Britain's aviation authority is banning all commercial Boeing 737 MAX passenger flights from UK airspace, following Sunday's fatal plane crash in Ethiopia."We have, as a precautionary measure, issued instructions to stop any commercial passenger flights from any operator arriving, departing or overflying UK airspace," the UK Civil Aviation Authority (CAA) said in a statement.Earlier on Tuesday, aviation authorities in Singapore, Australia, Malaysia and Oman temporarily suspended Boeing 737 MAX services after Sunday's MAX 8 flight from Addis Ababa to Nairobi reported technical problems and asked for permission to turn back, before crashing into a field six minutes after takeoff, killing all 157 people on board. Investigations are taking place into the cause of the crash.This is the second time in less than six months that this model has crashed soon after taking off. A new Lion Air Boeing 737 MAX 8 flight went down over the Java Sea off Indonesia last October, killing 189 people."Our thoughts go out to everyone affected by the tragic incident in Ethiopia on Sunday," a CAA spokesperson said in a statement."The UK Civil Aviation Authority has been closely monitoring the situation, however, as we do not currently have sufficient information from the flight data recorder we have, as a precautionary measure, issued instructions to stop any commercial passenger flights from any operator arriving, departing or overflying UK airspace."The UK Civil Aviation Authority's safety directive will be in place until further notice."We remain in close contact with the European Aviation Safety Agency (EASA) and industry regulators globally."In a statement, Singapore's Civil Aviation Authority announced it would suspend all variants of the Boeing 737 Max aircraft from entering or leaving the city-state, a move affecting SilkAir, China Southern Airlines, Garuda Indonesia, Shandong Airlines and Thai Lion Air.While no Australian airlines fly the 737 MAX, Australia's Civil Aviation Safety Authority said it would temporarily suspend airlines from flying all Boeing 737 MAX jets to or from Australia.Oman said on Twitter it is temporarily suspending operations of Boeing 737 MAX aircraft into and out of its airports until further notice.Malaysia announced that it would suspend the MAX 8 aircraft flying to or from and transiting the country until further notice. No Malaysian carriers currently operate the model.Airlines including Ethiopian Airlines, Aeromexico, Cayman Airways, South Africa's Comair, South Korea's Eastar Jet and Aerolíneas Argentinas and all Indonesian airlines have said they are temporarily not using the 737 MAX 8.Those decisions follow the lead of China's aviation administration, who on Monday ordered that all domestic Boeing 737 MAX 8 jets be out of the air by 6 p.m. local time, due to its principle of "zero tolerance for safety hazards."China has one of the world's largest fleets of Boeing 737 MAX 8, operating 97 of the planes, according to Chinese state-run media.The fallout has appeared to affect Boeing's bottom line. The aircraft maker's stock dropped 8% Monday, with investors voicing concerns about the 737 and 3173
