3 things were issues:
1) Dornier´s support at that time was anything than good which produced quite alot of troubles for airlines when they had technical problems with their aircraft. They never really learned it in the correct way, however AvCraft Dornier finally seems to listen to customers.
2) The 328J-100/110 was a few knots slower than promised and again there was the reliablity issue due to product support. In short, the 328-110/110 did not deliver to QX
what they were promised.
3) The probably most important issue: Bombardier was able to offer a complete turboprop product line, Dornier was too relucatant to offer and launch the 528-100/110, a 50-seat version of the 328. This finally limited QX
in its ability to expand and they switched over to the Dash 8 line completely.
