I thought they'd leased one?
Plus, it has operated well enough since the incident, why suddenly the trouble now.
Plus the one that is down won't be coming back any time soon.
They'd be better cancelling the whole DSA operation. A couple of flights a week on a 19 seater aircraft isn't of benefit to anyone, especially considering they're still advertising double daily flights (a service they're not actually operating) but it is hardly fair on passengers who book flight only to see it cancelled because they cannot keep to their own schedule.
