WICHITA, Kan. (AP) — A dispute over a $354 million U.S. Air Force contract to build a light air support plane for use in Afghanistan has returned to court.

Sierra Nevada Corp. sued Tuesday in the U.S. Court of Federal Claims seeking reinstatement of the contract.

The Air Force rescinded the contract and opened an investigation earlier this year after Hawker Beechcraft Corp. said it was wrongly excluded from the bidding process.

Sparks, Nevada-based Sierra Nevada Corp. says cancellation of the contract is an extreme response to Air Force paperwork errors and that the revised bid proposal is tilted in favor of the competition.

Wichita, Kan.-based Hawker Beechcraft declined to comment on the filing.

At stake is a contract that ultimately could be worth nearly $1 billion, depending on future orders.
