicability. This AD was prompted by a determination that only
certain airplanes are affected by the unsafe condition. We are issuing
this AD to address the unsafe condition on these products.

SUPPLEMENTARY INFORMATION:
Discussion
On April 7, 2017, we issued AD 2017-08-07, Amendment 39-18856 (82
FR 18084, April 17, 2017) (``AD 2017-08-07''), for Learjet, Inc., Model
60 airplanes, serial numbers 60-002 through 60-430 inclusive. AD 2017-
08-07 required a one-time inspection of the fuselage skin for
corrosion, and related investigative and corrective actions if
necessary. AD 2017-08-07 resulted from an evaluation by the design
approval holder (DAH) indicating that the upper fuselage skin under the
aft oxygen line fairing is subject to multi-site damage (MSD). We
issued AD 2017-08-07 to detect and correct corrosion of the fuselage
skin, which could result in reduced structural integrity of the
airplane.
Actions Since AD 2017-08-07 Was Issued
Since we issued AD 2017-08-07, we determined that only certain
airplanes identified in the applicability of AD 2017-08-07 are affected
by the unsafe condition. For Learjet, Inc., Model 60 airplanes, serial
numbers 60-002 through 60-430 inclusive, the unsafe condition affects
only airplanes with a dorsal-mounted oxygen bottle and
[[Page 24463]]
airplanes that have had the dorsal-mounted oxygen bottle removed but
have retained the oxygen line fairing installed on top of the fuselage.
These airplanes are identified in the effectivity of Learjet 60 Service
Bulletin 60-53-19, Revision 3, dated August 29, 2016, which is the
appropriate source of service information for accomplishing the actions
required by AD 2017-08-07. Therefore, we have revised paragraph (c) of
this AD to identify only those airplanes affected by the unsafe
condition.
Related Service Information Under 1 CFR Part 51
We reviewed Learjet 60 Service Bulletin 60-53-19, Revision 3, dated
August 29, 2016. The service information describes procedures for
inspections of the fuselage crown skin for corrosion, and related
investigative and corrective actions if necessary. This service
information is reasonably available because the interested parties have
access to it through their normal course of business or by the means
identified in the ADDRESSES section.
FAA's Determination
We are issuing this AD because we evaluated all the relevant
information and determined the unsafe condition described previously is
likely to exist or develop in other products of the same type design.
AD Requirements
This AD requires a one-time inspection of the fuselage skin for
corrosion, and related investigative and corrective actions if
necessary. This AD also requires sending the inspection results to the
FAA.
Differences Between This AD and the Service Information
Learjet 60 Service Bulletin 60-53-19, Revision 3, dated August 29,
2016, specifies to contact the manufacturer for instructions on how to
repair certain conditions, but this AD requires repairing those
conditions in one of the following ways:
In accordance with a method that we approve; or
Using data that meet the certification basis of the
airplane, and that have been approved by a Delegated Engineering
Representative (DER) for Learjet Inc., or a Unit Member (UM) of the
Learjet Organization Designation Authorization (ODA), whom we have
authorized to make those findings.
Interim Action
We consider this AD interim action. Because the cause of the
corrosion is not known, the inspection reports will help determine the
extent of the corrosion in the affected fleet. Based on the results of
these reports, we might determine that further corrective action is
warranted. Once further corrective action has been identified, we might
consider further rulemaking.
FAA's Justification and Determination of the Effective Date
We determined that unaffected airplanes were inadvertently included
in the applicability of AD 2017-08-07, which applied to Learjet, Inc.,
Model 60 airplanes, serial numbers 60-002 through 60-430 inclusive.
However, only airplanes identified in Learjet 60 Service Bulletin 60-
53-19, Revision 3, dated August 29, 2016, are subject to the identified
unsafe condition. The actions required by this AD are not required to
be done on airplanes that are not identified in Learjet 60 Service
Bulletin 60-53-19, Revision 3, dated August 29, 2016. Therefore, we are
superseding AD 2017-08-07 to correct the applicability. We find that
notice and opportunity for prior public comment are unnecessary and
that good cause exists for making this amendment effective in less than
30 days.
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety and was not preceded by notice and an opportunity for public
comment. However, we invite you to send any written data, views, or
arguments about this AD. Send your comments to an address listed under
the ADDRESSES section. Include the docket number FAA-2017-0501 and
Directorate Identifier 2017-NM-053-AD at the beginning of your
comments. We specifically invite comments on the overall regulatory,
economic, environmental, and energy aspects of this AD. We will
consider all comments received by the closing date and may amend this
AD because of those comments.
We will post all comments we receive, without change, to https://www.regulations.gov, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we
receive about this AD.
Costs of Compliance
We estimate that this AD affects 284 airplanes of U.S. registry. We
estimate the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Inspection (retained action from AD 46 work-hours x $85 per $265 $4,175 $1,185,700
2017[dash]08-07). hour = $3,910.
Reporting (retained action from AD 1 work-hour x $85 per 0 85 24,140
2017[dash]08-07). hour = $85.
----------------------------------------------------------------------------------------------------------------
This AD adds no additional economic burden.
We have received no definitive data that would enable us to provide
cost estimates for the on-condition actions specified in this AD.
According to the manufacturer, some of the costs of this AD may be
covered under warranty, thereby reducing the cost impact on affected
individuals. We do not control warranty coverage for affected
individuals. As a result, we have included all known costs in our cost
estimate.
Paperwork Reduction Act
A federal agency may not conduct or sponsor, and a person is not
required to respond to, nor shall a person be subject to penalty for
failure to comply with a collection of information subject to the
requirements of the Paperwork Reduction Act unless that collection of
information displays a current valid OMB control number. The control
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in
the Costs of Compliance section of this document and includes time for
reviewing instructions, as well as completing and reviewing the
collection of information. Therefore, all reporting associated with
this AD is mandatory. Comments concerning the accuracy of this burden
[[Page 24464]]
and suggestions for reducing the burden should be directed to the FAA
at 800 Independence Ave. SW., Washington, DC 20591. ATTN: Information
Collection Clearance Officer, AES-200.
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
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),
(3) Will not affect intrastate aviation in Alaska, and
(4) 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.
