mountain bear, where did you get this nonsense. The care of duty comes with the licence and with following company procedures which would state, do it by the book.
what are you smoking?
in addition FAA regs state that:
(b) A certificated mechanic may not exercise the privileges of his certificate and rating unless he understands the current instructions of the manufacturer, and the maintenance manuals, for the specific operation concerned.
How anyone can justify no punishment here after 100+ innocent souls have perished amazes me. Complete dereliction of duty. Sorry buts that reality
