One other thing I'd like to ask.

Who signed to aircraft log, returning the aircraft to service after
replacing the APU? That person should have been spanked for not testing
in accordance with tech data I'm sure was in place concerning
maintenance for that aircraft. The (avionics) shop chief (probably the
highest ranking NCO in your unit) should have lost a stripe for allowing
that to happen in the first place. You should have had your balls
flattened out in a vice because....well, just because.

I was authorized to sign equipment serviceable tags (yellow tags) and
sign off the aircraft for return to service (from the avionics
standpoint) as an E-3. I was also our midnight shift supervisor as an
E-3. How many did I supervise? One (me). Bottom line is I was able to
work alone, so I assume my shop chief had faith in my abilities.
[sarcasm mode on] Am I a hero? You betcha, cause I did my friggin'
job. [Sarcasm mode off].
