of the horizontal stabilizer de-icing
boots, and applicable corrective actions.
This AD also requires replacement of
single stitched de-icing boots with
improved double stitched boots, and reidentification of the modified horizontal
stabilizer leading edge. This AD was
prompted by reports of ruptured
horizontal stabilizer de-icing boots. We
are issuing this AD to address the unsafe
condition on these products.

applicable AFM, repetitive inspections
of the horizontal stabilizer de-icing
boots, and applicable corrective actions.
The NPRM also proposed to require
replacement of single stitched de-icing
boots with improved double stitched
boots, and re-identification of the
modified horizontal stabilizer leading
edge. We are issuing this AD to detect
and correct ruptured horizontal
stabilizer de-icing boots, which could
lead to complete loss of the de-icing
function within its associated zone and
severe vibrations, possibly resulting in
reduced control of the airplane.
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Union, has issued EASA AD 2017–0144,
dated August 9, 2017 (referred to after
this as the Mandatory Continuing
Airworthiness Information, or ‘‘the
MCAI’’), to correct an unsafe condition
for certain Saab AB, Saab Aeronautics
Model 340A (SAAB/SF340A) and SAAB
340B airplanes. The MCAI states:
Examining the AD Docket
Several occurrences were reported of
rupture of the horizontal stabilizer de-icing
boot in flight. In some of the reported events,
the de-icing boot had formed a large open
scoop.
This condition, if not detected and
corrected, could lead to complete loss of the
de-icing function within its associated zone
and severe vibrations, possibly resulting in
reduced control of the aeroplane.
To address this potential unsafe condition,
Saab AB, Aeronautics (hereafter referred to as
‘‘Saab’’ in this [EASA] AD) issued Alert
Operations Bulletin (AOB) No. 12 and AOB
No. 23 as temporary measures,
recommending to select Flaps 0 for landing
in the event of a suspected rupture of the
deicing boot on the horizontal stabilizer. In
addition, Saab issued SB [Service Bulletin]
340–30–094 providing instructions for
inspection of de-icing boots.
Consequently, EASA issued AD 2015–0129
[which corresponds to FAA AD 2016–13–06]
to require amendment of the applicable
Aircraft Flight Manual (AFM), repetitive
inspections of the horizontal stabilizer
deicing boots and, depending on findings,
accomplishment of applicable corrective
action(s).
Since that [EASA] AD was issued, Saab
developed an improved de-icing boot,
reinforced through double stitch lines, and
issued SB 340–30–095 providing instructions
for boot replacement.
For the reason described above, this
[EASA] AD retains the requirements of EASA
AD 2015–0129, which is superseded, and
requires replacement of single stitched
deicing boots, installed on the left-hand (LH)
and right-hand (RH) horizontal stabilizer,
with improved double stitched boots, and
reidentification of the modified horizontal
stabilizer leading edge.

Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2016–13–06,
Amendment 39–18570 (81 FR 41432,
June 27, 2016) (‘‘AD 2016–13–06’’). AD
2016–13–06 applied to certain Saab AB,
Saab Aeronautics Model 340A (SAAB/
SF340A) and SAAB 340B airplanes. The
NPRM published in the Federal
Register on April 17, 2018 (83 FR

reports of ruptured horizontal stabilizer
de-icing boots. The NPRM proposed to
continue to require a revision of the

Comments
We gave the public the opportunity to
participate in developing this final rule.
We received no comments on the NPRM
or on the determination of the cost to
the public.
Conclusion
We reviewed the relevant data and
determined that air safety and the
public interest require adopting this
final rule as proposed, except for minor
editorial changes. We have determined
that these minor changes:
• Are consistent with the intent that
was proposed in the NPRM for
addressing the unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the NPRM.
Related Service Information Under 1
CFR Part 51
Saab AB, Saab Aeronautics has issued
the following service information.
• Service Bulletin 340–30–094, dated

Costs of Compliance
We estimate that this AD affects 51
airplanes of U.S. registry.
The actions required by AD 2016–13–
06, and retained in this AD take about
6 work-hours per product, at an average
labor rate of $85 per workhour. Based
on these figures, the estimated cost of
the actions that are required by AD
2016–13–06 is $510 per product.
E:\FR\FM\13SER1.SGM

