737 Max Fix possibly delayed by government shutdown

Despite two crashes within six months, a growing number of grounding orders worldwide for the Boeing 737 MAX, and a number of recent complaints from US pilots over problems with the aircraft’s automatic trim controls, the Federal Aviation Administration continues to allow the 737 MAX to fly. The MCAS software update includes a new “enhanced flight control law,” a Boeing spokesperson said, which “incorporates [AOA] inputs, limits stabilizer trim commands in response to an erroneous angle of attack reading, and provides a limit to the stabilizer command in order to retain elevator authority.” On March 13, the European Union’s civil aviation authorities joined China, Australia, Singapore, Ethiopia, Malaysia, the United Kingdom, and a number of Latin American air carriers in grounding Boeing 737 MAX aircraft after the crash of the Ethiopian Airlines flight just after take-off on March 10.
