Maintenance Task: Removal/Installation of a battery

First we have to read the technical logbook or the task card to know which is the problem of the aircraft. This time we see how the pilot has reported a failure of the plane’s battery.

 We will go to the maintenance manual (AMM) of the airplane to know what we have to do and read:

REMOVAL / INSTALLATION
1-Locate the batteries of the airplane with the Ilustrated Parts Catalogue (IPC).
2-Take the safety precautions by disconnecting the circuit breakers of “Batttery” and “DC System” and marking with a card where we can read “DO NOT OPERATE”.
3-Remove the cover panel of the battery placement.
4-Cut the lockwire of the battery’s connector and disconnect the battery.
5-Remove the battery.

2-Connect the battery and lockwire the connector with a 0,021’ diameter of copper wire.
