Boeing failed to submit certification documents to the Federal Aviation Administration on modifications to the 737 Max jet’s Maneuvering Characteristics Augmentation System (MCAS), including significantly increasing the system’s ability to lower the aircraft’s nose automatically under certain conditions, according to a report detailing the certification timeline released Wednesday by the U.S. Department of Transportation’s Inspector General’s (IG) office.
