Hawker Beechcraft Inc., the business-jet maker partly owned by Goldman Sachs Group Inc., plans to emerge from bankruptcy as a stand-alone company after a sale to Superior Aviation Beijing Co. collapsed, Bloomberg News reported yesterday. A review of strategic alternatives for the Hawker jet line is under way, and that business may close "if no satisfactory bids are received," according to the company. The post-bankruptcy company would be renamed Beechcraft Corp. and focus on planes including civilian turboprops and military trainers. The failed $1.79 billion deal with Superior may rekindle interest in Wichita, Kansas-based Hawker.
