AN LAME-I agree with you it shouldn't be happening but it is. As a comparison how long ago were there 4 man crews in a cockpit.A -400 jumbo now has 2.
With the shortage (?) of licences and the way the rest of the world operates this move in AUS is unavoidable.
An actual percentage of maintenance reports saying "NIL" would not back up your/our cause.
Boeing themselves are advising new aircraft customers that a plane can fly for 10 days without seeing an engineer.
Unfortunatly until there is an incident,more so loss of life,licences won't be req'd on tarmac.
