qf1,
I neither support nor disagree woth S of F's comments however I detect a considerable chip on your shoulder. A/C transits and wheel changes are but only two of the numerous facets of terminal and servicing duties. Dare I suggest you have an inferiority complex that would show up like dogs nuts outside of your HM comfort zone.
Remember we are all LAME/AME's at the end of the day and should be closing ranks at a time like this at QF.
