WICHITA, Kan. (AP) — A federal judge has set a hearing over a proposed $90 million settlement in the lawsuit by former Boeing workers over retirement plan benefits after the sale of the company’s Wichita operations.

U.S. District Judge Monti Belot on Monday scheduled the fairness hearing for Aug. 19 in federal court in Wichita.

The class-action lawsuit covers former Boeing workers who Swere participants in the company’s retirement plan in June 2005. The settlement covers Boeing workers who had at least 10 years of vesting service and were between the ages of 49 and 55 at the time they went to work at Spirit AeroSystems or its predecessor Mid-Western Aircraft systems.

Belot preliminarily approved the settlement last week. The hearing in August will help determine whether the court gives it final approval.
