Well before any PIA took place during the dispute of last year the ALAEA offered Qantas pretty much what you suggested here. We offered, no transit check, no LAME on departure but we demanded there be one for each arrival so we could fix the broken ones. Qantas said no because they want everything and more. Don't think that the ALAEA incapable of being co-operative or progressive.
Representing AMEs and LAMEs together is not a conflict of interest. Both groups have long sought one representing body. AMEs currently sit in big unions and the aviation sectors are about 1% of the membership of that union. What say do you think they get and how much do you think their leaders know about our industry?
So Fedsellout, of all aircraft arrivals for QF how many are required the attention of a LAME on arrival?
Remember before you answer I perform this role at VA.
