Why only one engine when both of the props were bent? Surely the second one should have been replaced as well? And if the upper IB wing skin was disbonded surely it shouldn't have been flown like that? Something doesn't add up here.
Only 1 engine was US. A damaged prop doesn't necessarily mean a damaged engine. Disbonding on the upper IB wing skin panel is very common on the early Kingair. You can easily get a EO/EA from Beechcraft or any authorised engineering company to keep flying (it's not a wet wing). It's time limited and inspections in that area increase. There also is a temporary repair in the SRIM.
The multiple punctures in the fuse were the issue. It flew to Sunshine coast on special permit with altitude restrictions.
