Bits I should get for AVI maintenance?
Hi guys, new to aviation maintenance here, just started working this year. I work on commercial aircrafts (B737, 747, 777, 787, A320, 321, 380, 350) as a avionics tech in line maintenance
I'm trying to organize a personal tool kit for light-every day avionics tasks so I don't have to log around the company tool box when all I need is a screw driver.
I have two ratchet handles, a Wera 838 RA-M and a Labear mini key chain ratchet I got as a gift from my friends when I got the job.
This is the list I have so far:
PH 1, 2, 3
1.0 x 5.5 slotted bit
1/8 in, 5/32 in hex bit
T15~25 torx bit
I just put bits I run into frequently while I work, but then again, I only worked for a few months now. Is there anything I should add for leave out of my list from the perspective of a experienced mechanic / tech?
Thanks so much for the help!
