The union for Southwest Airlines Co. pilots sued Boeing Co., saying the manufacturer rushed output of the 737 Max jet to stay competitive, withholding key information about a feature that contributed to two fatal crashes within five months.

¡°Boeing made a calculated decision to rush a re-engined aircraft to market to secure its single-aisle market share and prioritize its bottom line,¡± said the Southwest Airlines Pilots Association suit. The union said it¡¯s seeking at least $115 million for damages sustained through the end of this year, primarily for lost pay and legal expenses.

¡°Boeing abandoned sound design and engineering practices, withheld safety critical information from regulators and deliberately misled its customers, pilots and the public about the true scope of design changes,¡± the suit said.
