Discussion
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Union, has issued EASA AD 2016–0195,
dated September 30, 2016 (referred to
after this as the Mandatory Continuing
Airworthiness Information, or ‘‘the
MCAI’’), to correct an unsafe condition
for certain Airbus Model A300 B4–600,
B4–600R, and F4–600R series airplanes,
Model A300 C4–605R Variant F
airplanes (collectively called Model
A300–600 series airplanes), and Model
A310 series airplanes. The MCAI states:
An operator recently reported two events
of unreliable airspeed indications.
Investigations revealed that in both events, a
Pitot heater resistance was shorted to ground.
Pitot probes are heated to prevent ice
accretion. De-icing performance of the Pitot
probe might be reduced if Pitot probe heater
degrades over time. The magnitude of deicing performance reduction will depend on
how much the heater is degraded. The Pitot
probe de-icing reduction will be hidden to
the crew (the heater current detector will not
trigger a ‘‘Heat Fault’’ because in case of
short-to-case failure the resulting current
variation will be limited).
In severe icing conditions, if de-icing
performances are significantly reduced, it
may cause unreliable airspeed events, with
no cockpit effects except erroneous airspeed
indication(s) displayed on the Primary Flight
Display (PFD) or the standby airspeed
indicators.
Unreliable airspeed indications, if not
recognized by the crew, could possibly result
in reduced control of the aeroplane.
To ensure proper crew awareness of
unreliable airspeed indication(s) situation,
Airbus introduced a dedicated Electronic
Centralised Aircraft Monitoring (ECAM)
Warning (Indicated Airspeed Discrepancy
Warning).
The following configuration is required to
enable this ECAM Warning:
—The Flight Warning Computer (FWC)
standard S17 has to be installed by
accomplishing Service Bulletins (SB)
A310–31–2144 or A300–31–6140: This
requirement was already rendered
mandatory by EASA AD 2015–0174;
—The ECAM Symbol Generator Unit (SGU),
standard W32, Part Number (P/N)
9612670332 has to be installed, by
accomplishing Service Bulletins (SB)
A310–31–2123, A300–31–6124 or SB
A300–31–6113.
For the reason described above, this
[EASA] AD requires a software standard
upgrade of the ECAM SGU.

Related Service Information Under 1
CFR Part 51
Airbus has issued the following
service information:
• Airbus Service Bulletin A300–31–
6113, Revision 03, dated July 5, 2016
(for Model A300–600 series airplanes).
• Airbus Service Bulletin A300–31–
6124, Revision 01, dated July 4, 2016
(for Model A300–600 series airplanes).
• Airbus Service Bulletin A310–31–
2123, Revision 01, dated July 1, 2016
(for Model A310 series airplanes).
The service information describes
procedures for replacement of the
ECAM SGU. These documents are
distinct since they apply to different
airplane configurations. 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 and Requirements
of This Proposed AD
This product has been approved by
the aviation authority of another
country, and is approved for operation
in the United States. Pursuant to our
26759
bilateral agreement with the State of
Design Authority, we have been notified
of the unsafe condition described in the
MCAI and service information
referenced above. We are proposing this
AD because we evaluated all pertinent
information and determined an unsafe
condition exists and is likely to exist or
develop on other products of these same
type designs.
Costs of Compliance
We estimate that this proposed AD
affects 139 airplanes of U.S. registry. We
estimate the following costs to comply
with this proposed AD:
ESTIMATED COSTS
Action
Labor cost
Parts cost
Cost per product
Cost on U.S.
operators
Replacement .......................
Up to 4 work-hours × $85 per hour = Up to $340 ............
Up to $2,360 .....
Up to $2,700 .....
Up to $375,300.

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 proposed AD
would not have federalism implications
under Executive Order 13132. This
proposed AD would 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 proposed regulation:
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);
VerDate Sep<11>2014
14:30 Jun 08, 2017
Jkt 241001
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.

