Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
The FAA proposes to adopt a
new airworthiness directive (AD) for
various airplanes modified with certain
configurations of Garmin G3X Touch
Electronic Flight Instrument System
installed per Supplemental Type
Certificate (STC) No. SA01899WI or

Background
The FAA was notified of a Piper
production line issue with the
installation of a Garmin G3X Touch
Electronic Flight Instrument System
installed under STC No. SA01899WI.
After calibration and fueling the
airplane to a known level, the flight
crew noted that the fuel quantity
indicator displayed a higher level of
fuel.
The Garmin G3X Touch Electronic
Flight Instrument System, when
interfaced with the Garmin GEA 24
(Engine Airframe Adapter) for display of
the fuel quantity, uses a 1K ohm resistor
inline between the GEA 24 and the
airplane fuel quantity resistance style
sending unit (float). This resistor
provides lightning protection to the fuel
tank as required by 14 CFR 23.954.
Use of the 1K resistor causes a GEA
error with changing resistor
temperature. The farther the actual
(ambient) temperature of the resistor is
from the temperature of the fuel
quantity calibration, the larger the error.
The lower the operating resistance of
the fuel sending unit, the larger the
error. The largest errors occur in
installations with fuel sending units
having an operational range less than
100 ohms. The Garmin GI 275 MFDS
installed under STC No. SA02658SE,
when interfaced with the Garmin GEA
24 for display of the fuel quantity, is
also subject to this unsafe condition.
The displayed fuel quantity can have
an error as much as four gallons/fuel
tank with the display indicating four
gallons with an empty tank. This
condition, if not addressed, could result
in fuel starvation and engine shutdown
with consequent loss of airplane
control.
FAA’s Determination
The FAA is issuing this NPRM after
determining that the unsafe condition
described previously is likely to exist or
develop on other products of the same
type design.

Mandatory STC Service Bulletin No.
2135, Revision A, both dated April 23,
2021. This service information specifies
procedures for modifying the GEA 24
resistive fuel probe interface. These
documents are distinct since they apply
to different STCs. 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 ADDRESSES.
Other Related Service Information
The FAA also reviewed Master
Drawing List (MDL) Document No. 005–
01320–00, Revision 10, for STC No.
SA01899WI, and MDL Drawing No.
005–01208–41, Revision 10, for STC No.
SA02658SE, both dated April 23, 2021.
This service information contains the
type design data for installation of the
STC. Revision 10 introduces a new fuel
quantity interface and configuration to
eliminate the unsafe condition
described previously.
Proposed AD Requirements in This
NPRM
This proposed AD would require
modifying the resistive fuel probe
interface. The proposed AD would
apply to airplanes on the approved
model list for STC No. SA01899WI,
48071
installed in accordance with MDL
Document No. 005–01320–00, Revision
9 or earlier, and STC No. SA02658SE,
installed in accordance with MDL
Drawing No. 005–01208–41, Revision 9
or earlier, if the installation is interfaced
with a Garmin Engine Adapter GEA 24
connected to resistive fuel probes.
Costs of Compliance
The FAA estimates that this AD, if
adopted as proposed, would affect 920
airplanes of U.S. registry.
The FAA estimates the following
costs to comply with this proposed AD:
ESTIMATED COSTS
Action
Labor cost
Modify fuel probe interface and recalibrate
the fuel system.
8 work-hours × $85 per hour = $680 .............
The FAA has included all known
costs in its cost estimate. According to
the manufacturer, however, some of the
costs of this proposed AD may be
covered under warranty, thereby
reducing the cost impact on affected
operators.

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.
The FAA is 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
The FAA 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
VerDate Sep<11>2014

Jkt 253001
Parts cost
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) Would not affect intrastate
aviation in Alaska, and
(3) Would not have a significant
economic impact, positive or negative,
on a substantial number of small entities
under the criteria of the Regulatory
Flexibility Act.

Background
The FAA was notified of a Piper production line issue with the
installation of a Garmin G3X Touch Electronic Flight Instrument System
installed under STC No. SA01899WI. After calibration and fueling the
airplane to a known level, the flight crew noted that the fuel quantity
indicator displayed a higher level of fuel.
The Garmin G3X Touch Electronic Flight Instrument System, when
interfaced with the Garmin GEA 24 (Engine Airframe Adapter) for display
of the fuel quantity, uses a 1K ohm resistor inline between the GEA 24
and the airplane fuel quantity resistance style sending unit (float).
This resistor provides lightning protection to the fuel tank as
required by 14 CFR 23.954.
Use of the 1K resistor causes a GEA error with changing resistor
temperature. The farther the actual (ambient) temperature of the
resistor is from the temperature of the fuel quantity calibration, the
larger the error. The lower the operating resistance of the fuel
sending unit, the larger the error. The largest errors occur in
installations with fuel sending units having an operational range less
than 100 ohms. The Garmin GI 275 MFDS installed under STC No.
SA02658SE, when interfaced with the Garmin GEA 24 for display of the
fuel quantity, is also subject to this unsafe condition.
The displayed fuel quantity can have an error as much as four
gallons/fuel tank with the display indicating four gallons with an
empty tank. This condition, if not addressed, could result in fuel
starvation and engine shutdown with consequent loss of airplane
control.
FAA's Determination
The FAA is issuing this NPRM after determining that the unsafe
condition described previously is likely to exist or develop on other
products of the same type design.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Garmin Mandatory STC Service Bulletin No. 2134,
Revision A, and Garmin
[[Page 48071]]
Mandatory STC Service Bulletin No. 2135, Revision A, both dated April
23, 2021. This service information specifies procedures for modifying
the GEA 24 resistive fuel probe interface. These documents are distinct
since they apply to different STCs. 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
ADDRESSES.
Other Related Service Information
The FAA also reviewed Master Drawing List (MDL) Document No. 005-
01320-00, Revision 10, for STC No. SA01899WI, and MDL Drawing No. 005-
01208-41, Revision 10, for STC No. SA02658SE, both dated April 23,
2021. This service information contains the type design data for
installation of the STC. Revision 10 introduces a new fuel quantity
interface and configuration to eliminate the unsafe condition described
previously.
Proposed AD Requirements in This NPRM
This proposed AD would require modifying the resistive fuel probe
interface. The proposed AD would apply to airplanes on the approved
model list for STC No. SA01899WI, installed in accordance with MDL
Document No. 005-01320-00, Revision 9 or earlier, and STC No.
SA02658SE, installed in accordance with MDL Drawing No. 005-01208-41,
Revision 9 or earlier, if the installation is interfaced with a Garmin
Engine Adapter GEA 24 connected to resistive fuel probes.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 920 airplanes of U.S. registry.
The FAA estimates the following costs to comply with this proposed
AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Modify fuel probe interface and 8 work-hours x $85 per $10 $690 $634,800
recalibrate the fuel system. hour = $680.
----------------------------------------------------------------------------------------------------------------
The FAA has included all known costs in its cost estimate.
According to the manufacturer, however, some of the costs of this
proposed AD may be covered under warranty, thereby reducing the cost
impact on affected operators.
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.
The FAA is 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
The FAA 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) Would not affect intrastate aviation in Alaska, and
(3) Would not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
