SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to various airplanes modified 

with certain configurations of Garmin 

G3X Touch Electronic Flight Instrument 

System installed per STC No. 

SA01899WI or Garmin GI 275 MFD 

installed per STC No. SA02658SE. The 

NPRM published in the Federal 

Register on August 27, 2021 (86 FR 

48070). The NPRM was prompted by 

notification 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 when the GEA 24 or resistor is 

subjected to significantly hotter or 

colder temperatures than the 

temperature at which the fuel gauges 

were calibrated during installation. The 

farther the actual (ambient) temperature 

of the GEA 24 or 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. In the 

NPRM, the FAA proposed to require 

modifying the resistive fuel probe 

interface. The FAA is issuing this AD to 

prevent fuel starvation and engine 

shutdown, which could result in the 

inability to arrive at the destination 

airport or a suitable alternative airport. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received comments from 

Garmin. The following presents the 

comments received on the NPRM and 

the FAA’s response to each comment. 

Requests Regarding Background 

Information 

Garmin requested the FAA correct 

certain information in the preamble. In 

the NPRM, the FAA stated that use of 

the 1K resistor causes a GEA error when 

the resistor temperature changes. 

According to Garmin, using the 1K 

resistor causes a GEA error when the 

GEA 24 temperature changes. Garmin 

further noted that 1k resistors are 

installed near the GEA 24 plug and are 

exposed to the same ambient 

temperatures. 

The FAA agrees with correcting the 

preamble and has changed this final 

rule to clarify that a GEA error results 

from the GEA 24 being subjected to 

significantly hotter or colder 

temperatures than the temperature at 

which the fuel gauges were calibrated 

during installation. The FAA disagrees 

with the requested changes regarding 

the location of the resistors. The 

commenter’s request is not supported by 

the information in the installation 

manual, which does not require the 

resistor to be installed near the GEA 24. 

Garmin also requested that the FAA 

remove the exact error amount (i.e., four 


jspears on DSK121TN23PROD with RULES1
Federal Register / Vol. 87, No. 30 / Monday, February 14, 2022 / Rules and Regulations 8159 

gallons) between the displayed fuel 

quantity and the actual amount of fuel. 

Garmin stated that due to variations in 

different aircraft system configurations, 

this amount could be misleading. 

Removing the reference to 4 gallons 

would minimize the potential 

magnitude of the error and the need for 

AD action. The FAA did not change this 

AD based on this comment. 

Garmin noted a typographical error in 

that the NPRM referred to ‘‘MFDS’’ 

instead of ‘‘MFDs.’’ 

The FAA agrees and has corrected all 

references to MFDs accordingly. 

Request Regarding Unsafe Condition 

Garmin requested that the FAA 

change the description of the inevitable 

consequence of the unsafe condition. In 

the NPRM, the FAA stated the unsafe 

condition, if not addressed, could result 

in fuel starvation and engine shutdown 

with consequent loss of airplane 

control. Garmin stated that this 

incorrectly implies that loss of airplane 

control is the inevitable consequence of 

fuel starvation and engine shutdown. 

Garmin requested the FAA revise the 

preamble to state that loss of airplane 

control is one of many possible 

outcomes. 

The FAA agrees that loss of control is 

not an inevitable result of fuel 

starvation. In the context of this event, 

the end level effect is the loss of 

powered flight to the destination 

airport. Accordingly, the FAA has 

revised the background section of the 

preamble and the unsafe condition 

paragraph of the AD to reflect that fuel 

starvation and engine shutdown could 

result in the inability to arrive at the 

destination airport or a suitable 

alternative airport. 

Request Regarding Applicability 

Garmin requested the FAA revise the 

AD to remove several airplane models 

that are not subject to the unsafe 

condition. Garmin listed these models 

as follows: The Boeing Company Model 

AT–6 (Navy SNJ–2), AT–6A (Navy SNJ– 

3), AT–6B, AT–6C (Navy SNJ–4), AT– 

6D (Navy SNJ–5), AT–6F (Navy SNJ–6), 

BC- 1A, Navy SNJ–7, and T–6G; Cessna 

Aircraft Company Model T–50 (Army 

AT–17 and UC–78 series, Navy JRC–1); 

Costruzioni Aeronautiche Tecnam 

S.P.A. Model P2006T; Daher Aircraft 

Design, LLC (type certificate previously 

held by Quest Aircraft Design, LLC) 

Model Kodiak 100; EADS–PZL 

Warszawa-Oke ̨cie S.A. Model PZL–104 

Wilga 80; Helio Alaska, Inc. Model H– 

800; Howard Aircraft Foundation Model 

DGA–15J (Army UC–70B), DGA–15P 

(Army UC–70, Navy GH–1, GH–2, GH– 

3, NH–1), and DGA–15W; Textron 

Aviation Inc. Model G17S; Thrush 

Aircraft, LLC Model 600 S–2D, S2R, 

S2R–R1340, S2R-Rl820, S2R–R3S, and 

S2R–T34; and Waco Aircraft Company 

Model YMF airplanes. 