II. Background, Purpose, and Legal
Basis
On April 09, 2017, the Sylvan Verona
Beach Resort Association notified the
Coast Guard that it will be conducting
a water ski show from 12:30 p.m. to 2:30
p.m. on August 13, 2017. The water ski
show to take place in the waters of Fish
Creek on the Erie Canal System
contained within the following
positions: Starting at position
43°11′37.79″ N. and 075°43′53.27″ W.,
running Northeast to position
43°11′43.15″ N. and 075°43′44.88″ W.,
then Southeast to 43°11′42.82″ N. and
075°43′43.42″ W. then Southwest to
43°11′36.90″ N. and 075°43′52.06″ W.
then returning to the point of origin.
The Captain of the Port Buffalo (COTP)
has determined that a water ski show on
a navigable waterway will pose a
significant risk to participants and the
boating public.
The purpose of this rulemaking is to
ensure the safety of vessels and the
navigable waters within the
demonstration area of the scheduled
event. Vessel traffic will be allowed to
pass through the safety zone between
demonstrations. The Coast Guard
proposes this rulemaking under
authority in 33 U.S.C. 1231.
III. Discussion of Proposed Rule
The COTP proposes to establish a
safety zone from 12:15 p.m. to 2:30 p.m.

The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union, has issued EASA AD
2016-0195, dated September 30, 2016 (referred to after this as the
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to
correct an unsafe condition for certain Airbus Model A300 B4-600, B4-
600R, and F4-600R series airplanes, Model A300 C4-605R Variant F
airplanes (collectively called Model A300-600 series airplanes), and
Model A310 series airplanes. The MCAI states:
An operator recently reported two events of unreliable airspeed
indications. Investigations revealed that in both events, a Pitot
heater resistance was shorted to ground.
Pitot probes are heated to prevent ice accretion. De-icing
performance of the Pitot probe might be reduced if Pitot probe
heater degrades over time. The magnitude of de-icing performance
reduction will depend on how much the heater is degraded. The Pitot
probe de-icing reduction will be hidden to the crew (the heater
current detector will not trigger a ``Heat Fault'' because in case
of short-to-case failure the resulting current variation will be
limited).
In severe icing conditions, if de-icing performances are
significantly reduced, it may cause unreliable airspeed events, with
no cockpit effects except erroneous airspeed indication(s) displayed
on the Primary Flight Display (PFD) or the standby airspeed
indicators.
Unreliable airspeed indications, if not recognized by the crew,
could possibly result in reduced control of the aeroplane.
To ensure proper crew awareness of unreliable airspeed
indication(s) situation, Airbus introduced a dedicated Electronic
Centralised Aircraft Monitoring (ECAM) Warning (Indicated Airspeed
Discrepancy Warning).
The following configuration is required to enable this ECAM
Warning:
--The Flight Warning Computer (FWC) standard S17 has to be installed
by accomplishing Service Bulletins (SB) A310-31-2144 or A300-31-
6140: This requirement was already rendered mandatory by EASA AD
2015-0174;
--The ECAM Symbol Generator Unit (SGU), standard W32, Part Number
(P/N) 9612670332 has to be installed, by accomplishing Service
Bulletins (SB) A310-31-2123, A300-31-6124 or SB A300-31-6113.
For the reason described above, this [EASA] AD requires a
software standard upgrade of the ECAM SGU.

Related Service Information Under 1 CFR Part 51
Airbus has issued the following service information:
Airbus Service Bulletin A300-31-6113, Revision 03, dated
July 5, 2016 (for Model A300-600 series airplanes).
Airbus Service Bulletin A300-31-6124, Revision 01, dated
July 4, 2016 (for Model A300-600 series airplanes).
Airbus Service Bulletin A310-31-2123, Revision 01, dated
July 1, 2016 (for Model A310 series airplanes).
The service information describes procedures for replacement of the
ECAM SGU. These documents are distinct since they apply to different
airplane configurations. 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 and Requirements of This Proposed AD
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with the State of Design Authority, we have
been notified of the unsafe condition described in the MCAI and service
information referenced above. We are proposing this AD because we
evaluated all pertinent information and determined an unsafe condition
exists and is likely to exist or develop on other products of these
same type designs.
Costs of Compliance
We estimate that this proposed AD affects 139 airplanes of U.S.
registry. We estimate the following costs to comply with this proposed
AD:
Estimated Costs
--------------------------------------------------------------------------------------------------------------------------------------------------------
Action Labor cost Parts cost Cost per product Cost on U.S. operators
--------------------------------------------------------------------------------------------------------------------------------------------------------
Replacement......................... Up to 4 work-hours x $85 Up to $2,360............... Up to $2,700............... Up to $375,300.
per hour = Up to $340.
--------------------------------------------------------------------------------------------------------------------------------------------------------
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 proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 proposed
regulation:
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.
