That decision will be made by regulators across the world who will have to re-certify the aircraft as safe.
America's regulator, the Federal Aviation Authority, is under huge pressure to explain itself.
Politicians have accused it of giving Boeing too much freedom to certify the MAX aircraft before it took to thRead More – Source
