After take off from Alice Springs some years ago bound for Darwin, in a 146, one of the outflow valves failed to close. Setting upnfor unpressurized flight, we were able to climb to FL110 and maintain the cabin < 10,000'. Additionally, we had sufficient fuel to make Darwin with reserves intact.
Shortly after making the decision to continue, the outflow unstuck, & the flight continued normally.
Alice had no spare parts, minimal engineering coverage, and the aeroplabe was full of folk who wanted to end up in Darwin, not return to Alice.
