Pilots offer insights on Boeing 737 crashes

The FAA issued an emergency grounding of all U.S.-operated Boeing 737 MAX-8 and -9 aircraft after collecting “new evidence” from the site of a deadly jetliner crash in Ethiopia amid increased fallout from the traveling public. Tecce noted that in the case of the Lion Air Boeing 737 MAX crash, “now the airplane is pitching down and actually moving the control wheel will not stop that system. If the pilot uses the trim system on the yoke, the [MCAS] system will stop” but “if the airplane isn’t in the proper attitude it will reactivate,” Tecce said, further forcing the aircraft downward if pilots fail to recognize the situation and take proper corrective action.
