I suspect it goes well beyond Cautions items 1 and 2 although I tend to go for item 1 as the appropriate clause.
Qantas for most of time as an exclusive international operator, had a 1 or 2 type fleet, ie B707 and B747,then B747 only, then B747 and B767.Once Qantas took over Australian or v.v. depending on your choice, there was a conscious fleet rationalisation. Under James Strong the fleet evolved to 4 to 5 types consisting of Dash 8s 200/300, B737, B 767 and B747 Classic and 400s.
Fleet utilisation, at least on Long Haul, was at optimum. The Classic on the NRT run which coupled with the AKL run averaged 20 hours per day excluding heavy Maintenance. Its a bit hard to do better than that in a curfew airport environment. Others which due to curfews had down time in Europe, had progressive maintenance carried out on layovers to increase utilisation.
Today across the group including contractors there are,BAe 146, F50s,F100s,A320,
A330,A380,Dash 8 200/300 and Dash 8 400s,B717,B737,B767,B787 and B747. All up 13 types.There is no way that any operator could acheive optimum utilisation or engineering with that lot.
That fleet mix is the result of total failure at board level.
