Boeing shares fell during Tuesday morning trading amid renewed safety concerns over its 737 max jet after a second deadly crash.

On Sunday an Ethiopian airlines Boeing 737 max crashed, killing all 157 people on board the flight.

This follows a similar incident involving another of the company’s 737 max planes back in October last year, in which a Lion air flight crashed only 12 minutes after taking flight.

Both Singapore and Australia’s aviation authorities have since taken the decision to suspend any Boeing 737 max from flying to or from their countries.

As it stands, the aeroplane manufacturer has received 5,000 orders for the 737 Max, having already completed 300 737 Max aircraft orders since March 2018.

Boeing have issued the following statement regarding Sunday’s crash:

“Boeing is deeply saddened to learn of the passing of the passengers and crew on Ethiopian Airlines Flight 302, a 737 MAX 8 airplane. We extend our heartfelt sympathies to the families and loved ones of the passengers and crew on board and stand ready to support the Ethiopian Airlines team. A Boeing technical team will be travelling to the crash site to provide technical assistance under the direction of the Ethiopia Accident Investigation Bureau and U.S. National Transportation Safety Board.”

Shares in the American firm (NYSE:BA) are currently down -5.33% as of 10:36AM (GMT).
