Kabo bought a former Corsair 744, but defaulted on payment to the lender and the repair station that was doing the heavy check. I think the plane did receive a "5N" registration, but it is probably in legal limbo awaiting action by the banks involved.
Kabo has always had a bad reputation for paying crew.....even in years when they were profitable. Because of this they've been unable to recruit 742 cockpit crews from the Western world. Kabo's crews last season came mostly from Iran and Indonesia.
Kabo is having severe financial problems now and most of their Hajj flights were contracted out this past season. They have shrunk dramatically in the past few years and I don't know how much longer they can survive.
