Revision Log
Introduction
This document is the Federal Aviation Administration (FAA) Approved Model List (AML) for Supplemental Type Certificate (STC) Number SA01134DE, for installing the EarthX Inc. ETX680-24-TSO Battery into eligible aircraft. Revisions to the AML must be coordinated between the STC holder and the responsible Certification Branch and require FAA approval. This AML is only applicable to the aircraft listed in paragraph 4.
Prerequisites
For a serial number of an approved model (see paragraph 4) to be eligible for
this STC installation, certain equipment must be installed (See paragraph 2.2,
limitation 1)
Limitations
Limitations – All models:
| Limitation Number | Limitations for ALL models |
|---|---|
| 1 | To prevent battery overcharging, Over Voltage Protection (OVP) means/ |
equipment in the battery charging system is required.
2
| The installer must determine if this design change is compatible with previously approved modifications.
3
| The modified airplane must be maintained in accordance with the Instructions
for Continued Airworthiness (ICA) document.
4| A copy of this certificate must be maintained as part of the permanent
records for the modified aircraft.
5
| If the holder agrees to permit another person to use this certificate, the
holder shall give the other person written evidence of that permission.
6| Installation limited to 28 DC volts electrical systems.
Certification Basis
The certification basis for each qualified model listed in paragraph 4 is as specified in its Type Certificate Datasheet (TCDS) and as modified by this STC’s type design at the amendment levels noted in below:
All Models (Rows 1-4)

SO No| Safety Objectives
---|---
1| Be designed to maintain safe cell temperatures and pressures under all foreseeable operating conditions to prevent fire and explosion.
2| Be designed to prevent the occurrence of self-sustaining, uncontrollable increases in temperature or pressure, and automatically control the charge rate of each cell to protect against adverse operating
conditions, such as cell imbalance, back charging, overcharging, and overheating.
3| Not emit explosive or toxic gases, either in normal operation or as a
result of its failure, that may accumulate in hazardous quantities within the
airplane
4| Meet the requirements of §23.2325(g).
5| Not damage surrounding structure or adjacent systems, equipment,
components, or electrical wiring from corrosive or any other fluids or gases
that may escape in such a way as to cause a major or more-
severe failure condition.
6| Have provisions to prevent any hazardous effect on airplane structure or
systems caused by the maximum amount of heat it can generate due to any
failure of it or its individual cells.
7| Have a failure sensing and warning system to alert the flight crew if its
failure affects safe operation of
the airplane.
8| Have a monitoring and warning feature that alerts the flight crew when its
charge state falls below acceptable levels if its function is required for
safe operation of the airplane.
9| Have a means to disconnect from its charging source in the event of an
over-temperature condition, cell failure or battery failure.
