Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. 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 E:\FR\FM\27AUP1.SGM 27AUP1 Federal Register / Vol. 86, No. 164 / Friday, August 27, 2021 / Proposed Rules 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. lotter on DSK11XQN23PROD with PROPOSALS1 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 16:25 Aug 26, 2021 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: 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. § 39.13 [Amended] 2.

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

 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.
