The Federal Aviation Administration has grounded all Boeing 737 MAX aircraft. President Donald Trump said the U.S. was stopping domestic airlines and others from flying the aircraft in U. S. airspace as numerous other countries had already done. The Air Line Pilots Association (ALPA) says it supports the FAA’s decision to order a temporary grounding of all Boeing 737 Max aircraft that are operated by U. S. airlines or in U. S. airspace. This action includes both the Boeing 737 Max 8 and Max 9 models and comes shortly after Canada, also a late hold out, grounded them as well. FAA had resisted calls to ground the aircraft but faced intense pressure after 40 countries banned the aircraft from operating in their airspace. “New evidence collected at the site and analyzed today,” a statement by FAA said, gave them reason to exercise the ban. The new evidence, together with refined satellite data available to FAA Wednesday morning, led to the decision the agency said. Also impacting the decision is the news that at least two reports in the Aviation Safety Reporting System (commonly called NASA reports) called attention to the same or similar problems occurring in U. S. operated aircraft. Boeing has said they will upgrade their software and improve pilot training.
