US pilot unions get subpoenas for Boeing 737 Max documents

Bloomberg

Pilots’ unions at Southwest Airlines Co, United Continental Holdings Inc and American Airlines Group Inc received federal grand jury subpoenas for documents relating to Boeing Co’s grounded 737 Max.
The Southwest Airlines Pilots Association was given until May 24 to comply with the demand from the US Justice Department’s criminal division, union President Jon Weaks said. The Air Line Pilots Association, which represents aviators at United and other carriers, said it also received a subpoena. The Allied Pilots Association, whose members work for American, got one as well, said a person familiar with the matter.
Investigators are probing Boeing’s development of the Max, a popular single-aisle model that’s been grounded since mid-March after crashing twice in five months. In both disasters, a new software system known as MCAS repeatedly shoved the nose of the doomed jets down, eventually overwhelming pilots. Congress and the Transportation Department also are examining the Federal Aviation Administration’s approval of the aircraft.
“I don’t know what aspect they are investigating,” Weaks said. “They just want to know what we have on the Max. We knew it would come eventually.”
The Southwest pilots’ union will probably seek an extension of the deadline because of the time needed to search through documents, emails and other papers for Max-related items, he said.
Southwest has the largest Max fleet, with 34 planes and additional orders for more than 200. American has 24 of the jets, while United has 14.
At least one former Boeing engineer has also been subpoenaed in connection with the Max, the best-selling plane in the company’s history.
US investigators began a probe weeks after a Lion Air Max 8 plunged into the Java Sea off the coast of Indonesia on October 29.