The FAA agrees and has revised the 

list of applicable models accordingly. 

Conclusion 

The FAA reviewed the relevant data, 

considered any comments received, and 

determined that air safety requires 

adopting this AD as proposed. 

Accordingly, the FAA is issuing this AD 

to address the unsafe condition on these 

products. Except for the changes 

described previously, this AD is 

adopted as proposed in the NPRM. 

None of the changes will increase the 

economic burden on any operator. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Garmin 

Mandatory STC Service Bulletin 2134, 

Revision A, and Garmin Mandatory STC 

Service Bulletin 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 the 

ADDRESSES section. 

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. MDL Document No. 005–01320– 

00, Revision 10, dated April 23, 2021, 

introduces a new fuel quantity interface 

and configuration to eliminate the 

unsafe condition described previously. 

Costs of Compliance 

The FAA estimates that this AD 

affects 920 airplanes of U.S. registry. 

The FAA estimates the following 

costs to comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

airplane 

Cost on U.S. 

operators 

Modify fuel probe interface and recalibrate 

the fuel system.

8 work-hours × $85 per hour = $680 ............. $10 $690 $634,800 

The FAA has included all known 

costs in its cost estimate. According to 

the manufacturer, however, some of the 

costs of this 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 

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) Will not affect intrastate aviation 

in Alaska, and 


jspears on DSK121TN23PROD with RULES1
8160 Federal Register / Vol. 87, No. 30 / Monday, February 14, 2022 / Rules and Regulations 

(3) Will not have a significant

SUPPLEMENTARY INFORMATION: 

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2021–0127, 

dated May 12, 2021 (EASA AD 2021– 

0127) (also referred to as the MCAI), to 

correct an unsafe condition for certain 

Airbus SAS Model A350–941 and –1041 

airplanes. 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to certain Airbus SAS Model 

A350–941 and –1041 airplanes. The 

NPRM published in the Federal 

Register on August 18, 2021 (86 FR 

46164). The NPRM was prompted by a 

report that during type certification 

activity, it was identified that certain 

monitoring software was incorrectly 

implemented in the BCS certification 

standard. The NPRM proposed to 

require installing (updating) certain 

software for the braking and steering 

system, as specified in EASA AD 2021– 

0127. 

The FAA is issuing this AD to address 

in-service limitations related to the 

braking and steering system, which, 

under specific degraded conditions, 

could lead to a reduction in braking 

performance and potentially lead to a 

runway excursion, and result in damage 

to the airplane and injury to passengers. 

See the MCAI for additional background 

information. 

Discussion of Final Airworthiness

Comments 

The FAA received comments from 

Delta Airlines (DAL) and the Air Line 

Pilots Association, International 

(ALPA). ALPA supported the NPRM 

without change. The following presents 

the DAL comments received on the 

NPRM and the FAA’s response to each 

comment.

prerequisite service bulletins referenced 

in Airbus Service Bulletin A350–32– 

P037, dated July 30, 2019 (which is 

referenced in EASA AD 2021–0127). 

DAL stated that, depending on airplane 

configuration, the actions in the four 

prerequisite service bulletins may need 

to be done before doing the actions 

specified in referenced Airbus Service 

Bulletin A350–32–P037, dated July 30, 

2019. 

The FAA acknowledges the 

commenter’s request. If an operator 

accomplishes prerequisite service 

information specified in Airbus Service 

Bulletin A350–32–P037, dated July 30, 

2019 (which is referenced in EASA AD 

2021–0127) there is an additional cost to 

those prerequisite service information. It 

is estimated that an operator may incur 

an additional 15 work-hours and up to 

an additional $1,275 in parts cost to 

accomplish the prerequisite service 

information. However, since 

accomplishment of the prerequisite 

service information may not be required 

to accomplish the required actions of 

this AD, these costs may not apply to all 

operators. The FAA has added this 

explanation to the Cost of Compliance 

paragraph in this AD, but not the 

additional costs for accomplishing the 

prerequisite service information. 

Request To Add a Certain AD to 

Paragraph (b) of the Proposed AD 

DAL requested that the FAA add AD 

2017–18–18, Amendment 39–19027 (82 

FR 42579, September 11, 2017) (AD 

2017–18–18) to paragraph (b) of the 

proposed AD (AD 2017–18–18 requires 

repetitive on-ground power cycles to 

reset the internal timer). DAL stated that 

Airbus Service Bulletin A350–42–P010, 

dated August 14, 2018, is a required 

prerequisite for doing the actions in 

Airbus Service Bulletin A350–32–P037, 

dated July 30, 2019 (which is referenced 

in EASA AD 2021–0127), and therefore, 

is a requirement for doing the actions in 

the proposed AD. DAL commented that 

Airbus Service Bulletin A350–42–P010, 

dated August 14, 2018, was approved 

for use in alternative method of 

compliance (AMOC) AIR–676–19–298, 

dated July 22, 2019, for accomplishing 

the requirements in paragraph (g) of AD 

2017–18–18.
