A third U.S. pilots’ union is raising concerns about what it says is a lack of information provided by Boeing Co. on a safety system installed on the new 737 Max aircraft that is under a spotlight after last month’s crash off the coast of Indonesia.
The operations director at Lion Air, the carrier that crashed last month, also expressed frustration in an interview Thursday with what he called a lack of information on that safety feature. “There are no details” about the Maneuvering Characteristics Augmentation System in Boeing’s latest manual updates, said Zwingly Silalahi.
