<_< -------- Bottom line here guys, is that an Airplane ain't going to fly if there's no signature on the "Airworthiness Release" in the log book by a licensed AMT!-------- Yes, that includes spare aircraft! -------- And yes, a Supervisor can do it, if he's licensed, and has the big ones to sign for work he's not done!!!
Supervisors were told not to sign logbooks anymore. The FAA explained to a bunch of us one day that management is not directly involved in the maintenance end of the operation (hands on). They manage and supervise the operation not turn the wrench. Hopefully the FAA will hold AA accountable to this policy.