Federal Register / Vol. 83, No. 178 / Thursday, September 13, 2018 / Rules and Regulations
In addition, we estimate that any
necessary follow-on actions required by
AD 2016–13–06, and retained in this AD
take about 6 work-hours and require
parts costing $9,500, for a cost of
$10,010 per product. We have no way
of determining the number of aircraft
that might need these actions.
We also estimate that it would take
about 6 work-hours per product to
comply with the basic requirements of
this AD. The average labor rate is $85
per work-hour. Required parts would
cost about $13,500 per product. Based
on these figures, we estimate the cost of
this AD on U.S. operators to be
$714,510, or $14,010 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.
This AD is issued in accordance with
authority delegated by the Executive
Director, Aircraft Certification Service,
as authorized by FAA Order 8000.51C.
In accordance with that order, issuance
of ADs is normally a function of the
Compliance and Airworthiness
Division, but during this transition
period, the Executive Director has
delegated the authority to issue ADs
applicable to transport category
airplanes to the Director of the System
Oversight Division.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2016-13-06, Amendment 39-18570 (81 FR 41432,
June 27, 2016) (``AD 2016-13-06''). AD 2016-13-06 applied to certain
Saab AB, Saab Aeronautics Model 340A (SAAB/SF340A) and SAAB 340B
airplanes. The NPRM published in the Federal Register on April 17, 2018
(83 FR 16792). The NPRM was prompted by reports of ruptured horizontal
stabilizer de-icing boots. The NPRM proposed to continue to require a
revision of the applicable AFM, repetitive inspections of the
horizontal stabilizer de-icing boots, and applicable corrective
actions. The NPRM also proposed to require replacement of single
stitched de-icing boots with improved double stitched boots, and re-
identification of the modified horizontal stabilizer leading edge. We
are issuing this AD to detect and correct ruptured horizontal
stabilizer de-icing boots, which could lead to complete loss of the de-
icing function within its associated zone and severe vibrations,
possibly resulting in reduced control of the airplane.
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union, has issued EASA AD
2017-0144, dated August 9, 2017 (referred to after this as the
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to
correct an unsafe condition for certain Saab AB, Saab Aeronautics Model
340A (SAAB/SF340A) and SAAB 340B airplanes. The MCAI states:
Several occurrences were reported of rupture of the horizontal
stabilizer de-icing boot in flight. In some of the reported events,
the de-icing boot had formed a large open scoop.
This condition, if not detected and corrected, could lead to
complete loss of the de-icing function within its associated zone
and severe vibrations, possibly resulting in reduced control of the
aeroplane.
To address this potential unsafe condition, Saab AB, Aeronautics
(hereafter referred to as ``Saab'' in this [EASA] AD) issued Alert
Operations Bulletin (AOB) No. 12 and AOB No. 23 as temporary
measures, recommending to select Flaps 0 for landing in the event of
a suspected rupture of the deicing boot on the horizontal
stabilizer. In addition, Saab issued SB [Service Bulletin] 340-30-
094 providing instructions for inspection of de-icing boots.
Consequently, EASA issued AD 2015-0129 [which corresponds to FAA
AD 2016-13-06] to require amendment of the applicable Aircraft
Flight Manual (AFM), repetitive inspections of the horizontal
stabilizer deicing boots and, depending on findings, accomplishment
of applicable corrective action(s).
Since that [EASA] AD was issued, Saab developed an improved de-
icing boot, reinforced through double stitch lines, and issued SB
340-30-095 providing instructions for boot replacement.
For the reason described above, this [EASA] AD retains the
requirements of EASA AD 2015-0129, which is superseded, and requires
replacement of single stitched deicing boots, installed on the left-
hand (LH) and right-hand (RH) horizontal stabilizer, with improved
double stitched boots, and reidentification of the modified
horizontal stabilizer leading edge.
You may examine the MCAI in the AD docket on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2018-
0271.
Comments
We gave the public the opportunity to participate in developing
this final rule. We received no comments on the NPRM or on the
determination of the cost to the public.
Conclusion
We reviewed the relevant data and determined that air safety and
the public interest require adopting this final rule as proposed,
except for minor editorial changes. We have determined that these minor
changes:
Are consistent with the intent that was proposed in the
NPRM for addressing the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.
Related Service Information Under 1 CFR Part 51
Saab AB, Saab Aeronautics has issued the following service
information.
Service Bulletin 340-30-094, dated March 27, 2015. This
service information describes procedures for repetitive detailed
inspections of the de-icing boots installed on the horizontal
stabilizers, and repair and replacement of damaged de-icing boots.
Service Bulletin 340-30-095, dated April 3, 2017. This
service information describes procedures for replacement of single
stitched de-icing boots with improved double stitched boots, and re-
identification of the modified horizontal stabilizer leading edge.
Saab AB, Saab Aeronautics has also issued the following AFMs, which
describe performance limitations and general data. These AFMs are
distinct since they apply to different airplane models in different
configurations.
AFM 340A 001, Revision 57, dated March 27, 2015.
AFM 340B 001, Revision 35, dated March 27, 2015.
AFM 340B 010, Revision 28, dated March 27, 2015.
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.
Costs of Compliance
We estimate that this AD affects 51 airplanes of U.S. registry.
The actions required by AD 2016-13-06, and retained in this AD take
about 6 work-hours per product, at an average labor rate of $85 per
workhour. Based on these figures, the estimated cost of the actions
that are required by AD 2016-13-06 is $510 per product.
[[Page 46379]]
In addition, we estimate that any necessary follow-on actions
required by AD 2016-13-06, and retained in this AD take about 6 work-
hours and require parts costing $9,500, for a cost of $10,010 per
product. We have no way of determining the number of aircraft that
might need these actions.
We also estimate that it would take about 6 work-hours per product
to comply with the basic requirements of this AD. The average labor
rate is $85 per work-hour. Required parts would cost about $13,500 per
product. Based on these figures, we estimate the cost of this AD on
U.S. operators to be $714,510, or $14,010 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.
This AD is issued in accordance with authority delegated by the
Executive Director, Aircraft Certification Service, as authorized by
FAA Order 8000.51C. In accordance with that order, issuance of ADs is
normally a function of the Compliance and Airworthiness Division, but
during this transition period, the Executive Director has delegated the
authority to issue ADs applicable to transport category airplanes to
the Director of the System Oversight Division.
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 that 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);
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.
